Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Referring to fig. 1, an automatic window closing system according to an embodiment includes an external sensing system, a vehicle body control system, a window lift motor, window glass, and an anti-pinch system; the glass lifting motor is connected with the window glass in a driving mode, and the vehicle body control system is connected with the external sensing system, the anti-pinch system and the glass lifting motor in a signal mode respectively. The method comprises the steps that firstly, an external sensing system collects whether water is accumulated on a road surface or not and whether external road condition information that vehicles pass through is available or not at the periphery, then a vehicle body control system judges whether the vehicle window glass needs to be closed or not according to the collected external road condition information, if the vehicle window glass needs to be closed, driving current or driving signals are output to a glass lifting motor, then the glass lifting motor controls the vehicle window glass to lift to the top, in the process that the glass lifts, the anti-pinch system senses whether foreign matter interference exists or not, and if the foreign matter interference exists, the vehicle window glass stops lifting. The automatic opening and closing function of the vehicle window is achieved in the driving process of the vehicle, so that a driver can drive the vehicle with concentration, and the safety is improved.
The external perception system comprises a video acquisition device and a radar system, wherein the video acquisition device is responsible for the acquisition and transmission work of road state information (video images), and the radar system is responsible for the acquisition and transmission work of peripheral vehicle information.
Referring to fig. 2, in the method for automatically closing a window based on the above-mentioned system, a vehicle with the system is prepared, and the vehicle is in a normal driving process. Firstly, the video acquisition device sends the acquired external road surface state information (video images) to a vehicle body control system. And secondly, the radar system sends the collected information of the surrounding vehicles to a vehicle body control system. And thirdly, the vehicle body control system judges whether the current vehicle is or is about to be in the states of water accumulation, whether vehicles run around the vehicle and the like according to the received information sent by the video acquisition device and the radar system. And fourthly, if the vehicle body control system judges that the current vehicle is or is about to be in the water accumulation road section and vehicles are around, the vehicle body control system outputs driving current or driving signals to the glass lifting motor. And if the vehicle body control system judges that the current vehicle is not in or is not about to be in the water accumulation road section or no vehicle runs around, the vehicle body control system does not output the driving current or the driving signal to the glass lifting motor. After the glass lifting motor receives the driving current or the driving signal output by the vehicle body control system, the glass lifting motor operates to move the window glass to the top position. And seventhly, in the process of lifting the window glass, the anti-clamping system collects information about whether foreign matters are clamped or the glass is blocked to lift in the whole process and sends the information to the vehicle body control system. And the body control system judges according to the received information sent by the anti-pinch system. And ninthly, outputting the corresponding driving current or driving signal to the glass lifting motor by the vehicle body control system according to the judgment result (ascending or descending). The glass lift motor moves the window glass in the r direction in response to the drive current or signal.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
