Autonomous Parking Hazard Detection and Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-driving car parking modules do not account for road hazards such as potholes, ice, mud, snow, or puddles, posing a risk to passengers disembarking from the vehicle.
Innovation Solution
A self-driving car equipped with sensors and a processor that identifies road hazards near the door using various sensor packages, such as polarization and spectroscopic sensors, and adjusts the parking position or warns the occupant to avoid these hazards, potentially deploying a bridge or ramp to span the hazard.

Engineering Contradiction Analysis
1Productivity
If the car parks in the detected available space, then parking efficiency is improved, but the passenger may disembark directly into a road hazard
Solution Approach 1:
The system performs preliminary detection of road hazards before finalizing the parking position. The processor identifies surface hazards in advance and adjusts the parking location to avoid them, ensuring the passenger disembarks from a safe location. This preliminary action prevents the harmful effect of passenger exposure to hazards while maintaining parking efficiency
Solution Approach 2:
The system uses sensor feedback to continuously monitor the parking environment and adjust the parking decision. If road hazards are detected near the intended parking spot, the system feedbacks this information to the parking controller, which then selects an alternative safe parking location, balancing efficiency with passenger safety

AI summary
A self-driving car includes a vehicle body; wheels mounted on the vehicle body for moving the car; brakes mounted on the vehicle body for stopping the wheels; a steering apparatus connected between the vehicle body and at least some of the wheels for steering the wheels; sensors configured to detect environmental parameters; and a processor that is configured to facilitate at least an autonomous parking module for controlling the wheels, brakes, and steering apparatus. The processor is further configured as part of the autonomous parking module to scan the surroundings of the self-driving car, using at least one of the sensors, in order to detect a road hazard proximate a door of the self-driving car.
