A method for controlling brake pressure during a shift of a vehicle out of park may include determining that a first status condition is met when the vehicle is in park with an electric parking brake applied, determining that a second status condition is met when the vehicle is not moving, responsive to detecting a shift of the vehicle out of park when the first and second status conditions are both met, directing a build-up of brake pressure until a brake pressure target is reached, and holding the brake pressure at the brake pressure target until a release condition is met.

Brake system with shift out of park support

Performance electric parking brake controllers determine braking control signals for a performance electric parking brake system of a vehicle based on differing sets of operating conditions of the vehicle. A controller is configured to electromechanically actuate rear brake calipers of the vehicle in response to a first set of operating conditions of the vehicle, to hydraulically actuate front brake calipers and the rear brake calipers of the vehicle in response to a second set of operating conditions of the vehicle, and to hydraulically actuate only the rear brake calipers in response to a third set of operating conditions of the vehicle.

Performance electric parking brake controllers

Performance electric parking brake controllers determine braking control signals for a performance electric parking brake system based on a position of a parking brake lever. A parking brake lever has a first rate of resistance associated with movement in a first direction away from a neutral position and a second rate of resistance associated with movement in a second direction away from the neutral position opposite the first direction. The first and second rates of resistance are different. A controller is configured to electromechanically actuate rear brake calipers of the vehicle in response to a first set of operating conditions of the vehicle, to hydraulically actuate front brake calipers and the rear brake calipers of the vehicle in response to a second set of operating conditions of the vehicle, and to hydraulically actuate only the rear brake calipers in response to a third set of operating conditions of the vehicle.

The present disclosure relates to various computer-implemented methods of line-locking a hydraulic vehicle braking system. A method includes performing a preliminary system check and controlling the distribution of fluid between a hydraulic module and an individual wheel-end brake component when the preliminary check is satisfied. The system continues to monitor predetermined vehicle inputs during activation.
