The invention relates to the technical field of vehicles, in particular to a data calibration method and device for vehicle motor auxiliary heating, a vehicle and a medium, and the method comprises the steps that whether the vehicle is in a target motor auxiliary heating working condition or not and is in a torque working mode or not is detected; when it is detected that the vehicle is in the target motor auxiliary heating working condition and in the torque working mode, the target driving heating power and the target torque of the vehicle are obtained; and matching corresponding first direct-axis current and first quadrature-axis current in a pre-constructed first database based on the target driving heating power and the target torque so as to perform motor auxiliary heating on the vehicle according to the first direct-axis current and the first quadrature-axis current. Therefore, the problems that in the related technology, when a water pump is driven for heating, extra electric energy is consumed, the water pump is only suitable for specific driving working conditions, the applicability of auxiliary heating of the motor is low, the overall energy efficiency of the vehicle is reduced, and the applicability and reliability of auxiliary heating of the vehicle motor are reduced are solved.
本申请涉及车辆技术领域,特别涉及一种车辆电机辅助加热的数据标定方法、装置、车辆及介质,其中,方法包括:检测车辆是否处于目标电机辅助加热工况,并且是否处于转矩工作模式;在检测到车辆处于目标电机辅助加热工况,且处于转矩工作模式的情况下,获取车辆的目标行车加热功率和目标转矩;基于目标行车加热功率和目标转矩在预先构建的第一数据库中匹配对应的第一直轴电流和第一交轴电流,以根据第一直轴电流和第一交轴电流对车辆进行电机辅助加热。由此,解决了相关技术中驱动水泵进行加热会额外消耗电能,仅适应于特定的行车工况,导致电机辅助加热的适用性较低,造成车辆的整体能效下降,降低了车辆电机辅助加热的适用性和可靠性等问题。
