Description

This invention relates to a method and system for assisting with configuration changes. Conventionally, a proposed method is known that includes the steps of acquiring driving data when a vehicle is driven by a driver, and determining the driver's driving characteristics based on the driving data and proposing vehicle tuning suitable for the driver (see, for example, Patent Document 1). Japanese Patent Publication No. 2021-28795 This is a block diagram showing the schematic configuration of the setting change support system according to this embodiment.Figure 1 is a block diagram illustrating the in-vehicle device for the setting change support system.This is a flowchart illustrating the setting change support method using the setting change support system of this embodiment.This is a flowchart illustrating how to determine the content of the setting change in step S3 of Figure 3.Figure 1 shows an example of a radar chart displayed on the screen of the settings change support system. The following describes one embodiment of the present invention. First, the configuration of the setting change support system 100 according to one embodiment of the present invention will be described with reference to Figures 1, 2, and 5. The setting change support system 100 is used when personalizing the configurable vehicle 50 according to the driver. The setting change support system 100 is provided to make it easier to understand the direction of configuration changes for the vehicle 50, which may differ depending on the driver. Examples of configurable settings for the vehicle 50 include accelerator response, steering assist, and front/rear wheel torque distribution. The configuration change support system 100, as shown in Figure 1, comprises an in-vehicle device 1, a server device 2, and a personal computer (hereinafter referred to as "PC") 3. The in-vehicle device 1 and the server device 2 are connected via a network 150, and the server device 2 and the PC 3 are also connected via the network 150. Note that PC 3 is an example of the "computer" of the present invention. [In-vehicle device] The on-board device 1 is mounted on the vehicle 50 and is configured to acquire driving data when the vehicle 50 is driven by a driver. This acquisition of driving data is performed, for example, when the driver drives a predetermined course. Examples of predetermined courses include braking (sudden stopping at a target position after acceleration), slalom, and steady-state circular turns. As shown in Figure 2, the on-board device 1 includes an acquisition terminal 11, a GPS (Global Positioning System) receiver 12, and a communication device 13. The acquisition terminal 11 is connected to the vehicle's on-board network 51. Here, the vehicle's onboard network 51 includes a gateway ECU (hereinafter referred to as "GW-ECU") 52 and a plurality of buses 53 connected to the GW-ECU 52. Multiple ECUs 54 are connected to each bus 53. The ECUs 54 are configured to control various parts of the vehicle 50. The buses 53 are transmission paths for communication between the ECUs 54, and a communication protocol such as CAN (Controller Area Network) is used. The GW-ECU 52 is provided to relay communication between the plurality of buses 53. When ECU 54 sends a message to bus 53, other ECUs 54 connected to that bus 53 receive the message, and the GW-ECU 52 forwards the message to other buses 53, where ECUs 54 connected to those other buses 53 receive the message. In other words, in the in-vehicle network 51, messages are relayed by the GW-ECU 52, enabling communication between ECUs 54 connected to different buses 53. The ECU 54 is configured to transmit information about the vehicle 50 as a message to the bus 53. This information includes vehicle behavior information and vehicle operation information. For example, vehicle information may include vehicle speed, longitudinal acceleration, lateral acceleration, roll angle, pitch angle, yaw angle, accelerator input, brake input, steering input, and shift operation. The acquisition terminal 11 includes a microcontroller 11a that controls the acquisition terminal 11, a transceiver 11b connected to the microcontroller 11a, and an input/output unit 11c. The bus 53 of the in-vehicle network 51 is connected to the transceiver 11b, and the GPS receiver 12 and communication device 13 are connected to the input/output unit 11c. The microcontroller 11a is configured to acquire information about the vehicle 50 via the transceiver 11b when information about the vehicle 50 is transmitted from the ECU 54 to the bus 53. The GPS receiver 12 is configured to receive signals from GPS satellites (not shown) and calculate location information. The GPS receiver 12 also has a function to calculate the time of reception of signals from GPS satellites. Furthermore, the GPS receiver 12 is configured to output location information and reception time (hereinafter also referred to as "GPS information") to the acquisition terminal 1
