<P>PROBLEM TO BE SOLVED: To provide a drive control device for a vehicle equipped with a small-sized hydraulic pump driven by a drive source, capable of suppressing the energy output as much as practicable. <P>SOLUTION: The drive control device for vehicle is equipped with a total discharge amount computing means 96 to compute the total discharge amount Q<SB>ALL</SB>of a working oil required, an excess/shortage computing means 98 to compute the excess/shortage amount Q<SB>LA</SB>of the working oil with respect to the total discharge amount Q<SB>ALL</SB>, a first hydraulic pump output increasing amount computing means 100 to compute the first energy output increasing amount Δpow<SB>P1</SB>required of the first hydraulic pump 56 for discharging the working oil in the amount Q<SB>LA</SB>, a second hydraulic pump output increasing amount computing means 102 to compute the second energy output increasing amount Δpow<SB>P2</SB>required of the second hydraulic pump 58, and a hydraulic pump drive control means 104 which compares the first energy output increasing amount Δpow<SB>P1</SB>with the second energy output increasing amount Δpow<SB>P2</SB>and takes the smaller one for supplying the working oil in the amount Q<SB>LA</SB>, and thereby the energy output can be suppressed as much as practicable. <P>COPYRIGHT: (C)2004,JPO |
