Vehicle travel control system
First Claim
1. A vehicle travel control system for controlling travel of a vehicle based on a travel plan, comprising:
- a controller including circuitry,wherein the circuitry includes;
initial travel plan producing circuitry configured to produce an initial travel plan including a decelerating interval in which an internal combustion engine is stopped to decelerate the vehicle; and
first replanning circuitry configured to replan the initial travel plan so that target deceleration in the decelerating interval is set larger than that in the initial travel plan when a non-stop state of the internal combustion engine occurs while the vehicle is traveling.

Abstract
An ECU that integrally controls a vehicle travel control system includes an initial travel plan producing section which produces an initial travel plan including a decelerating interval in which an engine of a vehicle is stopped to decelerate the vehicle, a travel plan reconfiguring section which reconfigures the initial travel plan produced by the initial travel plan reconfiguring section, and a travel control section which controls travel of the vehicle based on a travel plan. When a non-stop state of the engine occurs while the vehicle is traveling, the travel plan reconfiguring section reconfigures the initial travel plan so that target deceleration in the decelerating interval in the initial travel plan is reset to new target deceleration that is larger deceleration.

8. A vehicle travel control system for controlling travel of a vehicle based on a travel plan, comprising:
-
a controller including circuitry, wherein the circuitry includes; initial travel plan producing circuitry configured to estimate fuel consumption of the vehicle and produce an initial travel plan in consideration of a fuel consumption characteristic; actual fuel consumption computing circuitry configured to compute an actual fuel consumption of the vehicle which travels based on the initial travel plan; and travel plan reconfiguring circuitry configured to reconfigure the initial travel plan so that an expected fuel consumption becomes less than the initial travel plan if the actual fuel consumption exceeds the expected fuel consumption of the initial travel plan.

9. An ECU-implemented vehicle travel control method for controlling travel of a vehicle based on a travel plan, comprising:
-
producing, via the ECU, an initial travel plan including a decelerating interval in which an internal combustion engine is stopped to decelerate the vehicle; and replanning, via the ECU, the initial travel plan so that target deceleration in the decelerating interval is set larger than that in the initial travel plan when a non-stop state of the internal combustion engine occurs while the vehicle is traveling. - View Dependent Claims (10, 11)
