Abstract: In an altimetric compensation apparatus and method for a speed change pattern of an automatic transmission, first to third memory locations corresponding respectively to idling, low load and highload conditions of an engine are provided. A feedback air fuel ratio is calculated on the basis of feedback signals from an air fuel ratio sensor. A value in the memory corresponding to the detected running condition of the engine is compensated on the basis of deviation of the feedback air fuel ratio from the base air fuel ratio. When the values in at least two memory locations deviate by at least a predetermined value from the base value, the altimetric compensation value is adjusted and the speed change pattern is altered on the basis of the altimetric compensation value thus obtained.

Abstract: An IG-off-timer measures the time t_off from when an engine is stopped, or an ignition is turned off. An ECU sequentially memorizes an estimated temperature of each of heat generating portions as a memorized temperature. Immediately after the engine is re-started, the ECU sets an initial value of the estimated temperature of each heat generating portion in such a manner that the initial value reflects a temperature drop of the heat generating portion in the deactivation period of the engine. The temperature of the heat generating portion is thus accurately estimated even after re-starting of the engine. The heat generating portions are thus appropriately protected.

Abstract: The drive control of the invention executed in a vehicle sets a correction coefficient keg, based on an intake air temperature and an atmospheric pressure reflecting the density of intake air supplied to an engine, and multiplies a power demand required for the vehicle by the set correction coefficient keg to specify a target engine power, which is to be output from the engine. The engine and two motors are then controlled to ensure output of the specified target engine power from the engine and output of a torque demand, which depends upon an accelerator opening. The varying density of the intake air may cause output of excessive power from the engine or output of insufficient power from the engine. A battery is charged or discharged to compensate for the excessive power output from the engine or for the insufficient power output from the engine. The drive control of the invention effectively deals with the environmental change and prevents the battery from being excessively charged with an unexpectedly high electric power or from being excessively discharged to supply an unexpectedly high electric power.

Abstract: A method for controlling a drive train of a motor vehicle, to a method for controlling a clutch device, and to a drive train of a motor vehicle, the drive train being operated in a normal load operation, in which the internal combustion engine moves the motor vehicle against the resistances opposing the movement of a motor vehicle, the play in the load direction pre-determined by the rotary direction of the motor output shaft being closed. The drive train (40) operating outside normal load operation is operated under pre-determined conditions in a second operating mode in which a first load is introduced into a drive train section, causing the play at the drive-end of the load introduction point to be closed or to remain closed, the first load being such that it would not be sufficient to overcome the resistances opposing the movement of the motor vehicle in the plane.

Abstract: A duty jumping amount at an actual shift-begin point (SB point) during static shifting is calculated dependent on an automatic transmission fluid temperature and a turbine torque.
