[0062] Figure 2This is an embodiment of the present application that can be realized Figure 1 Schematic diagram of electronic equipment for bus sunshade control method shown.

[0064] In order to make the purpose, technical scheme and advantages of the implementation of this application clearer, the technical scheme in the embodiment of this application will be described in more detail below in conjunction with the drawings in the embodiment of this application. In the drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of this application, not all of them. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain this application, and should not be construed as limitations on this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of this application are described in detail below in conjunction with the drawings.

[0065] Figure 1 It is a flowchart of a bus sunshade control method according to an embodiment of the present application.

[0066] like Figure 1 The bus sunshade control method shown includes:

[0067] Step 1: Get sunlight intensity information;

[0068] Step 2: Determine whether the sunshade needs to be adjusted based on the sunlight intensity information. If so,

[0069] Step 3: Obtain vehicle driving information;

[0070] Step 4: Obtain the sunshade that needs to be adjusted according to the vehicle driving information;

[0071] Step 5: Obtain the driver's sight height;

[0072] Step 6: Generate an adjustment signal according to the driver's sight height and vehicle driving information;

[0073] Step 7: Sending an adjustment signal to the sunshade control device in the direction that needs to be adjusted, so that the sunshade control device adjusts the length of the sunshade in the direction that needs to be adjusted according to the adjustment signal.

[0074] In other embodiments, whether the sunshade needs to be adjusted can also be comprehensively judged based on the sunlight angle information and the sunlight intensity information. In some scenarios, although the sunlight intensity is relatively strong, the direction in which the vehicle is traveling may cause the sunlight to be directly above the vehicle. As a result, although the sunlight is very strong, it does not affect the driver's line of sight. At this time, there is no need to adjust the sunshade. Therefore, adjusting the sunlight angle and sunlight intensity can make the adjustment of the sunshade more humane.

[0075] The bus sunshade control method of the present application can determine whether adjustment is needed according to light intensity, and determine which sunshade to adjust and the length of adjustment according to the driver's line of sight and vehicle driving information, thereby realizing automatic opening and closing of the sunshade and control of the opening length. Compared with manual adjustment, the workload of the driver in adjusting the sunshade is greatly reduced, and the safety factor of driving the vehicle is improved.

[0076] In this embodiment, judging whether the sunshade needs to be adjusted according to the sunlight intensity information includes:

[0077] When the sunlight intensity information is greater than a preset sunlight intensity threshold, it is determined that the sunshade needs to be adjusted.

[0078] In the above-mentioned embodiment where the direction of light needs to be considered, when the sunlight intensity information is greater than a preset sunlight intensity threshold, and the direction and angle of light will affect the driver's line of sight, it is determined that the sunshade needs to be adjusted.

[0079] In this embodiment, the sunlight intensity is used to determine whether the sunshade needs to be adjusted. A signal is sent to adjust the sunshade only when the intensity of the sunlight affects safety. When there is insufficient sunlight on rainy days, the driver will not be affected even if there is sunlight, so no adjustment is required.

[0080] In this embodiment, the sunlight intensity may be acquired through a light intensity sensor.

[0081] In this embodiment, multiple light intensity sensors can be set. For example, one light intensity sensor is set to obtain the direction of the driver facing the front windshield, to obtain the sunlight intensity in the driver's driving direction, and another light intensity sensor is used to obtain the sunlight intensity in the side direction of the driver.

[0082] In an embodiment with multiple light intensity sensors, the light intensity sensors can be used directly to determine which sunshade to adjust. For example, on a general bus, the driver has a front sunshade and a side sunshade. However, depending on the driving direction, the driver's side sunshade may be in the shadow due to houses and trees around the road. In this case, no adjustment is required. In this case, different light intensity sensors can be used to select the sunshade that needs to be adjusted, thereby optimizing the adjustment logic.

[0083] In one embodiment, obtaining the sunshade that needs to be adjusted according to the vehicle driving information includes:

[0084] Get the vehicle's driving direction;

[0085] Get current time information;

[0086] Get the current GPS latitude and longitude location information;

[0087] Determine whether the front sunshade needs to be adjusted and / or determine whether the side sunshade needs to be adjusted based on the vehicle's driving direction, current time information, and GPS longitude and latitude location information.

[0088] In this embodiment, obtaining the sunshade that needs to be adjusted according to the vehicle driving information includes:

[0089] Get the vehicle's driving direction;

[0090] Based on the acquired vehicle travel direction, light direction and angle information (in this embodiment, the angle refers to the angle between the light and the horizon), determine whether the front sunshade needs to be adjusted and / or whether the side sunshade needs to be adjusted.

[0091] Specifically, there are two ways to determine how to adjust:

[0092] 1. Judgment by external sensors (main means): External sensors judge the intensity of sunlight, as well as the direction and angle of light. When the intensity is greater than the threshold, the height of the sunshade can be judged according to the line of sight based on the principle that light travels in a straight line, thereby judging whether the sunshade needs to be adjusted. Figure 3 As shown, this method is prior art and will not be described in detail here.

[0093] 2. Determination method through GPS: GPS can locate the user's longitude and latitude, and inertial navigation can understand the direction of the vehicle. The relative relationship between the current longitude and latitude and the sun can be determined through time to obtain the angle of sunlight. Combined with the direction of the vehicle, the angle of sunlight adjustment can be obtained through the parallelogram law. It is recommended to emphasize the method of determining the height of the sunshade through sensors, and use GPS as a supplementary method. Because the first method can deal with all light pollution, such as light pollution from glass curtain walls, pollution caused by high beams in the target lane, etc., and the second method can be used as a supplement after the sensor is effective. Because most vehicles have GPS navigation function.

[0094] In one embodiment, generating an adjustment signal according to the driver's sight height and the vehicle driving information includes:

[0095] Get current time information;

[0096] Get the current GPS latitude and longitude location information;

[0097] Get the current sunlight and horizon angles based on the current time information and the current GPS longitude and latitude location information;

[0098] According to the current sunlight and horizon angles and the driver's sight height, the length of the sunshade in the direction that needs to be adjusted is obtained;

[0099] An adjustment signal is generated according to the length of the sunshade in the direction to be adjusted.

[0100] In this embodiment, generating an adjustment signal according to the driver's sight height and the vehicle driving information includes:

[0101] Get the driver's sight height;

[0102] According to the driver's sight height obtained by the sensor, the length of the sunshade in the direction that needs to be adjusted is obtained;

[0103] An adjustment signal is generated according to the length of the sunshade in the direction to be adjusted.

[0104] In this embodiment, the driver's sight height is acquired through a DMS sensor.

[0105] Specifically, see Figure 3 , the length of the sunshade in the adjustment direction can be obtained by the following method:

[0106] exist Figure 3 In the equation, l1 = h-h1; l2 = l1-h2*tanβ;

[0107] L2 is the length of the sunshade; β is the light angle measured by the light sensor; h is the height of the car; h1 is the height of the driver's line of sight; l1 is the height from the top of the car to the driver's line of sight; h2 is the length from the driver's line of sight to the sunshade; because light travels in a straight line, the angle of the light hitting the sensor is equal to the angle of the light hitting the driver's eyes. The height of the car is fixed, and because the sunshade is also vertical, the driver's line of sight and the sunshade form a trapezoid ABCD. If the length, height and bottom angle of the trapezoid's bottom side are known, the upper side field (sunshade height) can be calculated. The formula for calculating the height of the sunshade is as follows: Sunshade height l2 = l1-h2*tanβ(angle).

[0108] In this way, the length that needs to be adjusted can be determined more accurately.

[0109] In this embodiment, the bus sunshade control method of the present application further includes:

[0110] Get the current sunshade position information;

[0111] Obtain adjustment displacement and movement direction of the sunshade according to the current sunshade position information and the length of the sunshade in the direction to be adjusted;

[0112] Converting the adjustment displacement and the movement direction of the sunshade curtain into an adjustment signal and sending it to a sunshade curtain control device;

[0113] The sunshade control device is adjusted according to the adjustment displacement and the direction of movement of the sunshade.

[0114] In one embodiment, after the adjustment signal is sent to the sunshade control device in the direction to be adjusted, so that the sunshade control device adjusts the length of the sunshade in the direction to be adjusted according to the adjustment signal, the bus sunshade control method further includes:

[0115] Obtaining a user's facial image;

[0116] Get the sunlight recognition classifier;

[0117] Extracting feature information of the user's facial image;

[0118] The feature information is input into the sunlight recognition classifier to obtain classification labels, wherein the classification labels include labels for areas around the eyes where sunlight shines and labels for areas around the eyes where sunlight does not shine.

[0119] In this way, after the adjustment, facial recognition is used to determine whether the sunlight will not directly shine around the driver's eyes. If it is determined that the sunlight will not directly shine around the driver's eyes, it means that the adjustment is successful.

[0120] It can be understood that through the trained sunlight recognition classifier, it is possible to identify whether there is sunlight around the eyes of a person's face. For example, by using the reaction of the face after a large amount of sunlight is irradiated on the face as a training set, the label can be identified, or it can be judged by the brightness of the face after the sunlight is irradiated on the face.

[0121] In one embodiment, the bus sunshade control method further comprises:

[0122] If the label is a label where the sun shines around the eyes, repeat the following steps until the label is a label where the sun does not shine around the eyes:

[0123] Get sunlight intensity information;

[0124] Determine whether the sunshade needs to be adjusted based on the sunlight intensity information. If so,

[0125] Obtain vehicle driving information;

[0126] Determine whether the front sunshade needs to be adjusted and / or determine whether the side sunshade needs to be adjusted according to the vehicle driving information, and if so,

[0127] Get the driver's sight height;

[0128] generating an adjustment signal according to the driver's sight height and vehicle driving information;

[0129] The adjustment signal is sent to the sunshade control device in the direction that needs to be adjusted, so that the sunshade control device adjusts the length of the sunshade in the direction that needs to be adjusted according to the adjustment signal.

[0130] In another embodiment, after sending the adjustment signal to the sunshade control device in the direction to be adjusted so that the sunshade control device adjusts the length of the sunshade in the direction to be adjusted according to the adjustment signal, the bus sunshade control method further includes:

[0131] Generate consulting voice;

[0132] Obtain the driver's answer voice according to the consultation voice feedback;

[0133] Recognize the answering voice and determine whether the driver agrees with the current length of the sunshade. If not,

[0134] Generate and adjust inquiry voice;

[0135] Acquiring an adjustment feedback voice of the driver according to the adjustment inquiry voice feedback;

[0136] Recognize adjustment feedback speech to obtain adjustment semantics;

[0137] generating a sunshade fine-tuning signal according to the adjustment semantics;

[0138] The sunshade curtain fine-tuning signal is sent to the sunshade curtain control device in the direction that needs to be adjusted, so that the sunshade curtain control device adjusts the length of the sunshade curtain in the direction that needs to be adjusted according to the sunshade curtain fine-tuning signal.

[0139] When the sunshade is adjusted automatically, it is very likely that the situation after adjustment is not satisfactory to the driver. For example, the driver wears sunglasses, is not afraid of the sun in front, and hopes to bask in the sun. At this time, the driver's needs can be known through voice interaction. For example, when the sunshade is lowered, the driver asks to raise the sunshade, then adjustments will be made according to the driver's requirements.

[0140] In this embodiment, generating a sunshade fine-tuning signal according to the adjustment semantics includes:

[0141] Determine whether there is adjustment direction information in the adjustment semantics. If so,

[0142] Determine whether there is adjustment distance information in the adjustment voice. If so,

[0143] A sunshade fine-tuning signal is generated according to the adjustment direction information and the adjustment distance information.

[0144] In the case of semantic recognition, if it is recognized that the driver wants to adjust the specific direction and displacement, the adjustment is made according to the driver's request. For example, if the driver says, adjust it down 2 centimeters, then the adjustment is made according to the driver's request.

[0145] If the driver only says the adjustment direction, the adjustment is performed according to the adjustment direction at the preset distance.

[0146] The present application also provides a bus sunshade control device, which includes a sunlight intensity information acquisition module, a sunshade adjustment judgment module, a vehicle driving information acquisition module, a sunshade adjustment selection module, a line of sight height acquisition module, an adjustment signal generation module and a sending module, wherein the sunlight intensity information acquisition module is used to acquire sunlight intensity information; the sunshade adjustment judgment module is used to judge whether the sunshade needs to be adjusted according to the sunlight intensity information; the vehicle driving information acquisition module is used to acquire vehicle driving information when the sunshade adjustment judgment module judges to be yes; the sunshade adjustment selection module is used to acquire the sunshade that needs to be adjusted according to the vehicle driving information; the line of sight height acquisition module is used to acquire the driver's line of sight height; the adjustment signal generation module is used to generate an adjustment signal according to the driver's line of sight height and the vehicle driving information; the sending module is used to send the adjustment signal to the sunshade control device in the direction that needs to be adjusted, so that the sunshade control device adjusts the length of the sunshade in the direction that needs to be adjusted according to the adjustment signal.

[0148] The bus sunshade control device is the bus sunshade control device as described above, and the bus sunshade control device adopts the bus sunshade control method as described above to obtain an adjustment signal, and transmits the adjustment signal to the front direction sunshade control device in the front direction sunshade assembly and / or the sunshade control device in the side direction sunshade assembly.

[0149] In this embodiment, the driver's sight height is acquired through a camera device.
