Description

Technical Field

[0001] The present invention relates to a vehicle control system, and particularly to a vehicle control system that detects an operation of a mobile device carried by a driver during vehicle driving and controls the vehicle accordingly. Background Art

[0002] Since mobile devices such as smartphones and tablet terminals have become popular, in recent years, technologies for providing telematics services that enable in-vehicle devices mounted on vehicles to have communication functions and to link the in-vehicle devices with mobile devices to provide services have been developed.

[0003] For example, Patent Document 1 discloses the following technology: when an unauthorized authentication of an in-vehicle device of a vehicle owned by a user is performed by a third party using wireless communication, a notification of unauthorized authentication is sent to the user's mobile device.

[0004] Thus, through the development of telematics technology between vehicles and mobile devices, it is possible to confirm vehicle status, etc. using a mobile device at a location far from the vehicle, which can improve user convenience. On the other hand, the carrying rate of mobile devices during vehicle driving has also increased, resulting in the driver operating the mobile device even during driving, which may cause traffic accidents.

[0005] Although the operation of mobile devices during vehicle driving is restricted by law, in order to more reliably ensure safety, the development of a system that also suppresses the operation of mobile devices during driving on the vehicle side is underway.

[0006] For example, Patent Document 2 describes a vehicle-mounted warning device that warns when a driver operates a mobile device during vehicle driving. The warning device includes: a shift sensor that detects the gear position of the vehicle's shift lever; an infrared sensor that measures the thermal distribution inside the vehicle cabin; a camera that captures an image inside the vehicle cabin; and a speaker that warns the driver.

[0007] When the gear position is in a gear other than the parking gear and the vehicle is in motion, the warning device detects whether there is an operation of a mobile device by the driver based on the thermal distribution inside the vehicle cabin detected by the infrared sensor and the image data captured by the camera inside the vehicle cabin. When an operation of the mobile device is detected, a warning sound is generated from the speaker to warn the driver.

[0011] Patent Document 2: Japanese Unexamined Patent Application Publication No. 2018-156539 SUMMARY OF THE INVENTION

[0012] Technical Problem

[0013] However, in the above warning device, since the operation of the mobile device is indirectly detected using an infrared sensor and / or a camera, for example, when the mobile device is operated at a position in the vehicle where the sensor cannot detect, although the driver is actually operating the mobile device, the warning device cannot detect it.

[0014] The present invention has been made in view of the above problems, and an object thereof is to provide a vehicle control system that can reliably detect the operation of a mobile device during vehicle driving and ensure the safety of the vehicle when there is an operation of the mobile device in a system that communicates between the vehicle and the mobile device.

[0015] Technical Solution

[0016] In order to achieve the above object, a vehicle control system according to the present invention is characterized in that, in a vehicle control system including an in-vehicle device mounted on a vehicle and wirelessly communicating with a mobile device, the in-vehicle device includes: a drive device that generates a driving force for driving the vehicle; an authentication unit that authenticates the mobile device by wirelessly communicating with the mobile device; a determination unit that determines whether the vehicle is in a predetermined driving state; and an operation detection unit that receives a signal transmitted from the mobile device and detects an operation of the mobile device, and, when the lock of the drive device is released by the establishment of authentication based on the authentication unit, it is determined by the determination unit that the vehicle is in a predetermined driving state, and an operation of the mobile device is detected by the operation detection unit, a predetermined safety control for promoting the safety maintenance of the vehicle is executed.

[0017] According to this configuration, by authenticating the mobile device by the in-vehicle device and releasing the lock of the drive device, the in-vehicle device can identify the mobile device held by the driver when driving the vehicle. In addition, when the vehicle is in a predetermined driving state, that is, when it is determined that the vehicle is being driven, the in-vehicle device can directly detect an operation of the mobile device by receiving a signal transmitted from the mobile device, so that the operation of the mobile device during driving can be reliably detected. In addition, when there is an operation of the mobile device during driving, the safety of the vehicle can be ensured by executing a predetermined safety control.

[0018] Further, the present invention is characterized in that, in the vehicle control system, the in-vehicle device is provided with a forward safety device for assisting the safe driving of the vehicle, and if the safety control is executed, the forward safety function is executed using the forward safety device.

[0019] According to this configuration, during vehicle driving, when there is an operation of the mobile device by the driver, the forward safety function is executed by operating the forward safety device of the vehicle, thereby ensuring the safety of the vehicle.

[0020] Further, the present invention is characterized in that, in the vehicle control system, if the safety control is executed, the in-vehicle device limits the maximum value of the acceleration of the vehicle.

[0021] According to this configuration, it is possible to prevent a situation where the driver mistakenly operates the accelerator pedal of the vehicle while operating the mobile device during driving, resulting in a sudden acceleration of the vehicle. Therefore, the occurrence of accidents can be suppressed and the safety of the vehicle can be ensured.

[0022] Further, the present invention is characterized in that, in the vehicle control system, the in-vehicle device is provided with a warning device for warning the driver visually, auditorily, and / or tactilely, and if the safety control is executed, the warning device is operated to give a warning.

[0023] According to this configuration, during vehicle driving, when there is an operation of the mobile device by the driver, by warning the driver using the warning device, the operation of the mobile device can be prohibited and the safety of the vehicle can be ensured.

[0024] Further, the present invention is characterized in that, in the vehicle control system, after the in-vehicle device executes the safety control, the safety control is released after a predetermined time has elapsed.

[0025] According to this configuration, it is possible to prevent the state of executing the safety control from continuing for a long time and deteriorating the driving operability.

[0026] Technical Effects

[0027] According to the vehicle control system of the present invention, it is possible to reliably detect the operation of the mobile device during vehicle driving, and to ensure the safety of the vehicle when there is an operation of the mobile device. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 1 This is a schematic explanatory diagram of a vehicle control system as an embodiment of the present invention. Figure 2 This is a system configuration diagram of the vehicle control system. It should be noted that Figure 1 This shows the state where the driver 60 is seated in the driver's seat 62 of the vehicle 16. The vehicle control system 10 includes a mobile device 12 as a mobile device, a server device 14, and an in-vehicle device 18 mounted on the vehicle 16.

[0051] The in-vehicle device 18 includes a control unit 20, a drive device 40, an accelerator device 42, a shift device 44, a parking brake device 46, a display device 48 used as a warning device, and a forward safety device 50. The mobile device 12, the server device 14, and the in-vehicle device 18 are configured to each have a communication unit and be able to communicate with each other via long-distance communication such as the Internet and / or the telephone communication network of a mobile phone, and / or short-range wireless communication.

[0052] The mobile device 12 is configured to include a control circuit in which a microcomputer is the main body in the device main body, a display unit (for example, a liquid crystal panel) constituting a touch panel, an input operation unit, a communication unit that performs long-distance wireless communication or short-range wireless communication such as Bluetooth (registered trademark) or wireless LAN (Local Area Network), and the like. It should be noted that the mobile device used in the vehicle control system of the present invention is not limited to the mobile device 12, and can also be, for example, a communication device such as a tablet terminal, a wearable terminal, or a PDA (Personal Digital Assistant) having a touch-operable display unit and / or an input operation unit.

[0053] In addition to ordinary application software such as voice communication, the mobile device 12 is also equipped with application software (hereinafter, also referred to as operation detection application) downloaded (acquired) from the server device 14 for detecting the operation of the mobile device 12. The operation detection application is executed by the microcomputer included in the hardware of the mobile device 12.

[0054] The operation detection application detects whether the user operates the mobile device 12, and sends an operation detection signal to the in-vehicle device 18 when there is an operation. The operation detection signal can be sent to the in-vehicle device 18 via the server device 14, or can be sent without passing through the server device 14. Here, the operation of the mobile device 12 detected by the operation detection application can be set as the operation of the user on the touch panel that is the operation screen of the mobile device 12, and operations equivalent thereto. For example, the operation detection application can be configured as follows: when the user touches the touch panel of the mobile device 12, when the mobile device 12 is unlocked, when the display screen of the mobile device 12 is switched, when the user responds to a voice call and / or a video call received by the mobile device 12, etc., it is determined that there is an operation of the mobile device 12, and an operation detection signal is sent.

[0055] The server device 14 is configured to include an information processing device such as a central processing unit (CPU) and / or an application-specific integrated circuit (ASIC), a storage device such as a RAM and / or a ROM, and an input / output interface, etc. The server device 14 is installed in a company of an automobile manufacturer that manufactures the vehicle 16, or a business operator commissioned by the automobile manufacturer (hereinafter referred to as the automobile manufacturer, etc.), and is operated and managed by the automobile manufacturer, etc.

[0056] The server device 14 is configured to be able to perform wireless communication with the in-vehicle device 18 and the mobile device 12 through a communication unit assembled in the device main body, and is configured to be able to obtain information related to the vehicle 16 through the Internet line, such as the driving state of the vehicle 16, the authentication ID of the mobile device 12 registered in the in-vehicle device 18, the authentication establishment state of the in-vehicle device 18 and the mobile device 12, etc. It should be noted that in the present embodiment, although as shown by the double-headed arrow of the solid line in Figure 2 the communication between the in-vehicle device 18 and the mobile device 12 is performed via the server device 14, alternatively, it may be a configuration in which the in-vehicle device 18 and the mobile device 12 perform direct communication without passing through the server device 14 as shown by the double-headed arrow of the dotted line. In the description of the communication between the in-vehicle device 18 and the mobile device 12 described below, the description of the communication of the intermediate server device 14 is omitted.

[0057] The control unit 20 of the in-vehicle device 18 is configured to include an information processing device such as a central processing unit (CPU) and / or an application-specific integrated circuit (ASIC), a storage device such as a RAM and / or a ROM, and an input / output interface, etc. The control unit 20 is electrically connected to the drive device 40, the throttle device 42, the shift device 44, the parking brake device 46, and the display device 48 of the vehicle 16 respectively, and controls these devices. In addition, the control unit 20 executes a predetermined safety control when a predetermined condition is satisfied in the in-vehicle device 18. In the present embodiment, as the safety control, the execution of the forward safety function based on the forward safety device 50, the limitation of the acceleration of the vehicle 16, and the warning to the driver 60 by the warning device are performed. This safety control continues during a certain period of time T preset by the control unit 20. It should be noted that the time T can be set appropriately. As an example, it can be set to 10 seconds. The safety control will be described in detail later.

[0058] The drive device 40 is a device that generates a driving force for the vehicle 16 to travel, and can be composed of an engine, a motor, a battery, and / or a transmission, etc. The output torque of the drive device 40 and the gear stage in the automatic transmission are controlled by the control unit 20.

[0059] The throttle device 42 is configured to include a throttle pedal 43 operated by a driver 60, a throttle opening sensor that detects the amount of depression of the throttle pedal 43, and the like. In the manual driving mode in which the driver 60 performs a driving operation, the control unit 20 accelerates the vehicle 16 corresponding to the amount of depression of the throttle pedal 43 based on an input signal from the throttle opening sensor. That is, the output of the drive device 40 is controlled such that the acceleration increases when the amount of depression of the throttle pedal 43 is large and the acceleration decreases when the amount of depression is small.

[0060] In addition, when safety control is executed, the control unit 20 controls the output of the drive device 40 in such a manner as to further limit the maximum value of the acceleration of the operation of the throttle pedal 43 based on the throttle device 42 compared to normal driving control. For example, when safety control is performed by the control unit 20, the in-vehicle device 18 can control in such a manner as to limit the maximum value of the acceleration to one-fifth or less of the maximum value of the acceleration in normal driving control. Thus, in safety control, even if the throttle pedal 43 is depressed to the maximum, only an acceleration of one-fifth or less of the normal value can be obtained.

[0061] The shift device 44 includes a shift lever 45 operated by the driver 60. When the gear position of the shift lever 45 is input to the control unit 20, the gear position of the automatic transmission of the drive device 40 is changed accordingly. Specifically, when the gear positions of the shift lever 45 are changed to the P (parking) position, R (reverse) position, N (neutral) position, and D (drive) position, respectively, the control unit 20 changes the gear position of the automatic transmission to the parking position, reverse position, neutral position, and drive position, respectively.

[0062] The parking brake device 46 includes: a parking brake 47 (or a hand brake) provided in the vehicle compartment; and a braking mechanism that can be switched between a locked state in which a braking force is applied to the vehicle and an unlocked state in which the braking force is released according to the operation of the parking brake 47. The braking mechanism becomes a locked state in which a braking force is applied to the wheels of the vehicle 16 to stop the rotation of the wheels when the parking brake 47 is in the open state, and becomes an unlocked state in which the braking force on the wheels is released when the parking brake 47 is in the closed state. The control unit 20 detects whether the parking brake 47 is in the open state or the closed state based on a signal input from the parking brake 47.

[0063] The display device 48 is a device that provides visual information to the driver 60 and is used as a warning device that gives a visual warning to the driver in the vehicle control system 10.

[0064] In the present embodiment, an instrument display unit that displays various types of information related to the vehicle 16 is used as the display device 48. In the in-vehicle control system 10 of the present embodiment, the following structure is also adopted: when safety control is executed, a warning sound is generated by using a speaker 49 mounted on the vehicle 16, thereby giving an auditory warning. The display device 48 and the speaker 49 are connected to the control unit 20, and the driver 60 is warned when the control unit 20 executes safety control.

[0065] The forward safety device 50 is a device that acquires information related to the vehicle 16 and information related to the external environment of the vehicle 16 and transmits the same to the control unit 20, and causes the control unit 20 to execute a forward safety function for assisting the safe driving of the vehicle 16 based on the collected information and / or recognition result. The forward safety device 50 can be constituted by, for example, a camera capable of photographing the outside of the vehicle, various sensors, and other information recognition devices, and the forward safety function can be switched between on / off by manually operating a switch 51 provided in the vehicle compartment.

[0066] In addition, in the present embodiment, it is configured such that it is possible to switch, using a driving mode switching switch provided in the vehicle compartment, between a manual driving mode in which the driver 60 drives the vehicle 16 by manual operation and an autonomous driving mode in which the vehicle 16 is automatically driven by the control unit 20 without the operation of the driver 60, and in the autonomous driving mode, the forward safety function is in an on state. When the forward safety function is turned on, control for assisting the safe driving of the vehicle 16, such as automatic braking control for recognizing an obstacle outside the vehicle and automatically stopping the vehicle 16, constant speed cruise control for causing the vehicle 16 to travel at a constant speed, and adaptive cruise control having an inter-vehicle control function, can be executed based on the information acquired by the forward safety device 50.

[0067] Next, the control unit 20 of the in-vehicle device 19 will be described in detail. The control unit 20 includes a communication unit 21, an authentication unit 22, a determination unit 23, and an operation detection unit 24.

[0068] The communication unit 21 performs information communication between the mobile device 12 and the server device 14 and constitutes a telematics system.

[0069] The authentication unit 22 authenticates the mobile device 12 based on the authentication ID transmitted from the mobile device 12 via the communication unit 21. As an authentication method, for example, the authentication ID can be transmitted from the mobile device 12 to the control unit 20 of the in-vehicle device 18 through short-range wireless communication, and it is determined whether the authentication ID received by the authentication unit 22 is consistent with the authentication ID pre-registered in the control unit 20. If they are consistent, the authentication is established, and if they are inconsistent, the authentication fails. The result of authentication success / failure can be transmitted to the mobile device 12 via the communication unit 21, and the mobile device 12 can display the received authentication result on the display unit of the mobile device 12.

[0070] If the authentication between the control unit 20 and the mobile device 12 is successful, the authentication unit 22 releases the lock of the drive device 40 of the vehicle 16. In the present embodiment, in the state where the authentication is successful and the lock of the drive device 40 is released, the drive device 40 is started by turning on the ignition switch.

[0071] It should be noted that in the vehicle control system 10 of the present embodiment, even if the authentication of the electronic key that the user of the vehicle 16 can carry is used instead of the authentication of the mobile device 12, the drive device 40 of the vehicle 16 can be started. In the process of starting the in-vehicle device 18 using the electronic key, first, wireless communication is performed between the electronic key and the in-vehicle device 18. When the ID code of the electronic key is consistent with the ID code pre-registered in the control unit 20 of the in-vehicle device 18, the control unit 20 releases the lock of the drive device 40 and turns on the ignition switch to start the drive device 40. Thus, in the vehicle control system 10 of the present embodiment, the drive device 40 can be started by using either the mobile device 12 or the electronic key, enabling the vehicle 16 to travel.

[0072] The determination unit 23 determines whether the vehicle 16 is in a predetermined driving state based on the position of the shift lever 45 of the shift device 44 and the on / off state of the parking brake 47 of the parking brake device 46. Specifically, when it is detected based on the input signals from the shift device 44 and the parking brake device 46 that at least one of the shift lever 45 is in the parking gear and the parking brake is on, it is determined that the vehicle 16 is not in the predetermined driving state, that is, it is determined that the vehicle 16 is in a stopped state and not in driving. In addition, when the shift lever 45 is in a gear other than the parking gear and the parking brake is off, it is determined that the vehicle 16 is in the predetermined driving state, that is, it is determined that the vehicle is in driving.

[0073] The operation detection unit 24 detects an operation detection signal transmitted from the mobile device 12, thereby detecting whether there is an operation of the mobile device 12. In the present embodiment, when the authentication of the mobile device 12 is established by the authentication unit 22, the lock of the drive device 40 is released by the established authentication, and the determination unit 23 determines that the vehicle 16 is in the driving state, the operation detection unit 24 is in the operation detection mode and is in a state capable of receiving the operation detection signal from the mobile device 12. If the operation detection unit 24 receives an operation detection signal transmitted from the mobile device 12 in the operation detection mode, it determines that there is an operation of the mobile device 12, and if it does not receive an operation detection signal transmitted from the mobile device 12, it determines that there is no operation of the mobile device 12.

[0074] Next, with reference to Figure 3A and Figure 3B 's process, the operation of the control unit 20 of the vehicle control system 10 described above will be described.

[0075] First, the control unit 20 determines whether the authentication of the mobile device 12 by the authentication unit 22 is established, releases the lock of the drive device 40 by the established authentication, and turns on the ignition switch to make the drive device 40 in the starting state (step S11). When the drive device 40 is started by authenticating the electronic key without authenticating the mobile device 12 (step S11: No), the operation detection mode of the operation detection unit 24 is set to the release state (that is, a state where no operation detection signal is received from the mobile device 12) (step S12), and the operation returns.

[0076] In step S11, when the authentication of the mobile device 12 is established and the lock of the drive device 40 is released, and the drive device 40 becomes in the starting state by turning on the ignition switch (step S11: Yes), the operation detection unit 24 is set to the operation detection mode, and the detection of whether there is an operation of the mobile device 12 is started (step S13). Thereafter, the control unit 20 determines whether the position of the shift lever 45 is in the parking gear based on the input signal from the shift device 44 (step S14).

[0077] In step S14, when the shift lever 45 is in the parking gear (step S14: Yes), the operation detection mode of the operation detection unit 24 is released (step S12), and the operation returns. When the shift lever 45 is in a gear other than the parking gear (step S14: No), it is determined whether the parking brake 47 is in the on state based on the input signal from the parking brake device 46 (step S15).

[0078] In step S15, when the parking brake 47 is in the ON state (step S15: YES), the operation detection mode of the operation detection unit 24 is released (step S12), and the operation returns. When the parking brake 47 is in the OFF state (step S15: NO), the control unit 20 determines whether the driving mode of the vehicle 16 has become the autonomous driving mode (step S16).

[0079] In step S16, when in the autonomous driving mode (step S16: YES), the operation detection mode of the operation detection unit 24 is released (step S12), and the operation returns. When the driving mode of the vehicle 16 changes to the manual driving mode (step S16: NO), it is determined whether the operation detection unit 24 has changed to the operation detection mode or whether the operation detection mode is in the release process (step S17). If it is in the release process, after being set to the operation detection mode (step S18), the process proceeds to the next step S19. If it is in the operation detection mode, it directly proceeds to step S19.

[0080] In step S19, it is determined whether the operation detection unit 24 has received an operation detection signal sent from the mobile device 12. When the operation detection unit 24 has received the operation detection signal, it is determined that there is an operation of the mobile device 12 (step S19: YES), the control unit 20 starts counting the time T for continuous safety control (step S20), and performs safety control. That is, the control unit 20 operates the display device 48 and the speaker 49 as warning devices to warn the driver 60 (step S21), turns on the acceleration limit function in the throttle device 42 to limit the maximum value of the acceleration (step S22), and operates the forward safety device 50 of the in-vehicle device 18 to turn on the forward safety function of the vehicle 16 (step S23), and returns the process.

[0081] If, after performing safety control and returning the process, an operation of the mobile device 12 is detected again during the continuous process of safety control (step S19: YES), the timer of the control unit 20 is reset to zero (step S20), and the safety control continues for a period of time T starting from the newly detected operation of the mobile device 12.

[0082] On the other hand, in step S19, when the operation detection unit 24 has not received an operation detection signal from the mobile device 12 (step S19: NO), the control unit 20 determines whether the time counted by the timer is equal to or greater than the time T (step S24). If it is not equal to or greater than the time T, the process returns. In step S24, when the counted time has passed the time T, the acceleration limit function of the throttle device 42 is turned off, and the process returns to the normal control without limiting the maximum value of the acceleration (step S25). Furthermore, the forward safety function of the forward safety device 50 is turned off, and the vehicle 16 returns to the manual driving mode, and the process returns.

[0083] As described above, in the vehicle control system 10 of the present embodiment, the locking of the drive device 40 is released and it is started by authenticating the mobile device 12 in the in-vehicle device 18 that communicates with the mobile device 12. Thus, when driving the vehicle 16, the in-vehicle device 18 can recognize the mobile device 12 held by the driver 60. In addition, after the authentication of the mobile device 12 is established, the in-vehicle device 18 sets the vehicle 16 to a predetermined driving state. That is, when the gear position of the shift device 44 of the vehicle 16 is not in the parking position and the parking brake is in the off state, and it is determined that the vehicle is in the driving state, by setting the operation detection unit 24 to the operation detection mode and receiving the operation detection signal transmitted from the mobile device 12, it is possible to directly detect whether there is an operation of the mobile device 12. Therefore, it is possible to reliably detect the operation of the mobile device 12 during driving.

[0084] In addition, when there is an operation of the mobile device 12 during driving, by causing the in-vehicle device 18 to execute safety control, the safety of the vehicle 16 can be ensured. In the present embodiment, by using the safety control, the forward safety device 50 is forced to operate to turn on the forward safety function, so that the safe driving of the vehicle 16 can be assisted by automatic braking control and / or adaptive cruise control, etc. In addition, when the safety control is executed, by warning the driver 60 by the display device 48 and the speaker 49, the operation of the mobile device 12 can be prohibited to ensure the safety of the vehicle. It should be noted that the warning can be configured to use only one of the display device 48 and the speaker 49.

[0085] In addition, by using the safety control to turn on the acceleration limit function, it is possible to prevent the situation where the vehicle 16 accelerates sharply due to the incorrect operation of the accelerator pedal 43 during driving. Therefore, the occurrence of accidents can be suppressed and the safety of the vehicle can be ensured. It should be noted that although the control unit 20 can also make the vehicle 16 unable to accelerate when the acceleration limit function is turned on, in the present embodiment, the maximum value of the acceleration during the limit is greater than zero. Thus, when the driver 60 wants to accelerate the vehicle 16 during the safety control, while preventing a sharp acceleration, the vehicle 16 is allowed to accelerate slowly.

[0086] In addition, in the vehicle control system 10 of the present embodiment, after the safety control is executed and a predetermined time T has elapsed, the safety control is automatically released. Therefore, it is possible to prevent the safety control from being continuously performed for a long time and deteriorating the driving operability of the driver 60.

[0087] It should be noted that the release of the safety control can be configured as follows: instead of automatic release based on the passage of time T, a switch for releasing the safety control is provided inside the vehicle compartment, and the driver 60 operates this switch to perform manual release. In addition, the release of the safety control can also be configured as follows: automatic release and manual release are used in combination, and in the case of switch operation, the safety control can be released even without the passage of time T.

[0088] It should be noted that the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the gist of the invention.

[0089] For example, in the present embodiment, although three controls, namely the operation of the forward safety function, the limitation of acceleration, and the warning based on the warning device, are executed as the safety control performed by the control unit 20, it is sufficient to execute at least one of these controls.
