Title: On-vehicle control device
Inventor: NAKAGAWA HIRONARI
IPC: F02M25/08
Filed: 2002-06-04
Abstract: <P>PROBLEM TO BE SOLVED: To maximize the opportunity of detecting the leakage or misfire of a fuel gas while preventing errors in detection.  <P>SOLUTION: During detecting the leakage of the fuel gas, a gas exhaust passage is put in a closed condition and the occurrence or not of the leakage of the fuel gas in the gas exhaust passage is detected from a change in pressure after introducing predetermined negative pressure. An ECU 30 detects the fluctuation of an oil surface in a fuel tank 14 and it establishes the starting conditions of detecting the leakage when the fluctuation of the oil surface is smaller than a preset determination level. The ECU 30 acquires future travel road surface information for a vehicle from a navigation device 40 and changes the starting conditions of detecting the leakage depending on the acquired travel road surface information.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a CDMA wireless system capable of controlling transmission power in accordance with a radio wave propagation environment.  <P>SOLUTION: An MS (mobile station) 20 (BTS 10) transmits a transmission signal representing a first frame by a first transmission power. The BTS 10 (MS20) receives the transmission signal as a received signal. The transmission and received signals include a plurality of pilot bits whereby the BTS 10 (MS20) takes synchronization of the first frame and a transmission power control bit whereby the BTS 10 (MS20) requests the adjustment of a second transmission power when the BTS 10 (MS20) transmits the second frame to the MS20(BTS10). When a radio wave propagation environment on a wireless communication channel between the BTS 10 and the MS 20 is bad, an error occurs in a result when the BTS 10 (MS20) receives the received signal and demodulates / decodes the received signal. When the transmission power control bit requests reduction in the second transmission power, the BTS 10 (MS20) calculates a degree of coincidence denoting the coincident degree between the transmission and the received signals on the basis of a plurality of the pilot bits, compares the degree of coincidence with a prescribed value, and decreases the second transmission power on the basis of the result of comparison to transmit the second frame to the MS20(BTS10).  <P>COPYRIGHT: (C)2004,JPO
