An electric motorcycle comprises a motor case which is provided at a rear portion of a vehicle body frame; a swing arm which is pivotably coupled at its front end portion to the rear portion of the vehicle body frame; and a rear suspension coupled to the vehicle body frame and the swing arm. The spatiotemporal locator information represents a spatiotemporal area which is a temporal transition of an object region over a plurality of frames. The controller is configured to determine an impending inoperability of the first thyristor based on the first current and alert a user if the first current indicates the impending inoperability. In a further embodiment, a reference voltage for reading the second plurality of MLCs is set according to the adjust code.
