Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In order to realize the purpose of handoff-security electric motor vehicle gears, protection electric vehicle master controller and safe driving, the present invention
Embodiment provides a kind of electric motor vehicle gears control method, and details are as follows:
Fig. 1 shows the implementation process of electric motor vehicle gears control method provided in an embodiment of the present invention, wherein described electronic
Vehicle is provided with driving switch and motor, and motor drives the vehicle wheel rotation of electric vehicle.For ease of description, Fig. 1 is illustrated only and this
The relevant part of inventive embodiments, details are as follows:
In step s101, after electric vehicle powers on, judge whether the port level state of driving switch corresponds to neutral gear shelves
Position.
Wherein, the gear of electric vehicle there are forward gear and forward gear driving switch corresponding with forward gear, reverse drive gear and with
The corresponding reverse drive gear driving switch of reverse drive gear and neutral gear and neutral gear driving switch corresponding with neutral gear.Forward gear driving switch with
Reverse drive gear driving switch can export forward gear driving switch port level and reverse drive gear driving switch port level, neutral gear shelves respectively
Bit switch is exported without neutral gear driving switch port level.It is opened by acquisition forward gear driving switch port level, reverse drive gear gear
It closes port level and neutral gear driving switch port level may determine that whether the port level state of neutral gear driving switch corresponds to
Neutral gear gear.
Step S101 includes:
Judge whether port level state corresponding to the drive shift and reverse drive gear of driving switch is invalid state；
If so, determining that the port level state of driving switch corresponds to neutral gear gear；
If not, it is determined that the port level state of driving switch does not correspond to neutral gear gear.
Wherein, the port of forward gear driving switch not output level when, illustrate the port level shape of forward gear driving switch
State is invalid state.The port of reverse drive gear driving switch not output level when, illustrate the port level shape of reverse drive gear driving switch
State is invalid state.
In step s 102, if port level state does not correspond to neutral gear gear, motor stalling is controlled.
In step s 103, if port level state corresponds to neutral gear gear, the port electricity of real-time detection driving switch
Level state, and judge whether the port level state of driving switch is in multiple when the port level state of driving switch changes
Level while effective state.
Wherein, judge whether the port level state of driving switch is in multiple level while the purpose of effective state exists
In judging driving switch with the presence or absence of failure.The port level state of driving switch is in multiple level, and effective state is said simultaneously
There are failures for bright driving switch.Such as: in the trouble-free situation of driving switch, if driving switch is struck to forward gear,

Any reference value then illustrates to drive at this time in the hole.In practical applications, current of electric reference value, motor speed ginseng
20A, speed 200rmp and 1.5V can be respectively set to by examining value and throttle voltage reference value.
Specifically, step S106 includes:
The electric current of motor, revolving speed and throttle voltage are sampled to obtain the current sampling value of motor, revolving speed sampling value
And throttle voltage sampling value.
Judge whether current sampling value, revolving speed sampling value and throttle voltage sampling value are not more than current reference value respectively, turn
Fast reference value and throttle voltage reference value, if so, determining that the operating parameter of motor meets default safe operating conditions；If it is not,
Then determine that the operating parameter of motor does not meet default safe operating conditions.
In step s 107, if the operating parameter of motor does not meet default safe operating conditions, control motor according to
Operational taps before update are operated, or control motor stalling.
In step S108, if the operating parameter of motor meets default safe operating conditions, updated fortune is judged
Whether row gear is corresponding with the port level state of current gear switch.
Herein it should be noted that different operational taps correspond to the port level shape of different current gear switches
State, so after updating operational taps, therefore, to assure that the port level state phase that updated operational taps are switched with current gear
It is corresponding.
In step S109, if so, control motor is operated according to the operational taps of update.
In step s 110, if it is not, then controlling motor stalling.
Fig. 2 shows another implementation processes of electric motor vehicle gears control method provided in an embodiment of the present invention, in step
After S109, electric motor vehicle gears control method further include: step S111.
In step S111, judge electric vehicle with the presence or absence of operation troubles.
Wherein, electric vehicle there are operation troubles can be electric vehicle at runtime happen suddenly brake control or other may hinder
The failure for hindering electric vehicle to operate normally.
In step S112, if so, control electric vehicle is out of service.
In step S113, if it is not, then controlling the control behaviour of electric vehicle operation or the execution of control electric vehicle with driver
Make corresponding function.
