Description

Vehicle control device Technical Field The present invention relates to the technical field of vehicle control devices. Background As such a device, for example, there is proposed a device that records travel log data in a period from when a vehicle starts traveling to when the traveling is completed, and that performs a process of increasing the free capacity of a storage device when it is predicted that the capacity of the storage device that records the travel log data is insufficient (refer to patent document 1). Patent document 1 Japanese patent application laid-open No. 2024-055485 Disclosure of Invention The technique described in patent document 1 has room for improvement. The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle control device capable of appropriately recording travel log data. A vehicle control device according to an aspect of the present invention includes a storage device for recording travel log data of a vehicle, and an adjustment mechanism for performing an adjustment process for adjusting a travel plan or travel log data of the vehicle when it is predicted that the capacity of the storage device is insufficient. Drawings Fig. 1 is a block diagram showing an example of a configuration of a vehicle according to an embodiment. Detailed Description An embodiment of a vehicle control device will be described with reference to fig. 1. In fig. 1, a vehicle control device 10 is mounted on a vehicle 1. The vehicle control device 10 includes an automatic driving control device 11 and a journal management device 12. The automatic driving control device 11 is a device for realizing automatic driving of the vehicle 1. The automatic driving control device 11 executes processing relating to automatic driving based on information or the like detected by each of a plurality of sensors provided in the vehicle 1. Examples of the plurality of sensors included in the vehicle 1 include a sensor that detects the surrounding environment of the vehicle 1, such as a camera, millimeter wave radar, light Detection, ranging, laser imaging Detection, and ranging (Light Detection AND RANGING/LASER IMAGING Detection AND RANGING: liDAR), a vehicle speed sensor, an acceleration sensor, and a gyro sensor, and a sensor that detects the running state of the vehicle 1. The sensor included in the vehicle 1 includes a global positioning system (Global Positioning System: GPS) receiver as a position sensor. The vehicle 1 may be configured to be able to communicate with an external device via the internet. That is, the vehicle 1 may be a networked automobile. In this case, the automatic driving control device 11 may execute processing relating to automatic driving based on information or the like acquired from a server on the internet, other than information detected by each of the plurality of sensors provided in the vehicle 1. For example, the log management device 12 manages travel log data from the time when the vehicle 1 starts traveling to the time when the vehicle 1 ends traveling. For example, the travel log data includes time-series data of detection information of each of a plurality of sensors included in the vehicle 1 and time-series data of control information of the automatic driving control device 11. The time-series data of the detection information includes time-series data of at least one of a travel image, point group data, a vehicle distance, a white line recognition state, a detected object, a vehicle speed, an acceleration, a yaw rate, and GPS position information. The time-series data of the control information includes at least one of a throttle opening command value, a brake control amount, a steering control amount, a target travel locus, and a self-position estimation result. The log management device 12 may also acquire a travel plan associated with the vehicle 1. The travel plan is information that specifies travel of the vehicle 1 to the destination. For example, the travel plan may include at least one of position information of a destination, a travel route to the destination, and arrival time of the destination. The log management device 12 includes a processing unit 121 and a storage device 122. For example, the processing section 121 may include a processor and a memory. For example, the storage 122 may include at least one of a hard disk drive (HARD DISK DRIVE: HDD) and a Solid state drive (Solid STATE DRIVE: SSD). The travel log data is recorded in the storage device 122. For example, the travel log data of the vehicle 1 is recorded in the storage device 122 for the purpose of finding the cause of an accident or a failure. In particular, in an autonomous vehicle, since a system is large compared with a general vehicle and attribution capable of objectively and clearly defining responsibility is required, it is desired that recorded travel log data is large. For this purpose, it is desirable that the travel log data recor
