Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging for driving instructors to quantify and assess the driving skills of student drivers in real-time during live sessions, making it difficult to provide effective feedback and monitor improvements.
Innovation Solution
A computer system equipped with sensors and a user interface that gathers data on student driver behavior, acceleration, braking, and steering, generating reports with scores based on this data and instructor comments, displayed in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a driving instructor manually observes and assesses student driver performance during live sessions, then the instructor can provide real-time guidance and feedback, but it becomes difficult to objectively quantify and measure driving skills
Solution Approach 1:
The patent replaces the manual mechanical observation system with an automated electronic sensing system. Sensors detect driving parameters such as steering angle, acceleration, braking force, and mirror checking frequency, converting subjective instructor assessment into objective quantitative data that can be precisely measured and analyzed.
Solution Approach 2:
The patent introduces a computer system as an intermediary between the student driver and the instructor. This intermediary collects data from multiple sensors, processes the information, and generates performance reports, thereby bridging the gap between raw driving actions and meaningful performance evaluation while reducing the cognitive load on the instructor.
2Measurement precision
If multiple sensors are deployed to collect comprehensive driving data, then measurement precision improves, but device complexity and cost increase
Solution Approach 1:
The patent employs sensors that serve multiple functions within the driving assessment system. For example, the steering angle sensor not only measures steering input but also indirectly provides information about lane positioning and turning maneuvers. The acceleration sensor detects both longitudinal acceleration and braking events, reducing the need for separate dedicated sensors for each function.
Solution Approach 2:
The patent combines multiple sensing functions into integrated sensor units and consolidates data processing in a single computer system. By merging the collection and initial processing of data from various sensors into unified components, the system reduces overall complexity while maintaining comprehensive measurement capabilities.

AI summary
A method includes, during a driving session in which a student driver operates a vehicle, gathering driving skill data indicative of at least one of behavior of the student driver, acceleration of the vehicle, braking of the vehicle, or steering of the vehicle, and gathering comments from a driving instructor about the driving session. The method also includes generating a driving session report corresponding to the driving session. The driving session report includes at least one score based on the driving skill data, and the comments from the driving instructor about the driving session. Still further, the method includes causing the driving session report to be displayed on a display device.
