Description

  The present invention relates to a steering apparatus including a steering operator for steering a wheel.

  Normally, in a steering device, a driver operates a steering wheel (steering operator) at an arbitrary angle in order to steer a wheel. In this type of steering device, a structure is adopted in which the position of the steering wheel is adjusted according to the physique and preferences of the driver.

  For example, in “POWER OPERATED TILT AND TESCOSCOE ASSEMBLY” disclosed in Patent Document 1, a fixed lower portion, an intermediate portion that is nested in the lower portion, and an inclinable engagement with the intermediate portion. And a steering wheel is connected to the upper part. For this reason, in particular, the steering wheel can be tilted in the front-rear direction as viewed from the driver.

  Patent Document 2 discloses a drive motor for tilting and telescopic operation, power transmission means for transmitting a driving force of the driving motor to a steering shaft, and converting the driving force into a tilting operation and a telescopic operation.

US Pat. No. 3,396,600 JP 61-36056 A

  In the above prior art, the angular position in the front-rear direction of the steering wheel is adjusted in accordance with the physique of the driver in a neutral position where the steering is not performed (straightly traveling state). Therefore, once the position is adjusted, the position is usually not changed, and there is no idea that the position of the steering wheel is changed after the vehicle has traveled.

  By the way, the situation where the vehicle is traveling at a low speed is assumed to be during turning at a corner, during switching and operation for parking, and in such a case, the amount of operation with respect to the steering wheel increases. On the other hand, the situation where the vehicle is traveling at high speed is assumed to be traveling on a highway, traveling straight on a clear road, etc. In such a case, the amount of operation on the steering wheel decreases.

  In situations where the amount of operation on the steering wheel is large, it is easier to operate when the steering wheel is close to the hand, and in situations where the amount of operation on the steering wheel is small, the steering wheel must be slightly separated. Easy to operate.

  Embodiments of a steering apparatus according to the present invention will be described below with reference to FIGS.

  As shown in FIG. 1, a steering device 10 according to the present embodiment is provided facing a driver seat 14 of a vehicle 12, and a steering wheel 16 (steering) for steering a wheel (not shown) of the vehicle 12. Control). The steering wheel 16 is gripped and operated by a driver 18 seated on the driver's seat 14.

  The steering wheel 16 is coupled to a steering column assembly 20 as shown in FIG. The steering column assembly 20 includes a steering wheel displacement mechanism 22 (a steering operator displacement mechanism) that changes the position of the steering wheel 16 according to the speed (vehicle speed) of the vehicle 12. The steering column assembly 20 having the steering wheel displacement mechanism 22 is covered with a cover 24.

  As shown in FIGS. 3 and 4, the steering column assembly 20 includes a substantially cylindrical column 26, and an upper steering shaft 30 is rotatably disposed in the column 26 via a cylinder body 28. . One end of the upper steering shaft 30 is coaxially connected to the steering wheel 16 and is rotatably disposed in the cylindrical body 28 via bearings 32a and 32b. The upper steering shaft 30 is formed in a hollow shape having a multistage outer peripheral shape, and a spline hole 34 is formed along a substantially intermediate position from the other end side where the diameter is increased.

  A spline shaft 36 is engaged with the spline hole 34. One end of the spline shaft 36 is rotatably supported with respect to the column 26 via a bearing 32 c and is connected to the lower steering shaft 40 via a universal joint 38. The lower steering shaft 40 is connected to a gear box assembly side (not shown).

  On the other hand, the steering wheel displacement mechanism 22 guides the movement direction of the steering wheel 16 in the axial direction of the steering wheel 16 (the axial direction of the spline shaft 36), and the movement drive unit 42 that moves and drives the steering wheel 16 according to the vehicle speed. A telescopic direction guide unit 44 (see FIG. 4) and a tilt direction guide unit 46 (see FIG. 4) for guiding the moving direction of the steering wheel 16 in the tilt direction of the steering wheel 16 (the direction in which the tilt angle with respect to the vertical direction of the steering wheel 16 is changed). 5). Here, the vertical direction refers to a direction extending in the vertical direction from the floor surface 13 of the vehicle 12, and the same applies hereinafter.

  The movement drive unit 42 is formed on the outer periphery of the column 26 over a predetermined length, and corresponds to the opening 48 of the column 26 and the opening 48 constituting one of the telescopic direction guides 44 described above. And a casing 50 attached thereto.

  Further, the movement drive unit 42 includes a motor 52 fixed in the casing 50, a worm gear 54 fixed to the rotating shaft 52 a of the motor 52, a worm wheel 56 meshed with the worm gear 54, and a coaxial with the worm wheel 56. The ball screw 58 is provided, and the nut 60 is engaged with the ball screw 58. The worm wheel 56 and the ball screw 58 are rotatably supported integrally in the casing 50 via bearings 62a and 62b. The nut 60 is fixed to the outer peripheral portion of the cylindrical body 28 and is disposed corresponding to the opening 48 of the column 26.

  As shown in FIG. 4, the telescopic direction guide portion 44 includes an opening 48 provided on the outer peripheral portion of the column 26 described above, a pair of protrusions 64 provided on the outer peripheral portion of the cylindrical body 28, and an outer periphery of the column 26. Among the portions, the first protrusions 66 are provided at positions corresponding to the pair of protrusions 64, and the pair of first long holes 66 are inserted through the pair of protrusions 64. The first long hole 66 is formed to extend along the axial direction of the spline shaft 36, and the length thereof is substantially the same as the length of the opening 48 (the length along the axial direction of the spline shaft 36). It is said that. For example, screwing or the like can be used for installing the pair of protrusions 64 on the cylindrical body 28.

  As shown in FIG. 5, the tilt direction guide portion 46 includes a pair of side plates 68 installed so as to sandwich a portion of the outer periphery of the column 26 where the movement drive unit 42 is not provided from both sides, and a pair of side plates. 68, and a pair of second long holes 70 through which the pair of protrusions 64 inserted through the first long holes 66 of the column 26 are inserted. The second long hole 70 has a curved portion 70 a formed so as to gradually go upward toward at least the steering wheel 16.

  Therefore, when the nut 60 of the movement drive unit 42 is located closer to the universal joint 38, the pair of protrusions 64 of the cylindrical body 28 are closer to one end of the first long hole 66, as shown in FIG. 6. As shown in FIG. 1, the steering wheel 16 is located at the farthest back as viewed from the driver's seat 14. At this time, the position where the driver 18 grips the steering wheel 16 is a position indicated by Pa and is a position away from the driver 18. This state is the initial state.

  When the nut 60 is moved closer to the driver's seat 14 by the movement drive by the movement drive unit 42 from the initial state, the pair of protrusions 64 of the cylindrical body 28 are connected to the first elongated hole 66 of the column 26 as shown in FIGS. And the other end of the first slot 66 and the other end of the second slot 70 (the end on the near side as viewed from the driver's seat 14) while being guided by the second slot 70 of the side plate 68. Move. As a result, the steering wheel 16 moves toward the driver's seat 14. Then, from the stage where the pair of protrusions 64 reaches the curved portion 70a of the second long hole 70, the cylinder body 28 is inclined so that the inclination angle of the axis of the cylinder body 28 with respect to the vertical direction becomes small, and accordingly, the steering As shown in FIG. 1, the wheel 16 approaches the driver's seat 14 and moves upward so that the inclination angle θ with respect to the vertical direction increases. When the nut 60 of the movement drive unit 42 is located closest to the driver's seat 14, or when the pair of protrusions 64 reaches the other end of the first long hole 66, or the pair of protrusions 64 is the second long hole. When the other end of 70 is reached, the movement of the steering wheel 16 is stopped. As a result, as shown in FIG. 1, the position at which the driver 18 grips the steering wheel 16 is the position indicated by Pb, which is the position closest to the driver 18.

  Contrary to the above, when the nut 60 of the movement drive unit 42 moves from the position close to the driver seat 14 to the position close to the universal joint 38, the steering wheel 16 moves away from the driver seat 14 and also in the vertical direction. It moves downward (initial state) so that the inclination angle θ decreases.

  Further, as shown in FIG. 2, the steering device 10 includes a vehicle speed sensor 72 for detecting the speed (vehicle speed) of the vehicle 12, and an axial movement distance of the steering wheel 16 (the cylinder 28 or the upper steering shaft 30. And a stroke sensor 74 for detecting an axial movement distance (stroke amount).

  Detection signals from the vehicle speed sensor 72 and the stroke sensor 74 are input to the control unit 76 (control unit). The control unit 76 is activated when the vehicle is activated, and drives and controls the motor 52 according to the detection signal.

  The operation of the steering apparatus 10 configured as described above will be described below.

  First, the relationship between the vehicle speed and the stroke amount of the steering wheel 16 and the relationship between the vehicle speed and the inclination angle θ with respect to the vertical direction of the steering wheel 16 are calculated by, for example, a control map shown in FIG. This control map is stored in a memory installed in the control unit 76 or an external memory accessed by the control unit 76.

  In the control map of FIG. 9, the stroke amount is defined as an amount that increases as the steering wheel 16 moves toward the driver's seat 14 with the initial state described above being zero. Accordingly, the vehicle speed is the maximum value (maximum stroke amount Lm) when the vehicle speed is 0, the vehicle speed decreases nonlinearly from 0 toward the predetermined speed va, and the vehicle speed is increased from the predetermined speed va to the preset high speed vb. It decreases linearly as it increases toward. When the vehicle speed is higher than the high speed vb, the stroke amount = 0 is set. In other words, the relationship between the vehicle speed and the stroke amount of the steering wheel 16 shows a non-linear change below the predetermined vehicle speed va, and shows a linear change above the predetermined vehicle speed va. Note that the predetermined speed va can be appropriately selected according to the size of the vehicle 12 or the like within the range of 30 to 40 km / h. The high speed vb can be selected as appropriate depending on the speed performance of the vehicle 12 or the like in the range of 80 to 100 km / h. The maximum stroke amount Lm can be selected as appropriate depending on the size of the vehicle 12 or the like in the range of 4 to 10 cm.

  In the control map of FIG. 9, the inclination angle θ is the maximum inclination angle θ2 (upward) when the vehicle speed is 0, the vehicle speed decreases nonlinearly from 0 toward the predetermined speed va, and the vehicle speed is It decreases linearly as it increases from a predetermined speed va. That is, the relationship between the vehicle speed and the inclination angle θ with respect to the vertical direction of the steering wheel 16 also shows a non-linear change below a predetermined vehicle speed va, and shows a linear change above the predetermined vehicle speed va. It should be noted that the maximum inclination angle θ2 can be selected as appropriate depending on the size of the vehicle 12 or the like within the range of + 3 ° to + 7 ° from the minimum inclination angle θ1 (a value fixed by the vehicle). . However, the inclination angle θ is reference information. This is because in the above-described configuration, the inclination angle θ is governed by the shape of the second long hole 70 provided in the pair of side plates 68. However, it is possible to easily process the second long hole 70 based on the control map by calculating the optimum relationship of the change in the inclination angle θ with respect to the vehicle speed in advance by simulation or actual vehicle experiment and recording it in the control map. It becomes possible. That is, the second long hole 70 may be processed so as to satisfy the change in the inclination angle θ with respect to the vehicle speed recorded in the control map.

  And in the initial state which started the vehicle 12, as mentioned above, the steering wheel 16 is located in the back | inner side. At this time, since the vehicle speed is 0, the control unit 76, when receiving the information of vehicle speed = 0, sets the stroke amount to the maximum stroke amount Lm based on the information of the control map, and based on this set value. The movement drive unit 42 is controlled so that the nut 60 is positioned closer to the driver seat 14. As shown in FIG. 1, the steering wheel 16 approaches the driver's seat 14 and moves upward so that the inclination angle θ with respect to the vertical direction increases in conjunction with the driver's seat 14. As a result, the position at which the driver 18 grips the steering wheel 16 is the position indicated by Pb in FIG. 1 and is closer to the driver 18 side, so that the steering wheel 16 can be easily and quickly rotated.

  When the vehicle starts to travel based on the start command of the vehicle 12 by the driver 18, the stroke amount of the steering wheel 16 gradually decreases (moves gradually toward the back as viewed from the driver's seat 14). At this time, in the low speed range until the vehicle speed reaches the predetermined vehicle speed va, the stroke amount gradually decreases non-linearly, so the position where the steering wheel 16 is gripped is almost close to the position indicated by Pb in FIG. The steering wheel 16 is still in the position, and the steering wheel 16 can be easily and quickly rotated, so that the switching operation when the vehicle 12 is taken out from the garage, traveling at a low-speed corner, and the like can be easily performed.

  When the vehicle speed increases and becomes equal to or higher than the predetermined vehicle speed va, the stroke amount of the steering wheel 16 further decreases. At this time, the stroke amount decreases linearly in a high speed range where the vehicle speed is equal to or higher than the predetermined vehicle speed va. Therefore, the steering wheel 16 moves away from the driver's seat 14 and moves downward so that the inclination angle with respect to the vertical direction becomes small in conjunction with the steering wheel 16. As a result, the position at which the steering wheel 16 is gripped moves toward the position indicated by Pa in FIG. 1 (the position in the initial state) and is further away from the driver 18, so the steering wheel 16 is rotated in small increments. It becomes easy to do. As a result, it is possible to improve the operability of the steering wheel 16 at a high speed, such as when traveling on a highway or traveling straight on a road with a good view. Further, since the steering wheel 16 moves away from the driver 18, the viewpoint of the driver 18 becomes farther, so that safety during driving is also improved.

  And if the speed of the vehicle 12 is reduced by entering a corner or a parking lot, the stroke amount of the steering wheel 16 increases again, and accordingly, the inclination angle θ of the steering wheel 16 with respect to the vertical direction also increases. Therefore, the position at which the steering wheel 16 is gripped approaches the position indicated by Pb in FIG. 1 and the steering wheel 16 can be easily rotated large and quickly, traveling at a low-speed corner, switching operation for parking, etc. Becomes easier.

  As described above, the steering device 10 according to the present embodiment can bring the steering wheel 16 closer to the driver 18 in the low speed range where the amount of operation with respect to the steering wheel 16 is expected to increase. The operability of the steering wheel 16 can be improved. On the other hand, in a high speed range where the amount of operation on the steering wheel 16 is expected to decrease, the steering wheel 16 can be moved away from the driver 18 side, and the operability of the steering wheel 16 at high speed can be improved. it can. That is, it is possible to improve the operability of the steering wheel 16 when the vehicle 12 is traveling.

  Further, in the present embodiment, a pair of second long holes 70 through which the pair of protrusions 64 of the cylindrical body 28 are inserted are provided in the pair of side plates 68 installed so as to sandwich the outer peripheral portion of the column 26 from both sides. Since the curved portion 70a is provided in the second long hole 70, the steering wheel 16 can be operated in conjunction with the movement of the steering wheel 16 in the axial direction with a simple configuration without providing a separate motor or actuator. It can be moved in the vertical direction, which is advantageous in reducing the size of the apparatus and reducing the cost.

  Of course, a separate motor or actuator may be installed to provide a mechanism for moving the cylinder 28 and the like up and down together with the movement drive unit. In this case, it is preferable to control the motor, the actuator, and the like based on the relationship between the vehicle speed in the control map and the tilt angle with respect to the vertical direction of the steering wheel. If a separate motor or actuator is installed, the mechanism (moving drive unit 42) for moving the steering wheel 16 in the axial direction is omitted, and only the inclination angle θ with respect to the vertical direction of the steering wheel is changed according to the vehicle speed. Also good.

  In the above-described example, the telescopic direction guide unit 44 and the tilt direction guide unit 46 are installed so that the steering wheel 16 is moved in the axial direction according to the vehicle speed, and the inclination angle θ of the steering wheel 16 with respect to the vertical direction is changed. However, the tilt direction guide 46 may be omitted and the steering wheel 16 may be moved only in the axial direction according to the vehicle speed.

  In addition to the above-described configuration, the following configuration may be employed. That is, as shown in FIG. 10, a first operation switch 78 and a second operation switch 80 that are disposed in the vehicle interior in the vicinity of the steering wheel 16 are provided.

  The first operation switch 78 has a function of selecting the type of movement of the steering wheel 16 by operating the dial 82. For example, if the dial display “tilt / telescopic” is selected, the steering wheel 16 is set to move in the axial direction and the inclination angle θ with respect to the vertical direction is changed according to the vehicle speed, and the dial display “telescopic” is selected. For example, only the function to move the steering wheel in the axial direction according to the vehicle speed is set. If the dial display “tilt” is selected, only the function to change the tilt angle θ with respect to the vertical direction of the steering wheel is set according to the vehicle speed. If the dial display “none” is selected, the movement of the steering wheel 16 can be restricted. The control unit 76 controls the steering wheel displacement mechanism 22 according to the selection of the first operation switch 78.

  The second operation switch 80 has a function of adjusting the stroke amount (or the inclination angle θ) of the steering wheel 16 by operating the dial 84 to control the rotation speed of the motor 52.

  For example, when telescopic or tilt / telescopic is selected by the first operation switch 78, the dial display “2” is set as a standard, and the magnitude of the stroke amount is set by the magnitude of the number. This setting is set based on the control map shown in FIG. Specifically, if the dial display “2” is selected, the standard second maximum stroke amount Lm2 is set, and if the dial display “1” is selected, the first maximum stroke that is lower than the second maximum stroke amount Lm2. If the amount Lm1 is set and the dial display “3” is selected, the third maximum stroke amount Lm3 higher than the standard second maximum stroke amount Lm2 is set.

  When tilt or tilt / telescopic is selected by the first operation switch 78, the dial display “2” is set as a standard, and the magnitude of the tilt angle θ is set by the magnitude of the number. Similarly to the above, if the dial display “2” is selected, the standard second maximum inclination angle θ2b is set, and if the dial display “1” is selected, the first smaller than the standard second maximum inclination angle θ2b is set. If the maximum inclination angle θ2a is set and the dial display “3” is selected, a third maximum inclination angle θ2c larger than the standard second maximum inclination angle θ2b is set.

  Therefore, when the driver 18 operates the steering wheel 16 and determines that the variable control of the position of the steering wheel 16 according to the vehicle speed is unnecessary, the first operation switch 78 is operated to display the dial 82 on the dial display. It can be adjusted to “none”. Further, if the variable control of the position of the steering wheel 16 according to the vehicle speed is to be the stroke only, the first operation switch 78 may be operated to match the dial display “Telesco”, and the variable control of the position of the steering wheel 16 is tilted. If only the angle θ is desired, the first operation switch 78 may be operated to match the dial display “tilt”. Of course, if the variable control of the position of the steering wheel 16 is to be set to stroke and tilt, the first operation switch 78 may be operated to match the dial display “tilt / telescopic”.

  When “Telesco”, “Tilt” or “Tilt / Telesco” is selected by the first operation switch 78, the dial 84 of the second operation switch 80 is set to any dial display “1” to “3”. By setting to the position, the effect that the maximum stroke amount and the maximum inclination angle of the steering wheel 16 can be easily adjusted according to the preference of the driver 18 is obtained.

  In addition, the steering device according to the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted without departing from the gist of the present invention.
