(note: the switch state of vehicle mounted electrical apparatus cannot influence to travel the vehicle mounted electrical apparatus such as air-conditioning, ptc heater and vehicle-mounted service system at this time
In vehicle safety) do not shut down or open, Vehicular accumulator cell electricity can be consumed, may cause low tension battery to turn to
Motor electricity shortage or abnormal electrical power supply, steering motor can not work normally, and be unable to ensure vehicle safety.
Summary of the invention
The purpose of the present invention is to provide a kind of double source steering boost system control method and systems, are configuring for solving
On the automobile of double source steering boost system, when main power source part when something goes wrong, stand-by power supply deficiency cause steering motor without
The problem of method works normally.
In order to solve the above technical problems, steps are as follows the present invention provides a kind of double source steering boost system control method:
When detecting main power supply system failure, emergency electric system power supply is converted to；The main power supply system failure packet
Include main electricity, route and equipment fault；
It sends and instructs to vehicle mounted electrical apparatus, force vehicle mounted electrical apparatus power-off or limitation vehicle mounted electrical apparatus starting.
The present invention also provides a kind of double source steering boost system control system, including entire car controller, the vehicle control
Device processed includes processor and memory, and the processor executes the instruction of storage in the memory to realize following method:
When detecting main power supply system failure, emergency electric system power supply is converted to；The main power supply system failure packet
Include main electricity, route and equipment fault；
It sends and instructs to vehicle mounted electrical apparatus, force vehicle mounted electrical apparatus power-off or limitation vehicle mounted electrical apparatus starting.
Beneficial effects of the present invention:
When main power supply system breaks down, to guarantee vehicle safety, steering controller enables reserve battery power supply, together
When, entire car controller acquires malfunction instruction, sends forced stoppage instruction to vehicle mounted electrical apparatus, forces vehicle mounted electrical apparatus power-off or limit
Vehicle mounted electrical apparatus starting processed.Thus in the case where Vehicular accumulator cell is powered to steering motor, guarantee steering motor work 30-
60s avoids accident, and driver is promoted to operate vehicle safety parking maintenance.
As the further improvement of method and system, described instruction is CAN message and/or low and high level signal.Vehicle control
It is communicated between device processed and vehicle mounted electrical apparatus by the bimodulus connection type of rigid line and CAN network, when main power supply system breaks down,
If one of communication mode failure, another kind can still receive instruction, caused by avoiding because of route or CAN network reason
Communication failure guarantees that the electricity of emergency electric system is completely used for supply steering motor, guarantees the operability of Vehicular turn, protect
The safety of vehicle in traveling is demonstrate,proved.
As the further improvement of method and system, the main electricity is high voltage power battery.
As the further improvement of method and system, the emergency electric system is low-voltage power supply system.
As the further improvement of method and system, the vehicle mounted electrical apparatus is air-conditioning and/or ptc heater.
