Indeed, the terms "first," "second," and the like are fully interchangeable.
FIG. 1 is a flow diagram illustrating an embodiment of a vehicle item selection method. The vehicle-mounted item selection method is applied to a vehicle-mounted system, and the vehicle-mounted system comprises the following steps: the device comprises a rocker or dial controller arranged on a vehicle steering wheel, a processor and a vehicle-mounted screen. As shown in fig. 1, the in-vehicle item selection method 10 includes: the following steps S11 to S15. The respective steps of fig. 1 will be described in detail below.
In step S11, a plurality of items are presented on the in-vehicle screen according to a preset order, wherein the items include a focus item.
In the present embodiment, a plurality of items are arranged according to a preset order and displayed in the in-vehicle screen. In an implementation scenario, as shown in fig. 2, a plurality of items are displayed in a vertical column on the vehicle-mounted screen for the driver to browse, and the icons of the items may include: text boxes, circles, or irregular shapes, are not limiting in this disclosure. The focus item is any one of all items.
In step S12, the jog dial or dial controller is rotated, and a switching command for switching the focus item is transmitted to the processor based on a change in position of the jog dial or dial controller.
In this embodiment, a steering wheel is provided with a rocker or a dial controller, and sends a command for switching a focus item to a processor in the vehicle-mounted system by controlling rotation of the rocker or the dial controller, and further controls the vehicle-mounted screen to execute switching of the focus item according to position change of the rocker or the dial controller. The focus item is switched by controlling the rocker or the dial controller, the operation mode is simple, the distraction of the user is reduced, and the safe driving is convenient to improve.
In one embodiment, a polar coordinate center point is preset at the center of the control area of the rocker or the dial controller, and a switching instruction is sent to the processor according to the position relation between the position change of the rotating rocker or the dial controller and the polar coordinate center point. The central position of the control area where the rocker or the dial controller is located is a control central point, the control center is set to be a polar coordinate central point, the position relation between the position change of the rocker or the dial controller in the control area and the polar coordinate central point is conveniently and quickly acquired, and then the switching of the vehicle-mounted screen system to the focus item is controlled.
In another embodiment, a first angle, a second angle and an angle difference between the second angle and the first angle of the rotary rocker or dial controller are obtained according to the polar coordinate center point. When the rocker or the dial controller detects that the absolute value of the angle difference is equal to or larger than a preset angle threshold, a switching instruction for switching the next or previous item of the current focus item into a new focus item is sent according to the positive or negative angle difference, and the second angle is updated into a new first angle; and when the absolute value of the angle difference is smaller than the preset angle threshold, not sending a switching instruction.
When the rocker or dial controller is not in use, the rocker or dial controller does not contain a rotation angle or the rotation angle is zero. As shown in fig. 3, when the joystick or dial controller starts to rotate, a first angle a, which is a reference angle at which the user moves the joystick or dial controller to a certain direction to start rotating, can be obtained according to the polar coordinate center and the position at which the joystick or dial controller is initially pointed. And according to the position of the polar coordinate center and the real-time movement of the rocker or the dial controller, obtaining a second angle B, namely the real-time angle of the user for rotating the rocker or the dial controller. And presetting a preset angle threshold value of the switching focus item, and when the absolute value of the angle difference theta between the second angle B and the first angle A is larger than the preset angle threshold value, sending a switching instruction for switching the next item or the previous item of the switching focus item to the processor according to the positive value and the negative value of the obtained angle difference theta. When the absolute value of the angle difference theta between the second angle B and the first angle A is smaller than a preset angle threshold value, an instruction for switching the focus item is not sent to the processor. For example: the switching item rule is as follows: when the angle difference is a positive value, sending a switching instruction for switching the next item of the focus item to be a new focus item; and when the angle difference is a negative value, sending a switching instruction for switching the previous item of the focus item to be a new focus item. When the rocker or the dial controller continuously rotates, after the current focus item is switched, the angle at which the second angle B is located is updated to be the new first angle A, the angle difference is obtained again, the comparison with the preset angle threshold value is carried out, and whether a switching instruction for switching the focus item is sent or not is judged. According to the continuous rotation of the user, the switching instruction of the focus item can be continuously sent for multiple times. The focus item is switched according to the angle difference obtained in real time by taking the first angle for starting rotation as a reference, so that the items in the vehicle-mounted screen can be browsed and selected quickly, and the driving safety is not influenced during switching.
In another embodiment, the control area is divided according to the center point of the polar coordinate circle, and the control area is divided into two or more sub-switching areas; and when the rotation angle of the rocker or the dial controller crosses the separation limit between the sub-switching areas, sending a switching instruction for switching the next item or the previous item of the current focus item into a new focus item according to the rotation direction.
And dividing the control area into two or more sub-switching areas according to a preset angle. When the rotation angle of the rocker or the dial controller crosses the separation limit between two adjacent sub-switching areas, a switching instruction for switching the focus item is triggered, and the vehicle-mounted screen switches the focus item according to the rotation direction of the rocker or the dial controller. For example: as shown in fig. 4, the control area is divided into eight sub-switching areas according to a preset 45 ° angle, and the edges of each sub-switching area are marked with scale lines. When the rocker or dial controller crosses a scale through clockwise rotation, a switching instruction for switching the next item of the current focus item into a new focus item is sent; and when the rocker or dial controller rotates anticlockwise and crosses a scale, sending a switching instruction for switching the previous item of the current focus item into a new focus item. According to the continuous rotation of the user, the switching instruction for switching the focus item can be continuously triggered for multiple times. By controlling the switching focus items in different areas, the control area on the steering wheel can process data simply, and a switching instruction for switching the focus items can be quickly transmitted to the processor to execute the instruction for switching the items, so that the cost is saved.
In step S13, the processor switches the focus item displayed on the in-vehicle screen according to the switching instruction, and performs the audio prompt through the speaker, wherein the audio prompt includes: switching a prompt tone and/or voice broadcasting.
In the embodiment, according to the received switching instruction, the processor switches the focus item in the vehicle-mounted screen, displays the process of switching the focus item through the vehicle-mounted screen, and performs voice prompt through controlling the loudspeaker to prompt the user whether to successfully switch the focus item or prompt the content of the current focus item. For example: according to the switching instruction, when the focus item is successfully switched, the successful switching of the focus item is prompted through a prompt tone or voice broadcast of the successful switching; or when the prompt tone for successful switching is sent, the name of the current focus item is broadcasted through voice so as to prompt the user that the switching is successful.
In an implementation scenario, when the current focus item is the last item in the vehicle-mounted screen and switching cannot be performed according to a switching instruction for switching the next item to be the focus item, the processor sends a switching failure prompt tone or voice broadcast through the loudspeaker to prompt a user that switching fails.
In one embodiment, the rotation speed of the joystick or the dial controller is obtained based on the position change of the joystick or the dial controller. When the rotating speed is smaller than the preset switching speed, performing voice broadcast on the current focus item through a loudspeaker; and when the rotating speed is greater than or equal to the preset switching speed, the voice broadcasting is not carried out. Through voice broadcast focus project name, the user need not to watch on-vehicle screen, alright know current focus project name through pronunciation, help driving safety. For example: the preset switching speed is one degree of rotation per second, and according to the rotation speed of the user for using the rocker or the dial controller, when the rotation speed of the user is smaller than one degree of rotation per second, the name of the current focus item is broadcasted through voice broadcast. When the rotating speed of the user is larger than or equal to one degree of rotation per second, voice broadcasting is not carried out, and the situation that the user is interfered to quickly switch focus items is avoided. In another embodiment, after the current focus item is subjected to voice broadcast through a loudspeaker, when switching is performed, a prompt tone is used for prompting a user, and the currently broadcasted focus item is successfully or unsuccessfully switched.
In an implementation scenario, a time threshold is preset, after a user starts a rotary rocker or a dial controller, when the speed of the rocker or the dial controller in the preset time threshold is less than a preset switching speed or is static, the name of a current focus item is broadcasted through voice broadcast, and the user can conveniently obtain the content of the current focus item.
In step S14, the joystick or dial controller stops rotating, and a confirmation command is sent to the processor based on the vertical pressing of the button of the joystick or dial controller.
In this embodiment, the user stops rotating the joystick or the dial controller to indicate that the operation of switching the focus is finished, and sends a confirmation instruction for selecting the current focus item as the target item according to an action of pressing a button of the joystick or the dial controller vertically downward, so that the processor executes the content of the target item according to the confirmation instruction. The buttons of the dial controller may be located in the center of the dial controller or other easy-to-operate areas, and are not limited in this disclosure.
In step S15, the processor confirms the current focus item of the in-vehicle screen as the target item based on the confirmation instruction, and executes the target item.
In this embodiment, after receiving the confirmation instruction, the processor executes the currently selected focus item, where the selected focus item is the target item. According to the confirmation instruction of the user, the execution is carried out, and the project execution is more efficient.
Through the embodiment, when the user selects the target item, the focus item in the vehicle-mounted screen can be switched and the target item can be confirmed by controlling the steering wheel and combining the acquired voice prompt without paying attention to the vehicle-mounted screen, so that safe driving is facilitated.
In one embodiment, the vehicle-mounted item selection method further comprises: directly slide to predetermineeing the direction from the initial position based on rocker or dial controller remove, send the corresponding preset instruction of predetermineeing the direction to the treater, wherein, predetermine the instruction and include one or more in the following instruction: cancel instructions, switch instructions, return instructions or trigger voice instructions; the processor executes the operation corresponding to the preset instruction based on the preset instruction. For example: and if the rocker or the dial controller is directly dialed upwards or downwards from the initial position, the processor executes a switching instruction to switch the previous or next focus item. When the rocker or the dial controller is dialed to the left, the processor executes a return instruction and returns to the previous focus item or the previous instruction. When the rocker or the dial controller is dialed to the right, the processor executes a triggering voice command and can issue the voice command aiming at the current focus item.
Based on the same invention idea, the disclosure also provides a steering wheel.
