Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Embodiments of the present invention are directed to a data acquisition method based on a monitoring mode, and in the prior art, a general diagnosis mode is generally used to acquire internal data of a vehicle, and in order to highlight technical advantages of embodiments of the present invention, the general diagnosis mode and the monitoring mode are summarized as follows:
general diagnostic mode:
and after the hardware connection is finished, requesting connection to the vehicle-mounted computer, and establishing a bidirectional communication link after responding to a confirmation instruction of the vehicle-mounted computer. In the general diagnosis mode, the acquisition of the internal data of the vehicle is realized based on the interaction with the vehicle-mounted computer, and each request can be replied only once, and a plurality of requests are required for acquiring various internal data.
The advantage of the universal diagnostic mode is that unambiguous target data can be acquired. The disadvantages are that:
(1) if the vehicle-mounted computer is in a busy state, the vehicle-mounted computer cannot respond in time, so that internal data acquisition is delayed or even fails.
(2) Frequent inquiry can cause overload operation of a vehicle-mounted computer, and potential safety hazards of vehicles are brought, and the most common faults are that the vehicles report fault codes, safety air bag lamps are on, ESPs work abnormally, and the like. In severe cases, the vehicle-mounted computer may lock the engine for theft prevention or the like, so that the vehicle cannot be ignited.
(3) If the relevant instruction of the internal data of the vehicle is requested to the vehicle-mounted computer and sent wrongly, abnormal control on the computer can be caused, and the consequence cannot be predicted.
(4) Based on a protocol followed by a general diagnosis mode, the time interval of data query each time must be greater than 50MS, after query is sent, the vehicle-mounted computer needs 10-30 MS to give a reply on average, the time consumption of one interaction process is nearly 70MS, the vehicle internal data are obtained at the cost of consuming a large amount of time, and the timeliness is poor.
For example: taking the five types of data required to be acquired inside the vehicle as an example, if each data needs 70MS to be acquired, at least 350MS is required to acquire the five types of data. In the running process of the vehicle, the data in the vehicle needs to be acquired circularly, which means that more than 350MS intervals exist between each circle, which is not acceptable for application scenarios with high timeliness requirements. For example, when a normal vehicle starts to accelerate from a standstill, the vehicle speed should be displayed gradually from 0 to 9, and if the vehicle speed is delayed too much, the vehicle speed is displayed in a jump manner from 0 to 10 without transition, so that the user experience is remarkably reduced.
(5) In a general diagnosis mode, the type of internal data output by the vehicle-mounted computer is limited, about 20 types of data can be output according to different automobile manufacturers, about 5 to 6 types of data which can be normally used as a head-up display cannot meet the display requirement.
And a monitoring mode:
data transmitted in the vehicle internal network is monitored.
The disadvantage of the listening mode is that the data being listened to is original data and the target data cannot be obtained directly. The advantages are that:
(1) the one-way communication is not limited by the load state of the vehicle-mounted computer, the possibility of serious consequences caused by sending wrong instructions to the vehicle-mounted computer does not exist, and the interference to the vehicle-mounted computer is avoided.
(2) The method is not limited by the limitation of the universal diagnosis mode on the communication interval time, and the timeliness is better.
(3) The method is not limited by the output content of the vehicle-mounted computer in the universal diagnosis mode, and more kinds of internal data can be obtained.
Specifically, in order to evaluate the performance of acquiring the vehicle interior data based on the listening mode, the embodiment of the invention performs a lot of tests on the performance, and tests that the fastest group of data packets has an interval of only 5MS, and one group of data packets contains a plurality of different data. The data acquisition speed of the monitoring mode is more than tens of times of that of the general diagnosis mode.
Taking fox as an example, if the vehicle speed and the rotation speed are acquired in the general diagnosis mode, it is necessary to inquire the vehicle speed at an interval of 50MS, wait for 20MS to get a reply, then inquire the rotation speed at an interval of 50MS, wait for 20MS to get a reply, then wait for 50MS to inquire the vehicle speed, get a reply at an interval of 20MS, and so on, so that the time interval between two consecutive readings of the vehicle speed is 50+20+50+20+50+20 equals 210 MS. The monitoring mode only needs to monitor the data packet and analyze the vehicle speed and the rotating speed, and only needs 5MS for Fox.
When vehicle interior data is displayed, 24-frame pictures are displayed in 1 second based on the VGA video screen minimum standard, so that the influence of eyes is consistent, therefore, the change interval of the images is smaller than 41MS which is 1000/24, the universal diagnosis mode can not achieve the display speed at all, and the monitoring mode has no problem at all.
Further, in the embodiment of the present invention, based on the monitoring mode, a variety of vehicle internal data can be obtained, including but not limited to vehicle speed, rotation speed, water temperature, mileage, key status, seat belt status, hand brake status, accelerator status, foot brake status, dipped headlight status, high beam status, remaining fuel in the fuel tank, door status, lock status, radio status, air conditioner status, center control button, steering wheel angle, gear, clock, and reverse radar data.
The embodiment of the invention provides a vehicle speed data acquisition method based on a monitoring mode, which comprises the following steps of:
s101, starting the vehicle and keeping the vehicle in a static state.
S102, executing a preset filtering operation, and monitoring data in a first preset time for executing the filtering operation to obtain a data set.
Specifically, the preset filtering operation is: in the case of ensuring safety, various operations are performed on the vehicle, including, but not limited to, turning on headlights, turning left and right turn lights, placing safety belts, pulling handbrake, stepping on brakes, stepping on accelerator, steering wheel, etc.
Obtaining N data packets within a first preset time, wherein each data packet forms a data packet unit set, namely the data set obtained within the first preset time is a set of the N data packet unit sets.
S103, carrying out transverse comparison on each data packet unit set in the data set to obtain a first target range.
The filtering operation is intended to generate variation data other than vehicle speed and filter this part of data to reduce the interference of extracting vehicle speed data. Thus, in obtaining the first range, the changed data is first filtered out. Further, since the vehicle speed is zero, non-zero data is also filtered out, thereby obtaining the first target range.
And S104, extracting vehicle speed data from the first target range according to a preset rule.
The embodiment of the present invention further provides a method for extracting vehicle speed data from the first target range according to a preset rule, as shown in fig. 2, including:
s1041, running the vehicle to enable the vehicle speed value of the vehicle instrument to be increased by a preset step length to obtain a vehicle speed set value.
Specifically, the preset step length may be set by itself as needed, and may be 1, 5, or 10.
Further, the preset step size may also be a variable step size, which is only a certain and known value.
S1042, under the scene that the vehicle instrument displays the set value of the vehicle speed, monitoring data broadcasted by the vehicle-mounted computer to obtain a monitoring data set.
S1043, obtaining a first target range from the monitoring data set.
At the first execution of step S1043, the first target range is provided by step S103.
S1044, extracting data corresponding to the set value of the vehicle speed from the first target range to form a second target range.
As can be seen from the above, the data in the first target range is the suspected vehicle speed data, and the data corresponding to the set target value of the vehicle speed and the like is extracted from the suspected vehicle speed data, so that the range of the suspected vehicle speed data is further narrowed, and the second target range with a smaller range is obtained.
S1045, replacing the first target range with the second target range, and repeatedly executing the step S1041 until only one piece of data exists in the second target range.
And the only stored data is the monitored vehicle speed data.
According to the thought, the range of the suspected vehicle speed data is gradually reduced until the monitoring data corresponding to the vehicle speed data in the instrument one by one are accurately extracted, and the purpose of accurately knowing the vehicle speed through the monitoring data is achieved.
In the embodiment of the invention, dozens of vehicle types are monitored through a large number of tests, and the obtained test results show that monitoring data which are in one-to-one correspondence with the actual vehicle speed value exist in the monitoring data, and the vehicle speed of 10 systems obtained through different formulas according to the monitoring data and the vehicle speed data displayed in the instrument are in one-to-one correspondence.
Further, in practical applications, the vehicle speed obtaining method based on the monitoring mode according to the embodiment of the present invention further includes: and obtaining a 10-system actual vehicle speed value according to the monitored vehicle speed data, and displaying the actual vehicle speed value.
Furthermore, according to the obtained vehicle speed data, the actual vehicle speed value can be directly displayed on various terminal devices such as a head-up display, a mobile phone, a vehicle-mounted display screen and the like.
Further, an embodiment of the present invention further provides a vehicle speed reminding function method, as shown in fig. 3, including:
s301, monitoring vehicle data in real time.
S302, obtaining an actual vehicle speed value according to a monitoring result.
Specifically, the actual vehicle speed value obtained according to the monitoring result has been described in detail previously, and will not be described in detail herein.
And S303, acquiring an actual vehicle speed set value.
The actual vehicle speed set value may be set manually by a user, or may be obtained automatically, for example, a vehicle speed limit value of a certain road segment is obtained through networking, and the vehicle speed limit value is used as the actual vehicle speed set value.
Specifically, the user may set the actual vehicle speed setting value using a head-up display, a mobile phone, a vehicle-mounted terminal device, or the like.
S304, judging whether the actual vehicle speed value is not less than the actual vehicle speed set value.
S305, if yes, reminding the user.
Specifically, the actual vehicle speed value may be displayed on various terminal devices such as a head-up display, a mobile phone, and a vehicle-mounted display screen, and the reminder may also be displayed on various terminal devices such as a head-up display, a mobile phone, and a vehicle-mounted display screen.
Specifically, the reminding mode can be sound or light.
Further, an embodiment of the present invention further provides a display method of an accelerated timing function, as shown in fig. 4, including:
s401, responding to a preset trigger instruction, monitoring vehicle data in real time and acquiring an actual vehicle speed value.
Specifically, the actual vehicle speed value obtained according to the monitoring result has been described in detail previously, and will not be described in detail herein.
S402, recording actual vehicle speed values reaching a first preset threshold value v respectively0And a second preset threshold v1Time interval T.
S403, obtaining an average acceleration value
S404, displaying the average acceleration value and/or the time interval T.
The average acceleration value can be displayed on various terminal devices such as a head-up display, a mobile phone, a vehicle-mounted display screen and the like. Specifically, the average acceleration value may also be broadcasted by voice.
In a feasible implementation manner, the acceleration timing reminding function is specifically used for performing 0-100 KM/H acceleration timing, the head-up display reads vehicle speed data, when the vehicle speed is greater than 0, the head-up display is internally provided with a clock to start timing, the timing unit is millisecond, when the vehicle speed reaches 100KM/H, the timing is stopped, and the total time consumed by 0-100 KM/H is displayed.
This function can also be obtained by a general diagnostic method, but the general diagnostic method has a slow speed of reading data, and the time-consuming precision of the final result is not as good as that of a monitoring method. The vehicle speed read in the monitoring mode can be decimal according to different vehicle types, and the precision of some vehicle types can reach 80-th of KM/H, so that the precision of the average acceleration value obtained based on the monitoring mode is far higher than that of a general diagnosis mode.
