The following is a detailed description of how the control module controls the main and sub mirrors according to the driver's state information and the driving state of the vehicle.
According to the utility model discloses an embodiment, control module basis driver's state information to main rear-view mirror control module with vice rear-view mirror control module sends control command, include:
sending a control instruction to the main rearview mirror control module and the auxiliary rearview mirror control module according to the face orientation and the eye focus of a driver and the driving direction and the driving speed of the vehicle, wherein when the driving direction of the vehicle is straight line driving, the angle of the main rearview mirror on the corresponding side relative to the vehicle body is increased according to the face orientation and the eye focus according to a first preset speed, and the angle of the auxiliary rearview mirror relative to the vehicle body is decreased according to a second preset speed; when the driving direction of the vehicle is turning driving, increasing the angle of the main rearview mirror and the auxiliary rearview mirror on the same side of the turning relative to the vehicle body according to a third preset speed, and reducing the reverse side of the turning according to a fourth preset speed; and when the driving direction of the vehicle is reverse driving, reducing the angle of the auxiliary rearview mirror relative to the vehicle body according to the face direction at a fifth preset speed, and controlling the main rearview mirror to be downwards adjusted relative to the horizontal direction of the vehicle body.
The first preset speed, the second preset speed, the third preset speed, the fourth preset speed and the fifth preset speed can be calibrated according to actual conditions, for example, the first preset speed, the second preset speed, the third preset speed, the fourth preset speed and the fifth preset speed are related to the running speed of the vehicle, and the faster the speed is, the greater the first preset speed to the fifth preset speed are.
Specifically, in the vehicle starting driving stage, when the vehicle is started, the human face is firstly detected, and if the human face recognition result shows that a corresponding driver exists, the main and auxiliary rearview mirrors are automatically adjusted to the state that the driver is accustomed to; if the face recognition result indicates that no corresponding driver exists, the main rearview mirror and the auxiliary rearview mirror are adjusted to be in a universal state, and then corresponding records are generated according to the adjustment result of the driver.
When the vehicle is in a normal driving stage, acquiring data related to a driving state through a vehicle body attitude sensor, wherein the data comprises the following steps: the driving direction, the vehicle speed, the acceleration and the yaw rate, and the state data of the driver are acquired through a binocular camera: the moving direction of human eyes and the orientation of human faces are used for automatically adjusting the main rearview mirror and the auxiliary rearview mirror according to the parameters.
Example one: when the driving direction of the vehicle is straight line driving, the main rearview mirror and the auxiliary rearview mirror are automatically adjusted according to the face orientation and the eye detection. For example, the face of a person faces slightly to the left, the focus of the eyes of the person faces the left rearview mirror, and the driver wants to observe the road condition on the rear side, the main rearview mirror is slightly unfolded outwards, and the auxiliary rearview mirror is slightly folded inwards, so that the included angle of the auxiliary rearview mirror relative to the vehicle body is ensured to be unchanged; if the human face continues to incline left, the auxiliary rear-view mirror slightly contracts inwards, so that the included angle between the auxiliary rear-view mirror and the vehicle body is reduced, and a better view in the inner side of the vehicle is provided. Generally, the angle between the sub-rear-view mirror and the vehicle body is between 45 degrees and 75 degrees.
Example two: when the vehicle turns to the right, the right main and auxiliary rearview mirrors automatically extend outwards, and the left main and auxiliary rearview mirrors slightly retract inwards; similarly, when the vehicle turns left, the left main mirror and the right sub-mirror automatically extend outward, and the right main mirror and the right sub-mirror slightly retract inward. The faster the vehicle speed, the faster the adjustment speed of the main mirror and the sub-mirror.
Example three: when the driving direction of the vehicle is reverse, according to the face direction detection result, when the face faces to the left, the left main rearview mirror slightly turns downwards, meanwhile, the left auxiliary rearview mirror is folded inwards, the larger the face direction rotating angle is, the larger the inward folding amplitude of the left auxiliary rearview mirror is. The same reason, when people's face towards the right, the main rear-view mirror in right side overturn slightly down, and the vice rear-view mirror in right side is received inwards simultaneously, and people's face is towards the pivoted angle big more, and the vice rear-view mirror in right side is received inwards's range big more to provide better field of vision for the driver, avoid the blind area.
To sum up, the utility model discloses an intelligent regulating system of vehicle rearview mirror adopts the two-stage framework of major-minor rear-view mirror for the driver obtains good rear and side field of vision simultaneously; a face detection function based on deep learning is added, and the main rearview mirror and the auxiliary rearview mirror can be automatically adjusted according to each driving habit; and the main and auxiliary rearview mirrors are adjusted in real time according to the vehicle body attitude sensor and the driving state, so that the visual field obtained by the driver is optimal.
