Problems solved by technology

However, the parking distance covered by the object from entering the detection range of the ultrasonic sensor system to the actual stop of the vehicle after braking depends decisively on the waiting time for object detection; however, this waiting time can increase significantly in the presence of interfering echoes

Embodiment Construction

[0044] figure 1 An exemplary embodiment of the method according to the invention for adapting the driving speed is shown. According to step 110, for each object recognition process i, the number m of the respective detection trials carried out within the scope of the corresponding object recognition process i stored in the data area. In this case, however, only the number m of measurement trials greater than the predetermined number n of object detections for evaluating an object as a recognized object is stored i . For example, the predetermined times n is equal to 3, in this case only the times m greater than n=3 are stored i . In addition to the corresponding times m i In addition, the value of the vehicle travel distance is also stored, which roughly represents the position of the travel travel at which the corresponding number of measurement trials performed is m i The object recognition process i.

[0045] The number of measurement trials m i A measurement test w...

Abstract

A first aspect of the inveiton relates to a method for adapting the travelling speed, adjusted through a driver assistance system, of a motor vehicle. The vehicle motor is provided with an supersonic wave sensing system used for object identification of objects outside a vehicle, the driver assistance system preferably relates toa parking assistance system having automatic horizontal and lengthwise guiding functions, and object identification of objects in a supersonic wave sensing system detection scope is performed in a potential-supersonic-wave-interference-source-relevant manner in such a way that waiting time is delayed. According to the method, increase of objection identification waiting time is ascertained, and driving speed is enabled to adapt to the waiting time.

Description

technical field [0001] The invention relates to a method for adapting a driving speed of a motor vehicle regulated by a driver assistance system and a corresponding driver assistance system. Background technique [0002] The driver assistance system is preferably a parking assistance system with automatic lateral and longitudinal guidance. [0003] In the case of a parking assistant with automatic lateral guidance, the system takes over the steering of the vehicle during the parking process. The driver himself has to undertake the longitudinal guidance by correspondingly oiling and braking. In the case of a parking assistant with automatic lateral and longitudinal guidance, the task of longitudinal guidance is also taken over by the parking assistant. In such a parking assistant system with automatic transverse and longitudinal guidance, the driver can usually park the vehicle automatically and optionally park it out by actuating an operating element. [0004] For longitu...
