Abstract

The invention relates to a method for automatically guiding a motor vehicle (1), the method comprising the steps of receiving a reference trajectory (31) for a route (30) to be traveled by the motor vehicle (1), by means of which a steering action is determined and / or a continuous sequence of acceleration actions and / or braking actions; detection of environmental data (11) from the detection device (10) of the motor vehicle (1); checking of the drivable reference trajectory (31) on the basis of the environmental data (11) properties, the driving trajectory (33) is generated by correcting the reference trajectory (31) according to the environmental data (11), and the motor vehicle (1) is automatically guided along the driving trajectory (33) by the controller (16) of the motor vehicle (1). ). In order to achieve a particularly proactive planning of the driving trajectory ( 33 ), the trajectory formed from the lane data ( 38 ) independently of the environmental data ( 11 ) is used as a reference trajectory ( 31 ), which describes the path along which the route ( 30 ) follows. Lane direction of the road (35).

Description

technical field [0001] The invention relates to a method for automatically guiding / controlling a motor vehicle, wherein the motor vehicle is automatically controlled along a route to be driven according to the trajectory. Background technique [0002] It is known from the prior art that the motor vehicle can be moved automatically. For this purpose, the environment of the motor vehicle is detected, for example, by at least one detection device, eg a lidar sensor, a camera, in particular a monocular or stereo camera, an ultrasonic sensor or a radar sensor. Road markings and other traffic participants such as other motor vehicles, cyclists or pedestrians, as well as obstacles can be detected. From the environmental data thus detected, a trajectory for the automatic movement of the motor vehicle can be calculated. Due to the limited range of action or effective detection distance of the detection device, forward-looking trajectory planning can only be implemented to a limited...
