Technical field
The present invention relates to field of vehicle control more particularly to a kind of power supply redundancy methods of electronic control system.
Background technique
With the gradually development of Auto Electronic Controlled System, Full Vehicle System has all used electronically controlled mode.It is conventional
Electronic control system can be by the way of multichannel input power, to the different loads system power supply of internal system.When all the way or
When person's multichannel input power the reasons such as burns because of fuse and can not power to load system, the corresponding function of electronic control system is just
Failure.Therefore, entire electronic control system function when one or more input power disconnects in current vehicle control system is solved
The problem of failure, is just particularly important.
Summary of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of power supply redundancy method of electronic control system,
Increase power supply switch circuit inside the control system, by power supply switch circuit may be implemented all the way or multichannel input power lose
In the case where effect, whole system can guarantee to obtain complete power supply supply, solve one in current vehicle control system
When road or multichannel input power disconnect the problem of entire electronic control system disabler.
The present invention provides a kind of power supply redundancy method of electronic control system, and the control system includes connector, power supply
Switching circuit, power sense circuit, load one, load two, micro-control module and power module, to multichannel input power
The detection of multichannel input power state in electronic control system actively switches the input power of internal circuit, guarantees that system exists
Certain road power input still can obtain complete power input when failing.
Further improvement lies in that: the micro controller module detects the shape of multichannel input power by detection circuit in real time
State；When discovery has perhaps multichannel input power does not input all the way when i.e. fuse burn out or harness disconnect, microcontroller mould
Block opens switching circuit and enters emergency operating condition, and the power supply normally inputted is connected to the load one and load two of internal system, is protected
Card system function can continue to receive the control of micro controller module.
Further improvement lies in that: the micro controller module detects the shape of multichannel input power by detection circuit in real time
State；When detect certain all the way or multichannel input power fail after, the power supply normally inputted is connected to the load of internal system
One and load two enter emergency operating condition when, micro controller module is when system needs to be implemented powerful operating condition, by connector
Power source loads ability carries out power limit.
Further improvement lies in that: warning message is provided to driver when the micro controller module works.
Further improvement lies in that: the power supply module of the micro controller module is powered simultaneously by multichannel input power,
The failure of single channel or multichannel input power will not influence the work of micro controller module.
Further improvement lies in that: the switching circuit is turned on or off by being driven by microcontroller, and can be by big
The electronic component of electric current is constituted, can by MOSFET, relay or other can play the electronics member of switch high-power circuit
Device composition.
Scheme can solve after one or more failure in multichannel input power, the corresponding function of electronic control system
The problem of stopping working.It can be driven and turn on or off by microcontroller, can be made up of the electronic component of high current
Switching circuit be key point of the invention.
Micro controller module controls switching circuit, guarantees that electronic control system uses multichannel independent input in normal conditions
Power work, meet an urgent need operating condition under using input power all the way work.
Micro controller module detects multiple power supplies input, can be with alert when there is input power failure all the way.
The beneficial effects of the present invention are: system is to input power real-time detection, when being confirmed as external power supply input failure,
It can actively be switched on effective input power, guarantee that the function of system still may be implemented.System is able to detect that failure
Input power port, can be when realizing system normal function, load capacity by corresponding input power is to realizing function
Operating condition adjusts, and avoids input power circuit overloads.System is able to detect that the failure of any input power, and passes through alarm dress
It sets (such as instrument) and provides warning message to driver.
