Adaptive Cruise Control Tap Input for Dynamic Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle assistance systems for longitudinal guiding, such as adaptive cruise control, often fail to utilize available space for dynamic maneuvers, leading to slow driving sensations that do not align with driver preferences due to system limitations and delayed reactions.
Innovation Solution
A method and system that monitors brief activations of an operating element, such as an accelerator pedal, to dynamically increase driving dynamics without manual takeover, allowing for intuitive and immediate adjustments to driving situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If assistance systems use conventional safety-orientated standard settings, then system reliability is improved, but driving dynamics and reaction time deteriorate
Solution Approach 1:
The system dynamically adjusts driving behavior based on detected situations. When a touching input is detected, the system transitions from conservative safety-oriented control to more dynamic acceleration profiles, allowing faster reaction times and improved driving dynamics while maintaining reliability through controlled transitions between operating modes
Solution Approach 2:
The system changes key parameters such as acceleration rates and response thresholds based on detected driver intent. By modifying acceleration parameters from conservative to aggressive profiles when touching is detected, the system improves driving dynamics and reaction speed without compromising overall system reliability
2Reliability
If assistance systems respond conservatively to driver inputs, then system safety is improved, but driver satisfaction and perceived responsiveness deteriorate
Solution Approach 1:
The system adapts its responsiveness dynamically based on the type of driver input detected. Conservative safety-oriented responses are used for standard inputs, while more responsive and dynamic responses are activated when touching behavior is detected, thereby improving driver satisfaction without compromising system safety
Solution Approach 2:
The system continuously monitors driver input patterns and adjusts its response characteristics accordingly. By detecting touching behavior as feedback from the driver, the system modifies its acceleration and response profiles to better match driver expectations, improving perceived responsiveness and satisfaction while maintaining safety through controlled adjustments
3Ease of operation
If automated longitudinal guiding controls speed automatically, then ease of operation is improved, but driver ability to adjust driving dynamics deteriorates
Solution Approach 1:
The system provides self-service by automatically detecting driver intent through touching patterns and adjusting driving dynamics without requiring manual intervention. This maintains the ease of automatic speed control while restoring adaptability, as the system serves itself by interpreting driver inputs and modifying acceleration profiles accordingly
Solution Approach 2:
The system uses feedback from driver touching inputs to automatically adjust driving dynamics. By monitoring and interpreting touching patterns as feedback signals, the automated longitudinal guiding system can adapt its acceleration behavior to match driver preferences, combining the ease of automation with the versatility of manual adjustment

AI summary
A method and an assistance system for adjusting driving dynamics of a motor vehicle including, monitoring actuations of a control element in an operating mode comprising at least assisted longitudinal control, in which operating mode the speed of the motor vehicle is controlled by a vehicle guidance system. Only when such a detected actuation of the control element is identified as tapping, the driving dynamics for the longitudinal control are then automatically increased in a predefined manner at least for the current driving situation at that time. The at least assisted longitudinal control of the motor vehicle by the vehicle guidance system remains active in the process.
