The invention discloses a self-locking circuit which comprises: a first end of a first switching device is connected with a first electrical node of the self-locking circuit, a second end of the first switching device is connected with a third end of the first switching device through a first load, a second end of the first switching device is connected with a second electrical node of the self-locking circuit, and a third end of the first switching device is connected with a third electrical node of the self-locking circuit through a second load and a first current limiting part; the first end of the second switching device is connected with a fourth electrical node of the self-locking circuit through a second current limiting piece, the second end is connected with a fifth electrical node of the self-locking circuit and is connected with the third end of the second switching device through a third load, and the third end of the second switching device is connected with a sixth electrical node of the self-locking circuit through a fourth load; the third current limiting piece is connected between a third electrical node and a fourth electrical node of the self-locking circuit; one end of the voltage stabilizing member is connected with the second electrical node, and the other end is connected between the second load and the first current limiting member. The invention further discloses a vehicle body controller with the self-locking circuit. The vehicle body controller can still keep driving current output when the BCM enters a dormant state, and has a better power-saving effect.
本发明公开了一种自锁电路包括:第一开关器件第一端连该自锁电路第一电气节点,第二端经第一负载连其第三端,第二端连该自锁电路第二电气节点,第三端经第二负载和第一限流件连该自锁电路第三电气节点;第二开关器件第一端经第二限流件连该自锁电路第四电气节点,第二端连该自锁电路第五电气节点并经第三负载连其第三端,其第三端经过经第四负载该自锁电路第六电气节点;第三限流件连在该自锁电路第三电气节点和第四电气节点之间;稳压件一端连第二电气节点,其另一端连在第二负载和第一限流件之间。本发明还公开了一种具有所述自锁电路的车身控制器。本发明的车身控制器能在BCM进入休眠状态仍能保持驱动电流输出,具有更好的节电效果。
