Abstract
An anti-rollback control system for a vehicle having a brake system includes a brake pedal that is operable to induce a brake pressure in the brake system and a control module that holds the brake pressure equal to a hold pressure that is based on an incline angle to inhibit rollback of the vehicle when pressure is relieved from the brake pedal. The control module initiates forward propulsion of the vehicle based on a driver input and reduces the brake pressure from the hold pressure concurrent to initiating the forward propulsion.
