[0002] At present, in order to prevent the driver from driving while fatigued, the prior art has begun to prevent the driver from driving the vehicle for a long time by recording the continuous driving time of the vehicle and issuing an alarm when the continuous driving time is too long.

[0003] However, the above method has certain control loopholes. For example, after driving for a period of time, the driver can turn off the vehicle engine and restart the engine to clear the recorded time, thereby eliminating the alarm. Therefore, the above method cannot reflect the driver's real state and cannot have the effect of reminding the driver. Summary of the invention

[0017] The embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0018] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. In addition, in the description of the embodiments of the present invention, unless otherwise specified, the meaning of "multiple" refers to two or more.

[0019] First, the inventive principle of the present invention is introduced: In the prior art, in order to avoid the problem of the driver driving continuously for too long, a common method is to record the working time of the vehicle engine, the continuous driving time of the vehicle, or the continuous sitting time of the driver in the cab, and when the above time is too long, an alarm is issued to remind the driver to take a rest. On the basis of the above prior art, the present invention takes into account that only recording the continuous driving time of the driver cannot reflect the real state of the driver. Therefore, the present invention records the driver's cumulative driving time and cumulative non-driving time at the same time, and judges the timing of issuing the alarm signal according to the above two time results recorded, so as to achieve a more effective and more in line with the needs of use continuous driving timeout reminder function.

[0020] Based on the above invention concept and principle, the embodiment of the present invention provides a continuous driving timeout reminder device, such as Figure 1 As shown, the continuous driving timeout reminder device 10 includes: a recording unit 101, a judgment unit 102, an alarm unit 103 and a threshold calculation unit 104.

[0021] Specifically, Figure 2 As shown, the continuous driving timeout reminder device 10 is specifically used to execute the following continuous driving timeout reminder method, which specifically includes:

[0022] S201. Record the cumulative driving time and the cumulative non-driving time of the same driver when driving the vehicle.

[0023] Specifically, in the continuous driving timeout reminder device 10, the recording unit 101 is used to record the cumulative driving time and the cumulative non-driving time when the same driver drives the vehicle.

[0024] In one implementation, step S201 specifically includes:

[0025] S2011. Acquire an image of the vehicle cab according to a preset period.

[0026] Specifically, Figure 3As shown, the recording unit 101 includes: an acquisition subunit 1011, a driver judgment subunit 1012, a driving state judgment subunit 1013 and a time recording subunit 1014.

[0027] The acquisition subunit 1011 is used to acquire the image of the vehicle cab according to a preset period.

[0028] The duration of the scheduled period can be set according to actual needs.

[0029] S2012. Based on the acquired image of the vehicle cab, use face recognition technology to determine whether the current driver is the same person as the driver in the previous period.

[0030] Specifically, in the recording unit 101, the driver determination subunit 1012 is used to determine whether the current driver is the same person as the driver in the previous period based on the acquired image of the vehicle cab and using face recognition technology.

[0031] In one implementation, it is considered that the driver may move his body posture during driving, resulting in the situation that the driver is not included in the captured image of the vehicle cab. In this case, the embodiment of the present invention considers that when the driver cannot be identified from the image of the vehicle cab, there may be two situations: one, the driver only moves his body posture and then recovers. Two, the driver may be replaced. If the driver is replaced, it can be determined by detecting several cycles later whether the current driver is the same person as the driver in the previous cycle. Therefore, in the embodiment of the present invention, S2012 specifically includes:

[0032] When the driver is not identified in the image of the vehicle cab, it is determined that the current driver is the same person as the driver in the previous cycle.

[0033] According to the result of S2012, if it is determined that the current driver is not the same person as the driver in the previous cycle, the recorded cumulative driving time and cumulative non-driving time are cleared and the recording is restarted. If it is determined that the current driver is the same person as the driver in the previous cycle, S2013 is continued.

[0034] S2013: After determining that the current driver is the same person as the driver in the previous cycle, determine whether the current driver is in a driving state.

[0035] Specifically, in the recording unit 101, the driving state judgment subunit 1013 is used to judge whether the current driver is in a driving state after determining that the current driver is the same person as the driver in the previous cycle.

[0036] In one implementation, S2013 specifically includes: judging whether the current driver is in a driving state based on current driving information; the current driving information includes: at least one of vehicle speed information, vehicle gear information, driver behavior information and road condition information.

[0037] Specifically, the above step S2013 may include:

[0038] S2013a. Determine whether the current vehicle speed is zero based on the vehicle speed information and the vehicle gear information, and determine whether the vehicle gear is in the parking gear.

[0039] If the current vehicle is not zero or the vehicle gear is in the parking gear, it is determined that the current driver is in the driving state.

[0040] S2013b. If the current vehicle speed is zero and the vehicle gear is in the parking gear, determine whether the driver is holding the steering wheel with at least one hand and looking straight ahead based on the image of the vehicle cab.

[0041] If the driver holds the steering wheel with at least one hand and looks straight ahead, it is determined that the driver is currently in a driving state.

[0042] S2013c. If the driver does not hold the steering wheel with his hands or does not look straight ahead, the road condition information is used to determine whether the road section where the vehicle is located is congested and whether the current vehicle is waiting for a traffic light.

[0043] If the road section where the vehicle is located is in a traffic jam or the current vehicle is waiting for a traffic light, it is determined that the current driver is in a driving state. If the road section where the vehicle is located is not in a traffic jam and the current vehicle is not waiting for a traffic light, it is determined that the current driver is not in a driving state.

[0044] S2014: after determining that the current driver is in a driving state, updating the accumulated driving time; after determining that the current driver is not in a driving state, updating the accumulated non-driving time.

[0045] Specifically, in the recording unit 101, the time recording subunit 1014 is used to update the accumulated driving time after determining that the current driver is in a driving state; and to update the accumulated non-driving time after determining that the current driver is not in a driving state.

[0046] S202: Calculate a first threshold time according to the age of the driver, the speed of the driver while driving the vehicle, and the type of road on which the driver drives the vehicle.

[0047] Specifically, in the continuous driving timeout reminder device 10, the threshold calculation unit 104 is used to calculate the first threshold time according to the age of the driver, the speed of the driver when driving the vehicle, and the type of road the driver drives the vehicle through, and determine whether the accumulated driving time reaches the first threshold time.

[0048] The older the driver is, the shorter the first threshold time is; the faster the driver drives the vehicle, the shorter the first threshold time is. The driver's age can be determined by acquiring an image of the cab and analyzing the degree of facial aging of the driver using face recognition technology. Alternatively, the driver can be identified using face recognition technology, and the age of the current driver can be determined using the driver's age information saved in advance.

[0049] In addition, the length of the first threshold time may be calculated according to the length of different types of roads that the driver passes through. For example, when the driver is driving the vehicle, the longer the highway is, the shorter the first threshold time is; the longer the urban road is, the longer the first threshold time is.

[0050] It should be noted that, in actual implementation, the effect of the embodiment of the present invention can also be achieved by setting a first threshold time of a fixed duration. When the first threshold time of a fixed duration is set, the content of the above step S202 may not be performed. In this case, the threshold calculation unit 104 may not be set in the continuous driving timeout reminder device 10.

[0051] S203: When the accumulated driving time reaches the first threshold time, determine whether the accumulated non-driving time is less than the second threshold time.

[0052] S204: When it is determined that the accumulated non-driving time is less than a second threshold time, a warning signal is issued.

[0053] If the accumulated non-driving time is greater than the second threshold time, the accumulated driving time and accumulated non-driving time recorded are cleared and the recording is restarted.

[0054] For example, if the first threshold time is 4 hours and the second threshold time is 20 minutes, then when the driver's cumulative driving time reaches 4 hours and the cumulative non-driving time (i.e., rest time) is less than 20 minutes, an alarm signal is issued, otherwise the record is cleared.

[0055] In the embodiment of the present invention, the driver's driving intensity is judged by simultaneously recording the driver's cumulative driving time and cumulative non-driving time, and after determining that the driver's cumulative driving time reaches the first threshold time, judging whether the driver's cumulative non-driving time is less than the second threshold time, and then sending an alarm signal based on the judgment result to remind the driver to stop and rest. The above method adopted in the embodiment of the present invention can more accurately judge whether the driver has excessive driving intensity, thereby realizing a more effective and more user-friendly continuous driving timeout reminder function.
