The present disclosure provides "motorized vehicle low voltage (LV) bus voltage control". An electrically powered vehicle includes a traction battery coupled to an electric machine providing a propulsive force; an auxiliary battery; a voltage converter coupled to the traction battery and configured to convert the traction battery voltage to an auxiliary battery voltage; and a controller programmed to control the voltage converter to provide a non-oscillating voltage above a first voltage threshold or an oscillating voltage having a peak below the first voltage threshold based on a vehicle start signal and a vehicle brake pedal position signal. The controller may control the voltage converter to provide the non-oscillating voltage in response to the vehicle launch signal received when the brake pedal position signal indicates a released brake pedal, and control the voltage converter to provide the oscillating voltage in response to a vehicle launch signal received when the brake pedal position signal indicates a depressed brake pedal.
本公开提供了“电动化车辆低压(LV)总线电压控制”。一种电动化车辆包括:牵引电池,所述牵引电池联接到提供推进力的电机;辅助电池;电压转换器,所述电压转换器联接到牵引电池并且被配置成将牵引电池电压转换为辅助电池电压;以及控制器,所述控制器被编程以基于车辆起动信号和车辆制动踏板位置信号而控制所述电压转换器以提供高于第一电压阈值的非振荡电压或峰值低于第一电压阈值的振荡电压。所述控制器可响应于在所述制动踏板位置信号指示释放的制动踏板时接收的所述车辆起动信号而控制所述电压转换器以提供所述非振荡电压,并且响应于在所述制动踏板位置信号指示踩下的制动踏板时接收的车辆起动信号而控制所述电压转换器以提供所述振荡电压。
