ELECTRONIC PARKING BRAKE
Fault finding – System operation
PRESENTATION OF THE PARKING BRAKE:
The electronic parking brake provides the following functions:
– keeps the vehicle stationary when stopped (parking brake).
– 'dynamic' emergency brake (if the main brakes fail).
– automatic braking force adjustment according to the slope (adapted application),
– electronically-assisted parking brake application when the engine is stopped (depending on configuration),
– easy start with electronically-assisted parking brake release (depending on configuration),
– manual application and release by pulling on the lever.
SYSTEM COMPONENTS AND OPERATION:
The system consists of the following components:
●Control lever with brake on indicator light.
– For applying and releasing the parking brake.
●Control unit (computer) housing an electric motor, the brake cable hooks, angle sensor and force sensor.
–The angle sensor controls locking according to the angle of the slope.
–The force sensor checks and corrects the force applied to the brakes.
●Clutch pedal position sensor to help with pulling away.
– Informs the computer of the vehicle's clutch position (the position of the pedal enables the torque necessary for
vehicle movement to be obtained).
●Tw o mechanical cables
– Convey the mechanical force to the rear brakes.
●Emergency control cable (in the central storage compartment on the LAGUNA, VEL SATIS and ESPACE and in
the boot on the SCENIC).
– Enables the rear brakes to be released in the event of the battery or parking brake failing.
●Warning lights and symbol on the instrument panel.
– Indicate application, releasing and any faults on the parking brake.
Note:
The parking brake cable play compensation is performed automatically by the control unit.
