Examples provide a system and method for controlled deceleration for parking a vehicle. The system includes a parking brake control device, a sensor configured to measure a speed of the vehicle and output a measured vehicle speed, a parking brake, a primary hydraulic system including a primary controller and a primary hydraulic pressure generator, and a secondary hydraulic system including a secondary controller and a secondary hydraulic pressure generator. The secondary controller is configured to determine whether the vehicle is travelling at a non-zero speed while the parking brake control device is actuated. In response to that determination, the secondary controller determines whether hydraulic braking via the primary hydraulic system is available. When hydraulic braking via the primary hydraulic system is not available, the secondary controller controls the secondary hydraulic pressure generator to generate hydraulic braking pressure.

Controlled deceleration for parking of a vehicle

A hill-hold control system for a vehicle. The hill-hold control system includes a first wheel brake (A,B), a second wheel brake (C,D), a braking indicator (brake pedal), a drive away indicator (accelerator), and a controller (). The controller is configured to determine that the vehicle is at standstill, detect from the braking indicator that braking is no longer desired, adjust a braking pressure at the first wheel brake, adjust a braking pressure at the second wheel brake, detect from the drive away indicator an operator's desire to drive away, and when the operator's desire to drive away is detected, removing the braking pressure at the first wheel brake and the braking pressure at the second wheel brake.
