A latch assembly for a motor vehicle having a primary power source is disclosed, comprising: a ratchet; a pawl for selectively engaging with the ratchet; a standby power supply; a motor for moving the pawl to disengage from the ratchet using power from the main power source or the backup power source; and a boost-buck converter connected to the main power source, the backup power source, and the motor. Where the main power source is available, the boost-buck converter operates in a buck mode to reduce a voltage level supplied from the main power source and charge the backup power source using the reduced voltage level. The boost-buck converter operates in a boost mode in an emergency condition to increase a voltage level supplied from the backup power supply and supply a boosted voltage to power the motor.
公开了一种用于具有主电源的机动车辆的闩锁组件,包括:棘轮;用于与棘轮选择性地啮合的棘爪;备用电源;用于使用来自主电源或备用电的电力来移动棘爪以与棘轮脱离的电动机;以及连接到主电源、备用电源和电动机的升压‑降压转换器。在主电源可用的情况下,升压‑降压转换器在降压模式下操作,以降低从主电源供应的电压电平并且使用降低的电压电平来对备用电源充电。升压‑降压转换器在紧急状况下在升压模式下操作,以增加从备用电源供应的电压电平并且供应经升压的电压以向电动机供电。
