Stream, needed for foot short circuit judgement to be collected during number, all operating currents collected, which add up, to be averaged to obtain
Short-circuit average value if short-circuit average value is more than short-circuit calibration value, judges that short trouble occurs for Brake lamp, if short circuit is average
Value is less than or equal to short circuit calibration value, then the acquisition of operating current continues, until number needed for acquisition foot open circuit judgement, this
When, all operating currents collected, which add up, to be averaged to obtain open circuit average value, if open circuit average value is small
In open circuit calibration value, then judge that open fault occurs for Brake lamp, if open circuit average value is more than or equal to open circuit calibration value, brake
Lamp is without faulty.
7. a kind of Rear Fog Lamp according to claim 6 substitutes the application method of braking lamp control system, it is characterised in that:Institute
State short circuit judge needed for number as 8-50 times, it is described open a way judge needed for number as 100-300 times.
8. a kind of Rear Fog Lamp according to claim 7 substitutes the application method of braking lamp control system, it is characterised in that:Institute
State short circuit judge needed for number as 40 times, it is described open a way judge needed for number as 280 times.
9. a kind of Rear Fog Lamp according to claim 6 substitutes the application method of braking lamp control system, it is characterised in that institute
It states application method and further includes replacement and prompting technique after braking lamp failure, the replacement after the braking lamp failure is with prompting technique bag
Include following steps:
When microprocessor chip (61) detects that short circuit or open fault occur for Brake lamp, microprocessor chip (61) passes through successively
Rear Fog Lamp signal harness (81), automobile-used Rear Fog Lamp driving chip (63) automobile-used Rear Fog Lamp (8) to be driven to light to substitute Brake lamp,
Meanwhile fault message is sent to instrument board (9) by microprocessor chip (61), to light malfunction indicator lamp (93), and in failure
Correspondence shows Chinese failure-description, failure code on literary description portion (921), failure code display unit (922).
10. a kind of Rear Fog Lamp according to claim 6 substitutes the application method of braking lamp control system, it is characterised in that institute
It states application method and further includes the automatic recovery technique after Brake lamp trouble shooting, the automatic recovery work after the Brake lamp trouble shooting
Skill comprises the following steps:
After short circuit or open fault occur for automobile-used Brake lamp (7), when microprocessor chip (61) receives brake switch (5)
When being closed the brake signal for transferring and, microprocessor chip (61) still attempts to export high level drive signal to automobile-used braking
Lamp driving chip (62), and the operating current that Brake lamp current feedback harness (72) is fed back is gathered, if work electricity can be collected
It flows, and the short-circuit average value for calculating gained is less than short-circuit calibration value or the open circuit average value of calculating gained is more than open circuit calibration value,
Then judge that automobile-used Brake lamp (7) has recovered, then close Rear Fog Lamp signal harness (81) immediately, give back the control of automobile-used Rear Fog Lamp (8)
System power.
