摘要： PROBLEM TO BE SOLVED: To provide an angular velocity sensor apparatus capable of offset compensation and monitoring the operation of sensors.
SOLUTION: In the angular velocity sensor apparatus of this invention, two angular velocity sensors 1 and 2 having uniform characteristics are arranged in such a way that their detecting axes may be opposed to each other at an angle of 180°, and offset components of the individual angular velocity sensors are removed from angular velocity signals by determining the output difference (subtraction) between the two sensors by an arithmetic circuit 4 to acquire highly accurate angular velocity signals. Since the output sum (addition) of the two sensors becomes only offset components (=2×OF), a reference value REF of a comparison circuit 49 is set at approximately 1.5 times a mean value (effective value) of 2×OF to compare output ADD of an addition circuit 48 with the reference value REF. By this, it is possible to simultaneously perform self diagnosis on the angular velocity sensors since (ADD-REF) is positive in the case that both angular velocity sensors are properly functioning, and (ADD-REF) becomes negative in the case that either angular velocity sensor fails, and its sensitivity and offset deviate.

摘要： PROBLEM TO BE SOLVED: To provide an angular velocity sensor system capable of effectively detecting a sensitivity error of an angular velocity sensor without bringing an excessive increase in signal processing load, and surely performing a failrue detection even in a case with low output level of angular velocity signal such as in high-speed traveling.
SOLUTION: This vehicular angular velocity sensor system 1 performs abnormality detection processing of two angular velocity sensors 2A and 2B based on comparison of output state between angular velocity signals VyA and VyB of the angular velocity sensors 2A and 2B. This system comprises a first low pass filter part removing a high-pass side unnecessary component which is unnecessary for vehicle control from the angular velocity signals VyA and VyB, and second low pass filter parts 12A and 12B having a cutoff frequency on the low-pass side therefrom. The abnormality detection processing is performed by use of low-pass side angular velocity signals VxA and VxB which were passed through the second low pass filter parts 123A and 123B.

摘要： PROBLEM TO BE SOLVED: To correct a temperature for a sensor in a short time under the condition where a quantization error is eliminated while restraining cost-up. SOLUTION: The ambient temperature of an angular velocity sensor 11 is detected as a resistance signal value proportional to the ambient temperature by thermosensitive resistances 21, 23. A selector switch 18 is switched to a fixed contact 18b side by action of a comparator 19, in a temperature higher than an ordinary temperature, and the switch 18 is switched to a fixed contact 18a side, in the ordinary temperature or less. A gradient correction voltage exhibits a voltage in response to a temperature gradient. An adder 17 calculates a detection signal of the angular velocity sensor 11, the voltage, and an amplified signal voltage and an absolute correction voltage amplified by an inversion amplification circuit 25, pursuant to prescribed expressions, and corrects them.

摘要： PROBLEM TO BE SOLVED: To make output errors generated due to changes in power source voltage small without being accompanied with increase in cost and to prevent such a state as being reduced in versatility. SOLUTION: A signal voltage Va of an absolute value level from a piezoelectric element 5 is given to an absolute voltage-ratio conversion circuit 10 through an amplification circuit 7, a filter circuit 8 and a signal correction circuit 9. The absolute voltage-ratio conversion circuit 10 converts a differential voltage between the inputted signal voltage and an absolute reference voltage VFER, which does not depend on a power source voltage to be outputted from an absolute reference voltage circuit 4 to a signal voltage, with the level thereof proportional to that of a voltage for comparison proportional to the power source voltage and gives the converted signal voltage to an A/D conversion circuit 11 provided on the system side. Voltage for comparison is obtained as the difference between the partial voltage from a voltage dividing circuit 2 for dividing the power source voltage and the partial voltage from the auxiliary voltage dividing circuit, provided inside the absolute voltage-ratio conversion circuit 10, to divide the power source voltage at a division rate differing from the voltage dividing circuit 2.
