Abstract

Disclosed is a driving torque control device for a vehicle comprising the elements. The device can effectively suppress fluctuation of engine torque. (1) Means for calculating a torque control timing to determine and output at least two control timings of an engine torque generated by an engine during speed shifting. (2) Means for calculating and outputting an engine torque control quantity in response to the output from said torque control timing calculating means to calculate and output the engine torque control quantity (3) Means for controlling the engine torque during speed shifting in response to the outputs from said engine torque control quantity calculating means. The engine torque is reduced by a certain quantity at a first timing of said engine torque control timings, followed by increasing the engine torque at the second engine torque control timing, and then returning the engine torque to the engine torque of the time immediately before the first engine torque control timing.
