Abstract
A drive system includes an electric motor, first and second electrical contacts, and a microcontroller configured or programmed to control an operation of the electric motor based on first and second signals regarding states of the first and second electrical contacts. After determining that a first state in which the first signal and the second signal both indicate OFF is detected, if it is determined that a second state in which the first signal and the second signal both indicate ON is detected, the microcontroller performs a control that causes the electric motor to generate motive power. If it is determined that the first state is not detected, the microcontroller does not perform a control that causes the electric motor to generate motive power, even if both of the first electrical contact and the second electrical contact take an ON state.
