Patent attributes
An accelerator pedal system that controls a reaction force of an accelerator pedal in a case that a vehicle speed exceeds a predetermined speed includes: a vehicle speed sensor; an accelerator pedal connected to a rod having a predetermined shape; a switch that generates a signal corresponding to at least one predetermined speed limit and a selected mode among a plurality of predetermined modes; an engine management system that receives signals from the vehicle speed sensor and the switch; an accelerator pedal position sensor that detects an operating position of the accelerator pedal and generates a corresponding signal; a pedal control unit that receives a vehicle speed signal and a switch signal from the engine management system, and outputs a control signal when a vehicle speed exceeds the speed limit; and a reaction device that is disposed to an upper portion of the accelerator pedal, and that, in response to the control signal of the pedal control unit, generates a reaction force depending on the selected mode, and applies the generated reaction force to the accelerator pedal. By the accelerator pedal system of the present invention a driver can drive a car with more safety.
