Driver Acceleration Notification for Time-Efficient Travel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver information systems in vehicles primarily focus on consumption efficiency and do not adequately address time-efficient driving parameters, such as optimizing acceleration to reach destinations quickly, especially when speed limits and road conditions are not recognized early enough.
Innovation Solution
A method that determines a predicted route section, calculates a reference speed based on speed limits and road conditions, and provides notifications to the driver for potential acceleration opportunities, allowing for legally and safely quick driving by evaluating geometric and dynamic properties of the road, using navigation systems and sensor data to adapt acceleration instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the driver is provided with consumption-efficient driving information based on predictive route data, then energy consumption efficiency is improved, but time efficiency in reaching the destination is not optimized
Solution Approach 1:
The notification system dynamically adapts its behavior based on the selected driving mode. In time-efficient mode, the system provides notifications that encourage higher speeds and earlier accelerations, whereas in consumption-efficient mode, it provides notifications that promote fuel-saving behaviors. This dynamic adaptation allows the same system to serve both contradictory objectives without compromise.
Solution Approach 2:
The system changes key parameters such as notification timing, speed recommendations, and acceleration suggestions based on the selected driving mode. By modifying these parameters, the system can optimize for either energy consumption or travel time, resolving the contradiction between these two opposing objectives.
2Loss of energy
If the system provides early notifications for deceleration based on predictive route data, then consumption efficiency is improved, but the driver may not perceive the need for acceleration to maintain optimal speed
Solution Approach 1:
The notification system is segmented into distinct functional components: one that provides consumption-efficient notifications (deceleration warnings) and another that provides time-efficient notifications (acceleration prompts). This segmentation allows each component to fulfill its specific information need without interfering with or diluting the other.
Solution Approach 2:
The system dynamically adjusts the type of information provided based on the driving mode selection. When time efficiency is prioritized, the system actively provides acceleration prompts and speed optimization information that would otherwise be absent, ensuring the driver receives complete information for time-optimal driving.
3Loss of time
If the driver accelerates to reach higher speeds quickly, then time efficiency is improved, but energy consumption increases
Solution Approach 1:
The notification system dynamically adapts its recommendations based on the selected driving mode. In time-efficient mode, it encourages aggressive acceleration and higher speeds to minimize travel time. In consumption-efficient mode, it recommends moderate acceleration and speed maintenance to minimize energy consumption. This dynamic behavior allows the system to support both opposing objectives without compromise.
Solution Approach 2:
The system changes critical driving parameters such as target speed, acceleration rate, and notification timing based on the selected mode. By modifying these parameters, the system enables the driver to achieve either time efficiency or energy efficiency, resolving the contradiction between these two objectives.

AI summary
A method to provide driver information in a motor vehicle includes determining a route section predicted to be driven in the future by the motor vehicle and determining a reference speed as a function of at least one specified maximum speed through a speed limit in the predicted route section or in a partial section of the predicted route section. The method further includes determining a current actual driving speed of the motor vehicle, and providing a target acceleration notification to notify a driver of the motor vehicle of a potential acceleration of the motor vehicle if the reference speed is greater than the current actual driving speed at least by a specified differential value.
