Description

  The present invention relates to a vehicle control device, and more particularly, to a vehicle control device that performs vehicle control using a speed limit set for a travel path.

  In recent years, various driving support modes have been provided to drivers by driving support control devices mounted on vehicles. For example, there is known a driving support mode in which vehicle control is performed so that a preceding vehicle is followed with a preset vehicle speed set as an upper limit speed (see Patent Document 1). Further, in Patent Document 1, a speed limit (marking speed) is detected from a speed sign imaged by a camera, and after a predetermined time (3 seconds), the set vehicle speed is replaced by the detected speed limit. Thus, in Patent Document 1, when a speed sign is detected, this speed limit (mark speed) is used as the set vehicle speed.

  The driver can disable the set speed from switching to the sign speed by operating a resume switch provided on the steering wheel within a predetermined time. In general, the resume switch is a switch for switching the driving support mode from the standby state to the active state. When the set speed is stored in the memory, the driving support mode is resumed using this set speed by operating the resume switch.

  Hereinafter, a vehicle control apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings. First, with reference to FIG.1 and FIG.2, the structure of a vehicle control apparatus is demonstrated. FIG. 1 is a configuration diagram of the vehicle control device, and FIG. 2 is an explanatory diagram of an operation unit.

  The vehicle control device 100 of the present embodiment is mounted on the vehicle 1 (see FIG. 3), and is configured to execute predetermined driving support control according to the driving support mode selected by the driver. .

  In the present embodiment, the driving support mode includes a preceding vehicle following mode and a speed limit mode. The preceding vehicle follow-up mode is a mode in which vehicle control is performed so that the vehicle travels to maintain the set vehicle speed when there is no preceding vehicle, and follows the preceding vehicle with the set vehicle speed as the upper limit when there is a preceding vehicle. Then, speed control and steering control of the vehicle 1 are executed. In this speed control, the vehicle control device 100 automatically controls the engine output via the engine control system 40 and automatically controls the braking force via the brake control system 42. In the steering control, the vehicle control device 100 automatically controls the steering angle by the steering wheel via the steering control system.

  The speed limit mode is a mode for executing vehicle control (speed control) so that the speed of the vehicle 1 does not exceed the set vehicle speed. In this mode, when the driver operates the accelerator pedal, the engine output is controlled according to the depression amount of the accelerator pedal. However, when the speed of the vehicle 1 exceeds the set speed, the vehicle control device 100 limits the speed of the vehicle 1 to the set speed regardless of the amount of depression of the accelerator pedal. In this case, the vehicle control device 100 restricts the engine output via the engine control system 40 and applies a braking force via the brake control system 42 as necessary.

  As shown in FIG. 1, the vehicle control apparatus 100 includes a control unit (ECU) 10, various sensors / input / output units, and a predetermined vehicle system. In the sensor / input / output unit, a camera 20 for imaging outside the vehicle, a radar device 22 for detecting other vehicles in front of and behind the vehicle, a vehicle speed sensor 23 for detecting the speed of the vehicle 1, and user input for driving support control. An operation unit 24, a navigation device 26, a display unit 28 for presenting information to the driver, a speaker 29, other sensors, and the like are included. The vehicle system includes an engine control system 40 and a brake control system 42.

  The ECU 10 includes a CPU, a memory 11 that stores various programs and data, and a computer that includes an input / output device. The ECU 10 includes various functions, for example, functions as a control unit 10a and a speed limit recognition unit 10b.

  The ECU 10 (control unit 10a) displays predetermined information on the display unit 28 based on a signal received from the outside during the operation of the driving support mode, and a vehicle system (engine control system 40, brake control system 42, etc.). ) To output a request signal and execute a vehicle control process. Further, the data stored in the memory 11 includes a set speed used for speed control during execution of the driving support mode and the speed limit acquired by the speed limit recognition unit 10b.

  The ECU 10 (control unit 10a) monitors the current vehicle speed of the vehicle 1 detected by the vehicle speed sensor 23, and when the current vehicle speed exceeds the threshold speed, an overspeed alarm is generated from the speaker 29 (notification unit). Execute alarm processing. In addition to the speaker 29, an overspeed warning may be displayed on a display included in the navigation device 26, the display unit 28, or the like.

  The ECU 10 (restricted speed recognizing unit 10b) performs a speed limit recognizing process for acquiring a speed limit (signed speed) indicated by a speed sign in the image by analyzing the image data captured by the camera 20. . The camera 20 images the front of the vehicle 1 and transmits the captured image data to the ECU 10. The speed limit recognition unit 10b may include the camera 20 as a component.

  The radar 22 transmits radio waves (transmitted waves) toward the front and rear of the vehicle 1 and receives the reflected waves. Based on the transmitted wave and the reflected wave, the radar 22 obtains measurement data related to the inter-vehicle distance between the other vehicle and the vehicle 1 existing in front and rear of the vehicle 1 and measurement data related to the relative speed of the other vehicle. Output signal including. A sensor such as a laser radar or sonar may be used instead of the radar 22 and / or instead of the radar 22.

  The operation unit 24 is provided on the steering wheel of the vehicle 1 and includes a plurality of switches. As shown in FIG. 2, the operation unit 24 includes on switches 24a and 24b that are start switches in the driving support mode, an off switch 24c that is a stop switch, a cancel switch 24d, speed setting switches 24e and 24f, and a resume (resume) switch. 24g.

  The preceding vehicle following mode is activated by the operation (pressing) of the on switch 24a. Further, the speed limit mode is activated by operating the on switch 24b. The operating state of each driving support mode includes an active state and a standby state. In the active state, control (speed control) for changing the vehicle behavior is executed via the engine control system 40 and the brake control system 42. The standby state is a state in which the vehicle behavior change control is temporarily disabled.

By operating the off switch 24c, the currently operating driving support mode is stopped regardless of the active state or the standby state. During operation of the driving support mode, the set speed stored in the memory 11 of the ECU 10 is used, but the set speed stored in the memory 11 is cleared (erased) by operating the off switch 24c.
By operating the cancel switch 24d, the driving support mode is switched from the active state to the standby state.

  The set speed can be increased from the current value by operating the speed setting switch 24e. Further, the set speed can be reduced from the current value by operating the speed setting switch 24f. When the set speed is input by the driver, the set speed is stored in the memory 11 of the ECU 10. For example, the driver can input the current vehicle speed of the vehicle 1 as the set speed by pressing one of the speed setting switches 24e and 24f after pressing the on switches 24a and 24b. Furthermore, the set speed can be increased or decreased by operating the speed setting switches 24e and 24f with the set speed stored in the memory 11.

  As a basic operation function, the resume switch 24g is operated when the driving support mode is in the standby state, so that the driving support mode in operation is set using the set speed stored in the memory 11 of the ECU 10. Used to resume (active state).

  The navigation device 26 can acquire the current position of the vehicle 1 using GPS or the like, and can specify the position of the vehicle 1 on the map based on the stored map information or map information of an external source. Moreover, the navigation apparatus 26 can also acquire the speed limit (marking speed) of the travel path on which the vehicle 1 is traveling from the current position on the map. Therefore, the navigation device 26 may be used as the speed limit recognition unit.

  The display unit 28 is arranged on an instrument panel or the like, and includes an operation status display field 28a, a set speed display field 28b, and a speed limit display field 28c (see FIG. 4). In FIG. 4, only one operation status display column 28a is displayed for easy understanding, but an operation status display column can be provided corresponding to each of a plurality of driving support modes.

The operation status display column 28a indicates the operation status in the driving support mode. In the operation status display field 28a, the execution state of the driving support mode is displayed as “blank (off)”, “active”, or “standby”.
The set speed display field 28b displays a set speed (for example, “80”) stored in the memory 11 of the ECU 10. If the set speed is not stored in the memory 11, “blank (---)” is displayed in the set speed display field 28b.
The speed limit display field 28c displays the acquired speed limit (for example, “50”). When the speed limit is not acquired, “blank” is displayed in the speed limit display field 28c.

  Next, various operations of the operation unit according to the present embodiment will be described with reference to FIGS. 3 is an explanatory diagram when the speed limit is acquired, FIG. 4 is an explanatory diagram when the resume switch is operated (standby state; with memory storage), and FIG. 5 is an explanatory diagram when the resume switch is operated (standby state; no memory storage). 6 is an explanatory diagram when the resume switch is operated (active state), and FIG. 7 is an explanatory diagram when the cancel switch is operated.

  FIG. 3 shows a situation where the vehicle 1 is traveling at a speed of 80 km / h (V = 80) on the travel path 3 having a speed limit of 80 km / h. The vehicle 1 detects a speed sign 5 (limited speed “50 km / h”) installed near the travel path 3 at a position A before the speed sign 5. Thereafter, the vehicle 1 passes by the side of the speed sign 5 (position B) and enters the section where the speed limit is 50 km / h (position C). In addition, the preceding vehicle follow-up mode or the speed limit mode is selected as the driving support mode. In the speed control in the preceding vehicle following mode, the vehicle 1 is automatically accelerated or decelerated. On the other hand, in the speed control in the speed limit mode, only automatic deceleration of the vehicle 1 is executed, and the driver can increase the speed of the vehicle 1 by operating the accelerator pedal.

  In the example of FIG. 4, the position A is displayed on the display unit 28 of the vehicle 1 as shown in FIG. At this time, the driving support mode is in a standby state (“standby”), and the set speed is 80 km / h (“80 km / h”). Further, since the speed indicator 5 is detected, the speed limit is 50 km / h (“50”).

  When the driver operates (presses) the resume switch 24g at the position B, the operation function of the resume switch 24g (similar to the prior art) is executed. That is, as shown in FIG. 4B, the operation state of the driving support mode is switched from the standby state to the active state while the set speed is maintained at 80 km / h. Accordingly, “active” is displayed in the operation status display field 28a (position C). The vehicle control device 100 executes speed control via the engine system 40 and the brake system 42 with the set speed as a target speed. In this case, the speed of the vehicle 1 is reduced from 80 km / h to 50 km / h. As described above, since the conventional operation function of the resume switch has not changed, the driver can perform the same operation as before without erroneous operation.

  In the example of FIG. 5, at the position A, it is displayed on the display unit 28 of the vehicle 1 as shown in FIG. At this time, the driving support mode is in a standby state (“standby”), and the speed limit is 50 km / h (“50”). However, the set speed is not stored in the memory 11, and a blank ("---") is displayed in the set speed display field 28b.

  When the driver operates (presses) the resume switch 24g at the position B, as shown in FIG. 5B, the set speed is replaced by the speed limit (50 km / h), and the set speed display field 28b displays “50”. "(50 km / h) is displayed (position C). That is, the driver can set the speed limit as the set speed by operating the resume switch 24g when the set speed is not stored in the memory 11 in the standby state. However, the operating state of the driving support mode is maintained in the standby state. When the driver wants to activate the driving support mode, as described with reference to FIG. 4, the driver may operate the resume switch 24g again.

  Conventionally, even when the resume switch is operated in the situation shown in FIG. However, in the present embodiment, the driver can easily input the speed limit to the set speed by operating the resume switch 24g. Therefore, it is not necessary to operate the speed setting switches 24e and 24f as in the prior art, and the operation can be simplified.

  In the example of FIG. 6, at the position A, the display unit 28 of the vehicle 1 is displayed as shown in FIG. At this time, the driving support mode is in an active state (“active”), the set speed is 80 km / h (“80 km / h”), and the speed limit is 50 km / h (“50”).

  When the driver operates (presses) the resume switch 24g at the position B, as shown in FIG. 6B, the set speed is replaced with the speed limit (50 km / h), and the set speed display field 28b displays “50 km. / H "is displayed (position C). That is, the driver can set the speed limit as the set speed by operating the resume switch 24g in the active state. The vehicle control device 100 executes speed control via the engine system 40 and the brake system 42 using the newly set speed as a target speed. In this case, the speed of the vehicle 1 is reduced from 80 km / h to 50 km / h.

  In this way, the resume switch 24g has another operation function (switching the operating state of the driving support mode from the standby state to the active state using the set speed displayed in the set speed display field 28b), Also serves as an operation function (rewrites the set speed with the speed limit in the active state). As a result, the driver can easily operate using the existing resume switch 24g without providing an additional switch in the operation unit 28.

  In the example of FIG. 7, at the position A, the display unit 28 of the vehicle 1 is displayed as shown in FIG. At this time, the driving support mode is in an active state (“active”), the set speed is 80 km / h (“80 km / h”), and the speed limit is 50 km / h (“50”).

  When the driver operates (depresses) the cancel switch 24d at the position B, as shown in FIG. 7B, the driving support mode is switched from the active state to the standby state. Is displayed (position C). Furthermore, in the present embodiment, the set speed is replaced with the speed limit (50 km / h), and “50” (50 km / h) is displayed in the set speed display field 28 b. The vehicle control device 100 does not execute speed control because the driving support mode is switched to the standby state. In this case, the driver operates the brake pedal or uses the engine brake, for example, to decelerate the vehicle 1 from 80 km / h to 50 km / h.

  Thus, in addition to the conventional operation function (switching the operation state of the driving support mode from the active state to the standby state), the cancel switch 24d also functions as another operation function (rewriting the set speed with the speed limit). Thereby, when the driving support mode is resumed, the set speed is already set to the speed limit, so that the driver does not need to input the set speed again when the driving support mode is resumed.

Next, the flow of the vehicle control process in the driving support mode according to the present embodiment will be described with reference to FIGS. 8 and 9 are flowcharts of the vehicle control process.
ECU10 (control part 10a) repeatedly performs the processing flow of FIG.8 and FIG.9 for every predetermined time. The ECU 10 (restricted speed recognizing unit 10b) executes a restricted speed recognizing process by another process and stores the restricted speed in the memory 11.

  First, when the process is started, the ECU 10 determines whether or not a speed limit (marking speed) has been acquired (S10). When the speed limit is not stored in the memory 11 (S10; No), the ECU 10 executes a normal process that does not use the speed limit (S11), and ends the process. On the other hand, when the speed limit is stored in the memory 11 (S10; Yes), the ECU 10 determines whether the selected driving support mode is an active state or a standby state (S12).

  When the driving support mode is in the active state (S12; Yes), the ECU 10 determines whether or not the cancel switch 24d is operated (S13). When the cancel switch 24d is operated (S13; Yes), the ECU 10 switches the driving support mode from the active state to the standby state (S14), rewrites the set speed in the memory 11 with the speed limit (S15), and ends the process. To do. Steps S12 to S15 correspond to the example of FIG.

  On the other hand, when the cancel switch 24d is not operated (S13; No), the ECU 10 determines whether or not the resume switch 24g is operated (S16). When the resume switch 24g is operated (S16; Yes), the ECU 10 determines whether or not the automatic stop is being performed (S17).

  The automatic stop is a state where the vehicle 1 is also stopped because the preceding vehicle ahead of the vehicle 1 is stopped in the preceding vehicle following mode. During the automatic stop, the ECU 10 outputs a request signal to the engine control system 40 and the brake control system 42 of the vehicle 1 so as to maintain the vehicle 1 in a stopped state.

  When the resume switch 24g is operated in a state where the driving support mode is active and not automatically stopped (S17; No), the ECU 10 rewrites the set speed in the memory 11 with the speed limit (S19), and performs processing. finish. Steps S12 to S19 correspond to the example of FIG.

  On the other hand, when the driving support mode is in the active state and the resume switch 24g is operated during the automatic stop (S17; Yes), the ECU 10 cancels the stop state of the vehicle 1 and permits the start (S18). The process is terminated. At this time, the ECU 10 outputs a request signal for following the preceding vehicle to the engine control system 40 (and the brake control system 42) instead of the request signal for maintaining the stopped state. As a result, the driving support mode (preceding vehicle follow-up control) is resumed.

  When the preceding vehicle that has been stopped starts during the automatic stop, the vehicle 1 may be started so as to automatically follow the preceding vehicle. However, in the present embodiment, in order to increase safety, the vehicle 1 is started in a state where the driver of the vehicle 1 recognizes the start of the preceding vehicle during the automatic stop (that is, the operation of the resume switch 24g).

  On the other hand, when the driving support mode is in the standby state (S12; No), the ECU 10 determines whether or not the set speed is stored in the memory 11 (S20), and when the set speed is stored (S20; Yes). ), It is determined whether or not the resume switch 24g has been operated (S21). When the resume switch 24g is operated while the driving support mode is in the standby state and the set speed is stored in the memory 11 (S21; Yes), the ECU 10 determines the set speed stored in the memory 11. While maintaining, the driving support mode is switched from the standby state to the active state (S22), and the process ends. Steps S12 to S22 correspond to the example of FIG.

  When the resume switch 24g is not operated (S21; No), the ECU 10 rewrites the set speed to the speed limit by the operation (S13) of the cancel switch 24d (S15), and then the predetermined time (for example, 3 to 3). It is determined whether or not (10 seconds) has elapsed (S23). If it is within the predetermined time (S23; Yes), the ECU 10 determines whether or not the speed setting switch 24e or 24f has been operated (S24).

  When one of the speed setting switches is operated within a predetermined time from the operation of the cancel switch 24d (S24; Yes), the ECU 10 stands by in the driving support mode as in the case where the resume switch 24g is operated (S21). The state is switched from the active state to the active state (S22), and the process ends.

  In the present embodiment, when the driving support mode is once switched to the standby state by the cancel switch 24d and then returned to the active state, the driver may operate the resume switch 24g. At the time of return, the driving support mode can be resumed with the speed limit set as the set speed. In the present embodiment, the speed setting switches 24e and 24f can be used to return the driving support mode to the active state in addition to the resume switch 24g within a predetermined time.

  On the other hand, when the predetermined time has elapsed (S23; No), the speed setting switches 24e and 24f are used for normal operation functions. That is, when the speed setting switch 24e or 24f is operated (S25; Yes), the ECU 10 changes the set speed stored in the memory 11 according to the operation of the speed setting switch 24e or 24f (S26), and performs the process. finish.

  On the other hand, when the set speed is not stored in the memory 11 (S20; No), the ECU 10 determines whether or not the resume switch 24g is operated (S28). When the resume switch 24g is operated when the driving support mode is in the standby state and the set speed is not stored in the memory 11 (S28; Yes), the ECU 10 rewrites the set speed in the memory 11 with the speed limit. (S29), the process ends. At this time, the driving support mode is maintained in the standby state. Steps S12 to S29 correspond to the example of FIG.

Next, the operation of the driving support control device of this embodiment will be described.
The vehicle control apparatus 100 according to the present embodiment includes a control unit (ECU 10) that performs speed control of the vehicle 1 according to a stored set vehicle speed during execution of the driving support mode, and an operation unit that can be operated by the driver. 24 and a speed limit recognition unit (ECU 10, navigation device 26) for acquiring a speed limit for the travel path 3, and the driving support mode is in an active state in which the speed control is executed and the speed control is temporarily disabled.

  Thus, in this embodiment, the driver can switch the driving assistance mode from the active state to the standby state by operating the cancel switch 24d. At this time, in the present embodiment, the speed limit for the travel path 3 is stored as the set speed. Thereby, in this embodiment, when the driving assistance mode returns to the active state again, the speed control by the driving assistance mode is executed with the speed limit of the travel path 3 as the set speed. For this reason, when returning to the active state, the driver does not need to reset the set speed in accordance with the travel path 3, and the operability by the driver can be improved along with safety.

Until a predetermined time (for example, 3 to 10 seconds) elapses (S23; Yes), the driving support mode is switched from the standby state to the active state in response to the operation (S24) of the speed setting switches 24e and 24f. (S22).

  As described above, in the present embodiment, until the predetermined time elapses after the driving support mode is switched from the active state to the standby state (or after the speed limit is stored as the set vehicle speed) by the operation of the cancel switch 24d. The speed setting switches 24e and 24f can be used not for setting the set vehicle speed but for returning the driving support mode to the active state in the same manner as the resume switch 24g.

  In the present embodiment, the control unit (ECU 10), after a predetermined time has elapsed (S23; No), responds to the operation of the speed setting switches 24e and 24f (S25) and stores the stored set vehicle speed. Change (S26). Thus, in the present embodiment, the speed setting switches 24e and 24f can be used for the original function of setting the set vehicle speed after a predetermined time has elapsed.

  In the present embodiment, the operation unit 24 includes a resume switch 24g, and the control unit (ECU10) is in a standby state and the control unit (ECU10) stores the set vehicle speed (S20; Yes). In response to the resume switch operation (S21), the driving support mode is switched from the standby state to the active state (S22). Thus, in the present embodiment, the resume switch 24g can be used for switching the driving support mode from the standby state to the active state.

  In the present embodiment, the driving support mode includes a preceding vehicle follow-up mode in which the set vehicle speed is set as the upper limit speed of the vehicle 1 to follow the preceding vehicle, and a speed limit mode in which the speed of the vehicle 1 is prevented from exceeding the set vehicle speed. ,including.
