Abstract

[Problem] By periodically receiving vehicle data from the ECU or VCU and storing the time-series data, it is possible to request the calculation software to calculate battery consumption using the predicted data, even if communication with the ECU or VCU is interrupted. [Solution] The intermediary application comprises a first communication unit that receives a first calculation request from the navigation application, a second communication unit that periodically receives vehicle data, including at least the vehicle's battery level, from the ECU or VCU installed in the vehicle, a storage unit that stores time-series data of the received vehicle data, and a third communication unit that sends a second calculation request including prediction data to calculation software that calculates a predicted value of the battery level at the time of arrival at the destination, and receives the battery consumption calculation result from the calculation software, and the first communication unit transmits the calculation result to the navigation application.

Description

This invention relates to an intermediary device, an intermediary method, and an intermediary program. In the field of electric vehicle technology, attempts are being made to select the most energy-efficient driving route by calculating the battery consumption of the vehicle, with the aim of increasing driving range and reducing energy consumption. Patent Document 1 discloses a route selection system for electric trucks that can further improve energy efficiency. This route selection system includes a map information acquisition means, a transport weight information acquisition means, a fluctuation information estimation means, and an optimal route selection means. The map information acquisition means acquires map information including the electric truck's transport start point information and transport route information from the transport start point to the cargo loading/unloading point. The transport weight information acquisition means acquires transport weight information including the initial weight information of the initial load loaded at the transport start point and the loading/unloading weight information of the cargo loaded and unloaded at the cargo loading/unloading point. The fluctuation information acquisition means estimates fluctuation information of the total load that changes during transport based on the transport weight information. The optimal route selection means selects the optimal route based on basic information including map information and fluctuation information. Patent Document 2 discloses an information-providing device that can provide useful information regarding the driving range, taking into account the characteristic that fuel efficiency changes significantly depending on the route. This information-providing device sets multiple provisional destinations in dispersed directions based on the electric vehicle's current location and searches for each route to each of these provisional destinations. Furthermore, this information-providing device calculates the driving distance possible with the current battery level when traveling along each of the searched routes and provides information based on the calculated distances. In this way, the information-providing device, rather than providing information indicating the driving range for a specific single route when no guided route to a destination has been set, provides information that takes into account the multiple driving ranges calculated for multiple dispersed routes. Patent Document 3 discloses an information processing device that can contribute to promoting the switch of internal combustion engine vehicle users to battery electric vehicles (BEVs). In this information processing device, a control unit acquires the operation history of an internal combustion engine vehicle over a first period. The control unit determines whether battery charging will be necessary during the operation of the first BEV, assuming that the BEV is operated according to the operation schedule indicated by the acquired operation history. If it is determined that battery charging will be necessary during the operation of the first BEV, the control unit generates first information including information regarding charging timing and charging location, and outputs the generated first information through a first terminal.
