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 travel control plan generation device. The travel control plan generation device of patent document 1 is a vehicle control device capable of generating a travel control plan (hereinafter, also referred to as "travel plan") that reflects the driving preference of the driver and automatically travels the vehicle. Specifically, the travel control plan generation device receives, at a priority input unit, a priority for each driving preference of the driver, and sets, at a parameter value setting unit, a value of a travel control plan generation parameter according to the input priority. Then, the travel control plan generation device generates a travel plan in a plan generation unit using a travel control plan generation parameter that reflects the driving preference of the driver. Prior art literature Patent literature Patent document 1 Japanese patent application No. 4952268 The travel control plan generation device of patent document 1 generates the travel plan as described above, but if the amount of information required for the generation of the travel plan is small, the travel plan can be generated by the control device of the vehicle, and the use of calculation resources outside the vehicle is unnecessary. However, in electric vehicles and the like that have recently accelerated into the market, the demand for long-term travel plans is increasing from the viewpoint of energy management. In the above case, since the travel plan is a long-term plan, a huge amount of calculation is required to generate the travel plan, and thus there is a trend to place the calculation resources for generating the travel plan outside the vehicle such as the cloud. With this, it is necessary to appropriately coordinate the function of generating and executing the travel plan with the function of a safety system or the like that takes priority over executing the travel plan. 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 executing a travel plan determined by an external computing device that is wirelessly communicably connected to a vehicle, and capable of appropriately coordinating individual control and the travel plan that are prioritized over the travel plan. In order to achieve the above object, a control device for a vehicle according to one aspect of the present disclosure controls a control object included in a vehicle based on a travel plan of the vehicle that is determined in advance and input, the control device for a vehicle including a determination portion that determines a command parameter for controlling the control object so that the control object operates in accordance with the travel plan, an individual control execution portion that executes individual control that determines a permission condition that permits the command parameter outside the travel plan, and a change portion that changes the command parameter so that the command parameter is permitted by the permission condition when the command parameter determined by the determination portion deviates from the permission condition. In this way, in the case where the instruction parameter determined to make the control object act in accordance with the travel plan is incompatible with the permission condition determined by the above-described individual control, the permission condition is prioritized. Thus, it is possible to execute a travel plan, and appropriately coordinate the above-described individual control and travel plan that is more prioritized than the travel plan. In each column of the application document, each element may be given a bracketed reference numeral. In this case, the reference numerals denote only one example of the correspondence between the elements and the specific structure described in the embodiment described later. Thus, the present disclosure is not limited in any way by the recitation of the above-described reference numerals. Drawings Fig. 1 is a diagram schematically showing a vehicle of a first embodiment.
