<P>PROBLEM TO BE SOLVED: To provide a controller for a hybrid vehicle, suppressing a start frequency of an engine when an engine start request is performed during traveling in an electric automobile travel mode. <P>SOLUTION: In the parallel hybrid vehicle having a first clutch CL1 disconnecting/connecting the engine Eng from/with a motor/generator MG, when target drive torque Td<SP>*</SP>of the vehicle becomes larger than a cranking request decision threshold value T<SB>d_th_A</SB>during the traveling in the "EV mode", the first clutch CL1 is fastened, and the engine Eng is cranked. When the target drive torque Td<SP>*</SP>becomes larger than an engine start request decision threshold value T<SB>d_th_B</SB>that is a value larger than the cranking request decision threshold value T<SB>d_th_A</SB>, the engine Eng is started. <P>COPYRIGHT: (C)2010,JPO&INPIT |
