Provided is power supply during vehicle startup. A system includes a virtual-driver module, a DC/DC converter electrically coupled to the virtual-driver module, a low-voltage battery electrically coupled to the virtual-driver module, a high-voltage battery electrically coupled to the DC/DC converter, and a computer communicatively coupled to the DC/DC converter. The computer is programmed to, in response to a request to start a vehicle including the virtual-driver module in a manual mode, the vehicle being in an off state at the time of the request, set a setpoint of the DC/DC converter at a first voltage; then perform at least one pre-drive test on the vehicle; and then set the setpoint of the DC/DC converter at a second voltage lower than the first voltage.
本公开提供了“车辆起动期间的电力供应”。一种系统包括虚拟驾驶员模块;DC/DC转换器,所述DC/DC转换器电耦接到所述虚拟驾驶员模块;低压电池,所述低压电池电耦接到所述虚拟驾驶员模块;高压电池,所述高压电池电耦接到所述DC/DC转换器;以及计算机,所述计算机可通信地耦接到所述DC/DC转换器。所述计算机被编程为响应于在手动模式下起动包括所述虚拟驾驶员模块的车辆的请求,所述车辆在所述请求时处于关闭状态,将所述DC/DC转换器的设定点设定为第一电压;然后对所述车辆执行至少一个预驾驶测试;并且然后将所述DC/DC转换器的所述设定点设定为低于所述第一电压的第二电压。
