Concrete meaning in the present invention.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As illustrated in fig. 1 and 2, the present invention includes storage battery 1, controller 2, the following distance detector 3 for being fixed on front of the car, consolidates
The alarm device 4 being scheduled in vehicle drive room, the exhaust solenoid valve 5 on cylinder exhaust outlet, mounted on starting
On machine cylinder oil inlet into solenoid 6, mounted on driving indoor brake pedal, be fixed below brake pedal and incude
The brake pressure sensor 7 of the brake pedal depression degree is driven installation with brake pedal and the cooperation of engine crankshaft 10
Braking mechanism 8 pushes journey mounted on driving indoor gas pedal and be fixed below gas pedal and incude the gas pedal
The throttle pressure sensor 9 of degree;
Storage battery 1 and controller 2, alarm device 4, exhaust solenoid valve 5, are pressed into solenoid 6, brake at following distance detector 3
Force snesor 7, braking mechanism 8 and throttle pressure sensor 9 are electrically connected;
Following distance detector 3, brake pressure sensor 7 and throttle pressure sensor 9 are connect with 2 signal of controller, and to
2 input measurement signal of controller;
Controller 2 analyzes the relative velocity of vehicle headway and Adjacent vehicles according to measuring signal, and to alarm device 5, row
Pneumoelectric magnet valve 6 inputs corresponding control signal into the brake control terminal of solenoid 7 and braking mechanism 8.
Following distance detector 3 is laser sensor.
Alarm device 4 is voice siren device.
Braking mechanism 8 includes being relatively fixed on stand and positioned at a pair of electronic of 10 both sides of engine crankshaft
Push rod 81 and cushion 82, electric pushrod 81 include push rod control terminal 811 and the telescopic rod being electrically connected with push rod control terminal 811
812, push rod control terminal 811 is control terminal of braking, and cushion 82 is fixed on the top of telescopic rod 812.
The one side being in contact with engine crankshaft 10 on cushion 82 is to justify side with the engine crankshaft 10 to match
The arc-shaped curved surface of conjunction.
The both sides of engine crankshaft 10 are respectively with respect to the fixing axle 9 being fixed on equipped with one on stand, braking machine
Structure 8 is fixed in fixing axle 11.
The present invention the course of work be:Following distance detector 3 be laser sensor, laser sensor measure vehicle with
The distance between front Adjacent vehicles and relative velocity between the two, and by measuring signal input controller 2, controller 2
Calculate the safe stopping distance of vehicle according to vehicle travel speed, and according to safe stopping distance and vehicle with
The distance between front Adjacent vehicles and relative velocity between the two, judge the transport condition of vehicle;
When the distance between vehicle and front Adjacent vehicles and safe stopping distance are there are when larger gap, itself vehicle
It freely travels;
When the distance between vehicle and front Adjacent vehicles are close to safe stopping distance, and vehicle travel speed
When no more than front Adjacent vehicles travel speed, vehicle is still travelled according to raw velocity;
When the distance between vehicle and front Adjacent vehicles are close to safe stopping distance, and vehicle travel speed
When more than front Adjacent vehicles travel speed, for controller 2 to 4 input control signal of alarm device, alarm device 4 sends out voice police
Report, while feedback signal is conveyed to controller 2, vehicle driver mitigates Compressive Strength under gas pedal according to voice alarm,
Throttle pressure sensor 9 measures Compressive Strength under obtained gas pedal and reduces, which sends measuring signal
Controller 2, controller 2 convey control signal into solenoid 6, control the opening degree reduction into solenoid 6, reduce combustion
Fuel oil speed from oil burner nozzle to in-cylinder injection, and then reduce vehicle driving dynamics, reduce Vehicle Speed, if driver thinks
Travel speed is largely reduced, brake pedal can also be pushed, brake pressure sensor 7 measures the obtained intensity of pressure and increases
Greatly, measuring signal is sent to controller 1 by brake pressure sensor 7, and controller 1 sends control signal, push rod to braking mechanism 8
Control terminal 811 controls telescopic rod 812 and stretches out certain length, and cushion 82 generates certain extruding to engine crankshaft 10 and brakes
Power, vehicle gradually slow down;
When the distance between vehicle and front Adjacent vehicles are less than safe stopping distance, and the traveling speed of vehicle
When degree is far longer than front Adjacent vehicles travel speed, controller 2 is sent out to 4 input control signal of alarm device, alarm device 4
Voice alarm, while controller 2 sends closing control signal into solenoid 6, controls and is closed into solenoid 6, to exhaust
Solenoid valve 5 starts opening control signal, control exhaust solenoid valve 5 to open, and brake control signal, control are sent to braking mechanism 8
Braking mechanism 8 brake so that engine stop work while emergency braking, in order to vehicle quick deceleration, avoid with
Front Adjacent vehicles bump against;
The distance between Adjacent vehicles and opposite travel speed are measured using following distance detector 3, controller 1 is according to vehicle
Itself travel speed calculates the safe stopping distance of vehicle, in conjunction with the distance between Adjacent vehicles and opposite travel speed
Comprehensive analysis safe driving scheme, realizes and is automatically reminded to vehicular gap, and automatically controlled to emergency braking, for row
Vehicle provides a convenient safely.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
