摘要： When the total value of demanded hydraulic power and demanded traveling power is larger than the sum of the engine power that can be output by an engine (1) and of the discharge power that can be discharged by an electrical storage device (3), the actual power of a hydraulic pump (9) is increased from the value at the time of demand toward the demanded hydraulic power under the constraint of a predetermined limit. While the power of the hydraulic pump is being subjected to the predetermined limit, the actual power of the traveling motor is decreased from the value at the time of demand by a value smaller than the magnitude of the predetermined limit. This prevents worsening of ride comfort attributable to the distribution of power between the hydraulic pump and the traveling motor.
