The invention provides a vehicle torque zero-crossing control method and device, a vehicle and a storage medium, and relates to the technical field of vehicles, the method comprises the steps of obtaining vehicle driving data, determining whether a torque zero-crossing demand exists or not according to the vehicle driving data, generating a torque zero-crossing request if the torque zero-crossing demand exists, and responding to the torque zero-crossing request, and determining an initial driving mode corresponding to the initial torque and a current driving mode corresponding to the target torque, determining a target torque gradient table according to the driving modes, and performing torque zero-crossing control based on the target torque gradient table. As different torque gradients are needed in different driving modes, the initial driving mode and the current driving mode corresponding to zero-crossing torque can be judged, and different torque gradient tables are selected as target torque gradient tables based on judgment results. According to the torque zero-crossing control method, the requirements of torque zero-crossing control in different driving modes are considered, and the effects of reducing torque zero-crossing impact and improving driving stability can be achieved.

    本申请提供一种车辆扭矩过零控制方法、装置、车辆以及存储介质,涉及车辆技术领域,该方法通过获取车辆行驶数据,并根据车辆行驶数据确定是否存在扭矩过零需求,若存在扭矩过零需求,则生成扭矩过零请求,响应于扭矩过零请求,确定初始扭矩对应的初始驾驶模式,和目标扭矩对应的当前驾驶模式,根据驾驶模式确定目标扭矩梯度表,并基于目标扭矩梯度表进行扭矩过零控制。由于不同驾驶模式下需要的扭矩梯度不同,可以对扭矩过零时对应的初始驾驶模式和当前驾驶模式进行判断,并基于判断结果选择不同的扭矩梯度表为目标扭矩梯度表。该扭矩过零控制方法考虑了不同驾驶模式下扭矩过零控制的需求,可以达到减小扭矩过零冲击,提高驾驶平稳性的效果。
