In addition, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present invention. It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, well known means have not been described in detail so as not to obscure the present invention.

Referring to fig. 1, an embodiment of the present invention provides a safe driving control method, including the following steps S1-S4:

step S1, acquiring the video watching duration of the driver in a preset time period before the current time;

specifically, for example, if the current time is T, the preset time period is a time period [ T-T, T ] from the time T-T to the time T; t is a preset time length parameter value.

And step S2, determining the time length grade corresponding to the video watching time length.

Specifically, in the present embodiment, a plurality of duration levels are preset, each duration level corresponds to a video viewing duration range, for example, 1 hour to 1.5 hours is one duration range, and for example, 1.5 hours to 2 hours is another duration range, and so on, and the duration range may be specifically set according to technical requirements.

And step S3, determining the corresponding vehicle state limiting condition according to the duration grade.

Specifically, different vehicle state limiting conditions are preset corresponding to different time length levels, it should be noted that the longer the video watching time length is, the higher the time length level is, the stricter the corresponding vehicle state limiting conditions are, for example, the lower the upper limit of the vehicle speed is, for example, the larger the following distance from the front vehicle is, and the like, and this is only an example.

And step S4, detecting the vehicle state in real time during the driving process of the driver, and controlling the vehicle state to meet the vehicle state limiting condition.

Specifically, the detection of the vehicle state may be to acquire a vehicle state signal, such as a vehicle speed, a following distance from a preceding vehicle, an acceleration, and the like, through a local CAN network of the vehicle; correspondingly, the vehicle state limiting condition is a limiting condition corresponding to the acquired target vehicle state signal, namely a critical value, and can be understood as a safe driving boundary in the driving process.

According to the method, the corresponding vehicle state limiting condition is determined according to the video watching time length before the driver leaves the vehicle, the vehicle state is detected in real time in the subsequent driving process of the driver, the vehicle state is controlled to meet the vehicle state limiting condition, a necessary safety mechanism can be provided for the driver in advance before the driver leaves the vehicle, and the probability of traffic accidents caused by fatigue of the sense organ of the driver due to the video watching behavior before the driver leaves the vehicle can be reduced. In addition, the scheme does not need a driver to wear additional detection equipment, can be realized based on the existing vehicle configuration conditions, does not cause new cost in application, and has a wide application prospect.

Optionally, the method of an embodiment further comprises steps S5 and S6:

and step S5, determining the corresponding longest continuous driving time according to the duration grade.

Specifically, the longer the video viewing time is, the higher the time level is, the more fatigue the state of the driver is, the shorter the corresponding longest continuous running time should be, and according to the above principle, different longest continuous running times may be preset corresponding to different time levels.

And step S6, detecting the continuous driving time of the vehicle in real time in the driving process of the driver, and outputting prompt information for prompting the driver to rest when the continuous driving time of the vehicle reaches the maximum continuous driving time.

Specifically, the prompting method of the prompting information is preferably, but not limited to, voice prompting. The continuous running time of the vehicle can be calculated by a timer, and the timer is started when the vehicle starts running.

It should be noted that, compared to the prior art, the driver is reminded to have a rest after the set duration of continuous driving, in this embodiment, it is considered that the video watching behavior of the driver before driving may cause fatigue to brain nerves and sense organs of the driver, and the longest continuous driving time of the current driver needs to adjust the video watching duration.

Optionally, the method of an embodiment further includes step S7:

and step S7, after the prompt information for prompting the driver to rest is output, acquiring the driving state information of the driver, judging whether the driver continues to drive according to the driving state information of the driver, and if the driver continues to drive, setting the upper limit speed of the vehicle as a preset speed threshold value.

Specifically, the driving state information may be determined including accelerator pedal opening information, gear position information of the vehicle, and the like; it should be noted that the preset vehicle speed threshold value in step S7 is a preset fixed vehicle speed value, which is different from the vehicle state limiting condition described above.

Preferably, the preset fixed vehicle speed value is smaller than the vehicle speed limit value in the vehicle state limit condition.

For example, the step S1 may specifically include steps S11 to S12:

and step S11, outputting prompt information for prompting the driver to input the video watching time length when the whole vehicle is powered on.

And step S12, responding to the input operation of the user, and acquiring the video watching time length which is input by the user and is within the preset time period before the current time.

Further illustratively, the step S1 may specifically include steps S13 to S15:

and step S13, when the whole vehicle is powered on, receiving the face image of the driver shot by the vehicle-mounted camera.

Step S14, sending an inquiry request and the face image to a server; the query request is used for enabling the server to query the viewer monitoring videos uploaded by the terminal equipment in the preset time period before the current time according to the facial images, and the video watching time length of the driver in the preset time period before the current time is obtained.

Specifically, the server responds to the received query request and the face image, queries the viewer monitoring videos uploaded by a plurality of terminal devices in a preset time period [ T-T, T ], and detects the video watching time length T (watch) of the current driver in the preset time period [ T-T, T ] according to the face image and the viewer monitoring videos; and when the plurality of terminal devices are in a video playing state, transmitting the collected monitoring pictures of the viewers to the server in real time. The plurality of terminal devices may be terminal devices previously associated with the vehicle or the current driver, for example, a television and a smart phone at home of the current driver are previously associated with the vehicle, and the viewer monitoring video uploaded by the terminal device associated with the current driver is directly queried during query; of course, it is also possible to query the monitored videos from all the viewers of the terminal device having the function, which is more accurate, but the time consumption is longer, and is not limited herein.

And step S15, receiving the video watching time length of the driver in the preset time period before the current time, which is sent by the server.

It should be noted that the 2 functions of obtaining the video watching duration of the driver may be simultaneously provided, that is, the vehicle may receive the video watching duration input by the user, and may detect the video watching duration through the cloud server. The function of autonomously inputting the watching time length by the user is added, so that the more real video watching time length of the user can be obtained, for example, the current driver watches the video on the video equipment which is not associated with the cloud server, and the video watching time length can be autonomously input.

Optionally, based on the above description of the embodiment, the vehicle state limiting condition preferably includes, but is not limited to:

the vehicle speed is less than a preset vehicle speed threshold value; wherein different time length grades correspond to different vehicle speed thresholds, and a plurality of vehicle speed thresholds are preset;
