摘要： A P-range side delimiting position of a movable range of a range change mechanism is learned by rotating a motor to a corresponding rotational position, which corresponds to the P-range side delimiting position. A climb correction amount is set for a learning value of the P-range side delimiting position to correct the learning value of the P-range side delimiting position in view of presence of a relatively small angle of rotation of the motor beyond the corresponding rotational position, which corresponds to the P-range side delimiting position. The climb correction amount is set according to motor temperature information, which is one of a temperature of the motor and a temperature that relates to the temperature of the motor.

摘要： A shift-by-wire shift switching device and shift switching method that switch a shift range of an automatic transmission using an electric motor. The shift switching device includes a controller that determines whether a fault has occurred in a current supply line of each phase of the electric motor on a phase-by-phase basis, executes an open-loop control of the electric motor using only the phases in which it has been determined that a fault has not occurred, and determines whether a fault has occurred in the current supply line by detecting an activation state of the electric motor when the open-loop control of the electric motor is executed. Therefore, it is possible to determine whether a fault in the motor is a short-circuit fault or a break fault, without addition of a part such as a short-circuit detection sensor.

摘要： A control unit learns at least one limit position in a movable range of an object to be controlled which is driven by a motor, and reduces learning time of a limit position. The control unit rotates the motor until the motor strikes the object against at least one limit position in a movable range of the object to learn the limit position. In the strike control, the control unit drives the motor first by a first duty ratio to increase the rotation of the motor toward the limit position quickly, and then by a second duty ratio lower than the first duty ratio to thereby reduce the impact load generated at the time of collision. In place of the duty ratio, a phase advance amount may be changed to reduce the impact load.

摘要： A motor controlling device includes an encoder to output pulse signals with a predetermined angle interval as a rotor of a motor is rotated. An energized phase of the motor is sequentially switched by detecting a rotation position of the rotor based on a value of counting the signals. An initial drive controlling portion executes an initial drive to switch the energized phase with a predetermined pattern after the device is activated so as to learn a relationship among the count value, the rotation position and the energized phase. An initial drive prohibiting portion prohibits the execution of the initial drive until a predetermined time is elapsed after the initial drive is finished.

摘要： An engine ECU 200 includes a bandpass filter (1), a bandpass filter (2), and a bandpass filter (3). The bandpass filter (1) extracts only vibrations at a first frequency band A from the vibrations detected by a knock sensor. The bandpass filter (2) extracts only vibrations at a second frequency band B from the vibrations detected by the knock sensor. The bandpass filter (3) extracts only vibrations at a third frequency band C from the vibrations detected by the knock sensor. The first to third frequency bands A-C are identical in bandwidth. The engine ECU calculates a peak value in magnitude of vibrations in a synthesized waveform of these frequency bands, and determines whether knocking occurred or not based on the peak value.
