Member does not take brake measure in time, and one's own side driver does not also take acceleration scheme, then Acceleration of starting actuator comes into operation, and drives
Accelerator device works, until one's own side's vehicle decommissions after reaching safe distance with front vehicle, if in accelerator with before
The distance of square vehicle be less than safe distance after, then when front vehicles do not turn to, start turn to actuator, make car body turn to around
Front truck is crossed, effectively avoids being occurred by rear-end collision.
Further, described self-test unit is used to carry out self-test to vehicle in vehicle launch, whether judges the vehicle
Normally；Described outdoor visibility judging unit limits F-Zero according to the visibility degree for judging outdoor weather；Described
Spacing speed information conformity calculation unit distance measuring sensor, tachogenerator and car itself velocity sensor is surveyed the spacing that comes and
Speed is integrated, and described Calculation of Safety Distance unit calculates what should currently be kept according to itself speed and relative velocity
Safe distance.
Further, described distance measuring sensor is to be passed installed in headstock and the ultrasonic sensor of the tailstock or laser ranging
Sensor, described tachogenerator are the laser velocimeter sensor installed in headstock and the tailstock.
Further, described information processing system is connected with navigation app.
It is compared with prior art the advantages of the utility model with beneficial effect：Pass through configuration information acquisition system, letter
Processing system, warning system and executing agency are ceased, voice reporting is carried out when being less than safe distance with front vehicles or front vehicle
It is alert, in the case of less than safe distance minimum value driver still without emergency reaction, start brake or accelerate actuator to make car body
Acceleration or deceleration, it is necessary to when can also simultaneously start and turn to actuator and turn to car body, until detachment alarm, effectively avoid knocking into the back
With the danger knocked into the back.
