Driver Assistance Object Distance Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems cannot selectively display the shortest distance to a specific object and provide targeted information to the driver, leading to confusion about the reason for warnings, especially in complex maneuvers like parking.
Innovation Solution
The method allows drivers to select detected objects, display their distances, and provide visual, acoustic, or haptic feedback, enabling informed decision-making during maneuvers by highlighting relevant objects along the predicted driving path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays the shortest distance to the nearest object only, then the system complexity is low, but the driver cannot obtain targeted information about specific objects of interest
Solution Approach 1:
The system segments the display information by allowing the driver to select specific objects of interest from multiple detected objects. Instead of displaying only the nearest object, the system divides the information presentation into selectable object units, enabling targeted distance information for multiple specific objects simultaneously.
Solution Approach 2:
The system implements dynamic object selection capability where the driver can actively choose which objects to monitor. The display dynamically updates to show distance information for selected objects rather than a fixed single nearest object, making the information system adaptable to driver needs.
2Loss of information
If the system provides comprehensive distance information to all detected objects, then the driver receives complete information, but the driver becomes confused about the reason for warnings
Solution Approach 1:
The system applies local quality by providing detailed distance information specifically for selected objects of interest rather than uniformly to all objects. The driver can focus information presentation on locally relevant objects (e.g., specific parking space boundaries, particular obstacles) to improve understanding without overwhelming with all data.
Solution Approach 2:
The system introduces an intermediary selection mechanism between the driver and the comprehensive object data. The driver selects objects through an interface that acts as an intermediary, filtering and presenting only the distance information for chosen objects, thereby maintaining completeness while improving clarity.
3Ease of operation
If the system only displays distance to the nearest object, then the device complexity is low, but drivers with mobility restrictions must turn their heads to gather sufficient information
Solution Approach 1:
The system transitions from a single-dimension nearest-object display to a multi-dimensional information presentation where distance data for multiple selected objects is displayed simultaneously. This dimensional expansion allows drivers to obtain comprehensive spatial information without head turning, as all relevant distances are presented in one view.
Solution Approach 2:
The system enables drivers to self-select objects of interest through an intuitive interface, allowing them to customize their information display according to their specific maneuvering needs. This self-service capability empowers drivers to configure the information presentation without additional assistance or complex system adjustments.
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
This approach enhances driver understanding and safety by allowing targeted selection and display of object distances, reducing the need for additional information sources and minimizing head-turning, especially for drivers with mobility restrictions, and preventing collisions by alerting the driver at predetermined minimum distances.
Implementation Method 1
suitable ultrasonic transmitters are used to send signals that are reflected by an obstacle. The reflected ultrasonic waves are received and the distance to an obstacle is determined based on the time that elapses between the signal being transmitted and the echo being received.
Implementation Method 2
the distance to an obstacle is determined based on the time that elapses between the signal being transmitted and the echo being received
