The onboard computers 30 of the plurality of vehicles 60 are installed with clients of the vehicle driving behavior evaluation system that interact with the cloud server 40, so that users of the vehicles transmit evaluation information to the vehicle driving behavior evaluation system of the cloud server 40 through the onboard computers.
Fig. 2 shows a schematic illustration of the vehicle 60 according to an embodiment of the invention. The vehicle 60 shown in fig. 2 includes an in-vehicle computer 30, a sensing device 20 connected to the in-vehicle computer 30, and a communication device 50 for communication between the vehicle 50 and the cloud server. According to the embodiment of the present invention, the sensing device 20 is a plurality of vehicle-mounted camera apparatuses, and may include, but is not limited to, a front view camera, a left view camera, a right view camera, a rear view camera, and the like of a vehicle. According to the method and the device for evaluating the driving behavior of the vehicle, provided by the embodiment of the invention, the method and the device based on the incentive mechanism are established, so that the good driving habits of a driver can be developed, the traffic jam is relieved, and the traffic accidents are avoided.
According to the embodiment of the present invention, the cloud server 40 is configured to manage account numbers of terminal devices, such as the vehicle 50, or mobile devices, such as mobile phones, and complete incentive measures such as rewarding. The mobile device is connected with the vehicle-mounted computer 30 of the vehicle 50 in a wired or wireless manner, so that the other vehicles are evaluated by using the identity of the vehicle, and at the moment, the mobile device is provided with a client of a vehicle driving behavior evaluation system for performing information interaction with the cloud server 40.

According to the embodiment of the present invention, each terminal device, such as a vehicle or a mobile device, has a fixed account on the cloud platform, and can communicate with the cloud platform server 40 through the communication module. As shown in fig. 3, a schematic diagram of an application scenario for evaluating vehicle driving behavior according to an embodiment of the present invention is shown. According to the embodiment of the invention, in a road driving scene, the vehicle-mounted computer 30 acquires the identity information of other vehicles having an interaction process with the current vehicle; and evaluating the other vehicles by the current vehicle in a vehicle driving behavior evaluation system according to the driving behaviors of the other vehicles in the interaction process. The road driving scenes comprise scenes that the vehicles are driven in the same direction and are located in different lanes or the same lane, scenes that the vehicles are driven in opposite directions, scenes that the vehicles stop at an intersection of traffic lights and wait, and the like.
According to the embodiment of the present invention, the evaluated driving behavior is driving-friendly behavior, and the evaluation of the driving-friendly behavior of the other vehicle is to enjoy the other vehicle in the driving behavior evaluation system of the cloud server 40. Such friendly driving behaviors include courtesy behaviors of other vehicles during the merging of the current vehicle, or friendly behaviors of other vehicles to appropriately adjust the headlights during the night-time opposite-direction driving with the current vehicle, and the like. However, the present invention is not limited to this, and other vehicles may be evaluated for differences in the driving behavior evaluation system. To ensure that the evaluation in the driving behavior evaluation system is an effective evaluation in a road driving scene, the cloud server 40 may identify navigation position information of the current vehicle and other vehicles and note the navigation information in the effective evaluation to prevent false or malicious evaluation.
The road driving scenario shown in fig. 3 is an example of an embodiment of the present invention, in which there are vehicles A, B and C on two lanes, respectively, where a and C are on a first lane and B is on an adjacent second lane. As shown, the B vehicle intends to change from the second lane to the first lane, but finds the vehicle a in front and the vehicle C in the lateral rear of the first lane. The driver of the vehicle B turns on the steering lamp to prompt the driver to change the lane, and the sensing module vehicle-mounted camera 20 of the vehicle B acquires the position information and the vehicle identity information (such as the license plate number) of the vehicle C behind and beside the vehicle and transmits the information to the vehicle-mounted computer 30. The B vehicle terminal sensing module refers to a monocular camera and a millimeter wave radar or a binocular camera system. The sensing modules are installed around the body of the vehicle and can comprise a front-view camera, a left-side view camera, a right-side view camera, a rear-view camera and the like of the vehicle.
The calculation module of the vehicle-mounted computer 30 calculates whether it is necessary to give a reward evaluation to the driving behavior of the other vehicle, that is, whether the vehicle B meets the lane change condition at this time. The relevant information is sent to the cloud server 40.
FIG. 4 shows a flow diagram of a reward condition calculation method according to one embodiment of the invention. The symbols therein have the following meanings:
s: the inter-vehicle distance between the host vehicle and the rear (side-to-side) vehicle;
v: the current speed of the vehicle;
s (v): the distance between the vehicle and the rear vehicle is required for safe lane change at the current vehicle speed.
S (v) may be a table stored in the vehicle-mounted computer, and may be set in advance according to experience and measurement data, such as:
and during the running process, determining S by looking up a table according to the current vehicle speed v.
As shown in fig. 4, after the turn signal of the current vehicle is turned on, the in-vehicle computer 30 starts to acquire the vehicle distance and the vehicle speed, and calculates the difference between the acquired actual vehicle distance and the vehicle distance required for safe lane change. And if the lane change can be safely carried out, normally changing the lane and turning off a turn light. If the safe lane-changing distance is not reached, waiting for the courtesy of the vehicles at the side rear, changing the lane and watching the vehicles at the side rear until the safe lane-changing distance is reached, namely s-S (v) > 0.
Although the process of making a notice during the running of the vehicle is exemplified in the above embodiments, it will be understood by those skilled in the art that the present invention is not limited thereto. In order to achieve safe driving, the rewarding process and steps are not executed during driving, the rewarding conditions during driving are displayed to the vehicle user only in the gap of vehicle driving, such as waiting for a traffic light or after the vehicle stops driving, and whether to rewarding or not can be selected by the vehicle user.
Further, although the calculation method of the safe lane change distance, that is, re-lane change and appreciation when s-s (v) >0 is exemplified in the above embodiment, it will be understood by those skilled in the art that the present invention is not limited thereto. The in-vehicle computer 30 can display all the calculation results close to 0 to the vehicle user, and the user can decide whether to enjoy the results. The various conditions displayed to the vehicle user may include other vehicle and/or current vehicle related information such as different locations and license plate numbers for the user to select and appreciate.
Alternatively, according to the embodiment of the present invention, it is understood by those skilled in the art that the judgment of the reward condition may be made based on the experience of the vehicle user without being calculated by the in-vehicle computer.
Returning to fig. 3, the lane change condition for car B means: whether a vehicle to be lane-changed can be successfully lane-changed at the existing speed, for example, if the vehicle C does not decelerate at that time, the vehicle B can safely complete lane-change, and the following possible situations exist:
scenario 1: if the vehicle B meets the lane change condition, the early warning module of the vehicle-mounted computer 30 informs that the lane change can be carried out, namely, the vehicle B can successfully change the lane under the condition that the vehicle C does not accelerate, and the vehicle B does not enter the reward system.
Scenario 2: if the vehicle B is not in line with the lane change condition temporarily, the early warning module informs that the lane change is difficult: namely, if the vehicle C does not decelerate, the vehicle B is difficult to successfully change lanes, and then the vehicle enters the reward system.
According to the embodiment of the present invention, the reward system is installed on the cloud platform server 40, and stores the information ID of the user from the terminal vehicle or the mobile terminal, and the user information ID is associated with at least one of the license plate number of the terminal vehicle and the number of the mobile terminal, so as to facilitate the evaluation of the driving behavior of the user and the evaluation of the driving behavior of other users by the user in the reward system. For example, each reward is accumulated and recorded in the reward system in the form of points, so that the user is given corresponding rewards, including material or evaluation rewards according to the number of the points. According to the embodiment of the invention, if the lane change success of the vehicle B is due to the courtesy behavior (such as deceleration) of the vehicles at the rear and the side, the front vehicle terminal device informs the cloud platform to watch the vehicles at the rear and the side, and an incentive is given.
Optionally, if the vehicle B does not meet the lane change condition temporarily, the vehicle B terminal system transmits a signal to the cloud and waits for a signal of deceleration of the vehicle C.
Optionally, the cloud sends a signal to the designated vehicle C, and a vehicle C driver judges whether to slow down and give a way.
Optionally, if the vehicle B does not meet the lane change condition temporarily, the vehicle B mobile terminal system transmits a signal to the cloud (the signal includes the license plate information of the vehicle C of the opposite side, or other information that can be associated with the cloud account, and a request for lane giving), and the cloud sends the request to the vehicle C and waits for a signal for deceleration of the vehicle C.
Optionally, if the vehicle B does not meet the lane change condition temporarily, the vehicle B sends a lane-giving request to the designated vehicle C, and simultaneously the vehicle B directly transmits the vehicle information of the vehicle C and the lane-giving request to the cloud, and waits for a signal of deceleration of the vehicle C.
