Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In order to solve the problem that the conventional navigation technology cannot provide reliable navigation according to the actual driving environment, in one embodiment, as shown in fig. 1, a driving navigation method is provided, which includes the following steps:
step S110, acquiring ADAS information acquired by an ADAS system of the vehicle and a map layer of a vehicle navigation map; the ADAS information includes one or any combination of the following information: lane information, traffic sign information, road condition information, vehicle distance information, blind area information, and vehicle information.
It should be noted that, each step of the driving navigation method of the present application is executed on the vehicle-mounted computer.
The ADAS system uses various sensors (including millimeter wave radar, laser radar, single/binocular camera, satellite navigation, etc.) mounted on a vehicle to sense the surrounding driving environment in real time and collect data during the driving process of the vehicle, and can also identify, detect and track static and dynamic objects. In the application, the navigation map is reconstructed by using the ADAS information acquired by the ADAS system. The vehicle-mounted navigation map is stored in a database of the vehicle, a map layer used for navigation at the current moment is extracted from the vehicle-mounted navigation map, and the map layer is used for reconstructing the navigation map. The map layer at least comprises a road graph of the road where the vehicle is located and a direction indicating graph for navigation, and in one example, the road graph is a simulation graph drawn according to the road where the vehicle is located.
The lane information is used for describing lane characteristics and comprises lane line information, lane type information and lane line distances, wherein the lane line information is used for describing line types such as solid lines, dotted lines, road center lines, bus line special lane lines and the like and also describing the positions of all lane lines; the lane type information is used for describing road types such as straight roads, curved roads, turnout roads, circular roads and the like; the lane line distance is used to describe the distance between the side of the vehicle and the lane line.
The traffic sign information is used for describing traffic sign types such as speed limit signs, cross signs, tunnel signs, turning signs and the like. The road condition information is used to describe the road condition around the vehicle, such as surrounding vehicles, pedestrians, obstacles, and whether there are potholes on the road surface. The vehicle distance information is used for describing the distance between the vehicle and the adjacent vehicle, including the distance between the vehicle and the front adjacent vehicle, the distance between the vehicle and the left adjacent vehicle, the distance between the vehicle and the right adjacent vehicle and the distance between the vehicle and the rear adjacent vehicle. The blind area information is used to describe the conditions within the range of the vehicle's blind area, including whether there is an obstacle, whether there is a pedestrian, and whether there is a vehicle. The vehicle information is used to describe the running state of the vehicle, including the vehicle speed, steering, and the like.
And step S120, generating a corresponding auxiliary display element according to the ADAS information, and fusing the auxiliary display element into the layer to obtain the layer to be displayed.
The auxiliary display element is an auxiliary graphic inserted into the layer in step S110, and is used for providing an auxiliary driving prompt. And generating lane line auxiliary display elements of the lane lines on the two sides according to information (including types of the lane lines and distances from the vehicles to the lane lines on the two sides respectively) for describing the lane lines on the two sides of the lane where the vehicles are located in the lane information, and inserting the lane line auxiliary display elements into the road graph in the layer to prompt the lane lines on the two sides of the lane where the vehicles are located. In one example, the lane line auxiliary display elements include lane lines on both sides of a lane in which the vehicle is located, a vehicle model, and distance values of the vehicle to the lane lines on both sides.
Generating a traffic sign auxiliary display element according to the traffic sign information, and inserting the traffic sign auxiliary display element into the layer, for example, if the acquired traffic sign information is described as a speed limit sign, generating a corresponding speed limit sign auxiliary display element to be inserted into the layer, if the acquired traffic sign information is described as a road narrowing sign, generating a road narrowing sign auxiliary display element to be inserted into the layer, if the acquired traffic sign information is described as a tunnel sign, generating a tunnel sign auxiliary display element to be inserted into the layer. Furthermore, if multiple traffic signs are identified at the same time, multiple corresponding traffic sign auxiliary display elements can be inserted into the map layer at the same time. In one example, a traffic sign auxiliary display element may be disposed above a layer of the layer display state.
If the road condition information comprises information for describing pedestrians, generating a pedestrian auxiliary display element to be inserted into a corresponding position in the map layer, wherein in one example, the pedestrian auxiliary display element comprises a vehicle model, a pedestrian model, a position of the pedestrian relative to the vehicle and a distance value from the vehicle; if the road condition information comprises information for describing the obstacles, generating an obstacle auxiliary display element to be inserted into a corresponding position in the map layer, wherein in one example, the obstacle auxiliary display element comprises a vehicle model, an obstacle model, a position of the obstacle relative to the vehicle and a distance value from the vehicle; and if the road condition information comprises information for describing the hollow, generating a hollow auxiliary display element to be inserted into a corresponding position in the map layer, wherein the hollow auxiliary display element comprises a vehicle model, a hollow model, the position of the obstacle relative to the vehicle and a distance value from the vehicle in one example. Furthermore, if the road condition information includes information describing pedestrians, obstacles and potholes at the same time, auxiliary display elements of the pedestrians, the obstacles and the potholes can be inserted into the map layer at the same time.
And generating a vehicle distance auxiliary display element according to the vehicle distance information, and displaying the distance between the vehicle and the adjacent vehicle, specifically, the distance between the vehicle and the adjacent vehicle comprises the distance between the vehicle and the adjacent vehicle in front, the distance between the vehicle and the adjacent vehicle on the right side, the distance between the vehicle and the adjacent vehicle on the left side and the distance between the vehicle and the adjacent vehicle on the rear side. In one example, the information to be avoided from being displayed is excessive, the distance of the front adjacent vehicle can be preferentially displayed, and the distances of other directions can be displayed only when the distance is smaller than the safety value.
And if the blind area information comprises information for describing pedestrians, vehicles and obstacles, generating a blind area auxiliary display element so as to prompt that the pedestrians, the vehicles and/or the obstacles exist in the vehicle blind area. In one example, generating the blind spot assistance display element includes a pedestrian model, a vehicle model, and/or an obstacle model, an orientation relative to the vehicle, and a distance value from the vehicle.
In one example, in order to avoid displaying too much information, the driver may receive the information too much at a moment and interfere with the driving decision, and miss the opportunity to deal with the situation with higher risk level in time, so that if multiple auxiliary display elements appear at the same moment, the higher priority is preferentially displayed according to the priority level. Sorting according to the vehicle speed and the emergency, wherein the specific priority is as follows: the method comprises the steps of self-adaptive cruise workshop time distance, front anti-collision emergency braking, front anti-collision secondary early warning, front anti-collision early warning, lane deviation warning, lateral blind area detection warning, lateral rear blind area warning, radar warning, navigation lane-changing intersection, navigation road condition and map display.
Step S130, transmitting the layer to be displayed to the liquid crystal instrument panel, so that the liquid crystal instrument panel displays the layer to be displayed.
In an example, the layer to be displayed is displayed in a central display area of the liquid crystal instrument panel.
In each embodiment of the driving navigation method, ADAS information acquired by a vehicle ADAS system and a map layer of a vehicle navigation map are acquired; generating a corresponding auxiliary display element according to the ADAS information, and fusing the auxiliary display element into the layer to obtain the layer to be displayed; the driving navigation method integrates ADAS information acquired by an ADAS system on a vehicle into a vehicle-mounted navigation map, generates a navigation map combined with a real driving environment, and displays the navigation map by the liquid crystal instrument panel, so that navigation can be provided for driving according to the real driving environment, and a prompt of the current driving environment is provided for a driver in real time, so that the navigation is more reliable.
In one embodiment, as shown in fig. 2, the driving navigation method further includes the steps of:
step S240, when the driving parameter of the vehicle obtained according to the ADAS information exceeds the safe driving parameter range, the display state of the layer to be displayed is changed; the driving parameters comprise one or any combination of the following parameters: vehicle distance, vehicle speed, lane line distance, pedestrian distance, and obstacle distance.
It should be noted that the ADAS information is processed to obtain the driving parameters of the vehicle, the obtained driving parameters are compared with the safe driving parameters, and if the driving parameters exceed the safe driving parameter range, the display state of the layer to be displayed is changed to remind safe driving. In one example, when the driving parameters of the vehicle obtained according to the ADAS information exceed the safe driving parameter range, the liquid crystal instrument panel can be controlled to flash to remind the driver of safe driving. In another example, when the driving parameters of the vehicle obtained according to the ADAS information exceed the safe driving parameter range, the voice system on the vehicle can be controlled to perform voice broadcast prompting so as to perform safe driving prompting. In yet another example, the ADAS system is activated to assist driving when a driving parameter of the vehicle derived from the ADAS information is outside a safe driving parameter range. The safe driving parameters are configured in the vehicle-mounted computer in advance.
The following will be described in detail with reference to specific scenarios:
in one embodiment, when the driving parameter of the vehicle obtained according to the ADAS information exceeds the safe driving parameter range, the step of transforming the display state of the layer to be displayed further includes the steps of:
when the lane line distance is smaller than the preset lane line distance value, carrying out color replacement processing on the lane line auxiliary display elements, and fusing the lane line auxiliary display elements after color replacement into the map layer; the lane line auxiliary display element is generated according to lane line information in the lane information;
or
And when the lane line distance is smaller than the preset lane line distance value, carrying out color replacement processing on the lane line auxiliary display elements, fusing the lane line auxiliary display elements with the replaced colors into the layer, and controlling the liquid crystal instrument panel to carry out local amplification display on the position between the vehicle on the layer to be displayed and the lane line closest to the vehicle.
In this embodiment, the lane line distance refers to a distance from the vehicle to a solid line of the lane where the vehicle is located, and when the lane line distance is smaller than a preset lane line distance value, it indicates that the vehicle deviates from the lane in the direction of the solid line, at this time, the current color of the lane line auxiliary display element is changed, for example, from the current green to the red, or from the current white to the red. In one example, when the lane line distance is smaller than a preset lane line distance value, the lane line auxiliary display element is controlled to flash in the layer to be displayed so as to give a safe driving prompt.
Further, in order to enable the driver to more clearly understand the condition between the vehicle and the lane line closest thereto (the solid line in this embodiment), the condition between the vehicle and the lane line closest thereto is displayed in a partially enlarged manner according to the image information between the vehicle and the lane line closest thereto collected by the ADAS system.
In another embodiment, when the driving parameter of the vehicle obtained according to the ADAS information exceeds the safe driving parameter range, the step of transforming the display state of the layer to be displayed further includes the steps of:
when the vehicle distance is smaller than the preset vehicle distance value, carrying out color replacement processing on the vehicle distance auxiliary display element, and fusing the vehicle distance auxiliary display element after color replacement into the map layer; the vehicle distance auxiliary display element is generated according to the vehicle distance information;
or
And when the vehicle distance is smaller than the preset vehicle distance value, carrying out color replacement processing on the vehicle distance auxiliary display element, fusing the vehicle distance auxiliary display element after color replacement into the map layer, and controlling the liquid crystal instrument panel to carry out local amplification display on the position between the vehicle on the map layer to be displayed and the nearest adjacent vehicle.
It should be noted that, when the vehicle distance is smaller than the preset vehicle distance value, it is determined that the vehicle is too close to the adjacent vehicle, and there is a risk of collision. In one example, when the vehicle distance is smaller than a preset vehicle distance value, the vehicle distance auxiliary display element is controlled to flash in the layer to be displayed so as to give a safe driving prompt.
In another embodiment, when the driving parameter of the vehicle obtained according to the ADAS information exceeds the safe driving parameter range, the step of transforming the display state of the layer to be displayed further includes the steps of:
when the vehicle speed exceeds the speed limit value in the traffic sign information, controlling the speed limit auxiliary display element to flash on the layer to be displayed; the auxiliary speed limit display element is generated according to the traffic sign information.
It should be noted that, if the current vehicle speed of the vehicle exceeds the speed limit value of the lane where the vehicle is located, the speed limit auxiliary display element is controlled to flash on the layer to be displayed, so that the speed limit auxiliary display element is flash-displayed on the liquid crystal instrument panel. In one example, when the vehicle speed exceeds the speed limit value in the traffic sign information, the color of the speed limit auxiliary display element is replaced, and the speed limit auxiliary display element after color replacement is merged into the map layer.
In each embodiment of the driving navigation method, the dangerous condition of the vehicle is safely reminded in a corresponding mode so as to improve the driving safety of the vehicle.

It should be noted that, in the driving process of the vehicle, different types of roads are necessarily required, and when it is judged that the vehicle encounters a tunnel, a branch road, a loop road, a bridge and other roads according to the lane information of the ADAS information, the road section is enlarged and displayed, so that the driver can more accurately recognize the road. Furthermore, voice broadcasting can be carried out on the road through a vehicle voice system.
In each embodiment of the driving navigation method, the road is locally displayed in an enlarged manner, so that the driving navigation method is helpful for a driver to judge road conditions, assists the driver to make a correct driving decision, and avoids driving into a wrong road.
