Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the present invention provides a system for prompting that a rear wiper is not closed, which comprises a front wiper switch, a rear wiper switch, a vehicle body control module, a meter, a streaming media rearview mirror and a streaming media rearview mirror lens. The front windscreen wiper switch, the rear windscreen wiper switch, the streaming media rearview mirror and the instrument are all connected with the vehicle body control module. The streaming media rearview mirror lens shoots the environment behind the vehicle and sends the shot image to the streaming media rearview mirror in real time so as to present the environment behind the vehicle.
When the automobile body control module judges the action of the rear windscreen wiper, the state of a front windscreen wiper switch is detected, and whether the rear windscreen wiper is closed or not is determined according to the closing condition of the front windscreen wiper switch. If the vehicle body control module detects that the front wiper switch is closed, the action of the rear wiper is continuously monitored; and if the rear windscreen wiper acts and the front windscreen wiper switch is not closed, prompting a driver to close the rear windscreen wiper.
The vehicle body control module can prompt a driver to close the rear windscreen wiper in a graphic flashing or text mode on the streaming media rearview mirror; and a prompting signal CAN be sent to the instrument through the CAN bus by the flow media rearview mirror, so that a driver is prompted to close the rear windscreen wiper on the instrument.
As shown in fig. 2, based on the above system, the present invention provides a method for prompting that a rear wiper is not closed, which comprises the following steps:
after the system finishes initialization, a stream media rearview mirror lens is started to shoot an environment behind a vehicle, the position of a windscreen wiper ON a rear windshield is monitored through the stream media rearview mirror lens, a vehicle body control module compares three continuous frames of images (one frame is transmitted by an image 40 ms) collected by the lens, and if the positions of the windscreen wiper in the three continuous frames of images are different, the rear windscreen wiper is judged to be in motion at the moment; and if the positions of the rear windscreen wipers are the same in the three continuous frames of images, judging that the rear windscreen wipers do not act.
When the rear windscreen wiper does not act, determining whether a rear windscreen wiper switch is closed, and if the rear windscreen wiper switch is in an open state, continuing to detect; if the windshield wiper is in a closed state, judging that the rear windshield wiper has a fault (the rear windshield wiper should act but does not act), diagnosing the fault and reporting the fault through an instrument;
and when the rear windscreen wiper is judged to have action, determining whether the front windscreen wiper switch is closed or whether the front windscreen wiper acts. If the front wiper switch is in a closed state or the front wiper acts, continuing to detect; if the front windscreen wiper switch is in a disconnected state or the front windscreen wiper does not act, the rear windscreen wiper is considered to be triggered mistakenly at the moment, a driver is prompted to close the rear windscreen wiper through figure flicker or characters on the streaming media rearview mirror, or a prompting signal is sent to an instrument through a CAN (controller area network) bus through the streaming media rearview mirror, and the driver is prompted to close the rear windscreen wiper on the instrument.
If the front wiper switch is in a closed state, whether the front wiper operates can be continuously monitored, if the front wiper does not operate, the front wiper is judged to have a fault (the front wiper should operate but does not operate), fault diagnosis is carried out, and the fault is reported through an instrument.
Alternatively, it may be determined whether the front/rear wiper is operated by:
1) the vehicle body control module detects whether the front/rear windscreen wiper operates or not by monitoring the current for driving the front/rear windscreen wiper output channel. If the front/rear wiper output channel has current and the current magnitude exceeds a certain threshold value, the current front/rear wiper is judged to be acting.
2) Whether the front/rear wiper is currently operated or not is determined by adding a pressure sensor to the front/rear wiper brushing area on the front/rear windshield (but this scheme has the possibility of misjudgment).
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Those not described in detail in this specification are within the skill of the art.
