Rear Camera Towing Mode Control for Tow Rope Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Towing operations by private individuals can be dangerous due to driver overwhelm and potential mistakes, especially when the tow cable is under tension, leading to uncontrolled steering and braking interventions.
Innovation Solution
A rear-view camera system that detects the condition of the tow rope and activates towing mode, adjusting the vehicle speed to a predefined towing speed, informing the driver visually and acoustically, and automatically terminating the mode based on rope tension or slack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver manually controls the towing vehicle, then the driver can respond to the towing situation, but the driver may make uncontrolled steering and braking interventions when the cable is under tension, leading to dangerous situations
Solution Approach 1:
The system enables the towing vehicle to control itself automatically during towing operations. The control unit detects towing conditions through sensors and autonomously adjusts driving parameters without requiring manual driver intervention, thereby preventing dangerous uncontrolled steering and braking while maintaining operational responsiveness
Solution Approach 2:
The system continuously monitors towing conditions using sensors that detect cable tension, vehicle position, and operational state. This feedback is processed by the control unit, which automatically adjusts the vehicle's driving behavior in response to detected conditions, creating a closed-loop control system that enhances safety while preserving driver awareness
2Speed
If the vehicle speed is not restricted during towing, then the vehicle can maintain normal driving performance, but the towing operation becomes unsafe due to potential jerking loads and loss of control
Solution Approach 1:
The system dynamically adjusts the vehicle speed based on detected towing conditions. The control unit automatically modifies speed parameters in real-time according to the towing state, allowing the vehicle to maintain optimal performance during towing while preventing excessive speeds that could cause jerking loads or loss of control
Solution Approach 2:
The system changes key operating parameters including maximum speed limits, acceleration rates, and braking force when towing conditions are detected. These parameter modifications are automatically applied by the control unit to ensure safe towing operations while preserving normal driving characteristics when towing is not required
3Extent of automation
If a camera system is added to detect towing conditions, then automatic towing mode activation is possible, but the device complexity increases
Solution Approach 1:
The camera system is designed to serve multiple functions: detecting towing conditions, monitoring the towed object, and providing visual feedback to the driver. By making the camera multi-functional, the system achieves automatic towing mode activation without proportionally increasing overall system complexity, as the same hardware performs multiple detection and monitoring tasks

AI summary
The invention relates to a method for carrying out a towing operation of a towing vehicle (10) comprising the steps: activation of a towing mode (S1) and adjustment of a vehicle speed to a towing speed (S2). Furthermore, the present invention relates to a camera system (100) for detecting a towing operation, comprising at least one camera (12) arranged at the rear of a vehicle, in particular a reversing camera, for capturing at least one partial area located behind the vehicle (10); and an image processing device (16) configured to detect a towing device (14) in the captured image data, thereby enabling the activation and/or termination of a towing mode.
