This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2019-135359 filed on Jul. 23, 2019, the disclosure of which is incorporated by reference herein.
The present disclosure relates to an operating portion control device and a vehicle control system.
Japanese Patent Application Laid-Open (JP-A) No. 2018-184122 discloses an invention relating to an auxiliary brake device for a training vehicle. In this auxiliary brake device for a training vehicle, a brake pedal (an operating portion) disposed at a front passenger seat side and a brake device disposed at a driver seat side are connected via a cable. When the brake pedal at the front passenger seat side is pressed, the brake device operates.
In a training vehicle, with a view to improving technique of an occupant of a driver seat, which is to say a training student (a first operator), it is preferable if operation amounts of a steering wheel and operation amounts of a brake pedal can be demonstrated directly to the training student by a trainer (a second operator). Further, with a view to the trainer checking a proficiency level of the training student, it is preferable if the trainer can verify operation amounts of the steering wheel and operation amounts of the brake pedal by the training student.
In the conventional technology recited in JP-A No. 2018-184122, although the brake device may be operated from the front passenger seat side, operation amounts of the brake pedal by an occupant at the front passenger seat side may not be transmitted to an occupant at the driver seat side. In other words, there is scope for improvement of the technology recited in JP-A No. 2018-184122 in regard to transmitting operation amounts of operating portions between a first operator and a second operator.
An aspect of the disclosure is an operating portion control device that includes: a memory and a processor connected to the memory. The processor is configured to: acquire operation amount information of a first operating portion that operates a vehicle; send first signals representing the operation amount information of the first operating portion, and receive second signals representing operation amount information of a second operating portion that operates the vehicle, the second operating portion being different from the first operating portion; switch between a state of sending the first signals and a state of receiving the second signals; and, on the basis of the second signals received in the state of receiving, actuate the first operating portion in accordance with an operation amount of the second operating portion.

Now, using
The operation information acquisition section 180 acquires data detected by the operation sensors 42 of the operation section 34 and sends this data to the communications section 181 and the control section 183. The operation information acquisition section 180 also acquires data such as captured images and the like acquired by the external sensors 28 and sends this data to the communications section 181. The operation information acquisition section 180 further acquires operation information from signals S1, which serve as first signals and are described below. That is, the operation information acquisition section 180 acquires operation amounts (first operation amount information) of others of the operating devices 40 that are at an operation section 50 of the remote operation equipment 14, which serves as a first operation section and is described below. The operation information acquisition section 180 sends signals based on these operation amounts to the control section 183.
The communications section 181 receives the signals S1 sent from the remote operation equipment 14. The communications section 181 sends the signals received from the operation information acquisition section 180, that is, signals S2 representing operation amounts of the operating devices 40 at the operation section 34 that serve as second signals (second operation amount information), to the server 16. The communications section 181 also sends data acquired by the external sensors 28 to the server 16.
The autonomous driving information acquisition section 182 acquires autonomous driving information, that is, data required for autonomous driving of the vehicle 12. The information acquired by the autonomous driving information acquisition section 182 includes position information of the vehicle 12 determined by the GPS device 26, data relating to the environment surrounding the vehicle 12 that is acquired by the external sensors 28, data relating to running states of the vehicle 12 that is acquired by the internal sensors 30, and environment information obtained from the server 16. The above-described data acquired by the autonomous driving information acquisition section 182 is sent to the control section 183.
As is described below, the control section 183 drives the actuation section 32, controlling running of the vehicle 12, on the basis of the signals S1 that the communications section 181 receives from the remote operation equipment 14. That is, in the present exemplary embodiment the control section 183 functions as a remote operation control section.
A destination is entered at a touch panel 48 connected to a driving switching section 203 of the remote operation equipment 14, which is described below. The control section 183 controls the actuation section 32 and conducts autonomous driving of the vehicle 12 on the basis of the destination and information acquired by the autonomous driving information acquisition section 182. That is, in the present exemplary embodiment the control section 183 also functions as an autonomous driving control section.
As described in detail below, the control section 183 drives the operation section 34 on the basis of signals sent from the operation information acquisition section 180 that are based on the signals S1 from the remote operation equipment 14. That is, in the present exemplary embodiment the control section 183 also functions as a second actuation control section.
Now, using
More specifically, as shown in
The communications section 161 receives the signals S1 sent from the remote operation equipment 14 and the signals S2 sent from the vehicle 12. On the basis of the data acquired by the server control section 160, the communications section 161 sends the signals S1 and signals based on the various kinds of data to the vehicle 12, and sends the signals S2 and signals based on the various kinds of data to the remote operation equipment 14.
Now, structures of the remote operation equipment 14 are described. As shown in
Hardware structures of the remote control device 20 have basically similar structures to the vehicle control device 18. The remote control device 20 functions as an assembly of an operation information acquisition section 200 that serves as a first operation information acquisition section, a communications section 201 that serves as a first communications section, a control section 202, and the driving switching section 203. The display section 46, the touch panel 48 and the operation section 50 are connected to the remote control device 20 to be capable of mutual communications with the remote control device 20.
The operation information acquisition section 200 acquires data detected by the operation sensors 42 of the operation section 50, and sends the data to the communications section 161 and the control section 202. The operation information acquisition section 200 also sends to the control section 202 data based on signals sent from the vehicle 12 via the communications section 201. Specifically, the operation information acquisition section 200 acquires operation information from the signals S2, that is, operation amounts of the operating devices 40 of the operation section 34 at the vehicle 12, and sends signals based on these operation amounts to the control section 202.
On the basis of signals received from the operation information acquisition section 200, the communications section 201 sends the signals 51 representing operation amounts of the operating devices 40 at the operation section 50 to the server 16. In addition, the communications section 201 receives the signals S2 and signals based on various kinds of data from the server 16. The data sent from the server 16 includes data acquired by the external sensors 28 of the vehicle 12, including images captured by the camera 28A, environmental information and so forth.
The control section 202 drives the operation section 50 on the basis of the signals S2 from the vehicle 12. That is, in the present exemplary embodiment the control section 202 functions as a first actuation control section. On the basis of data acquired from the operation information acquisition section 200, the control section 202 displays images captured by the camera 28A of the vehicle 12 on plural displays constituting the display section 46.
On the basis of the signals from the touch panel 48, the driving switching section 203 sends status signals to the vehicle control device 18 via the control section 202 and communications section 201. In more detail, the touch panel 48 is provided with a liquid crystal display, and a selection screen is displayed at the liquid crystal display. The selection screen is for selection of an autonomous driving mode, a remote driving mode, a manual driving mode, a first training mode that serves as a first mode, or a second training mode that serves as a second mode.
When the driver 22 operates the touch panel 48 and selects a mode from the plural modes mentioned above, status signals indicating that the vehicle control system 10 is in that mode are sent from the driving switching section 203 to the control section 202 and the vehicle control device 18, and the vehicle control system 10 switches into that mode. The vehicle control device 18 and the remote control device 20 are configured so as to detect the status signals at predetermined time intervals.
More specifically, when the autonomous driving mode is selected by the driver 22, the vehicle control device 18 of the vehicle 12 controls the actuation section 32 with the control section 183 on the basis of the data acquired by the autonomous driving information acquisition section 182, and the vehicle control device 18 conducts autonomous driving of the vehicle 12. When the autonomous driving mode is selected at the touch panel 48, a map of the vicinity of the vehicle 12 may be displayed at the liquid crystal display of the touch panel 48 and the driver 22 may designate a destination for the vehicle 12. In the autonomous driving mode, the vehicle control device 18 of the vehicle 12 controls the actuation section 32 such that the actuated devices 38 are not effective for operation of the operating devices 40 by the driver 24.
Alternatively, when the remote operation mode is selected by the driver 22, the vehicle control device 18 of the vehicle 12 drives the actuation section 32, controlling running of the vehicle 12, on the basis of the signals S1 sent from the remote operation equipment 14. Meanwhile, the driver 22 operates the operating devices 40 at the operation section 50 in accordance with images displayed at the display section 46 and the like. Thus, the driver 22 remotely operates the vehicle 12. In the remote operation mode, the vehicle control device 18 controls the actuation section 32 such that the actuated devices 38 are not effective for operation of the operating devices 40 by the driver 24.
When the manual driving mode is selected by the driver 22, the actuated devices 38 of the vehicle 12 operate in accordance with operations of the operation section 34 by the driver 24. In the manual operation mode, the vehicle control device 18 stops sending signals to the actuation section 32.
Now, the first training mode and the second training mode are described. These modes are modes in which the vehicle 12 is employed as a training vehicle. When the vehicle control system 10 is in these modes, the driver 22 is a trainer and the driver 24 is a training student.
In the first training mode, similarly to the remote operation mode, the driver 22 operates the operating devices 40 at the operation section 50 in accordance with images displayed at the display section 46 and the like, remotely operating the vehicle 12.
In this first training mode, at the operation section 50 of the remote operation equipment 14, operation amounts of the operating devices 40 by the driver 22 are detected by the operation sensors 42. These operation amounts are sent from the remote operation equipment 14 to the vehicle 12 in the form of the signals S1.
Meanwhile, at the vehicle 12 side, the signals S1 are received by the vehicle control device 18 and the operation actuators 44 at the operation section 34 are actuated on the basis of the signals S1, thus actuating the operating devices 40. That is, in the first training mode, operation amounts of the operating devices 40 by the driver 22 are reflected at the operating devices 40 at the vehicle 12 side.
In the second training mode, similarly to the manual driving mode, the driver 24 operates the operating devices 40 at the operation section 34, operating the vehicle 12.
In this second training mode, at the operation section 34 of the vehicle 12, operation amounts of the operating devices 40 by the driver 24 are detected by the operation sensors 42. These operation amounts are sent from the vehicle 12 to the remote operation equipment 14 in the form of the signals S2.
Meanwhile, at the remote operation equipment 14 side, the signals S2 are received by the remote control device 20 and the operation actuators 44 at the operation section 50 are actuated on the basis of the signals S2, thus actuating the operating devices 40. That is, in the second training mode, operation amounts of the operating devices 40 by the driver 24 are reflected at the operating devices 40 at the remote operation equipment 14 side.
When the driving switching section 203 switches between the first training mode and the second training mode, the state of sending and the state of receiving the signals S1 and signals S2 are switched at the communications section 181 of the vehicle control device 18 and the communications section 201 of the remote control device 20. Therefore, the driving switching section 203 may be regarded as switching the state of sending signals and the state of receiving signals between the communications section 181 and the communications section 201.
Now, operation and effects of the present exemplary embodiment are described.
In the vehicle control system 10 according to the present exemplary embodiment, as described above, the autonomous driving mode, the remote driving mode, the manual driving mode, the first training mode and the second training mode may be selected. Below, principally using the flowcharts shown in

In step S205, on the basis of the status signals from the remote operation equipment 14, the CPU 18A detects the driving mode of the vehicle 12 and makes a determination as to whether the first training mode has ended. If the first training mode is continuing (“No” in step S205), the CPU 18A returns to step S202. If the first training mode is ending, (“Yes” in step S205), the CPU 18A ends this control flow.
Alternatively, when the CPU 18A has proceeded from step S201 to step S203, the CPU 18A makes a determination on the basis of the detection results from step S200 as to whether the driving mode of the vehicle 12 is the second training mode.
