The invention provides a torque control method and device and a vehicle, and relates to the technical field of intelligent driving. According to the method, the wheels about to pass through the sudden change site are predicted, and torque transfer between different wheels is completed before the wheels pass through the sudden change site, so that the braking force of the whole vehicle is prevented from being reduced while the slip rate is reduced. The method comprises the following steps: acquiring detection data; according to the detection data, it is predicted that the first wheel arrives at a first site after the first time period, and the landform features of the first site meet preset conditions. In the first time period, the current first torque of the first wheel is adjusted to be second torque, the current third torque of the second wheel is adjusted to be fourth torque, and the first absolute value of the difference value between the first torque and the second torque is equal to the second absolute value of the difference value between the third torque and the fourth torque; the first wheel and the second wheel correspond to different actuators.

    本申请提供扭矩控制方法、装置及车辆,涉及智能驾驶技术领域。本申请通过预测即将经过突变地点的车轮,在该车轮经过突变地点前完成不同车轮间的扭矩转移,从而在降低滑移率的同时避免整车制动力下降。该方法包括:获取检测数据。根据该检测数据,预测第一车轮在第一时间段后到达第一地点,该第一地点的地貌特征满足预设条件。在第一时间段内,将当前第一车轮的第一扭矩调整为第二扭矩,将当前第二车轮的第三扭矩调整为第四扭矩,其中第一扭矩和第二扭矩之间的差值的第一绝对值等于第三扭矩和第四扭矩之间的差值的第二绝对值,第一车轮和第二车轮对应于不同的执行器。
