Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by a specific embodiment, and its attached drawing is combined
This programme is illustrated.
It is of the invention a kind of to be used for Vehicular intelligent brake system, the system by probe unit module, data processing unit module,
Control unit module and brake performance unit module composition, as shown in Figure 1；
The probe unit module is responsible for collecting the information on road surface, real-time speed and front obstacle including vehicle
Distance realizes perception of the vehicle to environment, provides data for data processing unit module；The equipment that the detector uses has
Velocity sensor, infrared sensor and ultrasonic range finder sensor, plurality of devices are applied in combination, ensure that data real-time and can
By property；It includes speed, obstacle distance, height, movement speed that the probe unit module, which needs the data collected,；
The data processing unit module is the speed collected to detector and range data storage and calculates, and is endangered
Dangerous target identification, as shown in Fig. 2, electric signal is then passed to control unit module immediately such as if risk object；The danger
Dangerous target identification strategy: as shown in Fig. 2, there is five points of A, B, C, D and E to indicate the mesh in probe unit module investigative range in figure
Standard type respectively represents five kinds of situations.Wherein, A is in the area I, vertically shifts to vehicle with certain speed；B is in IIth area, and (vehicle is just
Front), it is moved on to the right with certain speed；C is in IIIth area, equally to right travel；D is in IIth area, no initial velocity；E
It is contrary in the area I and Vehicle Speed；For the judgment mode that the object in the area I is taken be its whether there is or not speed to the right
Component, such as A and E, it is clear that A has E not have, and A is risk object, and E is not then；For II area's object, D is with not to the right
Speed, but its front for being in vehicle driving, thus be risk object；As for the judgement of B, need B across a vehicle width
Required time and vehicle reach B point position and are compared, if the former is big, risk object are defined as, conversely, the not dangerous target of B；
It is for III area's object, then consistent with the decision principle in the area I, unlike: whether object has component velocity to the left, for C
Obviously do not have, because rather than risk object；
The control unit module according to data processing unit transmitting come signal, formulate decision movement, to realize
Intelligent braking, system is alarmed in the process；The control unit module has formulated 3 kinds of brake riggings to risk object
Strategy is straight braking, index braking, logarithm braking respectively, pure strategy or the braking of a variety of strategy combinations may be implemented, can be with
The effective abrasion for reducing friction plate, protects brake；Wherein, the straight braking, index braking and logarithm brake finger
Load brake force mode；Control unit module receives the electric signal of the risk object from data processing unit module
Afterwards, control system carries out early warning and takes braking decision as shown in Figure 3 according to the area I and II area's information, and according to distance and vehicle
The speed of traveling chooses suitable parameter, and passes it to brake system driving unit；
The brake performance unit module is to brake to static execution unit, reception control unit modular telecommunications number,
And then the execution units such as driving hydraulic cylinder carry out compression motion；The alarm system includes two parts: first part is by raising
Sound device reminds vehicle drivers, and second part reminds subsequent vehicle by taillight；
The system operational process, as shown in figure 4, steps are as follows:
Step (1), vehicle launch, system start to initialize, including equipment test and correction, Memory Allocation and basic parameter
Configuration；
Step (2), detector data are read, and within the time that system is specified, obtain the relevant information of front obstacle, are wrapped
Include speed, obstacle distance, height, movement speed；
Step (3) identify whether being risk object to barrier, such as if not returning to step (2), if as will
Electric signal passes to control unit module, formulates braking strategy, and carry out early warning, passes information to vehicle drivers and below vehicle
?；
Electric signal is passed to brake actuating mechanism driving uinit module by step (4), control unit, makes its driving hydraulic cylinder
Equal executing agencies carry out brake order.
The present invention is not limited in above-mentioned specific embodiment, and those of ordinary skill in the art are in essential scope of the invention
The variations, modifications, additions or substitutions inside made, also should belong to protection scope of the present invention.
