[0053] Those skilled in the art will appreciate that the structure shown in FIG1 does not constitute a limitation on the driving path off-vehicle display device, and may include more or fewer components than shown, or a combination of certain components, or a different arrangement of components.

[0056] An embodiment of the present application provides a method for displaying a driving path outside a vehicle. Referring to FIG. 2 , FIG. 2 is a flow chart of a first embodiment of the method for displaying a driving path outside a vehicle.

[0057] In this embodiment, the method for displaying the driving path outside the vehicle includes the following steps:

[0058] Step S10: Acquire the planned driving path of the vehicle to be displayed, and determine the coordinate information corresponding to each path point in the planned driving path.

[0059] At present, with the development of science and technology, people's dependence on intelligent driving for travel is gradually increasing, and functions such as automatic low-speed vehicle control are gradually entering people's lives, such as automatic reversing and parking.

[0060] However, in the existing automatic vehicle control process, pedestrians outside the vehicle are unaware of the vehicle's driving path and may easily enter the driving path by mistake. If the vehicle does not recognize them in time, they may be injured, resulting in low safety.

[0061] Therefore, in order to solve the above defects, this embodiment can display the planned driving path outside the vehicle for pedestrians to observe and prevent them from entering by mistake. Compared with the existing situation where pedestrians outside the vehicle cannot understand the vehicle's driving path, this embodiment improves safety.

[0062] The method of this embodiment can be applied in the context of automated vehicle control. The execution entity of this embodiment can be a computing service device with off-board driving path display, network communication, and program execution capabilities, such as a car with multiple off-board display units. It can also be other electronic devices that perform the same or similar functions. This embodiment and the following embodiments will be described below using the aforementioned off-board driving path display device (hereinafter referred to as the device).

[0063] The above-mentioned off-vehicle display unit can be a unit for displaying a path, and the above-mentioned vehicle to be displayed can be a vehicle that needs to be displayed off-vehicle. Several of the above-mentioned off-vehicle display units can be installed on the above-mentioned vehicle to be displayed. For ease of understanding, reference can be made to Figures 3 and 4 for explanation. Figure 3 is a top view schematic diagram of the path display in the off-vehicle display method of the driving path of the present application, and Figure 4 is a side view schematic diagram of the path display in the off-vehicle display method of the driving path of the present application; as shown in Figure 3, several off-vehicle display units can be installed in front and rear of the vehicle to be displayed. The several off-vehicle display units in the front can constitute a first off-vehicle display module, and the several off-vehicle display units in the rear can constitute a second off-vehicle display module, wherein K1, K2, K3 and K4 are the extreme positions for installing the first or second off-vehicle display module. The specific installation position and the specific number of off-vehicle display units can be set according to actual conditions, and this embodiment does not impose any restrictions on this.

[0064] In Figure 3, the path corresponding to the forward movement can be displayed on the ground through the first external display module, where W is the width corresponding to the displayed path. The path corresponding to the backward movement can be displayed through the second external display module, and the width can be the same as the path corresponding to the forward movement, and both can be the width of the vehicle body.

[0065] As shown in Figure 4, the ground clearance height of the first external display module can be h1, and its own height can be h2. The ground clearance height of the second external display module can be h3, and its own height can be h4. The specific heights can be set according to actual conditions, among which h1 can be the same as h3, and h2 can be the same as h4.

[0066] Continuing with Figure 4, the path length displayed on the ground by the first external display module can be L1, that is, the distance AB in Figure 4, and the path length displayed on the ground by the second external display module can be L2, that is, the distance CD in Figure 4, where L1 and L2 can both be set by adjusting the illumination angle and number of external display units. The larger the illumination angle, the longer the distance, the more external display units there are, the longer the distance, and the clearer the path.

[0067] The above-mentioned planned driving path can be a driving path pre-planned by the vehicle to be displayed. For example, if the user needs the vehicle to be displayed to automatically reverse into the garage, after the user determines the corresponding parking space, the vehicle to be displayed can plan a driving path based on its own position and the location of the parking space as the above-mentioned planned driving path. Then, the vehicle can drive according to the planned driving path to complete the reverse parking.

[0068] Among them, the planned driving path can be composed of several path points. For ease of understanding, refer to Figure 5, which is a schematic diagram of the planned driving path in the off-vehicle display method of the driving path of this application. As shown in Figure 5, if the vehicle to be displayed is automatically reversing into the garage and needs to travel from the EF position to the HG position, then the paths corresponding to EG and FH are the above-mentioned planned driving paths. The four line segments FG, GH, HF and FE can all be composed of several path points, and each path point can correspond to a coordinate information. In this embodiment, the center position of the vehicle to be displayed can be used as the origin to construct a rectangular coordinate system, and then the corresponding coordinate information can be generated according to the position corresponding to each path point.

[0069] In a specific implementation, the above-mentioned device can obtain the planned driving path of the vehicle to be displayed, determine the path points in the planned driving path, construct a rectangular coordinate system based on the center position of the vehicle to be displayed, and determine the coordinate information corresponding to each path point based on the rectangular coordinate system.

[0070] Step S20: determining the to-be-displayed number corresponding to each piece of coordinate information based on a preset mapping relationship, wherein the to-be-displayed number is the number corresponding to the off-vehicle display unit.

[0071] The above-mentioned preset mapping relationship can be the relationship between coordinate information and the corresponding number to be displayed. In this embodiment, an LED light can be provided in the external display unit, and the path can be projected onto the ground by the LED light. In order to facilitate the control of the corresponding external display unit for display, each external display unit can be numbered. For ease of understanding, it can be explained with reference to Figure 6. Figure 6 is a structural schematic diagram of the external display unit in the external display method of the driving path of the present application. As shown in Figure 6, the first external display module and the second external display module in this embodiment can both be composed of m*n external display units, where m units can be set in a row in the horizontal axis direction and n units can be set in a column in the vertical axis direction. The projection width of each external display unit is k, that is, k1...k in Figure 4. m , the projection length of each exterior display unit is j, i.e. j1, j2...j in Figure 4 n The specific value can be adjusted according to the actual situation, and this embodiment does not limit this.

[0072] The above-mentioned device can construct the above-mentioned preset mapping relationship in advance based on the correspondence between the position of each external display unit projected on the ground and the coordinate information of the position. The specific steps are as follows:

[0073] Before the step of obtaining the planned driving path of the vehicle to be displayed, the method further includes:

[0074] Step S01: obtaining the display area corresponding to each of the vehicle exterior display units, and determining the coordinate information corresponding to each of the display areas;

[0075] Step S02: Obtain the serial number corresponding to each of the exterior vehicle display units, and construct a preset mapping relationship based on each of the coordinate information and the corresponding serial number.

[0076] The above-mentioned display area can be the corresponding area projected onto the ground by the external display unit. In this embodiment, the display area projected by all external display units can be divided in advance to obtain corresponding rectangular frames. Each rectangular frame can correspond to one or more coordinate points. If it corresponds to one coordinate point, one number to be displayed corresponds to one coordinate information. If it corresponds to multiple coordinate points, one number to be displayed can correspond to multiple coordinate information, and then the above-mentioned preset mapping relationship can be constructed based on the coordinate information and the corresponding number.

[0077] In a specific implementation, the above device may determine the to-be-displayed number corresponding to each piece of coordinate information based on a preset mapping relationship.

[0078] Step S30: Displaying the planned driving path outside the vehicle via the vehicle's outside display unit corresponding to the number to be displayed.

[0079] In a specific implementation, after determining the number to be displayed, the above-mentioned device can control the external display unit corresponding to the number to be displayed to light up, and display the corresponding planned driving path outside the vehicle.

[0080] Furthermore, considering that it is less practical to display the planned driving path outside the vehicle when the vehicle speed is high, in this embodiment, before the step of obtaining the planned driving path of the vehicle to be displayed, the method further includes:

[0081] Step S001: obtaining the current speed of the vehicle to be displayed, and determining whether the current speed is lower than a preset speed threshold;

[0082] Step S002: If yes, execute the step of obtaining the planned driving path of the vehicle to be displayed.

[0083] The above-mentioned preset vehicle speed threshold can be a threshold used to determine whether the current vehicle speed is too high, and can be set according to actual conditions. That is, in this embodiment, the above-mentioned device can obtain the current vehicle speed of the vehicle to be displayed, and determine whether the current vehicle speed is lower than the preset vehicle speed threshold. If so, it means that the vehicle to be displayed is in a low-speed driving state, and it can be displayed outside the vehicle. If not, it means that the vehicle to be displayed is in a high-speed driving state, and displaying outside the vehicle may affect the driver's driving. At the same time, pedestrians outside the vehicle generally do not appear on high-speed roads. Therefore, the above-mentioned device may not display, saving energy while improving practicality.

[0084] The above-mentioned device can also select the time to start the external display according to user needs, that is, the external display can be performed when the user manually drives the vehicle to be displayed, or when the vehicle to be displayed is automatically controlled, or the external display can be performed only when the vehicle is automatically controlled; if it is performed during both manual driving and automatic control, the above-mentioned device can display when it detects that the current vehicle speed is lower than the preset speed threshold; if it is performed only during automatic control, the above-mentioned device can detect whether the vehicle to be displayed is in the automatic control state. If so, it will then detect whether the current vehicle speed is lower than the preset speed threshold.

[0085] The above-mentioned device of this embodiment can pre-acquire the display area corresponding to each off-vehicle display unit, and establish a preset mapping relationship based on the coordinate information corresponding to each display area and the number corresponding to the off-vehicle display unit. In actual use, the above-mentioned device can determine whether the current vehicle speed is lower than the preset vehicle speed threshold. If so, it can obtain the planned driving path of the vehicle to be displayed, and determine the path points in the planned driving path. A rectangular coordinate system is constructed based on the center position of the vehicle to be displayed, and the coordinate information corresponding to each path point is determined based on the rectangular coordinate system. The number to be displayed corresponding to each coordinate information is determined based on the preset mapping relationship, and the planned driving path is displayed outside the vehicle through the off-vehicle display unit corresponding to the number to be displayed. Since this embodiment can display the planned driving path outside the vehicle for pedestrians to observe and prevent them from entering by mistake, compared with the existing situation where pedestrians outside the vehicle cannot understand the vehicle's driving path, this embodiment improves safety. At the same time, since pedestrians outside the vehicle are prompted with the vehicle's driving path, pedestrians will not enter the driving area, thereby improving the vehicle's driving efficiency.

[0086] Refer to FIG. 7 , which is a flow chart of a second embodiment of a method for displaying a driving path outside a vehicle according to the present application.

[0087] Considering that the number of off-vehicle display units is limited and when the planned driving route is long, the off-vehicle display units may not be able to display all planned driving routes outside the vehicle, so this embodiment can display a portion of the route and update the displayed route in real time according to the current position of the vehicle to be displayed. Specifically, as shown in FIG. 7 , in this embodiment, the above-mentioned step S10 includes:

[0088] Step S11: obtaining a planned driving path of the vehicle to be displayed, and determining a current driving path within a preset distance threshold based on the planned driving path and the current position of the vehicle to be displayed.

[0089] The above-mentioned preset distance threshold can be the farthest distance that the off-vehicle display unit can support display. As shown in Figure 4, the farthest distance that can be displayed for the first off-vehicle display module can be L1, and the farthest distance that can be displayed for the second off-vehicle display module can be L2. The above-mentioned preset distance threshold can be the values ​​corresponding to the above-mentioned L1 and L2, which is not limited in this embodiment.

[0090] The above-mentioned current driving path can be a path that can be displayed by the vehicle to be displayed within the planned driving path. For ease of understanding, the explanation is continued with reference to Figure 5. As shown in Figure 5, if the path corresponding to EF to GH is the above-mentioned planned driving path, but since the distance that can be displayed by the second external display module is L2, the path between EF and IJ can be displayed by the second external display module, and the path between EF and IJ is the above-mentioned current driving path.

[0091] Step S12: determining the coordinate information corresponding to each path point in the current driving path;

[0092] Accordingly, the above step S30 includes:

[0093] Step S31: displaying the current driving path outside the vehicle via the vehicle's outside display unit corresponding to the number to be displayed.

[0094] In a specific implementation, after determining the current driving path, the above-mentioned device can determine the coordinate information corresponding to each path point in the current driving path, and determine the number to be displayed corresponding to each coordinate information based on the mapping relationship, and finally control the display unit corresponding to the number to be displayed to light up, so as to project the current driving path onto the ground for display outside the vehicle, and then the current driving path can be displayed in real time according to the current position.

[0095] In one embodiment, considering that the vehicle to be displayed does not continue to drive after automatically reversing into a parking space, it is sufficient to only display the path to the parking space. Therefore, in this embodiment, after the step of obtaining the planned driving path of the vehicle to be displayed, the method further includes:

[0096] Step S111: determining whether the current driving state of the vehicle to be displayed is a storage state based on the planned driving path;

[0097] The current driving status of the above-mentioned vehicle to be displayed can be divided into a parking state and a regular driving state. If it is in the parking state, it can be said that the vehicle to be displayed is reversing into the parking state. Other driving states except reversing into the parking state can be called the above-mentioned regular driving state. The above-mentioned device can determine whether it is in the parking state according to the destination of the planned driving route. If the destination is a parking space, it is determined to be in the parking state. Of course, it can also be judged by other methods. For example, when the user clicks the automatic parking function button, it can be determined that the purpose of the generated planned driving route is to enter the parking space, and then it can be determined that the vehicle to be displayed is in the parking state.

[0098] Step S112: If yes, then obtain the parking space position of the target parking space, and determine the parking distance between the current position of the vehicle to be displayed and the parking space position;

[0099] Step S113: When the entry distance exceeds a preset distance threshold, executing the step of determining a current driving path within the preset distance threshold based on the planned driving path and the current position of the vehicle to be displayed.

[0100] The above-mentioned device can determine the parking space position of the target parking space from the planned driving path, and determine the parking distance between the current position and the parking space position, where the target parking space can be the parking space that the user needs to park in, and judge whether the parking distance exceeds the preset distance threshold. If it exceeds, it means that the parking distance is still long and the external display unit cannot fully display it, and then only the current driving path within the preset distance threshold can be displayed.

[0101] In one embodiment, after the step of determining the parking distance between the current position of the vehicle to be displayed and the parking space position, the method further includes:

[0102] Step S114: When the entry distance does not exceed the preset distance threshold, the entry distance is used as the preset distance threshold, and the step of determining the current driving path within the preset distance threshold based on the planned driving path and the current position of the vehicle to be displayed is executed.

[0103] If the parking distance does not exceed the preset distance threshold, it means that the remaining parking distance is short, and the off-vehicle display unit can fully display it. Since the vehicle to be displayed will stop after parking in the parking space and will not continue to move, the parking distance can be used as the preset distance threshold in real time to display the current driving path between the parking spaces. As shown in Figure 5, if the parking distance does not exceed the preset distance threshold, the second-generation display module only displays the current driving path to the GH position in real time, and will not display anything after HG, which can save power.

[0104] If the current driving state of the vehicle to be displayed is a normal driving state, the current driving path can be directly displayed.

[0105] In this embodiment, the device can obtain the planned driving path of the vehicle to be displayed, determine the current driving path within a preset distance threshold that can be supported for display based on the current position of the vehicle to be displayed, then determine the coordinate information corresponding to each path point in the current driving path, and determine the display number corresponding to each coordinate information based on a mapping relationship. Finally, the display unit corresponding to the display number is controlled to light up, so as to project the current driving path onto the ground for off-vehicle display. In this way, the current driving path can be displayed in real time based on the current position without displaying the entire planned driving path, thereby achieving the purpose of off-vehicle display and reducing the number of off-vehicle display units. At the same time, before performing off-vehicle display, the device can determine whether the current driving state of the vehicle to be displayed is a parking state. If not, the current driving path is directly displayed. If so, based on the parking distance between the current position of the vehicle to be displayed and the parking position of the target parking space, it is determined whether the parking distance exceeds a preset distance threshold. If so, the current driving path within the preset distance threshold is displayed. If not, only the current driving path corresponding to the parking distance is displayed in real time.

[0106] Refer to FIG8 , which is a flow chart of a third embodiment of a method for displaying a driving path outside a vehicle according to the present application.

[0107] In order to facilitate pedestrians outside the vehicle to understand the driving direction of the vehicle to be displayed, as shown in FIG8 , in this embodiment, after the above step of determining the coordinate information corresponding to each path point in the current driving path, the method further includes:

[0108] Step S121: Acquire the current gear position of the vehicle to be displayed, and determine the current driving direction according to the current gear position.

[0109] Accordingly, the above step S31 includes:

[0110] Step S311: Displaying the current driving direction outside the vehicle via the outside-vehicle display unit.

[0111] The above-mentioned current driving direction can be the current driving direction of the vehicle to be displayed. After determining the coordinate information corresponding to each path point, the above-mentioned device can obtain the current gear position of the vehicle to be displayed. If the current gear position is a forward gear position, it can be displayed outside the vehicle in the forward direction and an identifier corresponding to the forward direction can be displayed. If it is a reverse gear position, it can be displayed outside the vehicle in the reverse direction and an identifier corresponding to the reverse direction can be displayed. As shown in Figure 3, if it is a forward gear position, the identifier corresponding to the forward direction (the right arrow in Figure 3) can be displayed through the first external display module. If it is a reverse gear position, the identifier corresponding to the reverse direction (the left arrow in Figure 3) can be displayed through the second external display module. Of course, the specific identifier can also take other forms, and this embodiment does not limit this.

[0112] If the current gear is neither a forward gear nor a reverse gear, the first external vehicle display module or the second external vehicle display module does not display the identifier.

[0123] Based on the first embodiment of the device for displaying a driving path outside a vehicle of the present application, a second embodiment of the device for displaying a driving path outside a vehicle of the present application is proposed.

[0124] In this embodiment, the coordinate determination module 901 is further configured to obtain a planned driving path of the vehicle to be displayed, and determine a current driving path within a preset distance threshold based on the planned driving path and the current position of the vehicle to be displayed; and determine coordinate information corresponding to each path point in the current driving path;

[0125] The path display module 903 is further configured to display the current driving path outside the vehicle via an outside display unit corresponding to the number to be displayed.

[0126] As an embodiment, the coordinate determination module 901 is also used to determine whether the current driving state of the vehicle to be displayed is a parking state based on the planned driving path; if so, the parking space position of the target parking space is obtained, and the parking distance between the current position of the vehicle to be displayed and the parking space position is determined; when the parking distance exceeds the preset distance threshold, the operation of determining the current driving path within the preset distance threshold based on the planned driving path and the current position of the vehicle to be displayed is executed.

[0127] As an embodiment, the coordinate determination module 901 is also used to use the entry distance as the preset distance threshold when the entry distance does not exceed the preset distance threshold, and perform the operation of determining the current driving path within the preset distance threshold based on the planned driving path and the current position of the vehicle to be displayed.

[0128] Based on the above-mentioned embodiments of the device for displaying a driving path outside a vehicle, a third embodiment of the device for displaying a driving path outside a vehicle is proposed.

[0129] In this embodiment, the coordinate determination module 901 is further configured to obtain the current gear position of the vehicle to be displayed, and determine the current driving direction according to the current gear position;
