Detailed description of the invention
In order to understand the technical characterstic of explanation this programme, below by a specific embodiment, and combine its accompanying drawing
This programme is illustrated.
One of the present invention be used for Vehicular intelligent brake system, this system by probe unit module, data processing unit module,
Control unit module and brake performance element module composition, as shown in Figure 1；
Described probe unit module is responsible for collecting the information on road surface, including the real-time speed of vehicle and preceding object thing
Distance, it is achieved the vehicle perception to environment, provides data for data processing unit module；The equipment that described detector uses has
Velocity sensor, infrared sensor and ultrasonic range finder sensor, plurality of devices is applied in combination, it is ensured that the real-time of data and can
By property；Described probe unit module needs the data collected to include speed, obstacle distance, highly, translational speed；
Described data processing unit module is the speed collecting detector and range data storage and calculates, and endangers
Danger target recognition, if as in figure 2 it is shown, such as risk object, passing to control unit module the most immediately by the signal of telecommunication；Described danger
Danger target recognition strategy: as in figure 2 it is shown, the mesh in having five points of A, B, C, D and E to represent probe unit module investigative range in figure
Standard type, represents five kinds of situations respectively.Wherein, A is in I district, vertically shifts to vehicle with certain speed；B is in IIth district, and (car is just
Front), move on to the right with certain speed；C is in IIIth district, equally to right travel；D is in IIth district, without initial velocity；E
It is in I district, and Vehicle Speed is in opposite direction；The judgment mode taked for the object in I district is that it is with or without speed to the right
Component, such as A and E, it is clear that A has E not have, A is risk object, and E is not；For II district's object, D is with not having the most to the right
Speed, but it is in the dead ahead that vehicle travels, thus be risk object；As for the judgement of B, need B across an overall width
Required time and vehicle arrive B point position and compare, if the former is big, are defined as risk object, otherwise, B benign target；
For III district's object, then consistent with the decision principle in I district, except for the difference that: whether object has component velocity to the left, for C
Obviously do not have, because of rather than risk object；
The signal that described control unit module is come according to data processing unit transmission, formulates decision-making action, thus realizes
Intelligent braking, system is reported to the police in the process；Risk object has been formulated 3 kinds of brake riggings by described control unit module
Strategy, is straight braking, index braking, logarithm braking, it is possible to achieve pure strategy or the braking of multiple strategy combination respectively, permissible
The effective abrasion reducing friction plate, protects brake；Wherein, described straight braking, index braking and logarithm braking refers to
The mode of loading brake force；Control unit module receives the signal of telecommunication of the risk object from data processing unit module
After, control system carries out early warning, according to I district and II district's information, takes braking decision-making as shown in Figure 3, and according to distance and car
The speed advanced, chooses suitable parameter, and passes it to brake system driver element；
Described brake performance element module is the performance element that brake is the most static, reception control unit modular telecommunications number,
And then drive the execution units such as hydraulic cylinder to carry out compression motion；Described warning system includes two parts: Part I is by raising
Vehicle drivers reminded by sound device, and Part II reminds vehicle below by taillight；
Described system operational process, as shown in Figure 4, step is as follows:
Step (1), vehicle launch, system starts to initialize, including equipment test and correction, Memory Allocation and basic parameter
Configuration；
Step (2), detector data read, and within the time that system is specified, obtain the relevant information of preceding object thing, bag
Include speed, obstacle distance, highly, translational speed；
Step (3), it is identified barrier whether being risk object, as if not returning to step (2), if as will
The signal of telecommunication passes to control unit module, formulates braking strategy, and carries out early warning, passes information to vehicle drivers and car below
?；
The signal of telecommunication is passed to brake actuating mechanism driver element module by step (4), control unit so that it is drive hydraulic cylinder
It is braked device brake command Deng actuator.
The present invention is not limited in above-mentioned detailed description of the invention, and those of ordinary skill in the art are in the essential scope of the present invention
The change inside made, retrofit, add or replace, also should belong to protection scope of the present invention.
