Abstract
A vehicle includes: a battery; an electric motor to be actuated by electric energy stored in the battery; a switch coupled between the battery and the electric motor; an inertial sensor configured to output an acceleration signal; a controller configured to output a pulse width modulation (PWM) signal having a duty ratio according to an acceleration magnitude of the acceleration signal; and a switch driving circuit configured to generate a control current for controlling the switch based on the PWM signal.
