A method is provided for warning the driver of a motor vehicle equipped with a distance-related cruise control system of a potentially hazardous situation. The motor vehicle is kept at a standstill during the distance-related cruise control using a braking torque applied by the distance-related cruise control system. Leaving of the motor vehicle, or an intention of the driver to leave the motor vehicle, is recognized. When the leaving or the intention to leave of the driver is recognized, the applied braking torque is changed and/or modulated in such a manner that the motor vehicle experiences a movement perceptible by the driver.

Method for warning the driver of a motor vehicle equipped with a cruise control system

A distance-related cruise control system and method for a motor vehicle performs a speed control to a predefined desired speed during free travel of the motor vehicle and performs a distance regulation to a predefined distance to the vehicle traveling ahead during following travel. After deactivation of the distance regulation during following travel, the system performs a speed control, not to the previously defined speed, but rather to the current speed of the motor vehicle at the instant of the deactivation of the distance regulation as the desired speed.

Distance related cruise control system and method

A method for the longitudinal control of a vehicle, in which information of a navigation system is detected and in which, as a function of the information of the navigation system, a desired value of at least one parameter for the longitudinal control is defined, during a longitudinal control operation, on the basis of a defined desired distance from a preceding vehicle by means of information of the navigation system. The probability is determined with which the preceding vehicle and/or the own vehicle is cornering when the preceding vehicle is no longer detected. A longitudinal acceleration takes place in a time-delayed manner when the probability is greater than a defined threshold.

Method for the longitudinal control of a vehicle in which information of a navigation system is detected

A distance-related cruise control system for motor vehicles has an electronic control unit, by which in the event of a distance-controlled following travel with a defined following distance from a vehicle driving ahead, when the speed of the vehicle falls below a defined first threshold, in the event of a further decrease of the speed of the vehicle driving ahead, the deceleration capability is reduced independently of the maintenance of the following distance. Preferably, the momentarily defined following distance is first increased when the speed falls below a defined second threshold which is larger than the first threshold.

Distance-related cruise control system

In a distance-related electronically controlled cruise control system for motor vehicles, in which, during a first regulating operation, a predetermined speed is essentially maintained until a preset minimum distance from a leading target vehicle is reached or undershot, and in which, during a second regulating operation, following the reaching or undershooting of this preset minimum distance, a speed regulation takes place in such fashion that the set minimum distance is maintained by following the target vehicle ahead at a regulated distance, and in the event of detection of a standing object ahead of the target vehicle traveling ahead of the source vehicle during the second regulating operation, after the previously leading target vehicle veers aside thus causing a transition from the second regulating operation back to the first regulating operation, acceleration to the preset speed is prevented if the distance to the standing object is below a first threshold and/or if the actual speed is below a second threshold.
