Abstract

The invention discloses a method for an automobile VCU to analyze the torque of the pedal opening. When the pedal opening is verified to be 0%, the verification mode is entered into the P gear, and the emergency stop button is pressed continuously for 5 times. The foot leaves the pedal; the voltage value u1 reported by the two pedal sensors collected by the ADC sampling PIN angle is converted into an opening of 0% in the program, and this value is stored in eerom; When it is 0%, it is included in the verification mode as P gear, press the emergency stop button for 10 seconds and press the ice and snow mode button for at least 7 times, and step on the brake and accelerator pedals to the end at the same time; the two pedal sensors collected by the ADC sampling PIN angle report The voltage value u2 is converted into 100% opening in the program and stored in eerom; the initial state of the accelerator pedal brake pedal is verified, and the accuracy of the pedal opening analysis is increased; the accelerator pedal is verified The brake pedal is fully opened to increase the accuracy of pedal analysis.

Description

technical field [0001] The invention relates to a new energy vehicle VCU, in particular to a method for the vehicle VCU to analyze the torque of the pedal opening. Background technique [0002] At this stage, the vehicle controller as the brain of the vehicle and a controller that interacts between the driver and the vehicle plays an irreplaceable role in the vehicle controller, especially in collecting the opening of the accelerator pedal and brake pedal as a vehicle controller. The accuracy aspect of the torque analysis input is particularly important. Acceleration pedals and brake pedals currently on the market use sensors to collect analog opening and convert voltage values, and there may be deviations in the sampling range due to differences in pedal installation and sensors. [0003] (1) The displayed initial position is inaccurate; [0004] (2) The termination position is inaccurate; [0005] (3) In terms of model verification, the pedal opening and vehicle speed a...
