Parking Assistance Rear Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking systems face challenges in avoiding rear-end collisions during the search for a parking space, as they often require drivers to brake suddenly, which can lead to close following vehicles not being able to stop in time due to the limited speed and sudden braking maneuvers.
Innovation Solution
A method for operating a driver assistance system that monitors the rear area during the search for a parking space and warns the driver of potential rear-end collisions by adjusting the braking maneuver based on the presence of following vehicles, allowing for cautious braking when necessary and informing following vehicles of impending braking actions through vehicle-to-vehicle communication.

Engineering Contradiction Analysis
1Measurement precision
If the vehicle drives below a certain activation speed to measure parking spaces accurately, then measurement precision is improved, but the risk of rear-end collisions increases due to sudden braking maneuvers
Solution Approach 1:
The system performs preliminary monitoring of the rear area before executing braking maneuvers. By detecting following vehicles in advance and issuing warnings to both the driver and the following vehicle, the system prepares all parties for potential braking actions, thereby preventing rear-end collisions while maintaining accurate parking space measurement at low speeds
Solution Approach 2:
The system implements a feedback mechanism where the monitoring of the rear area provides continuous information about following vehicles. This feedback loop allows the system to adjust braking behavior based on real-time conditions, warning the driver and communicating with following vehicles to coordinate safe braking maneuvers that maintain measurement precision without causing collisions

AI summary
A method for operating a driver assistance system when parking a vehicle (01) in a lateral parking space (02) along a roadway is described, wherein, below a certain activation speed and during the search for a parking space, possible parking spaces (02) are measured, and in the case of a parking space (02) that is sufficiently long for the vehicle (01) information is issued to the driver pointing out a suitable parking space (02) found, wherein the rear area (03) of the vehicle (01) is monitored during the search for a parking space when the activation speed is no longer met and the driver of the vehicle (01) is warned by a sudden braking maneuver about a following vehicle (05) present in the rear area (03) before a possible rear-end collision. In addition, a driver assistance device for carrying out the method is provided, and a computer program product is described, which prompts a microprocessor having pertinent storage media to carry out the method.
