Parking system provided by the present invention and method of parking, in reversing process, when the electric automobile and the barrier
When hindering the area to reach risk distance, the power of the driving force of the motor output is less than preset value, and then causes even in
Bend the throttle during car, the electric automobile also will not directly accelerate, but slow reversing, moved backward so as to reduce
During caused by the maloperation to accelerator pedal security incident, ensured safety of person vehicle.
【Brief description of the drawings】
Fig. 1 is the illustrative view of functional configuration of the electric automobile provided in the embodiment of the present invention.
Fig. 2 is the flow chart of the method for parking provided in the embodiment of the present invention.
【Embodiment】
In order that the purpose of the present invention, technical scheme and advantageous effects become apparent from understanding, below in conjunction with accompanying drawing and
Embodiment, the present invention will be described in further detail.It should be appreciated that the specific implementation described in this specification
Mode is not intended to limit the present invention just for the sake of explaining the present invention.
Referring to Fig. 1, it is the illustrative view of functional configuration of the electric automobile 100 provided in the embodiment of the present invention.The electricity
Electrical automobile 100 includes motor 10, electric machine controller 20 and parking system 30.Wherein, the motor 10 is used to carry
For driving force.The electric machine controller 20 is used for the driving force for controlling the motor 10 to export different capacity.It is described to park
System 30 is parked for auxiliary, and it includes detecting module 31, judge module 32 and radar for backing car 33.It is it is to be appreciated that above-mentioned
Each functional module can be stored in memory in form of software programs, and by computing device.Or there is specific function
Hardware, for example, burning have particular software application chip or with specific function device.
Above-mentioned each functional structure module is described in detail with reference to Fig. 2.
As shown in Fig. 2 its flow chart for method of being parked in the embodiment of the present invention.It should be noted that side of the invention
Method is not limited to the order of following step, and in other embodiment, method of the invention can only include step as described below
A portion, or part steps therein can be deleted.
Step S01, the detecting module 31 are used for the gear information for detecting the electric automobile 100, and will be described electronic
The current shift of automobile 100 is sent to the judge module 32.
The gear information of the electric automobile 99 includes：Parking shift (P), reverse gear shift R), neutral (N) and other gears,
For example, forward gear (D).It is appreciated that different according to the type of the electric automobile 100, the gear information is also different, at present
Electric automobile 100 mainly include manual gear and automatic catch.
Step S02, the judge module 32 are used to judge whether the current shift of the electric automobile 100 to be reverse gear shift,
If the current gear is reverse gear shift, detection instruction is sent to the radar for backing car 33.
Step S03, the radar for backing car 33 be used for according to it is described detection command detection described in electric automobile 100 safety away from
Whether there is barrier from the range of, if barrier be present in the range of the safe distance of the electric automobile 100, send control and refer to
Order, and enter step S04；If barrier is not present in the range of the safe distance of the electric automobile 100, continue to detect.Can
To understand, if barrier in the range of the safe distance of the electric automobile 100 be present, the radar for backing car 33 refers to sending control
It can also be alarmed while order to prompt driver's careful driving.
Step S04, the electric machine controller 20 is used to receive the control instruction, and controls institute according to the control instruction
State the driving force that the power output of motor 10 is less than predetermined value.
It is appreciated that the safe distance is integrates the limit drawn according to the indices of the electric automobile 100
Value.When the electric machine controller 20 receives the control instruction, that is, when barrier and the electric automobile 100 reach
During risk distance, even if bend the throttle, the electric automobile 100 also will not directly accelerate, but slow reversing, so as to subtract
Lack in reversing process the security incident caused by the maloperation to accelerator pedal, ensure safety of person vehicle.
Parking system 30 provided by the present invention and method of parking, in reversing process, when the electric automobile 100 and institute
When stating barrier and reaching risk distance, the power of the driving force of the motor output is less than preset value, even and if then so that
The bend the throttle in reversing process, the electric automobile 100 also will not directly accelerate, but slow reversing, so as to reduce
In reversing process caused by the maloperation to accelerator pedal security incident, ensured safety of person vehicle.
The present invention is not restricted to described in specification and embodiment, therefore for the personnel of familiar field
Additional advantage and modification is easily achieved, therefore in the essence of the universal limited without departing substantially from claim and equivalency range
