An autonomous vehicle is a smart vehicle to which autonomous driving technology enabling the vehicle to move to a destination in the state in which a driver does not directly manipulate a steering wheel, an accelerator pedal, and a brake is applied.
In the case in which an autonomous driving situation is generally realized, it is possible to switch between a manual driving mode, in which a driver directly drives a vehicle, and an autonomous driving mode, in which a vehicle moves to a destination while a driver does not directly drive the vehicle.
Meanwhile, when an emergency situation occurs during autonomous driving, any one of passengers in a vehicle must directly manually manipulate the vehicle. To this end, the vehicle is provided with an apparatus configured to be manipulated by a user in the manual driving mode.
For example, a vehicle manager may manipulate a vehicle in the manual driving mode using a device used in a game console, such as a joystick.

As shown in
The integrated manipulation apparatus 10 in some forms of the present disclosure is a portable manipulation apparatus that a user can move to a desired position while holding the apparatus in their hands. The integrated manipulation apparatus 10 may be connected to a controller of the autonomous vehicle via a wire to transmit a signal, or may be configured to transmit a signal using wireless communication. The integrated manipulation apparatus 10 is easy to manipulate, since the apparatus is small and light.
That is, the integrated manipulation apparatus 10 in some forms of the present disclosure includes a housing 100 configured to be held by a user in both hands, a chassis function switch 200 provided at the housing 100, the chassis function switch 200 being configured to be manipulated by the user in order to perform steering, speed change, acceleration, and braking, a general function switch 300 provided at the housing 100, the general function switch 300 being configured to be manipulated by the user in order to perform lamp on/off, honking, and turn indication, a display 400 provided at the housing 100, the display 400 being configured to visually display information about a manipulated switch, and a deadman switch 500 provided at the housing 100, the deadman switch 500 being configured to be manipulated by the user.
The deadman switch 500 is a switch that the user manipulates to perform steering, speed change, acceleration, and braking when the chassis function switch 200 is manipulated. Only when the user manipulates the chassis function switch 200 in the state in which the deadman switch 500 is manipulated, a function of the manipulated chassis function switch 200 is performed.
When the user manipulates the chassis function switch 200 in the state in which the deadman switch 500 is not manipulated, the function of the manipulated chassis function switch 200 is not performed. At this time, a warning alarm (text or figure) is provided to the user through the display 400.
That is, a function corresponding to each of steering, speed change, acceleration, and braking of the vehicle is a main factor that is connected directly with passenger safety. In consideration of safety of the passenger, the chassis function switch 200 is manipulated only in the state in which the deadman switch 500 is manipulated.
When the user manipulates the general function switch 300, on the other hand, the function of the manipulated general function switch 300 is immediately performed irrespective of whether the deadman switch 500 is manipulated.
That is, a function corresponding to each of lamp on/off, honking, and turn indication of the vehicle is a subsidiary factor that is not connected directly with safety of the passenger. When the user manipulates the general function switch 300 in the state in which the deadman switch 500 is manipulated, the function of the manipulated general function switch 300 is immediately performed. In addition, when the user manipulates the general function switch 300 in the state in which the deadman switch 500 is not manipulated, the function of the manipulated general function switch 300 is also immediately performed.
The housing 100 of the integrated manipulation apparatus 10 in some forms of the present disclosure includes a first grip portion 110 configured to be held by the user in one hand, a second grip portion 120 configured to be held by the user in the other hand, the second grip portion 120 being spaced apart from the first grip portion 110, and a switch portion 130 configured to interconnect the first grip portion 110 and the second grip portion 120, the chassis function switch 200, the general function switch 300, the display 400, and the deadman switch 500 being provided at the switch portion 130.
When describing the case in which the user is a right-handed person by way of example, the user may hold the first grip portion 110 in the right hand and may hold the second grip portion 120 in the left hand.
The chassis function switch 200 in some forms of the present disclosure includes a steering dial switch 210 provided at the upper surface of the switch portion 130 in front of the first grip portion 110, the steering dial switch 210 being configured to be manipulated by the user through rotation using a finger, an acceleration button switch 220 and a braking button switch 230 provided at the upper surface of the switch portion 130 in front of the second grip portion 120, the acceleration button switch 220 and the braking button switch 230 being configured to be manipulated by the user through push using a finger, and a speed change slide switch 240 provided at the front surface of the switch portion 130, the speed change slide switch 240 being configured to be manipulated by the user through push or pull using a finger.
In the present disclosure, the steering dial switch 210, the acceleration button switch 220, and the speed change slide switch 240 are different in manipulation manner from each other in order to prevent unintentional manipulation. The acceleration button switch 220 and the braking button switch 230, which are buttons configured to be manipulated in order to accelerate and decelerate the vehicle, are identical in manipulation manner to each other in order to maintain consistency in manipulation. However, the acceleration button switch 220 and the braking button switch 230 may be different in manipulation manner from each other as needed.
The user may manipulate the steering dial switch 210 by rotating the steering dial switch 210 using all fingers of the right hand in the state of holding the second grip portion 120 in the left hand.
The steering dial switch 210 may be provided with a power handle 211 configured to allow the user to rotate the steering dial switch 210 using small force.
The upper surface of the power handle 211 is formed so as to be concave such that the user puts a finger thereon. When the user puts the thumb or the index finger of the right hand on the upper surface of the power handle 211 and applies small rotational force thereto, the entirety of the steering dial switch 210 may be rotated relative to the housing 100.
A permanent magnet 220 is coupled to the steering dial switch 210. The permanent magnet 220 is installed so as to face a printed circuit board (PCB) 600 fixed to the housing 100. When the user rotates the steering dial switch 210, therefore, the position of the permanent magnet 220 is changed, and the PCB 600 generates a signal related to steering through a change in magnetic flux based on a change in position of the permanent magnet 220.
The steering dial switch 210 is rotated in the clockwise direction or in the counterclockwise direction relative to the housing 100 when manipulated by the user. When user manipulation force is released, the steering dial switch 210 is rotated in the opposite direction to return to the initial position thereof by spring force of a return spring 213.
In addition, a damper 214 is engaged with the steering dial switch 210 in the form of an external gear. The damper 214 serves to reduce the return speed of the steering dial switch 210 based on spring force to thus prevent noise and impact.
The acceleration button switch 220 and the braking button switch 230 are provided at the upper surface of the switch portion 130 in front of the second grip portion 120 in the state of being exposed upwards from the housing 100. The user manipulates the acceleration button switch 220 and the braking button switch 230 using the thumb of the left hand holding the second grip portion 120.
To this end, each of the acceleration button switch 220 and the braking button switch 230 is installed so as to be inclined at a predetermined angle in a longitudinal direction of the second grip portion 120 such that the acceleration button switch 220 and the braking button switch 230 can be easily manipulated using the thumb of the left hand of the user holding the second grip portion 120. Preferably, each of the acceleration button switch 220 and the braking button switch 230 is installed so as to be inclined at an angle of about 45 degrees such that the acceleration button switch 220 and the braking button switch 230 can be easily manipulated using the thumb of the left hand holding the second grip portion 120 in consideration of ergonomic characteristics. However, the present disclosure is not limited thereto.
In addition, the braking button switch 230 is located at the side of the acceleration button switch 220. Preferably, the acceleration button switch 220 and the braking button switch 230 are installed parallel to each other in consideration of ergonomic characteristics. However, the present disclosure is not limited thereto.
The acceleration button switch 220 and the braking button switch 230 may be different in width and length from each other in order to prevent unintentional manipulation.
That is, the portion of each of the acceleration button switch 220 and the braking button switch 230 that protrudes upwards from the housing 100 may be rectangular. In this case, the width of the acceleration button switch 220 may be less than the width of the braking button switch 230, and the length of the acceleration button switch 220 may be greater than the length of the braking button switch 230.
In the case in which the acceleration button switch 220 and the braking button switch 230 are configured so as to have different widths and lengths, as described above, intuition is improved and thus unintentional manipulation is prevented.
Also, in order to prevent unintentional manipulation of the user, an embossed surface 221 of the acceleration button switch 220 and an embossed surface 231 of the braking button switch 230 may be formed so as to be different from each other.
The acceleration button switch 220 and the braking button switch 230 are installed in the same construction. That is, the upper end of each of the acceleration button switch 220 and the braking button switch 230 is rotatably installed at the housing 100 via a rotary shaft, a return spring is wound around the rotary shaft, one end of the return spring is fixedly coupled to the housing 100, and the other end of the return spring is fixedly coupled to a corresponding one of the acceleration button switch 220 and the braking button switch 230.
Permanent magnets 222 and 232 are coupled to lower ends of the acceleration button switch 220 and the braking button switch 230 so as to face the PCB 600.
When the user pushes the upper surface of the acceleration button switch 220 or the braking button switch 230 using the thumb of the left hand holding the second grip portion 120, therefore, the acceleration button switch 220 or the braking button switch 230 is rotated about the rotary shaft, and the positions of the permanent magnets 222 and 232 are changed by rotation of the acceleration button switch 220 or the braking button switch 230. The PCB 600 recognizes rotation of the acceleration button switch 220 or the braking button switch 230 through a change in magnetic flux based on a change in position of the permanent magnets 222 and 232, and generates a signal related to acceleration or braking.
Each of the acceleration button switch 220 and the braking button switch 230 is a pedal type button switch having an upper end configured to be turnable relative to the housing about the rotary shaft.
The speed change slide switch 240 is provided at the front surface of the switch portion 130. The user may push or pull the speed change slide switch 240 in a leftward-rightward direction using the thumb or the index finger of the right hand in the state of holding the second grip portion 120 in the left hand in order to manipulate the speed change slide switch 240.
The speed change slide switch 240 is installed so as to be slidable relative to the housing 100 leftwards and rightwards. The speed change slide switch 240 is provided with a return spring. When user manipulation force is released, the speed change slide switch 240 returns to the neutral position thereof.
The speed change slide switch 240 is also provided with a permanent magnet 241. The permanent magnet 241 is installed so as to face the PCB 600. When the user pushes or pulls the speed change slide switch 240, the position of the permanent magnet 241 is changed. The PCB 600 recognizes movement of the speed change slide switch 240 through a change in magnetic flux based on a change in position of the permanent magnet 241, and generates a signal related to speed change.
The general function switch 300 in some forms of the present disclosure includes an emergency light switch 310 and a honking switch 320 provided at the upper surface of the switch portion 130 at the rear thereof so as to be spaced apart from each other in a leftward-rightward direction, a right turn signal switch 330 provided at the front surface of the switch portion 130 so as to be located in front of the steering dial switch 210, a left turn signal switch 340 provided at the front surface of the switch portion 130 so as to be located in front of the acceleration button switch 220 and the braking button switch 230, and a headlamp switch 350 and a fog lamp switch 360 provided at the rear surface of the switch portion 130 so as to be spaced apart from each other in the leftward-rightward direction.
Each of the emergency light switch 310, the honking switch 320, the right turn signal switch 330, the left turn signal switch 340, the headlamp switch 350, and the fog lamp switch 360 constituting the general function switch 300 is a tactile switch configured to be manipulated as the result of being pushed by a finger of the user. The tactile switch is a switch that is small, is easily returned to the initial position thereof by a rubber spring provided therein, and outputs a signal in a contact manner when manipulated.
The emergency light switch 310 and the honking switch 320, which are components of the general function switch that are frequently used, are located at the upper surface of the switch portion 130 at the rear of the display 400, and are located between the steering dial switch 210 and the acceleration button switch 220 and the braking button switch 230.
In the state in which the user manipulates the acceleration button switch 220, the braking button switch 230, or the deadman switch 500 using a finger of the left hand while holding the second grip portion 120 in the left hand, the user may take the right hand off the steering dial switch 210 and may then easily manipulate the emergency light switch 310 or the honking switch 320.
For reference, the autonomous vehicle drives at a low speed when the user manipulates the integrated manipulation apparatus 10. In the state in which the user manipulates the acceleration button switch 220, the braking button switch 230, or the deadman switch 500 using the finger of the left hand holding the second grip portion 120, therefore, the user may take the right hand off the steering dial switch 210 and may then manipulate the emergency light switch 310 or the honking switch 320 using the thumb or the index finger of the right hand.
The headlamp switch 350 and the fog lamp switch 360, which are components of the general function switch that are used under specific conditions, are located at the rear surface of the switch portion 130, which is minimally exposed to the user.
In the state in which the user manipulates the acceleration button switch 220, the braking button switch 230, or the deadman switch 500 using a finger of the left hand while holding the second grip portion 120 in the left hand, the user may take the right hand off the steering dial switch 210 and may then manipulate the emergency light switch 310 or the honking switch 320.
The right turn signal switch 330 and the left turn signal switch 340, which are components of the general function switch that are the most frequently used, are manipulated using the middle finger of the right hand and the middle finger of the left hand of the user, respectively.
The right turn signal switch 330 is configured to be manipulated using a finger of the right hand even in the state in which the user manipulates the steering dial switch 210 using the right hand. To this end, the right turn signal switch 330 is located at the front surface of the switch portion 130 in front of the steering dial switch 210.
The left turn signal switch 340 is configured to be manipulated using a finger of the left hand even in the state in which the user manipulates the acceleration button switch 220, the braking button switch 230, or the deadman switch 500 using the left hand. To this end, the left turn signal switch 340 is located at the front surface of the switch portion 130 in front of the acceleration button switch 220 and the braking button switch 230.
The deadman switch 500 is configured to be manipulated using the index finger or the middle finger of the left hand holding the second grip portion 120. To this end, the deadman switch 500 is located at the front surface of the switch portion 130 so as to be located in front of the acceleration button switch 220 and the braking button switch 230 while being located above the left turn signal switch 340.
In order to prevent unintentional manipulation of the left turn signal switch 340 and the deadman switch 500, the left turn signal switch 340 is installed so as to be inclined at a predetermined angle Al relative to the installation angle of the deadman switch 500.
That is, the deadman switch 500 is installed at the front surface of the switch portion 130 at the right angle in an upward-downward direction (a reference line Cl of
Also, in order to prevent unintentional manipulation by the user, an embossed surface 341 of the left turn signal switch 340 and an embossed surface 510 of the deadman switch 500 may be formed so as to be different from each other.
The display 400 is located at the upper surface of the switch portion 130 so as to be surrounded by the steering dial switch 210, the acceleration button switch 220, the emergency light switch 310, and the honking switch 320 such that the user can more easily visually recognize the display 400.
Hereinafter, a control method of the integrated manipulation apparatus 10 for autonomous vehicles in some forms of the present disclosure will be described.
The control method of the integrated manipulation apparatus 10 for autonomous vehicles in some forms of the present disclosure is characterized in that, only when a signal of the chassis function switch 200 is generated in the state in which a signal of the deadman switch 500 is generated, the PCB 600 processes the signal of the chassis function switch 200 such that the function of the manipulated chassis function switch 200 is performed.
In addition, when a signal of the chassis function switch 200 is generated in the state in which no signal of the deadman switch 500 is generated, the PCB 600 does not process the signal of the chassis function switch 200 and provides a warning alarm to the user through the display 400 such that the function of the manipulated chassis function switch 200 is not performed.
When a signal of the general function switch 300 is generated irrespective of whether a manipulation signal of the deadman switch 500 is generated, the PCB 600 immediately processes the signal of the general function switch 300 such that the function of the manipulated general function switch 300 is performed.
When a signal of the acceleration button switch 220 and a signal of the braking button switch 230 are simultaneously generated, the PCB 600 processes the signal of the braking button switch 230 earlier than the signal of the acceleration button switch 220 for safety of the passenger.
A chassis function directly connected with safety of the passenger is a braking function, rather than an acceleration function. In the case in which an acceleration signal and a braking signal are simultaneously generated, therefore, the PCB 600 processes the braking signal earlier than the acceleration signal in consideration of passenger safety.
When a signal of a transmission gear indicating that a driving direction of the vehicle is changed is generated in the state in which no signal of the braking button switch 230 is generated while the vehicle drives, the PCB 600 generates a signal for forcibly finishing driving of the vehicle and provides an alarm requesting the user to check the transmission gear through the display 400, whereby driving stability is secured.
Here, the signal of the transmission gear indicating that the driving direction of the vehicle is changed is an R-gear signal generated in the state in which the current transmission gear is D or a D-gear signal generated in the state in which the current transmission gear is R.
In some forms of the present disclosure described above, when the driving mode is switched from the autonomous driving mode to the manual driving mode, the user manipulates the integrated manipulation apparatus 10, which is portable, to perform chassis functions, such as steering, speed change, acceleration, and braking of the vehicle, and to perform general functions, such as lamp on/off, honking, and turn indication, as needed. The integrated manipulation apparatus is easy and convenient to manipulate.
In addition, the integrated manipulation apparatus 10 in some forms of the present disclosure is a portable manipulation apparatus that the user can move to a desired position while holding the apparatus in their hands. The integrated manipulation apparatus is small and light, and therefore it is possible to easily manipulate the integrated manipulation apparatus.
Also, in the integrated manipulation apparatus 10 in some forms of the present disclosure, the steering dial switch 210 and the speed change slide switch 240 are different in manipulation manner from the acceleration button switch 220 and the braking button switch 230. Consequently, it is possible to maximally prevent unintentional manipulation.
As is apparent from the above description, an integrated manipulation apparatus in some forms of the present disclosure has an effect in that, when a driving mode is switched from an autonomous driving mode to a manual driving mode, a user manipulates the integrated manipulation apparatus in the state of carrying the integrated manipulation apparatus to perform chassis functions, such as steering, speed change, acceleration, and braking of a vehicle, and to perform general functions, such as lamp on/off, honking, and turn indication, as needed, whereby the integrated manipulation apparatus is easy and convenient to manipulate.
