Abstract

The invention discloses a method for an automobile VCU to analyze a torque of a pedal opening degree. The method comprises the following steps: when the pedal opening degree is verified to be 0%, entering a P-gear verification mode, pressing down an emergency stop button, continuously pressing down an ice and snow mode button for five times, and enabling two feet to leave the pedal; the ADC samples voltage values u1 reported by the two pedal sensors and collected by PIN angles, the voltage values u1 are converted into voltage values with the opening degree of 0% in a program, and the voltage values u1 are stored in the eerom; when the opening degree of the pedal is verified to be 0%, the verification mode is recorded as a P gear, an emergency stop button is pressed down for 10 s, an ice and snow mode button is pressed at least seven times continuously, and meanwhile a brake and an accelerator pedal are stepped down to the end; the ADC samples voltage values u2 reported by the two pedalsensors and collected by PIN angles, the voltage values u2 are converted into voltage values with the opening degree being 100% in a program, and the voltage values u2 are stored in the eerom; the initial state of an accelerator pedal and a brake pedal is verified, and the pedal opening analysis accuracy is improved; the full-opening state of the accelerator pedal and the brake pedal is verified,and the pedal analysis accuracy is improved.

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...
