[0003] The present disclosure relates to a steering and driving interface device for a vehicle. Background Art

[0004] As autonomous vehicle technology advances, there is a need for steering and driving human-machine interfaces (HMIs) that are suitable for autonomous driving environments. In this context, it is necessary to ensure driving safety and reduce workload by developing steering and driving HMIs that meet the needs of drivers.

[0005] Space innovation in future vehicle design involves moving the driver's seat toward the rear of the vehicle, thereby significantly expanding the space in front of the driver. As the space in front of the driver increases, the distance between the driver's feet and the pedals increases, making it impossible to smoothly use the pedals to accelerate or decelerate the vehicle.

[0006] Therefore, research is ongoing to develop new interfaces by modifying integral elements of existing designs and changing the shape and location of steering and drive devices. Summary of the invention

[0007] The present disclosure attempts to improve the regulatory performance of the autonomous driving human-machine interface so that the interface can be used easily and quickly even in dangerous situations.

[0046] Figure 1 is a perspective view showing a steering and driving interface device for a vehicle according to an embodiment.

[0047] See also Figure 1 The steering and driving interface device 100 for a vehicle according to the present embodiment is a device installed in a vehicle. The device includes a track portion 51 fixed in the vehicle and a driving portion 50 configured to control acceleration and deceleration of the vehicle (see Figure 2 The driving device further includes a steering unit 70 configured to control the rotation direction of the vehicle (see Figure 4 ) and an operating lever 30 configured to operate the driving portion 50 and the steering portion 70.

[0048] The operating rod 30 may be coupled to the steering portion 70 and the driving portion 50 and extend upward (i.e., the Z-axis direction in the drawings). The operating rod 30 may control the acceleration and deceleration of the vehicle by operating the driving portion 50. The operating rod 30 may also control the rotation of the vehicle by operating the steering portion 70. The operating rod 30 may be provided in the form of a control lever.

[0049] The steering and driving interface device 100 for a vehicle may be arranged on an armrest of the vehicle. The track portion 51, the driving portion 50, and the steering portion 70 may be covered by the armrest outer cover 41. The operating rod 30 may reciprocate along the track portion 51. The armrest outer cover 41 may have an opening 410 extending in one direction along the moving path of the operating rod 30. The opening 410 of the armrest outer cover 41 is covered by a slit cover 43 having a slit 431 formed along the moving path of the operating rod 30. Therefore, the slit cover 43 may protect the track portion 51, the driving portion 50, and the steering portion 70 covered by the armrest outer cover 41 without hindering the movement of the operating rod 30.

[0050] In the following, reference is made to Figures 2 to 4 The detailed structures of the driving portion 50 and the steering portion 70 are described.

[0051] Figures 2 to 4 is the explanation Figure 1 A stereoscopic view of a driving portion and a steering portion of a steering and drive interface device for a vehicle is shown in FIG.

[0052] refer to Figure 2 and Figure 3 , the track portion 51 may be elongated in a first direction (x-axis direction in the drawing) in the vehicle. The driving portion 50 may be coupled to the track portion 51 so as to be movable in the first direction. The steering portion 70 may be disposed in the track portion 51 and rotate around a rotation axis parallel to the first direction.

[0053] The operating lever 30 may include an upper lever 31 and a lower lever 34. The upper lever 31 and the lower lever 34 are connected to each other by a hinge member 36. The upper lever 31 may be configured to be bendable in a first direction from the hinge member 36. Therefore, when the operating lever 30 is not operated, the hinge member 36 may be bent and the upper lever 31 may be lowered. A cylindrical pin 37 may be applied to the hinge member 36 to fix the upper lever 31 when the upper lever 31 is standing.

[0054] The upper rod 31 may have a U-shape in which a pair of bars 31a and 31b extending upward meet together at their lower ends and are connected to each other when the operating lever 30 is operated. One end of the lower rod 34 may be connected to the lower end of the upper rod 31, and the other end of the lower rod 34 may be coupled to the steering portion 70. The lower end of the upper rod 31 and the upper end of the lower rod 34 connected by the hinge member 36 may be surrounded by a protective tube (not shown). The protective tube may be provided in the form of a bellows provided outside the upper rod 31 and the lower rod 34.

[0055] The driving part 50 includes a slider 53 and a slide sensing part 55 configured to sense movement of the slider 53. The slider 53 may be coupled to the rail part 51 and reciprocate in a first direction. The slide sensing part 55 may be disposed on the slider 53 and configured to sense movement of the slider 53.

[0056] The slide sensing portion 55 may include a slide sensing bracket 551 disposed at the upper end of the rail portion 51 and a slide sensing wheel 552 disposed on the slider 53. The slide sensing wheel 552 may be configured to rotate by movement of the slider 53 while in contact with the slide sensing bracket 551.

[0057] The rail portion 51 may include support ends 511 and 512 extending from the upper end of the rail portion 51 in a direction in which the support ends 511 and 512 face each other. The slider 53 may have a sliding support pin 57 provided on a portion of the lower surface facing the support ends 511 and 512. The sliding support pin 57 may roll while supporting the lower surfaces of the support ends 511 and 512, so that the slider 53 may move smoothly.

[0058] See also Figure 4 , the driving portion 50 includes a sliding auxiliary portion 60 configured to generate and provide a driving force for moving the slider 53. The sliding auxiliary portion 60 may include a sliding worm gear 63 fixed to the slider 53, a sliding gear 62 fixed to the rail portion 51, and a sliding motor 61 having a driving shaft. The sliding gear 62 may be coupled (e.g., gear-coupled) to the sliding worm gear 63. The rotating shaft of the sliding gear 62 may be coupled to the driving shaft of the sliding motor 61. The sliding motor 61 may be fixed to the rail portion 51. Therefore, the slider 53 may be stably operated with the assistance of the sliding motor 61.

[0059] The sliding worm wheel 63 may be fixed to the sliding worm 64, and the sliding worm 64 may be fixed to one end of the rail portion 51 with the support bearing 65 interposed therebetween. Therefore, the sliding worm wheel 63 may rotate in a state where the sliding worm wheel 63 is supported by the rail portion 51.

[0060] The steering portion 70 may be disposed in the slider 53. One end of the operating rod 30 may be coupled to the steering rotation shaft 71 of the steering portion 70, and the other end of the operating rod 30 may protrude upward from the slider 53. The slider 53 may have a slit 534 formed in an upper surface of the slider 53 through which the operating rod 30 protrudes. The slit 534 extends in a second direction (y-axis direction in the drawing) intersecting the first direction.

[0061] See also Figure 4The steering portion 70 may include a steering torque angle sensor 73 connected to the steering rotation shaft 71 and configured to detect the rotation torque. The steering portion 70 may include a steering assist portion 80 configured to allow the operating lever 30 to rotate smoothly. The steering assist portion 80 may include a steering worm gear 83 fixed to the steering rotation shaft 71 and a steering motor 81 having a drive shaft coupled (e.g., gear coupled) to the steering worm gear 83. The steering motor 81 may be fixed to the slider 53.

[0062] When the driver rotates the operating lever 30 to the left or right, the steering torque angle sensor 73 detects the torque, and the steering motor 81 assists the rotational force of the operating lever 30 .

[0063] Figure 5 and Figure 6 Explanation operation Figure 1 A perspective view of a method for a steering and drive interface device for a vehicle is shown in FIG.

[0064] Reference Figure 5 , the driver can grip the operating lever 30 and operate the operating lever 30 forward or backward in a first direction (the x-axis direction in the drawing). In this case, the driving portion 50 (see FIG. 2 ) connected to the operating lever 30 Figure 3 ) can accelerate or decelerate the vehicle.

[0065] In addition, the driver can also grasp the operating lever 30 and operate the operating lever 30 to the left or right in the second direction (the y-axis direction in the drawing). In this case, the steering portion 70 (see FIG. 2 ) connected to the operating lever 30 is Figure 4 ) can turn the vehicle left or right.

[0066] Since the upper rod portion 31 of the operating rod 30 has a U-shape extending upward, the driver can conveniently hold the upper rod portion 31 with his / her hand and easily control the vehicle.

[0067] refer to Figure 6 When the driver does not use the operating lever 30, the driver folds the hinge member 36 and lowers the upper rod portion 31 of the operating lever 30 in the first direction. The hinge member 36 can be folded automatically or manually, so that the space for the driver can be further ensured in the vehicle.

[0068] The steering and driving interface device 100 for a vehicle can be accommodated in the vehicle in the case of automatic driving. For example, when the steering and driving interface device 100 for a vehicle is not used, the steering and driving interface device 100 can be positioned in the armrest portion at the right side of the driver's seat. When the accommodation box (not shown) is opened, the hardware part (not shown) can be moved upward and exposed in a pop-up manner as needed. In this case, the U-shaped operating lever 30 can also be fallen down, allowing the driver to pull and unfold the operating lever 30 to use the operating lever 30.

[0069] When it is determined that the vehicle cannot drive automatically, the steering and driving interface device 100 for the vehicle may switch the driving mode from automatic driving to manual driving and issue an alarm. When the autonomous driving system fails because the vehicle cannot recognize the surrounding environment due to unexpected circumstances (such as system errors, sensor damage, and bad weather), it may be determined that autonomous driving cannot be performed. After the determination, the main processing device of the vehicle takes over the control, and after the hardware part is exposed, the control may be taken over manually. The alarm may include a visual notification through a display mounted on the front side of the vehicle and an auditory notification of the sound system.

[0070] Figure 7 is a block diagram explaining a steering logic of a controller for a steering and driving interface device of a vehicle according to an embodiment. Figure 8 is a block diagram explaining a driving / control logic of a controller for a steering and driving interface device of a vehicle according to an embodiment.

[0071] The steering and driving interface device 100 for a vehicle according to the present embodiment includes controllers 120 and 150 configured to generate a command for operating the vehicle by receiving a driving signal according to the movement of the operating lever 30. In this case, the steering and driving interface device 100 may include the controller 120 for steering logic and the controller 150 for driving / braking logic.

[0072] refer to Figure 7 The controller 120 may include a steering angle instruction generating unit 121 configured to generate a steering angle instruction. The controller 120 may also include a wheel actuator control unit 123 configured to rotate the wheel 130. The steering angle instruction generating unit 121 may receive a steering torque angle sensor 73 (see FIG. 1 ) from the steering unit 70. Figure 4 ) to generate a steering angle command. The steering angle command generating unit 121 can generate a torque-based steering angle command by applying a steering torque, a vehicle speed, a vehicle yaw rate, etc. The running wheel actuator control unit 123 can rotate the running wheel 130 by receiving the steering angle command.

[0073] In addition, the controller 120 may include an operation lever position control unit 125 configured to receive feedback of the steering angle value of the running wheel 130 and transmit a command to the steering unit 70. When the steering angle value of the running wheel 130 is input to the steering motor 81 of the steering assist unit 80, a steering assist function may be performed.

[0074] refer to Figure 8 The controller 150 may include a speed command generating unit 151 configured to generate a vehicle speed command and a vehicle speed control unit 153 configured to control the vehicle speed. The speed command generating unit 151 may generate the vehicle speed command by receiving the sliding stroke measured by the driving unit 50 .

[0075] When connected to the sliding sensing bracket 551 (see Figure 2 ) of the sliding sensing wheel 552 (see Figure 2 ) rotates, the stroke can be calculated by reading the angle value at the position of the sliding sensing wheel 552 and converting the angle value. When the slider 53 (see Figure 2 ), the vehicle starts to move, and the speed increases. When the slider 53 is pulled backward, the vehicle speed decreases, and the vehicle eventually stops.

[0076] The vehicle speed control portion 153 may operate the vehicle 160 by receiving information such as the sliding stroke and the vehicle speed and may control the vehicle speed.

[0077] The controller 150 may include an operating lever motor control unit 155 configured to receive feedback of the speed of the vehicle 160 and transmit a command to the drive unit 50. The vehicle speed and the like may be fed back to the slide motor 61 (see FIG. Figure 3 ), and can perform sliding assistance functions.

[0078] Fig. 9 is the explanation Figure 1 A view of the location where a steering and drive interface device for a vehicle is arranged in a vehicle is shown in FIG.

[0079] See also Fig. 9 The steering and driving interface device 100 for a vehicle according to the present embodiment may be provided on the armrest 15 in the vehicle. Even when the seat is moved backward, the driver may operate the steering and driving interface device 100 for the vehicle to control the steering, acceleration and deceleration of the vehicle.

[0080] In addition, with the steering and driving interface device 100 for a vehicle, the accelerator pedal function and the steering function of a vehicle in the related art are combined at one location, so that the steering wheel and the pedals can be removed. Therefore, it is possible to reduce the space occupied by components in the vehicle and increase the space that can be used by the occupants. In addition, the steering and driving interface device 100 for a vehicle can stably operate the acceleration and deceleration of the vehicle even under high-speed turning conditions.

[0081] As another embodiment, the steering and driving interface device 100 ′ for a vehicle may be disposed inside a vehicle door located on the left side of the driver.

[0082] According to the steering and driving interface device for a vehicle of the described embodiment, the driver's space utilization can be maximized by removing the steering wheel, accelerator pedal and brake pedal from the autonomous vehicle. Therefore, the space utilization of the driver in the driver's seat can be improved in many aspects.

[0083] In the case where space utilization in a vehicle is improved, an armrest needs to be provided. The armrest allows the driver to rest his arms by placing the seat in an inclined manner and resting his arms on the armrest. The steering and driving interface device for a vehicle of the present embodiment can be added by effectively utilizing the armrest space.

[0084] In the case where the seat is pushed backward during autonomous driving, in the related art, it is difficult for the driver's body to reach the steering wheel and pedals. However, in the case where the steering and driving interface device for the vehicle is provided near the armrest, the convenience can be improved.

[0085] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited thereto. Various modifications can be made and implemented within the scope of the claims, the detailed description of the present disclosure, the drawings, and the present disclosure.
