Abstract
一种车辆踏板开度的控制方法、系统、设备和介质,用于控制踏板开度以使车辆按照预设加速度运行,方法包括:S1,将踏板开度分为M段,并计算当前车速下该M段踏板开度对应的M个加速度;S2,获取预设加速度,根据M段踏板开度、M个加速度和预设加速度计算该预设加速度对应的第一踏板开度;S3,采集实际加速度,根据实际加速度与预设加速度之间的差值对第一踏板开度进行补偿,得到第二踏板开度;S4,根据预设规则控制踏板开度,使得该踏板开度等于第二踏板开度。基于车速、加速度和踏板开度的关系计算,扩展了控制方法的适用性,并基于实际加速度进行PID调节,提升了控制性能,并对踏板开度进行滤波处理,提升了整车的驾驶性能。
A method, system, device and medium for controlling a pedal opening degree of a vehicle, which are used to control the pedal opening degree to make the vehicle run according to a preset acceleration, the method comprising: S1, dividing the pedal opening degree into M sections, and calculating the current vehicle speed M accelerations corresponding to the pedal openings of the M segments; S2, obtaining a preset acceleration, and calculating the first pedal opening corresponding to the preset acceleration according to the pedal openings of the M segments, the M accelerations and the preset acceleration; S3, collecting the actual pedal opening Acceleration: Compensate the first pedal opening degree according to the difference between the actual acceleration and the preset acceleration to obtain the second pedal opening degree; S4, control the pedal opening degree according to the preset rule, so that the pedal opening degree is equal to the second pedal opening opening. Based on the calculation of the relationship between vehicle speed, acceleration and pedal opening, the applicability of the control method is expanded, and PID adjustment is performed based on the actual acceleration to improve the control performance, and the pedal opening is filtered to improve the driving performance of the vehicle.
