Abstract:
A power assist device may include a motor, a motor driving circuit, sensors to output signals in accordance with a rotational speed of the wheel, a memory, and a signal processor. The memory stores information of a parameter defining a transfer function that interrelates a total torque to be input to the vehicle and a rotational speed of the wheel, and an inverse transfer function thereof. Based on the inverse transfer function, the signal processor determines an estimated value of total torque from a detected value of rotational speed of the wheel. Moreover, based on the transfer function, the signal processor updates at least a portion of the information of the parameter so that, for example, an error between a detected value of rotational speed of the wheel and an estimated value of rotational speed of the wheel as determined from the estimated value of total torque is reduced.

Claim (Index 8):
The power assist device of  claim 7 , wherein,\n the vehicle includes a grip, and is driven with a human force which is input via the grip; the power assist device further comprises a detector to detect whether the human force is being applied to the grip or not; and the signal processor performs the process of (5) when the detector detects that no human force is being applied to the grip.
