Specific embodiment
Embodiments of the invention are described below in detail, the example of described embodiment is shown in the drawings, wherein from start to finish
The module that same or similar label represents same or similar module or has same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.On the contrary, originally
Inventive embodiment includes falling into all changes in the range of the spirit of attached claims and intension, modification and equivalent
Thing.
Fig. 1 is the schematic flow sheet of the control method of electro-motive vehicle that one embodiment of the invention proposes, and the method includes：
S11：Judge whether electro-motive vehicle is in on-position.
Wherein, it is provided with brake pedal in electro-motive vehicle, brake pedal can produce brake signal (brake), according to
Driver's whether brake pedal, the specifically different value of brake signal, whether vehicle be can determine according to the value of brake signal
It is in on-position.
For example, during driver's brake pedal, brake=1, show that vehicle is in on-position, otherwise, driver does not have
When having brake pedal, brake=0, show that vehicle is not on on-position.
S12：If not in on-position, using full throttle priority acccess control strategy, described electro-motive vehicle is carried out
Control.
Under non-brake state, wagon control adopts full throttle priority acccess control strategy, for example, does not input in brake pedal
In the state of, as long as kick-down switch in accelerator pedal end is triggered, (for not having, can using of kick-down switch is complete
Throttle is substituting), no matter now which kind of fault vehicle has, the accelerator pedal that vehicle control unit controls vehicle responds driver is defeated
Enter.
The present embodiment passes through in non-brake state, using full throttle priority acccess control strategy, the event such as battery can
During barrier, ignore these faults and the still input according to driver controls vehicle, thus above-mentioned height in electro-motive vehicle
During grade fault, still can be advanced according to the input of driver or retreat it is ensured that personal safety.
Fig. 2 is the schematic flow sheet of the control method of electro-motive vehicle that another embodiment of the present invention proposes, the method bag
Include：
S201：Judge whether electro-motive vehicle is in on-position, if so, execute S205, otherwise execute S202.
For example, as brake=1, determine that vehicle is in on-position, otherwise, as brake=0, show that vehicle does not have
It is in on-position.
S202：Judge whether described electro-motive vehicle is in full throttle instruction state, if so, execute S203, otherwise, execution
S206.
Optionally, described judge whether described electro-motive vehicle is in full throttle instruction state, including：
When described electro-motive vehicle has and steps on switch completely, step on, according to described, the signal judgement that switch produces completely
Whether described electro-motive vehicle is in full throttle instruction state；Or,
When described electro-motive vehicle does not have and steps on switch completely, described electric drive car is judged according to throttle wide signal
Whether it is in full throttle instruction state.
Wherein, step on switch completely and can represent, throttle wide signal can use (WOT, Wide with kick-down switch
OpenThrottle) signal represents.
Kick-down switch is arranged on the end of accelerator pedal, when the complete bend the throttle of driver, kick-
Down switch is in triggering state, and now the value of kick-down switch is kick-down=1, therefore, works as kick-down=1
When, determine that vehicle is in full throttle instruction state.Or,
When vehicle does not have kick-down switch, vehicle would generally produce WOT signal, when driver adopts full throttle
When, WOT=110%, therefore, as WOT=110%, determine that vehicle is in full throttle instruction state.
It is, of course, understood that above-mentioned each concrete numerical value is a kind of example however it is not limited to above-mentioned numerical value, different factories
The corresponding full throttle instruction of the vehicle of business can arrange different numerical value.
S203：Judge whether described electro-motive vehicle is in charged state, if so, execute S207, otherwise, execute S204.
Wherein it is possible to judge whether to be in charged state according to charging indication signal.
S204：Input driving moment according to driver.
For example, under non-brake state, when driver completes bend the throttle, if not in charged state, then
No matter any fault, all the full throttle instruction of response driver in vehicle, drives vehicle to advance or retreats etc..
S205：Car load is in on-position.
The present embodiment is preferential using braking, for example, during driver's brake pedal, vehicle is braked with control, no
Input to again any throttle of engine, keep vehicle to stop moving.
S206：Car load is in normal control state.
For example, when driver increases throttle input, carry out vehicle acceleration etc..
S207：No starting, continues to charge.
When vehicle is in charged state, ignore the input of driver, keep charged state.
Current electro-motive vehicle, when high-grade fault in the critical system such as battery or motor, may adopt
Force electrically operated under high pressure, lead to vehicle can not drive.But, when vehicle is in the crisis shape such as level crossing and tsunami attack
During state, now driver needs to drive escape, rather than protection vehicle.In the present embodiment, by full-vehicle control plan
One highest priority service of setting, when driver explicitly indicates that and needs to drive vehicle, no matter vehicle-state how, and vehicle is equal
Obey the input of driver and drive advance or retreat, thus vehicle can also be according to driving in faults such as batteries in times of crisis
The input of the person of sailing and drive it is ensured that personal safety.
Fig. 3 is the structural representation of the control device of electro-motive vehicle that another embodiment of the present invention proposes, this device 30
Including the first judge module 31 and strategic control module 32.

Whether it is in full throttle instruction state.
Wherein, step on switch completely and can represent, throttle wide signal can use (WOT, Wide with kick-down switch
Open Throttle) signal represents.
Kick-down switch is arranged on the end of accelerator pedal, when the complete bend the throttle of driver, kick-
Down switch is in triggering state, and now the value of kick-down switch is kick-down=1, therefore, works as kick-down=1
When, determine that vehicle is in full throttle instruction state.Or,
When vehicle does not have kick-down switch, vehicle would generally produce WOT signal, when driver adopts full throttle
When, WOT=110%, therefore, as WOT=110%, determine that vehicle is in full throttle instruction state.
It is, of course, understood that above-mentioned each concrete numerical value is a kind of example however it is not limited to above-mentioned numerical value, different factories
The corresponding full throttle instruction of the vehicle of business can arrange different numerical value.
