AI Technical Summary

Technical Problem

Existing accelerator pedal systems face challenges in providing precise pedal control due to decreased spatial resolution of reaction force perception, leading to driver fatigue and discomfort, especially in vehicles without mechanical engine-throttle linkage.

Method used

An accelerator pedal device that vibrates in specific frequency ranges (10 to 50 Hz and 100 to 300 Hz) to stimulate Pacinian and Meissner corpuscles, enhancing driver perception of pedal input, with amplitude adjustments based on driving modes, vehicle speed, and road conditions.

Benefits of technology

Improves pedal operation accuracy and reduces driver fatigue by stimulating skin receptors without increasing the pedal's reaction force, ensuring precise control and smooth vehicle operation even in challenging conditions.
