A method for controlling an actuatable safety device for protecting an occupant of a vehicle includes utilizing an advanced driver assistance system (ADAS) to determine that a vehicle collision is impending. In response to determining the existence of an impending vehicle collision, a mass spring damper model uses sensed vehicle longitudinal acceleration (IMU_X) to estimate the occupant movement that will result from the impending vehicle collision. The estimated occupant movement is used to determine how to control deployment of an actuatable safety device in response to the crash.

It is an object of the present invention to provide an electric brake device capable of accurate control at low cost. The present invention includes a motor control device 11 that controls rotation of an electric motor 8 for pressing brake pads 5a, 5b. The motor control device 11 is provided with: a motor position-current relationship generation portion 43 that acquires a relationship between the rotational position and the current of the electric motor 8; a braking torque estimation portion 41 that estimates braking torque pressing the brake pads 5a, 5b, on the rotational position of the electric motor 8; and a braking torque-position relationship portion generation portion 42 that acquires a relationship between the rotational position and the braking torque of the electric motor 8 on the basis of information from the motor position-current relationship generation portion 43 and the braking torque estimation portion 41. The rotation of the electric motor 8 is controlled on the basis of information from the braking torque-position relationship portion generation portion 42.
