Problems solved by technology

[0002] With the improvement of living standards, the number of motor vehicles is also increasing, and almost every household has a private car. People's travel tools have gradually changed from bicycles to cars. Cars have brought great convenience to people's travel. , but it also increases the occurrence of traffic accidents, especially when the vehicle is turning or changing lanes, the probability of rear-end collision or other traffic conditions is very high
[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in real life: many drivers have irregular driving behaviors, and these drivers did not observe the situation of the rear vehicles through the rearview mirror in time when turning or changing lanes. Even if the turn signals are not turned on in time, the vehicles behind will not understand the turning or lane changing information of the vehicles in front, resulting in traffic accidents such as rear-end collisions

Embodiment 1

[0053] figure 1 It is a flow chart of a turn prompting method provided in Embodiment 1 of the present invention, and the method can be executed by a turn prompt device. The device can be realized by means of hardware and / or software. And generally integrated in the motor vehicle driving system, the method specifically includes the following steps:

[0054] Step 110, when it is known that the driver has a turning intention, detect the three-dimensional space angle of the driver's line of sight in real time based on face recognition technology.

[0055] Among them, whether the driver has steering intention can be known according to the angle of the steering wheel of the vehicle. Typically, the angle of the steering wheel can be set to 0 when the steering wheel is in the middle position, the angle is negative when the steering wheel is turned left, and the angle is positive when the steering wheel is turned right. When the angle of the steering wheel is When the absolute value ...

Embodiment 2

[0067] Figure 4 It is a schematic flow diagram of a steering prompt method provided by Embodiment 2 of the present invention. On the basis of Embodiment 1, this embodiment has been further optimized. The advantage of optimization is that it can improve the ability to judge whether the driver has watched the rearview mirror. Accuracy, to reduce the probability of error prompts, see for details Figure 4 As shown, the method specifically includes the following steps:

[0068] Step 210, when it is known that the driver has a turning intention, detect the three-dimensional space angle of the driver's line of sight in real time based on face recognition technology.

[0069] Step 220 , judging whether the angle is within a preset range, if not, execute step 230 .

[0070] Step 230, start timing, execute step 240 to judge whether the angle is within the preset range, if so, execute step 250 to stop timing, otherwise continue to execute step 230 to continue timing.

[0071] Step 2...

Embodiment 3

[0078] Figure 5 A schematic flow chart of a steering prompt method provided by Embodiment 3 of the present invention. On the basis of the above embodiments, this embodiment optimizes how to judge the driver's steering intention. The benefit of optimization is that it can improve the judgment of whether the driver There is accuracy in steering intent. For details, see Figure 5 As shown, the method specifically includes the following steps:

[0079] Step 310, detecting the current driving speed of the vehicle.

[0080] There are many ways to detect the current driving speed of the vehicle, for example, it can be detected by a speed sensor or an acceleration sensor, and the current driving speed of the vehicle can be collected in real time through the vehicle bus. The speed setting value can be set according to the actual situation of the vehicle, for example, it can be 5km / h or 10km / h. Because when the vehicle speed reaches a certain value, the current steering angle of th...

Abstract

The invention discloses a steering prompting method and device and belongs to the technical field of vehicle steering prompting. The method comprises the steps as follows: detecting the sight three-dimensional space angle of a driver in real time based on a face recognition technology when the steering intention of the driver is obtained; judging whether the angle is within a preset range, and starting a rearview mirror watching promoting system to prompt the driver to watch a rearview mirror if the angle is not within the preset range. The sight three-dimensional space angle of the driver is detected in real time based on the face recognition technology, whether the angle is within the preset range is judged, the rearview mirror watching promoting system is started to prompt the driver to watch the rearview mirror if the angle is not within the preset range, when the steering or lane changing intention of the driver is obtained, whether the driver watches the rearview mirror and knows about the information of the road behind are monitored in real time, the driver is intelligently prompted to watch the rearview mirror if the fact that the driver does not watch the rearview mirror is discovered, and accordingly, the driving safety is improved, and the user experience is improved at the same time.
