In this embodiment, the execution subject may be a precise navigation system of the vehicle.
The target vehicle may be a new energy vehicle that uses a precise navigation system of the vehicle and needs navigation during driving.
The vehicle driving information may be a parameter for indicating various driving conditions of the target vehicle during driving, and may include, but is not limited to, a vehicle speed, road information, and road conditions. The vehicle travel information may also include navigation information for the target vehicle, such as the length of navigation, the direction of navigation.
Specifically, after the execution subject acquires the vehicle travel information of the target vehicle, a travel route map may be calculated from the vehicle information. The driving route map is used for indicating a fitting route from the current position of the target vehicle to a navigation indicated destination, and the driving route map can be further associated with specific parameters such as real-time vehicle speed, vehicle body position, road condition information and the like. The driving route map may be a guiding map for guiding the target vehicle to drive according to the specified driving route.
Optionally, the executing body may generate an initial driving route according to the navigation information of the target vehicle in the vehicle driving information, and then, in combination with parameters indicating various driving conditions of the target vehicle in the driving process in the vehicle driving information, correct the initial driving route to obtain the driving route map. For example, according to the road condition information indicated by the vehicle driving information, the correct lane and the future lane change condition of the target vehicle should be determined in combination with the initial driving route.
The vehicle travel information may include navigation information for the target vehicle, where the navigation information may be a navigation route signal for guiding the target vehicle to travel from the current position to the destination. The initial driving route can determine the optimal driving route from the current position to the destination according to a plurality of priority ordering modes such as distance priority, time priority and the like, and the initial driving route is obtained. And then, the execution main body can further analyze the vehicle running information to obtain the real-time speed, the vehicle body position and the road condition information of the target vehicle, and then, according to the parameters, the initial running route is corrected to obtain the running route taking the lane as granularity, namely, the target running route is obtained. And then fitting according to the target driving route to obtain a driving route map. The execution main body can learn the mapping relation between the historical parameters such as the vehicle speed, the vehicle body position, the road condition information and the like and the driving route in advance, and can read the driving route information adapted to the current parameters based on the mapping relation when the route is corrected, then match the driving route information with the initial driving route, and directly reselect the driving route for the initial driving route which is not matched. For the matched initial driving route, lane guiding information can be further determined according to the current parameters, and the lane guiding information is merged into the initial driving route to obtain the target driving route.
Then, the execution body can project the driving route pattern onto the front windshield of the target vehicle so as to intuitively display the navigation condition through the front windshield. Optionally, the execution body may further control the projection of the driving route pattern into a specified area of a front windshield of the target vehicle, so as to intuitively display the navigation condition without interfering with the driving sight of the driver.

The first pattern category may correspond to a route pattern for guiding traffic on a highway, a route pattern for guiding traffic on a straight road, and a route pattern for guiding traffic on a curved road. The second pattern category may correspond to a route pattern for guiding traffic in a lane change situation or a route pattern for guiding traffic in a curve situation.
Wherein, for the first pattern category, if the target vehicle is detected to deviate from the lane, deviation guide information may be output according to deviation data of the target vehicle. The offset data may include distance offset data and angle offset data. The distance deviation data is the distance difference between the current position of the target vehicle and the correct position in the driving route map, and the angle deviation data is the angle difference between the current position of the target vehicle and the correct position in the driving route map. The deviation guide information is guide information for instructing the target vehicle to adjust the traveling angle and traveling direction and travel to the correct position.
For the second mode category, the non-driving lane may be displayed in the driving route map. The non-driving lane is a lane in which the driving route indicates not to drive in. The marker display may be to display the non-driving lane as a fork.
In this embodiment, after the navigation is started, the intelligent cabin controller may display the whole navigation map and the navigation route, in the driving process, the intelligent cabin controller transmits the navigation route (length, direction, road information, etc.) signal to the head-up display controller in real time, the instrument transmits the real-time vehicle speed to the head-up display controller in real time, the automatic driving controller transmits the vehicle body position and road condition information to the head-up display controller through the gateway controller, the head-up display controller receives the information, and then projects the fitted driving route diagram onto the front windshield according to calculation, and the driving route has a first mode category and a second mode category according to the vehicle speed and the direction crossing.

The pre-driving route can be the driving variation track of the lane change or the driving variation track of the turning.
For the first mode category, a straight driving route with a guiding arrow in a driving route map and a real-time vehicle speed can be projected to a designated area of a front windshield of a target vehicle. The guiding arrow may be an arrow pointing to the far end of the straight line direction of the straight line driving route. The target vehicle may initially adjust the distance offset as well as the angular offset based on the straight line travel path with the guide arrow. And, the guiding arrow may assist in calculating the offset distance and the offset angle, generating offset guiding information. The target vehicle may further adjust the distance offset and the angle offset based on the offset guidance information.
