Driver Identification via Driving Maneuver Signature Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurate driver identification is challenging due to issues like poor lighting and facial feature obstructions, and sometimes a camera is not available, making it difficult to obtain a good quality image for reliable identification.
Innovation Solution
A system that uses a processor to determine driver identification based on a driving maneuver signature, which is derived from vehicle sensor data such as steering wheel angle, gas pedal position, and acceleration, comparing it to previously stored signatures to match and identify the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If camera-based driver identification is used, then driver identification can be performed, but identification accuracy deteriorates due to poor lighting and facial feature obstructions
Solution Approach 1:
The patent replaces the optical/mechanical camera-based identification system with an electronic sensor-based system. Instead of using cameras to capture facial images, the system uses vehicle sensors (accelerometers, gyroscopes, steering angle sensors, pedal position sensors) to capture driving maneuver data, which is then processed to identify the driver based on their unique driving patterns and behaviors
Solution Approach 2:
The patent introduces driving maneuver signature as an intermediary between the driver and the identification system. Rather than directly observing the driver's physical features, the system captures indirect behavioral characteristics through sensor data (steering patterns, acceleration patterns, braking patterns) that uniquely identify the driver without requiring direct visual observation
2Reliability
If camera-based driver identification is used, then driver identification can be performed, but the system becomes vulnerable to environmental conditions and equipment availability
Solution Approach 1:
The patent makes the identification system universal by using vehicle sensors that serve multiple functions. The same sensors used for vehicle operation monitoring (accelerometers for collision detection, steering angle sensors for driver assistance) are also used for driver identification, eliminating the need for separate camera equipment and ensuring the system works regardless of lighting conditions or camera availability
3Measurement precision
If driving maneuver signature is used for identification, then identification accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by using the vehicle's existing sensor infrastructure for driver identification. The vehicle's onboard sensors, already present for other operational purposes, are leveraged to capture driving maneuver data, eliminating the need for additional dedicated identification hardware and reducing overall system complexity
Data Source
AI summary
A system for driver identification comprises a processor and a memory. The processor is configured to receive a driving maneuver signature and to determine a driver identification based at least in part on the driving maneuver signature. The memory is coupled to the processor and is configured to provide the processor with instructions.
