Detailed ways

In order to make the purpose, technical solutions, and advantages of this application clearer and clearer, the following further describes the application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.

The embodiment of this application solves the problem of poor detection accuracy and failure to detect battery aging in the one-time data collection method used in the prior art when detecting the capacity of the car battery, and realizes that the car ignition start can be screened out based on big data analysis. The minimum value of the process and the recovery time are used to determine the health status to detect the starting load of the car, which is convenient for users to collect data, and is helpful to improve the accuracy of judging the health status of the car battery. It can effectively detect the aging of the car battery in time. status. The method for detecting the starting load of an automobile provided by this embodiment will be described in detail below.

Fig. 1 is a detection method of automobile starting load provided by the present application. As shown in Fig. 1, the detection method includes:

In step S101, during the ignition start process of the automobile, the voltage information of the on-board automatic diagnosis system is collected through the high-frequency analog-to-digital converter.

Here, in the present embodiment, during the ignition start process of the automobile, the voltage information of the on-board automatic diagnostic system (On Board Diagnostics, OBD) is collected through a high-frequency analog-to-digital converter (Analog-to-Digital Converter, ADC for short). Optionally, the collection period is preferably 0.5 milliseconds, that is, starting from the ignition of the automobile, collecting once every 0.5 milliseconds, and continuing to collect until the ignition of the automobile ends, so as to obtain a set of OBD voltage information in the time period.

In step S102, the minimum voltage during the ignition start process of the automobile is obtained according to the voltage information.

In this embodiment, a group of OBD voltage information obtained in step S101 is analyzed, and the minimum value of the group of OBD voltage information is selected as the minimum voltage during the ignition start process of the automobile. Optionally, as shown in FIG. 2, the step S102 includes:

In step S201, the voltage information is added in the form of a node to a broken line graph with time information as the abscissa and voltage information as the ordinate to generate a voltage change curve.

In this embodiment, the voltage information is sorted in the manner of nodes according to the time development sequence, and a graph with time information as the abscissa and voltage information as the ordinate is generated. The broken line of the voltage change in this graph reflects the change trend of the OBD voltage information during the ignition start process of the car. As shown in FIG. 9, it is a schematic diagram of actual OBD voltage information provided by an embodiment of this application. In practical applications, at the moment the car engine starts, the car battery voltage is first pulled down, and then slowly rises to a higher voltage until the normal working voltage of the car battery is met, and the car battery is charged during the recovery process.

For ease of description, a specific example of this application is given below. It is assumed that the OBD voltage information collected during the ignition start process of the car includes:

12.2V, 12V, 11.9V, 11.5V, 11.4V, 11.3V, 10V, 9.1V, 10V, 11V, 10.5V, 11.2V, 11.6V, 12.2V;

The graph generated by big data methods, such as Excel, is shown in Figure 3.

In step S202, a ramp algorithm is used to analyze the voltage change curve to obtain a minimum voltage.

Among them, the hill-climbing algorithm is a method of local selection. The heuristic method is an improvement to the depth-first search. The feedback information is used to help generate the decision-making of the solution. Each time an optimal solution is selected from the adjacent solution space of the current solution. The solution is the current solution until it reaches a local optimal solution, which is a kind of artificial intelligence algorithm. In this embodiment, a climbing algorithm is used to analyze the voltage change curve, and the minimum value of voltage information is selected from the voltage change curve. Optionally, as shown in FIG. 4, the step S202 further includes:

In step S401, the voltage information when the vehicle ignition is started is selected as the starting point of the climbing algorithm.

Here, the voltage information when the automobile ignition is started refers to the first voltage information in a set of OBD voltage information collected above, that is, the OBD voltage information collected for the first time when the automobile ignition is started. In this embodiment, the voltage information is used as the starting point of the climbing algorithm. For example, the voltage information 12.2V collected at a time of 0 milliseconds in the example in Figure 3 above.

In step S402, the voltage information on the current node is compared with the voltage information of the next node, and the smaller value of the voltage information is obtained according to the comparison result.

Since this embodiment selects the minimum value, the climbing algorithm selects the smaller value of the two voltage information in each comparison.

In step S403, the smaller value is compared with the voltage information of the next node until the voltage information of the node is equal to the operating voltage.

Exemplarily, starting from the starting point of the climbing algorithm, the voltage information collected for the first time is compared with the voltage information collected for the second time to obtain the smaller value; and then the smaller value is used as the object of the next round of comparison , Compare with the voltage information collected for the third time, and so on. Until the voltage information collected at a certain time reaches the preset OBD voltage threshold, that is, the working voltage, the climbing algorithm is stopped. According to historical operating voltage experience after the car is started, the operating voltage fluctuates within a range, usually any value between 12 and 13V. When the OBD voltage information collected by the high-frequency analog-to-digital converter is equal to the working voltage, it is considered that the ignition start process of the automobile is over.

Continuing the previous example, if the working voltage is 12.2V, in the climbing algorithm process, first compare the voltage information 12.2V collected at t=0ms with the voltage information 12V collected at t=0.5ms, and take the smaller value of 12V and t =11.9V of the voltage information collected in 1ms is compared, and then 11.9V is compared with the voltage information 11.5V collected in t=1.5ms, and so on, until the voltage information 12.2V collected in t=6.5ms is greater than or equal to the voltage threshold, Then stop the climbing algorithm.

In step S404, the minimum value obtained by the current climbing algorithm is selected as the minimum voltage.

The minimum value selected according to the climbing algorithm is used as the minimum voltage during the ignition and starting process of the car. Following the previous example, the voltage information at t=3.5ms is 9.1V as the minimum voltage.

In step S103, the health status information of the car battery is obtained according to the minimum voltage, and the health status information is output.

Unlike the prior art, which judges the health state of the battery according to the capacity of the battery, this embodiment judges the health state of the battery according to the minimum voltage during the ignition and starting process of the car. As shown in FIG. 4, the step S103 includes:

In step S401, the minimum voltage is compared with a preset voltage threshold.

Wherein, the preset voltage threshold refers to the minimum voltage experience value during the starting process of the automobile, which is set according to historical experience, and may also be the average value of the minimum voltage in a specified historical time period. In this embodiment, the minimum voltage during the ignition start process of the current automobile is compared with the preset voltage threshold.

In step S402, the health status information of the car battery is generated according to the comparison result, and the health status information is output.

Specifically, when the minimum voltage is less than or equal to the preset voltage threshold, it indicates that the performance of the battery is good, and the health status information of the car battery is good; when the minimum voltage is greater than the preset voltage threshold , Indicating that the performance of the battery is poor, and the state of health of the car battery is poor.

According to the comparison result, the health status information of the car battery is generated, such as the battery performance is better, the battery performance is poor, and so on. As a preferred example of the present application, the state of health information of the battery can also be divided into multiple gradients according to the degree of deviation between the minimum voltage and the preset voltage threshold. For example, the minimum voltage is less than the preset voltage threshold and deviates from the preset voltage threshold. When the voltage threshold is larger, the battery performance is excellent; when the minimum voltage is less than the preset voltage threshold and deviates from the preset voltage threshold, the battery performance is better; when the minimum voltage is equal to the preset voltage threshold, the battery performance is average When the minimum voltage is greater than the preset voltage threshold and the deviation is small, the battery performance is poor and the battery needs to be replaced; when the minimum voltage is greater than the preset voltage threshold and the deviation from the preset voltage threshold is large , The battery performance is poor and the battery needs to be replaced.

The health status information is output to feed back the detection result to the user.

This embodiment is based on collecting a set of OBD voltage information during the ignition start process of the car, filtering out the minimum voltage among them, and judging the health status of the battery according to the minimum voltage, effectively avoiding the one-time data collection method used in the prior art The existence of the problem of poor detection accuracy is also conducive to timely detection of battery aging.

Optionally, as another preferred example of the present application, FIG. 5 is a detection method for the starting load of an automobile provided by the present application. As shown in FIG. 5, the detection method includes

From step S501 to step S502, step S501 to step S502 are the same as step S101 to step S102 described in the foregoing embodiment. For details, please refer to the description of the foregoing embodiment, which will not be repeated here. The detection method also includes:

In step S503, the recovery time of the vehicle from the minimum voltage to the working voltage is acquired.

According to the present embodiment, when the deviation of the OBD voltage information detected by the ADC from the conventional operating voltage is within a specified range, the vehicle is considered to have started ignition and enters the operating state, and the OBD voltage information at this time is used as the current operating voltage of the vehicle. Then calculate the time difference between the minimum voltage and the operating voltage to obtain the recovery time. Exemplarily, following the previous example, using 12.2V as the working voltage, the detected voltage information at t=3.5ms is 9.1V as the minimum voltage, and the working voltage of 12.2V appears at t=6.5ms, then calculate the time difference △ between the two t=6.5-3.5ms=3ms, as the rise time.

In step S504, the health status information of the car battery is obtained according to the rebound time, and the health status information is output.

Unlike the prior art, which judges the health state of the battery according to the capacity of the battery, this embodiment judges the health state of the battery according to the recovery time of the minimum voltage during the ignition start process of the automobile. As shown in FIG. 6, the step S504 includes:

In step S601, the change trend between the historical recovery time and the health status information is queried according to the recovery time.

Here, the present embodiment analyzes the historical recovery time and health status information in advance, and establishes a change trend between the historical recovery time and the health status information. Wherein, in the change trend between the historical recovery time and the health status information, the shorter the recovery time, the easier it is to charge the battery, and the better the battery performance, the better the health status of the car battery; the recovery time The longer it is, it indicates that it is difficult for the charge to enter and exit the battery, and the worse the performance of the battery, the worse the health of the car battery.

In this embodiment, the rebound voltage during the ignition start process of the current automobile is matched with the change trend between the historical rebound time and the health status information.

In step S602, the health status information of the car battery is generated according to the query result, and the health status information is output.

Specifically, the health status information of the car battery is generated according to the query result, such as good battery performance, poor battery performance, and so on. As a preferred example of the present application, the health status information of the battery can also be divided into multiple gradients according to the coverage of the recovery time. For example, according to the recovery time, the first gradient range, the second gradient range, and the third Gradient range, fourth step range, fifth gradient range, and define that the first gradient range corresponds to excellent battery performance, the second gradient range corresponds to better battery performance, the third step range corresponds to normal battery performance, and the fourth gradient range corresponds to The battery performance is poor, and the fifth gradient range corresponds to poor battery performance. When the recovery time falls within the first gradient range, the battery performance is excellent; when the recovery time falls within the second gradient range, the battery performance is better; when the recovery time falls within the third gradient range, the battery performance is average; the recovery time falls In the fourth gradient range, the battery performance is poor and the battery needs to be replaced; when the recovery time falls within the fifth gradient range, the battery performance is poor and the battery needs to be replaced.

This embodiment is based on collecting a set of OBD voltage information during the ignition and starting process of the car, filtering out the minimum voltage among them, and obtaining the rise time from the minimum voltage value to the working voltage, and judging the health status of the battery according to the rise time, effectively It avoids the problem of poor detection accuracy in the one-time data collection method in the prior art, and is also conducive to timely detection of the aging of the storage battery.
