Detailed Description
The technical problem to be solved by the invention is as follows: the existing evaluation method for the driving behavior of the driver can generate errors when accidents happen to the road, so that the driving behavior of the driver cannot be reasonably standardized. The technical idea of the invention for solving the technical problem is as follows: qualitatively analyzing the road condition of the road where the vehicle is located, and determining the driving behavior of a driver according to the current running condition of the vehicle; and evaluating the driving behavior of the driver according to the driving behavior standard template corresponding to the road condition, so as to standardize the driving behavior of the driver.
In order to make the technical purpose, technical solutions and technical effects of the present invention more clear and facilitate those skilled in the art to understand and implement the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, fig. 1 shows a flowchart of a method for normalizing driver driving behavior according to an embodiment of the present invention, which includes the steps of:
in this step, the road condition information may include road speed limit information, vehicle front obstacle information, traffic signal light information, and road surface problem information. Here, the obstacle information in front of the vehicle may be composed of congestion sub-information and traffic accident sub-information of the road where the vehicle is located; when the road where the vehicle is located is congested, the vehicle can not move forward completely; and when a car accident occurs in front of the vehicle, the vehicle may move forward by changing lanes. It is understood that, herein, a car accident refers to only a general car accident; the series of car accidents occurring in multiple lanes are summarized in the road congestion sub-information where the vehicles are located. The road surface problem information includes road surface icing information, road surface fogging information, and road surface land subsidence information. When the road surface is frozen or fogged, the vehicle must walk slowly. When the road surface is sunk, the vehicle needs to change the road. It can be seen that the driving behavior of the driver is different under different road condition information. According to the driving behavior standardization module database, different driving behavior standardization templates are formulated according to different road condition information, and various driving behavior standardization templates are integrated to form the driving behavior standardization module database. Here, the driving behavior specification template includes a velocity behavior, an acceleration behavior, and a turning behavior; here, the acceleration behavior includes acceleration behavior, deceleration behavior, and sudden stop behavior. For example, when the road where the vehicle is located is congested, the driving behavior specification template corresponding to the current road condition information is a deceleration behavior or an emergency stop behavior; when the traffic signal lamp is a green light and a traffic accident occurs in front of the vehicle, the driving behavior specification template corresponding to the current road condition information is a turning behavior; when the road is fogged and the traffic signal lamp is green, the driving behavior standard template corresponding to the current road condition information is the speed behavior of lower-speed driving.
The current running condition of the vehicle includes a vehicle speed condition and an acceleration condition, where the acceleration in the acceleration condition is a vector. The method for acquiring the current road condition information of the road where the vehicle is located can adopt a detection method of a sensor of the vehicle or a communication acquisition method with a vehicle networking center, or a combination method of the two methods.
in this step, the determination of the current driving behavior of the driver can be made according to the actual factors of the vehicle, and some relevant judgment reference standards are made, including: acceleration threshold, angular velocity threshold, etc. For example, when the acceleration value at a certain moment or time exceeds the established acceleration threshold, it indicates that the driver has acceleration behavior or sudden stop behavior; when the acceleration value of a certain moment or a certain period of time exceeds the established angular speed threshold value, the turning behavior of the driver is indicated.
In the step, when the current driving behavior of the driver is inconsistent with the current driving behavior standard template, evaluating that the current driving behavior of the driver is not standard; and when the current driving behavior of the driver is consistent with the current driving behavior standard template, evaluating that the current driving behavior of the driver is standard.
Further, the embodiment mainly aims at making driving behavior reminding aiming at the non-standard driving behavior of the driver. Here, the driving behavior reminding mode may be a voice reminding mode and/or a reminding mode of an image and/or a character on the vehicle-mounted terminal.
Further, in this embodiment, step 300 further includes:
calculating to obtain a driving behavior reminding rate according to the ratio of the driving behavior reminding times to the driving behavior standard template variation times; the driving behavior reminding times are the times for reminding the driver of the driving behavior, and the driving behavior standard template changing times are the times for changing the driving behavior standard template;
the driver is then informed of the driving behavior alert rate.
It can be understood that, in the above steps, when the method for standardizing the driving behavior of the driver is not used, the number of times of the change of the driving behavior standard template is zero; the driving behavior specification template changes with the change of the road condition information.
Further, in the above steps, step 300 further includes:
in the case of performing the driving behavior alert, if the driver executes the driving behavior specified by the driving behavior specification template at that time before the number of times of the driving behavior specification template change, the improved driving behavior alert ratio is corrected.
In the invention, the driving level of the driver can be effectively evaluated by calculating the driving behavior reminding rate, and law enforcement personnel can correspondingly enforce the law according to the evaluation result, and meanwhile, the driver can also determine whether to need to learn again according to the evaluation result so as to improve the driving capability.
Further, as shown in fig. 2, fig. 2 is a functional module diagram of the device for normalizing driver's driving behavior according to the embodiment of the present invention. The invention also provides a device for correspondingly standardizing the driving behaviors of the driver based on the method for standardizing the driving behaviors of the driver, which comprises the following steps:

the road condition information may include road speed limit information, vehicle front obstacle information, traffic signal light information, and road surface problem information. Here, the obstacle information in front of the vehicle may be composed of congestion sub-information and traffic accident sub-information of the road where the vehicle is located; when the road where the vehicle is located is congested, the vehicle can not move forward completely; and when a car accident occurs in front of the vehicle, the vehicle may move forward by changing lanes. It is understood that, herein, a car accident refers to only a general car accident; the series of car accidents occurring in multiple lanes are summarized in the road congestion sub-information where the vehicles are located. The road surface problem information includes road surface icing information, road surface fogging information, and road surface land subsidence information. When the road surface is frozen or fogged, the vehicle must walk slowly. When the road surface is sunk, the vehicle needs to change the road. It can be seen that the driving behavior of the driver is different under different road condition information. According to the driving behavior standardization module database, different driving behavior standardization templates are formulated according to different road condition information, and various driving behavior standardization templates are integrated to form the driving behavior standardization module database. Here, the driving behavior specification template includes a velocity behavior, an acceleration behavior, and a turning behavior; here, the acceleration behavior includes acceleration behavior, deceleration behavior, and sudden stop behavior. For example, when the road where the vehicle is located is congested, the driving behavior specification template corresponding to the current road condition information is a deceleration behavior or an emergency stop behavior; when the traffic signal lamp is a green light and a traffic accident occurs in front of the vehicle, the driving behavior specification template corresponding to the current road condition information is a turning behavior; when the road is fogged and the traffic signal lamp is green, the driving behavior standard template corresponding to the current road condition information is the speed behavior of lower-speed driving.
The current running condition of the vehicle includes a vehicle speed condition and an acceleration condition, where the acceleration in the acceleration condition is a vector. The method for acquiring the current road condition information of the road where the vehicle is located can adopt a detection method of a sensor of the vehicle or a communication acquisition method with a vehicle networking center, or a combination method of the two methods.

Further, the embodiment mainly aims at making driving behavior reminding aiming at the non-standard driving behavior of the driver. Here, the driving behavior reminding mode may be a voice reminding mode and/or a reminding mode of an image and/or a character on the vehicle-mounted terminal.
