Student Driver Parking Assist for Unintentional Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems do not effectively prevent unintentional acceleration by inexperienced drivers, particularly in situations like parking maneuvers, which can lead to collisions.
Innovation Solution
A vehicle control system equipped with sensors and an electronic control unit (ECU) that processes sensor data to detect when a vehicle is undertaking a parking maneuver and limits acceleration if it determines the acceleration is unintentional, especially when the system is in student driver mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle control system limits acceleration during parking maneuvers in student driver mode, then the safety and reliability of the vehicle is improved, but the ease of operation and driver control is worsened
Solution Approach 1:
The system dynamically adjusts acceleration limits based on the detected maneuver type. During parking maneuvers, acceleration is restricted to prevent unintentional movement, while during normal driving operations, full acceleration control is maintained. This dynamic adaptation resolves the contradiction by applying restrictions only when and where safety risks exist.
Solution Approach 2:
The control system changes the acceleration parameter thresholds based on the operational context. When a parking maneuver is detected through sensor data analysis, the system modifies the acceptable acceleration range to near-zero values, effectively preventing unintentional acceleration while maintaining normal operational parameters during non-parking scenarios.
2Measurement precision
If the system monitors and determines unintentional acceleration during parking maneuvers, then the measurement precision and detection accuracy is improved, but the device complexity and processing requirements is worsened
Solution Approach 1:
The detection process is segmented into distinct phases: sensor data acquisition, maneuver type classification, acceleration intent determination, and control response. By dividing the complex monitoring task into discrete analytical steps, the system achieves high detection precision without overwhelming processing requirements, as each segment handles a specific aspect of the analysis.

AI summary
A vehicular control system includes a sensor disposed at a vehicle and sensing exterior and at least forward of the vehicle. The vehicular control system is operable in a student driver mode. The vehicular control system, responsive to processing the sensor data, determines when the vehicle is undertaking a parking maneuver. The vehicular control system, responsive to determining that the vehicle is undertaking a parking maneuver and when the vehicular control system is operating in the student driver mode, determines when an acceleration of the vehicle is unintentional. The vehicular control system, responsive to determining that the acceleration of the vehicle is unintentional, limits acceleration of the vehicle.
