1. A motor control device comprising:
a manual steering command value generation unit that generates a manual steering command value;
an integrated angle command value calculation unit that calculates an integrated angle command value by adding the manual steering command value to an automatic steering command value provided in an autonomous driving mode;
a control unit that performs angle control on an electric motor for steering angle control based on the integrated angle command value; and
a hands-on/off determination unit that determines whether a driver is in a gripping state in which the driver is gripping a steering wheel or in a released state in which the driver is not gripping the steering wheel, wherein
the manual steering command value generation unit is configured to generate the manual steering command value based on an equation of motion, and the motor control device further includes a coefficient value changing unit that changes a value of at least one coefficient among coefficients included in the equation of motion based on a determination result from the hands-on/off determination unit.
