Description

TITLE

VIBRATION ALERT ON A WEARABLE FOR VEHICLE CRITICAL INFORMATION OF 2 -WHEELERS

The current invention relates to a wearable motorcycle equipment, a corresponding alert system and to an alert communication unit. The wearable is capable of generating an alert in response to a received vehicle operating condition.

Wearable computers, also known as body-borne computers or wearables are miniature electronic devices that are worn by the bearer under, with or on top of clothing. Wearable computers are especially useful for applications that require more complex computational support than just hardware coded logics. The current moves in standardization with IEEE, IETF and several industry groups (e.g. Bluetooth) leads to more various interfacing under the WPAN (wireless personal area network) and the WBAN (Wireless body area network) offer new classification of designs for interfacing and networking.

In the context of the present specification, the expression "wearable" refers to a garment or to a wearable accessory that comprises a computing means, a means for wireless communication and a vibration generator, wherein the means for wireless communication and the vibration generator are connected to the computing means. In particular, the computing means is capable of processing alert messages of a motor cycle and to generate a corresponding signal.

Similar functions can also be provided by textiles . E- textiles, also known as electronic textile smart textiles , or smart fabrics, are fabrics that enable digital components and electronics to be embedded in them. Many intelligent clothing, smart clothing, wearable technology, and wearable computing projects involve the use of E-textiles .

The present specification discloses a motor cycle alert sys tern comprising an alert communication unit and a wearable. The alert communication unit comprises an interface for receiving signals from an instrument cluster of a motor cycle a sender antenna, which is connected to the interface, and power connection for connecting to an electric power system of the motor cycle.

The alert communication unit can access information, which is displayed on the instrument cluster, in a convenient manner by receiving and evaluating the signals of the instrument cluster. By way of example, the alert communication unit can access the information by connecting to an automotive data bus or by tapping electric cables. The alert communication unit may also use the automotive data bus or the electric cables to access further information, which is not displayed on the instrument cluster.

Thereby, the alert communication unit can make use of information that is already available through the electronics of the motor cycle without the need to provide an extra sensor. Moreover, the alert communication unit does not need to provide its own battery but can be connected to an electric power supply of the motor bike, although a battery may be provided .

On a receiver side, the alert system comprises a wearable for a motor cycle driver. The wearable comprises a receiver an- tenna, a vibration generator and a processing unit and, which is connected to the receiver antenna and to the vibration generator .

The alert communication unit is operative to generate an alert signal based on a pre-determined motor cycle operating condition and to transmit the alert signal over the sender antenna of the alert communication unit. The pre-determined operating condition is derived from signals of the instrument cluster, such as signals from an automotive data bus of the instrument cluster, signals from electric cables of the instrument cluster, and signals from a cable being connected to a sensor on the motor cycle.

The processing unit of the wearable is operative to receive the alert signal over the antenna of the wearable and to cause the vibration generator to generate a vibration alert signal. Preferentially, the vibration generator is placed close to the body of a driver so that the driver can sense the vibration.

The sender antenna and the receiver antenna are both capable of receiving and transmitting electromagnetic signals . In one embodiment, the alert system is designed as a one-way communication system, wherein a transmitter is connected to the sender and antenna and a receiver is connected to the receiver antenna. In another embodiment, the alert system is designed as a two-way communication system, wherein a first transceiver is connected to the sender antenna and a second transceiver is connected to the receiver antenna.

In a further embodiment, the communication unit is provided with suitable attachment means, such as bores, screw holes, straps, catches, attachment surfaces or other, which are provided for an attachment of the communication unit to a motor cycle, in particular for the attachment to an upper front portion of the motor cycle. Thereby, the communication unit can be used for retro-fitting to a motor cycle.

In the context of the present specification an "instrument cluster" may refer to a digital instrument cluster but also to the set of indicators that is provided by an analog dashboard, such as tell-tale diodes and indicator needle based instruments, or to a combination of a digital instrument cluster and analog instruments.

In one embodiment, the interface comprises a connection for receiving digital data from an automotive data bus such as a CAN bus, a LIN bus, a Flexray bus or the like. A second processing unit of the motor cycle electronics, such as an engine control unit, a driver-assistance control unit or the like is connected to the automotive data bus. The second processing unit may also be connected to the interface via a separate cable. In particular, the second processing unit can be connected to one or more sensors of the motor cycle.

Alternatively or in addition to the data bus connection, the interface of the communication unit comprises at least one wire-tapping unit. The wire-tapping unit comprises a casing for holding a wire of the instrument cluster, a movable part that is connected to the casing, a tapping blade that is connected to the movable part, and a tapping wire that is electrically connected to the tapping blade. The tapping wire is connected to the communication unit, and the wire is connected to the instrument cluster. In one embodiment, the wearable comprises a smart bracelet or a smart watch. According to further embodiments, the wearable comprises a smart helmet, a smart jacket, a smart leg protector, a smart knee protector or smart motor cycle pants.

In a further aspect, the present specification discloses an alert communication unit for a motor cycle. The alert communication unit comprises a transceiver, an antenna and an interface for receiving signals from an instrument cluster of the motor cycle. The communication unit is operative to evaluate the signals of the instrument cluster, to derive an alert message from the received signals and to control the transceiver and the antenna to transmit the alert message over a wireless connection, such as a RF connection or a short range WLA connection.

In one embodiment, the interface comprises means to receive digital signals from a digital instrument cluster or from a digital communication bus of the motor cycle, such as a digital signal decoder. In another embodiment, the interface comprises the abovementioned wire-tapping device or unit, which is provided alternatively or in addition to the signal decoder .

Furthermore, the current specification discloses a motor cycle with an instrument cluster and the aforementioned alert communication unit . The interface of the alert communication unit is connected to the instrument cluster.

In a further aspect, the current specification discloses a wearable for a motor cycle alert system. The wearable comprises an antenna, a processing unit and a vibration generator, which is connected to the antenna and the vibration gen- erator. The processing unit of the wearable is operative to receive an alert signal over the antenna of the wearable and to cause the vibration generator to generate a vibration alert signal, which is indicative of an operating condition of a motor cycle.

In particular, the wearable can be provided by a smart wearable accessory, such as a smart watch or a smart bracelet.

In further embodiments the wearable comprises a smart helmet, a smart jacket or smart motor cycle pants, or a smart leg or knee protector.

The electronic components of the wearable are preferably placed at a location where they are well protected, allow good wireless communication and are suitable for transmitting a vibration to the driver's body. In the case of garments, such as motor cycle jacket or pants, the equipment is also suitably protected or ruggedized against damage from cleaning and drying. In further embodiments, the wearable also comprises body sensors for measuring pulse rate, eye movement and other body parameters .

In particular, the vibration generator of the smart helmet may comprise a loudspeaker, which can be a dedicated loudspeaker or a loudspeaker that is provided for other functionalities as well. In one embodiment, the smart helmet comprises an alert display, which is integrated in a transparent visor of the helmet, wherein the processing unit is operative to display an optical signal on the alert display in response to the received alert signal. The alert display of the smart helmet can be switched off for power saving purposes or to avoid a distraction of the driver. A notification of a vehicle condition through a vibration generator of a wearable according to the current application can relieve the driver from the need of constantly watching the display and the driver can focus his or her attention to other aspects such as watching the events on the road.

Often, the attention of the driver is focused mainly on the speed. A wearable which is capable of generating an alert through vibration and/or acoustic signals is able to direct the attention of the driver to the alert. Once the driver is alerted in this way, the driver can inspect the instruments to get a more detailed information about the nature of the event or take an appropriate action. For example, motor cycle riders often fail to notice that the tires do not have enough pressure. The alert system according to the present application can contribute to road safety by helping the driver to detect the problem much earlier.

Among others, the conditions, which may cause a generation of an alert message, comprise engine malfunction, an ABS malfunction of an integrated or of a combined ABS, tyre pressure changes, battery alert status, oil-pressure, hydraulic pressure, status of lights and optical indicators such as fused head lights, tell-tale lights, direction indicator lights etc. Further conditions include low fuel, diesel glow plugs operating in the case of diesel motor cycle, air-bag system malfunction, speed radar detected, and service intervals for specific vehicle components .

According to specific embodiments, the vibrations can be cus- tomized for different types of alerts depending on a pre- determined or customizable priority. According to a further embodiment, the rider can also skip alerts or switch off specific alerts or all of them. Further user configurable settings include the intensity and duration of the alerts, their time interval and their vibration pattern. For example, the intensity and/or the frequency may increase and decrease according to a pre-determined pattern which the user can select or customize. If a microphone is provided, the processing unit of the wearable may be provided with a voice recognition software to adjust the settings over voice commands.

According to specific embodiments, the wearable uses a short range WLA , such as Bluetooth, to provide a wireless connection to the instrument cluster of the motor cycle. In particular, the wearable can use an energy saving connection such as low energy Bluetooth standard, which reduces the amount of wireless communication. According to another embodiment, the wearable provides a two-way radio frequency connectivity between the motor cycle and the wearable, which can consume less energy than a communication at a higher frequency.

An alert system according to the present specification can provide several advantages such as low cost, using off-the- shelf hardware, generic solution for all sorts of 2-wheeler vehicles, easy modification to accommodate enhanced functionality, easy integration in commercially available wearables or smart watches .

For example, a smart phone app or a pre-installed code for communicating with a communication unit on the motor cycle is provided in a memory of the smart watch. The smart phone app identifies signals from the alert system and manages the communication in an energy saving manner. According to one embodiment, the smart phone app informs the communication unit about a battery state of the smart watch and the smart watch and/or the communication unit adapts the signal power and signal frequency accordingly.

In a further aspect, the current specification discloses a method for wirelessly transmitting an alert signal from a motor cycle to a wearable, the alert signal being indicative of a pre-determined operating condition of the motor cycle .

A communication unit of the motor cycle receives at least on signal is received from an automotive data bus or from a cable of the motor cycle. A processing unit of the communication unit derives a pre-determined operating condition from the received at least one signal. The processing unit determines if a sending condition is fulfilled. If the sending condition is fulfilled, the communication unit of the motor cycle causes a sender antenna to emit a corresponding alert signal .

The sending condition may comprise, among others, a predetermined time interval, a pre-determined time interval which is dependent on a battery state of a wearable or on an alert level, a pre-determined alert level or a pre-determined alert type.

Furthermore, the current specification discloses a computer executable code or a computer program product for executing the sending method and a processing unit for a motor cycle, wherein a computer readable memory of the processing unit comprises the computer executable code.

Fig. 5 shows a motorcyclist 35 on a motorcycle 36. The motor cycle comprises a processing unit 37, which is connected, among others, to a motor 38, a front lighting 39 and to an antenna 40. The antenna 40 and the processing unit 37 are connected to a transceiver, which is not shown in Fig. 5.

In Fig. 5, the motorcyclist wears a smart motorcycle pant 30'. Similar to the smart motor cycle leg protector 30, the smart motorcycle pant 30' is equipped with an antenna, a processing unit and a vibration generator. For simplicity, only the antenna of the motorcycle pant 30' is shown in Fig. 5.

According to one embodiment, the processing unit 37, the antenna 40 of the motor cycle 36 and the corresponding antenna, processing unit and vibration generator of the wearables are operative for a one-way communication from the processing unit 37 of the motor cycle 36 to the wearable 10, 15, 20, 30, 30' only. According to another embodiment, the processing unit 37, the antenna 40 of the motor cycle 36 and the corresponding antenna, processing unit and vibration generator of the wearables are operative for a two-way communication between the processing unit 37 of the motor cycle 36 to the wearable 10, 15, 20, 30, 30'.

During operation, the processing unit 37 receives data, which characterizes an operating state of a component of the motor cycle 36, and transmits a corresponding message via the antenna 40. The processing unit 37 may transmit the messages in periodic intervals, or the transmission may be triggered by an operating condition of the motor cycle or by a request message from the wearable. Furthermore, a time delay of sending the message may depend on a priority or criticality of the message, which is determined by the processing unit 37.

According to one example, a sensor monitors a tank level is monitored and forwards a corresponding signal to the processing unit 37. The processing unit 37 sends an alert message via the antenna 40 if the tank level falls below a predetermined value. The smart helmet 15 receives the message via the antenna 16, displays a corresponding symbol in the display 18 and generates an alert signal with the vibration generator 17. Further operating conditions include, among others, cooling water temperature, intake of petrol and air, engine speed, engine torque, vehicle speed, brake condition, the motor cycle tilt etc.

According to a further example, the processing unit receives information about a road condition, for example by using temperature and humidity sensors or a vehicle camera of the motor cycle 36 and forwards a corresponding message to the wearable 10, 15, 20, 30, 30'.

In one embodiment, each of the tires comprises a tire pressure sensor that is capable of transmitting an alert message over a wireless connection. In one example, the pressure sensor comprises a switch that is only activated when the tire pressure is too low in order to save battery life. The tire sensor is configured to send signals to a communication unit of the motor cycle. The communication unit is provided next to the instrument cluster. The communication unit comprises the antenna 40, a transmitter or a transceiver and a processing means, such as a battery powered microcontroller. Fig. 6 shows a wire-tapping unit 41 for use in the alert system of Fig. 5. The wire-tapping unit 41 comprises a casing 42 with a longitudinal opening 43 for taking up a cable 44. The longitudinal opening 43 has the shape of a cylinder portion, which is open to the exterior of the casing 42 along a longitudinal section that is parallel to the axis of the cylinder portion .

Furthermore, the wire-tapping unit 41 comprises a pivotable part 45, which is rotatably connected to the casing 42. A connector 46 is electrically connected to the pivotable part 45. In other words, there is a conductive path between the connector 46 and the pivotable part. A tapping cable or wire

47 is connected to the connector 46. A blade 48 is provided on the pivotable part 45, which can be best seen in the cross section A-A of Fig. 8. The blade 48 comprises a conductive material .

The cable 44, which is connected to an instrument of the in- strument cluster of the motor cycle 36, comprises an isolation 49 and a conductive core 50.

In order to provide a tapping of the wire 44, the pivotable part 45 is rotated towards the casing 42 until the pivotable part 45 is locked in a closed position. During the rotation of the pivotable part 45, the blade 48 of the pivotable part 45 cuts into the isolation 49 of the wire 44 until the blade

48 contacts the conductive core 50 of the wire 44. When the pivotable part is in the close position, the tapping wire 47 is electrically connected to the conductive core 50 of the wire 44. The tapping wire 47 is connected to the communication unit, which is provided next to the instrument cluster. When an electric signal runs through the conductive core the change of voltage is transmitted over the tapping wire 47 to the communication unit. The communication unit evaluates the received signal, the change of the signal over time and/or oth er received signals and generates a corresponding alert message if a pre-determined alert condition is fulfilled. The alert message is encoded and transmitted over the antenna 40

For example, in the case of a wireless RF connection the alert signal can be encoded by an analog signal, which is amplitude modulated and/or frequency modulated. In the case of a short range WLAN, the alert signal can be encoded by a digital signal. A digital signal refers to an electromagnetic wave, wherein parameters of the emitted electromagnetic wave such as frequency, amplitude, polarisation, time interval between signals, signal duration or a spatial orientation or amplitude pattern take on discrete values, which correspond to discrete values of the alert signal.

According to an alternative embodiment, a sliding part is provided instead of the pivotable part.
