摘要： A controller 41 controls the torque of a front wheel drive motor 22 and a rear wheel drive motor 23, the rotation speed of a generator 21, and the torque of an engine 1. The controller 41 computes a target drive force tFv of a vehicle based on an accelerator pedal depression amount APS and a vehicle speed VSP, and divides this tFv into a target drive force tFf for the front wheels, and a target drive force tFr for the rear wheels. A power tPg required to drive the generator 21 is computed based on the target vehicle drive force tFv, and a target rotation speed tNg of the generator is computed based on this and the vehicle speed VSP. A target torque of the engine is computed from tNg and tPg.

摘要： An automatic engine-stop control apparatus for a vehicle includes a vehicle speed sensor and a brake pedal depression sensor which are coupled to a control unit. The control unit is programmed to decide that the vehicle speed detected by the vehicle speed sensor is smaller than or equal to a predetermined stop expected speed when the brake pedal depression sensor detects that the brake pedal is depressed, and to decide that the vehicle is stopped when a predetermined time period elapses from a moment that the vehicle speed becomes smaller than or equal to the predetermined stop expected speed and when the depression of the brake pedal is continued.

摘要： A power-driven hammer has a tool holder a middle bore portion which is supported inside a housing and urged backward by a compression spring. The rear end of a large bore portion of the tool holder is slidably fitted into a spline ring which is secured to the front end of a middle housing. Spline grooves are formed in the inner periphery of the spline ring at its front end while spline gears are formed on the outer periphery of the large bore portion. When the spline grooves and the spline gears are engaged with each other, the tool holder, being urged backward, is locked with its rotation prohibited. This tool holder can be temporarily unlocked to allow its rotation by sliding a change ring cover forward and the tool holder itself, thereby disengaging the large bore portion from the spline ring.

摘要： A learning or updating function which corrects the feedback control correction factor is included in a dual O.sub.2 sensor type control system. Correction related data which is used to modify in response to the output of an upstream sensor or sensor section, is recorded at memory addresses which corresponding to the sub-sections of an engine operation map. When the output of the upstream sensor changes, a sub-region in which the engine operation fell a time .tau. earlier or in which the engine operation has continuously fallen for the time .tau., is selected and the correction related data which is recorded at the corresponding address, read out, updated based in the output of the second sensor or sensor section and re-recorded at the same address.

摘要： This invention relates to an engine provided with a plurality of cylinder banks, exhaust manifolds for collecting exhaust from each bank, an exhaust branch pipe for combining the flows from the exhaust manifolds, and a three-way catalyst interposed in the exhaust branch pipe. An air-fuel ratio sensor is interposed in the exhaust manifold for each cylinder bank, and feedback control of the air-fuel ratio of each bank is performed based on the air-fuel ratio detected by the sensor of a specific bank such that this air-fuel ratio varies with a predetermined amplitude about the theoretical value as center value. The rich and lean times of the air-fuel ratio of the other banks are also measured from the output of the sensor at each bank, and feedback control is corrected for each bank such that the rich time is equal to the lean time for any bank. The number of sensors required for air-fuel ratio control of a multi-bank engine can therefore be reduced, and as the air-fuel ratio detected at the location of the three-way catalyst varies within a suitable range of tolerance, the exhaust cleaning performance of the three-way catalyst is improved.

摘要： When engine operation falls in a predetermined zone wherein it is necessary to attenuate engine surging or the like type of engine operating phenomenon, and wherein mapped adaptive update value data is required to exhibit a different resolution to the adaptive update value data which is contained in the remainder of the map not included in the predetermined zone, the operation of the engine in the predetermined zone is detected and an indication of the same set. While the indication is set, updating of the mapped data which corresponds to the predetermined operational zone, is inhibited. In some embodiments mapped data which corresponds to the predetermined operational zone is set in a separate memory section and updated in a manner different from the manner in which the data which does not correspond to the special zone, is updated.
