Problems solved by technology

[0010] A drawback of the systems described above is that the vehicle positioning accuracy is not sufficient to precisely and reliably control the vehicle in a piloted manner in harmony with the situational environment, i.e. not sufficient for the vehicle to drive autonomously

Embodiment Construction

[0026] Next, this method will be described by taking one sensor among many position detecting sensors installed in a parking building as an example. The position detection sensor is able to localize the vehicle with high precision, thereby enabling piloted, ie automatic, parking of the vehicle. A prerequisite for the piloting of the vehicle, that is to say the automatic parking, is that the position of the vehicle can be determined with high precision.

[0027] A first prerequisite for carrying out the method is that the parking garage used as an example has either already been mapped, ie for example a CAD architectural drawing exists, or the parking garage has been measured with high precision, ie the mapping environment has been generated from a mappable environment. This parking building must also be equipped with position detection sensors fixedly arranged therein. For this purpose, a plurality of position detection sensors are arranged in the parking garage in such a way...

Abstract

The invention relates to a method for determining a vehicle position of a vehicle to be located within a defined cruising range in a mapped environment, wherein the vehicle position is determined by evaluating the position data of at least one predetermined component of the vehicle, and the position data are made available particularly by way of a plurality of position detecting sensors, which are fixedly arranged within the mapped environment. The invention further relates to a corresponding device for determining a position of a vehicle. This allows piloted driving in a parking garage, for example.

Description

technical field [0001] The invention relates to a method and a device for determining the vehicle position of a vehicle to be positioned within a given driving range in a surveying and mapping environment. Background technique [0002] Modern vehicles feature driver assistance systems that actively intervene in driving situations. These systems are, for example, track warning systems, which not only warn the driver, for example, when driving past white road markings, but also prevent further passing of the markings by means of steering interventions. There are also additional driver assistance systems for driver comfort, such as parking systems, which can park the vehicle into a parking space without driver intervention. Most of these parking systems together with automatic speed control allow the vehicle to be parked automatically by means of steering intervention. [0003] But in order for the vehicle to be able to take over the driving task entirely or as the situation ...
