Description

  The present invention relates to a steering assistance device.

  Conventionally, as a technique in such a field, for example, a control stick described in JP-A-10-264894 has been known. With this control stick, when an aircraft or the like approaches a dangerous state such as a stall, by applying vibration in the axial direction of the control stick, the driver can be in a dangerous state without affecting the operation of the control stick by the driver. It is supposed to be able to inform.

Japanese Patent Laid-Open No. 10-264894

  However, the control stick described above has a problem that the driver may not be aware of the vibration applied to the control stick when the aircraft itself vibrates due to external factors such as turbulence.

  In the present invention, when it is determined that the operation of the control unit by the driver is not appropriate, the operation is not appropriate by adjusting the operation reaction force applied to the control unit so that the operation becomes less appropriate. An object of the present invention is to provide a steering support device that can reliably notify the driver of the vehicle.

  The present invention relates to a steering support device that supports a driver's operation of a control unit of a moving body, and includes a determination unit that determines whether or not a driver's operation of the control unit is appropriate, and a driver's control unit And a reaction force adjusting means for adjusting an operation reaction force applied to the control unit so that the operation becomes more inappropriate when it is determined that the operation is not appropriate.

  According to the steering support apparatus according to the present invention, for example, in an aircraft, when it is determined that the operation of the control unit by the driver is an improper operation that may cause a stalled state, the operation of the driver is more Adjustments such as lightening the reaction force are performed so that the operation approaches the stalled state. As a result, the operating unit that is being operated moves beyond the driver's expectation, so that the driver can be reliably notified that the operation is not appropriate.

  In addition, when it is determined that the operation of the control unit by the driver is not appropriate, the control unit further includes an operation input invalidating unit that invalidates the driver's operation input to the control unit, and the reaction force adjusting unit It is preferable to adjust the operation reaction force applied to the control unit in a disabled state.

  According to this steering support device, the operation reaction force applied to the control unit is adjusted in a state in which the driver's operation input to the control unit is invalidated. Even if the operation state becomes less appropriate, it is possible to avoid the movement being reflected in the movement of the moving body.

  Further, it is preferable that the reaction force adjusting means reduces an operation reaction force with respect to an inappropriate operation. For example, in an aircraft, by reducing the operating reaction force to an inappropriate operation that causes a stalled state, the operating part that is being operated moves in a direction that causes the vehicle to stall, exceeding the driver's expectation. The driver can be surely notified of the absence.

  Moreover, it is preferable that a moving body is an aircraft. In this case, safety in the operation of the aircraft can be improved.

  Alternatively, the moving body is preferably a vehicle that travels on the ground. In this case, safety in driving the vehicle is improved.

  According to the present invention, it is possible to reliably notify the driver that the operation is not appropriate.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a steering assistance device according to the invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same part and the overlapping description is abbreviate | omitted.

(First embodiment)
As shown in FIG. 1, a steering assistance device 1 according to the first embodiment is provided in an aircraft (moving body) and assists a driver in operating an aircraft yoke (pilot unit) 3. The steering assist device 1 includes an aircraft behavior detection unit 2, a yoke 3, a yoke operation detection unit 4, a control line connection unit 5, and an elevator (elevator) 6. Further, the steering assist device 1 includes an elevator drive detection unit 7, an input side actuator 8, an output side actuator 9, an aircraft control ECU [Electric Control Unit] (determination unit, reaction force adjustment unit) 10, a control line connection unit control ECU ( Operation input invalidating means) 11 and a warning unit 12 are provided.

  The aircraft control ECU 10 is an electronic circuit configured by a CPU [Central Processing Unit] that performs arithmetic processing, a ROM [Read Only Memory] and a RAM [Random Access Memory] that are storage units, an input signal circuit, an output signal circuit, a power supply circuit, and the like. Control unit. The aircraft control ECU 10 is electrically connected to the aircraft behavior detection unit 2, the input side actuator 8, and the output side actuator 9. Further, the aircraft control ECU 10 is electrically connected to the control line connection unit control ECU 11, the warning unit 12, and the connection switching unit 15.

  The control line connection control ECU 11 is an electronic control unit having the same configuration as the aircraft control ECU 10. The control line connection control ECU 11 is electrically connected to the yoke operation detection unit 4, the elevator drive detection unit 7, and the connection switching unit 15.

  The aircraft behavior detection unit 2 includes, for example, a speed sensor that detects the speed of the aircraft, a gyro sensor that detects the inclination of the aircraft, and the like, and detects the behavior (flight state) of the aircraft. The aircraft behavior detection unit 2 outputs the detected aircraft behavior to the aircraft control ECU 10 as aircraft behavior information.

  The yoke 3 is provided in the cockpit of the aircraft, and is used by the driver to control the aircraft. The yoke 3 is connected to the elevator 6 via a control line connecting portion 5 described later, and the inclination (pitch) of the aircraft in the front-rear direction is controlled by moving the yoke 3 back and forth from the reference position. The yoke 3 is configured such that the greater the movement from the reference position, the greater the reaction force applied to the yoke 3 (the force that resists the driver's operation).

  The yoke operation detection unit 4 detects the operation of the yoke 3 by the driver. The yoke operation detection unit 4 outputs the detected operation of the yoke 3 to the control line connection unit control ECU 11 as yoke operation information.

  The control line connection portion 5 mechanically connects the yoke 3 and the elevator 6. The control line connection unit 5 transmits an operation input to the yoke 3 by the driver to the elevator 6. The control line connection unit 5 includes an input side gear ratio variable gear 13 coupled to the yoke 3, an output side gear ratio variable gear 14 coupled to the elevator 6, and a connection switching unit coupled to these variable gears 13, 14. 15.

  The connection switching unit 15 is electrically connected to the aircraft control ECU 10 and the control line connection unit control ECU 11. The connection switching unit 15 switches between the connection state and the non-connection state of the input side gear ratio variable gear 13 and the output side gear ratio variable gear 14 in accordance with a signal from the control line connection unit control ECU 11. The connection switching unit 15 disconnects the connection between the yoke 3 and the elevator 6 by bringing the input side gear ratio variable gear 13 and the output side gear ratio variable gear 14 into a disconnected state. Further, the connection switching unit 15 puts the input side gear ratio variable gear 13 and the output side gear ratio variable gear 14 into a connected state when signals from the aircraft control ECU 10 and the control line connection unit control ECU 11 are cut off due to a failure or the like. As a result, the yoke 3 and the elevator 6 are connected, and the operation input of the yoke 3 by the driver can be transmitted to the elevator 6.

  The elevator 6 is a moving blade that is provided on the horizontal tail of the aircraft and controls the inclination (pitch) of the aircraft in the front-rear direction. When the input side gear ratio variable gear 13 and the output side gear ratio variable gear 14 are in a connected state, the elevator 6 is driven up and down according to the operation input of the yoke 3 by the driver.

  The elevator drive detection unit 7 detects the drive of the elevator 6. The elevator drive detection unit 7 outputs the detected drive of the elevator 6 to the control line connection unit control ECU 11 as elevator drive information.

  The input side actuator 8 is electrically connected to the aircraft control ECU 10 and mechanically connected to the input side gear ratio variable gear 13. The input side actuator 8 drives the input side gear ratio variable gear 13 in accordance with a signal from the aircraft control ECU 10.

  The output side actuator 9 is electrically connected to the aircraft control ECU 10 and mechanically connected to the output side gear ratio variable gear 14. The output side actuator 9 drives the output side gear ratio variable gear 14 in accordance with a signal from the aircraft control ECU 10.

  The input side actuator 8 and the output side actuator 9 adjust the operation reaction force applied to the yoke 3 according to the reaction force adjustment signal output from the aircraft control ECU 10. Specifically, the input-side actuator 8 and the output-side actuator 9 are connected to the variable gear 13 and the output-side gear ratio variable gear 14 and the output-side gear ratio variable gear 14 so as to have opposite phases with respect to each other. By driving each 14, the yoke 3 is moved while the movement of the elevator 6 is fixed, that is, the operation input to the driver's yoke 3 is invalidated. In this state, the input side actuator 8 and the output side actuator 9 perform adjustments such as reducing the operation reaction force by applying a force corresponding to the reaction force adjustment signal to the yoke 3. Such adjustment may be realized by using one actuator and a phase inverting device instead of the two actuators 8 and 9.

  The warning unit 12 warns the driver about the flight status of the aircraft by a signal from the aircraft control ECU 10. The warning unit 12 includes a speaker, a warning lamp, and a yoke vibration actuator. The warning unit 12 warns the driver by sound output from a speaker or lighting of a warning lamp. The warning unit 12 warns the driver by vibrating the yoke 3 by the yoke vibration actuator.

  The aircraft control ECU 10 determines whether or not the driver's operation is appropriate based on the aircraft behavior information output from the aircraft behavior detection unit 2. Specifically, when the aircraft control ECU 10 recognizes that the aircraft is approaching a dangerous state such as a stalled state due to an increase in the angle of attack or an excessive speed based on the aircraft behavior information, the operation of the driver is appropriate. It is determined that it is not.

  When the aircraft control ECU 10 determines that the driver's operation is not appropriate, the aircraft control ECU 10 outputs an inappropriate operation warning signal to the warning unit 12 to warn the driver that the operation is not appropriate. When the aircraft control ECU 10 outputs an inappropriate operation warning signal, the driver performs an appropriate operation within a predetermined time based on the yoke operation information of the yoke operation detection unit 4 acquired through the control line connection unit control ECU 11. It is determined whether or not it has been changed.

  If the aircraft control ECU 10 determines that the driver has not changed the operation appropriately, the aircraft control ECU 10 may perform an operation that is less appropriate for the input side actuator 8, the output side actuator 9, and the control line connection unit control ECU 11. A reaction force adjustment signal for adjusting the operation reaction force of the yoke 3 is output. Further, when the aircraft control ECU 10 outputs the reaction force adjustment signal, the aircraft control ECU 10 is disconnected from the connection switching unit 15 until a predetermined end determination (for example, determination that the driver has sufficiently returned to an appropriate operation) is performed. Output a continuation signal.

  When the control line connection control ECU 11 receives the reaction force adjustment signal from the aircraft control ECU 10, the control line connection control ECU 11 outputs a disconnection state switching signal for disabling the input side gear ratio variable gear 13 and the output side gear ratio variable gear 14. Output to the connection switching unit 15. The control line connection unit control ECU 11 controls the control line connecting the yoke 3 and the elevator 6 based on the yoke operation information output from the yoke operation detection unit 4 and the elevator drive information output from the elevator drive detection unit 7. Monitor whether is functioning properly. When the control line connection control ECU 11 determines that the control line is not functioning normally when the input side gear ratio variable gear 13 and the output side gear ratio variable gear 14 are not connected, the input side gear ratio A connection state switching signal for setting the variable gear 13 and the output side gear ratio variable gear 14 to the connected state (that is, directly connecting the yoke 3 and the elevator 6) is output to the connection switching unit 15.

  Next, the operation of the steering assistance device 1 will be described with reference to the drawings. Hereinafter, an example will be described in which the yoke 3 is pulled from the center reference position to the rear side (driver side), the angle of attack increases, and a stalled state is approached.

  As shown in FIGS. 2 and 3, the aircraft control ECU 10 determines that the position of the yoke 3 is in a stalled state when the yoke 3 is pulled and the predetermined condition is satisfied (for example, as shown in FIG. Whether or not the driver's operation is appropriate (when the vehicle approaches the stall operation region T that is likely to become more than a predetermined threshold) (whether the yoke 3 is pulled too much and the vehicle is too close to the stall operation region T). (S1). Note that the position of the stall operation region T in FIG. 2 varies depending on the flight state such as the speed and attitude of the aircraft.

  If the aircraft control ECU 10 determines that the driver's operation is appropriate, the aircraft control ECU 10 repeats the determination in step S1 until a predetermined end determination (for example, determination that the driver has sufficiently returned to the appropriate operation) is made. . On the other hand, when it is determined that the driver is pulling the yoke 3 too much, the aircraft control ECU 10 outputs an inappropriate operation warning signal to the warning unit 12 to warn that the yoke 3 is pulled too much (S2). The warning unit 12 warns the driver by vibration and sound of the yoke 3 and lighting of a warning lamp.

  Thereafter, the aircraft control ECU 10 determines whether or not the driver has changed to an appropriate operation within a predetermined time based on the yoke operation information of the yoke operation detection unit 4 acquired through the control line connection unit control ECU 11 (yoke Whether or not 3 is returned to the front side is determined (S3).

  When it is determined that the driver has returned the yoke 3 to the front side, the aircraft control ECU 10 returns to step S1 and repeats the process after a predetermined time has elapsed. On the other hand, if the aircraft control ECU 10 determines that the driver has not returned the yoke 3 to the front side, the aircraft control ECU 10 outputs a reaction force adjustment signal to the input side actuator 8, the output side actuator 9, and the control line connection unit control ECU 11 (S4). ).

  When the control line connection unit control ECU 11 receives the reaction force adjustment signal from the aircraft control ECU 10, the control line connection unit control ECU 11 outputs a non-connection state switching signal to the connection switching unit 15. When receiving the non-connection state switching signal, the connection switching unit 15 switches the input side gear ratio variable gear 13 and the output side gear ratio variable gear 14 to the non-connection state, and disconnects the connection between the yoke 3 and the elevator 6. The input-side actuator 8 and the output-side actuator 9 apply a force to the yoke 3 while fixing the movement of the elevator 6 to lighten the reaction force against an inappropriate operation of pulling the yoke 3 to the rear side. Is guided so that the operation becomes closer to the stalled state.

  According to the steering assistance device 1 according to the present embodiment described above, when it is determined that the operation of the yoke 3 by the driver is an improper operation that may cause a stalled state, the driver's operation is performed. Adjustment is performed to reduce the reaction force so that the operation approaches the stalled state. As a result, the yoke 3 being operated moves beyond the driver's expectation, so that the driver can be surely notified that the operation is not appropriate. Moreover, by moving the yoke 3 being operated beyond the driver's expectation, it is possible to give the driver a chance to perform an appropriate operation, and to induce a reaction such as the driver returning the operation in a reflective manner. Thus, the safety of the aircraft can be improved.

  Further, according to the steering assist device 1, the operation reaction force applied to the yoke 3 is adjusted in a state in which the driver's operation input to the yoke 3 is invalidated. Even if the operation state becomes less appropriate, it is possible to avoid the movement being reflected in the movement of the aircraft.

  As described above, the case where there is a possibility that the aircraft may be stalled by the operation of the driver has been described as an example. However, the steering assist device 1 according to the present embodiment can be applied to various other situations. For example, the present invention can also be applied to a case where there is a possibility that the aircraft is overspeeded by pushing the yoke 3 or the throttle too much. In this case, after the warning, the operation input to the yoke 3 and the throttle is invalidated, and the operation reaction force of the yoke 3 and the throttle is applied or reduced so that the operation is accelerated. As a result, the yoke 3 and the throttle move to the acceleration side beyond the driver's expectation, so that the driver can be surely informed that the speed may be exceeded and the operation is not appropriate. Reactions such as operating to the deceleration side can be guided.

  In addition, when the aileron (auxiliary wing) of the aircraft is driven by the rotation operation of the yoke 3 and there is a possibility that the bank is attached due to the yoke 3 being rotated too much and a stalling state may occur, the yoke The driver inputs that the operation input to 3 is invalidated and the operation reaction force of the yoke 3 is applied or reduced so that the operation is more like a bank. Can be surely informed, and a reaction such as a driver returning the operation in a reflective manner can be guided.

  Furthermore, when landing, when pulling of the yoke 3, that is, causing the nose is not sufficient, after the warning, the operation input to the yoke 3 is invalidated and the operation of the yoke 3 is performed so that the nose is further lowered. By changing the operation reaction force, the driver suddenly moves the yoke 3 forward, so that the driver feels that the fuselage is moving toward the ground, and there is a risk that the driver will crash. Can be reliably notified, and a reaction such as pulling the yoke 3 in a reflective manner can be guided.

  In addition, when there is an obstacle such as a building in the traveling direction of the aircraft, after the warning, the operation input to the yoke 3 is invalidated and an operation reaction force is applied to the yoke 3 so that the operation closer to the obstacle is performed. This gives the driver the feeling that the aircraft is heading towards the obstacle and can be sure to inform the driver that it may collide with the obstacle, avoiding obstacles reflectively. Thus, a reaction such as operation of the yoke 3 can be guided.

(Second Embodiment)
Next, a steering assistance device 21 according to a second embodiment will be described with reference to the drawings. As shown in FIG. 4, the steering assist device 21 according to the second embodiment is different from the first embodiment in the configuration of the control line connection unit 23 and the control line connection unit control ECU (operation input invalidation). Means) Only the function 22 is different.

  The control line connection unit 23 of the steering assist device 21 includes an input side clutch 24, an output side clutch 25, a clutch connection switching unit 26, and an actuator connection switching unit 27. The input side clutch 24 is connected to the yoke 3 and is connected to the input side actuator 8 via the actuator connection switching unit 27. The output side clutch 25 is connected to the elevator 6 and is connected to the output side actuator 9 via the actuator connection switching unit 27.

  The clutch connection switching unit 26 is electrically connected to the control line connection unit control ECU 22, and according to a signal from the control line connection unit control ECU 22, the input side clutch 24 and the output side clutch 25 are connected and disconnected. Switch.

  The actuator connection switching unit 27 is electrically connected to the control line connection unit control ECU 22, and a connection state and a non-connection state between the input side clutch 24 and the input side actuator 8 according to a signal from the control line connection unit control ECU 22. Switch between and. Further, the actuator connection switching unit 27 switches between a connection state and a non-connection state between the output side clutch 25 and the output side actuator 9 in accordance with a signal from the control line connection unit control ECU 22.

  In the steering assist device 21, the input side clutch 24 and the output side clutch 25 are normally connected while the clutches 24, 25 and the actuators 8, 9 are not connected. In this case, the operation input of the yoke 3 by the driver is transmitted to the elevator 6 through the input side clutch 24, the output side clutch 25, and the clutch connection switching unit 26. A gear or the like for facilitating the operation may be interposed between the yoke 3 and the elevator 6.

  Further, in the steering assist device 21, when the operation reaction force of the yoke 3 is adjusted, the reaction force adjustment signal is sent from the aircraft control ECU 10 to the input side actuator 8, the output side actuator 9, and the control line connection unit control ECU 22. Is output. The control line connection unit control ECU 22 outputs a non-connection state switching signal to the clutch connection switching unit 26 and outputs a connection state switching signal to the actuator connection switching unit 27 in accordance with the reaction force adjustment signal.

  The clutch connection switching unit 26 switches the input side clutch 24 and the output side clutch 25 to the non-connected state according to the non-connected state switching signal, and disconnects the connection between the yoke 3 and the elevator 6. The actuator connection switching unit 27 switches the input side clutch 24 and the input side actuator 8 to the connected state and switches the output side clutch 25 and the output side actuator 9 to the connected state according to the connection state switching signal. In this manner, in the steering assistance device 21, the yoke 3 can be moved while the movement of the elevator 6 is fixed by the output side actuator 9, and the operation input to the driver's yoke 3 is invalidated. In this state, the input side actuator 8 performs adjustment such as reducing the operation reaction force by applying a force corresponding to the reaction force adjustment signal to the yoke 3.

  Next, the operation of the steering assist device 21 will be described with reference to the drawings.

  As shown in FIG. 3, the aircraft control ECU 10 determines whether or not the driver's operation is appropriate when the predetermined condition is satisfied by the operation of the yoke 3 (S <b> 1). If the aircraft control ECU 10 determines that the driver's operation is appropriate, the aircraft control ECU 10 repeats the determination in step S1 until a predetermined end determination is made.

  On the other hand, if the aircraft control ECU 10 determines that the driver's operation is not appropriate, the aircraft control ECU 10 outputs an inappropriate operation warning signal to the warning unit 12 to warn that the driver's operation is not appropriate (S2). The warning unit 12 warns the driver by vibration and sound of the yoke 3 and lighting of a warning lamp.

  Thereafter, the aircraft control ECU 10 determines whether the driver has changed to an appropriate operation within a predetermined time based on the yoke operation information of the yoke operation detection unit 4 acquired through the control line connection unit control ECU 22. (S3).

  When the aircraft control ECU 10 determines that the driver has changed to an appropriate operation, the aircraft control ECU 10 returns to step S1 and repeats the process after a predetermined time has elapsed. On the other hand, when it is determined that the driver has not changed to an appropriate operation, the aircraft control ECU 10 outputs a reaction force adjustment signal to the input side actuator 8, the output side actuator 9, and the control line connection unit control ECU 22 (S4). ).

  The control line connection unit control ECU 22 outputs a non-connection state switching signal to the clutch connection switching unit 26 and outputs a connection state switching signal to the actuator connection switching unit 27 in accordance with the reaction force adjustment signal. The clutch connection switching unit 26 switches the input side clutch 24 and the output side clutch 25 to the non-connected state according to the non-connected state switching signal, and disconnects the connection between the yoke 3 and the elevator 6. The actuator connection switching unit 27 switches the input side clutch 24 and the input side actuator 8 to the connected state and switches the output side clutch 25 and the output side actuator 9 to the connected state according to the connection state switching signal. In this way, the invalidation of the operation input to the driver's yoke 3 is realized. Then, a force is applied to the yoke 3 while the movement of the elevator 6 is fixed, and the operation reaction force against the inappropriate operation of the yoke 3 is lightened, so that the operation of the driver becomes a less appropriate operation. To do.

  Also in the steering assistance device 21 according to the second embodiment described above, the same effects as those of the steering assistance device 1 according to the first embodiment can be obtained. In addition, as a structure for implement | achieving such an effect, it is not restricted to the aspect using the gear ratio variable gear and clutch mentioned above, For example, in the aircraft which employ | adopted fly-by-wire, the yoke 3 and the elevator 6 are electrically A mode of disconnecting the connection is conceivable.

(Third embodiment)
A steering assistance device 31 according to a third embodiment will be described with reference to the drawings. As FIG. 5 shows, the steering assistance apparatus 31 which concerns on 3rd Embodiment differs from 1st Embodiment by the point with which the vehicle which drive | works the ground instead of an aircraft.

  The steering support device 31 includes a traveling state detection unit 32, an operation unit (control unit) 33, an operation detection unit 34, a control line connection unit 35, and a drive unit 36. Further, the steering assist device 31 includes a drive detection unit 37, a connection unit control actuator 38, a vehicle control ECU (determination unit, reaction force adjustment unit) 39, a control line connection unit control ECU (operation input invalidation unit) 40, and a warning. A portion 41 is provided.

  The vehicle control ECU 39 has the same function as the aircraft control ECU 10 in the first embodiment. The vehicle control ECU 39 is electrically connected to the traveling state detection unit 32, the control line connection unit 35, the connection unit control actuator 38, and the control line connection unit control ECU 40.

  The control line connection unit control ECU 40 has the same function as the control line connection unit control ECU 11 in the first embodiment. The control line connection unit control ECU 40 is electrically connected to the operation detection unit 34, the control line connection unit 35, and the drive detection unit 37.

  The traveling state detection unit 32 includes various sensors such as a vehicle speed sensor and an acceleration sensor, and detects the traveling state of the vehicle. The traveling state detection unit 32 outputs the detected traveling state of the vehicle to the vehicle control ECU 39 as traveling state information.

  The operation unit 33 is for a driver to operate the vehicle, and includes a vehicle handle, an accelerator pedal, a brake pedal, and the like. The operation of the operation unit 33 controls a drive unit 36 described later. The operation detection unit 34 detects an operation of the operation unit 33 by the driver. The operation detection unit 34 outputs the detected operation of the operation unit 33 as operation information to the control line connection unit control ECU 40.

  The control line connection unit 35 has the same function as the control line connection unit 5 in the first embodiment, for example. The control line connection unit 35 disconnects the connection between the operation unit 33 and the drive unit 36 based on a signal from the control line connection unit control ECU 40, and invalidates the driver's operation input to the operation unit 33.

  The drive unit 36 is composed of a vehicle engine, wheels, brakes, and the like, and reflects the driver's operation input to the operation unit 33 in the traveling state of the vehicle. The drive detection unit 37 detects the drive state of the drive unit 36. The drive detection unit 37 outputs the detected drive state as drive information to the control line connection unit control ECU 40.

  The connection part control actuator 38 corresponds to, for example, the input side actuator 8 and the output side actuator 9 in the first embodiment, and is connected to the control line connection part 35. The connection part control actuator 38 adjusts the operation reaction force in the operation part 33 by applying a force to the operation part 33 via the control line connection part 35 in accordance with a reaction force adjustment signal from the vehicle control ECU 39.

  The warning unit 41 has the same configuration as the warning unit 12 in the first embodiment. The warning unit 41 warns the driver about the running state of the vehicle in accordance with a signal from the vehicle control ECU 39.

  The vehicle control ECU 39 determines whether or not the driver's operation is appropriate based on the traveling state information output from the traveling state detection unit 32. Specifically, the vehicle control ECU 39 determines that the driver's operation is not appropriate when the vehicle control ECU 39 recognizes that the vehicle is approaching a dangerous state such as a skid state based on the traveling state information.

  When the vehicle control ECU 39 determines that the driver's operation is not appropriate, the vehicle control ECU 39 outputs an inappropriate operation warning signal to the warning unit 41 to warn the driver that the operation is not appropriate. When the vehicle control ECU 39 outputs an inappropriate operation warning signal, the driver changes to an appropriate operation within a predetermined time based on the operation information of the operation detection unit 34 acquired through the control line connection unit control ECU 40. Determine whether or not.

  When the vehicle control ECU 39 determines that the driver has not changed the operation appropriately, the vehicle control ECU 39 sets the operation unit 33 so that the connection unit control actuator 38 and the control line connection unit control ECU 40 are operated more inappropriately. A reaction force adjustment signal for adjusting the operation reaction force is output.

  When the control line connection control ECU 40 receives the reaction force adjustment signal from the vehicle control ECU 39, the control line connection control ECU 40 connects the operation unit 33 and the drive unit 36 according to the situation (for example, when there is a possibility that the vehicle is in a skidding state, the steering wheel And a connection state switching signal for disconnecting the wheel) is output to the control line connection unit 35. Further, the control line connecting unit control ECU 40 has a normal control line connecting the operation unit 33 and the drive unit 36 based on the operation information output from the operation detection unit 34 and the drive information output from the drive detection unit 37. Monitor whether it is functioning properly. When the control line connection unit control ECU 40 determines that the control line is not functioning normally in a state where the connection between the operation unit 33 and the drive unit 36 is disconnected, the control line connection unit control ECU 40 connects the operation unit 33 and the drive unit 36. The connection state switching signal is output to the control line connection unit 35.

  Next, the operation of the steering assist device 31 will be described with reference to the drawings.

  As shown in FIG. 3, the vehicle control ECU 39 determines whether or not the driver's operation is appropriate when a predetermined condition is satisfied by the operation of the operation unit 33 (S1). When the vehicle control ECU 39 determines that the driver's operation is appropriate, the vehicle control ECU 39 repeats the determination in step S1 until a predetermined end determination is made.

  On the other hand, if the vehicle control ECU 39 determines that the driver's operation is not appropriate, the vehicle control ECU 39 outputs an inappropriate operation warning signal to the warning unit 41 to warn that the driver's operation is not appropriate (S2). The warning unit 41 gives a warning to the driver by vibration or sound of the operation unit 33, lighting of a warning lamp, or the like.

  Thereafter, the vehicle control ECU 39 determines whether or not the driver has changed to an appropriate operation within a predetermined time based on the operation information of the operation detection unit 34 acquired through the control line connection unit control ECU 40 ( S3).

  When it is determined that the driver has changed to an appropriate operation, the vehicle control ECU 39 returns to step S1 and repeats the process after a predetermined time has elapsed. On the other hand, when it is determined that the driver has not changed to an appropriate operation, the vehicle control ECU 39 outputs a reaction force adjustment signal to the connection control actuator 38 and the control line connection control ECU 40 (S4).

  The control line connection unit control ECU 40 outputs a non-connection state switching signal to the control line connection unit 35 in response to the reaction force adjustment signal. The control line connection unit 35 disconnects the connection between the operation unit 33 and the drive unit 36 in response to the non-connection state switching signal. In this manner, the invalidation of the operation input to the driver operation unit 33 is realized. Then, while maintaining the movement of the drive unit 36, the connection unit control actuator 38 applies a force to the operation unit 33 to reduce an operation reaction force with respect to an inappropriate operation of the operation unit 33, so that the driver's operation can be performed. Guide the operation to be less appropriate.

  Also in the steering assistance device 31 according to the third embodiment described above, the same effects as those in the steering assistance device 1 according to the first embodiment can be obtained. The configuration of the control line connection unit 35 may be the same as that of the control line connection unit 22 according to the second embodiment. For example, in a vehicle employing drive-by-wire, the operation unit 33 is electrically driven. The structure which cut | disconnects the connection with the part 36 may be sufficient.

  As a situation in which the steering support device 31 according to the present embodiment is specifically applied, for example, a case where the tire is locked due to the driver stepping on the brake too much may be mentioned. In this case, after the warning, the driver's operation input to the brake pedal is invalidated, and the reaction force of the brake pedal is reduced so that the driver depresses the brake pedal more. As a result, if the brake pedal moves beyond the driver's expectations, the driver can be surely informed that the tires may lock and that the operation is not appropriate, and the driver will reflect off the brake pedal. A reaction such as lifting a foot can be induced.

  Also, if there is a possibility that the driver will depress the accelerator pedal suddenly and the tire will turn idle, the operation input to the accelerator pedal will be invalidated after warning and the accelerator pedal will be depressed so that the driver will depress the accelerator pedal more. By reducing the operating reaction force, it is possible to reliably inform the driver that the tire is in an idle state and that the operation is not appropriate, and the driver reflexes the foot from the accelerator pedal. Can guide you.

  Furthermore, in the case where the driver may turn the steering wheel too much and the vehicle may slip, the operation input to the steering wheel is invalidated after warning and the steering wheel is operated so that the driver turns the steering wheel more. By reducing the operation reaction force of the vehicle, it is possible to reliably notify the driver that the vehicle may be in a skidding state and that the operation is not appropriate, and the driver will return the steering wheel in a reflective manner. Can guide you.

  In addition, when there are obstacles such as buildings in the traveling direction of the vehicle, after the warning, the operation input to the steering wheel and the accelerator pedal is invalidated and the steering wheel and the accelerator pedal are operated so as to make the operation closer to the obstacle. By applying an operational reaction force, the driver can feel that the vehicle is moving toward an obstacle and can reliably inform the driver that the vehicle may collide with the obstacle. It is possible to induce a reaction such as operating the steering wheel to avoid an object, or stepping on the brake pedal with the foot off the accelerator pedal.

  The present invention is not limited to the embodiment described above. For example, in the first and second embodiments, the case of particularly assisting the operation of the yoke 3 has been described. However, the present invention can also be suitably applied to the operation of a steering unit such as a ladder pedal or a handle of an aircraft. it can. Moreover, when adjusting the operation reaction force of the control unit such as the yoke 3, a mode in which the driver's operation input to the control unit is not invalidated may be used. In this case, the adjustment of the operation reaction force is performed with sufficient consideration of the behavior of the aircraft.
