AUTOMATIC DRIVING SYSTEM FOR VEHICLE
First Claim
1. An automatic driving system for a vehicle, comprising:
- an external sensor that detects vehicle peripheral information; and
an electronic control unit configured to generate a vehicle travel plan along a preset target route on a basis of map information and the vehicle peripheral information detected by the external sensor, the electronic control unit being configured to control automatic driving of the vehicle on a basis of the vehicle travel plan, the electronic control unit being configured to estimate whether the vehicle peripheral information detected by the external sensor allows the vehicle to keep a vehicle target speed set on a basis of the vehicle travel plan or temporarily does not allow the vehicle to keep the vehicle target speed, the electronic control unit being configured to, when it is estimated that the vehicle peripheral information temporarily does not allow the vehicle to keep the vehicle target speed, generate a plurality of vehicle travel plans during a travel duration for which it is estimated that the vehicle peripheral information temporarily does not allow the vehicle to keep the vehicle target speed, and select one of the plurality of vehicle travel plans, which provides a lowest fuel consumption of an engine, the electronic control unit being configured to, during the travel duration for which it is estimated that the vehicle peripheral information temporarily does not allow the vehicle to keep the vehicle target speed, control driving of the engine and driving of a steering apparatus in accordance with the selected one of the vehicle travel plans.

Abstract
An automatic driving system for a vehicle includes an external sensor and an electronic control unit. The electronic control unit is configured to estimate whether the vehicle peripheral information detected by the external sensor allows the vehicle to keep a vehicle target speed set on the basis of a vehicle travel plan or temporarily does not allow the vehicle to keep the vehicle target speed. The electronic control unit is configured to, when it is estimated that the vehicle peripheral information temporarily does not allow the vehicle to keep the vehicle target speed, generate a plurality of vehicle travel plans during a travel duration for which it is estimated that the vehicle peripheral information temporarily does not allow the vehicle to keep the vehicle target speed, and select one of the plurality of vehicle travel plans, which provides a lowest fuel consumption of an engine.
