Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle control systems for automated longitudinal and/or transverse guidance do not allow operators to influence the guidance parameters during execution, limiting adaptability to personal safety preferences.
Innovation Solution
A control device and operator control element configuration that enables activation/deactivation of automated guidance through a first operator action and modification of driving parameters, such as velocity, via a distinct second operator action, allowing real-time adaptation of guidance during maneuvers like parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the longitudinal and/or transverse guidance is controlled solely by activation/deactivation through operator control element, then the control system is simple and reliable, but the adaptability to operator safety preferences is poor
Solution Approach 1:
The operator control element is designed to perform multiple functions: it can activate/deactivate the automated guidance system and also modify driving parameters during operation. This multi-functionality allows the system to adapt to different operator preferences without adding separate control devices, thereby improving adaptability while maintaining relatively simple system architecture.
Solution Approach 2:
The control system transitions from a static activation/deactivation mode to a dynamic mode where driving parameters can be modified in real-time during automated guidance execution. This dynamic adjustment capability allows the system to adapt to changing operator safety preferences while the maneuver is ongoing, resolving the contradiction between simplicity and adaptability.
2Ease of operation
If the operator control action is required continuously to maintain automated guidance, then the control linkage is direct and reliable, but the operator cannot influence guidance parameters during execution
Solution Approach 1:
The control functionality is segmented into distinct operations: activation/deactivation of the automated guidance system and modification of driving parameters. By separating these functions and assigning them to different control actions on the operator control element, the system allows operators to influence guidance parameters during execution without requiring continuous control input, thereby improving ease of operation while maintaining appropriate automation levels.
Solution Approach 2:
The control device acts as an intermediary between the operator control element and the automated guidance system. It receives control information from the operator, processes it, and executes appropriate actions including both activation/deactivation and parameter modification. This intermediary role enables the system to balance operator flexibility with automated guidance independence.
3Reliability
If the automated guidance executes with fixed driving parameters, then the system is simple and reliable, but it cannot adapt to real-time safety needs
Solution Approach 1:
The system incorporates feedback mechanisms where the operator can monitor the automated guidance execution and provide additional control inputs to modify driving parameters in real-time. This feedback loop allows the system to maintain reliable automated execution while adapting to real-time safety needs through operator input, resolving the contradiction between fixed parameters and real-time adaptability.

AI summary
A motor vehicle has a control device to control automated longitudinal and/or transverse guidance of the motor vehicle within the scope of a specific driving maneuver. The motor vehicle also has an operator control element to communicate with the control device and to transfer control information, relating to the at least partially automated longitudinal and/or transverse guidance, to the control device. The control device is configured in such a way that activation or deactivation of the longitudinal and/or transverse guidance can be controlled by means of an operator-side first operator-control action at the operator-control element, and at least one driving parameter which influences the longitudinal and/or transverse guidance of the motor vehicle, controlled by the control device, can be modified by means of an additional operator-side, second operator-control action at the operator-control element, which second operator-control action is in particular different from the first operator-control action.
