LDP System Control Description

LDP system is controlled by lane camera unit and LDP controller [ABS actuator and electric unit (control unit)].
NOTE:
LDP controller is integrated in the ABS actuator and electric unit (control unit).
Lane camera unit monitors lane markers of the traveling lane. It transmits the detected lane condition signal to ABS actuator and electric unit (control unit) via CAN communication.
ABS actuator and electric unit (control unit) detects vehicle conditions depending on each signal.
Combination meter turns the lane departure warning lamp and LDP ON indicator lamp ON/OFF according to the signals from the lane camera unit via CAN communication (through unified meter and A/C amp.).
When ABS actuator and electric unit (control unit) judges vehicle deviation from the traveling lane, it controls following actions.
- Requests warning to the lane camera unit via CAN communication to alert the driver. And then lane camera unit controls the lane departure warning buzzer and it requests the lane departure warning lamp activation to combination meter.
- Calculates the necessary yaw moment. And then it controls the brake pressure of each wheel individually to generate the intended movement.
ICC sensor integrated unit receives signals from the AV control unit and the ECM and transmits an LDP ON signal to the ABS control unit.

LDP OPERATING CONDITION

LDP ON indicator lamp: ON
NOTE:
- When the LDP system setting on the navigation screen is ON.
- Warning systems ON indicator is OFF.
Vehicle speed: approximately 70 km/h (45 MPH) or more

NOTE:

For details of LDP system operating conditions, refer to normal operating condition DESCRIPTION .
