Detailed Description
The invention is further described below with reference to the accompanying drawings of the specification:
the invention provides a navigation enhancement display device based on a high-precision map, which comprises:
a central controller; steering wheel buttons, a vehicle-mounted front-mounted camera, a vehicle-mounted navigation device, a high-precision map device, a vehicle-mounted positioning instrument, a vehicle-mounted display and a vehicle-mounted loudspeaker which are respectively connected with the central controller. The vehicle-mounted front-mounted camera outputs front road condition information in a first preset distance range in front of the vehicle to the central controller, and provides the front road condition information in the first preset distance range in front of the vehicle to the high-precision map device. The vehicle navigation is used for setting a destination by a driver, and the vehicle positioning instruments (RTK and GNSS) are used for providing real-time vehicle positioning information to the high-precision map device and the central controller. The central controller performs decision control and control signal output, and the output decision signal prompts a user through the vehicle-mounted loudspeaker and the vehicle-mounted display.
The central controller receives instructions fed back by a user based on prompt information based on a hard wire signal input by a steering wheel key.
In this embodiment, the driver selects to turn on the navigation-enhanced display function or turn off the navigation-enhanced display function based on the demand. Specifically, the driver turns on or off the function, and the instruction may be input by hardware or may be input on an in-vehicle display. When the navigation enhancement display function is not opened, the navigation enhancement display function is displayed on a display interface of the vehicle-mounted display according to a navigation path output by the vehicle-mounted navigation, namely, the display mode at the moment is consistent with the conventional display mode.
As shown in fig. 2, after the driver turns on the navigation enhancement display function, in this embodiment, the following procedure is performed:
setting destination information by a driver through vehicle-mounted navigation, and planning a navigation path by the vehicle-mounted navigation based on the destination information input by the driver (the process is the prior art);
the high-precision map device monitors road information within 2km in front of the vehicle in real time and outputs the following information:
a) The merging situation within 2km (second predetermined distance range) in front of the vehicle, specifically,: first information of whether the vehicle has a lane in front of 2 km.
b) The ramp condition within 2km (second predetermined distance range) ahead of the vehicle, specifically: and whether second information of the ramp exists within 2km in front of the vehicle.
c) Third information including a total number of lanes at a current position of the vehicle and a total number of lanes at 2km ahead of the vehicle travel; for example, the total number La of lanes, lane ID, 1 from left to right, of the current position of the vehicle is accumulated; the total number of lanes Lb at a position 2km ahead of the vehicle travel, the lane ID, 1 from left to right, is accumulated.
d) And fourth information including a speed limit value of a current position of the vehicle and a speed limit value at a second preset distance position in front of the vehicle.
And the central controller judges whether a parallel road demand or a down ramp demand exists in a range of 2km in front of the vehicle running according to a navigation path provided by the vehicle navigation.
If yes, the central controller specifically needs third information in the road information based on the road information provided by the high-precision map device, the third information is used for identifying the number change of the lanes and judging whether the current lane of the vehicle is a depletion lane or not; if the lane where the vehicle is located is not the extinction lane, controlling the vehicle-mounted display to display according to a navigation interface provided by the original vehicle-mounted navigation; if the current lane of the vehicle is the extinction lane, outputting first prompt information for reminding a driver of lane change through the vehicle-mounted display and the vehicle-mounted loudspeaker. After the driver confirms through the steering wheel key based on the first prompt information, the central controller judges the lane changing possibility according to the lane changing track provided by the high-precision map device and the real-time detection of the surrounding environment by the vehicle-mounted front-mounted camera, and always detects the surrounding environment. The high-precision map device is used for planning a lane change track according to a navigation path, changing the distance between lanes by combining the curvature of the road of the lane and the curvature of the target lane, and fitting a vehicle track equation to calculate a running track. And the central controller also controls the vehicle-mounted display popup window scene reconstruction interface to display the recommended lane change track so as to guide the driver to change lanes.
As shown in fig. 3, the vehicle is traveling in the rightmost lane L3, and the high-precision map device detects that the front of the vehicle is in front of the lane where the front of the lane is dying, i.e., lb < La, and a lane change is required (the vehicle is traveling in the dying lane, i.e., the vehicle has a need to merge into the arterial road). A represents the current position of the vehicle, B represents the intersection point of the lane changing track of the vehicle and two lanes, C represents the final centering of the vehicle to the target lane position point after lane changing, so the actual lane changing process is as follows:
a represents the current position of the vehicle, B represents the intersection point of the lane changing track of the vehicle and two lanes, C represents the final centering of the vehicle to the target lane position point after lane changing, so the actual lane changing process is as follows:
1) A- > B: the high-precision map device locates an initial lane change point B according to a running track equation and plans a running track curve LAB;
2) B- > C: the central controller controls the vehicle to enter a target lane (namely a main road to which the vehicle needs to enter), and the vehicle position is continuously corrected according to the running track of the vehicle.
3) And when the vehicle is kept parallel to the lane for 0.5s, the display interface of the vehicle-mounted display is retracted to the navigation interface.
If the ramp exists, namely a ramp outlet (Lb is larger than La) exists on the navigation path, the central controller judges whether a deceleration lane communicated with the ramp exists or not based on the navigation path; if a deceleration lane exists, judging whether the current lane of the vehicle is a target lane communicated with the deceleration lane or not based on the high-precision map device; if the current lane of the vehicle is not the target lane communicated with the speed reduction lane, the central controller controls the vehicle-mounted display and the vehicle-mounted loudspeaker to output second display information for reminding the driver of lane change; after the driver confirms through the steering wheel key, the central controller controls the vehicle-mounted controller bullet window to display the track of the ramp according to the speed limit value of the ramp, and the vehicle-mounted controller bullet window directly enters the speed reduction lane from the target lane communicated with the ramp, and then enters the ramp. If the speed reduction lane does not exist, the central controller controls the vehicle-mounted controller bullet window to display according to the ramp speed limit value.
