1. A method of automatically triggering a deceleration of a vehicle for one of preventing a collision and reducing consequences of an imminent collision, the method comprising:

  • providing at least one variable representing collision risk between the vehicle and another object, the another object being within a predetermined triggering range;

    varying the predetermined triggering range as a function of a driver response by signals from at least one of a steering angle sensor, a brake pedal sensor, and an accelerator pedal sensor; and

    lowering a first threshold value for automatically triggering the deceleration when a driver operates a brake pedal if both (a) the driver'"'"'s operation of the brake pedal is less than a braking pressure of the automatically triggered deceleration, and (b) there is a manual change in a steering angle in which a steering wheel angular velocity does not exceed an absolute value of a predetermined steering wheel angular velocity.
