Vehicle Speed Profile Display for Driver Confidence Ahead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers may feel disoriented and lack confidence in assistive driving features when the vehicle's behavior deviates from their expectations due to environmental changes, especially in off-road driving, and the lack of clear and timely representation of the vehicle's behavior ahead, and the lack of clear and timely representation of the vehicle's behavior ahead.
Innovation Solution
A control system that uses sensors to determine a speed profile and route data, generating a visual, audio, or haptic representation of the vehicle's behavior on the route ahead, providing markers indicating speed changes and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If assistive driving features automatically control vehicle speed based on environmental conditions, then vehicle safety and energy efficiency are improved, but driver confidence and sense of control deteriorate due to unexpected vehicle behavior
Solution Approach 1:
The system provides continuous feedback to the driver through a visual representation displaying the speed profile and environmental conditions. This feedback loop allows the driver to understand the rationale behind automatic speed adjustments, maintaining confidence while benefiting from safety improvements. The representation shows upcoming speed changes and their causes, enabling the driver to anticipate and comprehend vehicle behavior.
Solution Approach 2:
The visual representation acts as an intermediary between the automatic control system and the driver. It translates complex sensor data and control decisions into an intuitive display that bridges the gap between automated operation and driver understanding, allowing the driver to mentally engage with the system's decision-making process without manual intervention.
2Loss of information
If the vehicle provides detailed real-time information about speed profile and environmental conditions, then driver confidence and situational awareness are improved, but device complexity and information processing requirements increase
Solution Approach 1:
The system extracts only the most relevant information from complex sensor data and control parameters, displaying selectively chosen elements such as upcoming speed changes, distance to changes, and key environmental factors. This extraction approach provides comprehensive situational awareness without overwhelming the driver or requiring excessive processing of all possible data points.
Solution Approach 2:
The information display is segmented into distinct, manageable components including speed profile indicators, distance measurements, and environmental condition icons. This segmentation organizes complex data into discrete visual elements that are easier to process and understand, reducing the cognitive load on the driver while maintaining complete situational awareness.

AI summary
Embodiments of the present invention provide a control system for a vehicle. The control system is configured to receive speed profile data indicative of a speed profile of the vehicle, wherein the speed profile represents one or more speeds at which the vehicle will be automatically controlled to travel at on a route ahead of the vehicle; receive route data indicative of the route ahead of the vehicle; determine, using the received speed profile data and the received route data, a representation comprising a relative position of the vehicle with respect to the route ahead and an indication of the speed profile on the route ahead; and output a signal indicative of the representation for provision to an output device.
