  • Publication number: 20200317051
    Abstract: A kickdown switch for an accelerator pedal informs a driver of a misoperation state by using a kickdown switch provided in the accelerator pedal when the driver misoperates the accelerator pedal rather than operating a brake pedal while braking is required. Accordingly, the driver can definitely recognize the misoperation state of the accelerator pedal and rapidly stop misoperation of the accelerator pedal and sudden acceleration of the vehicle, whereby occurrence of accidents can be prevented.
