Title:
SHIFT RANGE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018040464
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a shift range control device which can properly control the drive of a motor related to the changeover of a shift range.SOLUTION: A feedback control part 60 of a shift range control device 40 performs feedback control based on a motor actual angle Cen being an actual angle of a motor 10 and a motor speed Msp. A fixed-phase energization control part 70 performs fixed-phase energization control for carrying electricity to a fixed phase which is selected according to an actual count value Cen. When a required shift range is switched, a changeover control part 75 brings a control state into the feedback control. Then, when an angle deviation e being a difference value between a target count value Cenwhich is decided according to the required shift range and the actual count value Cen reaches an angle determination threshold e_th or less, the changeover control part 75 switches the control state to the fixed-phase energization control from the feedback control. By this constitution, the drive of the motor 10 related to the changeover of the shift range can be properly controlled.SELECTED DRAWING: Figure 4
