Throttle control device, system and method

Abstract

The invention provides a throttle control device, system and method, wherein the device includes a controllable channel selection module, a signal conversion module, a microprocessor and a pseudo-throttle signal simulation module; Connection with the electronic accelerator pedal or pseudo-accelerator signal analog module; the signal conversion module collects the accelerator signal of the electronic accelerator pedal through the controllable channel selection module, converts the accelerator signal into a digital signal and sends it to the microprocessor; the microprocessor processes the digital signal Get the pseudo-throttle digital signal; the pseudo-throttle signal analog module converts the pseudo-throttle digital signal into an analog signal to obtain a pseudo-throttle signal; the controllable channel selection module chooses to use the throttle signal or the pseudo-throttle signal to adjust the throttle controller of the engine according to user needs to control The gas pedal of the car. The invention realizes the automatic control of the accelerator of the automobile through the pseudo-accelerator signal, and provides convenience for the accelerator control of the aftermarket or test reformed vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile automatic control, in particular to an accelerator control device, system and method. Background technique [0002] With the development of electrification and intelligent technology, the role of drive-by-wire technology is becoming more and more important, such as adaptive cruise control (Adaptive Cruise Control, ACC), automatic driving and other intelligent driving technologies need to realize the automatic control of the car accelerator. control. [0003] The existing drive-by-wire systems are all aimed at the pre-installation market of automobiles, and it is difficult to modify vehicles for the after-installation market or test; automatic driving uses on-board sensors to realize the collection of internal and external information, on the premise of little or no driver intervention To realize the automatic control of the vehicle, the existing electronic throttle control system generally res...

AI Technical Summary

Problems solved by technology

For the pre-installation market, it is easy to coordinate the throttle supplier and the engine supplier, and get the exact communication protocol to control the engine throttle, but for the after-installation market or test and rebuilt vehicles, it is difficult to achieve
