Anti-lock Brake SYstem (ABS)
when the brake pedal is depressed during driving, the wheels can lock before the vehicle comes to a stop. In such an event.
the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of the vehicle is reduced if the
rear wheels are locked, creating an extremely unstable condition. The ABS precisely controls the slip rate o{ the wheels to
ensUre maximum grip force from the tires, and it thereby ensures maneuverbiIity and stabiIity of the vehicIe.
The ABS calculates the slip rate of the wheels based on the vehicle speed and the wheel speed. then it controls the brake
fluid oressure to attain the target slip rate

Features/Construction (cont'd)
ABS Modulatol
The ABS modulator consists of the inlet solenoid valve, outlet solenoid valve, reservoir, pump, pump motor and the
damping chamber.
The modulator reduces the caliper fluid pressure directly. lt is a circulating-type modulator because the brake fiuid circulates
through the caliper, reservoir and the master cylinder.
The hydraulic control has three modes: pressure reduction, pressure retaining and pressure intensiiying
The hvdraulic circuit is the independent four channel-type, one channel tor each wheel'
L-__
RF LR
Pressure intensifying mode: Inlet valve open, outlet valve closed
Master cvlinder fluid is pumped out to the caliper.
Inlet valve closed, outlet valve closed
Caliper fluid is retained by the inlet valve and outlet valve.
lnlet valve closed, outlet valve open
Caliper fluid flows through the outlet valve to the reservolr'
When starting the pressure reduction mode, the pump motor is ON.
When stopping ABS operation, the pump motor is OFF.
The reservoir fluid is pumped out by the pump, through the damping chamber, to the master
cylinder.
