Description
Technical field
The utility model relates to field of power electronics, is specifically related to electric system under a kind of automobile controller time delay, is applicable to guarantee that data store intact.
Background technology
Vehicle control device before closing generally needs partial data to be saved in the data storage cell of controller, to call during start next time.Therefore after user's powered-down switch, controller can not power-off immediately, needs to make controller continue powered operation a period of time, thus ensures that data integrity is saved in controller storage unit.The method of general head it off uses relay or energy-storage travelling wave tube.
The principle of traditional relay control mode be treat that MCU has preserved data after, MCU controls to turn off main relay, thus reaches and postpone lower electric object, and the shortcoming of this mode is: first, uses relay to realize life-span of this function relatively short; Secondly, the control coil of main relay has storage battery power supply, when system power supply is unstable or there is larger interference (high power load), main relay misoperation may be caused, cause data not preserve, even cause the damage of MCU, be therefore easily subject to power supply disturbance.
