The vehicle-mounted pedestrian protection system comprises vehicle speed sensors, an ultrasonic radar, speed sensors, a micro-control unit, a voice prompt system and an ABS. The vehicle speed sensors are arranged on wheels of the vehicle, the ultrasonic radar and the speed sensors are arranged on a front bumper, a front left fender and a front right fender respectively, and the ultrasonic radar, the speed sensors, the voice prompt system and the ABS are electrically connected with the micro-control unit. The vehicle-mounted pedestrian protection system detects the relative position and the relative speed of pedestrians and vehicles, and reminds the driver to brake and avoid the pedestrians in time; after reminding is carried out twice, braking can be carried out automatically to prevent accidents; low beam and high beam can be changed automatically to remind the pedestrians to avoid the vehicle.
Description
Technical field
The present invention relates to a kind of vehicle-mounted fender guard, particularly relate to a kind of vehicle-mounted pedestrian protection system.
Background technology
At present, traffic safety problem is subject to the extensive concern of society.Only have minority automobile that pedestrian protection has been installed in existing automobile, and great majority protect pedestrian by being provided with safety air bag in the bar of automobile front protecting danger.This technical scheme can cushion the impact to pedestrian really to a certain extent, thus reduce clash into injury, but occur after the car hit backward people that the reasons such as driver's operation error can not be avoided to cause roll accident.
Chinese patent Authorization Notice No.: CN101607545, the patent of invention in authorized announcement date on December 23rd, 2009 discloses a kind of method for protecting pedestrian for automotive front.Its object is to for the defect existing for prior art, provide that a kind of structure is simple, cost is low, the method for protecting pedestrian for automotive front of easy enforcement.Described method installs shock absorber at the inwall of front cover for vehicle; The position of described shock absorber is corresponding with the position of hard components below.When automobile and pedestrian collision, the upper body of pedestrian falls on the protecgulum of car front portion, protecgulum is pressed to hard object below as engine case etc.These hard components can cause the grievous injury of pedestrian under normal conditions; But now because shock absorber below absorbs the impact energy of pedestrian, cushion the shock strength of hard components to pedestrian, thus reach the effect of protection pedestrian.The weak point of this technical scheme be can only buffering automobile to the shock strength of pedestrian, but occur after the car hit backward people that the reasons such as driver's operation error can not be avoided to cause roll accident.
Summary of the invention
The present invention is to overcome pedestrian fender guard of the prior art; can only buffering collision of closed strength; the deficiency of the accident that rolls occurred after the car hit backward people that the reasons such as driver's operation error can not be avoided to cause; providing one can by detecting pedestrian and automobile relative position and relative velocity; and make reply reaction in advance; chaufeur is reminded to brake in advance or automatically brake, with a kind of vehicle-mounted pedestrian protection system avoiding automobile impacting pedestrian to cause traffic accident.
For achieving the above object, the present invention is by the following technical solutions:
A kind of vehicle-mounted pedestrian protection system of the present invention; comprise car speed sensor, ultrasonic radar, speed sensor, micro-control unit, speech prompting system and abs braking system; car speed sensor step is placed on automotive wheel; on the front bumper that ultrasonic radar and speed sensor are arranged in automobile and front left and right fender guard, ultrasonic radar, speed sensor, speech prompting system and abs braking system are electrically connected with micro-control unit respectively.
The present invention detects the distance of automobile and vehicle front pedestrian in real time by ultrasonic radar, speed sensor detects the speed of vehicle front pedestrian movement in real time, and the signal transmission both detected is to micro-control unit, micro-control unit judges this pedestrian according to both signals and whether can enter hazardous location (hazardous location refers to the moving velocity with the moving velocity of current automobile and pedestrian, if under braking deceleration situation do not taked by automobile, automobile will strike pedestrian), if, micro-control unit sends a signal to speech prompting system, voice message chaufeur slows down, if after voice message second time, chaufeur does not take brake measure immediately, then micro-control unit sends a signal to abs braking system immediately, automatic startup abs braking operation is to make car deceleration, when micro-control unit judges that pedestrian leaves hazardous location, issue a signal to abs braking system, stop abs braking operation.
As preferably, ultrasonic radar and speed sensor be close in pairs be one by one arranged in automobile front bumper and front left and right fender guard on, front bumper is provided with at least three ultrasonic radars and at least three speed sensors, left and right daughter board is respectively arranged with at least one ultrasonic radar and at least one speed sensor.Ultrasonic radar and speed sensor form complete detection area at automotive front end, accurately can detect the Distance geometry moving velocity of vehicle front pedestrian.
As preferably, speech prompting system comprises loud speaker, speech selection panel and voice message controller, and the electrical connection of voice message controller micro-control unit, loud speaker and speech selection panel, loud speaker and speech selection panel are arranged on instrument carrier panel.
As preferably, micro-control unit is also electrically connected with light prompt system, light prompt system comprises warning light and light prompt controller and light variable controller in car, light prompt controller electrical connection micro-control unit and Che Nei warning light, light variable controller electrical connection micro-control unit and headlight.While carrying out voice message, remind chaufeur by warning light flicker in car, prevent the noisy chaufeur that causes in car from cannot hear voice message sound.Meanwhile, light variable controller control headlight carries out nearly distance light change light thus reminds pedestrian to dodge in time.
Therefore, the present invention has following beneficial effect: (1), by detecting pedestrian and automobile relative position and relative velocity, reminds chaufeur braking to dodge in time; (2) after prompting twice, can autobrake, Accident prevention occurs; (3) can the nearly distance light of auto-changing, remind pedestrian to dodge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1 car speed sensor; 2 ultrasonic radars; 3 speed sensors; 4 micro-control units; 5 speech prompting systems; 501 loud speakers; 502 speech selection panels; 503 voice message controllers; 6ABS brake system; 7 light prompt systems; Warning light in 701 cars; 702 light prompt controllers; 703 light variable controllers.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
Embodiment: as shown in Figure 1, a kind of vehicle-mounted pedestrian protection system of the present invention, comprises car speed sensor 1, ultrasonic radar 2, speed sensor 3, micro-control unit 4, speech prompting system 5 and abs braking system 6.Car speed sensor 1 step is placed on automotive wheel, on the front bumper that ultrasonic radar 2 and speed sensor 3 are arranged in automobile and front left and right fender guard, ultrasonic radar 2, speed sensor 3, speech prompting system 5 and abs braking system 6 are electrically connected with micro-control unit 4 respectively.
Ultrasonic radar 2 and speed sensor 3 be close in pairs be one by one arranged in automobile front bumper and front left and right fender guard on, front bumper is provided with three ultrasonic radars 2 and three speed sensors 3, left and right daughter board is respectively arranged with a ultrasonic radar 2 and a speed sensor 3.
