摘　　要：在汽车自动启停系统中,起动机工作时12 V系统的铅酸起动电池电压可能降至6.0 V或更低,从而造成汽车电器系统的不稳定工作,甚至可能造成系统的重启动或损坏;使整车的舒适性和可靠性降低。为了使电器设备在小于6.0 V的供电条件下,保持主要电路模块的稳定和可靠工作,本文设计了三种汽车电器设备电源系统方案,提出部分参考应用实例,有效的解决了汽车电器设备在发动机起动过程中工作电压不稳定的问题。In the automotive automatic start/stop system, lead-acid starter battery voltage 12V system might work down to 6.0V or lower, resulting in an unstable job automotive electrical systems, and even cause the system to restart and damage;making the car comfort and reliability. In order to make the electrical equipment is less than 6.0V supply conditions remain stable and reliable operation of the main system, This paper designed three automotive electrical equipment and power systems solutions part of the reference application examples, effective solution to the automotive systems of electrical equipment in the engine during start voltage instability.
