Title:
MOTOR CONTROL DEVICE AND MOTOR CONTROL METHOD
Document Type and Number:
Japanese Patent JP2016158308
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive motor control device and motor control method for reducing a load on a person without using a sensor in acquiring the information of a drive system.SOLUTION: A motor control device 80 and a motor control method are constituted to calculate the value Fxs of man power to work on a vehicle 10 on the basis of an inter-terminal voltage U of a motor 12 and a current value I of a current flowing down the motor 12. The motor 12 is controlled based on the man power Fxs. Consequently, an expensive sensor for acquiring the information of a drive system such as a torque sensor is not required so as to extremely inexpensively configure the motor control device 80 to be used in an electrically-driven assist device. Thus, the electrically-driven assist device for automatically controlling the torque of the motor in response to a load is extremely inexpensively provided.SELECTED DRAWING: Figure 1
