Abstract:
1. A hill start assistance method for a vehicle in a stationary position on a hill by a braking system delivering a braking pressure, the braking system being connected to a master cylinder, driven by a pressure transmitted by a user by a brake pedal, the method comprising: determining a first pressure in the braking system transmitted by the brake pedal to maintain the vehicle in the stationary position on the hill; after a pressure sensor detects that the brake pedal has been released, starting a timer to run for a timed period; calculating a minimum maintaining pressure for maintaining the vehicle in the stationary position on the hill after the brake pedal has been released; and actively regulating the braking pressure in the braking system by controlling the braking pressure to decrease progressively from the first pressure to the minimum maintaining pressure so that, at an end of the timed period, the braking pressure is equal to a target pressure at least equal to the minimum maintaining pressure maintaining the vehicle in the stationary position on the hill.
