Abstract
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.
