Network carries out communication and diagnostic function.
In the implementation of the present invention, the inventor finds that the existing technology has at least the following problems: regulation clear stipulaties
Passenger car must be equipped with urgent/emergency brake to ensure the function of having brake when driving a vehicle brake system non-functional.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of redundancy link that ibooster is also included in emergency braking,
Further decrease the more redundant emergency brake methods of automobile of brake fade probability.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that: a kind of more redundant emergency brakes of automobile
Method, comprising:
Ibooster, that is, electronic vacuum booster, ESP, that is, electronics body stabilization system, EPB, that is, electronic brake system；
Braking method includes the following steps:
1) brake request signal gives ibooster, ESP and EPB system by CAN network, that is, automobile control bus simultaneous transmission
System；
2) it in the trouble-free situation of ibooster system, completes to brake by ibooster；Ibooster system is faulty
In the case of, then execute the 3) step；
3) CAN network transmits a signal to ESP system, in the trouble-free situation of ESP system, completes to brake by ESP system；
In the faulty situation of ESP system, then the 4) step is executed；
4) CAN network transmits a signal to EPB system, in the trouble-free situation of EPB system, completes to brake by EPB system.
Above-mentioned the 2) in step, in the case that ibooster system fault-free can complete brake, ibooster system transmission letter
Number give ESP and EPB system, so that ESP and EPB system is not executed brake.
Above-mentioned the 3) in step, and in the case that ESP system fault-free can complete brake, ESP system transmits signal EPB system,
EPB system is set not execute brake.
Above-mentioned the 2) in step, and ibooster active boost completes four wheel brakes.
Above-mentioned the 3) in step, and ESP system executes four-wheel active boost and completes brake.
Above-mentioned the 4) in step, and EPB system row rear-wheel clamps, to complete brake.
A technical solution in above-mentioned technical proposal has the following advantages that or beneficial effect, ibooster is also included in tight
The redundancy link suddenly braked, further decreases brake fade probability.
Detailed description of the invention
Fig. 1 is the control principle drawing of the more redundant emergency brake methods of automobile provided in the embodiment of the present invention；
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Referring to Fig. 1, a kind of more redundant emergency brake methods of automobile, comprising:
Ibooster, that is, electronic vacuum booster, ESP, that is, electronics body stabilization system, EPB, that is, electronic brake system；
Braking method includes the following steps:
1) brake request signal gives ibooster, ESP and EPB system by CAN network, that is, automobile control bus simultaneous transmission
System；
2) it in the trouble-free situation of ibooster system, completes to brake by ibooster；Ibooster system is faulty
In the case of, then execute the 3) step；
3) CAN network transmits a signal to ESP system, in the trouble-free situation of ESP system, completes to brake by ESP system；
In the faulty situation of ESP system, then the 4) step is executed；
4) CAN network transmits a signal to EPB system, in the trouble-free situation of EPB system, completes to brake by EPB system.
Above-mentioned the 2) in step, in the case that ibooster system fault-free can complete brake, ibooster system transmission letter
Number give ESP and EPB system, so that ESP and EPB system is not executed brake.
Above-mentioned the 3) in step, and in the case that ESP system fault-free can complete brake, ESP system transmits signal EPB system,
EPB system is set not execute brake.
Above-mentioned the 2) in step, and ibooster active boost completes four wheel brakes.
Above-mentioned the 3) in step, and ESP system executes four-wheel active boost and completes brake.
Above-mentioned the 4) in step, and EPB system row rear-wheel clamps, to complete brake.
When executing emergency/emergency braking request, brake request signal is given by CAN network simultaneous transmission
Ibooster, EPB and ESP system.Priority are as follows: complete by ibooster active boost under ibooster system non-failure conditions
At four wheel brakes, ESP system is transferred to if ibooster is faulty；Under ESP system non-failure conditions, executed by ESP system
Four-wheel active boost completes brake request (slow down larger, about 6m/s2)；If in the faulty situation of ESP system, ESP system is certainly
Body can not be completed active boost function, then executes rear-wheel by EPB system and clamp (slow down smaller, about 2.5m/s2), to complete to stop
Vehicle request.
The present invention and traditional fit structure compare, and are being equipped with ibooster (electronic vacuum booster), EPB (electronic parking
Braking system), on the vehicle of ESP (electronics body stabilization system) system, only software logic has made subtle change, further
The redundancy properties of system are improved, security level is improved；High-volume is easy to promote.
After above-mentioned scheme, ibooster is also included in the redundancy link of emergency braking, braking is further decreased and loses
Imitate probability.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
