Description And Operation: Overview
WARNING: This page is about a different car, the 2015 Land Rover LR2, 2014 Land Rover LR2, and 2013 Land Rover LR2. However, it is still accessible from the selected car via links, so may be relevant.
The Electronic Parking Brake (EPB) is an electrically actuated system that operates the calipers on the rear brakes. The system consists of:
- an EPB switch
- two EPB actuators
- an EPB module
- indicator lamps, text messages and warning tones.
The EPB is controlled by the EPB module, which uses the EPB actuators to apply and release the rear disc brakes. Operation of the EPB is initiated by the EPB switch and software within the EPB module. The EPB has the following operating modes:
- static apply/release
- gradient dependant apply
- ignition off apply
- DAR (Drive Away Release)
- automatic transmission apply/release
- high temperature re-clamp
- driver exit warning
- dynamic apply.
Signals from other vehicle systems for operation of the EPB are transmitted to the EPB module on the high speed Controller Area Network (CAN) bus.
