Abstract: A hybrid vehicle driving system includes: a generator; a motor; a case which accommodates the generator and the motor; and a power control unit for controlling the generator and the motor, the generator and the motor being disposed side by side on a same axis within the case. The power control unit is mounted on the case by connecting a unit-side generator connector and a unit-side motor connector which are provided on a bottom surface of the power control unit with a case-side generator connector and a case-side motor connector which are disposed on the case, directly and respectively. The case is fixed to a vehicle framework member via a mount member, and a fixing point where the case and the mount member are fixed together is disposed near the case-side generator connector and the case-side motor connector.

Abstract: An angular velocity measuring device (1) includes a first sensor (2) (vibration gyro) and a second sensor (3) (gas rate gyro). The detection output of the first sensor (2) is inputted to a high pass filter (4). Output of the filter (4) is stored and held in time series in a memory (10). Subtraction processing means (11) successively executes processing of subtracting the output of the filter (4) ?v?(t?tsd) before a predetermined time tsd from the output of the filter (4) ?v?(1). The value thus obtained is successively added to the output of the second sensor (3) ?g(t) by addition processing means (12) so as to obtain the measurement value of the angular velocity. Thus, it is possible to provide an angular velocity measuring device capable of giving an angular velocity measurement value having a high response and stability at a reasonable cost.

Abstract: An angular velocity measuring device (1) includes a first sensor (2) (vibratory gyroscope) and a second sensor (3) (gas rate gyroscope). A detected output of the first sensor (2) is input to a highpass filter (4) and an output of this filter (4) is stored in the time series into a memory (10). Subtraction means (11) sequentially performs operations of subtracting an output ?v?(t?tsd) of the filter (4) at a time a predetermined time period tsd earlier from an output ?v?(t) of the filter (4), and addition means (12) sequentially adds the value obtained by the above to an output ?g(t) of the second sensor (3), whereby an angular velocity measurement is obtained. Thereby, it is possible to provide an angular velocity measuring device whose angular velocity measurements are high in response and stability at a low price.
