A hybrid vehicle 20 sets a tentative limit value Win0 of determining a fuel increase relation with respect to a selected gearshift position SP for driving (S220,S230,S350), and performs increasing correction of a fuel injection amount according to either a first OT increase factor setting map or a second OT increase factor setting map that is enabled based on a relation of an input limit Win of the battery 50 to the tentative limit value Win0. Prohibition of fuel cutoff may be cancelled, based on a relation of the input limit Win to a driving force demand in an accelerator-off state set at the selected gearshift position SP. Even in this case, the increasing correction enables temperature regulation of an exhaust gas purification catalyst, with a view to controlling deterioration of the exhaust gas purification catalyst in an actual fuel cutoff condition after cancellation of the prohibition of the fuel cutoff. The deterioration of the exhaust gas purification catalyst is thus favorably controlled, irrespective of the selected gearshift position SP.

An imager with a multiplexer located at the pixel output line connected to associated column sample and hold circuitry. The multiplexer ensures that signals from pixels within a column are output to the correct output channels in the readout path. By having the multiplexer at the pixel output line, before any sample and hold circuitry, the imager can use simplified column select circuitry when signals are being read out to the output channels. As such, parasitic capacitance at the readout path is reduced, which produces faster readout speeds than typical imagers. In addition, the imager achieves lower readout noise and less power consumption than typical imagers.

A digital based two wire proximity transmitter system and a method for calibrating the system, wherein the transmitter includes a customized linearization table uniquely generated during calibration to take into account the unique impedance properties of a particular probe/coaxial cable configuration. During calibration, the probe is positioned adjacent a calibration target. The calibration target is selected to have the same material characteristics as the target to be monitored during actual operation of the transmitter in the field. At a fixed distance between the probe and calibration target, the resonant frequency of the probe/cable system is determined. Thereafter, utilizing this resonant frequency to excite the probe, the voltage response of the probe/cable system is determined as the distance between the probe and the target material is incrementally changed. The voltage output is used to build a table for incremental distances, wherein each distance is characterized by a non-linear output that has been equated to a linear output. This uniquely generated table is subsequently downloaded into the transmitter for reference during monitoring.

A hybrid electronic control unit sends a combustion start command to an engine ECU when the rotation speed of an engine reaches a combustion start rotation speed by engine cranking. The engine ECU sends an initial explosion advance notification to the hybrid electronic control unit when the crank position of the engine reaches a specific position prior to an ignition timing of an initial explosion cylinder by a preset crank angle θec. Ignition of the initial explosion cylinder is performed at a timing when the crank position is further rotated by the preset crank angle θec. The hybrid electronic control unit sends a torque command in view of a counter torque Tα to a motor ECU after elapse of a preset time period tv. The preset time period tv is the sum of a first time period t1 between reception of the initial explosion advance notification and the ignition timing of the initial explosion cylinder in the engine and a second time period t2 between the ignition timing of the initial explosion cylinder in the engine and appearance of torque effect caused by the ignition of the initial explosion cylinder on a driveshaft. Such control timely reduces the torque effect caused by the initial explosion of the engine on the driveshaft.
