Technology is disclosed.

JP 2009-128486 A

  In the technique disclosed in Patent Document 1, the travel information obtained on the vehicle side is configured to distinguish whether it is caused by a driving operation of the driver or caused by a malfunction of the vehicle. Absent. Therefore, even when driving information that can reduce the driver's driving evaluation due to a vehicle malfunction (for example, driving information indicating unstable behavior of the vehicle) is obtained, the driving of the driver is evaluated low. There is a problem that the driver's driving quality cannot be accurately diagnosed.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a driving diagnosis system, a server device, and an in-vehicle device that can more accurately diagnose the quality of driving of a driver. There is to do.

  In the driving diagnosis system according to claim 1, the vehicle-mounted device includes diagnostic information recording means for acquiring and recording information about a vehicle malfunction (hereinafter referred to as diagnosis information), and the transmission device of the vehicle-mounted device is a vehicle running The diagnosis information recorded by the diagnosis information recording means is transmitted in addition to the information on the state and / or the operation state (hereinafter referred to as vehicle information), and the driving diagnosis means of the server device transmits the vehicle information transmitted from the vehicle-mounted device. Based on the diagnosis information, a diagnosis regarding the quality of driving of the vehicle driver is performed.

  According to this, not only the vehicle information but also the diagnosis information can be taken into consideration so that the driving diagnosis means can make a diagnosis regarding the driving quality of the vehicle driver, so that a vehicle malfunction occurs based on the diagnosis information. It is possible to more accurately diagnose the driver's driving quality by excluding the vehicle information at the time of driving.

  According to the configuration of the second aspect, the driving diagnosis means detects when a vehicle malfunction is detected based on the time information indicating when the vehicle information is detected and the time information indicating when the vehicle malfunction is detected. Since the diagnosis regarding the driving quality of the driver of the vehicle is performed by excluding the vehicle information thus made, it is possible to more accurately diagnose the driving quality of the driver.

Since one of the insurance premiums is calculated, it is possible to calculate an appropriate insurance premium according to the driving quality of the driver. For example, a driver's vehicle that performs good driving is unlikely to have an accident, so the driver's driving quality can be determined by calculating a low insurance premium for the driver's vehicle that performs good driving or the driver itself. It is possible to calculate an appropriate insurance premium according to the situation.

  According to the configuration of the sixth aspect, in the server device of the company that provides at least one of the rental and sharing services for the vehicle, the service for the driver of the vehicle according to the accurate diagnosis result on the driving quality of the driver Therefore, it is possible to calculate an appropriate usage fee according to whether the driving of the driver is good or bad.

It is possible to calculate an appropriate usage fee according to the quality of driving.

  According to the configuration of claim 7, in the server device of a company that conducts at least one of purchase and trade-in of used cars, the vehicle driver at the time of the transaction according to an accurate diagnosis result on the quality of driving of the driver Therefore, it is possible to calculate an appropriate price according to the driving quality of the driver. For example, it is considered that a driver's vehicle that performs good driving is unlikely to deteriorate, so by calculating a high price for buying a used car or trade-in for a driver who performs good driving, An appropriate price can be calculated.

  In the server device according to claim 8, receiving means for receiving vehicle information and diagnosis information acquired and transmitted by the vehicle-mounted device mounted on the vehicle, and vehicle information and diagnosis information received by the receiving means are also included. And a driving diagnosis means for making a diagnosis on the quality of driving of the driver of the vehicle.

According to this, in the server device, it is possible to exclude the vehicle information when the vehicle malfunction has occurred based on the diagnosis information, and more accurately diagnose the quality of the driving of the driver.

  In the vehicle-mounted device according to claim 10, the vehicle diagnosis driver obtains and records the vehicle information acquired by the vehicle information recording means and the diagnosis information acquired and recorded by the diagnosis information recording means. The diagnosis regarding the quality of driving will be performed. According to this, in the vehicle-mounted device, it is possible to exclude the vehicle information when a vehicle malfunction has occurred based on the diagnosis information, and more accurately diagnose the quality of the driving of the driver.

  According to the configuration of the eleventh aspect, the vehicle information detected when the vehicle malfunction is detected based on the time information indicating the vehicle information detection time and the time information indicating the vehicle malfunction detection time.

FIG. It is a flowchart which shows the flow of the process regarding the driving | operation diagnosis process and insurance premium calculation process in the control part 32. FIG. It is a flowchart which shows an example of the flow of the process relevant to calculation of the usage fee and price in the server apparatus 3 of a rental company or a used car purchase company.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a driving diagnosis system 100 to which the present invention is applied. A driving diagnosis system 100 shown in FIG. 1 includes an in-vehicle terminal 1, a server device 3, and a scan tool 4 mounted on a vehicle. In the present embodiment, the case where the in-vehicle terminal 1 is mounted on a hybrid vehicle (HV) that uses a motor and an engine as a travel drive source will be described as an example.

  First, the schematic configuration of the in-vehicle terminal 1 will be described with reference to FIG. FIG. 2 is a block diagram illustrating a schematic configuration of the in-vehicle terminal 1. As shown in FIG. 2, the in-vehicle terminal 1 includes a dedicated slot 11, an immobilizer ECU 12, a telematics ECU 13, and a communication module 14. The immobilizer ECU 12, the telematics ECU 13, the engine ECU 16, the brake ECU 17, the hybrid ECU (HV_ECU) 18, the cruise ECU 19, and the EPS_ECU 20 are connected to each other by an in-vehicle LAN 21 that complies with a communication protocol such as CAN (controller area network). The in-vehicle terminal 1 corresponds to the in-vehicle device in the claims.

  In the dedicated slot 11, an electronic license 5 in which identification information (for example, driver ID) for identifying an individual is recorded is inserted. The electronic license 5 is carried by a vehicle driver and includes a storage unit such as an IC chip. The dedicated slot 11 reads the driver ID from the storage unit of the inserted electronic license 5. Therefore, the dedicated slot 11 corresponds to the identification information reading means in the claims.

  The immobilizer ECU 12 is composed mainly of a microcomputer comprising a CPU, ROM, RAM, EEPROM, etc., and executes various control programs stored in the ROM based on input information, thereby controlling the start of the vehicle. Various processes related to are executed.

  For example, the immobilizer ECU 12 acquires a key ID read by a communication device (not shown) from a known immobilizer key 6 inserted into a key cylinder of the vehicle. Then, authentication (that is, immobil key authentication) is performed by determining whether or not the acquired key ID matches the registered ID.

  Further, the immobilizer ECU 12 acquires the driver ID read from the electronic license 5 inserted into the dedicated slot 11. Then, authentication (that is, electronic license authentication) is performed by determining whether or not the acquired driver ID is a regular driver ID. Therefore, immobilizer ECU12 is equivalent to the authentication means of a claim. For example, the configuration may be such that authentication is performed by determining whether or not the acquired driver ID matches a registered ID. In addition, when an electronic certificate or electronic signature is given to the driver ID, it is determined whether the driver ID is a regular driver ID based on the electronic certificate, or whether the driver ID is falsified based on the electronic signature. It is good also as a structure which authenticates that it is a regular electronic license by determining.

  And immobilizer ECU12 outputs the engine start permission signal which permits engine start to engine ECU16, when both the authentication by the above-mentioned key ID and the authentication by driver ID are materialized. When the engine start permission signal is input, the engine ECU 16 starts the operation of the fuel injection device and the ignition device. As a result, the engine is started by the fuel being injected into the engine while the starter motor is rotating and the spark plug is ignited. Further, when neither the authentication by the key ID nor the authentication by the driver ID is established, an engine start prohibition signal for prohibiting the engine start is output to the engine ECU 16 to prohibit the engine start. Therefore, the immobilizer ECU 12 corresponds to a start restriction unit in the claims.

  Here, with reference to FIG. 3, a description will be given of a flow of processing relating to starting of the vehicle in the in-vehicle terminal 1. FIG. 3 is a flowchart showing a flow of processing related to starting of the vehicle in the in-vehicle terminal 1. This flow is started when IG-ON is performed.

  First, in step S1, the immobilizer ECU 12 performs the aforementioned immobilizer key authentication, and proceeds to step S2. In step S2, when immobil key authentication is established (YES in step S2), the process proceeds to step S3. If immobil key authentication has not been established (NO in step S2), the process proceeds to step S6.

  In step S3, the immobilizer ECU 12 performs the above-described electronic license authentication and proceeds to step S4. In step S4, if electronic license authentication is established (YES in step S4), the process proceeds to step S5. If the electronic license authentication is not established (NO in step S4), the process proceeds to step S6.

  In step S5, the immobilizer ECU 12 outputs an engine start permission signal to the engine ECU 16, starts the vehicle, and ends the flow. In step S6, the immobilizer ECU 12 outputs an engine start prohibition signal to the engine ECU 16, prohibits engine start, and ends the flow.

  In the present embodiment, the configuration in which immobil key authentication and electronic license authentication are combined is shown. However, the configuration is not limited to this, and a configuration in which electronic license authentication and other than immobil key authentication are combined may be employed. The authentication combined with the electronic license authentication may be authentication performed before starting the engine, and may be combined with authentication at the time of keyless entry, for example. Further, only the electronic license authentication may be configured.

  The engine ECU 16, the brake ECU 17, the HV_ECU 18, the cruise ECU 19, and the EPS_ECU 20 are mainly configured by a microcomputer including a CPU, a ROM, a RAM, an EEPROM, and the like. Further, the engine ECU 16, the brake ECU 17, the HV_ECU 18, the cruise ECU 19, and the EPS_ECU 20 detect information relating to the running state such as the behavior of the vehicle and information relating to the operation state of the vehicle (hereinafter referred to as vehicle information) from signals from various sensors.

Controls TRC (Traction Control System), ESC (Electronic Stability Control) to prevent skidding, and the like.

  The HV_ECU 18 transmits which driving force of the motor or engine to the driving wheel based on information such as the vehicle speed detected from the signal of the vehicle speed sensor and the accelerator opening detected from the signal of the accelerator opening sensor. The processing related to the drive source switching control is performed. The cruise ECU 19 executes processing related to the operation of the auto cruise device based on vehicle information such as the cruise operation state detected from the signal of the cruise switch.

  The EPS_ECU 20 includes a vehicle speed detected from a signal from a vehicle speed sensor, a steering torque detected from a signal from a torque sensor, a steering angle detected from a steering angle sensor signal, a lateral acceleration detected from a signal from an acceleration sensor, and the like. Based on the vehicle information, processing related to steering assist, processing related to steering angle control, and the like are executed.

  The engine ECU 16, the brake ECU 17, the HV_ECU 18, the cruise ECU 19, and the EPS_ECU 20 monitor a malfunction of the vehicle. When a malfunction of the vehicle is detected, diagnosis information (hereinafter referred to as diagnosis information) indicating the location and type of the malfunction is detected. It memorize | stores in non-volatile memories, such as EEPROM. Accordingly, the engine ECU 16, the brake ECU 17, the HV_ECU 18, the cruise ECU 19, and the EPS_ECU 20 correspond to the defect monitoring device in the claims.

  For example, as an example of the diagnosis information, there is information indicating out-of-range of the throttle sensor, information indicating out-of-range of the accelerator sensor, information indicating abnormality in the hydraulic system, information indicating abnormality in the steering angle sensor, and the like.

  In the engine ECU 16, the brake ECU 17, the HV_ECU 18, the cruise ECU 19, and the EPS_ECU 20, a time stamp indicating the detection time is given to the vehicle information and the diagnosis information when the vehicle information is detected or when a vehicle malfunction is detected. For example, the time stamp may be information on the time of detection. The time stamp corresponds to the time information in the claims.

  The telematics ECU 13 is mainly composed of a microcomputer composed of a CPU, ROM, RAM, EEPROM, etc., and executes various control programs stored in the ROM based on input information, thereby providing vehicle information and diagnostic information. The process related to the transmission to the server device 3 is executed.

  When the telematics ECU 13 detects the behavior of the vehicle serving as a trigger, the telematics ECU 13 acquires the vehicle information detected by the ECUs 16 to 20 and records it in a nonvolatile memory such as an EEPROM. Further, when diagnostic information is output from each of the ECUs 16 to 20 to the in-vehicle LAN 21, the telematics ECU 13 acquires the diagnostic information and records it in a nonvolatile memory such as an EEPROM. Therefore, the telematics ECU 13 corresponds to the vehicle information recording means and the diagnostic information recording means. The vehicle information and diagnostic information acquired by the telematics ECU 13 may be recorded in a large-capacity nonvolatile memory such as an HDD other than the memory of the telematics ECU 13.

  Further, the telematics ECU 13 acquires the driver ID of the driver who is driving the vehicle from, for example, the immobilizer ECU 12, and records the driver ID of the driver who is driving the vehicle in association with the vehicle information and diagnostic information. The telematics ECU 13 may acquire the driver ID of the driver who is driving the vehicle from the dedicated slot 11.

  The behavior of the vehicle serving as a trigger is, for example, sudden acceleration, sudden braking, or sudden steering of the vehicle. Specifically, the rapid acceleration is detected based on the fact that the amount of change per unit time (for example, 1 second) of the vehicle speed detected from the signal from the vehicle speed sensor is equal to or greater than a predetermined positive threshold. Good. The predetermined positive threshold referred to here is a value corresponding to the amount of change in vehicle speed that can be said to be sudden acceleration. In addition to the differential value of the vehicle speed, the vehicle's sudden speed based on values such as the amount of change in the engine speed detected from the engine speed sensor signal per unit time and the longitudinal acceleration detected from the acceleration sensor signal. It is good also as a structure which detects acceleration.

  The sudden braking may be detected based on the fact that the longitudinal acceleration detected by the acceleration sensor is equal to or less than a predetermined negative threshold. Here, the predetermined negative threshold is a value corresponding to a deceleration that can be said to be a sudden braking. In addition to longitudinal acceleration, a configuration that detects sudden braking of a vehicle based on values such as the amount of change in vehicle speed per unit time and the amount of change in brake fluid pressure per unit time detected from the signal of the brake pressure sensor It is good.

  The abrupt steering wheel may be detected based on the fact that the absolute value of the change amount per unit time of the steering angle detected from the steering angle sensor signal is equal to or greater than a predetermined threshold. Here, the predetermined threshold value is a value corresponding to the absolute value of the change amount of the steering angle to the extent that it can be said that the steering wheel is abrupt. In addition to the steering angle, a configuration may be adopted in which the sudden handle of the vehicle is detected based on a value such as a lateral acceleration detected from a signal of the acceleration sensor. The vehicle information for detecting the behavior of the vehicle serving as a trigger may be obtained from each sensor or may be obtained from each ECU.

  Recording of vehicle information and diagnostic information is forcibly performed when the vehicle is in operation. The term “during driving” as used herein refers to the period from when the vehicle is started until the vehicle driving source is stopped by turning off the ignition switch (IG-OFF) or the like. May be. What is necessary is just to set it as the structure which discriminate | determines during driving | running | working of a vehicle by vehicle speed etc. Further, “forced” as used herein means that recording is always performed when vehicle information or diagnostic information is acquired.

  Here, the flow of processing relating to the acquisition of vehicle information and diagnosis information in the telematics ECU 13 will be described with reference to FIG. FIG. 4 is a flowchart showing a flow of processing related to acquisition of vehicle information and diagnostic information in the telematics ECU 13. This flow is started when IG-ON is performed. Moreover, each ECU16-20 shall detect the vehicle information sequentially.

  First, in step S11, it is determined whether or not the behavior of the vehicle serving as the trigger is detected. If a trigger is detected (YES in step S11), the process proceeds to step S12. If no trigger is detected (NO in step S11), the process proceeds to step S15.

  In step S12, vehicle information with a time stamp is acquired from each of the ECUs 16 to 20, recorded in the memory, and the process proceeds to step S13. The type of vehicle information acquired from each of the ECUs 16 to 20 is set in advance, and may be configured to acquire the set type of vehicle information. In addition, the vehicle information required for the driving diagnosis process mentioned later shall be set as the kind of vehicle information to acquire.

  In step S13, if diagnostic information is stored in each of the ECUs 16 to 20, that is, if diagnostic information is present (YES in step S13), the process proceeds to step S14. If no diagnosis information is stored in each of the ECUs 16 to 20, that is, if there is no diagnosis information (NO in step S13), the process proceeds to step S15.

  In step S14, the stored diagnosis information is acquired and recorded in the memory, and the process proceeds to step S15. In step S15, when the ignition switch is turned off (IG-OFF) (YES in step S15), the flow ends. If IG-OFF is not set (NO in step S15), the process returns to step S11 and the flow is repeated.

  Further, the telematics ECU 13 transmits the acquired and recorded driver ID and vehicle information and diagnostic information to the server device 3 via the communication module 14. Therefore, the communication module 14 corresponds to the transmission means in the claims. If the diagnosis information is not recorded, the driver ID and the vehicle information are transmitted to the server device 3. The transmission of the driver ID and the vehicle information or the diagnosis information may be performed every predetermined period such as every day, or may be performed when the ignition switch of the vehicle is turned on (IG-ON). The server apparatus 3 may be configured to perform a transmission request.

  The DLC3 connector 15 is a so-called failure diagnosis connector for connecting the scan tool 4 that collects diagnostic information from the ECU of the vehicle. The scan tool 4 is, for example, a scan tool that can be connected to a PC or a scan tool that uses the PC itself. The scan tool 4 acquires the driver ID, vehicle information, and diagnostic information recorded by the telematics ECU 13 via the DLC3 connector 15 and transmits them via a network. To the server device 3. In this case, the telematics ECU 13 corresponds to the transmission means in the claims.

  In the present embodiment, the configuration in which the telematics ECU 13 acquires and records the vehicle information and diagnostic information detected by each of the ECUs 16 to 20 when detecting the behavior of the trigger vehicle is shown. Not exclusively. For example, when the behavior of the trigger vehicle is detected, the vehicle information and diagnostic information detected by the ECUs 16 to 20 are recorded, and the vehicle information and diagnostic information recorded in the ECUs 16 to 20 are recorded in the telematics ECU 13. May be acquired and transmitted to the server device 3 via the communication module 14. In this case, the vehicle information and diagnosis information acquired from each of the ECUs 16 to 20 may be temporarily recorded in association with the driver ID of the driver who is driving the vehicle by the telematics ECU 13.

  Moreover, although the telematics ECU13 showed the structure which acquires and records the vehicle information and diagnostic information which each ECU16-20 detected in this embodiment, it does not necessarily restrict to this. For example, it is good also as a structure which acquires the vehicle information and diagnostic information detected by each ECU16-20 with the computer connected to vehicle-mounted LAN21 other than telematics ECU13, and links | couples and records the driver ID of the driver who is driving the vehicle. . In this case, the recorded driver ID, vehicle information, and diagnosis information may be acquired by the scan tool 4 via the DLC3 connector 15 and transmitted to the server device 3. In this case, the computer connected to the in-vehicle LAN 21 other than the telematics ECU 13 corresponds to the vehicle information recording means and the diagnostic information recording means.

  Further, when the behavior of the vehicle serving as the trigger is detected, the vehicle information and diagnostic information detected by each ECU 16-20 are recorded in association with the driver ID of the driver who is driving the vehicle by each ECU 16-20. The driver ID and vehicle information and diagnosis information recorded in the ECUs 16 to 20 may be acquired by the scan tool 4 via the DLC3 connector 15 and transmitted to the server device 3. In this case, the engine ECU 16, the brake ECU 17, the HV_ECU 18, the cruise ECU 19, and the EPS_ECU 20 correspond to vehicle information recording means and diagnostic information recording means. In these modified examples, the in-vehicle terminal 1 may not include the telematics ECU 13 and the communication module 14.

  Further, not only when the behavior of the vehicle serving as a trigger is detected, the vehicle information and diagnosis information detected by the ECUs 16 to 20 are sequentially recorded, and the recorded driver ID, vehicle information and diagnosis information are stored in the server device 3. It is good also as a structure which transmits.

  Returning to FIG. 1, the server device 3 is a server device of an insurance company that handles insurance for at least one of a vehicle and a vehicle driver. Here, a schematic configuration of the server apparatus 3 will be described with reference to FIG. FIG. 5 is a block diagram illustrating a schematic configuration of the server device 3. As shown in FIG. 5, the server device 3 includes a communication unit 31, a control unit 32, a fee calculation information database (DB) 33, and an individual fee DB 34.

  The communication unit 31 performs communication with the communication module 14 and the scan tool 4 of the in-vehicle terminal 1. Specifically, the communication unit 31 receives vehicle information or diagnostic information transmitted from the communication module 14 of the in-vehicle terminal 1 via the network, or a vehicle transmitted from the in-vehicle terminal 1 via the scan tool 4. Receive information and diagnostic information. Therefore, the communication unit 31 corresponds to a receiving unit in the claims. The communication part 31 is good also as a structure which transmits the transmission request of vehicle information or a diagnosis information toward the communication module 14, for example according to the instruction | indication of the control part 32. FIG.

  For example, the communication unit 31 may obtain a driver ID, vehicle information, and diagnostic information from the in-vehicle terminal 1 via an information server of a vehicle dealer, an information server of a vehicle manufacturer, or the like.

  The control unit 32 is configured as a normal computer, and includes a known CPU, a memory such as a ROM and a RAM, an I / O, and a bus line (none of which is shown) for connecting these configurations. ing. Based on various information input from the communication unit 31 and the fee calculation information DB 33, the control unit 32 performs a diagnosis process (hereinafter referred to as a driving diagnosis process) regarding the driving quality of the driver of the vehicle and a process (hereinafter referred to as insurance premium calculation). , Insurance premium calculation processing) and the like. Therefore, the control unit 32 corresponds to the driving diagnosis means and insurance premium calculation means in the claims.

  In the driving diagnosis process, for example, the driving skill of the driver is determined based on the vehicle information and the diagnosis information obtained from the in-vehicle terminal 1 (that is, whether the driving of the driver is good or not). Specifically, the vehicle information detected when the vehicle malfunction is detected is specified based on the time stamp given to the vehicle information and the time stamp given to the diagnosis information. And a driving skill is determined based on the vehicle information which excluded the vehicle information detected when the malfunction of the vehicle was detected. The determined driving skill is associated with the driver ID associated with the vehicle information used for the determination.

  The method for determining the driving skill may be a configuration using a known method. As an example, based on the vehicle information, it detects the driving that increases the risk of accidents such as sudden acceleration, sudden braking, and sudden steering (hereinafter referred to as risk driving), obtains the frequency of risk driving, and increases the frequency of risk driving. The driving skill may be determined according to the situation. The driving skill may be configured to be evaluated in a plurality of stages such as five stages according to the frequency of risk driving. The detection of risk driving may be performed in the same manner as the detection of the behavior of the vehicle serving as the trigger described above.

  Further, the frequency of risk driving may be the frequency of risk driving per hour or the frequency of risk driving per mileage. In the case of a configuration for obtaining the frequency of risk driving per hour, the time information may be a configuration using a time stamp given to the vehicle information, or a configuration using time information obtained from a timer (not shown). It is good. In the case of a configuration for obtaining the frequency of risk driving per mileage, the vehicle-mounted terminal 1 obtains information on the mileage of the vehicle from, for example, a meter ECU, and transmits it to the server device 3 together with vehicle information and diagnostic information. What is necessary is just to make it possible for the server device 3 to use information on the travel distance.

  What is necessary is just to set it as the vehicle information with which the time stamp which shows the time after the time which the time stamp which was given to the diagnostic information shows for example the time information given when the malfunction of the vehicle is detected is given. . Further, for example, the vehicle information may be a vehicle information to which a time stamp indicating a time whose error from the time is within a predetermined range after the time indicated by the time stamp given to the diagnosis information. The predetermined range here is a time range in which, for example, a malfunction of the vehicle indicated by the temporarily detected diagnosis information is likely to affect the value of the vehicle information, and can be arbitrarily set. It is a range.

  Moreover, it is good also as a structure which estimates the vehicle information which tends to produce the influence by the malfunction of the vehicle which a diagnosis information shows, excludes the estimated vehicle information, and determines a driving skill. For example, if the diagnosis information is information indicating an abnormality in the hydraulic system, information such as vehicle speed and longitudinal acceleration after the time indicated by the time stamp given to the diagnosis information is estimated as the vehicle information that is likely to have the above-described influence.
