The invention relates to the technical field of vehicles, in particular to a curve acceleration and deceleration torque control method and device, a vehicle and a storage medium, and the method comprises the steps that when the vehicle is in a curve working condition, the required total torque and the current total torque of a wheel end are recognized; calculating an actual torque difference value between the required total torque and the current total torque; the target descending slope of the actual torque difference value is obtained by looking up a table based on the total required torque, and the current descending slope of the actual torque difference value is corrected according to the target descending slope, so that the problems of head pushing and drifting caused by poor lateral attachment due to quick change of the torque in the early stage are avoided; the torque distribution proportion of the front and rear shafts and the inner and outer wheels is judged through the torque difference, and the drifting problem of an acceleration push head and an accelerator pedal is optimized through torque distribution. Therefore, the problems that in the related technology, head pushing and drifting of the vehicle cannot be considered when the vehicle accelerates and decelerates at the curve, the driving safety is reduced, and the driving experience of a user is affected are solved.

    本申请涉及车辆技术领域,特别涉及一种弯道加减速扭矩控制方法、装置、车辆及存储介质,其中,方法包括:在车辆处于弯道工况下,识别轮端的需求总扭矩和当前总扭矩;计算需求总扭矩和当前总扭矩之间的实际扭矩差值;基于需求总扭矩查表得到实际扭矩差值的目标下降斜率,根据目标下降斜率对实际扭矩差值的当前下降斜率进行修正,避免扭矩前期变化较快,引起侧向附着较差带来推头和甩尾的问题,并通过扭矩差判断前后轴和内外轮的扭矩分配比例,通过扭矩分配优化加速推头和丢加速踏板甩尾问题。由此,解决了相关技术中在车辆弯道加减速行驶时无法兼顾车辆的推头和甩尾问题,降低行车的安全性,影响用户驾驶体验等问题。
