<P>PROBLEM TO BE SOLVED: To provide an engine controller of a hybrid vehicle capable of inhibiting a driver from feeling a sense of incongruity due to a sudden change of an engine rotating speed due to a switch from a load operation of the engine to a self-sustained operation when a brake is put on. <P>SOLUTION: For controlling an engine speed of the hybrid vehicle, the engine speed is generally controlled to a value corresponding to the load operation during the load operation of the engine 1 under a load to drive a first motor generator 4. On the other hand, during the self-sustained operation of the engine 1 without the load to drive the first motor generator 4, the engine speed is controlled to the value corresponding to the self-sustained operation. However, when the engine operation is switched from the load operation to the self-sustained operation based on the change of the brake 12 from an off state to an on state during the load operation of the engine, the engine speed is controlled to the value corresponding to the load operation of the engine 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
