Problems solved by technology

[0003] In everyday traffic, the narrow position assistant can be used, for example, when passing a motorway construction site, where two roadways for one-way traffic are arranged parallel to each other, but due to their reduced width can only be used in an extremely concentrated driving mode. use
At this time, especially when trying to overtake another vehicle, it presents a special challenge

Embodiment Construction

[0011] The narrow position assistance system according to the invention has a vehicle geometry recognition module 1 , a vehicle mobility recognition module 2 and a surroundings recognition module 3 in the motor vehicle. The vehicle geometry recognition module 1 has a memory for storing the empirically determined vehicle geometry itself and / or sensors for measuring the vehicle geometry itself. At the same time, movable or steerable body parts such as exterior mirrors, diffusers, spoilers, etc. are taken into account. Variable vehicle geometries are thus known which can be the smallest possible vehicle geometry by corresponding adjustment of the movable body parts. The vehicle mobility recognition module 2 recognizes, in particular, information about the turning circle of the vehicle itself or information about different driving possibilities or maneuvering possibilities associated with driving forward or reversing. The surrounding environment recognition module 3 recognizes or...

Abstract

The path assistance system comprises a vehicle geometry knowledge module (1), a vehicle mobility knowledge module (2) and an environment-aware module (3). The vehicle geometry knowledge module and vehicle mobility knowledge module are connected with function module (4) so that a minimum possible driving path (5) is determined. The function module is provided to compare minimum possible driving path with maximum possible driving path (6) from the environment-aware module.

Description

technical field [0001] The invention relates to a narrow position assistance system in a motor vehicle. Background technique [0002] The applicant has developed a so-called narrow spot assistant, by means of which a (single) narrow spot is measured predictively and the driver is informed whether this narrow spot is wide enough for the vehicle to drive itself through. The narrow position assistance system developed by the applicant so far is based on the lane keeping assistant (Spurhalte-Assistanten) which is already available in series and is supposed to help the driver correctly assess narrow passages and drive while driving, for example in a highway construction site. Stay on course while passing. To measure narrow positions, the electronic system scans forward with a laser scanner and uses ultrasonic sensors that estimate the side distance to obstacles such as guardrails or other vehicles. [0003] In everyday traffic, the narrow position assistant can be used, for exa...
