1. A vehicle travel control device, comprising:

  • a first controller that controls an engine driving force based on a driving target controlled variable;

    a second controller that controls a braking force of a brake device based on a braking target controlled variable; and

    a third controller that calculates the driving target controlled variable and/or braking target controlled variable for performing vehicle travel control so that a vehicle speed of a vehicle becomes a target vehicle speed, and outputs the driving target controlled variable to the first controller and the braking target controlled variable to the second controller,wherein the third controller is configured to calculate driving target vehicle speed for the vehicle travel control by the engine driving force and to calculate braking target vehicle speed for the vehicle travel control by the braking force of the braking device, andwherein upon detection of an acceleration operation performed by a driver during the vehicle travel control, the third controller sets the driving target controlled variable for the vehicle travel control in accordance with the engine driving force of the engine in response to the acceleration operation and the driving force that is calculated based on the driving target vehicle speed for the vehicle travel control, and sets the braking target vehicle speed for the vehicle travel control to a larger speed than the current vehicle speed.
