The invention provides a vehicle torque processing method, device and equipment. The method comprises the following steps: determining a required torque of a driver based on a vehicle driving state and an accelerator pedal opening degree; in combination with torque boundaries corresponding to pre-calibrated different torque demand types, determining a target torque demand type corresponding to the demand torque, and the torque demand type is used for reflecting the demand tendency of a driver for economical efficiency and dynamic property; and distributing torque for each motor of the vehicle based on a torque distribution rule corresponding to the target torque demand type. Therefore, the demand torque of the driver can be intelligently judged, the torque distribution scheme can be quickly formulated in combination with the pre-calibrated torque boundaries of different torque demand types, and the situation that the VCU needs to continuously calculate the system efficiency is avoided, so that the working efficiency of the VCU is effectively improved.

    本申请提供一种车辆扭矩处理方法、装置及设备。方法包括:基于车辆行驶状态和加速踏板开度,确定驾驶员的需求扭矩;结合预标定的不同扭矩需求类型对应的扭矩边界,确定所述需求扭矩对应的目标扭矩需求类型,扭矩需求类型用于反映驾驶员对经济性和动力性的需求倾向;基于所述目标扭矩需求类型对应的扭矩分配规则,为车辆的各电机分配扭矩。由此可知,本申请可智能判断驾驶员的需求扭矩,而且结合预先标定的不同扭矩需求类型的扭矩边界,可快速制定扭矩分配方案,避免需要整车控制器VCU对系统效率持续进行计算,从而有效提高VCU的工作效率。
