    摘要: The invention relates to a method for reducing the risk of collision of a moving motor vehicle (301) with an object, comprising the following steps: determining (101) a first safety area (503) which determines a first delimited sub-area of a current environment of the moving motor vehicle (301); determining (103) of a second safety area (505) which determines a second delimited sub-area of a current environment of the moving motor vehicle (301); the second sub-area of the motor vehicle (301) is further away than the first sub-area; monitoring (105) the first and the second sub-areas on a moveable object in the respective safety area and/or on an object arranged within the respective safety area; controlling (107) a stopping process of a motor vehicle (301), when the monitoring shows that an object is located within the first safety area (503), in order to stop the motor vehicle (301); and controlling (109) one or more of the subsequent safety actions when the monitoring shows that an object is located within the second safety area (505); reducing the current speed of a motor vehicle; preparing a brake system of the motor vehicle (301) on a brake, testing the performed monitoring (105) of the second safety area (505). The invention also relates to a corresponding device (201), to a motor vehicle (301), to a car park (401), and to a computer program.

    摘要: A method for adaptive cruise control of a host vehicle (2): A host vehicle (2) includes at least one acceleration device (8), at least one retardation device (10), a control unit (14) for acting upon the acceleration device (8) and the retardation device (10), a calculating unit (16) for determining at least one parameter related to a lead vehicle (6) and a distance sensor (12) for determining a distance from the host vehicle to the lead vehicle (6). The method includes the steps of: setting a first predetermined time distance between the host vehicle (2) and the lead vehicle (6), maintaining the first predetermined time distance, evaluating a parameter that characterizes velocity changes of the lead vehicle in order to optimize a time distance between the host vehicle (2) and the lead vehicle (6), changing the first predetermined time distance to a second predetermined time distance if the parameter that characterizes velocity changes reaches a threshold value, and maintaining the second predetermined time distance. A system, a vehicle, a computer program product and a computer program for the method are further described herein.

    摘要: A device and a method for controlling vehicle speed in a vehicle equipped with cruise control when the vehicle is travelling downhill. The method involves driving a vehicle downhill with the cruise control set to a first brake set speed value; detecting a current vehicle speed; applying a brake torque using at least one auxiliary brake to maintain the first brake set speed, which brake torque is dependent on a currently engaged gear; detecting a manual request for a downshift from a currently engaged gear to a lower gear, in order to decrease vehicle speed; and determining if a downshift is permissible at the current vehicle speed. If a control unit determines that a downshift is not permissible, then the control unit is automatically arranged to apply a brake torque using at least a vehicle service brake to retard the vehicle speed; to retard the vehicle from a current, first vehicle speed to a lower, second vehicle speed at which a downshift to a lower gear is permissible; and to perform a downshift to a lower gear when the second vehicle speed is reached. The cruise control brake set speed is set to a second brake set speed that is lower than the first cruise control brake set speed value; and a brake torque using at least the auxiliary brake is applied if a detected current vehicle speed exceeds the second brake set speed.
