Abstract
Provided are a travel control device, a vehicle, and a travel control method that ensure safety in cases of a possible lane departure. This travel control device is equipped with: a travel control unit that switches between and executes a constant speed travel control for causing a vehicle 1 to travel at a target speed and a coasting control for causing the vehicle to travel by inertia; and a switching control unit that, in cases in which it has been determined by a lane departure warning unit that there is a risk that the vehicle will depart from the travel lane while executing the constant speed travel control or the coasting control, controls the travel control unit to execute the constant speed travel control without executing the coasting control for a prescribed period of time.
Claims11
A travel control device, comprising:
- a travel control circuitry that switches between a constant velocity traveling control for causing a vehicle to travel at a target vehicle velocity and a coasting control for allowing the vehicle to travel by inertia in a state where a clutch is disengaged and an engine is disconnected from wheels, switching from the constant velocity traveling control to the coasting control being performed when the velocity of vehicle is within a predetermined range, and
- a switching control circuitry that controls the travel control circuitry to execute continuing the constant velocity traveling control without executing the coasting control even when the velocity of vehicle is within the predetermined range, when the vehicle approaches within a predetermined distance to a boundary of a traveling lane under the constant velocity traveling control, and execute switching to the constant velocity traveling control without executing the coasting control even when the velocity of vehicle is within the predetermined range, when the vehicle approaches within the predetermined distance to the boundary of the traveling lane under the coasting control.
A vehicle, comprising:
- a travel control device comprises
- a travel control circuitry that switches between a constant velocity traveling control for causing a vehicle to travel at a target vehicle velocity and a coasting control for allowing the vehicle to travel by inertia in a state where a clutch is disengaged and an engine is disconnected from wheels, switching from the constant velocity traveling control to the coasting control being performed when the velocity of vehicle is within a predetermined range, and
- a switching control circuitry that controls the travel control circuitry to execute continuing the constant velocity traveling control without executing the coasting control even when the velocity of vehicle is within the predetermined range, when the vehicle approaches within a predetermined distance to a boundary of a traveling lane under the constant velocity traveling control, and execute switching to the constant velocity traveling control without executing the coasting control even when the velocity of vehicle is within the predetermined range, when the vehicle approaches within the predetermined distance to the boundary of the traveling lane under the coasting control.
A travel control method performed by a travel control device that switches between a constant velocity traveling control for causing a vehicle to travel at a target vehicle velocity and a coasting control for allowing the vehicle to travel by inertia in a state where a clutch is disengaged and an engine is disconnected from wheels, switching from the constant velocity traveling control to the coasting control being performed when the velocity of vehicle is within a predetermined range, the method comprising:
- executing continuing the constant velocity traveling control without executing the coasting control even when the velocity of vehicle is within the predetermined range, when the vehicle approaches within a predetermined distance to a boundary of the traveling lane under the constant velocity traveling control, and executing switching to the constant velocity traveling control without executing the coasting control even when the velocity of vehicle is within the predetermined range, when the vehicle approaches within the predetermined distance to the boundary of the traveling lane under the coasting control.
