<p>A vehicle is provided with a human power detector (a torque sensor (16)) and a zero-point setting device (27) that sets a zero-point setting value of the human power detector. An auxiliary driving power generation device (21) is further provided to generate auxiliary driving power in accordance with a magnitude of the human driving power. The zero-point setting device (27) is set to have an initial setting unit (24), a minimum value detection unit (25) and a zero-point setting value correction unit (26). When a measuring value fluctuates within a predetermined period of time after turning an electric power source on, the initial setting unit (24) sets either the maximum value of the measuring values or the maximum value of zero-point setting values determined in advance to the zero-point setting value. The minimum value detection unit (25) detects the minimum value of the measuring values detected by the human power detector. The zero-point setting value correction unit (26) repeatedly carries out subtraction of the zero-setting value for every waiting period determined in advance so as to reduce the zero-setting value to the minimum value.</p> |
