Description
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.
