Description

Vehicle Acceleration and Braking Integrated Device

technical field

The invention relates to a control device for an automobile, in particular to an integrated device for accelerating and braking a vehicle.

Background technique

At present, the speed control of automobiles on the market mostly adopts a driving method similar to that of traditional automobiles, and the speed of the automobile is controlled through devices such as accelerator pedals and brake pedals. There are mainly two following problems in this car that is provided with two pedals:

First, the operation complexity is high. Driving this electric vehicle needs to be familiar with the accelerator pedal and the brake pedal at the same time, and learning the driving of this electric vehicle requires a long process, which is not conducive to quickly mastering driving skills.

Second, it is easy to cause misoperation. Since the accelerator and brake pedals have opposite functions, sometimes pressing the wrong pedal can have disastrous results. For example, in the case of emergency braking, the driver may mistakenly use the accelerator pedal as the brake pedal due to panic, causing traffic accidents.

There are several devices for controlling automobile acceleration and braking with a single pedal at present, and a purely mechanical control method is arranged, utilizing a lever mechanism, the downward movement of the sole of the foot is braking, and the downward movement of the heel is acceleration. There is also a purely mechanical control method, the initial state is the brake, and when the pedal is stepped on to a certain extent, it enters the acceleration operation. Finally, release the pedal and return the pedal to the braking state by a weight. There is also a way of binding the feet. The foot is pulled to control the accelerator, and the foot is stepped to control the brake. The mechanical structure is relatively complicated, and the long-term pulling state increases the fatigue of the driver and reduces the safety of driving. . In addition, some acceleration and braking devices require a combination of multiple pedals, which increases the complexity of the operation. The control mode adopted in the above patents is completely different from this patent. In addition, some devices, like this patent, start and accelerate when lifted, decelerate and brake when stepped on, but their mechanical structures are complex, which not only increases the difficulty of design and manufacture, but also makes it difficult for drivers to grasp the essentials of use. Therefore, it is necessary to develop a novel device with a simpler structure.

detailed description

The present invention will be further described in detail below in conjunction with the examples.

Example 1

The vehicle acceleration and braking integrated device, as shown in Figures 1 and 2, includes an acceleration device 100 and a braking device 200. The acceleration device in this embodiment usually refers to a device that adjusts the fuel supply, and is used in automobiles or other similar motor vehicles. The top is the gas pedal; the braking device 200 is a device for stopping or reducing the speed of running locomotives, vehicles and other means of transport or machinery. By fixing a wheel or disc on the high-speed shaft of the machine, installing corresponding brake shoes, belts or discs on the machine base to generate braking torque under the action of external force, the acceleration device 100 is provided with a pedal 101, The pedal 101 is hinged with the accelerator device 100, the pedal 101 controls the acceleration of the vehicle by changing the relative position between itself and the accelerator device 100, and when the pedal 101 moves to the preset position 300, the brake device 200 is triggered to realize braking of the vehicle.

The vehicle acceleration and braking integrated device also includes a state switching device 400; the state switching device 400 includes a master device 401 and a slave device 402, and the master device 401 reciprocates along a certain track relative to the slave device 402. A certain track refers to a moving track formed by a guide groove 4011 or a rotating shaft, and the active device 401 can reciprocate along the track under the action of the pedal 101 to realize the control of the accelerator device 100; the active device 401 and the pedal 101 connected, the driven device 402 is connected with the braking device 200; the preset position 300 is the position when the active device 401 moves to the closest to the driven device 402, and the preset position 300 can be the position of the active device 401 A certain point on the motion track can also be the end point of the motion track. When the active device 401 moves to the preset position 300 or moves forward beyond the preset position 300, the braking device can be triggered. , the brake lever 201 or the transmission lever of the brake device 200 can be pushed in order to realize the brake operation on the vehicle.

The driving device 401 is provided with a guide groove 4011 , and the driven device 402 is provided with a sliding member 4021 that can slide in the guide groove 4011 .

The driven device 402 is provided with a guide groove 4011 , and the active device 401 is provided with a sliding member 4021 that can slide in the guide groove 4011 . Generally speaking, the guide groove 4011 can be arranged on the driving device 401 or the driven device 402 , but considering the convenience of equipment replacement, it is better to arrange the guide groove 4011 on the driving device 401 . In this embodiment, the active device 401 is connected to the pedal 101 , so the acceleration device 100 and the brake device 200 can be connected only by replacing the pedal 101 .

The active device 401 is fixedly connected to the pedal 101, the driven device 402 is fixedly connected to the braking device 200, and the active device 401 is fixed on one side of the pedal 101, or one side of the pedal 101 protrudes toward the outside of the pedal 101. Partly, the structural strength between the active device 401 and the pedal 101 is improved.

The guide groove 4011 includes a first guide section 4012 and a second guide section 4013 , the first guide section 4012 is located away from the preset position 300 relative to the second guide section 4013 . When the slider 4021 slides in the first guide section 4012, the pedal 101 controls the acceleration device 100 to accelerate the vehicle, and when the slider 4021 is located in the second guide section 4013, the position change of the pedal 101 does not trigger Acceleration of the vehicle, and at this time the position of the slider 4021 has not reached the preset position 300, so the braking device 200 will not be triggered, thus providing an isolation area between the accelerating device 100 and the braking device 200 , can effectively prevent the vehicle from losing control caused by the sudden transition between the acceleration and braking states. Further, the second guide section 4013 includes an action feedback device 4014, and the action feedback device 4014 can provide the slider 4021 with a movement direction opposite to the movement direction of the slider 4021 when the slider 4021 slides in the second guide section 4013. force. The action feedback device 4014 can be a rough surface arranged on the inner side wall of the guide groove 4011 or a spring or similar device connecting the guide groove 4011 and the sliding member 4021, and the active force provided by the action feedback device 4014 comes from the rough surface Friction or spring force. The main function of the action feedback device 4014 is to provide a direct feedback perception, which not only allows the driver to know the approximate position of the current sliding member 4021, but more importantly, when the driver steps on the pedal 101, the sliding member 4021 enters the second guide section At 4013, the driver can clearly perceive a relatively strenuous stage, so the driver needs to step on the pedal 101 with a relatively greater strength to make the pedal 101 slide through the second guide section 4013, which can prevent some sudden Situations, such as those in which the active device 401 accidentally triggers braking due to a sudden jerk of footsteps.

The guide groove 4011 is: when the slider 4021 moves from one end of the guide groove 4011 to the other end, a groove is formed along the moving track of the slider 4021 relative to the guide groove 4011, especially, the guide groove 4011 is an arc-shaped groove. When the pedal 101 rotates around the acceleration device 100, it drives the guide groove 4011 to move relative to the sliding member 4021, so the arc-shaped guide groove 4011 is an arc-shaped groove with the accelerator device 100 as the center, and the radius of the arc should be roughly the same as the sliding The distance from the part 4021 to the acceleration device 100 is equal. If the thickness of the side wall of the guide groove 4011 is considered, the radius of the arc should be larger, at least the thickness of the side wall of the guide groove 4011 should be added.

A vehicle is equipped with the above-mentioned vehicle acceleration and braking integrated device, which can realize acceleration or braking operation under the condition of a single action.

In addition, this embodiment also includes a method for integrated control of acceleration and braking of a vehicle, including the following specific steps: divide the stroke of the pedal 101 into three stages, and perform different controls in different stages, wherein , the first stage is the acceleration stage, when the pedal 101 is started to be stepped on, the vehicle is controlled to accelerate and accelerate according to the stroke distance moved after the pedal 101 is stepped on; the second stage is the braking stage, when the driver steps on the pedal 101 to exceed the preset After the position is 300, the vehicle is braked by controlling the travel distance of the pedal 101 after being stepped on; in addition, it also includes an intermediate stage, which is located between the acceleration stage and the braking stage. When the pedal 101 travels at this In the stage, no acceleration or braking operation is performed on the vehicle, and at this time, the vehicle moves forward under the action of inertia. The pedal 101 can flexibly switch between the above three stages. In addition, when the moving stroke of the pedal 101 is in the part of the acceleration stage close to the middle stage, a feedback signal needs to be fed back to the driver to remind the driver that the moving stroke of the pedal 101 is approaching the braking stage, so as to attract the attention of the driver. The feedback signal can be directly fed back to the foot of the driver stepping on the pedal 101 through the pedal 101 in the form of reaction force, or can be fed back in the form of vision or hearing.

In a word, the above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the patent of the present invention.
