A method for controlling a pressure (32, 34) in an injection system (14) for an engine (12) of a vehicle (10) comprises the following steps: determining whether the vehicle (10) is decelerating; reducing the delivery rate of a high-pressure pump (16) that supplies fuel to the injection system (14); reducing the pressure in the injection system (14) to a standstill pressure (ps) by means of idle operation of the engine (12); estimating a standstill time (t1) at which the vehicle (10) comes to a standstill; and reducing the delivery rate of the high-pressure pump (16) before the standstill time (t1) is reached, such that the standstill pressure (ps) is attained in the injection system (14) at the standstill time (t1).
