PROBLEM TO BE SOLVED: To provide a vehicle drive control device that can reduce uncomfortable feeling caused by a change in a driving force in continuous shift-down transmission in vehicle acceleration in a vehicle an engine having a supercharger and an automatic transmission.SOLUTION: When continuous shift-down of an automatic transmission 12 is executed in vehicle acceleration, when a supercharging pressure Pcm is lower than a target supercharging pressure Pcmtgt in the first gear shift start, and the supercharging pressure is higher than the target supercharging pressure Pcmtgt in the second gear shift start, a supercharging pressure reduction gradient change control means 110 makes a reduction gradient &Dgr;Pcm of the supercharging pressure Pcm smaller as a reduction ratio &Dgr;PAP of acceleration opening degree PAP from the first gear shift start to the second gear shift start is smaller. Accordingly, in the continuous shift-down transmission in the vehicle acceleration, a temporary decrease in a driving force Fc can be suppressed by a change in the supercharging pressure against a driver's intention of acceleration, so uncomfortable feeling caused by the change in the driving force Fc can be reduced. |
