Driving control device, driving control system, and driving control method

Abstract

The present invention provides a travel control device, a travel control system, and a travel control method capable of changing a travel control method according to communication capacity. The travel control device includes: a travel control unit that executes the travel control of the vehicle; an information adding unit that acquires additional information added to the map information through communication with the outside, and adds the acquired additional information to the map information; a required capacity acquisition unit, A necessary capacity which is a communication capacity required to acquire the additional information is acquired; and a remaining capacity acquisition unit acquires a remaining capacity of the communication capacity calculated based on a preset limit value of the communication capacity. The travel control unit can perform travel control in a plurality of methods including at least the first method and the second method, and execute travel control in any one method based on the required capacity and the remaining capacity. The first method is a method of driving control performed based on map information and is a method of driving control of a vehicle in which the required capacity of additional information is larger than that of the second method.

Description

technical field [0001] The present disclosure relates to a travel control device, a travel control system, and a travel control method. Background technique [0002] There is known a device having a function of acquiring additional information added to map information by communicating with the outside, and adding the acquired additional information to the map information. For example, Patent Document 1 describes a navigation device having such a function. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-233897 [0004] However, when the driving control is performed in a vehicle with a high level of driving assistance, detailed and new map information is required, so additional information is obtained through communication with the outside while the driving control is being performed. Here, generally, when communicating with the outside, the limit value of the communication capacity is set according to the communication cost borne by the user in advance. Ther...

Problems solved by technology

Therefore, if the driving control in the mode with a high driving assistance level is continued regardless of the communication capacity, the user may have to purchase additional communication capacity when the communication capacity reaches the limit value.
