Abstract
A motor control method for an MDPS system makes it possible to provide smoother and easier steering operation at a low cost by improving the OHP performance while supplying appropriate controlling electric current to a motor, without changing the motor or a decelerator used in an MDPS system.
Claims4
A motor control method for an MDPS system, the method comprising:
- an OHP step that decreases electric current supplied to a motor to a second electric current reduction coefficient to prevent the motor from overheating;
- and
- a Pre-OHP step that gradually decreases the electric current supplied to the motor to a first electric current reduction coefficient smaller than the second electric current reduction coefficient, before the step of OHP.
