Vehicle Dynamics Control System Using Surroundings Sensor Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle dynamics control systems, such as ESP, may not adequately minimize collision risk when drivers fail to activate or incorrectly assume the system is active, leading to increased accident likelihood due to insufficient vehicle control.
Innovation Solution
A control system that detects objects in the vehicle's surroundings, determines the probability of interaction, and adjusts the intensity of control interventions, including activation or deactivation of the vehicle dynamics control system, to prevent lateral breakaway and minimize collision risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver manually activates or deactivates the vehicle dynamics control system, then the driver has control over system operation, but the collision risk increases when the driver fails to activate or incorrectly assumes the system is active
Solution Approach 1:
The vehicle dynamics control system automatically determines whether to activate or deactivate based on detected objects and interaction probability, eliminating dependence on driver action. The system serves itself by using sensor data to make activation decisions without requiring driver intervention
Solution Approach 2:
The system continuously monitors surroundings using detection devices, evaluates collision risk based on object position and vehicle dynamics, and adjusts system activation accordingly. This closed-loop feedback ensures the system remains active when collision risk is high
2Reliability
If the vehicle dynamics control system continuously monitors and adjusts control interventions, then the collision risk is minimized, but the driving experience is degraded by noticeable control interventions
Solution Approach 1:
The control intervention intensity is dynamically adjusted based on the determined interaction probability. When collision risk is low, interventions are minimal or nonexistent, providing a natural driving experience. When risk increases, intervention intensity increases accordingly
Solution Approach 2:
The system changes the parameter of control intervention intensity as a function of interaction probability. By adjusting this parameter continuously rather than using fixed thresholds, the system achieves smooth transitions that are less noticeable to the driver while maintaining safety
3Adaptability or versatility
If the control system adjusts intervention intensity based on multiple operating modes, then the system adapts to different driving situations, but the device complexity increases
Solution Approach 1:
The control system uses a universal probability threshold evaluation mechanism that works across multiple operating modes. The same core logic of determining interaction probability and adjusting intervention intensity applies regardless of the specific mode, reducing overall system complexity while maintaining adaptability

AI summary
A method for operating a control system for dynamics control of a vehicle, in particular a motor vehicle, which includes: detecting an object with the aid of at least one surroundings detection device which detects a detection area in the vehicle surroundings, determining the probability of an interaction, between the vehicle and the object, to cause damage to the vehicle or its occupants, and changing the intensity of a control intervention by the vehicle dynamics control system as a function of the previously determined probability of an interaction between the vehicle and the object in at least one operating mode of the control system, the vehicle dynamics control system being a vehicle dynamics control system for preventing a lateral breakaway of the vehicle. Also described is a corresponding control unit and control system.
