Autonomous Vehicle Alarm Response via Wireless Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In parking environments, fully automatic vehicle guidance systems face challenges in responding to alarm states when there is no driver present, as they cannot perceive optical or acoustic warnings, leading to potential hazards.
Innovation Solution
A method where alarm information is transmitted via a wireless communication link from a control device to autonomously operated motor vehicles, allowing them to evaluate the situation and take measures to reduce hazards, such as switching off engines or clearing escape routes, based on predefined criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If fully automatic vehicle guidance is implemented without a driver present, then automation level is improved, but the ability to perceive and react to alarm states deteriorates
Solution Approach 1:
The patent introduces an intermediary communication system that transmits alarm information from the parking environment's optical/acoustic alarm devices to the autonomous vehicle's control unit. This mediator enables the vehicle to receive and process alarm signals without a driver present, resolving the contradiction between high automation and reliable alarm response.
Solution Approach 2:
The autonomous vehicle is equipped with the capability to independently receive, evaluate, and respond to alarm information through its control unit. The vehicle autonomously determines appropriate measures based on the alarm type and its current state, eliminating the need for driver intervention while maintaining reliable alarm response.
2Reliability
If alarm information is transmitted to all vehicles, then safety is improved, but communication data volume increases
Solution Approach 1:
The patent applies local quality by transmitting alarm information selectively based on the vehicle's location and relevance to the alarm. The control unit evaluates whether the alarm applies to the specific vehicle's situation, ensuring that only necessary vehicles receive and process the alarm data, thus reducing overall communication data volume while maintaining safety.

AI summary
Method for operating a parking environment with at least one motor vehicle which has a vehicle system which is designed for completely automatic vehicle guidance and is operated autonomously for parking purposes in the parking environment, wherein the parking environment is assigned a motor-vehicle-external control device which is designed to set up a wireless communication link to motor vehicles which are operated autonomously in the parking environment and to coordinate the autonomous operation of the motor vehicles in the parking environment, wherein, when an alarm signal which indicates an alarm state in the parking environment is present, in particular acoustically and/or optically output via display means of the parking environment, alarm information which describes the type of alarm is transmitted, via the or a further wireless communication link, to all the autonomously operated motor vehicles which are located in the parking environment, wherein the vehicle systems of the motor vehicles receiving the alarm information evaluate said information by means of at least one measure criterion, wherein, when the measure criterion is satisfied, at least one alarm-related measure which eliminates or reduces a hazard owing to the alarm is carried out automatically.
