step three, judging that the camera is lifted up due to the application of the application terminal, and recording the scene in use of the current camera, wherein in the three steps, corresponding reminding is sent out while the scene in use of the current camera is recorded, for example, the user is reminded of the scene in use of the camera; the control module executes camera retracting operation when receiving a request that the driver secondary confirmation signal is to retract the camera, and keeps the current state of the camera when receiving the request that the driver secondary confirmation signal is not to retract the camera;
when the control module receives a request for using the camera, judging whether the current state of the camera is a recovery state; when the camera is judged to be in the retraction state, executing the lifting operation of the camera and monitoring the use condition of the camera, and executing the retraction operation of the camera when the use is finished; when the camera is judged to be in the lift-out state, the current scene applied by the camera is judged and a prompt is sent out, the control module controls whether the camera is switched to the current requested scene according to the secondary confirmation signal of the driver, and the specific operation comprises the following steps: when the control module receives a signal that a secondary confirmation signal of a driver is a switching agreement signal, the control module controls the camera to switch to the current requested scene and monitors the state of the current scene, and a safe driving judgment step is carried out when the camera is used completely; when receiving a signal that a secondary confirmation signal of a driver is not approved to be switched, the control module keeps and records the current state of the camera; wherein, safe driving judges the step to include:
judging whether the current driving state is in a dangerous driving scene or not, and executing camera retracting operation and recording the state when judging that the current driving state is not in the dangerous driving scene; and when the camera is judged to be in a dangerous driving scene, recording the scene currently used and sending out a corresponding prompt, and the control module reenters the operation of controlling whether the camera is switched to the scene requested currently or not according to the secondary confirmation signal of the driver.
Preferably, in the first step, the determining of the dangerous driving scene includes: whether the single-time driving time of a driver exceeds a set time, whether the transverse acceleration of the vehicle exceeds a set speed and whether the vehicle is positioned in an unmanned area or not are judged, and when any one of the conditions is met, the vehicle is judged to be in a dangerous driving scene currently. If the single driving time of the driver exceeds the set time, the state of the driver can be in a fatigue state, the driver can be monitored by using the camera when the driving request is made, the driving safety of the driver is ensured, when the transverse acceleration of the vehicle exceeds the set speed, the driving speed is higher, and danger is likely to occur if the state of the driver is not concentrated at the moment. The judgment conditions for the dangerous driving scene are not limited to the above three conditions.
Preferably, in the second step, the driving assistance function includes an intelligent driving assistance function that requires the operation of the camera, such as driver fatigue state monitoring, constant-speed cruising, automatic car following, intelligent piloting, automatic parking, and the like.
