Abstract
A travel control device repeats a burn control that accelerates a vehicle at a target acceleration until speed of the vehicle reaches an upper limit speed of a vehicle speed range and a coasting control that makes the vehicle travel by means of inertia until the speed of the vehicle reaches a lower limit speed of the vehicle speed range. Further, a vehicle speed width that is a width of the vehicle speed range and the target acceleration are changed based on calculated travel resistance.
Claims15
A travel control device for controlling travel of a vehicle provided with an internal combustion engine, the travel control device comprising:
- a calculation unit that calculates a travel resistance of the vehicle;
- and
- a speed control unit that controls a speed of the vehicle,
- wherein:
- the speed control unit is configured to execute a burn-and-coast control that repeatedly executes a burn control which accelerates the vehicle by means of driving force of the internal combustion engine and a coasting control which stops generation of the driving force of the internal combustion engine so that the vehicle travels by means of inertia;
- the burn control is configured to accelerate the vehicle at a predetermined acceleration until the speed of the vehicle reaches an upper limit of a predetermined vehicle speed range;
- the coasting control is configured to make the vehicle travel by the inertia until the speed of the vehicle reaches a lower limit of the vehicle speed range;
- and
- a vehicle speed width that is a width of the vehicle speed range and the acceleration are changed based on the calculated travel resistance.
