Vehicle Safety Controller for Accelerator Misoperation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-skillful drivers often accidentally operate the accelerator pedal instead of the brake pedal, leading to potential accidents, especially in situations like entering or leaving parking lots, navigating through traffic jams, or transitioning from dark to bright areas.
Innovation Solution
A device and method that utilize a detector to acquire driving, driver, and environmental information, with a controller determining whether to activate a safety driving mode based on this data. The controller assesses the vehicle's state, including road gradients, to adjust speed and gear settings, ensuring the vehicle remains in a safe mode by limiting acceleration when necessary.

Engineering Contradiction Analysis
1Speed
If the vehicle allows normal acceleration operation, then driving performance and responsiveness are improved, but the risk of accidents increases when a non-skillful driver incorrectly operates the accelerator pedal
Solution Approach 1:
The controller continuously monitors accelerator pedal operation and compares it against learned normal operation patterns for the current driving situation. When abnormal acceleration is detected (indicating possible incorrect operation), the system provides feedback by deactivating the accelerator signal and notifying the driver, thereby preventing accidents while maintaining normal performance during correct operation
Solution Approach 2:
The system learns the driver's normal accelerator operation patterns in advance during typical driving situations. This preliminary learning enables the system to distinguish between normal and abnormal acceleration requests, allowing it to prevent incorrect operations before they cause accidents while preserving normal acceleration capability
2Reliability
If the system activates safety driving mode to prevent accidents, then safety is improved, but driving freedom and normal operation are restricted
Solution Approach 1:
The safety driving mode is dynamically activated and deactivated based on real-time assessment of accelerator operation abnormality. The system transitions between normal and safety modes as needed, restricting acceleration only when abnormal operation is detected while allowing full driving freedom during normal operation, thus balancing safety and ease of operation
3Measurement precision
If the controller learns and adapts to driver behavior patterns, then accuracy in detecting incorrect operation is improved, but system complexity increases
Solution Approach 1:
The controller automatically learns and adapts to the driver's normal accelerator operation patterns through continuous monitoring and data storage, without requiring external programming or calibration. This self-learning capability improves detection accuracy over time while avoiding the complexity of manual setup or external training systems

AI summary
A device for controlling driving of a vehicle includes: a detector to acquire driving information, driver information, and surrounding environment information about the vehicle, and a controller to determine whether to activate a safety driving mode based on at least one of the driving information, driver information, and surrounding environment information about the vehicle, and to determine whether to maintain the safety driving mode state based on a vehicle state after the activation of the safety driving mode. Thus, the device may support a safety driving of the vehicle by restricting a speed of the vehicle even when the driver incorrectly operates an accelerator pedal in place of a brake pedal of the vehicle.
