Description

 Parking assist system for two-wheeled vehicles and control method therefor  

The subject matter described herein relates generally to a parking assist system for a two-wheeled vehicle, and particularly, but not exclusively, to a control method therefor.

Parking for vehicles is often challenging for the driver, as it involves maneuver between other parked vehicles, especially on crowded roads. However, in some cases it is required to maneuver between two vehicles parked in an end-to-end manner, in some other cases requiring the vehicle to be maneuvered in two vehicles parked parallel to each other in a side-by-side manner. between. Typically, some of the factors that affect maneuverability include the size of the parked vehicle, the radius of rotation of the parked vehicle, the speed at which the vehicle is parked, and the like.

In order to facilitate the driver's easy parking, the four-wheeled vehicle is typically equipped with a parking assist system that guides the driver to the vehicle by indicating to the driver the current direction in which the vehicle is traveling in relation to the parked vehicle. Park properly. However, parking assist systems are not commonly used in two-wheeled vehicles, and two-wheeled vehicles are typically manually pushed to park; such as a vehicle that is assembled to be powered by an internal combustion engine or a traction motor or both, and An electric vehicle that is powered by a traction motor. In addition, the hybrid/electric two-wheeled vehicle is more difficult to push due to the larger cogging torque of the traction motor than a typical two-wheeled vehicle. In addition, the hybrid two-wheeled vehicle system is also significantly heavier than the average two-wheeled vehicle. As a result, it was inconvenient to push the hybrid/electric vehicle to a parking lot. Moreover, since the initial power/acceleration system usually provided by the hybrid/electric two-wheeled vehicle is high, it is difficult to control the vehicle system for parking.

Some prior art techniques have revealed the use of parking assist systems in two-wheel hybrid/electric vehicles. However, there are some problems in the known parking assist systems. For example, in some hybrid/electric vehicles in which the parking assistance system is known, it is necessary to inform other drivers, pedestrians or even the vehicle operator itself that the vehicle is moving in a parking mode, especially in the reverse direction. A parking indicator system that moves in the direction is unknown. The lack of a parking indicator system is thus proven to be a safety risk. Moreover, in some hybrid/electric vehicles, the operation of the parking assist system that facilitates reverse parking by moving the vehicle in the reverse direction is known, wherein the parking assist system is merely pressed by a button/parking switch. start up. However, if the vehicle operator inadvertently presses the parking switch, the vehicles are in danger of moving automatically in the reverse direction.

Accordingly, it is desirable to provide a parking assist system for a two-wheeled vehicle, particularly for a two-wheel hybrid/electric vehicle having improved safety features.

In one aspect, the present invention provides a method for controlling the output power of a traction motor (53) of a two-wheeled vehicle that is adapted to operate in different modes of operation and includes one or more power sources, an electronic control unit (50) with a cluster (52); wherein the electronic control unit is configured to control the output power delivered to the traction motor (53) to activate the vehicle; the method comprises the steps of: when an ignition switch ( 51) in an ON state, detecting whether a parking switch (56) of the vehicle is in an ON state; when the ON state of the parking switch is detected, selecting a parking assist mode and placing a parking mode signal Transmitting to a plurality of dangerous lamps (57); communicating the selection of the parking assist mode to the electronic control unit (50) by the instrument cluster (52), and starting the parking assist mode; by the control unit ( 50), at the beginning of the parking assist mode, check vehicle parameters such as vehicle speed, throttle position, brake ON/OFF state, and rotation angle of a rear wheel; by the control unit (50), when a Controlling the output power delivered to the motor (53) when the predetermined condition of the group and one of the predetermined conditions of the second group are satisfied after the start of the parking assist mode; and operating the vehicle at the parking assist In the mode, a parking indication signal is transmitted to the instrument cluster (52) by the control unit (50).

The present invention has been devised in view of the above problems.

One object of the present invention is to provide a parking assist system for a two-wheeled vehicle.

Another object of the present invention is to provide a parking assist system for a two-wheeled vehicle that can assist the vehicle in moving in a forward or reverse direction in a parking assist mode.

Yet another object of the present invention is to provide a parking assist system that includes an electronic control unit that is configured to control the power delivered to a traction motor of the vehicle for either a forward or reverse direction. Start the vehicle.

Still another object of the present invention is to provide a parking assist system that includes an electronic control unit that is configured to transmit a parking indication signal to a cluster of meters for notification of selection of a parking assist mode.

Still another object of the present invention is to provide a parking assistance system including an electronic control unit that is configured to transmit a parking signal to a plurality of dangerous lights of the vehicle for notification of selection of a parking assist mode .

In view of the above and other objects, the present invention provides a two-wheeled vehicle that includes a parking assist system for assisting movement of the vehicle in a forward or reverse direction in a parking assist mode. According to one aspect of the invention, the parking assistance system includes an electronic control unit that assists in the parking assist mode to assist in the movement of the vehicle in a forward or reverse direction. In particular, the electronic control unit functions to assist the vehicle in a parking assist mode by controlling the output power delivered to a traction motor of the vehicle. For example, the electronic control unit functions to control the output power delivered to the traction motor of the vehicle, based on vehicle speed, throttle position, braking conditions, and the like, received from, for example, a Hall sensor, throttle position Sensors, brake switches and similar vehicle sensors; enabling a vehicle operator to have better control of the vehicle while parked.

In particular, in accordance with an embodiment of the present invention, the electronic control unit functions to operate when one of the parking switches of the vehicle is in an ON state and the predetermined condition of the first group is satisfied with one of the predetermined conditions of the second group And control the output power delivered to the traction motor. In one embodiment, the predetermined condition of the first set is satisfied when the vehicle speed is below the first threshold vehicle speed and the throttle position is in an open state. Therefore, when the control unit detects the predetermined condition of the first group, the control unit causes the vehicle to operate in the parking assist mode in a forward direction. Thus, since the output power delivered to the traction motor is controlled, it is ensured that the vehicle is moving at a first preselected speed that is less than the first threshold vehicle speed. In other words, the vehicle is caused to move at a lower speed when it is operating in the parking assist mode, thus providing better control of the vehicle by the vehicle operator during parking and enabling easy handling of the vehicle during parking.

Similarly, the electronic control unit acts to control the output power delivered to the traction motor when the predetermined condition of the second set is satisfied and causes the vehicle to move in a reverse direction. According to an embodiment of the present invention, the predetermined condition of the second group is when the vehicle speed is zero, the throttle position is in a closed state, the brake is in an OFF condition, and the rotation angle obtained by a rear wheel of the vehicle is A predetermined degree of rotation (for example, a quarter turn of the rear wheel rotation) is satisfied. In other words, the predetermined condition of the second group is satisfied when the vehicle is manually pushed backwards, whereby the electronic control unit detects a quarter of the rear wheel reversal and causes the vehicle to move in a reverse direction. . Thus, when the vehicle operator pushes the vehicle in a reverse direction to stop, the electronic control unit automatically causes the vehicle to move in a reverse direction at a second preselected speed. The provision of the above features also facilitates easy removal of the vehicle from a parked state. According to an embodiment of the invention, the second preselected speed of the vehicle is less than the first preselected speed. In other words, the vehicle moves at a lower speed in the reverse direction than in the forward direction, thus ensuring the safety of the vehicle and the vehicle operator. At the same time, however, since a minimum amount of power is supplied to the traction motor, it is ensured that the vehicle can be moved in the reverse direction without too much effort, which would otherwise be difficult to manually push, especially on the uphill The situation. In particular, since a manual intervention of the vehicle is pushed in the reverse direction, the electronic control unit is involved in driving the vehicle in the reverse direction, ensuring that there is no parking alone. Inadvertent movement of the vehicle in the reverse direction by pressing/selecting of the switch.

According to another aspect of the present invention, in the two-wheeled vehicle, the parking open relationship and a dangerous switch are combined. Therefore, when the parking open relationship is switched ON, a plurality of dangerous light systems start to emit light. Therefore, it is ensured that when the vehicle is operating in the parking assist mode, the passerby/pedestrian is alerted and alert.

According to still another aspect of the present invention, a parking indication signal is transmitted from the electronic control unit to the instrument cluster of the vehicle. In particular, in one embodiment, the parking indication signal provided to the instrument cluster can be a visual indication that includes text and color indications; and in another embodiment, the parking indication signal system is provided Can be an audible indication.

Furthermore, the present invention also describes a method of operation of the electronic control unit for controlling the output power delivered to the traction motor when the parking switch is switched ON.

The above summary is provided to illustrate the essential features of the invention and not to limit the scope of the invention.

Accordingly, the subject matter described herein is directed to a parking assist system for a two-wheeled vehicle that enables the vehicle to be easily parked and ensures appropriate safety measures. In particular, the parking assistance system includes an electronic control unit, such as a hybrid control unit, for controlling the output power delivered to a traction motor such that the vehicle system can be at a first preselected speed and Second, one of the pre-selected speeds is operated in a parking assist mode in a forward direction or a reverse direction.

In particular, the internal combustion engine 14 is supported by a swing arm 19. The swing arm 19 is attached to a bottom of the main pipe 15B by a toggle link (not shown). The other end of the swing arm 19 holds the rear wheel 27. The rear wheel 27 and the swing arm 19 are coupled to the pair of side frames 15C by one or more shock absorbers 30 disposed on each side of the vehicle 10.

The hybrid vehicle 10 further includes a traction motor 53 mounted on a hub of the rear wheel 27. The traction motor 53 is actuated by a battery (not shown) disposed at a rear end portion of the vehicle. However, in another embodiment, the battery system can be disposed at a front end portion of the vehicle. An electronic control unit 50 (shown in Figure 2) is also provided to control a variety of vehicle operating modes.

The hybrid vehicle 10 is assembled to be propelled by the engine 14 alone or by the traction motor 53 alone, or simultaneously by the engine 14 and the traction motor 53. At zero vehicle speed, a driver can select any of the following four operational drive modes by means of a mode switch. The four operational drive modes of the hybrid vehicle 10 are: (a) a single engine mode in which the vehicle is launched by the engine 14 alone; (b) a separate motor mode in which the vehicle is solely powered by the traction motor 53 (c) a hybrid launch mode in which the engine 14 is started with the traction motor 53; (d) a hybrid economy mode in which only the engine 14 or only the traction motor 53 is selected depending on vehicle operating conditions. Or both to launch the hybrid vehicle.

In other words, the rear wheel 27 of the vehicle is driven solely by the engine 14 or by the motor 53 alone or by the engine 14 and the motor 53 at the same time. In particular, in accordance with an embodiment of the present invention, the powertrain from the engine 14 to the rear wheel 27 is transmitted by a transmission assembly (not shown) that includes a drive system. However, when the traction motor 53 is driven, the power from the motor 53 is directly transmitted to the rear wheel 27. In the present embodiment, the traction motor 53 is covered by at least one side and by a motor shroud (not shown).

The vehicle 10 as described above is adapted to operate in a parking assist mode by a parking assist system P provided thereto.

Referring to Figure 2, there is illustrated a schematic representation of a parking assist system P in accordance with one embodiment of the present invention. The parking assist system P includes an electronic control unit 50 that is assembled to be connected to various components such as the instrument cluster 52, the traction motor 53, and the battery 60, and is connected to include an ignition switch 51 and a throttle position sensor. 54. The brake switch 55, the parking switch 56 and a plurality of similar vehicle sensors and vehicle switches are used to receive various inputs relating to vehicle operating conditions. In particular, the electronic control unit 50 communicates with the components, the sensors, and the switches via a controller area network (CAN). Some of the above-described components, such as battery 60 and meter cluster 52, may include their own controllers. For example, the battery 60 can have a battery control module (BCM) or a battery management system (BMS) that transmits and receives signals to and from the battery 60 and the electronic control unit 50. In the present embodiment, the instrument cluster 52 includes a first microcontroller for communicating with the electronic control unit 50. Furthermore, the traction motor 53 and one or more Hall sensors are integrated for communication with the electronic control unit 50. Furthermore, the electronic control unit 50 is operatively coupled to the battery 60 and the traction motor 53. Although the battery 60 is powered to the electronic control unit 50, the power delivered from the battery 60 to the traction motor 53 is controlled by the electronic control unit 50.

In the present embodiment, the instrument cluster 52 includes a first microcontroller that is connected in a phase-by-CAN communication to an electronic control unit 50 having a second microcontroller. Based on the information received from the plurality of vehicle sensors/switches, the electronic control unit 50 provides vehicle information, which is then processed by the first microcontroller for display on the cluster 52. The instrument cluster 52 provides various vehicle operation related information to the vehicle operator, for example, drive mode operation, parking mode operation, battery state of charge, and the like. In doing so, the cluster 52 represents the vehicle in a schematic or graphical representation. The schematic or image representation provides a better concept for the vehicle operator as to how the vehicle is operating and whether there are any faults in the vehicle, and is therefore more appropriate than a conventional analog or digital display device and it works.

For example, in the present embodiment, when the electronic control unit 50 activates a parking assist mode, it communicates to the instrument cluster 52, and a visual indication in the form of a visual text is provided in the instrument cluster 52 to notify The vehicle operator has an operation regarding the vehicle in the parking assist mode. Moreover, when the parking switch 56 is selected, one signal is transmitted to a plurality of dangerous lamps 57, and the plurality of dangerous lamps 57 start to emit light, and the other vehicles/pedestrians are given a warning that the vehicle will move slowly.

The method of operating the parking assist system P in accordance with one embodiment of the present invention is described in detail with reference to FIG. In particular, Figure 3 illustrates the operational steps of the first microcontroller and electronic control unit 50, which are indicated in the cluster 52, for operating the vehicle in the parking assist mode. Initially, it is to be noted that some of the steps in flowchart 99 can be implemented in a different order, including at the same time. In addition, the steps shown in flowchart 99 are ongoing and need not end at the last step.

At block 100, in a first step of its operation, electronic control unit 50 determines if the ignition switch 51 is in an ON/OFF state. When the ignition switch is in the ON state and the vehicle operator switches the parking switch to ON, the first microcontroller in the cluster 52 is detected at block 101 to detect the ON of the parking switch. State, and at block 102, the parking assist mode is selected. In particular, in accordance with one aspect of the present invention, the parking switch input is transmitted to the instrument cluster when the parking relationship is selected. The parking mode signal is also transmitted to a plurality of dangerous lights, causing the light to be illuminated. Thereafter, at block 103, the first microcontroller of the instrument cluster also communicates with the electronic control unit via the CAN communication that the parking assist mode is selected. In other words, it is communicated via CAN communication that the vehicle drive mode has changed to the parking assist mode. The vehicle continues to operate in the existing drive mode when the parking assist mode is not selected by switching the parking switch to ON. Moreover, when the electronic control unit detects that the parking assist mode is selected, it is determined whether the existing vehicle operating condition is suitable for the vehicle operation in the parking assist mode. For example, in accordance with one aspect of the present invention, the electronic control unit checks whether the predetermined condition of the first group or the predetermined condition of the second group is satisfied, thereby enabling operation of the vehicle in the parking assist mode. According to one embodiment, the predetermined conditions of the first group are set at blocks 104 and 105, and the predetermined conditions for the second group are set at blocks 107, 108, and 109. After detecting the predetermined condition of the first group or the predetermined condition of the second group as described above by the ECU, the parking mode indication signal is transmitted to the instrument cluster, whereby the instrument cluster is displayed in a display panel "Parking assist ON".

In the present embodiment, at block 104, the electronic control unit checks the vehicle speed whether the vehicle speed is zero or below the first threshold speed. If the vehicle speed is zero or lower than the first threshold speed, the electronic control unit initiates the parking assist mode. In other words, the electronic control unit ensures that the selection of the parking switch by the vehicle operator is intentional prior to enabling the parking assist mode. In particular, in the present embodiment, the input regarding the speed of the vehicle is provided to the electronic control unit by one or more Hall sensors disposed in the traction motor. In this embodiment, the first threshold speed may be in the range of 8-10 km/h.

Again, at block 105, the electronic control unit checks the throttle position. If the throttle position is open, at block 106, the electronic control unit enables operation in the parking assist mode in a forward direction with a first preselected speed in the range of 5-6 km/h. At the same time, a signal system is also transmitted to the instrument cluster in the form of a visual text or a backlit color...etc.

However, if the throttle system is closed, the electronic control unit checks the conditions set at block 107. At block 107, the electronic control unit checks if the vehicle speed is zero, if the throttle position is closed, and if the brake input is in an OFF condition. If the condition set at block 107 is satisfied, at block 108, the electronic control unit checks the reversal of the rear wheel. The input relating to the reversal of the rear wheel is received by the electronic control unit from the one or more Hall sensors disposed in the traction motor. In the present embodiment, when a predetermined rotation angle (for example, 90°) is detected by the rear wheel, the electronic control unit enables the parking assist mode to be in the reverse direction. In other words, before enabling the parking assist mode to be in the reverse direction, the electronic control unit checks whether the vehicle operator has pushed the vehicle at least slightly in the reverse direction until the 90° rotation is obtained at the rear wheel. Furthermore, at block 109, the electronic control unit also checks if the vehicle speed is greater than the second threshold speed, for example: greater than 2-3 km/h. If the vehicle speed is not greater than the second threshold speed, the electronic control unit enables operation of the parking assist mode to be in a reverse direction at a second preselected speed in the range of 3-4 km/h. At the same time, a signal system is also transmitted to the instrument cluster to display the parking sequence in the form of a visual text or in the form of a backlit color. However, if the vehicle speed is greater than the second threshold speed, the electronic control unit activates the electric brake. This ensures that when the vehicle operator attempts to park the vehicle on a downhill slope, the vehicle will not begin to decelerate due to the additional power provided to the traction motor in the parking assist mode. Thus, when the vehicle speed is greater than the second threshold speed, the brake application is a safety feature when the vehicle operator attempts to park the vehicle on a downhill slope. Furthermore, when the parking assist mode in the reverse direction is enabled, at block 111, the electronic control unit also checks if the current supplied to the traction motor exceeds a threshold current. If the control unit detects that the current supplied to the traction motor exceeds the threshold current, the control unit stops the current/power supply to the traction motor. This is especially useful when the motor encounters a large load; for example, when the vehicle operator suddenly tries to stop the vehicle on a downhill condition without applying a brake, the larger The load is encountered. Therefore, in order to prevent acceleration of the vehicle, especially in a downhill condition, the electronic control unit is also equipped to detect current/electric power supplied to the motor that is greater than the threshold current, so that the vehicle moves safely in the reverse direction. .

The present invention therefore proposes a method for assisting the movement of the two-wheeled vehicle in a forward or reverse direction in the parking assist mode. Since the present invention helps to optimize the power delivered to the traction motor when the parking assist mode is enabled, the vehicle operator can find that it is convenient to control and operate the vehicle during parking. Moreover, since at least some minimum amount of powertrain is supplied to the traction motor, the vehicle operator does not have to labor the cart during parking.

Although the present invention has been shown and described with respect to the foregoing preferred embodiments, it will be apparent to those skilled in the art The spirit and scope of the invention as defined.
