Magnet valve and scavenge oil pump, the control instruction of they reception control units also works；Control unit is also passed through with control unit of engine
CAN-H Yu CAN-L carries out communication, and can be controlled electronic throttle as desired by control unit of engine.
The composition and working principle of hydraulic control unit is as in figure 2 it is shown, its specific works principle is as follows:
1, automobile ABS
Ignition switch closes, provides ignition signal to control unit；Step on brake pedal, control unit receives brake signal；Left
Before, before the right side, rear four wheel speed sensors left back, right provide wheel speed signal to control unit.
(1), conventional brake
When control unit is according to the wheel speed sensors non-locking of signal determining wheel, control unit gives all electromagnetic valves all no powers,
Front two-position three way magnetic valve 6 and rear two-position three way magnetic valve 27 connect the oil circuit of master cylinder 4 and each wheel liquid feed valve, each feed liquor
Valve is opened, and each liquid valve is closed, and now, brake fluid can enter into wheel cylinder from master cylinder and wheel produces braking, and control
Unit processed powers to electronic scavenge oil pump, electronic oil return air pump inoperative.
(2), automobile ABS works
When control unit according to wheel speed sensors signal determining wheel will locking time, control unit first give this wheel feed liquor
Valve is energized, and this closed electromagnetic valve, this wheel braking oil pressure no longer raise, referred to as pressurize；Such as wheel locking also further, control
Unit gives the liquid valve energising of this wheel again, and this electromagnetic valve is opened, this wheel braking oil pressure declines, and is referred to as decompression, prevents wheel
Locking, now, control unit powers to electronic scavenge oil pump, the work of electronic scavenge oil pump, by from liquid valve brake fluid blowback out
Master cylinder；When vehicle wheel rotational speed gos up, when control unit judges again the non-locking of this wheel, control unit gives this wheel electromagnetic valve all
No power, this wheel returns to conventional brake state, and brake fluid enters into wheel cylinder from master cylinder and this wheel is produced braking,
It is referred to as supercharging；Control unit constantly controls this wheel according to wheel speed sensors signal and is in optimal on-position, prevents wheel lock up.
2, automobile ASR
When ignition switch Guan Bi and ASR/ESP switch are not turned off, control unit drives according to wheel speed sensors signal determining
Wheel skid time, control unit can as desired by control unit of engine control electronic throttle reduce motor torque output or
Brake directly to this driving wheel.When needs are braked to certain driving wheel, control unit gives the two-position three way magnetic valve energising of this side,
Two-position three way magnetic valve connection master cylinder and electronic scavenge oil pump inlet oil circuit, and this electronic scavenge oil pump energising work, electronic time
Oil pump produces oil pressure and is braked to this wheel, prevents this wheel-slip.When being not required to brake to driving wheel, control unit is not given
Two-position three way magnetic valve and the electronic scavenge oil pump of this side are energized.
3, automobile ESP
When ignition switch Guan Bi and ASR/ESP switch are not turned off, control unit is according to steering wheel angle sensor, the most inclined
When Slew Rate sensor signal judges automobile deviation driving trace, certain or certain several wheels are braked by control unit automatically, with
Traval trace is modified, prevents automobile operation out of control.Control principle is similar to automobile ASR, except for the difference that automobile
All wheels can be braked by ESP, and automobile ASR only controls driving wheel.
4, each liquid feed valve is bi-bit bi-pass normally open solenoid valve, and each liquid valve is bi-bit bi-pass normally closed solenoid valve.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all the spirit and principles in the present invention it
In, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
