The invention provides an electric vehicle mode control method and system, a computer and a readable storage medium, and the method comprises the steps: judging whether a current whole vehicle meets a first preset condition or not when a vehicle starting request is received; if it is judged that the current whole vehicle meets the first preset condition, a power-on loop of the current whole vehicle is detected, and a whole vehicle power-on request signal is sent to a BMS through a bus; a main negative relay and a pre-charging relay are attracted through a BMS, and whether the current whole vehicle meets a second preset condition or not is detected; if it is judged that the current whole vehicle meets the second preset condition, the main positive relay and the main negative relay are attracted through the BMS, the pre-charging relay is disconnected, and the DCDC is controlled to start working; and when the DCDC completes high-low voltage conversion, receiving an output state signal fed back by the DCDC, and adjusting the current state of the whole vehicle to be ON. In this way, the power-on process of the whole vehicle can be simply and rapidly completed, meanwhile, the operation logic is simple, and the load rate of the whole vehicle controller is greatly reduced.
本发明提供了一种电动汽车模式控制方法、系统、计算机及可读存储介质,该方法包括当接收到车辆启动请求时,判断当前整车是否满足第一预设条件;若判断到当前整车满足第一预设条件,检测当前整车的上电回路,并通过总线向BMS发送整车上电请求信号;通过BMS吸合主负继电器以及预充继电器,且检测当前整车是否满足第二预设条件;若判断到当前整车满足第二预设条件,通过BMS吸合主正继电器以及主负继电器、断开预充继电器,并控制DCDC开始工作;当DCDC完成高低压转换时,接述DCDC反馈的输出状态信号,并将当前整车的状态调整为ON。通过上述方式能够简单快速的完成整车的上电过程,同时操作逻辑简单,大幅降低了整车控制器的负荷率。
