Operation Description

Calculate the distance and relative speed with the vehicle ahead by ICC sensor integrated unit. Control the accelerator pedal actuator and brake booster control unit based on the calculated value via ITS communication.

When brake operation by driver is required	The system alerts the driver by a warning chime and blinking the vehicle ahead detection indicator. If the driver is depressing the accelerator pedal after the warning, the system moves the accelerator pedal upward to assist the driver to switch to the brake pedal.

DECELERATION CONTROL REFERENCE CHART

Deceleration control	It transmits the brake fluid pressure command signal to the brake booster control unit via ITS communication and performs the brake control.
Accelerator pedal actuation control	It transmits the accelerator pedal feedback force control signal to the accelerator pedal actuator via ITS communication and controls the accelerator pedal in the upward direction.

Operation Condition

ICC sensor integrated unit performs the control when the following conditions are satisfied.

When the DCA switch is turned to ON.
When the brake pedal is not depressed.
When the vehicle speed is above approximately 5 km/h (3 MPH).
When the vehicle ahead is detected.
When the ICC system is not set.

No Operation Condition

The ICC sensor integrated unit is not operate when the system is under any conditions of the no operation condition.

When the brake pedal depressed.
When the ICC system is set.
When the system judges that the vehicle comes to a standstill by the system control.
When the vehicle ahead is not detected.

Operation Cancellation Condition

The ICC sensor integrated unit cancels the operation when the system is under any conditions of the operation cancellation condition.

When the DCA switch is turned to OFF.
When the system malfunction occurs.
When ABS or VDC (including the TCS) operates.
When the VDC is turned OFF.
When the snow mode switch is turned ON.
When driving into a strong light (i.e., sunlight).
When the ICC sensor integrated unit body window is dirty and the measurement of the distance between the vehicles becomes difficult.

Operation At The Driver Operation

Give priority to the driver operation in the following situation.

When the accelerator pedal is depressed again.
When the brake pedal is depressed.
