Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a method, device, electronic equipment and storage medium for controlling a high beam of a vehicle. Background Art

[0002] When a vehicle is driving in an environment with low brightness (such as at night or in a tunnel), if the oncoming vehicle has turned on its high beam, the strong high beam from the oncoming car can easily dazzle the driver's eyes and make it impossible for the driver to judge the road conditions ahead, posing a huge hidden danger to driving safety.

[0003] In order to avoid driving safety problems caused by the abuse of high beams, the existing technology usually requires the driver to actively identify that the oncoming vehicle has turned on the high beams, and actively use the method of flashing the low beams and high beams alternately to remind the oncoming vehicle to switch to the headlights. However, due to the slow reaction of some drivers, they often fail to notice that the oncoming vehicle has turned on the high beams and take corresponding measures in time, resulting in obstructed vision and temporary blind spots when meeting close-range vehicles, which can easily cause traffic accidents. Summary of the invention

[0006] Preferably, in judging whether the oncoming vehicle has turned on the high beam based on the first ambient brightness and the second ambient brightness, if the first ambient brightness is greater than a first brightness threshold and the second ambient brightness is less than a second brightness threshold, it is determined that the oncoming vehicle has turned on the high beam.

[0007] Preferably, in judging whether the oncoming vehicle has turned on the high beam based on the first ambient brightness and the second ambient brightness, if the first ambient brightness is continuously greater than a first brightness threshold and the second ambient brightness is continuously less than a second brightness threshold during a preset first period, it is determined that the oncoming vehicle has turned on the high beam.

[0008] Preferably, the first brightness threshold is greater than the second brightness threshold.

[0009] Preferably, the preset start condition is that the perceived brightness of the vehicle's driving environment is less than a third brightness threshold.

[0023] The embodiments of the present invention provide a method and device for controlling the high beam of a vehicle based on the same concept. Since the method and the device solve problems in similar principles, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0024] Figure 1 It is a flow chart of the method for controlling the high beam of a vehicle provided by an embodiment of the present invention. This specification provides method operation steps such as the embodiment or flow chart, but more or fewer operation steps may be included based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many orders, and does not represent the only order of execution. When the actual system or server product is executed, it can be executed in the order of the method shown in the embodiment or the figure or in parallel (for example, in a parallel processor or multi-threaded processing environment).

[0025] like Figure 1 As shown, the vehicle high beam control method provided in this embodiment includes the following steps.

[0026] S101: When a preset start condition is met, the driving information of the vehicle 1 and the surrounding vehicle information are obtained.

[0027] Here, the preset start condition may be that the perceived driving environment brightness of the vehicle 1 is less than a preset third brightness threshold THC. First, the driving environment brightness of the vehicle 1 needs to be determined, which can be obtained by a sensor, or by collecting images through a vehicle-mounted camera, and then performing image processing to determine the driving environment brightness of the vehicle 1. The preset third brightness threshold THC may be set to 2lx, for example, but the present invention is not limited thereto and may also be set to other values.

[0028] When the preset start-up conditions are met, the driving information of vehicle 1 is obtained, where the driving information includes the driving speed and driving direction of vehicle 1, and the surrounding vehicle information is obtained at the same time, including the distance between the surrounding vehicles and vehicle 1 and the driving direction of the surrounding vehicles.

[0029] S102: When it is detected that the driving speed of vehicle 1 exceeds a preset speed threshold, there is an oncoming vehicle and the distance between vehicle 1 and the oncoming vehicle is less than or equal to a preset distance threshold, image information of the onboard camera of vehicle 1 is obtained.

[0030] Based on the driving speed of vehicle 1 obtained in step S101, detect whether the speed of vehicle 1 exceeds the preset speed threshold, and based on the driving direction of vehicle 1 and the driving direction of surrounding vehicles (the driving direction of the oncoming vehicle is opposite to that of vehicle 1), determine whether there is an oncoming vehicle with vehicle 1, and at the same time determine whether the distance between vehicle 1 and the oncoming vehicle is less than or equal to the preset distance threshold.

[0031] When the speed of vehicle 1 exceeds a preset speed threshold, and there is an oncoming vehicle and the distance between vehicle 1 and the oncoming vehicle is less than or equal to a preset distance threshold, image information collected by the onboard camera of vehicle 1 is obtained.

[0032] Here, the preset speed threshold may be set to 30 km / h, and the preset vehicle distance threshold may be set to 600 meters. Of course, this is only an example, and other values ​​may also be set.

[0033] S103: Determine a first ambient brightness of the oncoming vehicle and a second ambient brightness of the oncoming vehicle based on the image information, wherein the first ambient brightness refers to an ambient brightness within a preset distance range from the oncoming vehicle, and the second ambient brightness refers to an ambient brightness within a preset distance range from the oncoming vehicle.

[0034] Based on the image information including the oncoming vehicle captured by the vehicle-mounted camera of vehicle 1, and through image processing, the first ambient brightness and the second ambient brightness of the oncoming vehicle can be determined, wherein the first ambient brightness refers to the ambient brightness within a preset distance range from the oncoming vehicle, and the second ambient brightness refers to the ambient brightness within a preset distance range from the oncoming vehicle. The preset distance range here can be set based on the search distance of the high beam, and is usually set to a value in the range of 80-120 meters. In addition, the distance range from the oncoming vehicle here refers to the distance from the front part of the oncoming vehicle.

[0035] S104: Determine whether the oncoming vehicle has turned on its high beam based on the first environment brightness and the second environment brightness.

[0036] Specifically, if the first environment brightness is greater than the first brightness threshold THA and the second environment brightness is less than the second brightness threshold THB, it is determined that the oncoming vehicle has turned on the high beam. The first brightness threshold THA is greater than the second brightness threshold THB.

[0037] For example, the first brightness threshold THA may be set to 4lx, and the second brightness threshold THB may be set to 2lx, that is, the third brightness threshold may be equal to the second brightness threshold.

[0038] In addition, it is also possible to determine whether the first ambient brightness is continuously greater than the first brightness threshold and the second ambient brightness is continuously less than the second brightness threshold during the preset first period. If the first ambient brightness is continuously greater than the first brightness threshold and the second ambient brightness is continuously less than the second brightness threshold during the preset first period, it is determined that the high beam of the oncoming vehicle has been turned on.

[0039] S105: If the oncoming vehicle has turned on its high beam, prompt the oncoming vehicle to turn off its high beam.

[0040] Specifically, the low beam and high beam can be controlled to flash alternately during the preset second period, thereby prompting the oncoming vehicle to switch the headlights and turn off the high beam. A request message can also be sent to the oncoming vehicle through vehicle-to-everything (V2X) communication, prompting the oncoming vehicle to switch the headlights and turn off the high beam.

[0043] Among them, the first acquisition module 201 is used to obtain the driving information of the vehicle 1 and the surrounding vehicle information when the preset start condition is met. The second acquisition module 202 is used to obtain the image information of the vehicle-mounted camera of the vehicle 1 when it is detected that the speed of the vehicle 1 exceeds the preset speed threshold, and there is an oncoming vehicle of the vehicle 1 and the distance between the vehicle 1 and the oncoming vehicle is less than or equal to the preset distance threshold. The determination module 203 is used to determine the first ambient brightness of the oncoming vehicle and the second ambient brightness of the oncoming vehicle according to the image information, wherein the first ambient brightness refers to the ambient brightness within a preset distance range from the oncoming vehicle, and the second ambient brightness refers to the ambient brightness within a preset distance range from the oncoming vehicle. The judgment module 204 is used to determine whether the oncoming vehicle has turned on the high beam based on the first ambient brightness and the second ambient brightness. The prompt module 205 is used to prompt the oncoming vehicle to turn off the high beam when the oncoming vehicle has turned on the high beam.
