Steering wheel controls have emerged as a desirable location to place features in an effort to offer quick and easy access to features believed to be important to the driver and to help them remain focused on the road, e.g., eyes on the road, hands on the wheel. The migration of features to the steering wheel has added considerable complexity to the steering wheel and the use of its controls.
It is therefore be desirable to provide physicality at the steering wheel, as well as steering wheel interactions that are quick, tactile, and blind like in operation of the most frequently used controls, e.g., functions that are most needed while driving, such that drivers need not navigate deep menu structures from the steering wheel.
It is with respect to these and other considerations that the disclosure made herein is presented.
The detailed description is set forth with reference to the accompanying drawings. The use of the same reference numerals may indicate similar or identical items. Various embodiments may utilize elements and/or components other than those illustrated in the drawings, and some elements and/or components may not be present in various embodiments. Elements and/or components in the figures are not necessarily drawn to scale. Throughout this disclosure, depending on the context, singular and plural terminology may be used interchangeably.
Systems and methods are provided herein to simplify the functional offerings of vehicle control settings to those most frequently used by drivers. Functions are classified as primary and secondary to limit the number of functions shown to the user at one time. This allows for a compact and simple switch set, e.g., 10-15 position switch set, improving findability and memorable operation. A virtual image of the switch set is depicted in the large information display showing the appropriate control for the task at hand (contextually appropriate controls). With the function graphics/instruction shown in the display, the graphics may be removed from the switch itself allowing for the user to interact with multipurpose controls that are easily understood and not limited by hard graphics printed on a switch. The use of the display reduces the driver's downward gaze when interacting with steering wheel functions, thereby keeping their eyes up and out closer to the road. Capacitive technology is leveraged to offer proximity sensing (finger trace) capability helping the user identify the function they wish to interact with without glancing down at the switch itself, which is an improvement over having to remove your thumb from the switch to see the labels. Additionally, driver adjustment settings may be added to the steering wheel as it creates a natural postural correct interaction for the driver.
To help create an advanced set of steering wheel controls described herein, a thorough evaluation of the current functionality was completed prior to ideating on concepts. For example, control functionalities found to be used infrequently were consolidated or eliminated based on leveraging surveys and big data analysis. In addition, traditional cluster settings were moved to the center screen to eliminate menu buttons, which opens up space in the display for the digital virtual switch. Moreover, to take advantage of the driver's natural postural position, power mirrors, power steering column, and power pedal controls were moved to the steering wheel, such that the user's hands would remain on the wheel when making these adjustments. This enables the addition of mirrors, tilt-tele, power pedals, etc., which creates a great experience for the driver by offering adjustments at their fingertips in their natural driving positions. Through the use of the virtual switch, the active functional state of these multipurpose buttons is easily communicated to the driver.
In accordance with some aspects of the present disclosure, the systems described herein include large vehicle information displays including, but not limited to, high heads down displays, panoramic displays, HUD, and large clusters. By leveraging the larger displays, a digital virtual image of the switch may be created in the information display. Accordingly, the driver still physically interacts with the switch, but their eyes glance no lower than the informational display, which offers an improved downward viewing angle.
Moreover, the system removes physical label graphics on the actuators of the switch set. With a digital image of the contextually appropriate control set in the information display, there is no longer a need to place graphics on the switches themselves. Accordingly, there is no longer a need to glance down to the switch itself. In addition, the lack of graphics offers the ability to swap left hand and right hand controls.
The systems described herein provide contextual-dependent functionality, e.g., the system offers the right control at the right time. For example, the right hand primary first surface controls may include audio functions, but when a paired phone receives an incoming phone call, those same controls change purpose allowing the user to quickly answer the phone call, which preserves functionality while minimizing buttons. Thus, the functions associated with the controls are contextually dependent on the vehicle control settings accessible by the user. The active control set is easily communicated to the driver virtually using the large information display. Moreover, the amount of first surface buttons may be reduced. Specifically, the contextual ability of the switch enables limitation of the amount of first surface buttons to, e.g., 10-15 buttons, thereby improving findability and memorable operation.
In addition, the system utilizes a capacitive switch set, which supports proximity sensing, e.g., finger trace. For example, the system detects and communicates to the user the location of their thumb on the switch and uses the signal to display the virtual switch image in the HMI, which supports blind like operation. This enhances the experience by allowing the user to keep their hands on the switch while identifying the intended control. Moreover, the switch utilizes a haptic response to tactilely communicate the interaction with the switch to the user even without looking at the display. Accordingly, with the control set being displayed virtually to the driver, the switch is easily adaptable to other purposes and future functionality that could be deployed via OTA updates.
The disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the disclosure are shown. This disclosure may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. It will be apparent to persons skilled in the relevant art that various changes in form and detail can be made to various embodiments without departing from the spirit and scope of the present disclosure.

The vehicle may be a manually driven vehicle (e.g., no autonomy) and/or configured and/or programmed to operate in a fully autonomous (e.g., driverless) mode (e.g., Level-5 autonomy) or in one or more partial autonomy modes which may include driver assist technologies, e.g., adaptive cruise control. Examples of partial autonomy (or driver assist) modes are widely understood in the art as autonomy Levels 1 through 4. A vehicle having a Level-0 autonomous automation may not include autonomous driving features. An autonomous vehicle (AV) having Level-1 autonomy may include a single automated driver assistance feature, such as steering or acceleration assistance. Adaptive cruise control is one such example of a Level-1 autonomous system that includes aspects of both acceleration and steering. Level-2 autonomy in vehicles may provide partial automation of steering and acceleration functionality, where the automated system(s) are supervised by a human driver that performs non-automated operations such as braking and other controls. In some aspects, with Level-2 autonomous features and greater, a primary user may control the vehicle while the user is inside of the vehicle, or in some example embodiments, from a location remote from the vehicle but within a control zone extending up to several meters from the vehicle while it is in remote operation. Level-3 autonomy in a vehicle can provide conditional automation and control of driving features. For example, Level-3 vehicle autonomy typically includes “environmental detection” capabilities, where the vehicle can make informed decisions independently from a present driver, such as accelerating past a slow-moving vehicle, while the present driver remains ready to retake control of the vehicle if the system is unable to execute the task. Level-4 autonomous vehicles can operate independently from a human driver, but may still include human controls for override operation. Level-4 automation may also enable a self-driving mode to intervene responsive to a predefined conditional trigger, such as a road hazard or a system failure. Level-5 autonomy is associated with autonomous vehicle systems that require no human input for operation, and generally do not include human operational driving controls. According to embodiments of the present disclosure, virtual steering wheel controller platform 300 may be configured and/or programmed to operate with a vehicle having a Level-4 or Level-5 autonomous vehicle controller.
Virtual steering wheel controller platform 300 may be stored and executed via a vehicle control module of the vehicle. The vehicle control module may communicate with steering wheel 200, display 150, and the electrical and mechanical components of the vehicle over a network, e.g., any one, or a combination of networks, such as a local area network (LAN), a wide area network (WAN), a telephone network, a cellular network, a cable network, a wireless network, and/or private/public networks, such as the Internet. For example, the network may support communication technologies, such as TCP/IP, Bluetooth, cellular, near-field communication (NFC), Wi-Fi, Wi-Fi direct, machine-to-machine communication, man-to-machine communication, and/or a vehicle-to-everything (V2X) communication.
Display 150 is configured to virtually display information indicative of the switch set of steering wheel 200 and vehicle control settings, as described in further detail below. As shown in

Memory 306, which is one example of a non-transitory computer-readable medium, may be used to store operating system (OS) 316, haptic sensors interface module 308, virtual display generation module 310, display interface module 312, and vehicle interface module 314. The modules are provided in the form of computer-executable instructions that may be executed by processor 302 for performing various operations in accordance with the disclosure.
Memory 306 may include any one memory element or a combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, etc.)) and non-volatile memory elements (e.g., ROM, hard drive, tape, CDROM, etc.). Moreover, memory 306 may incorporate electronic, magnetic, optical, and/or other types of storage media. In the context of this document, a “non-transitory computer-readable medium” can be, for example but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: a portable computer diskette (magnetic), a random-access memory (RAM) (electronic), a read-only memory (ROM) (electronic), an erasable programmable read-only memory (EPROM, EEPROM, or Flash memory) (electronic), and a portable compact disc read-only memory (CD ROM) (optical). The computer-readable medium could even be paper or another suitable medium upon which the program is printed, since the program can be electronically captured, for instance, via optical scanning of the paper or other medium, then compiled, interpreted or otherwise processed in a suitable manner if necessary, and then stored in a computer memory.
Haptic sensors interface module 308 may be executed by processor 302 for receiving the signal(s) generated by the actuators of right hand controls 202 and left hand controls 204 of the switch set of steering wheel 200. For example, haptic sensors interface module 308 may receive a signal indicative of when the driver engages with an actuator, but does not actuate the actuator, as well as a signal indicative of when the driver actuates the actuator.
Virtual display generation module 310 may be executed by processor 302 for generating a virtual display of right hand controls 202 and left hand controls 204, and the current functions associated with each of the actuators of the switch set contextually based on the vehicle control settings accessible. For example, the default functions of actuators 202a, 202b, 202c, and 202d may be up cursor, right cursor, down cursor, and left cursor, respectively, such that upon the driver actuating driver adjustment actuator 202f, the functions of actuators 202a, 202b, 202c, and 202d change to steering wheel adjustment, right mirror adjustment, foot pedal adjustment, and left mirror adjustment, respectively. Accordingly, upon actuation of driver adjustment actuator 202f, virtual display generation module 310 will generate a virtual display of right hand controls 202 and left hand controls 204, with the functions associated with right hand controls 202 being steering wheel adjustment, right mirror adjustment, foot pedal adjustment, and left mirror adjustment. In addition, virtual display generation module 310 may generate a virtual display illustrating an indicator to show the driver where their finger/thumb is relative to the switch set. For example, the indicator may include a circle around the particular actuator.
Display interface module 312 may be executed by processor 302 for causing display 150 to display the virtual display generated by virtual display generation module 310.
Vehicle interface module 314 may be executed by processor 302 for causing electrical and mechanical components of the vehicle to be actuated in accordance with the function actuated via the actuators of right hand controls 202 and left hand controls 204. For example, upon actuation of the mirror adjust function by the driver via the actuators of the switch set, vehicle interface module 314 may cause the mirror(s) of the vehicle to adjust in accordance with the actuation by the driver. Similarly, upon actuation of video playback settings by the driver via the actuators of the switch set, vehicle interface module 314 may cause a video playing on a screen of the vehicle to execute functions, e.g., play, pause, fast-forward, etc., in accordance with the actuation by the driver.

The method may proceed from step 1001 directly to step 1006 upon engagement of the actuators of the switch set by the user. Next, at step 1007, the system determines whether the user's engagement with the actuator is a light touch. If the user's engagement with the actuator is a light touch, the method proceeds to step 1008 where display 150 virtually displays the switch set on the HMI screen. At step 1009, the system tracks the movement of the user's thumb/finger, e.g., via the haptic sensors integrated with the actuators of the switch set. At step 1010, display 150 virtually displays an indicator showing the position of the user's thumb/finger relative to the switch set. For example, the indicator may be a circle, a color change, and/or enlarged font, to convey to the user the position of their thumb/finger relative to the switch set.
At step 1011, the system determines whether the user actuated an actuator, e.g., by pressing down on the actuator. If the user did not actuate the actuator, the method returns to step 1009. If the user actuated the actuator, the method proceeds to step 1012 where the vehicle executes the function associated with the actuated actuator. At step 1013, display 150 may display, e.g., a color change and/or a font decrease to inform the user that the function has been selected. At step 1014, the system determines whether a new switch layout, e.g., virtually displayed functions associated with the actuators of the switch set, is required based on the selected function at step 1012. At step 1015, if a new switch layout is not required, the system determines whether the user's thumb/finger remains on the actuator. If the user's thumb/finger does not remain on the switch set, at step 1017, display 150 times out due to inactivity, and the method returns to step 1001 where display 150 displays a blank screen. If the user's thumb/finger does remain on the switch set, the method proceeds to step 1007, where the system determines whether the user's engagement with the actuator is a light touch. If at step 1014, a new switch layout is required, the method proceeds to step 1016, where display 150 virtually displays the new layout, e.g., new set of functions associated with each actuator of the switch set. Next the method proceeds to step 1015 to determine whether the user's thumb/finger remains on the switch set.
If at step 1007, the user's engagement with the actuator is not a light touch, the method proceeds to step 1018, where the system determines whether the user's engagement with the actuator is a heavy touch, e.g., whether the user actuated the actuator. If the user's engagement with the actuator is not a heavy touch, the method returns to step 1001 where display 150 displays a blank screen. If the user's engagement with the actuator is a heavy touch, the method proceeds to step 1019, where display 150 virtually displays the switch set on the HMI screen. At step 1020, display 150 may display, e.g., a color change and/or a font decrease to inform the user that the function has been selected. At step 1021, the vehicle executes the function associated with the actuated actuator.
At step 1022, the system determines whether a new switch layout, e.g., virtually displayed functions associated with the actuators of the switch set, is required based on the selected function at step 1021. At step 1024, if a new switch layout is not required, the system determines whether the user's thumb/finger remains on the actuator. If the user's thumb/finger does not remain on the switch set, at step 1025, display 150 times out due to inactivity, and the method returns to step 1001 where display 150 displays a blank screen. If the user's thumb/finger does remain on the switch set, the method proceeds to step 1009, where the system determines whether the user's engagement with the actuator is a light touch. If at step 1022, a new switch layout is required, the method proceeds to step 1023, where display 150 virtually displays the new layout, e.g., new set of functions associated with each actuator of the switch set. Next the method proceeds to step 1024 to determine whether the user's thumb/finger remains on the switch set.
