Pedal Misapplication Warning Logic for Faster Driver Release Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems fail to effectively guide drivers to decelerate their vehicles promptly after a pedal misapplication operation, as current warning methods, such as buzzer alerts and display instructions, do not clearly convey the error, leading to potential sudden vehicle acceleration.
Innovation Solution
A driver assistance device and method that determine a pedal misapplication condition and output a warning display and audio directly instructing the driver to release the depressed pedal, using a combination of visual and auditory cues, including an attention-attracting illustration and audio message, to quickly correct the pedal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a warning buzzer is used to attract driver attention, then the driver is alerted to the pedal misapplication, but the driver is not effectively guided to release the accelerator pedal and decelerate the vehicle
Solution Approach 1:
Instead of instructing the driver to depress the brake pedal (the intended correct action), the system inverts the instruction to directly tell the driver to release the currently depressed accelerator pedal. This inversion simplifies the driver's cognitive processing by focusing on the immediate error correction rather than the intended correct operation, thereby improving response effectiveness while maintaining detection reliability.
Solution Approach 2:
The warning message is tailored to the specific local condition detected - when the accelerator pedal is depressed without brake pedal depression. The system provides a localized instruction specific to this error state rather than a generic warning, making the guidance more effective for the specific misapplication scenario while maintaining overall system reliability.
2Loss of information
If text messages and illustrations are displayed to instruct the driver to depress the brake pedal, then information is provided to the driver, but the driver takes considerable time to read and comprehend the message
Solution Approach 1:
The system extracts only the essential information needed for immediate correction - the instruction to release the accelerator pedal - and presents it in a simplified format. By taking out only the critical action required rather than providing comprehensive driving instructions, the system reduces information processing time while maintaining effective communication of the error state and required correction.
Solution Approach 2:
The instruction is inverted from the intended correct action (depress brake) to the immediate corrective action (release accelerator). This inversion reduces the cognitive steps required by the driver, as releasing a pedal is more instinctive and faster than learning to press a different pedal, thereby reducing response time while maintaining information delivery.
3Ease of operation
If the system instructs the driver to depress the brake pedal, then the driver is guided to perform the correct operation, but the driver may not recognize that he/she is erroneously depressing the accelerator pedal
Solution Approach 1:
The system inverts the instructional approach by telling the driver what to stop doing (release accelerator) rather than what to start doing (depress brake). This inversion directly addresses the driver's current erroneous state, making the error recognition implicit in the correction instruction, thereby maintaining ease of operation while improving error state comprehension.
Solution Approach 2:
The warning message provides immediate feedback about the detected pedal misapplication state. By linking the instruction to release the accelerator with the detected error condition, the system creates a feedback loop that helps the driver understand the error state through the corrective action required, enhancing both guidance effectiveness and error comprehension.

AI summary
A driver assistance device includes a one or more processors. The one or more processors is configured to determine whether a pedal misapplication determination condition is satisfied, and output, when the one or more processors determines that the pedal misapplication determination condition is satisfied, at least one of a warning display and warning audio directly instructing a driver to release the pedal that is depressed at a point in time of outputting.
