Description
Technical field
The invention belongs to electric automobiles, more particularly to a kind of bumper car system of electric car.
Background technology
Electric car, i.e. electric drive vehicle, also known as electricity are driven.Electric car is divided into alternating current electric vehicle and DC electric car.Generally
The electric car said is using battery as energy source, by parts such as controller, motors, converts electrical energy into mechanical energy motion,
Change the vehicle of speed with control electric current size.Electric car provides great convenience for the trip of people.At the same time, it is electronic
Car easily occurs traffic accident, causes huge property loss because handling is poor, speed is fast, or even causes many
Casualties.Therefore a kind of system that electric car can be avoided to collide is needed badly.
The content of the invention
It is an object of the invention to provide a kind of bumper car system of electric car, and the bumper car system design is reasonable, can
Effectively solve the problems, such as the collision of electric car, improve riding safety, there is high use value.
The object of the present invention is achieved like this：A kind of bumper car system of electric car, including radar meter, distance pass
Sensor, speed control, microprocessor, alarm, described radar meter and range sensor are mounted on electric car
The signal output part of body structure, described radar meter and range sensor is connected to the signal input of microprocessor
End, the signal output part difference connection speed controller and alarm of described microprocessor, the connection of described speed control
Motor.
Described alarm is audible-visual annunciator.
Described microprocessor includes AD conversion unit, signal processing unit, mnemon, D/A conversion unit.
Described AD conversion unit connection microprocessor signals input, described signal processing unit connection modulus turn
Unit, described D/A conversion unit connection signal processing unit are changed, described microprocessor signals output end connection digital-to-analogue turns
Unit is changed, mnemon is also associated with described signal processing unit.
The beneficial effect comprise that：Electric vehicle anti-collision car system proposed by the present invention, passes through range sensor pair
The ranging of front vehicles or barrier, and itself electric car for measuring of radar meter and front electric car are relatively fast
Degree, is analyzed by the processing unit of microprocessor, and combines the information of itself electric car mnemon storage, judges this car
Whether in the range of the accident of barrier, speed is then automatically adjusted by speed control, and alarmed to human pilot, is avoided
This car bumps against with preceding vehicle either barrier.
Brief description of the drawings
Fig. 1 is flow circuit theory schematic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawings to embodiments of the invention further instruction.
Embodiment 1
As shown in Figure 1, the bumper car system of a kind of electric car, including radar meter, range sensor, speed control,
Microprocessor, alarm, described radar meter and range sensor are mounted on the body structure of electric car, described thunder
Signal output part up to tachymeter and range sensor is connected to the signal input part of microprocessor, described microprocessor
Signal output part difference connection speed controller and alarm, described speed control connection motor.
Described alarm is audible-visual annunciator.
Described microprocessor includes AD conversion unit, signal processing unit, mnemon, D/A conversion unit.
Described AD conversion unit connection microprocessor signals input, described signal processing unit connection modulus turn
Unit, described D/A conversion unit connection signal processing unit are changed, described microprocessor signals output end connection digital-to-analogue turns
Unit is changed, mnemon is also associated with described signal processing unit.
The present invention is when in use：Electric car in the process of moving, is installed on the range sensor of the body structure of electric car
With radar meter can to the ranging of car body front end vehicle or barrier, and measured by radar meter itself is electronic
The relative velocity of car and front electric car, these data are transferred to the AD conversion unit of microprocessor, AD conversion unit
Analog signal is converted into digital data transmission to signal processing unit, signal processing unit, which passes through, carries out processing point to data
Compared with analysis and the information with being stored in mnemon, judge this car whether in the range of the accident of barrier.If in accident
Scope, reduction of speed instruction is sent to speed control, speed control control motor turns down electronic vehicle speed, at the same time passes through report
Alert device is alarmed to cyclist.
Generally, the present invention has the advantages of collision problem that can effectively solve the problem that electric car, raising riding safety.
