Abstract
A hill-hold control system for a vehicle. The hill-hold control system includes a first wheel brake (120A, 120B), a second wheel brake (120C, 120D), a braking indicator (brake pedal), a drive away indicator (accelerator), and a controller (130). 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.
