<P>PROBLEM TO BE SOLVED: To suppress uncomfortable feeling until a set vehicle speed is increased during cruise traveling and the set vehicle speed is established. <P>SOLUTION: When a set vehicle speed Vs is increased by the switch operation of a driver in a state that only a motor 2 is driven and a vehicle cruise-travels in an EV mode ("Yes" in all of S11, S13 and S16), the start of an engine 1 is prohibited by setting a prohibition flag to F<SB POS="POST">NG</SB>=1 (S29). At this time, a motor torque upper limit value TL is increased and corrected (S24, S25). When a vehicle speed V is increased to a set vehicle speed Vs ("No" in the determination of S28), and when cruise request torque Tc is smaller than a start determination threshold T<SB POS="POST">ON</SB>("No" in the determination of S36), it is determined that an acceleration period has been ended, and the motor torque upper limit value TL is returned to a normal value before the increase correction (S31). <P>COPYRIGHT: (C)2012,JPO&INPIT |
