Problems solved by technology
With the advancement of technology and the improvement of the requirements for car functions, as one of the few units in the car that can carry out human-computer information interaction, people hope that the accelerator pedal can achieve more functions; however, the ordinary accelerator pedal actually only serves as a one-way The role of information transmission, that is, the driver acts on the control intention to the car through the accelerator pedal, but the car cannot reverse the driving information to the driver through the accelerator pedal
In addition, different types of drivers tend to control the accelerator pedal differently in the actual road driving process, especially in the process of following the car on urban roads, resulting in differences in the driving speed, following time distance, and braking behavior of the own vehicle. Makes a big difference in performance and fuel economy
Under the same driving conditions, an aggressive driver will step on a larger amount of pedaling, resulting in a higher speed and a smaller following distance, in order to avoid accidents, and then issue more braking behavior; this Driving behavior is not only highly dangerous, but also causes huge waste of fuel, reducing the fuel economy of the car

The invention discloses an active feedback car accelerator pedal device and belongs to the technical field of car driving assisting systems. The device is mainly formed by a pedal support, a controller motor-small gear shaft system and a pedal rotary shaft system; the control motor-small gear shaft system and the pedal rotary shaft system are both mounted on the pedal support; the control motor-small gear shaft system is mainly formed by a control motor, a first transmission poking fork shaft, a second transmission poking fork shaft and a small gear; the first transmission poking fork shaft is fixedly mounted on an output shaft of the control motor; the first and second transmission poking fork shafts are coaxially connected by poking forks thereof; the poking forks of the first and second transmission poking fork shafts are set in a free rotating angle in the peripheral direction in advance; and the small gear on the control motor-small gear shaft system is in meshing transmission with a sector gear on the pedal rotary shaft system to realize the power transmission between the two shaft systems. The active feedback car accelerator pedal device can realize the man-machine bidirectional interactive function of information.
Description
technical field [0001] The invention belongs to the technical field of automobile driving assistance systems, in particular to an accelerator pedal mechanical device in the automobile field. Background technique [0002] The accelerator pedal, also known as the accelerator pedal, is a part of the fuel supply system of the car and is one of the key accessories of the car. The traditional cable type accelerator pedal is mainly composed of pedal bracket, accelerator pedal, accelerator cable, return spring, etc. The accelerator pedal is directly mechanically connected to the engine throttle through the accelerator cable. With the development of automotive electronic technology, electronic accelerator pedals are widely used in automobiles, and its structural components are mainly pedal brackets, accelerator pedals, angular displacement sensors, return springs, etc.; After the signal is collected and processed by the pedal control system, it is sent to the CAN bus network of the ...
