Abstract
Description
Technical Field
[0001] This invention relates to a control method for switching to manual driving mode in an autonomous vehicle equipped with a foldable pedal device. More specifically, this invention relates to a control method that allows switching from autonomous driving mode to manual driving mode only when both safety conditions and the shim's pop-out position condition are simultaneously met. Background Technology
[0002] Autonomous vehicles are intelligent vehicles that incorporate autonomous driving technology. In autonomous driving technology, the vehicle can reach its destination automatically even without the driver directly operating the steering wheel, accelerator pedal, brakes, etc. Recently, autonomous vehicles have experienced rapid development.
[0003] When autonomous driving is widely implemented, drivers can choose between a manual driving mode where the driver is directly in control and an autonomous driving mode where the vehicle automatically drives to the destination without the driver being directly in control.
[0004] In autonomous driving mode, the driver can stretch their legs and rest comfortably. Therefore, if the pedals (accelerator and brake pedals) located in the space under the driver's seat are still exposed in the vehicle interior, it will hinder the driver's rest. In particular, regardless of the driver's intention, misoperation of the pedal mechanism pads will forcibly terminate autonomous driving, thus posing a high risk of an accident.
[0005] Therefore, a foldable pedal device is being actively developed for autonomous vehicles. This foldable pedal device ensures that in manual driving mode, where the driver is directly in control, the pedal pad is prominently exposed to the driver so that the driver can operate it. In autonomous driving mode, the pedal pad is concealed so that it is not protruding to the driver, thus preventing the driver from operating it. This facilitates driver comfort and safety, such as preventing accidental operation.
[0006] In existing technology, when an autonomous vehicle equipped with such a foldable pedal device is driving in autonomous driving mode, and a signal is generated to switch the driving mode to manual driving mode via the controller, there is no process to check safety conditions to determine whether the switching to manual driving mode is feasible. Therefore, the pedal device pad may be operated and protrude towards the driver based on the manual driving mode signal, and if the pedal device pad is mistakenly operated by the driver, there is a risk of an accident.
[0007] The information included in this background section is intended only to enhance the understanding of the general background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0008] Various aspects of the present invention aim to provide a control method for switching driving modes, wherein when a signal for switching the driving mode from automatic driving mode to manual driving mode is generated in an autonomous vehicle equipped with a foldable accelerator pedal device and a foldable brake pedal device, a safety condition is checked to determine whether the driving mode can be switched to manual driving mode; when the safety condition is met, it is determined whether the pop-out positions of the accelerator pedal device shim and the brake pedal device shim are both in normal pop-out positions; and the driving mode is switched to manual driving mode only when the positions of the accelerator pedal device shim and the brake pedal device shim are both in normal pop-out positions. Therefore, accidents caused by incorrect operation are prevented and driving safety is improved.
[0009] Various aspects of the present invention aim to provide a control method for switching to manual driving mode in an autonomous vehicle equipped with a foldable pedal device. The method includes: a determination step, in which, when a signal for manual driving mode is generated in autonomous driving mode, the controller uses a detection signal from a safety check sensor to determine whether the driving mode can be switched to manual driving mode; and a shim ejection step, in which, when the controller determines in the determination step that the driving mode can be switched to manual driving mode, a first actuator of the foldable accelerator pedal device and a second actuator of the foldable brake pedal device are operated under the control of the controller, and through the operation of the first and second actuators, the foldable accelerator pedal device... The accelerator pedal and the foldable brake pedal respectively perform an ejection operation, causing the pads of the foldable accelerator pedal and the foldable brake pedal to protrude towards the driver; after the pad ejection step, the first pad position sensor and the second pad position sensor connected to the controller are used to detect the positions of the pads of the foldable accelerator pedal and the foldable brake pedal respectively; and only when the controller determines in the pad position detection step that the positions of the pads of the foldable accelerator pedal and the foldable brake pedal are in the normal ejection position, the controller controls the switching of the driving mode to manual driving mode.
[0010] When the controller determines in the judgment step that the driving mode cannot be switched to manual driving mode, the warning device is operated under the control of the controller. The pads of the foldable accelerator pedal device and the foldable brake pedal device remain hidden and do not protrude in the predetermined direction, and the vehicle continues to maintain the automatic driving mode.
[0011] If, during the pad position detection step, it is determined that either the pad position of the foldable accelerator pedal device or the pad position of the foldable brake pedal device is not in a normal pop-out position, the warning device is activated under the control of the controller. The pads of the foldable accelerator pedal device and the foldable brake pedal device return to a hidden state where they are concealed and do not protrude in the predetermined direction, and the vehicle continues to maintain the autonomous driving mode.
[0012] After the shim position detection step, when the vehicle switches the driving mode from automatic driving mode to manual driving mode, the vehicle's steering wheel performs a pop-out operation towards the driver under the control of the controller.
[0013] When the pads of the foldable accelerator pedal and the foldable brake pedal remain hidden, the vehicle's steering wheel also remains hidden and does not protrude in the predetermined direction under the control of the controller.
[0014] The detection signal from the safety check sensor can be a signal that uses the driver detection sensor to detect whether the driver is in the vehicle, and the controller determines that the driving mode can be switched to manual driving mode only when the first condition of the driver being in the vehicle is met.
[0015] The detection signal from the safety inspection sensor can be a signal that detects the second condition of the driver's seat position using the seat position sensor, and the controller determines that the driving mode can be switched to manual driving mode only when the first condition and the second condition that the driver's seat position is a position that allows manual driving of the vehicle are met.
[0016] The detection signal of the safety inspection sensor can be a signal of the third condition for detecting the current state of the driver using the driver state detection sensor. The controller determines that the driving mode can be switched to manual driving mode only when the first condition, the second condition, and the third condition that the current state of the driver is capable of manually driving the vehicle are met.
[0017] The driver detection sensor can be a weight sensor or an ultrasonic sensor, and the driver status detection sensor can be a sensor that uses camera information.
[0018] Warnings generated by a warning device may include at least one of visual warnings, auditory warnings, and tactile warnings.
[0019] According to an exemplary embodiment of the present invention, when a signal for switching the driving mode from automatic driving mode to manual driving mode is generated in an autonomous vehicle equipped with a foldable accelerator pedal device and a foldable brake pedal device, a safety check sensor first checks the safety conditions to determine whether the driving mode can be switched to manual driving mode. If the safety conditions are met, it is determined whether the pop-out positions of the shims of the foldable accelerator pedal device and the foldable brake pedal device are both in their normal pop-out positions. The driving mode is switched to manual driving mode only when the positions of the shims of the foldable accelerator pedal device and the foldable brake pedal device are both in their normal pop-out positions, and simultaneously, the steering wheel is popped out to allow the driver to operate it. Therefore, accidents caused by incorrect operation are prevented and driving safety is significantly improved.

In this document, the memory and processor may be implemented as separate chips. Alternatively, the memory and processor may be implemented as an integrated single chip. The processor may be configured as one or more processors.
[0033] In the following description, with reference to the accompanying drawings, a control method for switching to manual driving mode in an autonomous vehicle equipped with a foldable pedal device according to various exemplary embodiments of the present invention will be described.
[0034] Autonomous vehicles can choose between a manual driving mode where the driver is directly in control and an autonomous driving mode where the vehicle travels to the destination without the driver's direct control.
[0035] In addition, autonomous vehicles can be equipped with foldable pedals. For example... Figure 1 As shown, the foldable pedal device includes a foldable accelerator pedal device 10 and a foldable brake pedal device 20.
[0036] The foldable accelerator pedal device 10 and the foldable brake pedal device 20 respectively include housings 11 and 21 and gaskets 12 and 22 rotatably connected relative to housings 11 and 21.
[0037] Housings 11 and 21 can be installed in the space below the driver's seat inside the vehicle interior. Pads 12 and 22 are operated by the driver's feet.
[0038] In an autonomous vehicle equipped with a foldable accelerator pedal device 10 and a foldable brake pedal device 20, in manual driving mode, the driver directly operates the pads 12 and 22 with their feet. For this purpose, the pads 12 and 22 need to be in a popped-out state, protruding from their respective housings 11 and 21 to be exposed to the driver.
[0039] Furthermore, in autonomous driving mode, for the driver's comfort and safety, such as preventing accidental operation, the gaskets 12 and 22 need to be hidden by inserting the gaskets 12 and 22 into their respective housings 11 and 21, so that the gaskets 12 and 22 do not protrude to the driver.
[0040] To achieve the pop-up and retracted states of the pads 12 and 22 as described above, the foldable accelerator pedal device 10 and the foldable brake pedal device 20 further include a first actuator 13 and a second actuator 23, respectively, which forcibly rotate their respective pads 12 and 22. The first actuator 13 and the second actuator 23 may each include a motor, and the operation of the first actuator 13 and the second actuator 23 is controlled by the controller 30.
[0041] According to various exemplary embodiments of the present invention, when a signal for manual driving mode is generated during autonomous driving in an autonomous vehicle equipped with a foldable accelerator pedal device 10 and a foldable brake pedal device 20, a safety condition is first used to determine whether the driving mode can be switched to manual driving mode. When the safety condition is met, it is determined whether the pop-out position of the pad 12 of the foldable accelerator pedal device 10 and the pop-out position of the pad 22 of the foldable brake pedal device 20 are both in normal pop-out positions. The driving mode is switched to manual driving mode only when the positions of the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 are both in normal pop-out positions, and the steering wheel 70 is popped out to allow the driver to operate it.
[0042] In other words, such as Figure 1 , Figure 2 and Figure 3As shown, the control method according to various exemplary embodiments of the present invention includes: a determination step, in which, when a signal for a manual driving mode is generated in an automatic driving mode, the controller 30 uses the detection signal of the safety check sensor 40 to determine whether the driving mode can be switched to a manual driving mode; and a shim ejection step, in which, when the controller determines in the determination step that the driving mode can be switched to a manual driving mode, the first actuator 13 of the foldable accelerator pedal device 10 and the second actuator 23 of the foldable brake pedal device 20 operate respectively under the control of the controller 30, and the ejection operation is performed by the operation of the first actuator 13 and the second actuator 23 respectively, thereby enabling the shim to be ejected. The pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 protrude toward the driver; in the pad position detection step, after the pad ejection step, the positions of the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 are detected by the first pad position sensor 14 and the second pad position sensor 24, respectively; and the controller only controls the switching of the driving mode to manual driving mode when the controller 30 determines in the pad position detection step that the positions of the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 are in the normal ejection position.
[0043] For example, the driving mode of an autonomous vehicle can be switched by operating a driving mode switch 50. The driving mode switch 50 may include an autonomous driving mode switch 51 and a manual driving mode switch 52.
[0044] When the controller determines during the judgment step that the driving mode cannot be switched to manual driving mode, the warning device 60 is activated under the control of the controller 30, and the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 remain hidden and do not protrude to the driver. At this time, the vehicle continues to maintain the automatic driving mode.
[0045] If, during the pad position detection step, it is determined that either the position of the pad 12 of the foldable accelerator pedal device 10 or the position of the pad 22 of the foldable brake pedal device 20 is not in the normal pop-out position, the warning device 60 is operated under the control of the controller 30. Through the operation of the first actuator 13 and the second actuator 23 under the control of the controller 30, the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 return to the hidden state where they are concealed and do not protrude to the driver, and the vehicle continues to maintain the automatic driving mode.
[0046] Warning lights, warning sound generators, displays, etc., can be used as warning devices 60. The warnings generated by the warning device 60 preferably include at least one of visual warnings, auditory warnings, and tactile warnings.
[0047] When the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 perform a pop-out operation towards the driver, the steering wheel 70 of the vehicle also performs a pop-out operation towards the driver under the control of the controller 30, so that the driver can drive manually.
[0048] Conversely, when the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 remain hidden, the vehicle's steering wheel 70 also remains hidden and does not protrude towards the driver under the control of the controller 30, for automatic driving.
[0049] The detection signal from the safety check sensor 40 is a signal from the driver detection sensor 41 used to detect whether the driver is in the vehicle, fulfilling a first condition. Only when the first condition of the driver being in the vehicle is met does the controller 30 determine that the driving mode can be switched to manual driving mode.
[0050] The driver detection sensor 41 can use a weight sensor to identify whether a passenger is in the vehicle based on weight, or an ultrasonic sensor to identify whether a passenger is in the vehicle based on ultrasound.
[0051] Furthermore, the detection signal from the safety check sensor 40 is a signal from the seat position sensor 42 that detects a second condition regarding the driver's seat position. The controller 30 determines that the driving mode can be switched to manual driving mode only when the first condition and the second condition—that the driver's seat position is such that the vehicle can be manually driven—are met.
[0052] Furthermore, the detection signal from the safety check sensor 40 is a signal that detects the third condition of the driver's current state using the driver state detection sensor 43. The controller 30 determines that the driving mode can be switched to manual driving mode only when the first condition, the second condition, and the third condition that the driver's state is capable of manually driving the vehicle are met.
[0053] The driver state detection sensor 43 is a sensor that uses camera information and is a system that uses infrared (IR) light-emitting diodes (LEDs) and cameras to obtain images of the driver's facial orientation and eye opening and closing, and determines negligent driving based on the obtained images, and then combines with the chassis safety system to provide early warning before an accident occurs, thereby achieving a pre-safety function.
[0054] The chassis safety system may include at least one of the following: intelligent cruise control system, highway driving assistance system, forward collision avoidance assist system, blind spot collision avoidance assist system, and rear cross traffic collision avoidance assist system.
[0055] The first shim position sensor 14 and the second shim position sensor 24 are sensors that detect the positions of the shim 12 of the foldable accelerator pedal device 10 and the shim 22 of the foldable brake pedal device 20, respectively. The positions of the shims 12 and 22 can be detected by the rotation angle of the shims 12 and 22. Hall effect sensors can be used for this purpose.
[0056] For example, in the case of an autonomous vehicle equipped with a foldable pedal device, the autonomous driving mode is recognized as the default driving mode when the door is opened and the engine is started.
[0057] In autonomous driving mode, in step S1, a signal for manual driving mode is generated by manipulating the manual driving mode switch 52. In step S2, the controller 30 uses the detection signal from the driver detection sensor 41 to determine whether the driver is in the vehicle.
[0058] When it is determined that the driver is not in the vehicle, in step S3, for safety reasons, the warning device 60 is activated. In step S4, the pad 12 of the foldable accelerator pedal device 10, the pad 22 of the foldable brake pedal device 20, and the steering wheel 70 remain hidden. In step S5, the vehicle continues to operate in automatic driving mode.
[0059] When it is determined that the driver is in the vehicle, in step S6, the detection signal of the seat position sensor 42 is used to determine whether the position of the driver's seat is a position that allows for manual driving.
[0060] When it is determined that the driver's seat is in a position where manual driving is not possible, in step S3, for safety reasons, the warning device 60 is activated. In step S4, the pad 12 of the foldable accelerator pedal device 10, the pad 22 of the foldable brake pedal device 20, and the steering wheel 70 remain hidden. In step S5, the vehicle continues to operate in automatic driving mode.
[0061] When it is determined that the driver's seat is in a position where manual driving is possible, in step S7, the detection signal of the driver state detection sensor 43 is used to determine whether the driver's current state is a state where manual driving is possible.
[0062] When it is determined that the driver's current state is incapable of manual driving, in step S3, for safety reasons, the warning device 60 is activated. In step S4, the pad 12 of the foldable accelerator pedal device 10, the pad 22 of the foldable brake pedal device 20, and the steering wheel 70 remain hidden. In step S5, the vehicle continues to operate in automatic driving mode.
[0063] When it is determined that the driver's current state is capable of manual driving, in steps S8 and S9, the first actuator 13 and the second actuator 23 operate under the control of the controller 30.
[0064] By operating the first actuator 13, the state of the pad 12 of the foldable accelerator pedal device 10 changes from a hidden state to a pop-out state. By operating the second actuator 23, the state of the pad 22 of the foldable brake pedal device 20 changes from a hidden state to a pop-out state.
[0065] When the first actuator 13 is operated, the first shim position sensor 14 detects the rotation angle of the shim 12 of the foldable accelerator pedal device 10 to detect the position of the shim 12 of the foldable accelerator pedal device 10. Furthermore, when the second actuator 23 is operated, the second shim position sensor 24 detects the rotation angle of the shim 22 of the foldable brake pedal device 20 to detect the position of the shim 22 of the foldable brake pedal device 20.
[0066] After the first actuator 13 is operated, in step S10, the controller 30 uses the detection signal of the first pad position sensor 14 to determine whether the position of the pad 12 of the foldable accelerator pedal device 10 is the normal pop-out position.
[0067] Furthermore, after the second actuator 23 is operated, in step S11, the controller 30 uses the detection signal of the second pad position sensor 24 to determine whether the position of the pad 22 of the foldable brake pedal device 20 is the normal pop-out position.
[0068] As a result of the judgments in steps S10 and S11, the steering wheel 70 is switched from the hidden state to the pop-up state in step S12 only when the position of the pad 12 of the foldable accelerator pedal device 10 and the position of the pad 22 of the foldable brake pedal device 20 are determined to be in the normal pop-up position, and in step S13, the vehicle is controlled to switch the driving mode from the automatic driving mode to the manual driving mode.
[0069] However, as a result of the judgments in steps S10 and S11, if it is determined that either the position of the pad 12 of the foldable accelerator pedal device 10 or the position of the pad 22 of the foldable brake pedal device 20 is not in the normal pop-out position, in step S3, for safety reasons, the warning device 60 is activated. In step S4, through the operation of the first actuator 13 and the second actuator 23 under the control of the controller 30, the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 return to a hidden state where they are concealed and do not protrude towards the driver, and the steering wheel 70 remains hidden. In step S5, the vehicle continues to maintain the automatic driving mode.
[0070] As described above, according to an exemplary embodiment of the present invention, when a signal for switching the driving mode from automatic driving mode to manual driving mode is generated in an autonomous vehicle equipped with a foldable accelerator pedal device 10 and a foldable brake pedal device 20, the safety check sensor 40 first checks the safety conditions to determine whether the driving mode can be switched to manual driving mode. When the safety conditions are met, it is determined whether the pop-out positions of the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 are both in normal pop-out positions. The driving mode is switched to manual driving mode only when the positions of the pad 12 of the foldable accelerator pedal device 10 and the pad 22 of the foldable brake pedal device 20 are both in normal pop-out positions, and the steering wheel 70 is popped out to allow the driver to operate it. Therefore, accidents caused by incorrect operation can be prevented and driving safety can be greatly improved.
[0071] Furthermore, the term "controller" refers to a hardware device including a memory and a processor, the processor being configured to execute one or more steps described as an algorithmic structure.

[0072] The controller may be at least one microprocessor operated by a predetermined program, which may include a series of commands for implementing methods according to various exemplary embodiments of the present invention.
[0073] The invention described above can also be implemented as computer-readable code on a computer-readable recording medium.
