COMPONENTS DESCRIPTION

Component	Vehicle-to-vehicle distance control mode	Conventional (fixed speed) cruise control mode	Brake assist (with preview function)	Description
ICC sensor integrated unit	x	x	x	Controls vehicle distance by operating electric throttle control actuator based on that sensor signals and CAN communication data. Controls vehicle distance by transmitting deceleration degree commandment value signal to ABS actuator and electric unit (control unit) when deceleration with brake is needed. Irradiates laser beam, and receives reflected laser beam to measure distance from preceding vehicle.
ECM	x	x	x	Transmits accelerator pedal position signal, ICC brake switch signal, stop lamp switch signal and ICC steering switch signal to ICC sensor integrated unit through CAN communication.
ABS actuator and electric unit (control unit)	x	x	x	Transmits vehicle speed signal (wheel speed) and stop lamp switch signal to ICC sensor integrated unit through CAN communication. Receives deceleration degree commandment value signal from ICC sensor integrated unit, and controls brake fluid pressure with the ABS motor.
BCM	x	-	-	Transmits front wiper request signal to ICC sensor integrated unit through CAN communication.
TCM	x	x	-	Transmits gear position signal and output shaft revolution signal to ICC sensor integrated unit through CAN communication.
Unified meter and A/C amp.	x	x	x	Receives meter display signal, ICC warning lamp signal and buzzer output signal from ICC sensor integrated unit through CAN communication.
ICC brake switch	x	x	x	Transmits operating signal to ECM when depressing brake pedal. ICC sensor integrated unit cancels cruise system at driver's brake operation.
Stop lamp switch	x	x	x	Transmits operating signal to ECM and ABS actuator and electric unit (control unit) when depressing brake pedal. ICC sensor integrated unit cancels cruise system at driver's brake operation.
