LANE DEPARTURE PREVENTION (LDP) SYSTEM

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.

LDP OPERATING CONDITION

• LDP ON indicator lamp: ON

NOTE:
LDW ON indicator is OFF.

• Vehicle speed: approximately 72 km/h (45 MPH) or more
NOTE:
For details of LDP system operating conditions, refer to normal operating condition
