Driver Assistance System Authorization Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems lack the ability to reliably determine whether a passenger or driver has authorized the operation, leading to potential unsafe autonomous vehicle maneuvers, and fail to monitor and alert for passenger distraction during autonomous driving.
Innovation Solution
A driver assistance system that includes a biometric recognition device and an input device to ensure only the driver can authorize operation, with sensors to monitor passenger distraction and issue warnings, allowing for safe autonomous driving with driver relaxation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver assistance system allows passenger operation, then the driver can relax during autonomous driving, but unauthorized passenger operation may compromise driving safety
Solution Approach 1:
A releasing device acts as an intermediary between the driver and the driver assistance system. The driver must actively operate this device to release the system for passenger operation, creating a deliberate authorization step that prevents unauthorized access while allowing intended relaxation
2Reliability
If biometric recognition device is used to verify driver authorization, then unauthorized passenger operation is prevented, but device complexity increases
Solution Approach 1:
The releasing device serves as a simple intermediary mechanism that physically or electronically connects the driver's intentional action to the system state change. This mediator approach provides reliable verification without requiring complex biometric systems
Solution Approach 2:
The patent offers alternative embodiments where simple mechanical or electronic releasing devices replace complex biometric recognition systems, substituting mechanical simplicity for computational complexity while maintaining adequate authorization verification
3Reliability
If the system monitors passenger distraction, then driving safety is improved, but device complexity and energy consumption increase
Solution Approach 1:
Sensors act as intermediaries that passively detect passenger state without requiring complex active monitoring systems. The sensors monitor physical parameters like position or movement to detect distraction, providing safety monitoring with minimal complexity
Solution Approach 2:
The monitoring system uses passive sensing of naturally occurring passenger physical states rather than active interrogation. The passenger's own physical movements and positions provide the monitoring data, eliminating the need for complex active monitoring mechanisms

AI summary
A driver assistance system and a method for operating a driver assistance system are disclosed. The driver assistance system includes an actuation device configured for automatically actuating a brake unit, a drive unit or a steering unit. An input device enters a user request for a driving maneuver executable by the driver assistance. A releasing device selectively releases an operation of the driver assistance system based on whether a release for the driver assistance system to be operated by the passenger of the motor vehicle is effected by the driver of the motor vehicle by means of the releasing device.
