[0021] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.
[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0024] It is understood that although the terms "first", "second", "third", etc. may be used herein to describe various components, regions, layers and / or parts, these components, regions, layers and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers and / or parts. Therefore, the first component, region, layer and / or part discussed below may be referred to as a second component, region, layer and / or part without departing from some embodiments of the present invention.
[0025] In order to overcome the above-mentioned defects of the prior art, the present invention provides a surround view display control method and device for multi-train vehicles, which are used to automatically control the opening or closing of the surround view display based on the collected vehicle status information after collecting vehicle status information. The original driver's manual switching mode is changed to a standby mode to avoid safety hazards caused by driver distraction.
[0026] Figure 1 The present invention is a flowchart of a surround view display control method for a multi-unit vehicle according to one aspect of the present invention.
[0027] Please refer to Figure 1 The surround view display control method 100 of a multi-train vehicle provided by the present invention may include:
[0028] Step 101: Collect vehicle status information; and
[0029] Step 102: Turning on or off the surround view display based on the vehicle status information, wherein the control instruction to turn off the surround view display has a higher priority than the control instruction to turn on the surround view display.
[0030] Further, preferably, in one embodiment, the vehicle state information may include the vehicle speed and whether the vehicle is currently in a parking relief state or a parking imposition state.
[0031] Accordingly, turning on or off the surround view display based on the vehicle status information may include: turning on the surround view display in response to the vehicle being currently in a parking relief state and the vehicle speed being zero; and turning off the surround view display in response to the vehicle being currently in a parking application state.
[0032] It can be understood that for the first case, when the vehicle is currently in a parking relief state and the speed is zero, it can be judged that the vehicle is in a driving state about to start or about to park. At this time, the driver needs to view the environment around the vehicle through the surround display system to determine whether the vehicle has the conditions for safe starting. Therefore, the surround display is automatically turned on at this time, and the surround screen automatically switches to the HMI main interface to assist the driver in driving.
[0033] In the second case, the vehicle is currently in a parking state, that is, the vehicle is in a parked state. At this time, there is no need to obtain the surrounding environment, the surround display is turned off, and the surround screen automatically exits the HMI main interface. The main interface displays other vehicle information for users to use.
[0034] Furthermore, in a preferred embodiment, in the surround view display method provided by the present invention, the vehicle status information may also include whether the current steering wheel angle of the driver's end exceeds a preset angle.
[0035] Correspondingly, turning on or off the surround view display based on the vehicle status information may also include: turning on the surround view display in response to the current driving end steering wheel angle exceeding the preset angle and the vehicle speed being greater than zero.
[0036] For example, the preset angle can be 60°. When it is detected that the absolute value of the steering wheel angle on the driving end of the vehicle is greater than 60° and the vehicle speed is greater than 0, it can be determined that the vehicle is currently in a turning state. Due to the length characteristics of multi-unit vehicles, it is impossible to observe the entire environment on both sides of the vehicle from the rearview mirror when turning. Therefore, it is necessary to turn on the surround view display so that the surround view screen automatically switches to the HMI main interface to assist the driver in driving.
[0037] At the same time, in a preferred embodiment of the present invention, the vehicle status information may also include the duration that the vehicle is in a certain state.
[0038] Correspondingly, turning on or off the surround view display based on the vehicle status information may also include: in response to the current driving end steering wheel angle not exceeding the preset angle and the vehicle speed being greater than zero, and the duration of the state not reaching the preset time threshold, turning on the surround view display; and in response to the current driving end steering wheel angle not exceeding the preset angle and the vehicle speed being greater than zero, and the duration of the state reaching the preset time threshold, turning off the surround view display.
[0039] For example, the preset angle is still 60°, and the preset time threshold is, for example, 15s. When the absolute value of the steering wheel angle on the driving end of the vehicle is monitored to be less than or equal to 60° and the vehicle speed is greater than 0, the surround view display is turned on and the duration of the vehicle status is monitored at the same time. When the surround view screen pops up for 15s, the surround view display is automatically turned off, the HMI main interface is exited, and other vehicle information is displayed on the main interface.
[0040] It can be understood that the setting of the preset time threshold can further ensure the driving safety after the vehicle starts. Within this time threshold, the vehicle may have just started and needs to be driven out of the garage. At this time, the surrounding situation of the vehicle can be observed through the automatically turned surround display to avoid scratches.
[0041] In addition, in a preferred embodiment, the surround view display control method for a multi-train vehicle provided by the present invention may further include: if the surround view display is turned on or off but cannot be successfully realized, the surround view display is manually controlled by the user. In other words, the surround view display control method provided by the present invention changes the original manual control mode to a standby mode, and when the automatic control provided by the present invention fails or fails, the driver manually controls the surround view display to improve safety performance.
[0042] Figure 2 FIG. 4 is a flow chart of a surround view display control method according to an embodiment of the present invention.
[0043] like Figure 2 As shown, in this embodiment, firstly, step 201 is executed: judging whether the current vehicle speed is zero. If the vehicle speed is zero, step 202 is entered: judging whether the vehicle is currently in a parking relief state. If the vehicle is currently in a parking relief state, step 205 is entered: turning on the surround view display, and the surround view screen is automatically popped up on the HMI; if the vehicle is currently in a non-parking relief state, step 203 is then executed: judging whether the vehicle is currently in a parking application state. If not, step 202 is returned; if yes, step 206 is executed: turning off the surround view display.
[0044] Return to step 201. If the current vehicle speed is not zero, go to step 204: determine whether the absolute value of the steering wheel angle on the driver's side is greater than 60°. If so, go to step 205: turn on the surround view display. If not, that is, the current steering wheel angle on the driver's side is less than or equal to 60°, also turn on the surround view display, and detect the duration of this state at the same time. If the duration reaches 15 seconds, go to step 206: turn off the surround view display.
