Description
Technical field
The present invention relates to auto industry technical fields, more particularly to a kind of Automobile brake control system, auto brake system
System, automobile and automobile brake method.
Background technique
With the increasing of automobile engine power, the reduction of engine speed, the increasing of loading capacity, the quickening of speed and vehicle
The raising of mounted mass, the safety problem of running car become abnormal severe.In the prior art, the main mode of braking of automobile is still
To rely on brake disc friction catch, although the improvement of brake shoe and wheel hub brake disc frictional behaviour is to disposable braking distance
Shortening is promoted, but in the case where long-time braking, long range down hill braking and frequently braking, existing brake disc friction system
Dynamic failure is still very common.
Many advanced electronic technology such as anti-lock brake system ABS, electric brake system EBS and drive control system
When friction braking system is effective, the safety that may make friction braking system to use is greatly improved, but to such as the use of ASR
Brake temperature is excessively high and brake wear is but without help.
The braking system of current motor vehicles, executing agency are all to install friction plate on each wheel, are needing to stop
It is enabled when vehicle；But when needing to stop or slow down in such as descending driving conditions, if friction disc brake once fails,
In the case where there is no other effective deceleration measures, gently then cause any property loss, it is heavy then cause casualties.For this problem,
Shown in the technical solution as provided by the utility model patent application No. is 201620319658.3, a kind of new automobile is provided
Spare braking device, using the braking system, relative to other existing automobile standby braking systems, such as:
1, brake band is put down, by automobile in the brake system failure of automobile using the brake band that bottom of car is arranged in
Rear-wheel push down brake band to realize braking effect；
2, increase triple valve in original automobile brake system, realize that two sets of brake system control brake part；
3, using the friction block for being mounted on bottom of car, friction block generates frictional force with grabbing in braking process, plays system
The modes of braking such as dynamic effect, in fact it could happen that: brake band and friction block are easy because unbalance stress causes vapour in braking process
Vehicle brake is unstable, occurs to break away or overturn, or because of environmental conditions such as the out-of-flatnesses on ground, so that spare braking device failure etc. is asked
Topic.
The structure design for advanced optimizing existing automobile brake system, so that it is capable of providing when needing vehicle deceleration
Reliable brake force is those skilled in the art's technical problem urgently to be resolved in favor of traffic safety.
Summary of the invention
For the structure design for advanced optimizing existing automobile brake system set forth above, so that it is needing vehicle
It is capable of providing reliable brake force when deceleration in favor of traffic safety, is that those skilled in the art's technology urgently to be resolved is asked
