Travel control device and vehicle

A travel control device which controls at least acceleration/deceleration of a vehicle, the travel control device comprising:

• acceleration/deceleration characteristic setting means for setting the range of an accelerator operation amount or a brake operation amount corresponding to a target acceleration/deceleration greater than the range of an accelerator operation amount or a brake operation amount corresponding to an acceleration/deceleration other than the target acceleration/deceleration;
• steering characteristic setting means for setting the range of a steering operation amount corresponding to a target tire angle greater than the range of a steering operation amount corresponding to a tire angle other than the target tire angle,
• wherein, when the rear portion of the vehicle skids, the steering characteristic setting means sets the range of the steering operation amount corresponding to the target tire angle for suppressing or/and maintaining skidding greater, and
• when the rear portion of the vehicle skids, the acceleration/deceleration characteristic setting means sets the range of the accelerator operation amount or the brake operation amount corresponding to the target acceleration/deceleration for maintaining skidding greater.

A travel control device which controls at least acceleration/deceleration of a vehicle, the travel control device comprising:

• a control unit programmed to set the range of an accelerator operation amount or a brake operation amount corresponding to a target acceleration/deceleration greater than the range of an accelerator operation amount or a brake operation amount corresponding to an acceleration/deceleration other than the target acceleration/deceleration;
• and
• a basic map which defines the relationship between the accelerator operation amount and the acceleration/deceleration corresponding to the accelerator operation amount and the relationship between the brake operation amount and the acceleration/deceleration corresponding to the brake operation amount,
• wherein the control unit sets the range of the accelerator operation amount or the brake operation amount corresponding to the acceleration/deceleration for achieving the target acceleration/deceleration greater than the basic map and generates an acceleration/deceleration characteristic map which intersects the basic map at least at a maximum deceleration to a maximum brake operation point.
