COMPONENT PARTS
Electrically-driven Intelligent Brake Unit
INFOID:0000000010122981
Integrates the control module, master cylinder, and brake booster,
and it controls the fluid pressure that is sent to the ABS actuator and
electric unit (control unit).
CONTROL MODULE
• Controls the fluid pressure that is applied to the brake calipers, based on the signals from each sensor and
unit.
• Performs cooperative regenerative brake control.
• When a malfunction is detected, the system enters fail-safe mode.
MASTER CYLINDER
• Generates brake fluid pressure according to the amount of piston movement.
• The fluid pressure generated by the master cylinder is sent to the ABS actuator and electric unit (control
unit).
BRAKE BOOSTER
• Contains a motor and generates boost force according to the amount that the brake pedal is depressed and
the amount of cooperative regenerative brake control.
• Uses the boost force to generate fluid pressure in the master cylinder.
