Description

DETAILED DESCRIPTION

[0012] An autonomous driving system is configured to take the responsibility for driving the vehicle away from the driver as completely as possible. For this purpose, the autonomous driving system observes its surroundings using sensors and ascertains therefrom a model of the environment using surroundings-related and vehicle-related data, and autonomously determines necessary maneuvers of the vehicle. In certain critical situations, the driver is warned so that the driver retakes complete control over the vehicle. That is to say, either the motor vehicle is driving or the driver is driving. Both or a combination is to date not possible and is to be made possible by the present invention.

[0013] The driving system according to the present invention has the advantage that in autonomous driving operation the driver remains at least under the impression of maintaining complete control over the vehicle such that for the driver no loss of control is noticeable. Thus, a positive sensation is also possible for vehicle drivers, in particular handicapped vehicle drivers, who due to their age or their lack of motivation are no longer able to drives so well or who as beginning drivers do not yet have the necessary experience. These vehicle drivers are quasi left to believe in good faith that they always have the vehicle completely under control, while in the background the driving system always initiates all necessary steps to keep the vehicle safely in its lane for example.

[0014] According to the present invention, a driver command is initiated by an interaction of the driver and is accommodated immediately by the autonomous driving system if this is possible following an evaluation of the data. The data or the possibility of accommodating the driver command and initiating a specific driving maneuver is determined by information of the sensors and its evaluation in the computer unit. The driver indicates for example by a steering-wheel motion that he would now like to pass another vehicle, and the driving system checks autonomously with the aid of sensors, such as front radar sensors, front video camera as well as rear radar sensors, whether it is able to pass. This is followed by an automatic steering operation and an autonomously performed passing maneuver that are controlled by the driving system via the computer unit. For this purpose, smaller steering angles may be filtered out via filters provided in the computer unit and the lane may be maintained automatically.

[0015] Thus it is possible to read in the steering wheel angle in the computer unit and to filter it via at least one filter. The intention to drive straight ahead, to turn off or to perform a passing maneuver is detected with the aid of multiple corresponding filters. With the aid of the sensors installed in the vehicle, it is possible to detect or check via the computer unit whether based on the data a passing maneuver is possible, and this passing maneuver may then also be initiated.

[0016] The autonomous driving system according to the present invention represents an advantageous supplement to known autonomous driving systems.
