Trailer-Aware Driver Display With Rear Perspective Lane View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in quickly and easily perceiving how to adjust their vehicle control when towing a trailer, as existing systems often fail to provide clear and intuitive information about the trailer's presence and its impact on vehicle behavior, leading to potential safety hazards.
Innovation Solution
A driver information system that generates a perspective view of the ego-vehicle from behind, including a trailer object represented in the driver information display, which records the trailer's operating state using sensors and image recognition, providing a simplified and intuitive representation of the driving situation, including lane markings, road conditions, and environmental data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a comprehensive selection of driver assistance systems is provided, then vehicle control automation and safety are improved, but the complexity of the interface between driver and controlling systems increases
Solution Approach 1:
The patent creates a virtual copy of the physical driving situation by generating a perspective view that replicates the driver's outward view from behind the ego-vehicle. This virtual representation simplifies the presentation of complex trailer-related information by showing lane markings, road boundaries, and environmental features in an intuitive format that mirrors reality, reducing the cognitive load on the driver while maintaining comprehensive safety information
2Loss of information
If detailed information about trailer operating state is provided, then driver awareness is improved, but the time required to process and understand the information increases
Solution Approach 1:
The patent applies local quality by selectively presenting information based on its spatial and contextual relevance. The perspective view displays trailer-related information only in the specific regions where it is relevant to the driving situation, such as showing lane markings and road boundaries in the areas affected by the trailer's presence. This localized presentation allows the driver to quickly grasp critical information without being overwhelmed by comprehensive but irrelevant data
Solution Approach 2:
Instead of presenting trailer operating state data in traditional dashboard formats that require interpretation, the patent inverts the approach by rendering a perspective view that mirrors the driver's natural outward view. This inversion transforms abstract data into an intuitive visual representation that aligns with the driver's existing mental model of the driving environment, enabling immediate comprehension without additional processing time
3Ease of operation
If a perspective view from behind the ego-vehicle is generated, then the representation of vehicle behavior with trailer is simplified, but the computational requirements and system complexity increase
Solution Approach 1:
The perspective view generation system serves multiple functions simultaneously: it displays lane markings for navigation guidance, shows road boundaries for spatial awareness, renders environmental features for contextual understanding, and indicates trailer position and impact zones. By consolidating these multiple information streams into a single unified perspective view, the system achieves multi-functionality that simplifies driver interaction while the underlying system handles the computational complexity of integrating data from multiple sensors and processing engines
Data Source
AI summary
A method for operating a driver information system in an ego-vehicle is provided, wherein an operating state of a trailer device of the ego-vehicle is recorded. A driver information display is generated and output, wherein the driver information display comprises an ego-object which represents the ego-vehicle. In addition, the ego-object is represented from behind in a perspective view and the driver information display also comprises a lane object which represents a road section lying in front of the ego-vehicle in the direction of travel. The driver information display also comprises a trailer object which is formed according to a recorded operating state of the trailer device and which represents an attached device.
