Abstract: In a rotation detecting apparatus, a sensor includes a sensor element outputting a measurement value representing rotation of a detection target, and a circuit module. The circuit module includes a rotational angle calculator calculating, based on the measurement value, rotational angle information indicative of a rotational angle of the detection target. The rotational angle calculator generates a rotational angle signal including the rotational angle information. The circuit module includes a rotation number calculator calculating, based on the measurement value, rotation number information representing the number of rotations of the detection target. The rotation number calculator generates a rotation number signal including the rotation number information. An output unit outputs, as an output signal, a series of the rotational angle signal and the rotation number signal. A controller obtains the output signal from the communicator, and calculates, based on the output signal, information about the rotation of the detection target.

Abstract: A communication system includes a sensor apparatus transmitting a sensor signal including detection information of a detection target as a digital signal and a microcomputer receiving the sensor signal through a signal line and performing a control operation at a predetermined operation cycle based on the sensor signal that is received. The microcomputer transmits, to the sensor apparatus, a synchronization signal which is synchronized with the predetermined operation cycle of the microcomputer. The sensor apparatus transmits the sensor signal at a predetermined constant cycle except when the synchronization signal transmitted by the microcomputer is received. The sensor apparatus changes a transmission timing of the sensor signal corresponding to the synchronization signal when the synchronization signal transmitted by the microcomputer is received.

Abstract: A rotation angle detector includes a voltage detector receiving a supply of voltage from a first power source and detecting a motor rotation regarding a motor, the motor rotation more specifically detected as (i) a rotation angle of the motor and (ii) a number of rotations of the motor. Also, a second power source is disposed separately from the first power source and supplying voltage to the voltage detector. Thus, even when the voltage of the in-vehicle battery lowers or the voltage supply therefrom is interrupted, the voltage supply to a voltage detector is continuous from the power storage device, thereby enabling a continuous detection of the rotation angle and the rotation number of the motor.

Abstract: A rotating electric machine driver apparatus and an electric power steering apparatus using the same includes a controller section that obtains a detected current value and generates a high-side instruction signal and a low-side instruction signal to switch an upper arm element and a lower arm element based on the detected current value. An abnormality detector determines a simul-OFF abnormality which is an abnormality of a pair made up of the high-side and low-side instruction signals being simultaneously switched off based on a condition that switching off of the high-side instruction signal for the upper arm element and the low-side instruction signal for the lower arm element pair continues for at least a simul-OFF abnormality determination time. In such manner, the simul-OFF abnormality of the instruction signals is detected.

Abstract: A torque sensor has a magnetic sensor, which is composed of a first magnetic detecting element, a second magnetic detecting element and a comparator. The first magnetic detecting element outputs an output signal of a provisional detection value, while the second magnetic detecting element outputs an output signal of a reference value. The comparator compares the provisional detection value and the reference value and outputs the provisional detection value as an authorized detection value, when a difference value between the provisional detection value and the reference value is smaller than a predetermined threshold value.
