[0075] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0076] It should be noted that the terms "first", "second", etc. in the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0077] Figure 1 It is a schematic diagram of the implementation environment of a method for detecting a vehicle instrument provided by an embodiment of the present application. As Figure 1 shown, the implementation environment includes: a terminal device 101 and a vehicle instrument 102. The terminal device 101 and the vehicle instrument 102 are communicatively connected through a wired network. The terminal device 101 is powered on through a 220-volt (V) power supply. The terminal device 101 is used to execute the method for detecting a vehicle instrument provided by an embodiment of the present application.

[0078] Among them, the terminal device 101 is any electronic product that can perform human-computer interaction with a user in one or more ways such as a keyboard, a touchpad, a touch screen, a remote control, voice interaction, or a handwriting device. For example, the terminal device can be a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a PPC (Pocket PC), a tablet computer, a smart vehicle machine, a smart TV, a smart speaker, etc.

[0079] The vehicle instrument 102 includes a speedometer, a tachometer, a water temperature gauge, a fuel gauge, and so on.

[0080] Those skilled in the art should understand that the above-mentioned terminal device 101 and vehicle instrument 102 are only for illustrative purposes. Other existing or future terminal devices and vehicle instruments that are applicable to this application should also be included within the protection scope of this application and are hereby incorporated by reference.

[0081] An embodiment of this application provides a method for detecting a vehicle instrument. This method can be applied to the Figure 1 shown implementation environment. Taking Figure 2 the flowchart of a method for detecting a vehicle instrument provided by an embodiment of this application as an example, this method can be executed by the Figure 1 terminal device 101 in. As Figure 2 shown, this method includes the following steps 201 to step 205.

[0082] In step 201, a vehicle instrument detection interface is displayed, and at least one detection mode is displayed in the vehicle instrument detection interface.

[0083] Among them, any detection mode corresponds to a detection duration, an output voltage, and a detection frequency. Optionally, the output voltage corresponding to any detection mode can be one or multiple. That is to say, the output voltage corresponding to any detection mode can be fixed during the detection duration corresponding to any detection mode, or can change with the change of the detection duration. This application embodiment does not limit this.

[0084] In a possible implementation manner, when the terminal device is powered on and in an open state, the terminal device displays a vehicle instrument detection interface, and at least one detection mode is displayed in the vehicle instrument detection interface. As Figure 3 is a schematic diagram of a vehicle instrument detection interface provided by an embodiment of this application. Among them, four detection modes are displayed, namely detection mode one, detection mode two, detection mode three, and detection mode four.

[0085] Among them, any detection mode corresponds to a detection duration, an output voltage, and a detection frequency. Exemplarily, the detection duration corresponding to detection mode 1 is 1000 hours, the output voltage corresponding to detection mode 1 is 14 volts, and the detection frequency corresponding to detection mode 1 is 10 minutes. The detection duration corresponding to detection mode 2 is 2000 hours, the output voltage corresponding to detection mode 2 is 12 volts, and the detection frequency corresponding to detection mode 2 is 30 minutes. The detection duration corresponding to detection mode 3 is 144 hours. For the first 36 hours of the detection duration corresponding to detection mode 3, the output voltage is 13.5 volts; for the second 36 hours, the output voltage is 15 volts; for the third 36 hours, the output voltage is 13.5 volts; for the fourth 36 hours, the output voltage is 10.8 volts. The detection frequency corresponding to detection mode 3 is 5 minutes. The detection duration corresponding to detection mode 4 is 8 hours. For the first 150 minutes of the detection duration corresponding to detection mode 4, the output voltage is 12 volts; from the 150th minute to the 420th minute, the output voltage is 14 volts; from the 420th minute to the 480th minute, the output voltage is 12 volts.

[0086] It should be noted that the above detection mode 1 to detection mode 4 are only examples of the embodiments of the present application. The detection modes displayed on the vehicle instrument detection interface may also be other detection modes, and the embodiments of the present application do not limit this.

[0087] In step 202, in response to a trigger operation for a reference detection mode in at least one detection mode and receiving a detection instruction, within the detection duration corresponding to the reference detection mode, an output voltage corresponding to the reference detection mode is output to the vehicle instrument.

[0088] In a possible implementation manner, a start control is also displayed on the vehicle instrument detection interface. For example, Figure 3 301 in is the start control, and the start control is used to indicate the start of detection. In response to a trigger operation for a reference detection mode in at least one detection mode and a trigger operation for the start control, it is determined that a detection instruction is received, and then within the detection duration corresponding to the reference detection mode, an output voltage corresponding to the reference detection mode is output to the vehicle instrument. If a trigger operation for the reference detection mode has not been received before the trigger operation for the start control, a prompt message is displayed, and the prompt message is used to indicate the determination of the detection mode. That is, on the basis of determining the detection mode, the start control is triggered, and then within the detection duration corresponding to the determined detection mode, the output voltage corresponding to the determined detection mode is output to the vehicle instrument.

[0089] Optionally, when the reference detection mode is Detection Mode 1, upon receiving a detection instruction, a 14-volt voltage is output to the vehicle instrument within 1000 hours. When the reference detection mode is Detection Mode 2, upon receiving a detection instruction, a 12-volt voltage is output to the vehicle instrument within 2000 hours. When the reference detection mode is Detection Mode 3, upon receiving a detection instruction, a 13.5-volt voltage is output to the vehicle instrument in the first 36 hours, a 15-volt voltage in the second 36 hours, a 13.5-volt voltage in the third 36 hours, and a 10.8-volt voltage in the fourth 36 hours. When the reference detection mode is Detection Mode 4, upon receiving a detection instruction, a 12-volt voltage is output to the vehicle instrument in the first 150 minutes, a 14-volt voltage from the 150th minute to the 420th minute; and a 12-volt voltage from the 420th minute to the 480th minute.

[0090] Optionally, the vehicle instrument and the terminal device are communicatively connected via a wired network, and the terminal device outputs the output voltage corresponding to the reference detection mode to the vehicle instrument via the wired network. As Figure 4 are the front and back views of a terminal device provided by an embodiment of the present application. Figure 4 (1) in it is the front view of the terminal device. Figure 4 (2) in it is the back view of the terminal device, which shows Interface 1 401 and Interface 2 402. Among them, Interface 1 401 is used to power on the terminal device, and Interface 2 402 is used for the terminal device to connect to the vehicle instrument. Interface 2 402 includes 50 pins (respectively 1 - 50), and the meaning corresponding to each pin in Interface 2 402 is shown in Table 1 below.

SUBFUEL3 represents the 3rd gearbox oil temperature signal; SUBFUEL2 represents the 2nd gearbox oil temperature signal; SUBFUEL1 represents the 1st gearbox oil temperature signal. FUEL3- and FUEL3+ represent the 3rd fuel level signal; FUEL2- and FUEL2+ represent the 2nd fuel level signal; FUEL1- and FUEL1+ represent the 1st fuel level signal.

GND represents the ground signal.

[0095] In step 203, according to the detection frequency corresponding to the reference detection mode, multiple acquisition requests are sent to the vehicle instrument, and any one of the acquisition requests is used to acquire the current value of the vehicle instrument at the moment when any one of the acquisition requests is received.

[0096] In a possible implementation manner, after outputting the output voltage corresponding to the reference detection mode to the vehicle instrument in step 202 above, according to the detection frequency corresponding to the reference detection mode, multiple acquisition requests are sent to the vehicle instrument, and any one of the acquisition requests is used to acquire the current value of the vehicle instrument at the moment when any one of the acquisition requests is received.

[0097] Exemplarily, if the detection frequency corresponding to the reference detection mode is 30 minutes, the terminal device sends an acquisition request to the vehicle instrument every 30 minutes.

[0098] Optionally, the number of acquisition requests sent by the terminal device to the vehicle instrument is the maximum value among integers not greater than the target value. The target value is the quotient of the detection duration corresponding to the reference detection mode and the detection frequency corresponding to the reference detection mode. Exemplarily, if the detection duration corresponding to the reference detection mode is 1000 hours and the detection frequency corresponding to the reference detection mode is 0.5 hours, the number of acquisition requests sent by the terminal device to the vehicle instrument is 2000 times.

[0099] In a possible implementation, the terminal device sends multiple acquisition requests to the vehicle instrument at a communication rate of 250 kbps (kilobits per second).

[0100] Optionally, the terminal device sends multiple CAN (Controller Area Network) messages to the vehicle instrument according to the detection frequency corresponding to the reference detection mode, and each CAN message includes an acquisition request.

[0101] In step 204, receive the current values corresponding to each acquisition request returned by the vehicle instrument. The current value corresponding to any acquisition request refers to the current value of the vehicle instrument at the moment when the vehicle instrument receives any acquisition request.

[0102] In a possible implementation, after the vehicle instrument receives any acquisition request sent by the terminal device, the vehicle instrument determines the current value of the vehicle instrument at the moment when the vehicle instrument receives any acquisition request, uses the current value of the vehicle instrument at the moment when the vehicle instrument receives any acquisition request as the current value corresponding to any acquisition request, and then sends the current value corresponding to any acquisition request to the terminal device, so that the terminal device can obtain the current value corresponding to any acquisition request returned by the vehicle instrument. Since after the vehicle instrument receives each acquisition request, it will determine the current value of the vehicle instrument at the moment when the vehicle instrument receives each acquisition request, use the current value of the vehicle instrument at the moment when the vehicle instrument receives each acquisition request as the current value corresponding to each acquisition request, and then send the current value corresponding to each acquisition request to the terminal device, so that the terminal device can obtain the current value corresponding to each acquisition request returned by the vehicle instrument.

[0103] Optionally, after the terminal device receives the current values corresponding to each acquisition request, the terminal device can also sort the current values corresponding to each acquisition request according to the reference order according to the reception time of the current values corresponding to each acquisition request, obtain a sorting result, and store the sorting result in the terminal device for subsequent determination of the life detection result of the vehicle instrument according to the current values corresponding to each acquisition request. The reference sorting can be in the order from early to late or from late to early, and the embodiments of the present application do not limit this.

[0104] In step 205, based on the current values corresponding to each acquisition request, determine the life detection result of the vehicle instrument.

[0105] In a possible implementation, after obtaining the current values corresponding to each acquisition request, the process of determining the life detection result of the vehicle instrument based on the current values corresponding to each acquisition request includes: determining the absolute value of the difference between the current values corresponding to two adjacent acquisition requests according to the current values corresponding to each acquisition request; determining a first quantity of absolute values of differences between the current values corresponding to two adjacent acquisition requests that are greater than the absolute value of a reference value; based on the first quantity not being greater than a quantity threshold, determining that the life detection result of the vehicle instrument is qualified; based on the first quantity being greater than the quantity threshold, determining that the life detection result of the vehicle instrument is unqualified.

[0106] Wherein, both the reference value and the quantity threshold are set based on experience or adjusted according to the implementation environment, and the embodiments of the present application do not limit this. Exemplarily, the reference value is 5 and the quantity threshold is 10.

[0107] In a possible implementation, a detection duration box is also displayed in the vehicle instrument detection interface, and the detection duration box is used to display the duration required to detect the vehicle instrument, such as Figure 3 302 in is the detection duration box. In response to a trigger operation for a reference detection mode in at least one detection mode, display the detection duration corresponding to the reference detection mode in the detection duration box. By displaying the detection duration corresponding to the reference detection mode in the detection duration box, the user can know how long it takes to detect the vehicle instrument according to the reference detection mode, and thus the user can understand the duration required to detect the vehicle instrument.

[0108] Optionally, in response to a trigger operation for a reference detection mode in at least one detection mode, and when the number of output voltages corresponding to the reference detection mode is one, after displaying the detection duration corresponding to the reference detection mode in the detection duration box, if the user believes that the detection duration corresponding to the reference detection mode is too long, or the user believes that the detection duration corresponding to the reference detection mode is too short, the user can also modify the detection duration corresponding to the reference detection mode.

[0109] Optionally, in response to a trigger operation for the detection duration box, display a virtual keyboard, and multiple numeric controls and a confirmation control are displayed in the virtual keyboard, and any numeric control corresponds to a number; in response to a trigger operation for at least one numeric control in the virtual keyboard and a trigger operation for the confirmation control in the virtual keyboard, display a first value in the detection duration box, and the first value is the value determined by the trigger operation for at least one numeric control in the virtual keyboard. After receiving a detection instruction, output the output voltage corresponding to the reference detection mode within the duration of the first value.

[0110] In response to a trigger operation on the confirmation control, the virtual keyboard is cancelled from display. A cancellation control is also displayed in the virtual keyboard. When the user does not want to modify the detection duration corresponding to the reference detection mode, the user selects the cancellation control. In response to a trigger operation on the cancellation control, the virtual keyboard is cancelled from display. At this time, the detection duration box still displays the detection duration corresponding to the reference detection mode.

[0111] In another possible implementation, in response to a trigger operation on the reference detection mode in at least one detection mode, and if the number of output voltages corresponding to the reference detection mode is multiple, the detection duration corresponding to the reference detection mode is displayed in the detection duration box, and the user cannot change the detection duration corresponding to the reference detection mode. This is because there are multiple output voltages corresponding to the reference detection mode. During the detection duration corresponding to the reference detection mode, the voltages output to the vehicle instrument are different at different time periods. If the detection duration corresponding to the reference detection mode is modified, it will cause the voltages output to the vehicle instrument to be chaotic, and further make the detection result of the vehicle instrument inaccurate.

[0112] In a possible implementation, a detected duration box is also displayed in the vehicle instrument detection interface. The detected duration box is used to display the duration spent on detecting the vehicle instrument, such as Figure 3 303 in [the figure] is the detected duration box. In response to receiving a detection instruction, the time difference between the current time and the time when the detection instruction is received is determined; the time difference between the current time and the time when the detection instruction is received is displayed in the detected duration box. By displaying the time difference between the current time and the time when the detection instruction is received in the detected duration box, the user can know how long it has taken to detect the vehicle instrument.

[0113] In a possible implementation, a voltage box is also displayed in the vehicle instrument detection interface. The voltage box is used to display the voltage value output to the vehicle instrument, such as Figure 3 304 in [the figure] is the voltage box. In response to a trigger operation on the reference detection mode in at least one detection mode, when the output voltage corresponding to the reference detection mode is one, the output voltage corresponding to the reference detection mode is displayed in the voltage box. By displaying the output voltage corresponding to the reference detection mode in the voltage box, the user can know what the voltage output to the vehicle instrument is when detecting the vehicle instrument.

Optionally, an up adjustment control and a down adjustment control are also displayed in the vehicle instrument detection interface.

From the 420th minute to the 480th minute, the voltage output to the vehicle instrument is 12 volts. After receiving the detection instruction, when the detected duration is from 0 to 150 minutes, a 12-volt voltage is displayed in the voltage box; when the detected duration is from 150 minutes to 420 minutes, a 14-volt voltage is displayed in the voltage box; when the detected duration is from 420 minutes to 480 minutes, a 12-volt voltage is displayed in the voltage box.
