ENGINE TORQUE DETECTOR

摘要

PROBLEM TO BE SOLVED: To correctly detect an engine torque by setting an engine torque command value by a setting device, calculating an estimating value of an engine torque changing value on the basis of this command value, and controlling driving of a motor in a direction where an engine output is offset by an estimating engine torque. SOLUTION: In a hybrid vehicle of a parallel type, a clutch is released when an engine torque is detected, and an engine torque is increased/decreased in a condition in which an engine 2 is operated in a non-load condition. Namely, an engine torque command value Ste is outputted from an engine torque setting device 301, and an intake air rate Qa of an engine 2 and a fuel injection rate Tp are changed. This command value Ste is applied on an engine torque estimating device 303, an estimating value estTe of the engine torque corresponding to an engine torque changing rate by the command value Ste is found out, and a torque command value of a motor 1 which is necessary for offsetting an engine torque changing value from the value by a torque command device 304 is calculated.
