Autonomous Vehicle Display for Driving Plan Confidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic vehicle control systems often switch from automatic to manual mode without sufficient warning to the driver, requiring the driver to determine when errors occur and necessitate a switch, which can be problematic due to lack of information about system operation.
Innovation Solution
A control system that includes exterior sensors to sense the environment, a processor to calculate a driving plan and confidence level, and a display to show the driving plan and confidence level, allowing the driver to be informed about the vehicle's operation and potential need to take over manual control.

Engineering Contradiction Analysis
1Extent of automation
If the control system operates in automatic mode with minimal driver intervention, then the extent of automation is improved, but the driver awareness of system operation deteriorates
Solution Approach 1:
The system implements feedback by displaying the calculated driving plan and confidence level to the driver. The display shows visual representations of the planned trajectory and the system's confidence in executing that plan, allowing the driver to monitor system operation and understand when manual intervention may be needed.
Solution Approach 2:
The display acts as an intermediary between the automatic control system and the driver. It translates complex sensor data and processing decisions into comprehensible visual information about the driving plan and confidence level, bridging the information gap without requiring the driver to directly interact with the control algorithms.
2Loss of information
If the system provides detailed information about operation and confidence level, then the driver awareness is improved, but the device complexity increases
Solution Approach 1:
The system extracts only the most critical information for driver awareness - the driving plan trajectory and confidence level - and displays them separately. This avoids overwhelming the driver with all sensor data and processing details while still providing sufficient information for safe operation.
Solution Approach 2:
Different parts of the display provide different types of information tailored to specific driver needs. The driving plan visualization shows spatial trajectory information, while the confidence level indicator provides a separate quantitative measure of system certainty, allowing the driver to quickly assess different aspects of system operation.

AI summary
Methods and control systems are provided for automatically controlling operation of a vehicle. In one embodiment, the control system includes an exterior sensor for sensing the environment outside the vehicle. A processor is in communication with the exterior sensor and configured to calculate a driving plan of the vehicle based at least partially on the sensed environment outside the vehicle. The processor is also configured to calculate a confidence level of the driving plan of the vehicle based at least partially on the sensed environment around the vehicle. The control system also includes a display in communication with the processor and configured to receive data from the processor and display a representation of at least one of the driving plan and the confidence level.
