Abstract
A vehicle has a drive wheel, a seat, an attitude sensor, a balancer movable relative to the seat, a drive control, an attitude control for controlling the attitude of the seat by moving the balancer and a main controller. The main controller calculates a torque Tfor tilting the seat and a torque Tfor moving the balancer forward, compares Twith Tmax (the maximum torque which can be generated by the balancer), and outputs commands to the drive control and the attitude control. When the calculated torque Texceeds Tmax, responsive to a command for Tmax, the attitude control moves the balancer to generate a reaction torque corresponding to Tmax, and the main controller supplies an adjustment torque value Tfor the drive wheel. The drive control controls the drive wheel in accordance with the drive command and the adjustment torque value T
