The invention discloses a vehicle torque zero-crossing control method, device and equipment and a storage medium, and relates to the technical field of vehicles. The method comprises the steps that in response to a calibration instruction, the EPB state of a target vehicle is obtained; if the EPB state of the target vehicle is a clamping state, the target vehicle is controlled to be in a torque zero-crossing interval, torque rising or torque falling is conducted according to a preset gradient, and a target gap of a transmission system of the target vehicle is determined through a rotary transformer sensor; determining a target torque zero-crossing gradient parameter corresponding to the target gap according to a pre-configured corresponding relationship between the gap and the torque zero-crossing gradient parameter and the target gap; the torque zero-crossing gradient parameter of the target vehicle is modified from the historical torque zero-crossing gradient parameter to the target torque zero-crossing gradient parameter; and controlling the target vehicle to perform torque zero-crossing processing according to the target torque zero-crossing gradient parameter. According to the method, the knocking probability of the transmission system of the vehicle can be reduced, and the comfort and driving experience of the vehicle during torque zero-crossing are improved.

    本申请公开了一种车辆扭矩过零控制方法、装置、设备及存储介质,涉及车辆技术领域,该方法包括:响应于标定指令,获取目标车辆的EPB状态;若目标车辆的EPB状态为夹紧状态,控制目标车辆在扭矩过零区间,按照预设梯度进行升扭矩或降扭矩,通过旋变传感器确定目标车辆的传动系统的目标间隙;根据预先配置的间隙与扭矩过零梯度参数的对应关系以及目标间隙,确定目标间隙对应的目标扭矩过零梯度参数;将目标车辆的扭矩过零梯度参数由历史扭矩过零梯度参数修改为目标扭矩过零梯度参数;根据目标扭矩过零梯度参数,控制目标车辆进行扭矩过零处理。该方法能够降低车辆的传动系统出现敲击的概率,提升车辆在扭矩过零时的舒适性和驾驶体验。
