Driver Assistance System Maneuver Continuity via Dynamic Speed Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems for motor vehicles often abort the driving maneuver when a detected object is in the path, preventing continuation or reduction of speed, which is not necessary if the object is not impeding the path or can be bypassed.
Innovation Solution
A method that determines a driving path and automatically or semi-automatically carries out the maneuver, detecting surroundings to stop or decelerate if an object is in the path, resuming the maneuver when the object leaves or allowing bypassing, and allowing driver override for speed adjustments or abortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver assistance system aborts the driving maneuver when an object is detected in the driving path, then collision safety is improved, but the continuity and efficiency of the driving maneuver deteriorates
Solution Approach 1:
The system changes the response parameter from binary (abort/continue) to a spectrum of speed adjustments. When an object is detected in the driving path, the system modifies the speed parameter dynamically - reducing speed or stopping temporarily - rather than always aborting the maneuver. This allows the maneuver to resume automatically when the path is clear, maintaining continuity while ensuring safety.
2Reliability
If the driver assistance system continuously monitors the driving path for objects, then safety is improved, but the complexity of the system increases
Solution Approach 1:
The system employs self-service through automatic resumption of the driving maneuver. After detecting an object and executing the appropriate response (stopping or decelerating), the system automatically resumes the maneuver when the object leaves the driving path, without requiring driver intervention or complex decision-making interfaces. This simplifies the overall system architecture while maintaining continuous safety monitoring.
3Reliability
If the driving maneuver is aborted upon detection of any object, then safety is improved, but the ease of operation deteriorates as the driver cannot continue the maneuver when objects move out of the path
Solution Approach 1:
The system inverts the traditional abort logic by making continuation the default and abortion the exception. Instead of aborting the maneuver when an object is detected and requiring the driver to重新启动 it, the system automatically resumes the maneuver when the path is clear. This inversion improves ease of operation while maintaining safety through automatic monitoring and intervention when necessary.

AI summary
A method for supporting a driver of a motor vehicle during a driving maneuver, including the following: (a) determining a driving path in which the motor vehicle moves when the driving maneuver is carried out and automatically or semi-automatically carrying out the driving maneuver; (b) detecting the surroundings of the motor vehicle during the driving maneuver; (c) stopping the motor vehicle if an object is detected in the driving path and resuming the driving maneuver as soon as the object has left the driving path and/or decelerating the motor vehicle and slowly resuming the driving maneuver if an object is detected outside the driving path. Also described is a device for carrying out the method.
