Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous and semi-autonomous driving assistance systems face challenges in ensuring process responsibility, particularly in preventing hazards to people and vehicles during maneuvers like parking, as they lack effective methods to communicate the vehicle's intended direction of movement to other road users.
Innovation Solution
Incorporating a light signal device within the assistance system, such as a TopView system, to display the vehicle's direction of movement using light sources or projection means, allowing other road users to be informed about the vehicle's trajectory, enabling flexible reaction to environmental situations and reducing accident risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous or semi-autonomous driving maneuvers are carried out without additional communication means, then the system complexity is reduced, but the safety and hazard prevention capability deteriorates due to lack of communication with other road users
Solution Approach 1:
A light signal device is introduced as an intermediary communication means between the vehicle's assistance system and other road users. The device displays directional information about the vehicle's intended movement using light patterns, enabling other road users to anticipate and react to autonomous maneuvers without requiring complex inter-vehicle communication protocols
Solution Approach 2:
The patent replaces potential mechanical or electronic communication systems with an optical communication approach. By using light signal devices to display movement direction, the system achieves effective communication with other road users through a simpler, more intuitive optical interface rather than complex mechanical linkages or electronic protocols
2Object-affected harmful factors
If the vehicle's direction of movement is displayed using light signal devices, then the hazard warning capability is improved, but the energy consumption increases
Solution Approach 1:
The light signal device operates periodically or intermittently based on the vehicle's operational state, displaying directional information during autonomous or semi-autonomous maneuvers rather than continuously. This approach provides necessary hazard warning only when needed, reducing overall energy consumption while maintaining safety during critical operations
Solution Approach 2:
The system uses different light colors or patterns to convey directional information and operational states. By utilizing variations in light color and pattern rather than increasing light intensity or duration, the system achieves effective communication with minimal energy expenditure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively communicates the vehicle's direction, reducing the risk of accidents and hazards by allowing other road users to anticipate the vehicle's movement, thereby enhancing safety during autonomous or semi-autonomous driving maneuvers.
Implementation Method 1
at least one direction, in which the vehicle is moving during the autonomous or semi-autonomous driving maneuver, is displayed by means of at least one light signal device
Data Source
AI summary
The invention relates to a method and device for an assist system which serves for carrying out an autonomous or semi-autonomous driving maneuver of a vehicle, for example a parking assist system in a vehicle, image data being generated from vehicle surroundings by means of a camera system and being processed for carrying out the driving maneuver.
