For example, the GPS coordinates of the vehicle may be acquired by a GPS (Global Positioning System) function in the vehicle, and the area where the vehicle is located may be detected, and when the area where the vehicle is located is detected as a parking lot, the map data of the parking lot where the vehicle is located may be called.
In an embodiment of the present invention, determining the first parameter information according to the map data may be the following sub-steps:

And 104, correcting the vehicle according to the correction information.

Referring to fig. 2, a flowchart illustrating steps of another vehicle modification method according to an embodiment of the present invention is provided, which may specifically include the following steps:
step 201, obtaining map data;
step 202, acquiring positioning information of a vehicle;
step 203, determining road identification information corresponding to the positioning information;
after the positioning information of the vehicle is obtained, the current position information of the vehicle can be determined according to the positioning information in the map, and then the road information corresponding to the position information in the map data can be determined, wherein the road information can include road identification information.
For example, when the vehicle travels on the a road, after the positioning information of the vehicle is acquired, the current position information of the vehicle may be determined according to the positioning information in the map, and then the road information corresponding to the position information may be determined, and the road identification information a in the road information may be determined, and it may be determined that the vehicle is currently traveling on the a road.
Step 204, determining first parameter information corresponding to the road identification information from the map data; the first parameter information may be first slope angle information;
after determining the road identification information, first parameter information corresponding to the road identification information may be determined from the map data.
For example, after determining the road identification information, the slope angle information of the road corresponding to the road identification information may be acquired from the map data, and then the average slope angle information of the road may be calculated, and the average slope angle information may be determined as the first slope angle information.
Step 205, determining second parameter information acquired by the vehicle; wherein the second parameter information may be second slope angle information;
after determining the first slope angle information, second parameter information collected by the vehicle itself may be determined.
For example, the bank angle information of the vehicle may be collected by the IMU, and then the bank angle information of the vehicle corresponding to the road may be determined, and the average bank angle information of the vehicle may be calculated to determine the average bank angle information as the second bank angle information.
Step 206, determining correction information aiming at the vehicle slope angle according to the first slope angle information and the second slope angle information;
after the first slope angle information and the second slope angle information are determined, the first slope angle information and the second slope angle information can be compared and analyzed, difference values between information collected by the vehicle and map data can be obtained, and then correction information for the slope angle of the vehicle can be determined according to the difference values.
For example, a difference value between the first slope angle information and the second slope angle information may be calculated, and a difference value between the average slope angle of the road and the average slope angle of the vehicle may be obtained, and a correction amount for the slope angle of the vehicle may be determined based on the difference value, and the correction amount may be determined as the slope angle correction information of the vehicle.
And step 207, correcting the vehicle according to the correction information.
After the correction information of the vehicle is determined, the slope angle of the vehicle may be corrected in accordance with the correction amount for the slope angle of the vehicle in the correction information.
For example, the correction information of the vehicle slope angle may be calculated to obtain a correction amount of the vehicle slope angle, and then the vehicle longitudinal automatic control may be corrected according to the correction amount, such as an IMU pitch angle correction, a velocity correction, and an acceleration correction, so that an influence caused by a difference value between the first slope angle information and the second slope angle information may be compensated.
The vehicle longitudinal automatic control may be control for the throttle or brake of the vehicle.
In the embodiment of the invention, the positioning information of the vehicle is obtained by obtaining the map data, the road identification information corresponding to the positioning information can be determined, and determining first parameter information corresponding to the road identification information and second parameter information acquired by the vehicle from the map data, wherein the first parameter information may be first slope angle information, the second parameter information may be second slope angle information, further, correction information for the vehicle inclination angle may be determined based on the first inclination angle information and the second inclination angle information, and according to the correction information, the vehicle is corrected, automatic correction of the vehicle slope angle by combining map data is achieved, accuracy of the vehicle slope angle is improved, potential safety hazards caused by the fact that the vehicle slope angle is not corrected timely are avoided, and safety of the vehicle is improved.
Referring to fig. 3, a flowchart illustrating steps of another vehicle modification method according to an embodiment of the present invention is provided, which may specifically include the following steps:
step 301, obtaining map data;
step 302, acquiring positioning information of a vehicle;
after the positioning information of the vehicle is obtained, the current position information of the vehicle can be determined according to the positioning information in the map, and then the road information corresponding to the position information in the map data can be determined, wherein the road information can include road identification information.
For example, when the vehicle is traveling on the a road, after the positioning information of the vehicle is acquired, the current position information of the vehicle may be determined according to the positioning information in the map, and then the road information corresponding to the position information may be determined, and the road identification information a in the road information may be determined, and it may be determined that the vehicle is currently traveling on the a road
Step 303, determining vehicle track information corresponding to the positioning information;
after the positioning information of the vehicle is obtained, the current position information of the vehicle can be determined according to the positioning information in the map, and then the vehicle track information corresponding to the position information can be determined.
For example, since the vehicle is constantly moving, the position information determined in the map may be a line, which may be represented as trajectory information of the vehicle, and thus the line corresponding to the position information may be determined as trajectory information of the vehicle.
For example, after determining the road identification information, the slope angle information of the road corresponding to the road identification information may be acquired from the map data, and then the average slope angle information of the road may be calculated, and the average slope angle information may be determined as the first slope angle information
Step 304, determining first parameter information corresponding to the vehicle track information from the map data; wherein, the first parameter information may be track length information;
after determining the vehicle trajectory information, first parameter information corresponding to the vehicle trajectory information may be determined from the map data.
For example, a ratio for calculating the vehicle trajectory information may be determined from the map data, and the vehicle trajectory information may be calculated based on the ratio, and the trajectory length information of the vehicle may be obtained, and the trajectory length information may be determined as the first parameter information.
Step 305, determining second parameter information acquired by the vehicle; wherein the second parameter information may be vehicle mileage information.
After determining the track length information, second parameter information collected by the vehicle itself may be determined.
For example, the mileage of the vehicle may be measured by using a speedometer in the vehicle, and the vehicle mileage information may be obtained and determined as the second parameter information.
After the first slope angle information and the second slope angle information are determined, the first parameter information and the second parameter information are compared and analyzed, the difference between the information collected by the vehicle and the map data can be obtained, and then the correction information aiming at the slope angle of the vehicle can be determined according to the difference.
For example, a difference between the first slope angle information and the second slope angle information may be calculated, and a difference between the average slope angle of the road and the average slope angle of the vehicle may be obtained, and a correction amount for the slope angle of the vehicle may be determined based on the difference, and the correction amount may be determined as the slope angle correction information of the vehicle
Step 306, determining correction information aiming at the radius of the wheel according to the track length information and the vehicle mileage information;
after determining the track length information and the vehicle mileage information, a comparative analysis may be performed on the track length information and the vehicle mileage information.
In actual driving, because the wheels are affected by factors such as motion load, vehicle load, and road rigidity, an elastic deformation phenomenon may occur, which may further cause the radius of the wheels to become smaller, further cause an error in the driving distance measured by the vehicle itself, and may cause the actual driving distance of the vehicle to be different from the driving distance measured by the vehicle itself, that is, there is a difference between the track length information and the vehicle mileage information.
Further, after the track length information and the vehicle mileage information are compared and analyzed, a difference value between the information collected by the vehicle and the map data can be obtained, and then the correction information for the wheel radius can be determined according to the difference value.
Specifically, a difference value between the track length information and the vehicle mileage information may be calculated, a correction amount for the wheel radius may be determined according to the difference value, and the correction amount may be determined as the wheel radius correction information.
For example, if the current wheel rotation speed is 1000 rpm and the wheel radius is 250 mm, the travel distance measured when the vehicle travels for 1 minute may be about 1.57 km, and the track length information determined according to the map may be 1.50 km, so that the difference between the actual travel distance of the vehicle and the travel distance measured by the vehicle itself may be obtained, the difference may be 0.07 km, the difference may be calculated according to the rotation speed and the travel time, and the calculation result may be determined as the correction information for the wheel radius.
After the correction information of the vehicle is determined, the slope angle of the vehicle may be corrected in accordance with the correction amount for the slope angle of the vehicle in the correction information.
Step 307, correcting the vehicle according to the correction information.
After the correction information of the vehicle is determined, the wheel radius may be corrected in accordance with the correction amount for the wheel radius in the correction information.
For example, the correction amount of the wheel radius may be obtained from the correction information of the wheel radius, and then the automatic control in the longitudinal direction of the vehicle may be corrected according to the correction coefficient, such as the wheel rotation speed correction and the steering wheel deviation correction, and further the influence caused by the deviation of the wheel radius may be compensated.
In the embodiment of the invention, the positioning information of the vehicle is obtained by obtaining the map data, the vehicle track information corresponding to the positioning information can be determined, the first parameter information corresponding to the vehicle track information is determined from the map data, and the second parameter information acquired by the vehicle is determined, wherein the first parameter information can be track length information, the second parameter information can be vehicle mileage information, the correction information aiming at the wheel radius can be further determined according to the track length information and the vehicle mileage information, the vehicle can be corrected according to the correction information, the automatic correction of the wheel radius by combining the map data is realized, the accuracy of the wheel radius is improved, the potential safety hazard caused by the fact that the wheel radius is not corrected in time is avoided, and the safety of the vehicle is improved.

4, acquiring road information corresponding to the positioning information, and calculating the road information;
in practical application, the current road information of the vehicle can be determined according to the positioning information in the map, so that map data corresponding to the current road information can be acquired, and the road information can be calculated to determine the first parameter information.
The road information may include slope angle information, the first parameter information may be first slope angle information, and the first slope angle information may be average slope angle information of a current road in a map.
5, collecting vehicle slope angle information and calculating vehicle average slope angle information;
