A Force Feedback Double-action Vehicle Safety Throttle Control System and Method

Abstract

The invention relates to a force feedback double-action automobile safety throttle control system and method, belonging to the technical field of auto parts equipment. It consists of accelerator pedal, accelerator pedal force sensor, accelerator pedal connecting rod, accelerator acceleration sensor, accelerator position sensor, accelerator pedal control unit, instrument panel signal light, cab buzzer, accelerator pedal return spring, and electromagnetic damper. By collecting the input voltage signals of the accelerator pedal force sensor, accelerator acceleration sensor, and accelerator position sensor, combined with the internal logic program group to judge the driver's operation mode, the operation mode is displayed in different colors through the dashboard signal light and the cab buzzer. Signal lights and buzzers of different frequencies give feedback to the driver. The operating state of the accelerator is combined with the force feedback of the accelerator pedal and the sound and light signals in the cab, so that the driver can accurately perceive the current accelerator control state without leaving the road, making the driving of the vehicle safer.

Description

technical field [0001] The invention relates to a force feedback double-action automobile safety accelerator control system and method, belonging to the technical field of auto parts equipment. Background technique [0002] Because the traditional accelerator pedal is pressed down quickly to realize the rapid acceleration function of the car, especially on vehicles with large displacement and good acceleration performance, the speed of the car in the state of rapid acceleration soars too fast, which makes driving The response time for effective control of the speed of the vehicle is short, which is not conducive to the safe driving of the vehicle. If the driver is not familiar with the performance of the car, or the driving skills are not skilled, in the event of an emergency, the driver may mistake the accelerator for the brake and step on it quickly in a state of panic, so that the operation that should be braking becomes instead Rapid acceleration, this kind of misoperat...

Problems solved by technology

[0004] At present, there have been many studies on the mechanical accelerator pedal or accelerator brake linkage system. These studies have shown that for the early mechanical throttle valve (gasoline vehicles) or the high-pressure oil pump fuel supply plunger rack (diesel vehicles) to control the fuel injection quantity The vehicles can play a corresponding control role, but it is not applicable to the vehicles with electronically controlled fuel injection systems commonly used at present (equipped with engines that rely on electronic accelerator pedals and ECUs for fuel quantity control), these vehicles are equipped with electronic pedals, Send the corresponding fuel supply control signal to the engine ECU through the pedal
