1. A cruise control system for a motor vehicle, comprising:
a sensor device for measuring an operating parameter of the motor vehicle and for measuring a distance to an object located in front of the motor vehicle; and
a controller for controlling one of a speed and an acceleration of the motor vehicle as a function of the measured operating parameter and the measured distance to the object, wherein:
the controller includes a stop-and-go function for automatically controlling driving off, rolling, and stopping as a function of a movement of the object, and
the controller continuously checks the sensor device during the stop-and-go operation for at least one predefined condition, wherein the at least one predefined condition includes a turning operation of the motor vehicle, and wherein the turning operation is detected when a turn radius is smaller than a predefined threshold value, the turn radius being determined by an evaluation of one of a yaw rate signal and a steering angle signal, and in the presence of the at least one predefined condition initiates a procedure for the shutdown of the stop-and-go function.
