Operation Description
WARNING: This page is about a different car, the 2019 Infiniti Q50. However, it is still accessible from the selected car via links, so may be relevant.
- The ICC sensor measures the distance from the vehicle ahead and transmits the ICC sensor signal to the ADAS control unit.
- The lame 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 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 unit 2 and sounds the buzzer.
- Transmits the meter display signal to the combination meter and displays the vehicle ahead indicator/FEB warning.
- Transmits the accelerator pedal feedback force signal to the accelerator pedal actuator and moves the accelerator pedal upward to assist the driver to release the accelerator pedal.
- 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 ICC brake hold relay drive signal to the ICC brake hold relay and turns ON the stop lamp.
NOTE:
- ON/OFF of FEB/PFCW system is performed with the integral switch.
- When the ignition switch turns is turned from OFF to ON, the system is automatically activated even if it is OFF.
- The FEB system operates under the following conditions.
- The FEB 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)
- Setting of FEB is performed in synchronization with the log-in function of on-board personal assistant. For details of the log-in function, refer to System Description .
Operation Condition
ADAS control unit performs the control when the following conditions are satisfied.
- When the FEB/PFCW 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 FEB 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 ICC sensor area of the front bumper 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)
