The invention relates to a vehicle pedal signal reference value self-adaptive adjustment method and device and belongs to the technical field of new energy vehicle whole vehicle control. The pedal effectiveness information and the accelerator pedal opening information of a vehicle and the effectiveness information and the brake pedal opening information of a brake pedal are collected; the pedal validity information is the information for determining that the pedal is stepped down; a current running state of the vehicle is judged according to the pedal effectiveness information of the accelerator pedal, if the accelerator pedal is effective, the vehicle is in a driving state, and if the brake pedal is effective, the vehicle is in a braking state; if in the driving state, the acquired brake pedal opening degree information is used as a brake signal reference value; in the braking state, the collected accelerator pedal opening degree information serves as an acceleration signal reference value, and problems that signals are inaccurate and the reliability of the vehicle control process is low due to improper selection of pedal signal threshold values, mechanical clamping stagnation of pedals, temperature drift of parts and the like are solved.
本发明涉及一种车辆踏板信号基准值自适应调整方法及装置,属于新能源车整车控制技术领域,采集车辆的加速踏板的踏板有效性信息、加速踏板开度信息,制动踏板的有效性信息和制动踏板开度信息;踏板有效性信息为确定踏板被踩下的信息;根据加速踏板的踏板有效性信息判断车辆当前运行状态,如果加速踏板有效,则为驱动状态,如果制动踏板有效,则为制动状态;如果在驱动状态下,将采集的制动踏板开度信息作为制动信号基准值;如果在制动状态下,将采集的加速踏板开度信息作为加速信号基准值,解决了因踏板信号阈值选取不当以及踏板机械卡滞、零部件温漂等引起的信号不准确、车辆控制过程可靠性低的问题。
