Description

A kind of vehicle automatic emergency brake method

Technical field

The invention belongs to emergency brake of vehicle control technology fields, and in particular to a kind of vehicle automatic emergency brake method.

Background technique

The braking system of vehicle generally comprises service braking system and parking braking system, wherein parking braking scheme root It is divided into traditional mechanical type parking brake and electronic brake according to braking energy source difference.

Electronic brake includes two technology paths of wire drawing type electronic parking and the parking of clamp integrated type electrical;Wire drawing type Electronic parking replaces traditional parking handle using motor, but still executes parking using two wire drawings;Clamp integrated form Electronic parking integrates parking motor with clamp, and when parking directly controls parking motor and executes parking.Mechanical type parking brake system For system in emergency braking, only with the mode of pull-up parking brake, braking process is easy to happen rear lock.But works as and rain or snow When, if activation anti-lock brake system is easy due to the relatively more sliding vehicle emergency braking at this time in road surface, although wheel can prevent from embracing Extremely, promote the braking ability of vehicle, but vehicle may due to anti-lock brake system influence and be unable to reach dry road The desired deceleration being arranged under face, so that rear-end impact accident occur.

Summary of the invention

The purpose of the present invention is to provide a kind of vehicle automatic emergency brake methods, to solve to propose in above-mentioned background technique The problem of.

To achieve the above object, the invention provides the following technical scheme: a kind of vehicle automatic emergency brake method, including it is System initialization, information collection, environmental information, vehicle operation, distance-sensor and speed detector, the system initialization pass through The information of information acquisition module is acquired, the distance-sensor and speed detector are by the data on information acquisition module It is read out, the distance-sensor and speed detector transmit a signal to danger judgement module, the danger judgement module Its signal is judged, and when judging result is dangerous, alarm system is sent a signal to by danger judgement module, it is described Alarm system sends a signal to motor vehicle braking system, and the motor vehicle braking system judges, and vehicle is carried out braking processing, The danger judgement module adjust the distance inductor and speed detector transmitting signal judged, when danger judgement resume module Signal when being safe, signal is subjected to output return, signal is delivered to information acquisition module by the danger judgement module, so Signal later is being judged by information acquisition module afterwards, the information acquisition module to vehicle run and environmental information into Row acquisition transmitting, the danger judgement module loop to determine signal.

Preferably, the vehicle body headstock front of vehicle is arranged in the range sensor, and the velocity sensor is arranged in vehicle Wheel on.

Preferably, the braking system includes vehicle power supply, and the body tail of the vehicle is arranged in the vehicle power supply.

Technical effect and advantage of the invention: the vehicle automatic emergency brake method, by the way that distance-sensor, speed is arranged Then detector, setting selection decision block are issued alarm, so that braking by detecting to the case where its front in advance System is operated, and the generation to crash is avoided.

Detailed description of the invention

Fig. 1 is structural system schematic diagram of the invention.

Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

The present invention provides a kind of vehicle automatic emergency brake methods as shown in Figure 1, including system initialization, information to adopt Collection, environmental information, vehicle operation, distance-sensor and speed detector, the system initialization pass through to information acquisition module Information be acquired, the data on information acquisition module are read out by the distance-sensor and speed detector, described Distance-sensor and speed detector transmit a signal to danger judgement module, and the danger judgement module sentences its signal It is disconnected, and when judging result is dangerous, alarm system is sent a signal to by danger judgement module, the alarm system is by signal It is sent to motor vehicle braking system, the motor vehicle braking system judges, and vehicle is carried out braking processing, the danger judgement mould Block adjust the distance inductor and speed detector transmitting signal judged, when the signal of danger judgement resume module be safety When, signal is subjected to output return, signal is delivered to information acquisition module, then adopted by information by the danger judgement module Collection module judges that signal later, the information acquisition module is run to vehicle and environmental information is acquired transmitting, The danger judgement module loops to determine signal.

Specifically, the vehicle body headstock front of vehicle is arranged in the range sensor, the velocity sensor is arranged in vehicle Wheel on.

Specifically, the braking system includes vehicle power supply, the body tail of the vehicle is arranged in the vehicle power supply.

The vehicle automatic emergency brake method is detected when vehicle is run by vehicle operation and environmental information side, Send the signal to information collection, then by distance-sensor and speed detector, the speed of service and vehicle to vehicle it Between distance carry out thoroughly, to alarm it, when alarm sounded, then start braking system, dynamic braking, thus Vehicle is subjected to locking, so that avoiding that the collision between vehicle occurs, to avoid the generation of accident.

Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention, Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features, All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention Within protection scope.
