The invention relates to a vehicle braking control method and device, a readable storage medium, a chip and a vehicle. The method comprises the steps that under the condition that automatic valet parking (AVP) is started, if an electronic stability program (ESP) of a vehicle body fails, the shaft speed of a power motor is obtained; whether the vehicle speed of the vehicle is larger than a preset first vehicle speed threshold value or not is determined according to the shaft speed of the power motor; when the vehicle speed of the vehicle is larger than the first vehicle speed threshold value, a backup braking controller controls hydraulic braking so as to apply regular braking force to the vehicle; and in the process of applying the regular braking force to the vehicle, parking braking is controlled according to the shaft speed of the power motor and the longitudinal acceleration of the vehicle. Therefore, under the condition that the ESP fails, the brake control of the vehicle can be realized by utilizing the backup brake controller without adding an additional wheel speed sensor, parts and wire harnesses are reduced, and the installation difficulty and cost of the vehicle are reduced.
本公开涉及一种车辆制动控制方法、装置、可读存储介质、芯片及车辆。该方法包括:在自动代客泊车AVP开启的情况下,若车身电子稳定系统ESP失效,则获取动力电机的轴速;根据所述动力电机的轴速确定所述车辆的车速是否大于预定的第一车速阈值;当所述车辆的车速大于所述第一车速阈值时,备份制动控制器控制进行液压制动,以向所述车辆施加规律性制动力;在向所述车辆施加规律性制动力的过程中,根据所述动力电机的轴速和所述车辆的纵向加速度控制进行驻车制动。这样,在ESP失效的情况下,利用备份制动控制器,不增加额外的轮速传感器,也能实现车辆的制动控制,减少了零件和线束,降低了车辆的安装难度和成本。
