Driver Assistance System Emergency Braking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems face challenges in reliably detecting and responding to health-related emergencies, particularly in situations where the driver is unable to control the vehicle, leading to potential accidents and loss of mobility for seniors and others with health restrictions.
Innovation Solution
A driver assistance system with an electronically controllable braking system and a control unit connected to an operating element that allows for manual initiation of automatic braking functions, including emergency braking, without relying on vital data analysis, enabling a front passenger to intervene and safely stop the vehicle by actuating the operating element, which can be combined with tracking and autonomous driving features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If automatic braking function is initiated independently of brake pedal actuation, then response time in health-related emergencies is improved, but device complexity increases due to electronically controllable braking system and control unit integration
Solution Approach 1:
The system enables self-service by automatically initiating braking actions without requiring driver input through the brake pedal. The control unit autonomously activates the electronically controllable braking system when health-related emergencies are detected, eliminating the need for manual driver intervention and significantly reducing response time.
Solution Approach 2:
The control unit serves as an intermediary between the health monitoring sensors and the braking system. It receives data from sensors monitoring driver health parameters, processes this information, and automatically activates the braking system when emergency conditions are detected, bridging the gap between health monitoring and safety intervention.
2Reliability
If operating element requires continuous actuation beyond predefined minimum duration for emergency braking, then false activation is reduced, but ease of operation deteriorates requiring sustained manual input
Solution Approach 1:
The system uses periodic action by requiring the operating element to be actuated continuously for a predefined minimum duration before triggering emergency braking. This time-based threshold distinguishes between accidental or momentary inputs and intentional emergency activation, preventing false activation while maintaining operational reliability.
3Measurement precision
If tracking system is activated simultaneously with emergency braking, then vehicle localization precision is improved, but use of energy increases due to additional sensor and processor requirements
Solution Approach 1:
The tracking system is activated simultaneously with emergency braking to provide immediate and accurate vehicle localization data for emergency response. By initiating the tracking function at the same time as the braking maneuver, the system ensures precise localization information is available without delaying the critical braking response.

AI summary
A driver assistance system in a motor vehicle includes an electronically controllable braking system and a control unit assigned to this braking system and connected with an operating element also assigned to the braking system. The operating element, when correspondingly actuated, can initiate an automatic braking function in the form of a normal braking by use of the electronically controllable braking system independently of the actuation of the brake pedal. The control unit is operatively configured such that, when the operating element is continuously actuated beyond a predefined minimum duration, an emergency braking function can be initiated.
