The general serializer 141 is integrated in the rear-view camera 14, and the deserializer 151 is integrated in the pico projector 15.
The main function of the rearview camera 14 is to collect image data of the rear vehicle, mainly including image data of the head of the rear vehicle, and identify the collected image data of the rear vehicle through an intelligent image identification algorithm to judge whether the rear vehicle starts a high beam or not. The intelligent image recognition algorithm is a relatively mature prior art, and is not described herein again, and the related technical principle can refer to the description in the prior art.
The main function of the micro-projector 15 is to project and display an image containing an image or text information that the user wants to show to the following vehicle, such as text information of "please turn off the high beam", so as to prompt the following vehicle to turn off the high beam.
The light sensors 12 and 13, the rear-view camera 14 and the micro-projector 15 may be powered by the power supply of the vehicle-mounted multimedia controller 11, or may be powered directly by other vehicle-mounted hardware modules or vehicle-mounted power supply devices such as a vehicle-mounted battery.
The utility model discloses a main theory of operation for controlling means of car of example is: the vehicle-mounted multimedia controller 11 polls and collects data of the light sensors 12 and 13 integrated on the left and right rearview mirrors of the vehicle, and determines whether the light intensity from the rear of the vehicle exceeds a preset intensity threshold, for example, a calibration may be performed after the vehicle is off-line to obtain the preset intensity threshold, and the value range of the preset intensity threshold may be, for example, 1000LM to 1200LM (light intensity unit: lumen), and specifically, may be, for example, 1000 LM. If the intensity is higher than the preset intensity threshold value, the high beam is judged to be possibly turned on by the rear vehicle, image data collected by the rearview camera 14 is obtained at the moment, whether the high beam is really turned on by the rear vehicle is judged through an intelligent image recognition algorithm, if the high beam is really turned on by the rear vehicle, the micro projector 15 positioned above the rear windshield of the vehicle is turned on, and prompt information preset by a user is projected to the projection area 16 on the rear windshield. After the driver of the rear vehicle sees the projected prompt message, the driver realizes the improper behavior of the driver and turns off the high beam or switches to the low beam, at the moment, the light intensity received by the light sensors 12 and 13 is reduced, and when the detected light intensity is lower than the preset intensity threshold value, the micro projector 15 is turned off and the projection of the prompt message is stopped. And then continues to circularly monitor the detection data of the light sensors 12 and 13.
As shown in fig. 5, a schematic work flow diagram of the control device for an automobile according to the example of the present invention includes the following steps:
1) after the vehicle is powered on and started, the vehicle-mounted multimedia controller 11 is powered on and started to start running.
2) The vehicle multimedia controller 11 continuously cycles through reading the data from the light sensors 12, 13 and calculates whether a predetermined intensity threshold has been exceeded.
3) And if the result in the step 2) is judged that the preset intensity threshold value is not exceeded, continuing to execute the step 1). If the intensity exceeds the preset intensity threshold value, the vehicle-mounted multimedia controller 11 opens the rear-view camera 14, acquires an image which is acquired by the rear-view camera 14 and comprises the head of the rear vehicle, processes the acquired data of the rear-view camera 14 by using an intelligent image recognition algorithm, and judges whether the rear vehicle starts a high beam according to a processing result.
4) If the high beam is not turned on in 3), the vehicle-mounted multimedia controller 11 turns off the rear view camera and continues to execute step 2). If it is determined that the rear vehicle has the high beam turned on, the vehicle-mounted multimedia controller 11 turns on the micro projector 15, starts projecting the contents of the prompt to the rear windshield, and turns off the rear-view camera 14.
5) The vehicle multimedia controller 11 continues to cycle through the data from the light sensors 12, 13 to determine whether a predetermined intensity threshold has been exceeded. If the result in the step 5) is judged to still exceed the preset intensity threshold value, the vehicle-mounted multimedia controller 11 controls the micro projector 15 to continue projecting the prompting content. If the preset intensity threshold is not exceeded, the rear vehicle has turned off the high beam or the two vehicles are far away, the vehicle-mounted multimedia controller 11 turns off the micro projector 15, and then the step 2 is executed continuously.
It should be noted that in other embodiments, the data of the light sensors 12 and 13 and the data of the rear-view camera 14 may also be directly obtained continuously, whether the light intensity exceeding the preset intensity threshold and the condition of whether the high beam is turned on are determined according to the data of the light sensors and the data of the rear-view camera, if the two conditions are met, the micro projector 15 is turned on to project corresponding prompt information, and if the two conditions are not met, the micro projector is turned off to no longer project corresponding prompt information. Data can be collected only by the light sensors 12 and 13, whether the rear vehicle starts a high beam or not can be judged according to the data collected by the light sensors 12 and 13, but the method is easily interfered by occasionally-appearing strong light in the surrounding environment to cause misjudgment, particularly during daytime driving.
