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 11):
The power assist device of  claim 1 , further comprising a torque sensor to output a torque detection signal which is in accordance with the human torque, wherein,\n the signal processor\n performs one of: a process of determining the command value for motor torque based on the torque detection signal and inputting the command value for motor torque to the motor driving circuit; and the processes from (0) to (4).
