Specific implementation mode
Further explanation is done to the present invention below in conjunction with the accompanying drawings.
As shown in Figs 1-4, a kind of vehicle prevents knock into the back early warning and avoiding system, feature from existing in case of the high-speed travel state In:Including signal acquisition module, control module and execution module, the signal acquisition module includes 1 He of laser range sensor Photoelectric sensor 2, the control module include signal processor 5 and comparison circuit 6, and the execution module includes display 3, bee Ring device 4 and auxiliary brake 7,
Wherein:The laser range sensor 1 and photoelectric sensor 2 are separately connected the input terminal of signal processor 5, signal The output end of processor 5 is separately connected 6 input terminal of comparison circuit and display, and the output end of the comparison circuit 6 is separately connected Buzzer 4 and auxiliary brake 7;The laser range sensor 1 and photoelectric sensor 2 are installed on own vehicle headstock, described aobvious Show that device 3 and buzzer 4 are installed on oneself car portion, display 3 is specifically installed on oneself interior windshield rear, is convenient for driver Observation, buzzer 4 are specifically mounted on own vehicle steering wheel, and the signal processor 5 is mounted on own vehicle steering wheel in the following, described For comparison circuit 6 in the bonnet of own vehicle after laser range sensor 1, the auxiliary brake 7 connects own vehicle braking Pedal, brake pedal are the brake pedal of own vehicle.
The laser range sensor 1, the distance signal for acquiring own vehicle and front vehicles.
The photoelectric sensor 2 is two, is respectively arranged in the both sides of own vehicle headstock, opposite with the tail-light of front vehicles It answers;The photoelectric sensor 2 is used to acquire the brake modulating signal of front vehicles.
The signal processor 5 is the microcontroller of model AT89S52.
The display 3 is installed on the hollow operations platform of oneself car, and display 3 is specifically installed on own car and keeps out the wind glass Glass rear is observed convenient for driver, and the display 3 is for the own vehicle of real-time display at a distance from front vehicles.
The buzzer 4 includes low frequency indicating alarm sound and high-frequency indicating alarm sound, wherein:Low frequency indicating alarm Sound is for prompting driver's front vehicles to have brake deceleration action;High-frequency indicating alarm sound is for prompting the own vehicle of driver It knocks into the back risk with front vehicles, if buzzer is after sending out high-frequency indicating alarm sound, driver does not take retarding braking Measure, the system just start auxiliary brake, increase the safe distance with front truck, automobile is avoided to send out in case of the high-speed travel state Raw rear-end collision.
The auxiliary brake 7 is pressure sensor, and the pressure sensor is stepped on by the own vehicle braking of solenoid valve control Plate, the brake pedal are brake pedal.
As shown in Fig. 2, the principle of the present invention is:Laser range sensor 1 acquires own vehicle and the distance signal of front vehicles, And transmit a signal to signal processor 5;Photoelectric sensor 2 acquires front vehicles brake modulating signal, and transmits a signal to letter Number processor 5;The signal transmission that signal processor 5 transmits the former is to comparison circuit 6 and display 3;Display 3 receives To signal processor 5 transmit range information can real-time display at a distance from front vehicles;Comparison circuit 6 receives signal processing The brake modulating signal and range information that device 5 transmits, comparison circuit information of adjusting the distance are compared, and comparison principle is as follows:
1) front brake lamp lights, but two vehicles distance is more than safe distance (D>S), comparison circuit 6 sends out buzzer 4 low The control signal of frequency alarm, buzzer 4 send out low frequency indicating alarm sound, and driver's front vehicles is reminded to have brake deceleration row For;
2) two vehicles distance is less than safe distance but is more than critical distance (DS<D<S), comparison circuit 6 sends out height to buzzer 4 The control signal of frequency alarm, buzzer 4 send out high-frequency indicating alarm sound, and the own vehicle of driver and front vehicles is reminded to knock into the back wind Danger;
3) two vehicles distance is less than critical distance (D<DS), comparison circuit 6 sends out self-stopping control to auxiliary brake 7 Signal processed, makes brake pedal execute brake function and reduces speed, to increase and leading vehicle distance, to prevent rear-end collision.
As shown in figure 3, buzzer is controlled through signal processor and comparison circuit, there are two types of different working conditions, i.e., high Frequency working condition and low frequency operation state:
Laser range sensor is collected distance signal and photoelectric sensor collected front truck brake modulating signal It is transferred to signal processor, comparison circuit is transferred to by signal processor, D is relatively determined by comparison circuit>S, it is more electric Road sends out buzzer the control signal of low frequency alarm, and buzzer is in low frequency operation state at this time, sends out the alarm song of low frequency, Driver's front vehicles are reminded to have brake deceleration behavior.If relatively determining D by smart circuitS<D<S, comparison circuit is to buzzing Device sends out the control signal of high frequency alarm, and buzzer is in high-frequency work state at this time, sends out the alarm song of high frequency, and warning drives Member between front truck at a distance from already less than safe distance, have the risk to knock into the back.
If as shown in figure 4, relatively determining D by comparison circuit<DS, built-in pressure of the comparison circuit to auxiliary brake Sensor sends out control signal, and brake is executed by solenoid valve to control brake pedal to control solenoid valve by pressure sensor Function, and then self-actuating brake reduces speed, increasing and leading vehicle distance, prevents rear-end collision.
The present invention can not only send out low-and high-frequency alarm and reminding driver note that can also react automatic not in time in driver Start auxiliary brake and carry out self-actuating brake, more safely and effectively prevents the generation of rear-end collision.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered It is considered as protection scope of the present invention.
