Operation Description
- The distance sensor (ICC sensor) measures the distance from the vehicle ahead and transmits the distance sensor (ICC sensor) signal to the ADAS control unit.
- The lane camera unit measures the distance from a pedestrian and transmits the pedestrian ahead signal to ADAS control unit.
- The ADAS control unit judges the possibility of a collision from the distance sensor (ICC sensor) signal, the pedestrian ahead signal and the vehicle speed.
- The ADAS control unit performs the following operations according to the degree of possibility of a collision.
- Transmits the driver assistance buzzer signal to the ADAS control and sounds the buzzer.
- Transmits the meter display signal to the combination meter and displays AEB warning.
- Transmits the brake fluid pressure control signal to the ABS actuator and electric unit (control unit) via chassis control module and performs the brake control
- Transmits the stop lamp request signal to BCM and turns ON the stop lamp.
NOTE:
- ON/OFF of AEB system is performed with the combination meter.
- When the ignition switch turns is turned from OFF to ON, the system is automatically activated even if it is OFF.
- The AEB system operates under the following conditions.
- The AEB system will function when the vehicle is driven at speeds of approximately 5 km/h (3 MPH) and above, and when the vehicle's speed is approximately 5 km/h (3 MPH) faster than that of the vehicle ahead. (For vehicle)
Operation Condition
ADAS control unit performs the control when the following conditions are satisfied.
- When the AEB system setting on the integral switch is ON.
- When the vehicle speed is above approximately 5 km/h (3 MPH). (For vehicle)
- When the vehicle speed is within the range of approximately 10 - 60 km/h (5 - 37 MPH). (For pedestrian)
- There is a possibility of a collision with the vehicle and pedestrian ahead.
No Operation Condition
The ADAS control unit is not operate when the system is under the conditions of the no operation condition.
- When the AEB system setting on the integral switch is OFF.
- When the vehicle and pedestrian ahead is not detected.
- When the vehicle speed is below approximately 10 km/h (5 MPH). (For pedestrian)
Operation Cancellation Condition
The ADAS control unit cancels the operation when the system is under any conditions of the operation cancellation condition.
- When the system judges that the vehicle comes to a standstill by the system control.
- When the system malfunction occurs.
- When the front grille area is dirty and the measurement of the distance between the vehicles becomes difficult. (For vehicle)
- When the view of ahead is hard is recognized due to dirt around lane camera unit of windshield. (For pedestrian)
