Embodiment Construction

[0040] figure 1 A flowchart illustrating a method for monitoring a desired trajectory of a vehicle.

[0041] The environment of the vehicle is detected according to step 101 . In step 103 the free space is ascertained based on the detected environment. In step 105 , based on the ascertained free space, the expected trajectory is checked with regard to collisions, in order to ascertain whether travel on the expected trajectory would lead to a collision.

[0042] Depending on the result of the check, it can be provided, for example, that the desired trajectory is discarded, a new desired trajectory being determined, which can then be checked similarly again with regard to the absence of collisions. The desired trajectory is ascertained or calculated in particular by means of a desired trajectory calculation device, which is preferably included by the device according to the invention. In particular, the desired trajectory is ascertained on the basis of the detected surroundin...

Abstract

A method for monitoring a setpoint trajectory of a vehicle, including the following: recording the surroundings of the vehicle, ascertaining a clearance based on the recorded surroundings and checking the setpoint trajectory for freedom from collision, based on the clearance, in order to ascertain whether traveling on the setpoint trajectory would result in a collision or not. Also described is a device for monitoring a setpoint trajectory of a vehicle and a related computer program.

Description

technical field [0001] The present invention relates to a method and a device for monitoring a desired trajectory of a vehicle. The invention also relates to a computer program. Background technique [0002] In highly automated driving, it is absolutely necessary for safety reasons to monitor the desired trajectory calculated by the vehicle before it is driven. In principle, the desired trajectory is usually checked with respect to collisions using all detected objects. If a desired trajectory leads to a collision, the desired trajectory will be classified as nonsensical and not driven. However, it is generally difficult to determine the actual size, especially the width and length, of an object. In particular environmental sensors such as radar sensors or monocular cameras are usually able to recognize an object anywhere within the visible range in the best case. Often, sensors are not able to determine the exact outline of an object. A detected object-based inspection...
