Main power control module 3, a kind of situation is, when having legal key, control automobile power source is by " shut " mode" OFF entering part powering mode ACC or enter full car powering mode ON by energize portions Mode A CC or enter " shut " mode" OFF by full car powering mode ON.Another kind of situation is, when automatic car stopping is being stepped on brake pedal or manually keeping off a car when stepping on clutch pedal, control automobile power source and enter engine start Mode S TART by " shut " mode" OFF or enter engine start Mode S TART by energize portions Mode A CC or enter engine start Mode S TART by full car powering mode ON.
Power starting circuit 2, a road direction main power control module PDU sends trigger pip; Another road direction keyless systems PEPS sends trigger pip.
Keyless systems 1, for when power starting circuit breaks down, substitute electric power main control module PDU works.
Power starting circuit, as shown in Figure 2, comprise resistance R1, R2, R3, R4 and double-pole single throw S1, wherein, resistance R1 one end connects A8 end (i.e. start/stop switch, switching signal pin) of PDU, the upper end fixed contact of double-pole single throw S1 successively, the upper end moving contact of the other end of resistance R1 contact resistance R2 one end, double-pole single throw S1 successively, the resistance R2 other end connects A11 end (i.e. start/stop end, inner ground pin) of PDU; One end of resistance R3 connects M1.20 end (the i.e. start/stop switch of PEPS, switching signal pin), the other end of resistance R3 connects the lower end fixed contact of double-pole single throw S1 and one end of resistance R4, double-pole single throw S1 lower end moving contact is connected with the other end of resistance R4, and ground connection.

Embodiment 2:
The startup button redundancy control method adopted in the present embodiment, its flow process as shown in Figure 3, the basis of embodiment 1 shown device is implemented.
Power starting circuit sends trigger pip to PDU and PEPS simultaneously, the voltage signal that the voltage signal that PDU collects and PEPS collect compares, if identical, then control automobile power source by main power control module to start, otherwise, send trigger pip to PDU by keyless systems by bus, control automobile power source and start.
For Fig. 2, resistance R1, R2, R3 and R4 are the resistance of similar resistance.
When double-pole single throw S1 disconnects, in power supply governor circuit, resistance R1 and resistance R2 connects, the switching signal that PDU collects for after R1, R2 series connection the magnitude of voltage that divides.In Redundant Control loop, resistance R3 and resistance R4 connects, the switching signal that PEPS collects for after R3 and R4 series connection the magnitude of voltage that divides.
When double-pole single throw S1 UNICOM, in power supply governor circuit, resistance R1 is fallen by double-pole single throw S1 short circuit, PDU the switching signal of adopting be resistance R2 both end voltage value.In Redundant Control loop, resistance R4 is fallen by double-pole single throw S1 short circuit, and the switching signal that PEPS collects is R3 both end voltage value.
If when there is inner adhesion in double-pole single throw S1 upper end fixed contact and upper end moving contact, then the upper end fixed contact of double-pole single throw S1 and upper end moving contact will be in connected state for a long time, so, for Energy control major loop, PDU is within certain sampling time, and the voltage always for resistance R2 two ends does not change by the switching signal collected.And for Redundant Control loop, when double-pole single throw S1 disconnects, lower end fixed contact and the lower end moving contact of double-pole single throw S1 disconnect, PEPS collect by be after resistance R3 resistance R4 connects the magnitude of voltage that divides, relatively, the two is obviously different, now, the switching signal collected is sent to PDU by by CAN by PEPES, and PDU carries out electric source modes control according to normal power mode steering logic.
If the line generation open circuit of double-pole single throw S1 and the PDU in main power control loop, then PDU will be the voltage value signal without R1, R2 dividing potential drop by the magnitude of voltage obtained of sampling completely, then according to this outlier, PDU can judge that open circuit fault occurs in main power control loop.Now, the switching signal collected is sent to PDU by by CAN by PEPES, and PDU carries out electric source modes control according to normal power mode steering logic.
When double-pole single throw S1 is closed, if there is upper end moving contact in double-pole single throw S1 or upper end stationary contact damages fault, then on double-pole single throw S1, terminal contacts and lower terminal contacts cannot close, so, for Energy control major loop, PDU within certain sampling time, the switching signal collected by always the voltage that divides by resistance R1 and resistance R2 do not change.And for Redundant Control loop, lower end fixed contact and lower end moving contact close, the magnitude of voltage that will be resistance R3 two ends that PEPS collects, relatively, the two is obviously different, now, the switching signal collected is sent to PDU by by CAN by PEPES, and PDU carries out electric source modes control according to normal power mode steering logic.
If the switching signal that PDU and PEPS collects is not identical, then illustrate that primary power control loop exists fault, adds up the number of stoppages, if this statistics exceedes setting value, then should report to the police.
If certain moment after detecting a failure, continuous several times detects that the switching signal that PDU and PEPS collects is identical again, then the number of stoppages should subtract 1.
In the present embodiment, be illustrated for automobile power source " shut " mode" OFF.The switching signal that the switching signal collected as PDU and PEPS detect is inconsistent, then illustrate that start button (the inner adhesion of start button, power on switch open circuit or open circuit) or the rigid line of connection start button go wrong, if when the aggregate-value monitoring number of times integrating counter DTC is more than or equal to " 50 ", now PDU will send prompt messages to PEPS and display C, and display C will point out user: " please continue to open car by start button 3S ".Now should advise that user keeps in repair the hardware circuitry of vehicle in time, to avoid danger.
If PDU does not detect the trigger pip from start button (double-pole single throw S1), and have received the button trigger pip that PEPS sends, then may be starting switch open fault or the rigid line fault connecting start button.Now, DTC is charged to by accumulative for the number of times of the PEPS signal received.The signal that PEPS sends often detected, counter DTC adds " 5 ", arrange count upper-limit for " 120 " secondary.If in a certain moment afterwards, PDU is the continuous triggered as normal signal monitored for 5 times from start button again, then should immediately DTC counter be subtracted " 1 ", do like this is because take into account the sporadic fault of automobile, namely think and only have the signal homogeneous phase that detects as the PDU signal to detect for continuous 5 times and PEPS simultaneously, just offset 1 failure count, ensure that the reliability of breakdown judge process.
If main power control loop fault detected, then PDU will receive the trigger pip of being sent by bus from PEPS, when PDU receives keystroke pattern confirmation signal for subsequent use from PEPS, PDU confirms that keystroke pattern for subsequent use works, and PDU will control the correct power initiation pattern of automobile starting.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
