Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve the technical problems, the embodiment of the invention provides a leading type vehicle navigation method. Fig. 1 shows a flow diagram of a guided vehicle navigation method according to one embodiment of the invention. Referring to fig. 1, the method includes at least steps S102 to S108.
Step S102, acquiring own vehicle geographic position data and target geographic position data of a vehicle.
Step S104, determining leading geographical position data of a virtual leading vehicle based on the electronic map data, the own vehicle geographical position data and the target geographical position data, wherein the virtual leading vehicle is positioned at a specific distance in front of the vehicle.
Step S106, leading navigation data of the virtual leading vehicle is generated based on the electronic map data, the leading geographic position data and the target geographic position data.
Step S108, projecting the image of the virtual lead vehicle to the front windshield of the vehicle, and controlling the display of the image of the virtual lead vehicle on the front windshield based on the lead navigation data.
In the embodiment of the invention, after the leading geographic position data of the virtual leading vehicle is determined based on the electronic map data, the geographic position data of the host vehicle and the target geographic position data, the leading navigation data of the virtual leading vehicle can be generated based on the electronic map data, the leading geographic position data and the target geographic position data, and the image of the virtual leading vehicle is projected on the front windshield of the vehicle, so that a vehicle driver can directly follow the image of the virtual leading vehicle projected on the front windshield of the vehicle to drive without selecting a road according to a navigation arrow or listening to voice navigation information, thereby not only ensuring effective vehicle driving guidance, but also enhancing the sense of reality of leading vehicle navigation. In addition, the display of the image of the virtual lead vehicle on the front windshield is controlled according to the lead navigation data of the virtual lead vehicle, so that a driver can intuitively know the current state of the virtual lead vehicle, and the running state of the virtual lead vehicle is timely adjusted according to the current state of the virtual lead vehicle, and the running experience of the driver is improved. Further, by projecting the image of the virtual leading vehicle on the front windshield of the vehicle, the driver can be effectively ensured to watch the front of the vehicle to a larger extent, and the driving safety of the driver is ensured.
Referring to step S102, in an embodiment of the present invention, in order to obtain the geographic location data of the vehicle, the GPS positioning system of the vehicle may be used to position the vehicle and generate the geographic location data of the vehicle, so as to directly obtain the geographic location data of the vehicle. In addition, before the leading vehicle navigation starts, the user typically inputs a destination to be reached, and therefore, by collecting the navigation destination input by the user and generating target geographic position data corresponding to the destination, the target geographic position data of the vehicle can be obtained.
Referring to step S104, in an embodiment of the present invention, in determining the leading geographical position data of a virtual leading vehicle based on the electronic map data, the geographic position data of the host vehicle and the target geographic position data, in order to ensure that the virtual leading vehicle and the host vehicle are on the same driving route, the driving route of the vehicle to be driven may be determined based on the electronic map data, the geographic position data of the host vehicle and the target geographic position data. Furthermore, based on the own vehicle geographic position data and the determined driving route, the leading geographic position data of the virtual leading vehicle is determined on the driving route of the vehicle.
The virtual lead vehicle is used as a lead navigation vehicle of the host vehicle and is positioned at a specific distance in front of the host vehicle. In an alternative implementation, a specific distance in front of the vehicle of the virtual leading vehicle is set to be L, and the specific distance is calculated in a manner of l=v×t, where V is the current speed of the vehicle, and t is time 1 second. In this embodiment, the specific distance L of the virtual lead vehicle from the host vehicle increases as the current vehicle speed V of the host vehicle increases, and decreases as the current vehicle speed V of the host vehicle decreases. Therefore, when the speed of the vehicle is higher, more time can be reserved for the driver to judge the driving, so that the driver can be effectively prevented from walking by mistake, and the driving safety of the driver is ensured to a certain extent. In this embodiment, t may also take other time values, which are not particularly limited in the embodiment of the present invention.
In addition, in order to ensure that the virtual lead vehicle can provide more effective lead navigation for a vehicle driver, a specific distance L is usually set to be not less than 5 meters, and even if the current speed of the vehicle is slower, the virtual lead vehicle can be ensured to have a distance in front of the vehicle of not less than 5 meters, so that enough driving judgment time is provided for the driver.
In another embodiment, the specific distance L between the virtual leading vehicle and the vehicle may be a certain distance, that is, the specific distance may not change with the current speed of the vehicle.
In the embodiment of the invention, since the virtual lead vehicle is located at a specific distance in front of the host vehicle, the lead geographic position of the virtual lead vehicle is different from the actual running geographic position of the host vehicle by a specific distance. And subsequently, when the virtual lead vehicle is utilized to provide navigation service for the driver of the vehicle, the lead navigation is also performed based on the lead geographic position data of the virtual lead vehicle.
Referring to step S106 above, in an embodiment of the present invention, lead navigation data for the virtual lead vehicle is generated based on the electronic map data, the lead geographic position data of the virtual lead vehicle, and the target geographic position data. And then, the virtual lead vehicle is controlled to perform corresponding driving by utilizing the lead navigation data in the follow-up process, namely, the virtual lead vehicle performs driving according to the lead navigation data generated for the virtual lead vehicle, so as to realize lead navigation of the vehicle. The driver of the vehicle can conveniently drive the vehicle by following the running path of the virtual leading vehicle.
Referring to step S108 above, in an embodiment of the present invention, projecting an image of a virtual lead vehicle onto a front windshield of a vehicle may employ a head Up digital Display (HUD) to project the image of the virtual lead vehicle onto the front windshield of the vehicle. There are a variety of positions for the head up digital display to project an image of the virtual lead vehicle onto the front windshield. For example, an image of the virtual lead vehicle is projected at a position in the middle of the front windshield. For another example, an image of the virtual lead vehicle is projected at a position where the front windshield is facing downward with respect to the direction in which the driver is facing. Thus, the driver can see the image of the virtual lead car without having to lower his head, thereby avoiding distraction of the driver. In addition, the image of the virtual leading vehicle on the front windshield can not influence the driving sight of the driver, so that the driving safety of the driver is ensured.
Of course, the image of the virtual lead vehicle may be projected at other positions of the front windshield of the vehicle, which is not particularly limited in the embodiment of the present invention.
In the embodiment of the invention, in order to facilitate the driver to clearly know the current geographic position of the virtual leading vehicle and other nearby road information so as to determine the geographic position and the road information of the vehicle, the electronic map can be projected onto the front windshield of the vehicle, and the image of the virtual leading vehicle is positioned at the corresponding position of the electronic map according to the leading geographic position data of the virtual leading vehicle, so that the driver can know the geographic position and the road information of the vehicle to be driven in by visually seeing the position of the virtual leading vehicle.
With continued reference to step S108 above, it has been described above that the virtual lead vehicle is controlled to perform corresponding "traveling" according to the lead navigation data, and the "traveling" process of specifically controlling the virtual lead vehicle may be embodied by controlling the display of the image of the virtual lead vehicle on the front windshield by the lead navigation data. In an embodiment of the present invention, the image of the virtual lead vehicle may include a body image, a left turn signal image, a right turn signal image, and the like of the virtual lead vehicle. In this embodiment, there may be various ways of controlling the display of the image of the virtual lead vehicle on the front windshield based on the lead navigation data. The process of steering the navigation data to control the image of the virtual lead car is described in a preferred embodiment.
When the leading navigation data indicate left turning of the virtual leading vehicle, the longitudinal center line of the vehicle body image of the virtual leading vehicle on the front windshield is adjusted to incline to the left by a certain angle so as to display the left turning gesture of the vehicle body image, and meanwhile, the left steering lamp image of the virtual leading vehicle on the front windshield is controlled to periodically flash and display, so that the attention of a driver is highly drawn, and the driver is reminded of making corresponding driving adjustment on the vehicle.
The manner of controlling the left or right turn of the virtual lead vehicle with respect to the lead navigation data may also be, for example, that only the left turn signal image or the right turn signal image periodically blinks when the lead navigation data indicates the left or right turn of the virtual lead vehicle. For another example, when the lead navigation data indicates a left turn or a right turn of the virtual lead vehicle, only the left turn signal image or the right turn signal image is changed in color. For another example, when the lead navigation data indicates that the virtual lead vehicle turns left or right, only the longitudinal centerline of the body image of the virtual lead vehicle is adjusted to be inclined left or right. The embodiment of the invention does not limit the display mode of the image of the virtual lead vehicle in particular.
In another embodiment of the present invention, the image of the virtual lead vehicle may further include a brake light image, and if the virtual lead vehicle is instructed to decelerate according to the lead navigation data in the course of performing the above step S108, the body image of the virtual lead vehicle may be gradually enlarged on the front windshield of the vehicle and the brake light image may be continuously displayed, thereby prompting the vehicle driver to control the vehicle that he drives to decelerate in a more direct manner. This embodiment can also control the color change of the brake light image in the process of continuously displaying the brake light image, which can be more easily brought to the attention of the driver.
In combination with the above embodiment, when the vehicle speed of the host vehicle increases, it can be inferred that the specific distance of the virtual lead vehicle from the host vehicle increases, and at this time, the vehicle body image of the virtual lead vehicle may also be controlled to be gradually reduced on the front windshield of the vehicle. Accordingly, when the vehicle speed of the host vehicle decreases, it can be inferred that the specific distance from the virtual lead vehicle to the front of the vehicle decreases, and at this time, the vehicle body image of the virtual lead vehicle can be controlled to be gradually enlarged on the front windshield of the vehicle. Thus, by controlling the enlargement and reduction of the vehicle body image of the virtual lead vehicle on the front windshield, the distance between the host vehicle and the virtual lead vehicle can be fed back to the driver to a certain extent.
The embodiment of the invention also provides a leading vehicle navigation method, and fig. 2 shows a schematic structural diagram of the leading vehicle navigation method according to another embodiment of the invention. Referring to fig. 2, the method includes at least steps S202 to S210.
Step S202, acquiring own vehicle geographic position data and target geographic position data of a vehicle.
Step S204, based on the electronic map data, the own vehicle geographic position data and the target geographic position data, the leading geographic position data of a virtual leading vehicle is determined, wherein the virtual leading vehicle is located at a specific distance in front of the vehicle.
Step S206, generating leading navigation data of the virtual leading vehicle based on the electronic map data, the leading geographic position data and the target geographic position data.
Step S208, collecting road condition information including obstacles in front of the vehicle, congestion in front of the vehicle, accidents in front of the vehicle and red lights at the intersection in front of the vehicle.
In this step, the collected road condition information may be used to indicate the driving state of the virtual lead vehicle later. For example, virtual lead vehicle braking may be indicated based on road condition information such as obstacles in front of the vehicle, congestion in front of the vehicle, accidents in front of the vehicle, red lights at the intersection in front of the vehicle, etc.
In addition, the process of collecting road condition information can be realized by pre-installing a camera at the front end of the vehicle, so that the process of collecting road condition information is more convenient.
Step S210, projecting an image of the virtual lead vehicle to a front windshield of the vehicle, and controlling display of the image of the virtual lead vehicle on the front windshield based on the lead navigation data and the road condition information.
In this step, the image of the virtual lead vehicle includes a vehicle body image and a brake light image of the virtual lead vehicle. For example, when road condition information such as an obstacle in front of a vehicle, congestion in front of the vehicle, an accident in front of the vehicle, red light at a road junction in front of the vehicle and the like is collected, the virtual leading vehicle can be indicated to brake according to the road condition information, and then the virtual leading vehicle can be stopped at a corresponding position of a road in front. Accordingly, the body image of the virtual lead vehicle is gradually enlarged on the front windshield, and the brake light image is continuously displayed. The process of continuously displaying the brake light image may also control the color change of the brake light image to be more noticeable to the driver.
For another example, the collected road condition information is that a green light exists at the intersection in front of the vehicle, and the virtual leading vehicle can be indicated to directly pass through the intersection in front according to the collected road condition information, so that the size of a vehicle body image of the virtual leading vehicle on the front windshield is unchanged. For another example, the collected road condition information is that the front of the vehicle is unobstructed, and the virtual leading vehicle can be indicated to accelerate through the front intersection according to the collected road condition information, and correspondingly, the vehicle body image of the virtual leading vehicle is gradually reduced on the front windshield of the vehicle.
Therefore, the embodiment of the invention collects the actual road condition information of the running of the vehicle through the camera or other image collecting equipment arranged on the vehicle, so that the running of the virtual lead vehicle can be controlled by combining the actual road condition information. For road condition information which can not be seen by a driver of the vehicle and can be acquired by a camera or other image acquisition equipment, the driver can clearly know the road condition information through the image of the virtual leading vehicle on the front windshield of the vehicle, and then corresponding driving judgment is made.
For a specific description of step S202 to step S206, reference may be made to the above embodiments, and the description thereof will be omitted.
