<P>PROBLEM TO BE SOLVED: To reduce a burden for a driver required for travel, to make driving feeling for the driver comfortable, and to enhance energy efficiency for a vehicle. <P>SOLUTION: A target acceleration G* is set in response to a vehicular speed V to generate a slight acceleration in a low vehicular speed area, to travel at constant speed in a middle vehicular speed area, and to bring a deceleration in a high speed area (S490), when a prescribed time lapses after acceleration-off and braking-off (S460), and when an acceleration G of the vehicle comes to a determination value Gref or less corresponding to the vehicular speed V and a road face slope θ even before this (S480), and an engine or a motor is controlled to bring an acceleration G of the vehicle into the target acceleration G*. The burden for the driver required for the travel is thereby reduced, and the driving feeling for the driver is made comfortable. The energy efficiency for the vehicle is also enhanced because the engine is operated efficiently in response to requirement. <P>COPYRIGHT: (C)2007,JPO&INPIT |
