  The present invention relates to a driving operation device that includes an operating member that is operated by a driver and that operates a vehicle according to the operation of the operating member by the driver.

  Conventionally, for example, a driving operation device with improved operation stability of an operation member as disclosed in JP-A-11-192960 has been developed. In this driving operation device, a joystick is used as an operating member, and the joystick and hand for operating the joystick are operated more in the direction away from the body than when the driver operates the joystick toward the body side. The amount of movement or operating force is reduced. Therefore, the operation of the joystick matches the characteristics of the human upper limb structure, and the operability is improved.

  However, in the above-described driving operation device, the amount of movement of the joystick and the hand changes depending on whether the joystick is operated toward the body side or the direction away from the body, but output such as acceleration / deceleration to the vehicle is performed. The operation amount (input) of the joystick with respect to is in a fixed relationship. Therefore, there is a problem that the vehicle cannot be operated by various input modes.

There is provided output means for outputting a third output value in consideration of the first output value based on one operation amount and the second output value based on the second operation amount of the second input unit.

  In this driving operation device, the operation member includes a first input unit and a second input unit that are independently operated, and the first and second output values based on the operation amounts of the two input units are taken into account. The output means outputs the third output value obtained in this way. In this case, a 2-input 1-output mechanism, for example, a planetary gear mechanism, is provided that inputs the operation amounts of the first and second input sections and operates the output member in relation to the input. A sensor for detecting the displacement amount of the output member may be provided, and the output of the sensor may be taken out as the third output value.

  The third output value including the first output value and the second output value may be a value obtained by simply adding the first and second output values, or the first and second output values and a predetermined constant. It is also possible to add the product of Further, it may be a value obtained from a product of the first and second output values or a mathematical expression appropriately set according to the purpose based on the first and second output values. In this case, it is preferable that the second output value is less sensitive to the operation amount than the first output value. As a result, the first output value can be used as the main output value, and the second output value can be used as the sub output value for fine adjustment, resulting in diversification of the setting of the third output value.

  Another feature of the driving operation device according to the present invention is that an operation member including a first input unit and a second input unit that are independently operated by a driver, and a first operation amount of the first input unit. First detection means for detecting, second detection means for detecting a second operation amount of the second input unit, and output means for outputting an output value based on the detected first and second operation amounts are provided. There is.

  In this driving operation device, the operation member includes a first input unit and a second input unit that are operated independently, and the detection means detects the operation amount of the two input units to obtain the output value. It is like that. In this case, a sensor for detecting the first and second operation amounts may be provided, and the detection values from the sensors may be combined by calculation to obtain an output value. Also in this case, it is preferable that the second detection means is less sensitive to the operation amount than the first detection means.

  Further, in common with the first to fourth aspects of the present invention, the first input unit includes a joystick that tilts in the left-right direction or the front-rear direction, a steering wheel that rotates, and the second input unit includes the first input. An input unit that rotates in the axial direction with respect to the unit, a lever provided near the first input unit, a push button, and the like can be appropriately selected and configured. For example, the operation of the first input unit can be a main operation, and the operation of the second input unit can be a subordinate operation for supplementing or adjusting the main operation. As a result, it is possible to obtain a driving operation device that can be operated by minute input.

  Another structural feature of the driving operation device of the present invention is that the first input portion and the second input portion are provided in one operation member. This facilitates the main operation and the subordinate operation.

Embodiments of a driving operation device according to the present invention will be described below with reference to the drawings.
(First embodiment)
The driving operation device according to the first embodiment includes an operation lever (joystick) 50 as an operation member shown in FIG. The operation lever 50 is provided in the vicinity of the driver's seat of the vehicle, and is tilted (turned) in the front-rear direction and the left-right direction with respect to the vehicle as a whole by the driver's operation.

  The control lever 50 is attached to a rod 51 having a round bar shape (shown by a two-dot chain line), a square columnar grip 52 attached to the upper end of the rod 51, and an upper end of the grip 52. The lower end portion of the rod 51 is fixed to the outer peripheral surface of the rotating shaft 54 arranged in the horizontal direction. An electric motor 55 for generating a reaction force for returning the operation lever 50 to the neutral position is attached to the rotating shaft 54, and the rotation angle of the rotating shaft 54 is detected near the end of the rotating shaft 54. An operation position sensor 56 is provided. The operation position sensor 56 detects the rotation angle of the rotation shaft 54 as an operation amount of the operation lever 50 in the front-rear direction.

  The trigger operation portion 53 is configured by projecting a rod-like trigger 53b obliquely downward from the circumferential surface of the cylindrical housing portion 53a with the central axis oriented in the horizontal direction, and inside the cylindrical housing portion 53a, there is a trigger. The rotation support shaft is connected to 53b and rotatably supports the trigger 53b, and the trigger 53b is set to an initial position (a position away from the grip 52 by a predetermined distance so that the driver can grip the grip 52 and the trigger 53b at the same time). ) Is provided (both not shown). In addition, an operation position sensor 57 that detects the rotation angle of the rotation support shaft as the operation amount of the trigger 53b is also provided inside the cylindrical housing portion 53a.

  Acceleration control and vehicle steering can be performed by operating the operation lever 50 and the trigger operation unit 53. In the case of acceleration control, the operation direction of the operation lever 50 is the front and rear, and when steering is performed, the operation direction of the operation lever 50 is the left and right. Further, the braking control of the vehicle can be performed by operating the operation lever 50 and the trigger operation unit 53. For example, the operation range of the operation lever 50 is divided by setting the front side as a portion that performs braking control and the rear side as a portion that performs acceleration control with the neutral position of the operation lever 50 as a boundary. In this case, it is preferable that the operation of the operation lever 50 in the front-rear direction or the left-right direction is a main operation, and the operation of the trigger operation unit 53 is a sub-operation.

  Next, the electric control unit of the driving operation device will be described with reference to FIG. In the electric control unit 20, the operation position sensors 56 and 57 and the operation position sensor (not shown) for detecting the operation amount in the left-right direction of the operation lever 50 are connected to the electric control device 21. The electric control device 21 is constituted by a microcomputer having a CPU 21a, a ROM 21b, a RAM 21c, etc., and controls the steering control device 22 in accordance with a detection value detected by an operation position sensor (not shown), which is detected by operation position sensors 56 and 57. The engine control device 23 and the brake control device 24 are controlled according to the detected value. The CPU 21a executes various programs input to the ROM 21b, and calculates data to be sent to the engine control device 23 and the like based on detection values detected by the operation position sensors 56 and 57 and the like.

  The steering control device 22 steers the vehicle left and right by controlling the steering actuator 25 according to the amount of displacement in the lateral direction of the vehicle body according to the operation of the operation lever 50 by the driver. That is, the electric control device 21 inputs the left-right displacement position of the operation lever 50 from an operation position sensor (not shown), and steers the vehicle in the left-right direction according to the steering angle corresponding to the input displacement position. . This steering angle is set to be “0” when the displacement position of the operation lever 50 is the neutral position.

  The engine control device 23 is controlled by the electric control device 21 based on detection values detected by the operation position sensors 56 and 57, and controls the acceleration of the vehicle by driving a throttle actuator 26 that controls the throttle opening. That is, the operation lever 50 is operated in the front-rear direction as the first input unit of the present invention to perform the main operation of acceleration control. The engine control device 23 is controlled by the electric control device 21 to drive the throttle actuator 26 based on the operation amount of the operation lever 50 that is the first operation amount detected by the operation position sensor 56.

  In addition, the trigger operation unit 53 is operated as a second input unit and performs a subordinate operation of acceleration control. The engine control device 23 drives the throttle actuator 26 under the control of the electric control device 21 based on the operation amount of the trigger 53b which is the second operation amount detected by the operation position sensor 57. The vehicle travels in an accelerated manner based on the output corresponding to the detected value of the operation position sensor 56, and further accelerates or decelerates the accelerated travel in a minute range by the output corresponding to the detected value of the operating position sensor 57.

The relationship between the detection value of the operation position sensor 56 and the output to the vehicle and the relationship between the detection value of the operation position sensor 57 and the output to the vehicle are input to the ROM 21b of the electric control device 21 as mapped data. Has been. For example, when the detection value X of the operating position sensor 56 is the output value P when the X _A and P _A, the relationship of the detected value X _A and the output value P _A is as shown in FIG. 3, the operating position sensor 57 when the detection value X of the output value P when the X _B and P _B, the relationship of the output value P _B and the detection value X _B is as shown in FIG. Then, the output value P output to the engine control unit 23 is the sum or difference of P _A and P _B. In this case, the output value P output to the vehicle can be the sum or difference of values obtained by multiplying the output value P _A or the output value P _B by a predetermined coefficient.

It is also possible to output value and the output value P _A product of the output value P _B, furthermore, can also be the output value of the combined value in the output value P _A and the output value P _B and the predetermined relationship. As the composite value having a predetermined relationship, a value obtained by setting a mathematical formula based on the detected value according to the purpose and using the mathematical formula can be used. The calculation of the composite value and the like is performed by the electric control device 21 and is determined based on the third operation amount obtained in relation to the first operation amount and the second operation amount. Then, the electric control device 21 transmits this combined value as a signal to the engine control device 23.

In this case, reduce the sensitivity of the output value P _A based on the operation amount of the operation lever 50 with respect to the output value P _B based on the operation amount of the trigger operating portion 53, or the operation amount of the trigger operating portion 53 It is preferable to reduce the sensitivity of the operation position sensor 56 that detects the operation amount of the operation lever 50 with respect to the operation position sensor 57 to be detected. As shown in FIGS. 3 and 4, this “low sensitivity” means that, for example, when the operation lever 50 and the trigger operation unit 53 are operated by the same distance, the output value P _B corresponding to the trigger operation unit 53. There refers to small compared to the output value P _a corresponding to the operation lever 50.

Specifically, when the operation lever 50 and the trigger operation unit 53 are operated by the same distance, the output value P _B corresponding to the trigger operation unit 53 is equal to the operation lever 50 even if the detected value of the operation amount is the same. It is achieved by providing a map such as smaller as compared with the output value P _a corresponding to. Further, the output values corresponding to the operation lever 50 and the trigger operation unit 53 are provided with the same map, and once the output value corresponding to the operation lever 50 and the trigger operation unit 53 is obtained, the output coefficient is set to one value. By multiplying, the output value P _B corresponding to the trigger operation unit 53 may be made smaller than the output value P _A corresponding to the operation lever 50.

  As a result, the vehicle can be operated in various ways. As described above, in the driving operation device provided with the operation lever 50, the normal acceleration control of the vehicle can be performed by operating the operation lever 50 in the front-rear direction, and further, by operating the trigger operation unit 53, Further, the acceleration control can be controlled to accelerate or decelerate within an arbitrary minute range. As a result, diversity occurs in the operation of the vehicle. The brake control device 24 is controlled by the electric control device 21 based on the forward displacement position of the rotating shaft 54 detected by the operation position sensor 56, and drives the brake actuator 27 that applies a braking force to the vehicle.

  In this configuration, when the driver operates the vehicle, the ignition switch is turned on so that the vehicle can be started. Next, when the driver rotates the operation lever 50 and the operation lever 50 is displaced backward from the neutral position, the operation position sensor 56 detects the displacement position. A signal corresponding to the displacement position of the operation lever 50 is supplied to the electric control device 21, and the electric control device 21 outputs a control signal for opening the throttle to the engine control device 23. Then, when the engine control device 23 controls the throttle actuator 26, the vehicle starts traveling forward according to the displacement position of the operation lever 50.

  Further, when the driver operates the operation lever 50 and the operation lever 50 is displaced to the right side of the vehicle with respect to the neutral position in the left-right direction of the vehicle, an operation position sensor (not shown) detects the displacement position. A signal corresponding to the displacement position of the operation lever 50 is supplied to the electric control device 21. The electric control device 21 outputs a steering control signal to the steering control device 22, and the tearing control device 22 responds to the steering control signal. To control the steering actuator 25. As a result, the vehicle turns to the right with the steering angle increasing to the right. Further, when the operation lever 50 is displaced to the left side of the vehicle from the neutral position, the steering angle increases to the left side and the vehicle turns to the left.

  Further, when the operation lever 50 is displaced forward from the neutral position in the rotation direction by the operation of the driver, the operation position sensor 56 detects the displacement position, and a signal corresponding to the displacement position is transmitted to the electric control device 21. Then, the electric control device 21 calculates the value of the braking force according to the displacement position by arithmetic processing, and outputs the control signal to the brake control device 24. Then, when the brake control device 24 controls the brake actuator 27, the vehicle brakes forward traveling according to the displacement position of the operation lever 50.

(Second Embodiment)
FIG. 5 shows an operation lever 60 provided in the driving operation device according to the second embodiment of the present invention. In the operation lever 60, a cylindrical horizontal gripping portion 62 as a first input portion disposed in the horizontal direction is fixed to an upper end of a rod-shaped rod 61 disposed above and below. Then, a short cylindrical rotating part 62a that is rotatable about an axis with respect to the horizontal holding part 62 is attached to one end of the horizontal holding part 62, and extends vertically to one end of the rotating part 62a. A cylindrical vertical gripping part 63 as a second input part is fixed. Further, a rotating shaft 64 connected to the vertical gripping portion 63 is provided inside the horizontal gripping portion 62 and the rotating portion 62a, and the other end of the rotating shaft 64 detects the rotation angle of the rotating shaft 64. The operation position sensor 65 is provided. The operation position sensor 65 detects the rotation angle of the rotation shaft 64 as an operation amount in the front-rear direction of the vertical grip portion 63.

  A spring body 66 for returning the vertical grip 63 to the initial position (neutral position with respect to the rod 61) is provided on the outer peripheral portion of the rotating shaft 64. The rest of the configuration of the driving operation device provided with the operation lever 60 is the same as that of the driving operation device provided with the operation lever 50. Therefore, the same reference numerals are given to the same parts in the figure.

  In the driving operation device provided with the operation lever 60, the operation of tilting the entire operation lever 60 in the front-rear direction with the horizontal gripping portion 62 is the main operation, and the operation amount is the first operation amount. In addition, an operation of holding the vertical gripping portion 63 and tilting the vertical gripping portion 63 in the front-rear direction with respect to the rod 61 is a slave operation, and the operation amount is a second operation amount. Then, the third operation amount is obtained by adding the second operation amount to the first operation amount. According to this, the main operation and the subordinate operation can be performed by placing the palm on the horizontal gripping portion 62 of the operation lever 60 to grip the vertical gripping portion 63 and operating both the horizontal gripping portion 62 and the vertical gripping portion 63 in the front-rear direction. Easy to operate. About the other effect, it is the same as that of the driving | operation operating device provided with the operation lever 50 mentioned above.

(Modification)
As a modification of the operation lever 60, the horizontal gripping portion 62 is installed in a direction orthogonal to the rotation shaft 54, and the direction in which the horizontal gripping portion 62 is operated and the direction in which the vertical gripping portion 63 is operated are different. Can do. Further, instead of the horizontal gripping part 62, the rotating part 62a, the vertical gripping part 63, the rotating shaft 64, the operation position sensor 65 and the spring body 66, the gripping part 13 or gripping provided with the rotation operation part 13a and the operation position sensor 19 It is also possible to perform the slave operation by rotating the rotation operation unit 13a around the axis using the unit 34.

  In this case, the gripping portions 13 and 34 become the first input portion, and the rotation operation portion 13a becomes the second input portion. The operation amount of the gripping units 13 and 34 is the first operation amount, and the operation amount of the rotation operation unit 13a is the second operation amount. Similarly, for the operation lever 50, instead of the grip portion 52, the trigger operation portion 53, and the operation position sensor 57, the grip portion 13 or the grip portion 34 including the rotation operation portion 13a and the operation position sensor 19 can be used. .

  Furthermore, as a modification common to the operation levers 50 and 60, a brake mechanism for restricting the movement of the operation levers 50 and 60 can be provided on the trigger operation unit 53 and the rotation shaft 64 that perform the slave operation. As this mechanism, for example, as shown in FIG. 6, the upper end of the wire 70 is connected to the trigger 53 b of the trigger operation unit 53, and the fastening ring 72 provided with the friction pad 71 at the lower end of the wire 70. Can be used, and a mechanism configured by winding the ring 72 around the outer periphery of the rotating shaft 54 can be used.

  According to this mechanism, when the grip portion 52 and the trigger 53b are gripped together and the trigger 53b is moved to the grip portion 52 side, the wire 70 tightens the ring 72 and the friction pad 71 is pressed against the peripheral surface of the rotary shaft 54. . As a result, the rotation shaft 54 is prevented from rotating according to the magnitude of the frictional force with the friction pad 71, and the operation lever 50 is braked together with the rotation shaft 54. Further, when the trigger 53b is released, the pressure contact with the rotation shaft 54 by the friction pad 71 is released, and the rotation shaft 54 and the operation lever 50 are easily moved.

  In this case, the frictional force f between the rotating shaft 54 and the friction pad 71 is set to be proportional to the operation amount X of the trigger 53b detected by the operation position sensor 57, as shown in FIG. As a result, the output to the vehicle is made close to the target by the main operation by the operation of the operation lever 50, and when the output to the vehicle approaches the target output, the braking force is applied to the operation lever 50 by the slave operation by the trigger 53b. While giving, the output with respect to a vehicle can be made to reach a target output. As a result, the operation lever 50 is not shaken or vibrated, and the vehicle operation is stabilized.

  This brake mechanism can also be used for the operation lever 60. In this case, the vertical grip 63 is tilted with respect to the rod 61 so that the friction pad 71 comes into pressure contact with the rotating shaft 54. In addition, the brake mechanism can use a motor instead of the wire 70. In this case, a mechanism is used in which the motor tightens the ring 72 based on the detection values of the operation position sensors 57 and 65. This also has the same effect.

  In the driving operation device according to the first and second embodiments and the modified example thereof, the operation amount can be not only the displacement amount but also the operation force. In this case, a pressure sensor is used as the sensor. In the first and second embodiments and the modifications thereof, the first operation amount by the operation of the operation levers 50 and 60 as a whole and the second operation amount by the operation of the trigger operation unit 53 and the vertical gripping unit 63 are associated with the electric. The third operation amount is determined and the output value is obtained based on the third operation amount. However, the output value can be obtained mechanically. For example, using a differential mechanism such as a planetary gear, the operation amounts from the two input units are combined and output. In this case, the operation amount on the output side which is the third operation amount is detected by the sensor, and the detected value is sent to the electric control device 21 as a signal.

  Further, the operation member used in the driving operation device of the present invention is not limited to the joystick, and a steering wheel can be used. Further, only the left and right parts are left except the upper and lower parts of the steering, and the left and right parts operate the vehicle. It is also possible to use an operation member adapted to perform the above.
