An advantage of the present invention is, suppresses when flame-out when manual gear vehicle, can restart convenient and safely driving engine.
Accompanying drawing explanation
After having read the specific embodiment of the present invention with reference to accompanying drawing, those skilled in the art will become apparent various aspects of the present invention.One skilled in the art will appreciate that these accompanying drawings are only for coordinating the specific embodiment that technical scheme of the present invention is described, and be not intended to protection scope of the present invention to be construed as limiting.Wherein,
Fig. 1 is according to the structural representation of the engine restarting control system for manual gear vehicle of the embodiment of the present invention.
The specific embodiment
With reference to the accompanying drawings, the specific embodiment of the present invention is described in further detail.
Fig. 1 is according to the structural representation of the engine restarting control system for manual gear vehicle of the embodiment of the present invention.As shown in Figure 1, engine restarting control system comprises information acquisition subsystem, starter controller and starter.Information acquisition subsystem comprises bit switch at the bottom of key position switch, neutral position switch, clutch pedal, engine speed sensor and car load network.Starter controller can receive key position signal from key position switch, receive engine rotational speed signal from engine speed sensor, receive shift signal from neutral position switch, receive clutch pedal position signal from bit switch at the bottom of clutch pedal, and receive vehicle speed signal from car load network.Key position signal can comprise OFF(off position), ON(open position), START(enable position).Whether shift signal indication gear is for neutral position state.Whether clutch pedal position signal indication clutch pedal position is for position, the end, and whether clutch pedal is floored.
According to the embodiment of the present invention, starter controller is judging that driving engine suppresses when flame-out, can be floored or gear is suspended to the signal that neutral sends and restarts driving engine by pedal of clutch, and do not carried out start the engine by the position that key is screwed to START.Further, before restarting driving engine, at the bottom of starter controller also will judge neutral position switch and clutch pedal, whether bit switch once there is fault, because occurred at the bottom of the neutral position switch of fault and clutch pedal that bit switch will make to restart dangerous, caused starter misoperation.
In one embodiment, starter controller is configured to:
Suppress flame-out when judging driving engine, and when at the bottom of judgement neutral position switch and clutch pedal there is not fault in bit switch, indicate clutch pedal position in position, the end in response to shift signal indication gear in neutral or in response to clutch pedal position signal, and control starter, driving engine is activated, wherein
When key position signal be ON, shift signal indication gear in non-neutral and clutch pedal position signal indication clutch pedal position not in position, the end and engine rotational speed signal indication engine speed to fall be 0, starter controller judgement driving engine is suppressed flame-out
When vehicle speed signal indication vehicle accelerates under throttle effect, and shift signal indicates gear in the time of neutral, and starter controller judges that neutral position switch breaks down,
When vehicle speed signal indication vehicle accelerates under throttle effect, and clutch pedal position signal indicates clutch pedal position in the time of position, the end, and at the bottom of starter controller is judged clutch pedal, bit switch breaks down.
In another embodiment, a kind of engine restarting control method for manual gear vehicle is disclosed, the method comprises the following steps: judge driving engine when starter controller and suppress flame-out, and when at the bottom of judgement neutral position switch and clutch pedal there is not fault in bit switch, starter controller indicates clutch pedal position in position, the end in response to shift signal indication gear in neutral or in response to clutch pedal position signal, and control starter, driving engine is activated.
