Description
Technical field
The present invention relates to new energy vehicle technical field, especially a kind of operating method of electric car reverse anti-collision system.
Background technology
With energy crisis and the pressure of environmental protection, new energy vehicle, especially electric automobile are increasingly by the joyous of people
Meet.Vehicle increases on road, and human pilot is needed to take the operation of each side into account comprehensively, and operation difficulty is increased, especially moved backward
When, due to human pilot limited view, it is impossible to timely find the barrier at rear, it is easy to crash.Especially pin
Consumer objects to electric automobile are mostly the elderly, and reversing safe distance is more difficult to control, or even will accelerate to work as by mistake to stop
Car, this is just easy to that contingency occurs.Once similar emergency occurs, existing electric automobile, which lacks corresponding meet an urgent need, arranges
Apply, accident can not avoid.In view of the shortcomings of the prior art, the present invention provides a kind of operation side of electric car reverse anti-collision system
Method.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of behaviour of electric car reverse anti-collision system
Make method, can effectively prevent reverse collision, realize automatic stopping, reversing can be automatically controlled by control system completely, be driven
Member only need to control direction, simple in construction, easily operated, facilitate human pilot to move backward, effectively avoid reverse collision
The generation of accident, the comfortableness and security of vehicle are improved, it is convenient to be provided for people's trip.
The present invention to achieve these goals, adopts the following technical scheme that：A kind of operation of electric car reverse anti-collision system
Method, the electric car reverse anti-collision system be by：Radar probe, processor, controller, motor, loudspeaker are formed；Motor and electricity
Differential mechanism in the middle part of motor-car back axle is correspondingly arranged, and being connected between motor and processor by wire sets controller, processor one
Side is connected by wire sets loudspeaker, at least three radar probes is uniformly distributed on the rear bumper of electric car, each radar is visited
Wire is set between head and processor；
The operating method is as follows：
The alarm distance A of longtime call of horn is first set on the controller, and setting can reverse motor moment, force electronic
Car stops the critical distance B of reversing；In reversing process, enabling signal is transferred to assembling through processor and existed driver by controller
Each radar probe on rear bumper, make radar probe launch ultrasonic wave, meet barrier after resilience reflex to radar probe, thunder
The ultrasonic wave reflected is received up to probe and passes to processor, and processor receives the ultrasonic analysis reflected and calculated
Actual range between the rear bumper and barrier of electric car, processor extremely control the actual range real-time delivery calculated
Device, controller compare actual range with alarm distance A, and when actual range is less than alarm distance A, controller is by alarm signal
Number being transferred to loudspeaker through processor makes longtime call of horn alarm, and when actual range reaches capacity distance B, controller is by stop sign
Motor is transferred to, reverses motor moment, forces electric car to stop reversing.
At least one especially Warning alarm distance is set on the controller between alarm distance A and critical distance B, it is special
When other Warning alarm distance be two or more, two neighboring especially Warning alarm apart from the distance between, or the limit away from
The sound that loudspeaker corresponding to the distance between with a distance from the special Warning alarm adjacent thereto from B are sent differs.
The beneficial effects of the invention are as follows：The present invention can effectively prevent reverse collision, realize automatic stopping.Reversing can be complete
Automatically controlled entirely by control system, driver need to only control direction, simple in construction, easily operated, facilitate human pilot
Reversing, effectively avoids the generation of reverse collision accident.The comfortableness and security of vehicle are improved, for people trip provider
Just.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is general assembly structural representation；
In Fig. 1：Radar probe 1, processor 2, controller 3, motor 4, loudspeaker 5.
Embodiment
The present invention is described in further detail with embodiment with reference to embodiment：
Embodiment 1
Motor 4 is correspondingly arranged with the differential mechanism in the middle part of motor rear axle, is connected between motor 4 and processor 2 by wire
Controller 3 is set, and the side of processor 2 is connected by wire sets loudspeaker 5, and at least three are uniformly distributed on the rear bumper of electric car
Individual radar probe 1, wire is set between each radar probe 1 and processor 2；
The operating method is as follows：
The alarm distance A of longtime call of horn is first set on controller 3, and setting can reverse the moment of motor 4, force electricity
Motor-car stops the critical distance B of reversing；For driver in reversing process, enabling signal is transferred to dress by controller 3 through processor 2
Fit over each radar probe 1 on rear bumper, make radar probe 1 launch ultrasonic wave, meet barrier after resilience reflex to radar
Probe 1, radar probe 1 receive the ultrasonic wave reflected and pass to processor 2, and processor 2 receives the ultrasound reflected
Wave analysis calculates the actual range between the rear bumper of electric car and barrier, the actual range that processor 2 will calculate
Real-time delivery to controller 3, controller 3 compares actual range with alarm distance A, when actual range is less than alarm distance A
When, alarm signal is transferred to loudspeaker 5 by controller 3 through processor 2 makes longtime call of horn alarm, when actual range reaches capacity distance
During B, stop sign is transferred to motor 4 by controller 3, reverses the moment of motor 4, forces electric car to stop reversing.
Embodiment 2
At least one especially Warning alarm distance is set on the controller 3 between alarm distance A and critical distance B,
When special Warning alarm distance is two or more, the distance between two neighboring especially Warning alarm distance, or the limit
The sound that loudspeaker 5 corresponding to the distance between special Warning alarm distance adjacent thereto distance B are sent differs.
