Description
Technical field
The present invention relates to a kind of warning lamp drive circuits.
Background technique
Abs braking anti-lock braking system is exactly that wheel will not locking in braking.It is envisioned that when driver's emergency braking
After quick brake pedal, front-wheel will not locking, steering capability still exists, that can just take measures in braking completely
Avoid the danger in front.If rear-wheel will not locking, break away and whipping also there will not be, the control of vehicle body is still deposited
Dangerous possibility will reduced.By the simple analysis of front, the most important function of ABS is not intended to shorten system in fact
Dynamic distance, and be to be able to keep the directional stability of auto in Braking as far as possible.When anti-blocking brake system works, wheel
With the friction category rolling friction on road surface, this can make full use of the maximum adhesion power between wheel and road surface to be braked, to mention
High braking deceleration shortens braking distance, but most important or guarantee road holding.With regard to suitable when ABS works
In carrying out a brake with very high frequency, brake pedal is then in case of emergency stepped on, is certain to feel that brake pedal is trembleing, together
When can also hear master cylinder issue " rattling away " sound, this is that ABS is being worked normally.Since master cylinder is in continuous adjustment system
Dynamic pressure, to have continuous feedback force to brake pedal.EBD is actually the miscellaneous function of ABS, is the control electricity in ABS
Increase a control software in brain, mechanical system is completely the same with ABS.It is effective supplement of ABS system, general and ABS
The effect of being applied in combination, ABS can be improved.
When emergency braking occurs, EBD, can be according to the weight and pavement conditions of vehicle body, before automatic before ABS effect
The sliding ratio for comparing rear tyre is removed on the basis of wheel, when such as realizing that this difference degree must be adjusted, brake oil hydraulic system will
Adjustment reaches the oil pressure of rear-wheel, more to be balanced and be distributed closer to Utopian brake weight.When brake, vehicle four
The brake callipers of a wheel can act, and vehicle is stopped.But since pavement behavior has variation, in addition vehicle weight when slowing down
The transfer of the heart, four road holdings between wheel and ground will be different.Traditional brake system can be averaged master cylinder
Strength is distributed to four wheels.From the foregoing, such utilization benefit distributed and do not meet brake weight.EBD system just by
Invention is to make optimal application for brake weight.The function of EBD is exactly the moment in automobile brake, and supercomputing goes out four tires
Due to friction value caused by adhering to difference, brake apparatus is then adjusted, keeps it high during exercise according to the program of setting
Velocity modulation is whole, reaches the matching of brake force Yu frictional force (tractive force), to guarantee the steady and safe of vehicle.When emergency brake wheel
In the case where locking, EBD has just balanced effective ground grip of each wheel before ABS movement, can prevent out
Existing whipping and sidesway, and shorten automobile brake distance.
Existing ABS (anti-lock braking system in automobiles) and EBD (braking force distribution system) input signal and emergency warning lamp drive
It is dynamic to will appear following situations: disconnection function: ABS (anti-lock braking system in automobiles) and EBD (braking force distribution system) input letter
Number with emergency warning lamp drive module formed open circuit phenomenon can bring erroneous judgement to driver in this case, be mistakenly considered input signal
It is state that is low, causing the output of emergency warning lamp drive module that indicator light is made to be in extinguishing.Given this situation, if (automobile is antilock by ABS
Dead braking system) and EBD (braking force distribution system) faulty generation, indicator light cannot be fed back to, driver is caused to be mistaken for
Normal situation.In addition, in the situation that goes offline, even if ABS (anti-lock braking system in automobiles) and EBD (braking force distribution system) control
Unit processed does not have failure problems, can not Real-time Feedback give driver's control circuit fault condition.
Power down function: electricity is controlled in ABS (anti-lock braking system in automobiles) and EBD (braking force distribution system) control route
The power supply on road does not know the case where what reason leading to system cut-off in, in this case, it is also desirable to emergency warning lamp drive module
Driving indicator light is lighted, reminder alerting function.It is anti-when driver is in emergency brake because under power-down conditions
Locking causes vehicle the danger of safety occur, needs to start ABS system at this time, but ABS system control unit at this time is that do not have
Power supply, the function can not be started, will lead to vehicle in the danger of emergency brake (locking).
