The invention provides a vehicle torque control method and device based on a vehicle running road surface. The method comprises the steps of obtaining a target image of a target vehicle driving road surface at the current moment; determining a target category of a road surface on which the target vehicle runs at the current moment based on the target image, and determining a torque variation amplitude and a torque distribution ratio corresponding to the target category; acquiring a control torque sequence of the target vehicle at multiple moments before the current moment and vehicle feedback information corresponding to the control torque sequence; according to the control torque sequence and the vehicle feedback information, the torque change trend of the target vehicle is judged; and based on the torque change amplitude, the torque change trend and the last control torque in the control torque sequence, the target control torque of the target vehicle at the current moment is predicted, and the target vehicle is controlled at the current moment according to the target control torque and the torque distribution ratio. By the adoption of the technical means, the problems that in vehicle torque control in the prior art, due to the fact that the vehicle running road surface is not considered, power of the vehicle is insufficient, and the vehicle shakes and slips easily are solved.
本公开提供了一种基于车辆行驶路面的车辆扭矩控制方法及装置。该方法包括:获取当前时刻目标车辆行驶路面的目标图像;基于目标图像确定当前时刻下目标车辆行驶路面的目标类别,并确定目标类别对应的扭矩变化幅度和扭矩分配比;获取当前时刻之前多个时刻目标车辆的控制扭矩序列和控制扭矩序列对应的车辆反馈信息;依据控制扭矩序列以及车辆反馈信息,判断目标车辆的扭矩变化趋势;基于所述扭矩变化幅度、所述扭矩变化趋势和所述控制扭矩序列中最后一个控制扭矩,预测当前时刻所述目标车辆的目标控制扭矩,依据目标控制扭矩和扭矩分配比在当前时刻控制目标车辆。采用上述技术手段,解决现有技术中车辆扭矩控制由于没有考虑车辆行驶路面,导致车辆容易出现动力不足以及车辆抖动和打滑等问题。
