摘要： PROBLEM TO BE SOLVED: To improve fuel economy by enhancing energy efficiency by using a hydraulic transmission method as a base.
SOLUTION: In a controller 15, a travelling acceleration is calculated from a detected vehicle speed, and it is determined, based on the travelling acceleration, whether it is travelling on a flat road where relatively small travelling energy is required or it is climbing up a slope where relatively large travelling energy is required. When it is travelling on the flat road, fuel consumption is suppressed by issuing an instruction for limiting a fuel injection quantity of an engine as a normal control to an engine control part 16. When it is climbing up, the travelling energy is secured by switching to a power control in which an engine speed is increased compared to travelling on the flat road.
