Problems solved by technology

However, to detect whether the accelerator pedal is stuck through the pressure sensor, a pressure sensor needs to be added to the accelerator pedal, which will increase the manufacturing cost of the electric vehicle, and will also affect the structural design of the electric vehicle to a certain extent. The method of whether the accelerator pedal is stuck has a high cost and a difference in flexibility

Abstract

The application discloses a method for detecting stuck accelerator pedal and a vehicle controller, which relate to the technical field of electric vehicle control. The method of the present application includes: during the driving process of the target vehicle, when it is detected that the brake pedal is pressed first, and then the brake pedal is released, acquiring the current vehicle speed corresponding to the target vehicle, the acceleration pedal corresponding The current depressing depth and the historical depressing depth, wherein, the current depressing depth corresponding to the accelerator pedal is the depressing depth of the accelerator pedal at the current moment, and the historical depressing depth corresponding to the accelerator pedal is the depressing depth at the previous moment. Depressed depth of the accelerator pedal; determining whether the accelerator pedal is stuck according to the current vehicle speed, the current depressed depth and the historical depressed depth. This application is applicable to the process of detecting whether the accelerator pedal is stuck.

Description

technical field [0001] The application relates to the technical field of electric vehicle control, and in particular, to a method for detecting stuck accelerator pedal and a vehicle controller. Background technique [0002] With the continuous development of society and the continuous improvement of people's living standards, people's demand for automobiles is also increasing. Due to the shortage of energy and the increasingly serious environmental pollution problems caused by traditional automobiles, electric vehicles powered by electric energy are introduced as the times require. pregnancy. The process of driving an electric vehicle is generally as follows: the driver depresses the accelerator pedal, and the vehicle controller determines the required torque corresponding to the electric vehicle according to the corresponding depression depth of the accelerator pedal, and requests the motor to output the required torque to drive the electric vehicle. When driving, when the...
