Abstract:
A method for controlling an internal combustion engine of a motor vehicle having a brake assembly including a brake force amplifier, the engine having an intake manifold wherein pressure varies during operation of the engine and the brake assembly being equipped with an auxiliary brake force system wherein the auxiliary force is generated by coupling said brake force amplifier to the intake manifold pressure of said engine, the method comprising the steps of:after a cold start, operating said engine in the warm-up phase at increased intake manifold pressure and providing an increased throughout of the air/fuel mixture by driving one of the following to open to a first position: a throttle flap or an idle adjusting element; and,effecting a reduction of the intake manifold pressure when the brake assembly is actuated by effecting a drive of said throttle flap or said idle adjusting element to a second position wherein said throttle flap or said idle adjusting element remains open but less open than in said first position.
