Equipment cost is saved.Specifically, before the step of judgement vehicle is lighted a fire, further includes:
Step S40 judges vibrating sensor when the current voltage value detected is greater than the preceding voltage value once detected
Whether vibration information is detected；
When vibrating sensor detects vibration information, the vehicle igniting is just determined.
Vibrating sensor is set on an engine in a vehicle, and the vibrating sensor is electrically connected with processor, the vibration
The vibration information sensed is sent to processor in real time or periodically by sensor.The current electricity detected is set in the present embodiment
When pressure value is greater than the preceding voltage value once detected, prejudge whether vibrating sensor detects vibration information, in the vibration
When dynamic sensor detects the vibration information, the vehicle igniting is just determined.
When due to engine ignition, engine can generate biggish vibration, therefore in order to ensure the accuracy of igniting judgement, knot
The detection of OBD interface voltage and Vehicular vibration detection are closed, when both meeting preset condition, then determines the vehicle igniting.
Further, before the step of judgement vehicle is lighted a fire, further includes:
Step S50 obtains vibration frequency, wherein the vibration information packet when vibrating sensor detects vibration information
Include vibration frequency；
Step S60, judges whether the vibration frequency reaches default vibration frequency；
When the vibration frequency reaches the default vibration frequency, the vehicle igniting is just determined.
Vibrating sensor determines Vehicular vibration according to vibration frequency during detecting vibration.Set the default of vehicle
Vibration frequency, the default vibration frequency are the vibration frequency in the case of vehicle retrofire, are reached in the vibration frequency got
When to the default vibration frequency, the vehicle igniting is just determined, to further increase the accuracy that vehicle igniting determines.
In other embodiments, the vibration information further includes vibration time etc., if vehicle is lighted a fire in unsuccessful situation,
Vibrating sensor can detecte Vehicular vibration, but vibrating is in a flash, if determining vehicle at this time, to occur determining fault
Situation.Therefore be arranged when vibrating sensor detects vibration information, obtain vibration time, wherein the vibration information includes vibration
Dynamic duration, judges whether vibration time reaches default time of vibration, when the vibration time reaches default vibration time, just sentences
The fixed vehicle igniting, further increases the judgment accuracy of vehicle igniting.
The present embodiment combines the voltage and Vehicular vibration information of detection OBD interface, changes and examines in OBD interface voltage
When having measured Vehicular vibration information, just determines vehicle igniting, can effectively prevent generation when other factors cause voltage change
Erroneous judgement situation occur, therefore the vehicle of the present embodiment igniting Detection accuracy it is higher.
Referring to Fig. 4, vehicle igniting detection method 3rd embodiment provided by the invention, the present embodiment is based on above-mentioned all realities
Example is applied, energy-efficient purpose is based on, after vehicle stall, OBD interface continues to the mobile unit power supply of vehicle in order to prevent, so that
