4. HYDRAULIC CIRCUIT DIAGRAM
1) Hydraulic Circuit of ABS
The vehicle equipped only with the ABS controls the wheel’s braking force using three 3-
channel 4-sensor method. The front wheels that are the primary circuit of the brake system is
composed of two wheel speed sensors and two channel valves system with two inlet valves and two
outlet valves. The rear wheels that are the secondary circuit of the brake system is composed of two
wheel speed sensors, one inlet valve and one outlet valve. This system is similar to the one from the
previous model.

2) ABS Circuit Per ABS Operation Range
▶Hydraulic Pressure Circuit when ABS is Not Operating
The hydraulic pressure in the master cylinder increases through the vacuum booster and it is delivered
to the wheel via the normal open inlet valve. At this moment, the normally-closed outlet valve is closed.
The speed of the wheel that hydraulic pressure is delivered reduces gradually.
▶No Hydraulic Pressure Circuit when ABS is Operating
As hydraulic pressure on each wheel increases, the wheel tends to lock. In order to prevent the wheel
from locking, the hydraulic valve modulator operates the inlet valve control solenoid to close the inlet
valve and stop the hydraulic pressure increases. At this moment, the outlet valve is closed. This
procedure helps the wheel to maintain a stable hydraulic pressure.

▶Pressure Decreases in the Circuit when ABS is Operating
Even when the hydraulic pressure on each circuit is stable, the wheel can be locked as the wheel
speed decreases. This is when the ABS ECU detects the wheel speed and the vehicle speed and
gives the optimized braking without locking the wheels. In order to prevent from hydraulic pressure
increases, the inlet valve is closed and the outlet valve is opened. Also, the oil is sent to the low
pressure changer and the wheel speed increases again. The ABS ECU operates the pump to circulate
the oil in the low pressure chamber to the master cylinder. This may make the driver to feel the brake
pedal vibration and some noises.
▶Pressure Increases in the Circuit when ABS is Operating
As the wheel speed increases, the inlet valve opens and the wheel’s pressure increases due to
the master cylinder pressure. The oil in the low pressure chamber circulates to the wheel by the pump
and the wheel speed decreases as the hydraulic pressure at wheel increases. This operation
continues repetitively until there are no signs that the ECU is locking the wheels. When the ABS
hydraulic pressure control takes place, there may be some vibration and noises at the brake pedal.
