Semi-Autonomous Forward Parking Control Using Sensor Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems for parking in perpendicular spaces require complex and expensive environmental sensors, and do not effectively support drivers during forward parking maneuvers.
Innovation Solution
A driver assistance device that uses sensor data to determine a parking lane and control the vehicle's steering and acceleration semi-autonomously or automatically, allowing the driver to focus on accelerating and braking while the system handles steering and positioning within a perpendicular parking space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex environmental sensors are used to detect parking spaces, then parking detection accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The sensor device is designed to serve multiple functions: it detects both the presence of parking spaces and lateral obstacles using the same sensor array. The control device processes sensor data to determine both parking lane positions and obstacles, eliminating the need for separate specialized sensors for each function.
Solution Approach 2:
The sensor detection area is divided into multiple regions: a first region for detecting parking spaces and a second region for detecting lateral obstacles. This segmentation allows the system to process different types of information from the same sensor device, improving detection accuracy without adding complex specialized sensors.
2Ease of operation
If full autonomous parking control is implemented, then driver workload is reduced, but system complexity increases
Solution Approach 1:
The system offers graduated levels of assistance rather than forcing full autonomous operation. The driver can choose to receive partial support (parking lane detection and suggestions) or full support (automatic steering control), allowing the system to match complexity to user needs and preferences.
Solution Approach 2:
The driver maintains ultimate control of the parking maneuver and can override or disengage the assistance system at any time. The system serves the driver's needs without taking complete control, preserving driver autonomy while providing support when desired.
3Adaptability or versatility
If forward parking is supported, then versatility of driver assistance is improved, but existing sensor configurations become insufficient
Solution Approach 1:
The sensor device and control system are designed to handle multiple parking scenarios (forward and reverse parking) using the same hardware configuration. The control device determines appropriate parking lanes and provides assistance based on the detected environmental conditions, adapting to different parking directions without requiring additional specialized sensors.

AI summary
The invention relates to a method for assisting a driver of a motor vehicle (1) when parking in a perpendicular parking space (14) by means of a driver assistance device, wherein environmental conditions of the motor vehicle (1) are detected by a sensor device (5, 6) of the driver assistance device and a parking path to be driven at least semi-autonomously by the motor vehicle (1) is determined depending on the environmental conditions by a control device (2) of the driver assistance device, wherein the motor vehicle (1) is parked forwards into the perpendicular parking space (14) and the determined parking path is driven through during forward parking.
