Vehicle Towing Recognition to Block ADAS Braking Interventions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems in vehicles trigger unwanted collision warnings or emergency braking when a vehicle is towed, disrupting the towing operation.
Innovation Solution
Recognize a towing operation by detecting vehicle acceleration after ignition activation, absence of accelerator pedal actuation, and lack of torque request, and block automatic functions that intervene in the vehicle's acceleration, deceleration, or steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems output collision warnings and emergency braking, then vehicle safety is improved, but unwanted interventions occur during towing operations
Solution Approach 1:
The system performs preliminary detection of towing situations by monitoring acceleration patterns immediately after ignition activation. By detecting the characteristic acceleration profile before normal driving operations begin, the system proactively identifies towing mode and pre-emptively disables automatic braking and steering interventions, preventing harmful interventions before they can occur.
Solution Approach 2:
The system applies preliminary anti-action by blocking automatic functions that intervene in acceleration, deceleration, or steering before they can execute unwanted maneuvers during towing. The recognition of towing operation triggers a preventive blockade of these automatic intervention functions, counteracting the potential harmful effects before they manifest.
2Object-affected harmful factors
If the ignition of the towed vehicle is deactivated to prevent unwanted warnings, then harmful interventions are avoided, but support for brake boosters and steering boosters becomes unavailable
Solution Approach 1:
The system dynamically adapts the operational state of driver assistance functions based on detected driving mode. Upon recognizing a towing situation through acceleration pattern analysis, the system dynamically switches automatic braking and steering interventions from an active state to a blocked state, while maintaining ignition and booster support in an active state. This dynamic adaptation allows the system to optimize performance for the current operational context.

AI summary
A method and an associated apparatus for recognizing a towing operation of a vehicle. A towing operation is recognized by detecting an acceleration of the vehicle immediately after activation of the vehicle ignition and at the same time detecting that there is no actuation of the accelerator pedal or no torque request from a driver assistance system. Upon recognition of the towing operation, an automatic function that intervenes in the acceleration, deceleration, or steering of the towed vehicle is blocked.
