Abstract
A control unit controls a vehicle having a body to allow a user to step on, a power generator arranged to generate power that drives the body, and a first sensor and a second sensor. Each sensor preferably outputs a load value representing a load that has been applied to the body. The control unit preferably includes a processor arranged to output a command value associated with a bias of the load based on first and second load values that have been respectively detected by the first and second sensors, and a drive controller arranged to control the power generator in accordance with the command value.
