ELECTRONIC PARKING BRAKE SYSTEM

摘要

An electronic parking brake system having selectable modes and varying parking brake actuation dependent on the selected mode and amount of parking brake application being requested. The system provides for varying interfaces with varying programmed outputs to control a vehicle's parking brake. One such mode being a boat launch mode in which an electronic parking brake is initially actuated to 100%, the amount of parking brake application is displayed, and the driver is allowed to modulate the parking brake application through + and − buttons in combination with the visual display to allow the vehicle to back down a boat ramp using gravity.
