Description
Technical Field
The invention belongs to the technical field of driving navigation, and particularly relates to a HUD dynamic navigation method for a complex turnout junction.
Background
Map navigation software such as Gaode and Baidu is applied to the field of driving, and transportation travel of people is facilitated to a great extent. The application of the current navigation system on the vehicle is roughly divided into three types, namely, the navigation software is opened by using a mobile phone for navigation, the central control display screen is installed in the vehicle and the navigation software is used for navigation, and the HUD projector is additionally installed on a vehicle central control console and is combined with the navigation software for navigation.
The former two navigation modes are realized by the fact that the sight of a driver leaves a front road and is transferred to a mobile phone or a central control display screen in the driving process. When the sight line of a driver leaves a front road and focuses on a mobile phone or a central control display screen, visual distraction easily occurs, so that the lane keeping capability of a vehicle is damaged. The third mode of navigating by using the HUD effectively avoids the visual distraction of the driver. However, the conventional HUD-based navigation is static, that is, navigation information is only displayed on a windshield in front of a driver, which has good effect in general steering and lane changing environments, but cannot play a good navigation role at a turnout, especially when more than two turnouts are provided for searching a complex interchange ramp, and the like, and thus problems such as navigation errors are easy to occur.

Detailed Description
The embodiments and effects of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, the HUD dynamic navigation method for a complex turnout of the present invention is implemented according to the following steps:
the front fork information is the position of a fork closest to the vehicle in front of the driving direction of the vehicle and road condition information;
specifically, a GPS navigation system provided in the vehicle is directly used to acquire vehicle position information in real time, and provide driving route information, specific position information of a crossroad (a crossroad closest to the vehicle) entrance to which the vehicle is about to face, and road condition information. The vehicle speed sensor is also directly applied to a vehicle speed sensor which is arranged on a transmission and arranged on the vehicle and is used for acquiring the speed v of the vehicle; the information that gathers in with speed sensor, the vehicle navigation through vehicle OBD interface transmits HUD projection mechanism.
specifically, the HUD projection means determines, according to a running route preset by the vehicle and road condition information at the intersection, a center point of a lane on which the vehicle is going to run at the intersection ahead of the vehicle as a running position of the vehicle at the intersection. And connecting the center point of the lane at the front turnout of the vehicle with the center point of the vehicle to form a dynamic lane dividing navigation indicating line which changes along with the change of the position of the vehicle.
Referring to fig. 2, the principle of the change of the dynamic lane-dividing navigation indicator line is:
(1) the projected arrow points to the middle position of the entrance section of the turnout in the driving route at any moment.
(2) The projected arrow is a straight arrow.
(3) The projected arrow size should be constant in the driver's line of sight.
And 3, determining the initial projection time of the dynamic lane-dividing navigation indication line, and when the vehicle runs to the initial projection time, projecting the dynamic lane-dividing navigation indication line to the road surface in front of the vehicle by the HUD projection mechanism so as to guide the driver to drive into a correct turnout.
Specifically, the determining of the initial projection time of the dynamic lane navigation indicator line specifically includes:
firstly, setting a turnout display threshold value as t, and calculating a real-time linear distance d between a vehicle and the turnout;
secondly, calculating the time t1 required by the vehicle to reach the turnout junction according to the real-time speed of the vehicle;
finally, whether t1 meets the condition that t1 is t is judged, and if yes, t1 is the initial projection time of the dynamic lane-dividing navigation indicator line.
The start time t1 at which the HUD projection means starts projecting an arrow or a character is determined by the speed v of the vehicle and the distance d between the vehicle and the entrance of the turnout. The higher the speed of the vehicle, the larger the value of d at the start of projecting the arrow and the character. The crossing display threshold t is set to ensure that the driver has sufficient reaction time and operating time to enter the crossing. Give the electronic control module at inception time t1 instruction, control HUD projector and open, HUD projector sends out the arrow and the simple character of accurate sign direction of travel between vehicle and fork entry.
The HUD projection mechanism comprises a data processor, an electric control module and a HUD projector; the data processor is used for receiving the position, the speed and the front turnout information of the vehicle acquired in real time, comparing the position, the speed and the front turnout information with a preset running route of the vehicle, judging whether the vehicle faces the turnout, giving out the lane dividing navigation indicating line information at the current moment and transmitting the information to the electric control module; the electric control module is used for controlling the HUD projector to send out an arrow and characters which correctly represent a driving route when a vehicle is about to face a turnout, namely a dynamic lane-dividing navigation indicating line; the HUD projector is used for projecting dynamic lane-dividing navigation indication lines, namely dynamically-changed arrows and characters of driving routes, in front of the vehicle.
The data processor gives the electronic control module an instruction at the starting time t1 to control the HUD projector to be started, and the HUD projector sends out an arrow and simple characters which correctly represent the traveling direction between the vehicle and the turnout entrance.
HUD projection mechanism throws the road surface in vehicle the place ahead with dynamic lane navigation pilot line, specifically is: according to the projection principle of the HUD projection mechanism, the projection direction of the HUD projector is adjusted, and the projection light ray outlet is aligned to the front road surface of the sight of a driver.
The arrow and the character projected by the HUD projection mechanism are used for a driver to accurately know the position of an entrance when a driving route is at a turnout, and the position of the arrow only depends on the position of a vehicle and the position of the entrance of the turnout and is irrelevant to an actual road. The starting position of the arrow is at the HUD projector, and the ending position is at the crossing entrance position of the driving route, as shown in fig. 3 and 4, it can be seen that the present invention can perform accurate crossing navigation for both simple crossings (fig. 3(a) and (b)) and complex crossings (fig. 3(c) and 4).
In the process of vehicle continuous driving, the position of the arrow and the character projected by the HUD projector is constantly changed, and the arrow always points to the entrance of the turnout. When the vehicle-mounted navigation system identifies that the vehicle has correctly passed through the turnout junction, the HUD projector automatically closes the dynamic projection.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
