Abstract: PROBLEM TO BE SOLVED: To solve the problem that it is difficult to acquire information on the electrical angle of a multi-phase rotary machine with high accuracy, based on the comparison between the induced voltage of the multi-phase rotary machine and a reference voltage. SOLUTION: Comparison signals PU, PV, and PW are obtained by comparing terminal voltages vu, vv, vw of a brushless motor with the reference voltage vref on the basis of the magnitude relation. Based on the coincidence between a 3-bit signal (composite signal PS), obtained by logically synthesizing the comparison signals PU, PV, PW and a composite signal (expectation signal) assumed when a zero-cross timing is detected in the operating state of a switching element, a detection signal Qs at the zero-cross timing is inverted.

Abstract: PROBLEM TO BE SOLVED: To solve the problem wherein it is difficult to discriminate between an abnormal state, where it is difficult to control a rotational state and a rotational ripple state caused by load ripple, etc. , based on the zero-cross timing, when induced voltage is based on the timing that is detected on the terminal voltages vu, vv and vw of a brushless motor 10 and the reference voltage vref that cross zero.

Abstract: PROBLEM TO BE SOLVED: To restore drive control without stopping the rotation of a motor at a stage before a brushless DC motor driven by a sensorless system comes to a complete step-out. SOLUTION: A step-out monitoring circuit 7 of a motor driving device 1 detects a sign that the brushless DC motor 2 is on the verge of shifting to a step-out state by monitoring the rotation state of the motor 2. When such a sign is detected, the motor is controlled in such a way that a conduction control circuit 4 stops driving the motor 2 temporarily to put it into a free running state before resuming the drive of the motor 2.

Abstract: PROBLEM TO BE SOLVED: To keep operation of an auto-levelizer stable even when a system is in an unstable condition in the auto-levelizer for onboard equipment. SOLUTION: A microcomputer 4 adjusts and controls the optical axis of a head lamp 1 based on a vehicle height value detected by a vehicle height sensor 3 during normal operation. When a voltage of electric power supplied to the microcomputer 4 through a microcomputer power supply circuit 10 is lower than a predetermined voltage, an adjustment section 7 puts a transistor 16 in an off state and a transistor 14 in an on state and sets a DC drive signal of a drive circuit 5 at 0 [V]. This allows the optical axis of the head lamp 1 to be adjusted and controlled to a reference position for the lowest beam. COPYRIGHT: (C)2006,JPO&NCIPI
