EXAMPLE six
Fig. 6 is a flowchart illustrating a method for determining fatigue driving according to the present invention, which includes:
step S601, receiving timing information sent by a vehicle;
step S602, if the difference value between the timestamp of the currently received timing information and the timestamp of the timing information received last time is smaller than a rest threshold value, and the difference value between the timestamp of the currently received timing information and the initial timestamp is greater than or equal to a driving time threshold value, the fatigue judgment result is fatigue driving;
step S603, returning the fatigue determination result to the vehicle.
Specifically, the present embodiment is applied to a server. The vehicle sends timing information at regular time, step S601 is triggered when the server receives the timing information, then step S602 is executed, and whether fatigue driving is achieved is judged according to the timestamp difference value of the received timing information, the rest threshold value and the driving duration threshold value.
If the difference between the timestamp of the currently received timing information and the timestamp of the timing information received last time is less than the rest threshold, it indicates that the driver has not had a rest during the period. Therefore, if the difference between the timestamp of the currently received timing information and the initial timestamp is judged to be greater than or equal to the driving time threshold, fatigue driving can be judged. Wherein the initial timestamp is a timestamp of the first timing information sent when the vehicle started. If the difference value between the timestamp of the currently received timing information and the timestamp of the timing information received last time is larger than or equal to the rest threshold value, the driver is indicated to have a rest in the period, and therefore fatigue driving does not need to be judged.
The present embodiment calculates the driving time and the rest time according to the time stamp of the timing information transmitted by the vehicle, thereby achieving the function of fatigue driving recognition. The scheme does not need expensive sensors and has good cost advantage.
EXAMPLE seven
Fig. 7 is a flowchart illustrating a fatigue driving determination method according to a seventh embodiment of the present invention, including:
step S701, receiving timing information sent by a vehicle;
step S702, if the difference value between the timestamp of the currently received timing information and the timestamp of the timing information received last time is greater than or equal to the adjustable rest threshold value, and the difference value between the timestamp of the currently received timing information and the initial timestamp is less than the adjustable driving time threshold value, the fatigue judgment result is non-fatigue driving, the timestamp of the currently received timing information is taken as the initial timestamp, and step S705 is executed, otherwise step S703 is executed;
step S703, if the difference between the timestamp of the currently received timing information and the timestamp of the timing information received last time is smaller than the legal rest threshold, and the difference between the timestamp of the currently received timing information and the initial timestamp is greater than or equal to the legal driving duration threshold, the fatigue determination result is fatigue driving, and step S705 is executed; otherwise, executing step S704;
step S704, judging that the fatigue driving is not the fatigue driving, wherein the adjustable rest threshold is less than or equal to the legal rest threshold, the adjustable driving time threshold is less than or equal to the legal driving time threshold, and the adjustable rest threshold is set according to the residual driving timestamp of the vehicle and/or the adjustable driving time threshold and is set according to the adjustable rest threshold;
step S705 returns the fatigue determination result to the vehicle.
Specifically, when the driver has taken a short break, the initial timestamp may be reset and the count may be re-incremented. The rest threshold value is divided into an adjustable rest threshold value and a legal rest threshold value, and the driving time threshold value is divided into an adjustable driving time threshold value and a legal driving time threshold value. The adjustable rest threshold and the adjustable driving time threshold are both dynamically adjustable. The legal rest threshold and the legal driving time threshold are not adjustable, and the rest time is preferably 3 minutes after 4 hours of driving specified by traffic regulations. The adjustable rest threshold and the adjustable driving time threshold are in a dynamic relation, preferably a linear dynamic relation, namely the larger the adjustable rest threshold is, the larger the adjustable driving time threshold is, so that the longer short rest time can correspond to the longer continuous driving time, and the individual difference of different drivers is adapted.
The embodiment adapts to individual differences of different drivers by setting the adjustable rest threshold and the adjustable driving time threshold.
In one embodiment, the method further comprises the following steps: and if the time stamp of the currently received timing information is not continuous with the time stamp of the timing information received last time, taking the time stamp of the currently received timing information as the initial time stamp.
As shown in fig. 8, the embodiment considers the trigger logic of the network abnormal scenario, and avoids the false trigger of the network abnormal scenario.
The first scene is a scene in which the vehicle runs after the network is disconnected in the normal uploading and running process of data (timing information), after the driving time threshold is exceeded, the network is disconnected so that reminding cannot be triggered, the data is retransmitted and then retransmitted, the time stamps of the data are continuous at the moment and can be judged to be normal data, and the calculation and the judgment are carried out according to the time of the data, the driving time threshold and the rest threshold.
Wherein, the second, third and fourth scenes are normal uploading of data during driving, and no data is uploaded after flameout. And restarting the normal uploading of the data after driving. At this time, the data time stamp is found to be discontinuous and is recalculated, so that the requirement of recalculation after flameout and rest is met.

step S902, if the uploading data time and the system time of the timing information are less than or equal to a minutes, recording a starting timestamp t1, executing step S903, otherwise, executing step S902 again;
step S903, if t (n) -t (n-1) is not less than the first adjustable rest threshold value, and t (n) -t (1) < the first driving time threshold value, executing step S904, otherwise executing step S905;
step S904, the client has taken a rest, counts again, and executes step S902;
step S905, continue counting;

step S907, the client takes a rest, counts again and executes step S902;
step S908, continue counting;
step S909, if t (n) -t (n-1) < legal rest threshold value and t (n) -t (1) ≧ legal driving duration threshold value, triggering fatigue driving reminding, otherwise executing step S910;
in step S910, the client takes a rest, counts again, and executes step S902.
The starting counting and the ending counting of the running time are set to be the time difference between the required data uploading time and the system time being less than or equal to a minutes, and the risk caused by network uncontrollable is avoided. The adjustable rest threshold and the adjustable driving duration threshold are linearly changed. t (n) refers to the timestamp of the n-th frame timing information received in the background, and t (n) -t (n-1) refers to the time difference between two consecutive frames of timing information. The background time difference refers to an absolute value of a time difference between a timestamp of the uploaded timing information and the background.
