Description

Control device for vehicle Technical Field The present disclosure relates to a vehicle control device that automatically controls a control object of a vehicle. Background Patent document 1 discloses a navigation device. The navigation device of patent document 1 detects coordinates of a current position of a vehicle, calculates a straight line that passes through the detected coordinates of a destination and is orthogonal to the detected azimuth of the vehicle at the same point, and calculates a distance between the straight line and the coordinates of the current position of the vehicle as a distance from the destination. In patent document 1, for example, an automatic deceleration control for reducing the vehicle speed from just before the destination such as a toll gate can be appropriately performed. Prior art literature Patent literature Patent document 1 Japanese patent No. 3664219 For example, in order to extend the cruising distance of a vehicle while ensuring the comfort of a passenger, the necessity of a technique related to automatic control for adjusting the energy consumption of the vehicle has been increasing in recent years. However, patent document 1 is related to automatic control of a vehicle, but does not disclose a technique for adjusting energy consumption of the vehicle. As a result of the detailed study by the inventors, the above-described situation was found. Disclosure of Invention In view of the above, an object of the present disclosure is to provide a vehicle control device capable of appropriately adjusting the energy consumption of a vehicle in accordance with the traveling of the vehicle. In order to achieve the above object, one aspect of the present disclosure provides a control device for a vehicle, which automatically controls a predetermined physical quantity to be close to a control target value by operating a control object of a vehicle traveling on a predetermined travel route to adjust energy consumption of the vehicle, Further, the control device for a vehicle includes: A storage unit that stores in advance at least one route point located on the planned travel route and a route point correspondence target value corresponding to the route point; An arrival determination unit that determines whether or not the vehicle has arrived at least one of the route points, and And a target value determining unit configured to determine, as the control target value, the route point correspondence target value corresponding to at least one of the route points determined to be reached by the vehicle, when the arrival determining unit determines that the vehicle has reached at least one of the route points. In this way, since the above-described physical quantity is adjusted at least one route point on the planned travel route, the energy consumption of the vehicle can be appropriately adjusted in accordance with the traveling situation of the vehicle along the planned travel route. In summary, the energy consumption of the vehicle can be appropriately adjusted in accordance with the traveling of the vehicle. Thus, for example, both a safety of the passenger and a reduction of the energy consumption can be achieved.
