The invention relates to the technical field of automobile chassis control, and discloses a control method and system for a vehicle to pass through a protruding obstacle road surface, the vehicle and a medium. The method comprises the steps that the energy recovery intensity of the vehicle and the deceleration of a driving shaft are obtained; under the condition that the energy recovery intensity is strong energy recovery, if the DTC mode of the vehicle is activated, determining a target coefficient based on the deceleration, and determining a first target torque based on the target coefficient and the initial torque; the initial torque represents the output torque of the power system when the DTC mode is activated; the target coefficient is positively correlated with the deceleration, and the target coefficient is less than 1 and greater than 0; and updating the output torque of the power system based on the first target torque so as to control the vehicle to run. Therefore, under the condition that the energy recovery intensity of the vehicle is very high, even if the DTC mode is activated, a driver cannot feel the movement feeling generated by the sudden change of the torque, so that the driving experience of the driver can be improved.
本申请涉及汽车底盘控制技术领域,公开一种车辆通过凸起障碍物路面的控制方法、系统、车辆及介质。方法包括获取车辆的能量回收强度和驱动轴的减速度;在能量回收强度为强能量回收的情况下,若激活车辆的DTC模式,则基于减速度确定目标系数,并基于目标系数和初始扭矩确定第一目标扭矩;初始扭矩表征激活DTC模式时,动力系统的输出扭矩;目标系数与减速度成正相关,目标系数小于1且大于0;基于第一目标扭矩更新所述动力系统的输出扭矩,以控制车辆行驶。这样,在车辆的能量回收强度很大的情况下,即使激活DTC模式,也不会让驾驶员感受到由于扭矩突变而产生的窜动感,以能够提高驾驶员的驾驶体验。
