The invention discloses a vehicle low-pressure system and a vehicle. The vehicle comprises a cabin area and a passenger compartment area, the system comprises a low-voltage power supply and an active protection module which are arranged in the passenger compartment area, and the low-voltage power supply is used for supplying power to a first low-voltage load of the passenger compartment area and supplying power to a second low-voltage load of the cabin area through the active protection module; and the active protection module is used for disconnecting a power supply loop between the low-voltage power supply and the DC-DC voltage converter in response to a collision protection signal generated when the vehicle collides. Therefore, it can be guaranteed that the low-voltage power source is not damaged after the vehicle collides, it can be guaranteed that the low-voltage power source can continuously supply power to the first low-voltage load in the passenger compartment area, and the low-voltage safety requirement is met.
本发明公开了一种车辆低压系统及车辆。其中,车辆包括机舱区域和乘员舱区域,系统包括设于乘员舱区域的低压电源和主动保护模块,低压电源用于给乘员舱区域的第一低压负载供电,并通过主动保护模块给机舱区域的第二低压负载供电;主动保护模块用于响应于车辆发生碰撞时产生的碰撞保护信号,断开低压电源与直流‑直流电压转换器之间的供电回路的连接。由此,不仅能够保证低压电源在车辆发生碰撞后不被损坏,而且能够保证低压电源能持续为乘员舱区域的第一低压负载供电,满足低压安全要求。
