The invention discloses a power supply gear switching method and device of an electric automobile, a vehicle control unit and a vehicle. The method comprises the steps: recognizing the gear switching intention of an electric vehicle; if the gear switching intention is the starting intention, determining a target power supply gear according to the gear switching intention; and on the basis of the target power supply gear, supplying power to the related parts of the whole vehicle corresponding to the target power supply gear, and awakening the related parts of the whole vehicle to perform power supply output. Therefore, the problems that in the prior art, the whole vehicle power supply gear switching function is completed through two controllers together, the whole vehicle power supply gear control logic is complex, and consequently some whole vehicle control system states and power supply gears are not matched are solved, the power supply gears are controlled through the VCU, PEPS is fused, the whole vehicle cost is reduced, the power supply gears of the whole vehicle can be switched more reasonably and conveniently, and the requirements for remote control function extension and safety of the whole vehicle can be met.

    本申请公开了一种电动汽车的电源挡位切换方法、装置、整车控制器及车辆,其中,方法包括:识别电动汽车的挡位切换意图;若挡位切换意图为启动意图,则根据挡位切换意图确定目标电源挡位;基于目标电源挡位为与目标电源挡位对应的整车相关部件供电,并唤醒整车相关部件,以进行供电输出。由此,解决了相关技术中通过两个控制器一起完成整车电源挡位切换功能,导致整车电源挡位控制逻辑的复杂性,从而造成一些整车控制系统状态和电源挡位不匹配的问题,通过VCU控制电源挡位,在融合PEPS降低整车成本的同时,使得整车电源挡位切换更合理、便捷,而且能够满足整车远程控制功能扩展和整车安全性要求。
