[0010] Some exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Note that the following description illustrates one specific example of the present disclosure and should not be construed as limiting the present disclosure. For example, each element, including numerical values, shapes, materials, parts, the position of each part, and the connection method of each part, is merely an example and should not be construed as limiting the present disclosure. Furthermore, in the following exemplary embodiments, components not described in independent claims based on the highest concept of the present disclosure are optional and may be provided as needed. The drawings are schematic and are not intended to be drawn to scale. Throughout this specification and the drawings, components having substantially the same function and configuration are designated by the same reference numerals, and redundant description will be omitted. Furthermore, components not directly related to one embodiment of the present disclosure are not shown in the drawings.

[0011] <1. Background> Vehicle parts or software may be replaced with more effective parts or software. Patent Document 1 discloses a method for presenting the effects on vehicle performance resulting from replacing the parts or software with more effective parts or software. However, the invention described in Patent Document 1 does not indicate the necessity of replacing the parts or software with more effective parts or software, making it difficult for the driver to understand the need for the replacement with the proposed parts or software. As a result, the driver may not replace the parts or software with the proposed parts or software. Therefore, after extensive research, the inventors of the present application have conceived a technology that can help the driver understand the need for replacing the parts or software with new parts or software and effectively encourage them to replace the parts or software with new parts or software. The proposed device, vehicle, and server device for realizing this technology are described in detail below.

[0012] <2. Embodiment> [Configuration example] First, a vehicle 1 equipped with an exchange proposal unit 31 according to a first embodiment of the present disclosure will be described. The exchange proposal unit 31 corresponds to a specific example of a "proposal device" of the present disclosure.

[0013] Vehicle 1 is capable of traveling by being driven by a prime mover 70 (engine or motor). Vehicle 1 includes, for example, a sensor unit 10, a communication unit 20, a control unit 30, memory units 40 and 50, a display unit 60, prime mover 70, a brake 80, and an EPS (Electric Power Steering) motor 90, as shown in FIG.

[0014] The sensor unit 10 is configured to include various sensors mounted on the vehicle 1. The sensor unit 10 is configured to include, for example, an accelerator opening sensor, a vehicle speed sensor, an acceleration sensor, an angular velocity sensor, a steering angle sensor, a steering torque sensor, and a brake torque sensor. The sensor unit 10 may include sensors other than those described above.

[0015] The accelerator opening sensor is capable of detecting the accelerator opening from the amount of depression of the accelerator pedal. The accelerator opening sensor is capable of outputting time-series data (accelerator opening data) regarding the detected accelerator opening to the control unit 30.

[0016] The vehicle speed sensor is capable of detecting the speed (vehicle speed) of the vehicle 1. The vehicle speed sensor is capable of outputting time series data (vehicle speed data) about the detected vehicle speed to the control unit 30. The acceleration sensor is capable of detecting acceleration applied to the vehicle 1. The acceleration sensor is capable of outputting time series data (acceleration data) about the detected acceleration in three directions to the control unit 30. The angular velocity sensor is capable of detecting the angular velocity of the vehicle 1. The angular velocity sensor is capable of outputting time series data (angular velocity data) about the detected three angular velocities (yaw angular velocity, roll angular velocity, pitch angular velocity) to the control unit 30.

[0017] The steering angle sensor is capable of detecting the steering angle of the steering wheel of the vehicle 1 (steering angle). The steering angle sensor is capable of outputting time-series data (steering angle data) about the detected steering angle to the control unit 30. The steering torque sensor is capable of detecting the steering torque generated by the driver's steering wheel operation. The steering torque sensor is capable of outputting time-series data (steering torque data) about the detected steering torque to the control unit 30. The brake torque sensor is capable of detecting the braking force (torque of the brake 70) relative to the brake pressure of the vehicle 1. The brake torque sensor is capable of outputting time-series data (braking force data) about the detected braking force to the control unit 30.

[0018] The sensor unit 10 further includes a stereo camera mounted on the vehicle 1 and a driving environment detection unit. The stereo camera is an autonomous sensor that senses the real space around the vehicle 1. The stereo cameras are, for example, arranged at symmetrical positions on either side of the central part in the width direction of the vehicle 1, and are capable of capturing stereo images of the area in front of the vehicle 1 from different viewpoints. The stereo cameras are capable of outputting image data Da (a pair of stereo image data) obtained by capturing images to the control unit 30.

[0019] The stereo camera is capable of generating distance image data Db calculated from the amount of displacement between corresponding objects based on image data Da (a pair of stereo image data) obtained by capturing images. The driving environment detection unit is capable of, for example, calculating lane markings that divide the road around the vehicle 1 based on the distance image data Db. The driving environment detection unit is also capable of calculating the road curvature of the markings that divide the left and right sides of the road (driving lane) on which the vehicle 1 is traveling, and the width between the left and right markings (vehicle width). The driving environment detection unit is also capable of performing predetermined pattern matching on the distance image data Db to detect lanes and three-dimensional objects such as structures present around the vehicle 1.

[0020] Here, when detecting a three-dimensional object in the driving environment detection unit, for example, the type of the three-dimensional object, the distance to the three-dimensional object, the speed of the three-dimensional object, and the relative speed between the three-dimensional object and the vehicle (host vehicle) are detected. Examples of three-dimensional objects to be detected include traffic lights, intersections, road signs, stop lines, other vehicles, pedestrians, bicycles, and buildings. Examples of buildings include detached houses, apartment complexes (condominiums), commercial facilities, factories, and signs. The driving environment detection unit is capable of outputting driving environment information around the vehicle 1, including the thus acquired information on the three-dimensional object, to the control unit 30.

[0021] The communication unit 20 can acquire data to supplement data that cannot be obtained from the image data Da and the distance image data Db, for example, through vehicle-to-vehicle communication, road-to-vehicle communication, and satellite communication. The communication unit 20 can output the acquired data to the control unit 30.

[0022] The communication unit 20 is capable of acquiring data (e.g., vehicle position, vehicle speed) obtained by other vehicles, for example, through vehicle-to-vehicle communication. The communication unit 20 is capable of receiving positioning signals transmitted from multiple positioning satellites, for example, through satellite communication.

[0023] The communication unit 20 is capable of acquiring road map data of the surroundings of the vehicle 1, for example, through road-to-vehicle communication. The road map data consists of, for example, highly accurate road map information (dynamic map), and has static information and quasi-static information that mainly constitute road information, and quasi-dynamic information and dynamic information that mainly constitute traffic information.

[0024] Static information that makes up road information includes information that needs to be updated within one month, such as roads, structures on roads, structures around roads, lane information, road surface information, and permanent traffic regulations. "Roads" include, for example, road locations and shapes, intersections, and road attributes (e.g., national roads, prefectural roads, city roads, private roads, priority roads, non-priority roads, general roads, and expressways). "Structures on roads" include, for example, traffic signs, traffic lights, convex mirrors, footbridges, bus stops, and garbage collection stations. "Structures around roads" include, for example, various buildings and parks.

[0025] The quasi-static information that constitutes road information is composed of information that needs to be updated every hour or less, such as traffic regulation information due to road construction or events, wide-area weather information, and traffic congestion forecasts.

[0026] The semi-dynamic information that makes up traffic information is composed of information that must be updated within one minute, such as the actual traffic congestion situation at the time of observation, driving restrictions, temporary driving obstructions such as fallen objects and obstacles, actual accident conditions, and narrow-area weather information.

[0027] The dynamic information that constitutes the traffic information is composed of information that needs to be updated every second, such as information sent and exchanged between moving bodies, information on currently displayed traffic signals, information on pedestrians and bicycles at intersections, information on vehicles traveling on roads, etc. Such road map information is maintained and updated periodically until the next information is received from each vehicle, and the updated road map information is transmitted to each vehicle as appropriate via the communication unit 20.

[0028] The communication unit 20 is capable of communicating with the terminal device 100, for example, via a predetermined communication network. The terminal device 100 is, for example, a terminal device owned by the driver of the vehicle 1, and is capable of receiving data (for example, emails, message data of SNS, etc.) transmitted from the control unit 30 via the communication unit 20 and displaying the data on a display screen.

[0029] The control unit 30 is capable of controlling the entire vehicle 1. The control unit 30 is, for example, a so-called ECU (Electronic Control Unit) and is configured to include, for example, one or more processors and one or more memories. The control unit 30 may be configured to include, for example, a CPU (Central Processing Unit). In this case, the control unit 30 is capable of controlling the entire vehicle 1 by, for example, executing a program stored in a storage unit.

[0030] The control unit 30 includes, for example, a locator unit. The locator unit is capable of acquiring the position coordinates of the vehicle 1 based on the positioning signal received through the communication unit 20. The locator unit is capable of estimating the vehicle's position on a road map by map-matching the acquired position coordinates with route map information. Based on the acquired position coordinates of the vehicle 1, the locator unit acquires map information of a predetermined range including the vehicle 1 from map information stored in a road map DB (database) 41 (described later).

[0031] In an environment where it is not possible to receive valid positioning signals from positioning satellites due to reduced sensitivity, such as when driving inside a tunnel, the locator unit can switch to autonomous navigation, which estimates the vehicle's position based on the vehicle speed, angular velocity, and longitudinal acceleration detected by sensor unit 10, and estimate the vehicle's position on a road map.

[0032] As described above, the locator unit estimates the position of vehicle 1 (vehicle position) on a road map based on the positioning signal received through communication unit 20 or information detected by sensor unit 10, and is then able to determine the road type, etc. of the road on which vehicle 1 is traveling based on the estimated vehicle position on the road map.

[0033] The locator unit is capable of updating the road map information stored in the road map DB 41 to the latest version using road map information acquired through external communication (roadside-to-vehicle communication and vehicle-to-vehicle communication) via the communication unit 20. This information update is performed not only for static information but also for quasi-static information, quasi-dynamic information, and dynamic information. As a result, the road map information includes road information and traffic information acquired through communication with the outside of the vehicle, and information on moving objects such as vehicles traveling on roads is updated in approximately real time.

[0034] The locator unit verifies road map information based on the traveling environment information recognized as described above, and updates the road map information stored in the road map DB 41 to the latest version. This information update is performed not only on static information, but also on semi-static information, semi-dynamic information, and dynamic information. As a result, information on moving objects such as vehicles traveling on roads recognized as described above is updated in real time.

[0035] The control unit 30 further includes a driving control unit 36, for example, as shown in FIG. 1. The driving control unit 36 ​​is capable of performing driving control using various data and various control signals acquired by a data acquisition unit 32 (described later). The driving control unit 36 ​​is capable of controlling the driving of the vehicle 1 (for example, the torque of the prime mover 70, the amount of brake depression, and the steering angle of the steering wheel). The driving control unit 36 ​​includes an accelerator control unit 37, a brake control unit 38, and a steering control unit 39, for example, as shown in FIG. 1.

[0036] Accelerator control unit 37 is capable of controlling the torque of prime mover 70 based on a required torque corresponding to the amount of accelerator pedal depression by the driver of vehicle 1. Accelerator control unit 37 is further capable of controlling the torque of prime mover 70 based on the required torque. Prime mover 70 is configured to drive the steered wheels of vehicle 1, and is capable of driving the steered wheels of vehicle 1 in accordance with the required torque input from accelerator control unit 37.

[0037] The brake control unit 38 is capable of controlling the torque of the brake 80 based on a required torque corresponding to the amount of brake pedal depression by the driver of the vehicle 1. The brake control unit 38 is further capable of controlling the torque of the brake 80 based on the required torque. The brake 80 is configured to brake the steered wheels of the vehicle 1, and is capable of braking the steered wheels of the vehicle 1 in accordance with the required torque input from the brake control unit 38.

[0038] The steering control unit 39 is capable of deriving a steering assist torque that assists the steering torque generated by the driver's steering wheel operation and setting an EPS torque corresponding to the derived steering assist torque. The steering control unit 39 is capable of outputting a control signal to the EPS motor 90 so that the output torque of the EPS motor 90 becomes the set EPS torque. The EPS motor 90 generates an output torque based on the input control signal and is capable of controlling the steering angle of the steering wheel.

[0039] The accelerator control unit 37, the brake control unit 38, and the steering control unit 39 may be configured to include, for example, a CPU, etc. In this case, the accelerator control unit 37, the brake control unit 38, and the steering control unit 39 are able to perform the various driving controls described above by, for example, executing control software 42 stored in a storage unit 40.

[0040] The control unit 30 further includes a replacement proposal unit 31, as shown in FIG. 1, for example. When the vehicle 1 reaches a predetermined situation or state, the replacement proposal unit 31 is capable of proposing replacement with new parts or software that can improve the situation or state. A "new part" refers to a part of the same type as the existing part, but is more effective than the part (existing part) used in the vehicle 1. "New software" refers to software that cannot be used in the vehicle 1 due to contracts, settings, etc., at the stage before the replacement proposal is made (or before a determination is made by the situation state determination unit 33, which will be described later).

[0041] 1, the exchange proposing unit 31 includes a data acquiring unit 32, a situation state determining unit 33, an improvement condition deriving unit 34, and a notification control unit 35. The data acquiring unit 32 corresponds to a specific example of an "acquiring unit" in the present disclosure. The situation state determining unit 33, the improvement condition deriving unit 34, and the notification control unit 35 correspond to a specific example of a "control unit" in the present disclosure.

[0042] The data acquisition unit 32 is capable of periodically acquiring data on the situation or state of the vehicle 1. Specifically, the data acquisition unit 32 is capable of acquiring various data acquired from the sensor unit 10, various data acquired from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1. Based on the acquired various data and various control signals, the data acquisition unit 32 is capable of acquiring, for example, road surface condition data Dc, vertical G data (vertical acceleration data) Dd, output suppression control data De of the prime mover 70, communication status data Df, deceleration data Dg, traveling position data Dh, and braking force data Di.

[0043] The road surface condition data Dc is data about the condition (e.g., dry, wet, snow, ice) of the road surface ahead of the vehicle 1. The data acquisition unit 32 is capable of generating the road surface condition data Dc by, for example, performing a predetermined process on the image data Da.

[0044] The vertical G data Dd is data on the vertical acceleration that occurs in the vehicle 1 when the vehicle 1 goes over an uneven road surface. The data acquisition unit 32 can obtain the vertical G data Dd by, for example, extracting vertical acceleration data from the acceleration data in three directions obtained by an acceleration sensor.

[0045] The output reduction control data De is data indicating the presence or absence of a control signal for reducing the output of the prime mover 70, which is output from the cruise control unit 36 ​​to the accelerator control unit 37 due to an increase in the oil temperature of the vehicle 1. The data acquisition unit 32 is able to acquire the output reduction control data De by, for example, detecting a control signal generated in the cruise control unit 36.

[0046] The communication status data Df is communication status data for at least one of vehicle-to-vehicle communication, road-to-vehicle communication, and satellite communication. The data acquisition unit 32 can acquire the communication status data Df by, for example, detecting the communication status of the communication unit 20.

[0047] The deceleration data Dg is data regarding large deceleration occurring in the vehicle 1. Large deceleration occurs in the vehicle 1, for example, when the driver presses the brake pedal hard or when the "pre-crash safety" is activated in the driving control unit 36. "Pre-crash safety" refers to sudden braking control that is activated when it is determined that there is a high possibility that the vehicle 1 will collide with a preceding vehicle in the direction of travel of the vehicle 1. The data acquisition unit 32 is capable of acquiring, as the deceleration data Dg, the acceleration data in the longitudinal direction when it is detected that the acceleration data in the longitudinal direction included in the acceleration data in three directions obtained by the acceleration sensor exceeds a predetermined threshold value, or when it is detected that the "pre-crash safety" has been activated in the driving control unit 36.

[0048] The driving position data Dh is data about the lateral position of the vehicle 1 in the driving lane. The data acquisition unit 32 is capable of deriving the distance between the lane marking and the side edge of the vehicle 1 based on the image data Da, for example, and acquiring the derived distance as the driving position data Dh.

[0049] The braking force data Di is data on the braking force (torque of the brake 70) relative to the brake pressure of the vehicle 1. The data acquisition unit 32 is capable of calculating the braking force data Di based on, for example, forward / rearward acceleration data included in the acceleration data in three directions obtained by an acceleration sensor. The data acquisition unit 32 may be capable of acquiring, for example, data on the braking force (torque of the brake 70) obtained from a brake torque sensor as the braking force data Di.

[0050] The situation state determination unit 33 is capable of processing data periodically acquired by the data acquisition unit 32. When the situation state determination unit 33 acquires various data from the data acquisition unit 32, it is capable of determining whether or not the situation or state is causing the driver (occupant) of the vehicle 1 to feel uncomfortable, based on the acquired various data. The "situation or state causing discomfort" includes, for example, a situation or state requiring improvement that the driver of the vehicle 1 feels would like to improve. The "situation or state causing discomfort" includes, for example, a dangerous situation or state that exposes the driver of the vehicle 1 to danger.

[0051] The situation state determination unit 33 is capable of determining whether or not an improvement-requiring situation or state has occurred due to the vertical acceleration of the vehicle 1, based on the data (road surface state data Dc, vertical G data Dd) acquired by the data acquisition unit 32. The situation state determination unit 33 is capable of determining whether or not an improvement-requiring situation or state has occurred due to output suppression control of the prime mover 70 of the vehicle 1, which is caused by an increase in the oil temperature of the vehicle 1, based on the data (communication status data Df) acquired by the data acquisition unit 32. The situation state determination unit 33 is capable of determining whether or not an improvement-requiring situation or state has occurred due to a communication interruption between the vehicle 1 and the server device, based on the data (communication status data Df) acquired by the data acquisition unit 32.

[0052] The situation state determination unit 33 is capable of determining whether or not a dangerous situation or state has occurred due to the deceleration of the vehicle 1, based on the data (deceleration data Dg) acquired by the data acquisition unit 32. The situation state determination unit 33 is capable of determining whether or not a situation or state requiring improvement has occurred due to the vehicle 1 deviating from its travel lane, based on the data (travel position data Dh) acquired by the data acquisition unit 32. The situation state determination unit 33 is capable of determining whether or not a situation or state requiring improvement has occurred due to a decrease in braking force relative to the brake pressure of the vehicle 1, based on the data (braking force data Di) acquired by the data acquisition unit 32.

[0053] When the driver of the vehicle 1 is in a situation or state where the driver feels uncomfortable, the improvement condition derivation unit 34 is capable of deriving conditions for the control software or the control device that can alleviate the driver's discomfort. When the vehicle 1 is in an improvement-required situation or state, the improvement condition derivation unit 34 is capable of deriving, as the condition for the control software or the control device, conditions for the control software or the control device that can improve the improvement-required situation or state under the same or similar conditions as when the vehicle 1 is in the improvement-required situation or state. When the driver of the vehicle 1 is in a dangerous situation or state, the improvement condition derivation unit 34 is capable of deriving, as the condition for the control software or the control device, conditions for the control software or the control device that can improve the dangerous situation or state under the same or similar conditions as when the driver of the vehicle 1 is in the dangerous situation or state.

[0054] When the improvement-requiring situation or state is caused by the vertical acceleration of the vehicle 1, the improvement condition derivation unit 34 is capable of deriving, as the condition of the control software or the control device, suspension control software or suspension conditions that enable the vehicle 1 to travel so as to reduce the vertical acceleration under the same or similar conditions as when the vehicle 1 is in the improvement-requiring situation or state.When the improvement-requiring situation or state is caused by output suppression control of the prime mover 70 of the vehicle 1 due to an increase in the oil temperature of the vehicle 1, the improvement condition derivation unit 34 is capable of deriving, as the condition of the control device, conditions for an oil cooler having an oil cooling capacity that does not perform output suppression control under the same or similar conditions as when the vehicle 1 is in the improvement-requiring situation or state.When the improvement-requiring situation or state is caused by a communication interruption between the vehicle 1 and the server device, the improvement condition derivation unit 34 is capable of deriving, as the condition of the control device, conditions for a communication device that can communicate with the server device in the area where the communication interruption occurred.

[0055] When the dangerous situation or dangerous state is caused by the deceleration of the vehicle 1, the improvement condition derivation unit 34 is capable of deriving, as the control software condition, a driving control software condition that enables the vehicle 1 to drive so that the deceleration is reduced under the same or similar conditions as when the driver of the vehicle 1 is in the dangerous situation or dangerous state. When the dangerous situation or dangerous state is caused by the vehicle 1 deviating from the driving lane, the improvement condition derivation unit 34 is capable of deriving, as the control software condition, a driving control software condition that enables the vehicle 1 to drive so that the degree of deviation of the vehicle 1 from the driving lane is reduced under the same or similar conditions as when the driver of the vehicle 1 is in the dangerous situation or dangerous state. When the dangerous situation or dangerous state is caused by a decrease in braking force, the improvement condition derivation unit 34 is capable of deriving, as the control device condition, a brake condition that enables the vehicle 1 to drive so that a decrease in braking force relative to the brake pressure of the vehicle 1 due to an increase in the brake temperature of the vehicle 1 is reduced under the same or similar conditions as when the driver of the vehicle 1 is in the dangerous situation or dangerous state.

[0056] The notification control unit 35 is capable of reading information about control software or control devices that satisfy the conditions derived by the improvement condition derivation unit 34 from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50. The notification control unit 35 is capable of outputting the information read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50 to the display unit 60 or the terminal device 100 owned by the driver of the vehicle 1.

[0079] Incidentally, when an instruction to apply control software that satisfies the derived conditions to the vehicle 1 is input from the driver of the vehicle 1, the control unit 30 (replacement proposal unit 31) may be capable of executing a process to make the control software that satisfies the derived conditions available to the vehicle 1. For example, the control unit 30 (replacement proposal unit 31) may be capable of acquiring control software that satisfies the derived conditions from an external device via the communication unit 20 or the like, and installing the acquired control software in a predetermined CPU or the like of the driving control unit 36.

[0080] [effect] Next, the effects of the vehicle 1 according to the first embodiment of the present disclosure will be described.

[0081] In this embodiment, when the driver of vehicle 1 is in a situation or state where he or she feels uncomfortable, conditions for the control software or control device that can alleviate the driver's discomfort are derived. Then, information about the control software or control device that satisfies the derived conditions is read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50, and the read information is output to the display unit 60 or the terminal device 100 of the vehicle 1. As such, in this embodiment, when the driver of vehicle 1 experiences a situation or state where he or she feels uncomfortable, a proposal is made to replace the control software or control device that can improve the situation or state where he or she feels uncomfortable. This allows the driver of vehicle 1 to understand the need to replace the control software or control device based on his or her own experience. Therefore, the driver of vehicle 1 can be effectively encouraged to replace the control software or control device with new control software or control device.

[0082] In this embodiment, when the vehicle 1 is in an improvement-requiring situation or a state requiring improvement, conditions for the control software or the control device that can improve the improvement-requiring situation or the state requiring improvement under conditions that are the same or similar to those when the vehicle 1 is in the improvement-requiring situation or the state requiring improvement are derived as conditions for the control software or the control device. Then, information about the control software or the control device that satisfies the derived conditions is read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50, and the read information is output to the display unit 60 or the terminal device 100 of the vehicle 1. As such, in this embodiment, when the driver of the vehicle 1 experiences the improvement-requiring situation or the state requiring improvement, a proposal is made to replace the control software or the control device that can improve the improvement-requiring situation or the state requiring improvement. This allows the driver of the vehicle 1 to understand the need to replace the control software or the control device based on his or her own experience. Therefore, the driver of the vehicle 1 can be effectively encouraged to replace the control software or the control device with new control software or the control device.

[0083] In this embodiment, when the driver of vehicle 1 is in a dangerous situation or dangerous state, conditions for the control software or control device that can improve the dangerous situation or dangerous state under the same or similar conditions as when the driver of vehicle 1 is in the dangerous situation or dangerous state are derived as conditions for the control software or control device. Then, information about the control software or control device that satisfies the derived conditions is read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50, and the read information is output to the display unit 60 or the terminal device 100 of the vehicle 1. As such, in this embodiment, when the driver of vehicle 1 experiences a dangerous situation or dangerous state, a proposal is made to replace the control software or control device that can improve the dangerous situation or dangerous state. This allows the driver of vehicle 1 to understand the need to replace the control software or control device based on his or her own experience. Therefore, the driver of vehicle 1 can be effectively encouraged to replace the control software or control device with new control software or control device.

[0084] In this embodiment, when an instruction to apply control software that satisfies the derived conditions is input, a process may be executed to make the control software that satisfies the derived conditions available to the vehicle 1. In this case, the driver of the vehicle 1 can use the new control software at the timing when he or she understands the need to replace the control software. As a result, the driver of the vehicle 1 can immediately experience the effects of the new control software, and it is expected that he or she will respond very positively to the next replacement proposal.

If the calculation result indicates that the output suppression control of the prime mover 70 is not performed, the improvement condition derivation unit 34 may be configured to output information about the oil cooler read from the database (replacement parts DB 51) of the storage unit 50 to the display unit 60 or the terminal device 100. If the calculation result indicates that communication with an external device is possible in the area where communication was interrupted, the improvement condition derivation unit 34 may be configured to output information about the communication device read from the database (replacement parts DB 51) of the storage unit 50 to the display unit 60 or the terminal device 100.

[0096] (Suspension and suspension control software) The control unit 30 first acquires road surface condition data Dc and vertical G data Dd using various data obtained from the sensor unit 10, various data obtained from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1 (step S701). The control unit 30 determines whether the vertical G data Dd is excessive under the road surface conditions indicated by the road surface condition data Dc (step S702). If the control unit 30 determines that the vertical G data Dd is excessive under the road surface conditions indicated by the road surface condition data Dc (step S702; Y), it reads out suspension control software or suspension specifications different from the suspension control software or suspension applied to the vehicle 1 from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50 (step S703).

[0097] Based on the read specifications, the control unit 30 performs a calculation to determine whether or not the vehicle 1 can be driven so as to reduce the vertical G data Dd under the same or similar conditions as those under which the excessive vertical G data Dg was obtained when the suspension control software or suspension read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50 is applied to the vehicle 1 (step S704). If the calculation results in a decrease in the vertical acceleration of the vehicle 1 (step S704; Y), the control unit 30 reads information about the suspension control software or suspension that can reduce the vertical acceleration of the vehicle 1 from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50 (step S705). The control unit 30 outputs the read information to the display unit 60 or to the terminal device 100 via the communication unit 20 (step S706).

[0098] When the terminal device 100 receives the information from the control unit 30, it displays the received information. For example, when the terminal device 100 receives the information from the control unit 30 as an email, a message on social media, or the like, it displays the received email, message on social media, or the like on its display screen in accordance with the terminal operation of the driver of the vehicle 1. For example, when a video signal including the information is received from the control unit 30, the display unit 60 displays an image corresponding to the input video signal on its display screen. In this way, when the driver of the vehicle 1 experiences a situation or condition that makes the driver feel uncomfortable, the display unit 60 and the terminal device 100 suggest suspension control software or a suspension replacement that can improve the situation or condition.

[0099] (oil cooler) The control unit 30 first acquires output reduction control data De using various data obtained from the sensor unit 10, various data obtained from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1 (step S801). The control unit 30 determines whether a control signal for reducing the output of the prime mover 70 is output in the output reduction control data De (step S802). If the control unit 30 determines that a control signal for reducing the output of the prime mover 70 is output in the output reduction control data De (step S802; Y), it reads out specifications of an oil cooler different from the oil cooler applied to the vehicle 1 from the database (replacement part DB 51) of the storage unit 50 (step S803).

[0100] Based on the read specifications, the control unit 30 performs a calculation to determine whether a control signal for suppressing the output of the prime mover 70 will be output under conditions that are the same as or similar to the situation or state in which a control signal for suppressing the output of the prime mover 70 was output when the oil cooler read from the database (replacement part DB 51) of the storage unit 50 is applied to the vehicle 1 (step S804). If the calculation results in a determination that a control signal for suppressing the output of the prime mover 70 will not be output (step S804; Y), the control unit 30 reads information about oil coolers having an oil-cooling capacity for which a control signal for suppressing the output of the prime mover 70 will not be output from the database (replacement part DB 51) of the storage unit 50 (step S805). The control unit 30 outputs the read information to the display unit 60 or to the terminal device 100 via the communication unit 20 (step S806).

[0101] When the terminal device 100 receives the information from the control unit 30, it displays the received information. For example, when the terminal device 100 receives the information from the control unit 30 as an email, a message on social media, or the like, it displays the received email, message on social media, or the like on a display screen in accordance with the terminal operation of the driver of the vehicle 1. For example, when a video signal including the information is received from the control unit 30, the display unit 60 displays an image corresponding to the input video signal on the display screen. In this way, when the driver of the vehicle 1 experiences a situation or condition that makes the driver feel uncomfortable, the display unit 60 and the terminal device 100 suggest replacing the oil cooler, which can improve the situation or condition that makes the driver feel uncomfortable.

[0102] (Communication equipment) The control unit 30 first acquires communication status data Df by using various data obtained from the sensor unit 10, various data obtained from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1 (step S901). The control unit 30 determines whether or not communication has been interrupted with at least one communication device among vehicle-to-vehicle communication, road-to-vehicle communication, and satellite communication in the communication status data Df (step S902). If the control unit 30 determines that communication has been interrupted with at least one communication device among vehicle-to-vehicle communication, road-to-vehicle communication, and satellite communication in the communication status data Df (step S902; Y), it reads out specifications of a communication device different from the communication device applied to the vehicle 1 from the database (replacement part DB 51) of the storage unit 50 (step S903).

[0103] Based on the read specifications, the control unit 30 performs a calculation to determine whether the vehicle 1 will be able to communicate in the area where the communication disruption occurred when the communication device read from the database (replacement part DB 51) of the storage unit 50 is applied to the vehicle 1 (step S904). If the calculation result shows that the vehicle 1 will be able to communicate in the area where the communication disruption occurred (step S904; Y), the control unit 30 reads information about the communication device with which the vehicle 1 can communicate in the area where the communication disruption occurred from the database (replacement part DB 51) of the storage unit 50 (step S905). The control unit 30 outputs the read information to the display unit 60 or the terminal device 100 via the communication unit 20 (step S906).

[0104] When the terminal device 100 receives the information from the control unit 30, it displays the received information. For example, when the terminal device 100 receives the information from the control unit 30 as an email or a message on an SNS or the like, it displays the received email or message on a display screen in accordance with the terminal operation of the driver of the vehicle 1. For example, when a video signal including the information is input from the control unit 30, the display unit 60 displays an image corresponding to the input video signal on the display screen. In this way, when the driver of the vehicle 1 experiences a situation or condition that makes him / her feel uncomfortable, the display unit 60 and the terminal device 100 suggest replacing a communication device that can improve the situation or condition.

[0105] (Drive control software applied during sudden braking) The control unit 30 first acquires deceleration data Dg using various data obtained from the sensor unit 10, various data obtained from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1 (step S1001). The control unit 30 determines whether the deceleration is excessive based on the deceleration data Dg (step S1002). If the control unit 30 determines that the deceleration is excessive (step S1002; Y), it reads out specifications of driving control software applied to the vehicle 1 that is different from the driving control software applied under sudden braking from the database (exchange software DB 52) of the storage unit 50 (step S1003).

[0106] Based on the read specifications, the control unit 30 performs a calculation to determine whether the deceleration of the vehicle 1 decreases under conditions identical or similar to the situation or state in which the vehicle 1 experienced excessive deceleration when the driving control software read from the database (exchange software DB 52) of the storage unit 50 is applied to the vehicle 1 (step S1004). If the result shows that the deceleration decreases (step S1004; Y), the control unit 30 reads information about driving control software that decreases the deceleration from the database (exchange software DB 52) of the storage unit 50 (step S1005). The control unit 30 outputs the read information to the display unit 60 or the terminal device 100 via the communication unit 20 (step S1006).

[0107] When the terminal device 100 receives the information from the control unit 30, it displays the received information. For example, when the terminal device 100 receives the information from the control unit 30 as an email or a message on an SNS or the like, it displays the received email or message on a display screen in accordance with the terminal operation of the driver of the vehicle 1. For example, when a video signal including the information is received from the control unit 30, the display unit 60 displays an image corresponding to the input video signal on the display screen. In this way, when the driver of the vehicle 1 experiences a situation or condition that makes the driver feel uncomfortable, the display unit 60 and the terminal device 100 suggest replacing the driving control software with software that can improve the situation or condition.

[0108] (Drive control software applied when the vehicle departs from its lane) The control unit 30 first acquires driving position data Dh by using various data obtained from the sensor unit 10, various data obtained from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1 (step S1101). The control unit 30 determines whether the vehicle 1 has deviated from the driving lane based on the driving position data Dh (step S1102). If the control unit 30 determines that the vehicle 1 has deviated from the driving lane (step S1102; Y), it reads out specifications of driving control software applied to the vehicle 1 that is different from the driving control software applied under lane deviation from the database (exchange software DB 52) of the storage unit 50 (step S1103).

[0109] Based on the read specifications, the control unit 30 performs a calculation to determine whether or not it is possible to cause the vehicle 1 to travel so as to reduce the degree of deviation from the travel lane by the vehicle 1 under conditions that are the same as or similar to the situation or state in which the vehicle 1 deviated from the travel lane when the driving control software read from the database (exchange software DB 52) of the storage unit 50 is applied to the vehicle 1 (step S1104). If the control unit 30 determines that it is possible to cause the vehicle 1 to travel so as to reduce the degree of deviation from the travel lane by the vehicle 1 (step S1104; Y), it reads information about driving control software that can cause the vehicle 1 to travel so as to reduce the degree of deviation from the travel lane by the vehicle 1 from the database (exchange software DB 52) of the storage unit 50 (step S1105). The control unit 30 outputs the read information to the display unit 60 or the terminal device 100 via the communication unit 20 (step S1106).

[0110] When the terminal device 100 receives the information from the control unit 30, it displays the received information. For example, when the terminal device 100 receives the information from the control unit 30 as an email or a message on an SNS or the like, it displays the received email or message on a display screen in accordance with the terminal operation of the driver of the vehicle 1. For example, when a video signal including the information is received from the control unit 30, the display unit 60 displays an image corresponding to the input video signal on the display screen. In this way, when the driver of the vehicle 1 experiences a situation or condition that makes the driver feel uncomfortable, the display unit 60 and the terminal device 100 suggest replacing the driving control software with software that can improve the situation or condition.

[0111] (brake) The control unit 30 first acquires braking force data Di by using various data obtained from the sensor unit 10, various data obtained from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1 (step S1201). Based on the braking force data Di, the control unit 30 determines whether the braking force (torque of the brakes 70) relative to the braking pressure of the vehicle 1 is equal to or less than expected (step S1202). If the control unit 30 determines based on the braking force data Di that the braking force (torque of the brakes 70) relative to the braking pressure of the vehicle 1 is equal to or less than expected (step S1202; Y), the control unit 30 reads out specifications of brakes different from those applied to the vehicle 1 from the database (replacement part DB 51) of the storage unit 50 (step S1203).

[0112] Based on the read specifications, the control unit 30 performs a calculation to determine whether or not, when the brakes read from the database (replacement part DB 51) of the storage unit 50 are applied to the vehicle 1, the vehicle 1 can be driven so that a decrease in braking force relative to the brake pressure of the vehicle 1 caused by an increase in brake temperature of the vehicle 1 is reduced under the same or similar conditions as the situation or state in which the braking force relative to the brake pressure of the vehicle 1 (torque of the brakes 70) becomes equal to or lower than expected (step S1204). If the calculation results in a decrease in braking force relative to the brake pressure of the vehicle 1 caused by an increase in brake temperature of the vehicle 1 being reduced (step S1204; Y), the control unit 30 reads information about brakes that can be used to drive the vehicle 1 so that a decrease in braking force relative to the brake pressure of the vehicle 1 caused by an increase in brake temperature of the vehicle 1 is reduced from the database (replacement part DB 51) of the storage unit 50 (step S1205). The control unit 30 outputs the read information to the display unit 60 or to the terminal device 100 via the communication unit 20 (step S1206).

[0113] When the terminal device 100 receives the information from the control unit 30, it displays the received information. For example, when the terminal device 100 receives the information from the control unit 30 as an email, a message on social media, or the like, it displays the received email, message on social media, or the like on a display screen in accordance with the terminal operation of the driver of the vehicle 1. For example, when a video signal including the information is received from the control unit 30, the display unit 60 displays an image corresponding to the input video signal on the display screen. In this way, when the driver of the vehicle 1 experiences a situation or condition that makes him or her feel uncomfortable, the display unit 60 and the terminal device 100 suggest brake replacement that can improve the situation or condition that makes him or her feel uncomfortable.

[0114] In this modification, when the vehicle 1 is in a situation requiring improvement or a state requiring improvement, specifications of control software or a control device different from the control software or a control device applied to the vehicle 1 are read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50. Based on the read specifications, a calculation is performed to determine whether the situation requiring improvement or the state requiring improvement of the vehicle 1 can be alleviated when the control software or the control device read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50 is applied to the vehicle 1. If the result of the calculation shows that the situation requiring improvement or the state requiring improvement of the vehicle 1 can be alleviated, information about the control software or the control device read from the database (replacement software DB 52 or replacement part DB 51) of the storage unit 50 is output to the display unit 60 or the terminal device 100 of the vehicle 1. In this way, in this modification, when the driver of the vehicle 1 experiences a situation requiring improvement or the state requiring improvement, a proposal to replace the control software or the control device that can improve the situation requiring improvement or the state requiring improvement is made. This allows the driver of the vehicle 1 to understand the need for replacing the control software or the control device based on his or her own experience. Therefore, the driver of the vehicle 1 can be effectively prompted to replace the control software or control device with new software.

[0115] In this modification, when the driver of vehicle 1 is in a dangerous situation or state, specifications of control software or control devices different from the control software or control device applied to vehicle 1 are read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 50. Based on the read specifications, a calculation is performed to determine whether or not the dangerous situation or state of the driver of vehicle 1 can be alleviated when the control software or control device read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 50 is applied to vehicle 1. If the result of the calculation shows that the dangerous situation or state of the driver of vehicle 1 can be alleviated, information about the control software or control device read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 50 is output to display unit 60 or terminal device 100 of vehicle 1. In this way, in this modification, when the driver of vehicle 1 experiences a dangerous situation or state, a proposal to replace the control software or control device that can improve the dangerous situation or state is made. This allows the driver of vehicle 1 to understand the need for replacing the control software or control device based on his or her own experience. Therefore, the driver of the vehicle 1 can be effectively prompted to replace the control software or control device with new software.

[0116] 14 shows a modified functional block diagram of the vehicle 1 according to the first embodiment. In this modified example, the vehicle 1 is capable of communicating with, for example, a server device 200 shown in FIG. 15 via the communication device 20, and the storage unit 50 is omitted from the configuration. The vehicle 1 is capable of transmitting various data obtained from the sensor unit 10, various data obtained from the outside via the communication unit 20, and various control signals for various devices of the vehicle 1 to the server device 200 via the communication unit 20.

[0117] The server device 200 includes, for example, a communication unit 210, a storage unit 220, and a control unit 230, as shown in FIG. 15. The communication unit 210 is a communication interface capable of communicating with the vehicle 1 of FIG. 14. The communication unit 210 is capable of outputting data received from the vehicle 1 of FIG. 14 to the control unit 230. The storage unit 220 is, for example, configured with a nonvolatile memory, such as an EEPROM, a flash memory, or a resistance-change memory. For example, as shown in FIG. 15, the storage unit 220 stores a replacement part DB 51 and a replacement software DB 52.

[0118] The control unit 230 is capable of outputting information about the control software or the control device contained in the database (replacement software DB 52 or replacement part DB 51) of the storage unit 220 to the vehicle 1 via the communication unit 220 in response to a request from the vehicle 1. The control unit 230 is configured to include, for example, a CPU. A program is loaded into the control unit 230 for outputting, for example, in response to a request from the vehicle 1, information about the control software or the control device contained in the database (replacement software DB 52 or replacement part DB 51) of the storage unit 220 to the vehicle 1 via the communication unit 220.

[0119] In this modification, the database (replacement software DB52 or replacement part DB51) is provided in the server device 200. This allows a large number of vehicles 1 to access the server device 200 and obtain information about the control software or control device contained in the database (replacement software DB52 or replacement part DB51). Furthermore, compared to providing a database (replacement software DB52 or replacement part DB51) for each vehicle 1, the effort required to update the database (replacement software DB52 or replacement part DB51) can be minimized.

[0120] 4. Second Embodiment [Configuration example] Next, a vehicle 2 according to a second embodiment of the present disclosure will be described. In the following, descriptions of components having the same reference numerals as those assigned to the components in the vehicle 1 according to the first embodiment will be omitted as appropriate.

Exchange proposal unit 22 is configured such that the situation state determination unit 33 and the improvement condition derivation unit 34 are omitted from the exchange proposal unit 31. Exchange proposal unit 22 is capable of outputting various data (e.g., road surface condition data Dc, vertical G data (vertical acceleration data) Dd, output suppression control data De of prime mover 70, communication status data Df, deceleration data Dg, traveling position data Dh, and braking force data Di) acquired by data acquisition unit 32 to server device 300 via communication unit 20.

[0123] As shown in FIG. 17 , the server device 300 includes a communication unit 310, a storage unit 320, and a control unit 330. The communication unit 310 corresponds to a specific example of a "receiving unit" or a "transmitting unit" in the present disclosure.

The communication unit 310 is a communication interface capable of communicating with the vehicle 2 and the terminal device 100. The communication unit 310 is capable of outputting data received from the vehicle 2 to the control unit 330. The communication unit 310 is further capable of transmitting processing data input from the control unit 330 to the vehicle 2 or the terminal device 100. The processing data includes, for example, information about the control software or control device for the replacement proposal read from the databases (the replacement part DB 51 and the replacement software DB 52) of the storage unit 320.

[0124] The storage unit 320 is configured, for example, by a nonvolatile memory, such as an EEPROM, a flash memory, a resistance change memory, etc. The storage unit 320 stores, for example, databases (a replacement part DB 51 and a replacement software DB 52) as shown in FIG.

[0125] The control unit 330 is capable of performing various data processing using data received from the vehicle 2 and outputting the processing results to the vehicle 1 via the communication unit 220.

The data acquisition unit 331 is capable of acquiring data transmitted from the vehicle 2 via the communication unit 310 (e.g., road surface condition data Dc, vertical G data (vertical acceleration data) Dd, output suppression control data De of the prime mover 70, communication status data Df, deceleration data Dg, traveling position data Dh, and braking force data Di).

[0126] The control unit 230 is configured to include, for example, a CPU, etc. A program for executing data processing similar to the various data processing in the exchange proposal unit 31 according to the first embodiment and its modified examples is loaded into the control unit 230, and the control unit 230 is capable of executing data processing similar to the various data processing in the exchange proposal unit 31 according to the first embodiment and its modified examples.

[0127] [effect] Next, the effects of the vehicle 2 according to the second embodiment of the present disclosure will be described.

[0128] In this embodiment, when the driver of vehicle 2 is in a situation or state where he or she feels uncomfortable, conditions for the control software or control device that can alleviate the driver's discomfort are derived. Then, information about the control software or control device that satisfies the derived conditions is read from the database (replacement software DB 52 or replacement part DB 51) in the storage unit 320, and the read information is transmitted to the vehicle 2 or the terminal device 100. The information transmitted to the vehicle 2 is output to the display unit 60, and the information transmitted to the terminal device 100 is output to the display unit of the terminal device 100. As described above, in this embodiment, when the driver of vehicle 2 experiences a situation or state where he or she feels uncomfortable, a proposal is made to replace the control software or control device that can improve the situation or state where he or she feels uncomfortable. This allows the driver of vehicle 2 to understand the need to replace the control software or control device based on his or her own experience. Therefore, the driver of vehicle 2 can be effectively encouraged to replace the control software or control device with new control software or control device.

[0129] In this embodiment, when the vehicle 2 is in an improvement-requiring situation or a state requiring improvement, conditions for the control software or the control device that can improve the improvement-requiring situation or the state requiring improvement under the same or similar conditions as when the vehicle 2 is in the improvement-requiring situation or the state requiring improvement are derived as conditions for the control software or the control device. Then, information about the control software or the control device that satisfies the derived conditions is read from the database (the replacement software DB 52 or the replacement part DB 51) in the storage unit 320, and the read information is transmitted to the vehicle 2 or the terminal device 100. The information transmitted to the vehicle 2 is output to the display unit 60, and the information transmitted to the terminal device 100 is output to the display unit of the terminal device 100. Thus, in this embodiment, when the driver of the vehicle 2 experiences the improvement-requiring situation or the state requiring improvement, a proposal is made to replace the control software or the control device that can improve the improvement-requiring situation or the state requiring improvement. This allows the driver of the vehicle 2 to understand the need to replace the control software or the control device based on his or her own experience. Therefore, the driver of the vehicle 2 can be effectively encouraged to replace the control software or the control device with new control software or the control device.

[0130] In this embodiment, when the driver of vehicle 2 is in a dangerous situation or dangerous state, conditions for the control software or control device that can improve the dangerous situation or dangerous state under the same or similar conditions as when the driver of vehicle 2 is in the dangerous situation or dangerous state are derived as conditions for the control software or control device. Then, information about the control software or control device that satisfies the derived conditions is read from the database (replacement software DB 52 or replacement part DB 51) in the storage unit 320, and the read information is transmitted to the vehicle 2 or the terminal device 100. The information transmitted to the vehicle 2 is output to the display unit 60, and the information transmitted to the terminal device 100 is output to the display unit of the terminal device 100. As such, in this embodiment, when the driver of vehicle 2 experiences a dangerous situation or dangerous state, a proposal is made to replace the control software or control device that can improve the dangerous situation or dangerous state. This allows the driver of vehicle 2 to understand the need to replace the control software or control device based on his or her own experience. Therefore, the driver of vehicle 2 can be effectively encouraged to replace the control software or control device with new control software or control device.

[0131] In this embodiment, when an instruction to apply control software that satisfies the derived conditions is input, a process may be executed in vehicle 2 to make the control software that satisfies the derived conditions available to vehicle 2. In this case, the driver of vehicle 2 can use the new control software at the timing when he or she understands the need to replace the control software. As a result, the driver of vehicle 2 can immediately experience the effects of the new control software, and it is expected that he or she will respond very positively to the next replacement proposal.

[0132] In the present embodiment, when vehicle 2 is in an improvement-requiring situation or a state requiring improvement, specifications of control software or a control device different from the control software or a control device applied to vehicle 2 are read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 320. Based on the read specifications, a calculation is performed to determine whether or not the improvement-requiring situation or the state requiring improvement of vehicle 2 can be alleviated when the control software or the control device read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 320 is applied to vehicle 2. If the result of the calculation shows that the improvement-requiring situation or the state requiring improvement of vehicle 2 can be alleviated, information about the control software or the control device read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 320 is output to display unit 60 or terminal device 100 of vehicle 2. As such, in the present embodiment, when the driver of vehicle 2 experiences an improvement-requiring situation or the state requiring improvement, a proposal to replace control software or a control device that can improve the improvement-requiring situation or the state requiring improvement is made. This allows the driver of vehicle 2 to understand the need for replacement of the control software or the control device based on his or her own experience. Therefore, the driver of the vehicle 2 can be effectively prompted to replace the control software or control device with new software.

[0133] In this embodiment, when the driver of vehicle 2 is in a dangerous situation or state, specifications of control software or control devices different from the control software or control device applied to vehicle 2 are read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 320. Based on the read specifications, a calculation is performed to determine whether or not the dangerous situation or state of the driver of vehicle 2 can be alleviated when the control software or control device read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 320 is applied to vehicle 2. If the result of the calculation shows that the dangerous situation or state of the driver of vehicle 2 can be alleviated, information about the control software or control device read from the database (replacement software DB 52 or replacement part DB 51) of storage unit 320 is output to display unit 60 or terminal device 100 of vehicle 2. In this way, in this modification, when the driver of vehicle 2 experiences a dangerous situation or state, a proposal to replace the control software or control device that can improve the dangerous situation or state is made. This allows the driver of vehicle 2 to understand the need for replacing the control software or control device based on his or her own experience. Therefore, the driver of the vehicle 2 can be effectively prompted to replace the control software or control device with new software.
