no. 1 Embodiment approach ＞

[0031] exist figure 1 The configurations of the drive system and the control device of the vehicle VC1 according to the present embodiment are shown in .

[0032] like figure 1 As shown, in the intake passage 12 of the internal combustion engine 10, a throttle valve 14 and a fuel injection valve 16 are arranged sequentially from the upstream side, and the air sucked into the intake passage 12 and the fuel injected from the fuel injection valve 16 are accompanied by the intake air. When the valve 18 is opened, the fuel flows into the combustion chamber 24 defined by the cylinder 20 and the piston 22 . In the combustion chamber 24 , a mixture of fuel and air is provided for combustion with spark discharge from an ignition device 26 , and energy generated by the combustion is converted into rotational energy of a crankshaft 28 via a piston 22 . The air-fuel mixture supplied for combustion is discharged as exhaust gas to the exhaust passage 32 with the opening of the exhaust val...

no. 2 Embodiment approach ＞

[0087] Hereinafter, the second embodiment will be described focusing on differences from the first embodiment with reference to the drawings.

[0088] exist Figure 7 The drive system and control device of the vehicle VC1 according to this embodiment are shown in . In addition, in Figure 7 In, for the convenience of explanation, for the figure 1 Corresponding parts to those shown are given the same reference numerals.

[0089] like Figure 7 As shown, in this embodiment, a learning program 74b is stored in the ROM 74 in addition to the control program 74a. In addition, map data DM is not stored in the storage device 76, but relationship specification data DR is stored instead, and torque output map data DT is stored. Here, the relationship specifies that the data DR is passed through Figure 4 The learned data is the time-series data of the accelerator operation amount PA, the vehicle speed V, and the gear ratio GR for the state s, and the throttle opening degree comman...

no. 3 Embodiment approach ＞

[0094] Hereinafter, the third embodiment will be described focusing on differences from the second embodiment with reference to the drawings.

[0095] In the present embodiment, the update of the relationship defining data DR is performed outside the vehicle VC1.

[0096] exist Figure 9 In the figure, the structure of the control system which performs reinforcement learning in this embodiment is shown. In addition, in Figure 9 In, for the convenience of explanation, for the figure 1 Corresponding parts to those shown are given the same reference numerals.

[0097] Figure 9 The ROM 74 in the control device 70 in the illustrated vehicle VC1 stores a control program 74a, but does not store a learning program 74b. In addition, the control device 70 includes a communication device 77 . The communicator 77 is a device for communicating with the data analysis center 130 via the network 120 outside the vehicle VC1 .

[0098] The data analysis center 130 analyzes data transmi...

Abstract

The invention provides a method for generating vehicle controlling data, a vehicle controller, a vehicle control system, and a learning device for a vehicle. The method for generating vehicle controlling data includes executing an operating process that operates an electronic device, executing an obtaining process that obtains a state of a vehicle, executing a reward calculation process that assigns a reward based on the state of the vehicle, and an updating process that updates relationship specifying data. The reward calculation process includes a changing process that changes a reward assigned when an area variable equals a second value and a property of the vehicle is a predetermined property from a reward assigned when the area variable equals a first value and the property of the vehicle is the predetermined property.

Description

technical field [0001] The present disclosure relates to a method of generating control data for a vehicle, a control device for a vehicle, a control system for a vehicle, and a learning device for a vehicle. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 2016-6327 describes a control device that operates a throttle valve that is an operating unit of an internal combustion engine mounted on a vehicle based on a value obtained by processing an accelerator pedal operation amount with a filter. . [0003] The above-mentioned filter needs to set the operation amount of the throttle valve of the internal combustion engine mounted on the vehicle to an appropriate operation amount according to the operation amount of the accelerator pedal. Therefore, the adaptation of the filter requires many man-hours for those skilled in the art. In this way, conventionally, it took many man-hours for those skilled in the art to adjust the operation amount ...
