The invention discloses a control method for a vehicle motor, and the method comprises the steps: obtaining reference voltage information, and obtaining reference voltage information according to a predetermined first non-zero basic voltage vector corresponding to a target sector and two second non-zero basic voltage vectors corresponding to the first non-zero basic voltage vector; a reference voltage vector is generated to control vehicle motor operation. Therefore, according to the method and the device, the vehicle can generate the reference voltage vector according to the first non-zero basic voltage vector and the two second non-zero basic voltage vectors corresponding to the first non-zero basic voltage vector under the condition of acquiring the reference voltage vector parameter and the target sector, namely acquiring the reference voltage information; the zero vector can be replaced by the second non-zero basic voltage vector in the generation process of the reference voltage vector, so that the zero vector is prevented from being used, the amplitude of the common-mode voltage generated in the vector modulation process is reduced, and the performance of the vehicle motor in the advancing process is improved.

    本申请公开一种车辆电机的控制方法,所述方法包括:获取到参考电压信息,根据预先确定的与目标扇区相对应的第一非零基本电压矢量,及与第一非零基本电压矢量相对应的两个第二非零基本电压矢量,生成参考电压矢量以控制车辆电机运行。如此,本申请使得车辆可在获取参考电压矢量参数及目标扇区,也即获取到参考电压信息的情况下,根据第一非零基本电压矢量,及与第一非零基本电压矢量相对应的两个第二非零基本电压矢量,生成参考电压矢量,使得参考电压矢量的生成过程中,零矢量可由第二非零基本电压矢量替代,从而避免零矢量的使用,矢量调制过程中生成的共模电压的幅值得以降低,进而,行进过程中的车辆电机的性能得到提升。
