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

The invention discloses a method for detecting clamping stagnation of an accelerator pedal and a vehicle control unit, and relates to the technical field of electric vehicle control. The method comprises the steps that in the running process of a target vehicle, when it is firstly detected that a brake pedal is stepped down and then it is detected that the brake pedal is loosened, the current vehicle speed corresponding to the target vehicle, the current stepping depth corresponding to the accelerator pedal and the historical stepping depth are obtained, wherein the current stepping depth corresponding to the accelerator pedal is the stepping depth of the accelerator pedal at the current moment, and the historical treading depth corresponding to the accelerator pedal is the stepping depthof the accelerator pedal at the previous moment; and according to the current vehicle speed, the current stepping depth and the historical stepping depth, whether the accelerator pedal suffers from clamping stagnation or not is determined. The method is suitable for the process of detecting whether the accelerator pedal suffers from clamping stagnation or not.
Description
technical field [0001] The present application relates to the technical field of electric vehicle control, in particular to a method for detecting stuck accelerator pedal and a vehicle controller. Background technique [0002] With the continuous development of society, people's living standards continue to improve, and people's demand for cars is also increasing. Due to energy shortages and environmental pollution caused by traditional cars are becoming more and more serious, electric vehicles powered by electric energy have emerged as the times require. pregnancy. The driving process of the driver driving the electric vehicle is generally as follows: the driver steps on the accelerator pedal, the vehicle controller determines the required torque corresponding to the electric vehicle according to the corresponding stepping depth of the accelerator pedal, and requests the motor to output the required torque, thereby driving the electric vehicle When driving, when the driver...
