The invention relates to a torque control method and device for a vehicle, electronic equipment and a storage medium, and the method comprises the steps that driver demand torque, sliding recovery torque, crawling demand torque and ADAS function demand torque of the vehicle are obtained; based on the current working condition of the vehicle, the optimal demand torque is determined from the driver demand torque, the sliding recovery torque, the crawling demand torque and the ADAS function demand torque, and the whole vehicle demand total torque is obtained based on the optimal demand torque; and on the basis of a preset efficiency optimal distribution principle, front axle demand torque and rear axle demand torque are distributed according to the whole vehicle demand total torque and the dual-motor efficiency Map, low-pass filtering processing is conducted on the front axle demand torque and the rear axle demand torque, and front motor request torque and rear motor request torque are obtained. Therefore, the problem that the torque link structure of the whole vehicle is not stated in the related technology is solved, and the requirements for power, economy, smoothness and comfort of the whole vehicle are met.

    本申请涉及一种车辆的扭矩控制方法、装置、电子设备及存储介质,其中,方法包括:获取车辆的驾驶员需求扭矩、滑行回收扭矩、蠕行需求扭矩和高级驾驶辅助系统ADAS功能需求扭矩;基于车辆的当前工况,从驾驶员需求扭矩、滑行回收扭矩、蠕行需求扭矩和ADAS功能需求扭矩中确定最佳需求扭矩,并基于最佳需求扭矩得到整车需求总扭矩;以及基于预设的效率最优分配原则,根据整车需求总扭矩和双电机效率Map分配前轴需求扭矩和后轴需求扭矩,并分别对前轴需求扭矩和后轴需求扭矩进行低通滤波处理,得到前电机请求扭矩和后电机请求扭矩。由此,解决了相关技术未阐述整车的扭矩链路架构的问题,达到整车动力、经济、平顺性、舒适性要求。
