Row signal realizes an one-key emergent braking function.
The working principle of the present embodiment is as follows:
When sensor collects vehicle operation data, brake system control unit exports control signal according to the actual situation
The rear-end collision because caused by driver pedal force is insufficient or maloperation is effectively avoided to brake pedal, is thrusted into and other is handed over
Interpreter's event；If brake pedal executes control information, i.e., expression driver's brake pedal, braking light switch closure indicate
Vehicle line control brake system is working properly, then brake system control unit passes through the first connecting pin to spare control at regular intervals
Unit processed sends a pulse validation signal, standby control unit since second connection end becomes low level from high level i.e.
This pulse validation signal is received, standby control unit does not work；If brake pedal is not carried out control information, that is, indicate to drive
The non-brake pedal of member, braking light switch is not closed, indicates that vehicle line control brake system breaks down, then braking system controls
Unit will not send pulse validation signal to standby control unit by the first connecting pin, and standby control unit does not have twice in succession
Pulse validation signal is received, standby control unit can be driven flicker of fault indicating lamps to be reminded by indicator light connecting pin and be driven
Member is note that provide a high level to control terminal according to braking light switch signal simultaneously, and triode ON, automobile power source pass through at this time
The oil inlet solenoid valve that triode is crossed to the near front wheel, off-front wheel, left rear wheel and off hind wheel is powered, the conducting of braking system inflow pipeline,
High-pressure brake liquid enters four wheel cylinders, realizes car emergency braking.
Backup power source anode is connected with automobile power source anode, and under normal circumstances, automobile power source charges to backup power source, standby
It is in sufficient electricity condition with power supply, causes automobile power source to disconnect if automobile collides, feeder ear is passed through by backup power source at this time
It powers to standby control unit.Since automobile power source disconnects, vehicle line control brake system cisco unity malfunction, standby control unit
First connecting pin does not receive pulse validation signal, therefore reinstates emergency brake function, and providing a high level to control terminal makes
Triode ON, by triode to the oil inlet solenoid valve power supply of four wheels, braking system inflow pipeline is connected backup power source,
High-pressure brake liquid enters four wheel cylinders, realizes car emergency braking.Meanwhile standby control unit is issued by indicator light connecting pin
Pulse signal drives flicker of fault indicating lamps, and driver is reminded to pay attention to.
Used herein a specific example illustrates the principle and implementation of the invention, and above embodiments are said
It is bright to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, foundation
Thought of the invention, there will be changes in the specific implementation manner and application range.In conclusion the content of the present specification is not
It is interpreted as limitation of the present invention.
