And S3, generating reminding information according to the change curve and the preset curve corresponding to the change curve. The preset curve can be calibrated according to actual conditions.
It should be noted that the prompting information described in this embodiment may be some prompting strategies corresponding to the change curve and the preset curve corresponding to the change curve, for example, if the test is an acceleration test, the acceleration curve is mainly drawn in real time, and after the acceleration is finished, a driving skill suggestion that the user reaches the optimal acceleration curve is provided according to comparison between the state information of the vehicle in the acceleration process of the user and the standard acceleration curve, for example, a certain section of acceleration is very large, and information that the steering wheel rotates is also provided, so that the passenger is prompted, and rollover is easy to occur.
In order to ensure the safety of the vehicle during the test, after the vehicle enters a corresponding test mode (for example, enters a hundred kilometers acceleration test mode), the virtual robot in the vehicle-mounted multimedia can analyze the corresponding test mode of the vehicle opening in real time to give out corresponding reminding information, and the specific analysis is as follows:
take the above test as 0-100 km acceleration test as an example. When a user controls the vehicle to enter a hundred-kilometer acceleration test mode through voice, the virtual robot can detect whether the vehicle has faults or not, and if the vehicle has the faults related to safety, the virtual robot can remind the user of not starting the acceleration test mode. If not, whether the temperature of the battery motor of the vehicle is within a reasonable range or not can be further judged, the overall power output of the vehicle is influenced by too low or too high temperature, if so, the user is reminded to advise not to start the acceleration test mode, and if not, the user is reminded to advise to preheat the vehicle firstly. Meanwhile, whether an ESP (electronic stability Program), an ABS (Anti-lock Brake System) and a front Anti-collision System are started or not can be judged, if not, a user can be reminded to start the systems for safe driving. Meanwhile, whether an air conditioner, a car light and a sound system in the car are started or not can be judged, if yes, a user can be reminded to not start for the safety of the test; and judging whether the vehicle window is opened, if so, reminding a user to close for the safety of the test.
Further, the above test is a 0-100 km acceleration test as an example. During the acceleration test of the vehicle for hundreds of kilometers, the virtual robot can detect whether the vehicle breaks down in real time, and if the vehicle breaks down, the output power of the vehicle can be limited (namely, power-limited driving); the virtual robot can detect whether the battery motor of the vehicle has temperature abnormality in real time, and if so, the output power of the vehicle can be limited. In addition, during the acceleration test of the vehicle in hundred kilometers, the ESP and the front anti-collision system can detect whether the vehicle is abnormal, if the vehicle is abnormal, the power can be cut off or the output power of the vehicle is limited, and corresponding abnormal information can be sent to inform a user of the abnormal condition: for example, the reason and the time point of the (power-limiting) abnormality can remind the user to hold the steering wheel tightly to prevent the vehicle from deviating or turning over. In addition, in the process of a hundred kilometers acceleration test of the vehicle, the virtual robot can judge whether 4 wheels of the vehicle slip or not, whether the road surface is uneven or not, whether the road surface has a slope or not, report the time point when the road surface slips, the time point when the road surface has a slope or the like according to various state data of the vehicle acquired in real time, and meanwhile, can remind a user to hold a steering wheel tightly to prevent the wheels of the vehicle from slipping or prevent the vehicle from deviating or turning over due to uneven road surface; virtual robot still can real-time detection throttle degree of depth whether at the deepest to report when the throttle is in the deepest, in order to remind the user to pay attention to safe driving.
In an embodiment of the present invention, as shown in fig. 10, the processing method of the vehicle-mounted data may further include the following steps:
and S4, analyzing the vehicle state data to obtain vehicle test result data. The test result data may include, among other things, the time, location, top speed, displacement, acceleration over hundred kilometers, deceleration over hundred kilometers, and the like.
And S5, sending the vehicle test result data and the vehicle information to a server. The vehicle information may include a vehicle type and a vehicle identification (unique identification), among others.
In the embodiment of the invention, the vehicle-mounted multimedia can also be networked to acquire the weather condition of the current test site, acquire road conditions and road surface characteristics (such as an uphill road surface, a downhill road surface, a flat bottom road surface and the like) of the current test site by combining a GPS system with a Baidu map, a Google map or a Gaode map and the like, and can send the road conditions and the road surface characteristics, the vehicle test result data and the vehicle information to the server together, so that the subsequent ranking information is more comprehensive, and the user can know the driving states of the vehicle under different weather and road conditions.
And S6, receiving and displaying ranking result information generated and sent by the server according to the vehicle test result data and the vehicle information. The ranking result information may include one or more of test ranking result information of 1-100 km acceleration, 100-0km braking distance test ranking result information, steering performance test ranking result information, and the like.
Further, when the vehicle information includes a vehicle type, receiving and displaying ranking result information generated and transmitted by the server according to the vehicle test result data and the vehicle information may include receiving and displaying ranking result information of the same vehicle type generated and transmitted by the server.
In addition, when the vehicle information includes a vehicle identifier for uniquely identifying the current vehicle, receiving and displaying ranking result information generated and transmitted by the server according to the vehicle test result data and the vehicle information may include receiving and displaying ranking result information of historical test result data of the current vehicle generated and transmitted by the server.
For example, taking the above test as a 1-100 km acceleration test as an example, a specific ranking method for national ranking of the same vehicle type is as follows:
after receiving the Vehicle test data (i.e., Vehicle test result data) and the Vehicle information sent by the Vehicle-mounted multimedia through the communication module, the server can analyze the Vehicle test data and the Vehicle information to obtain a Vehicle VIN (Vehicle identification number) number of the Vehicle, namely, a unique code, a Vehicle type, test time, a test place, time for accelerating for hundreds of kilometers, a maximum speed, displacement for reaching hundreds of kilometers, and the like. The vehicle type and the time spent in hundred kilometers acceleration are used for sequencing the test results, and the information such as VIN number, competition time, competition location, highest speed and displacement can be only used for displaying and used as additional information of the competition result.
Then, the server can store the data obtained by analysis into a preset test database, take out the test results of all vehicles from the preset test database according to the vehicle types, and arrange the test results into a list according to the time spent in accelerating for hundreds of kilometers and the size of the values from small to large. In addition, the Chinese characters can be classified according to 5 grades, namely the top 20% of the row names in the list can be five stars, the top 20% -40% can be four stars, the top 40% -60% can be three stars, the top 60% -80% can be two stars, and the rest can be one star.
