First Claim
Patent Images
1. A vehicle travel controller for a vehicle, comprising:
- a road branching detector configured to detect a branching of a road ahead of the vehicle;
a setting device configured to set a target vehicle speed with respect to the road ahead of the vehicle; and
a speed control part configured to, when the road branching detector detects branching of the road ahead of the vehicle, perform primary speed reduction control for a first deceleration and perform secondary speed reduction control for a second deceleration after the primary speed reduction control, the second deceleration higher than the first deceleration with respect to a road with a lowest target vehicle speed among plural roads at the branching.

Abstract
A vehicle travel controller for a vehicle comprises a road branching detector configured to detect a branching of a road ahead of the vehicle and a setting device configured to set a target vehicle speed with respect to the road ahead of the vehicle. When road branching is detected ahead of the vehicle, after a primary speed reduction control for a first deceleration a secondary speed reduction control is performed for a second deceleration higher than the first deceleration with respect to the road with a lowest target vehicle speed among various roads at the branching.

13. A vehicle travel controller for a vehicle, comprising:
-
means for detecting a branching of a road ahead of the vehicle; means for setting a target vehicle speed with respect to the road ahead of the vehicle; and means for performing primary speed reduction control for a first deceleration when the road branching detector detects branching of the road ahead of the vehicle and for performing secondary speed reduction control for a second deceleration after the primary speed reduction control, the second deceleration higher than the first deceleration with respect to a road with a lowest target vehicle speed among plural roads at the branching.

14. A method for vehicle traveling control of a vehicle, the method comprising.
detecting a presence or absence of branching on a road ahead of the vehicle; -
performing primary speed reduction control at a first deceleration when the branching is detected; and performing secondary speed reduction control for a second deceleration after the primary speed reduction control, the second deceleration higher than the first deceleration with respect to a road with a lowest target vehicle speed among plural roads at the branching. - View Dependent Claims (15, 16, 17, 18, 19, 20)
