To address the issue of novice drivers mistakenly pressing the accelerator pedal instead of the brake pedal in emergency situations, this paper designs an anti-misoperation device for the accelerator pedal specifically intended for driver training vehicles. The system collects signals of accelerator pedal acceleration and pedal force, and employs predefined logic to determine whether a misapplication has occurred. Once an erroneous operation is identified, the system cuts off the acceleration signal, activates auxiliary braking, and triggers audible and visual alarms, thereby effectively correcting driver misoperations and enhancing safety during driver training.
