Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar module or has module that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.On the contrary, embodiments of the invention comprise fall into attached claims spirit and intension within the scope of all changes, amendment and equivalent.
Fig. 1 is the schematic flow sheet of the control method of the electro-motive vehicle that one embodiment of the invention proposes, and the method comprises:
S11: judge whether electro-motive vehicle is in braking mode.
Wherein, be provided with brake pedal in electro-motive vehicle, brake pedal can produce speed-slackening signal (brake), whether steps on brake pedal according to chaufeur, according to the value of speed-slackening signal, the value that speed-slackening signal is specifically different, can determine whether vehicle is in braking mode.
Such as, when chaufeur steps on brake pedal, brake=1, shows that vehicle is in braking mode, otherwise when chaufeur does not step on brake pedal, brake=0, shows that vehicle is not in braking mode.
S12: if be not in braking mode, adopts full throttle priority acccess control strategy, controls described electro-motive vehicle.
Under non-brake state, wagon control adopts full throttle priority acccess control strategy, such as, under the state that brake pedal does not input, as long as acceleration pedal end kick-down switch is triggered (for not having can substituting with full throttle of kick-down switch), no matter which kind of fault now there is in vehicle, the acceleration pedal input of vehicle control unit controls vehicle response chaufeur.
The present embodiment is by when non-brake state, adopt full throttle priority acccess control strategy, can when there is the faults such as battery, ignore these faults and still according to the input control vehicle of chaufeur, thus when above-mentioned high-grade fault appears in electro-motive vehicle, still can advance according to the input of chaufeur or retreat, ensure personal safety.
Fig. 2 is the schematic flow sheet of the control method of the electro-motive vehicle that another embodiment of the present invention proposes, and the method comprises:
S201: judge whether electro-motive vehicle is in braking mode, if so, performs S205, otherwise perform S202.
Such as, as brake=1, determine that vehicle is in braking mode, otherwise, as brake=0, show that vehicle is not in braking mode.
S202: judge whether described electro-motive vehicle is in full throttle indicating status, if so, performs S203, otherwise, perform S206.
Optionally, describedly judge whether described electro-motive vehicle is in full throttle indicating status, comprising:
When described electro-motive vehicle have step on switch completely time, according to described step on completely switch produce signal judge whether described electro-motive vehicle is in full throttle indicating status; Or,

Wherein, stepping on switch completely can represent with kick-down switch, and throttle wide signal can use (WOT, Wide OpenThrottle) signal indication.
Kick-down switch-linear hybrid is at the end of acceleration pedal, and when the complete bend the throttle of chaufeur, kick-down switch is in trigger state, now the value of kick-down switch is kick-down=1, therefore, as kick-down=1, determine that vehicle is in full throttle indicating status.Or,
When vehicle does not have kick-down switch, vehicle can produce WOT signal usually, and when chaufeur adopts full throttle, WOT=110%, therefore, as WOT=110%, determines that vehicle is in full throttle indicating status.
Certainly, be understandable that, above-mentioned each concrete numerical value is a kind of example, is not limited to above-mentioned numerical value, and the corresponding full throttle instruction of vehicle of different vendor can arrange different numerical value.
S203: judge whether described electro-motive vehicle is in charge condition, if so, performs S207, otherwise, perform S204.
Wherein, can judge whether to be in charge condition according to charging indicator signal.
S204: according to the input queued switches wheel of chaufeur.
Such as, under non-brake state, when chaufeur completes bend the throttle, if be not in charge condition, then no matter if there is any fault in vehicle, all responds the full throttle instruction of chaufeur, drive vehicle advance or retrogressing etc.
S205: car load is in braking mode.
The present embodiment adopts braking preferential, such as, when chaufeur steps on brake pedal, carries out control for brake to vehicle, no longer gives driving engine any throttle input, keeps vehicle to stop mobile.
S206: car load is in normal control state.
Such as, when chaufeur increases throttle input, vehicle acceleration etc. is carried out.
S207: No starting, continues charging.
When vehicle is in charge condition, ignore the input of chaufeur, keep charge condition.
Current electro-motive vehicle, when high-grade fault appears in the critical system such as battery or motor, may adopt electricity under forcing high pressure to operate, cause vehicle not drive.But when vehicle is in the crisis state such as level crossing and tsunami attack, now chaufeur needs to drive escape, instead of protection vehicle.In the present embodiment; by arranging an operational priority the highest in full-vehicle control plan; when chaufeur clearly represent need drive vehicle time; no matter vehicle-state how; vehicle is all obeyed the input of chaufeur and drives advance or retreat; thus vehicle also can drive according to the input of chaufeur when faults such as batteries in times of crisis, ensures personal safety.
