Driving Support Audio Feedback for Real-Time Vehicle Stability

The patent replaces visual display (optical system) with auditory output (acoustic system) for providing driver performance evaluation information. The controller outputs sounds through a speaker based on detected driver operations, allowing drivers to receive feedback through hearing rather than sight, thus eliminating the need to visually check evaluation results while driving.

The patent introduces sound as an intermediary medium to transmit driver performance evaluation information. Instead of directly displaying visual information that requires driver attention, the system uses auditory signals as an intermediate carrier that can be perceived without visual distraction, effectively mediating between the evaluation system and the driver.

The patent applies partial action by selectively varying sound output only when necessary. The controller compares detected driver operations against reference values and only outputs varied sounds when deviations are detected, rather than continuously varying sound. This provides performance feedback while minimizing unnecessary auditory stimulation that could distract the driver.

The patent changes sound parameters (pitch, volume, type) based on driver performance deviations. When driver operations deviate from reference values, the controller modifies sound parameters to indicate the nature and direction of correction needed, providing intuitive feedback without requiring complex or continuous sound variations.
