Handle control system having portable force feedback function

Abstract

To solve the problem that a handle controller having a force feedback function in a market requires an installation space since it is an installation type having a handle of the size equal to that of an actual object when driving a vehicle in a home-use game, and contrarily a portable handle controller having a force feedback function that does not require any installation space differs from a loaded vehicle in terms of execution of acceleration and brake operation by using a joystick and a drive operation feeling since it is via a deceleration mechanism using a gear.SOLUTION: There is provided a handle control system which provides to a player, a more real drive operation feeling, by connecting an acceleration pedal and a brake pedal to a controller body as separate units for each of them by radio and directly driving a handle by a brushless motor in a portable handle controller having a force feedback function.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] The present invention relates to a portable steering wheel control system with a force feedback function for providing a realistic driving feel when driving a vehicle in a home video game. [Background technology]

[0002] Patent Document 1 presents a portable controller that generates a reaction force on the steering wheel when driving a vehicle in a home video game. This provides the game player with a realistic steering feel by feeding back to the controller's steering wheel the reaction force generated according to the angle at which the steering wheel is turned and the vehicle speed in a real vehicle, as well as the reaction force caused by unevenness in the road surface.

[0003] The portable controller presented in Patent Document 1 operates the accelerator and brake with a joystick built into the controller body, and also uses a DC motor to generate force feedback, transmitting the reaction force to the handle via a reduction mechanism.

[0004] [Patent Document 1] Patent application 2023-162329 Summary of the Invention [Problem to be solved by the invention]

[0005] The portable steering wheel controller with force feedback function presented in Patent Document 1 operates the accelerator and brake with a joystick built into the controller, which is different from the way an actual car is driven. In addition, because there is a gear reduction mechanism between the DC motor for force feedback and the steering wheel, a time gap occurs when the force is reversed from positive to negative due to gear backlash. For these reasons, the driving operation feel is different from that of an actual car.

[0006] An object of the present invention is to provide a steering wheel control system which is portable and yet provides a driving feel similar to that of an actual car. [Means for solving the problem]

[0007] The present invention has been made to solve the above-mentioned problems, and provides a steering wheel control system in which the accelerator pedal and brake pedal are made into separate portable units in a portable game controller with a force feedback function, and the reaction force when operating the steering wheel is transmitted directly without going through a reduction mechanism. Effect of the Invention

[0008] According to the present invention, no space is required to install a controller. In addition, the layout can be freely set to either step on the brake pedal with the right foot or the left foot. Furthermore, the reaction force to the steering wheel is transmitted directly from the motor. As a result, the player can get a realistic driving feel. [Brief description of the drawings]

[0010] The system is configured with a controller body with a steering wheel and switches, and a pedal unit with an accelerator pedal and brake pedal wirelessly connected. The brushless motor that generates the force feedback is directly connected to the steering wheel without going through a reduction mechanism. EXAMPLES

[0011] FIG. 1 is a diagram showing the system configuration according to an embodiment of the present invention.

[0012] FIG. 2 is a perspective view of the appearance of the controller according to the embodiment of the present invention.

[0013] 3 is a plan view of the controller of the embodiment of the present invention. In addition to the handle 2, it is equipped with switches 3 to 6 for allocating functions such as upshifting, downshifting, clutch, and handbrake. The number of switches may be further increased.

[0014] FIG. 4 is a cross-sectional view of the internal structure of the controller body of the present invention. The handle 2 is attached to the outer rotor of the brushless motor 7. A shaft 8 is fixed to the rotating shaft of the outer rotor, and a magnet 9 for an encoder is attached to the opposite pole of the shaft 8 from the handle 2. A rotary encoder sensor 10 is disposed behind the magnet 9. This allows the angle of the handle 2 to be read by the rotary encoder sensor 10. By passing a current in the opposite direction to the rotation of the brushless motor 7, the player can feel a reaction force. In this case, even if the brushless motor 7 rotates with maximum torque, the torque is set to a level that the player can stop the rotation by pressing the handle 2 with his or her fingers.

[0015] In this embodiment, the angle detection element of the handle 2 is a magnetic encoder, but it may be an optical encoder.

[0016] 5 is a perspective view of the pedal unit 12. When the pedal is depressed, an internal potentiometer rotates, making it possible to detect the amount of depression.
