DYNAMIC STABILITY CONTROL/ROLL STABILITY CONTROL

DSC/RSC HU/CM CONSTRUCTION

• A high reliability, reduced size and weight
dynamic roll stability control (DSC)/roll stability
control (RSC) hydraulic unit (HU)/control module
CM, integrating both the DSC/RSC HU and the
DSC/RSC CM, has been adopted.

DSC/RSC HU PART FUNCTION

• According to dynamic stability control (DSC)/roll stability control (RSC) control module (CM) signals, the DSC/
RSC hydraulic unit (HU) controls (on/off) each solenoid valve and the pump motor, adjusts fluid pressure in
each caliper piston, and actuates each function (antilock brake system (ABS), electronic brakeforce distribution
(EBD), traction control system (TCS), DSC and RSC) of the DSC/RSC system.

• Adjusts the fluid pressure in each brake system according to DSC/RSC HU/CM
signals.
• Adjusts the fluid pressure in each brake system according to DSC/RSC HU/CM
signals.
• Switches the brake hydraulic circuits during and according to normal braking,
ABS and EBD control, TCS control and DSC control, RSC control.
• Switches the brake hydraulic circuits during and according to normal braking,
ABS and EBD control, TCS control and DSC control, RSC control.
• Temporarily stores brake fluid from the caliper piston to ensure smooth
pressure reduction during ABS and EBD control, TCS control and DSC control,
RSC control.
• Returns the brake fluid stored in the reservoir to the master cylinder during ABS
and DSC control, RSC control.
• Increases brake fluid pressure and sends brake fluid to each caliper piston
during TCS control and DSC control, RSC control.
• Operates the pump according to DSC/RSC HU/CM signals.
