Problems solved by technology

[0002] At present, when driving on a road with strong sunlight, sunglasses are mainly used to avoid the inability to observe the road conditions well or short-term blindness caused by excessive sunlight.
However, the driver may forget to put the sunglasses in the vehicle, so that the sun glasses are not always present in the vehicle
In addition, especially when the driver is driving from an urban road to a rural, intercity or inter-provincial road without building shelter, it is easy to relax his vigilance. When turning, he may face the sun directly, and the sudden strong light will cause short-term blindness, thereby Causing traffic accidents, threatening the lives of drivers and other personnel

example 1

[0053] Example 1: Obtain the local longitude and latitude twice through the GPRMC protocol of GNSS, so that two points of the vehicle traveling on the earth can be obtained, and the current direction of the vehicle can be obtained by connecting these two points to make a straight line, that is, Determine the current direction of travel according to the latitude and longitude change information of the vehicle.

example 2

[0054] Example 2: It needs to be explained in advance that the inertial measurement unit can include acceleration sensors, gyroscopes and geomagnetic sensors. Generally, an inertial measurement unit includes three single-axis acceleration sensors, three single-axis gyroscopes and a geomagnetic Sensor, the acceleration sensor detects the acceleration signal of the independent three-axis of the object in the carrier coordinate system, the gyroscope detects the angular velocity signal of the carrier relative to the navigation coordinate system, the geomagnetic sensor can be used to detect the existence of the vehicle and the vehicle type identification, and the inertial measurement unit can measure the vehicle's Relative positioning information, that is, the trajectory and posture of the self body relative to a certain starting position from a certain moment. That is, the current direction of travel is determined from the measurement results of the inertial measurement unit of the...

Abstract

The invention discloses a vehicle and a control method and device thereof. The control method comprises the steps: obtaining the azimuth angle and the altitude angle of the sun; acquiring a current traveling direction and a predicted traveling direction of the vehicle; and adjusting the light flux of the front windshield of the vehicle according to the azimuth angle, the altitude angle, the current traveling direction and the predicted traveling direction. According to the control method of the vehicle, no matter whether a driver wears sunglasses or not, the driving safety cannot be affected by too strong sunlight, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle control method, a vehicle control device and a vehicle with the control device. Background technique [0002] At present, when driving on a road with strong sunlight, sunglasses are mainly used to avoid the inability to observe road conditions well or short-term blindness caused by excessive sunlight. However, the driver may forget to put the sunglasses in the vehicle, so that the sunglasses are not always present in the vehicle. In addition, especially when the driver is driving from an urban road to a rural, intercity or inter-provincial road without building shelter, it is easy to relax his vigilance. When turning, he may face the sun directly, and the sudden strong light will cause short-term blindness, thereby Causing traffic accidents and threatening the lives of drivers and other personnel. [0003] Therefore, under the situation that there is no sunglasses in...
