Embodiment Construction

[0024] The drawing shows a schematic illustration of a preferred travel assistance device 10 . The drive support device 10 includes a central data processing unit 11 for controlling all the following processes. Also integral is a data acquisition unit 12, which is connected to a plurality of sensors, in particular wheel sensors 14, yaw rate sensors (Gierrate sensor) 15 and steering angle sensors 16, in order to calculate the road section to be traversed based on the sensor signals ( track) segment data. These route section data are then stored in the track storage unit 18 . The driving support device 10 also comprises a control unit 20 which controls the not shown vehicle on the basis of the trajectory stored in the trajectory-storage unit 18, in particular by controlling the vehicle steering 22, the vehicle gearshift 24 and the accelerator 26. Take control. Therefore, the vehicle can automatically travel along the road of any one of the trajectories stored in the trajector...

Abstract

Driving assistance apparatus 10 is provided for assistance with driving a vehicle along narrow roadways. The apparatus 10 comprises a data acquisition unit 12 for acquiring data on the route trajectory to be covered from wheel and steering angle sensors 14, 16, and a trajectory storage unit 18 for recording the route data. A unit 20 is provided for triggering the motor vehicle on the basis of the recorded route data and for driving along the recorded route in the same or reverse direction. This comprises a satellite navigation unit 28 for determining the absolute position of the motor vehicle as well as digital map data 38 with position attribute data for checking whether the motor vehicle is located in the vicinity of road areas with restricted scope for navigation. In such a case the recording of a trajectory is suggested to the driver. Alternatively, the recording can be done automatically whilst the driver concentrates on manoeuvring. The invention can be for providing parking assistance and provides an option of controlled autonomous driving.

Description

technical field [0001] The invention relates to a driving support device for supporting driving on a narrow lane, the driving support device has a data acquisition unit, a storage unit and a control unit, and the data acquisition unit is used to obtain the passed vehicle from the wheel sensor and the steering angle sensor. The storage unit is used to record the road section data, and the control unit is used to control the vehicle based on the recorded road section data to drive in the same or opposite direction on the recorded road section. Background technique [0002] Such a driving support device is known from EP1858744B1, in which a shorter section trajectory of about 5 meters, which is driven by the relevant vehicle and calculated by means of wheel sensors and steering angle sensors, is recorded and automatic or opposite directions are provided. Partially autonomous driving, so that it is possible to drive across road areas in narrow situations, for example when drivin...
