Camera-Based Parking Restriction Detection in Motor Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems for vehicles do not effectively provide drivers with information about no-parking and no-stopping zones, which can lead to accidental violations, especially in complex urban environments where traditional traffic signs are being replaced by solid yellow lines.
Innovation Solution
A driver assistance system equipped with a camera that detects roadway markings, including no-parking and no-stopping spots, and outputs warning messages optically and acoustically to the driver when such zones are detected, utilizing a control device that analyzes image data from the camera and integrates with the vehicle's systems to determine its parked or stopped state, and includes a navigation device for location-specific detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional traffic signs are replaced by solid yellow lines to reduce the jungle of traffic signs, then the complexity of traffic signage is reduced, but the detectability and awareness of parking restrictions by drivers deteriorates
Solution Approach 1:
The patent introduces a camera-based detection system and control unit as intermediaries between the solid yellow line markings and the driver. The camera captures images of the roadway markings, the control unit analyzes them to detect no-parking zones, and triggers visual or acoustic warnings to alert the driver, thus mediating the information transfer from the simplified markings to the driver
Solution Approach 2:
The patent replaces the mechanical/visual system of traditional traffic signs with an electronic detection and warning system. Instead of relying on drivers to visually perceive and interpret solid yellow lines, the system uses a camera to capture images, processes them electronically to detect markings, and substitutes the direct visual information with electronic warnings through displays or acoustic signals
2Measurement precision
If a camera-based detection system is added to detect roadway markings, then the detection capability of parking restrictions is improved, but the device complexity increases
Solution Approach 1:
The patent makes the camera and control unit serve multiple functions: they detect not only no-parking zones but also lane markings and provide lane departure warnings. This multi-functionality justifies the added complexity by providing additional driver assistance benefits beyond just parking restriction detection
Solution Approach 2:
The system uses the vehicle's existing camera and processing resources to perform the detection function, rather than requiring entirely separate dedicated hardware. The control unit integrates the parking restriction detection with the existing lane detection functionality, allowing the system to serve itself by utilizing already-present components

AI summary
The invention relates to a driver assistance system for a motor vehicle including a camera for detecting roadway marking. According to the invention a device is provided for detecting a parked or stopped mode of the vehicle. Furthermore, a control device receives image data of the surroundings of the vehicle from the camera in the parked or stopped mode and analyzes the image data with respect to roadway markings which indicate no-parking and/or no-stopping spots, wherein the control device controls a signaling device such that the signaling device outputs a warning message in the event that a roadway marking indicating a no-parking spot or a no-stopping spot is detected in the surroundings of the stopped or parked vehicle.
