The accompanying drawings are included to provide a description of preferred embodiments, and are not meant to limit the present application. Furthermore, the same reference numerals are intended to identify like components throughout the accompanying drawings.

DETAILED DESCRIPTION

[0027] Exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thoroughly and completely understood, and so that the scope of the present application will be fully conveyed to those skilled in the art.

[0028] In the vehicle manufacturing industry, whole vehicle factory detection is a key link to ensure that vehicles meet quality standards and safety specifications. In whole vehicle factory detection, a test vehicle is usually driven by a test personnel to each detection station of a whole vehicle factory detection flow line, and corresponding detection is performed on the vehicle at each detection station.

[0029] The drum detection station is a station in the whole vehicle factory detection flow line where drum detection is performed on a test vehicle. At the drum detection station, the wheels of the test vehicle can be driven to rotate by a drum, and the test vehicle is detected for retardation force, braking force, etc. to determine whether the retardation force, braking force, etc. of the test vehicle meet design requirements.

[0030] In the process of implementing the present application, the inventors found that, when performing drum detection of retardation force, braking force, etc. on a test vehicle, the test results were occasionally inaccurate. Through research on test vehicles that had inaccurate drum detection results of retardation force, braking force, etc., the inventors found that most of the test vehicles that had inaccurate drum detection results of retardation force, braking force, etc. were intelligent four-wheel drive vehicles. The intelligent four-wheel drive vehicles had inaccurate drum detection results of retardation force, braking force, etc. because the four-wheel drive system of the intelligent four-wheel drive vehicles automatically started the four-wheel drive mode during drum detection.

[0031] Specifically, an intelligent four-wheel drive system is configured in the intelligent four-wheel drive vehicle, and the intelligent four-wheel drive system automatically starts the four-wheel drive mode when there is a wheel speed difference between the wheels of the vehicle.

[0032] The drum detection station usually has two drums in front and back, respectively used to drive the front axle wheels and the rear axle wheels to rotate.

[0033] When detecting the braking force of the vehicle, the front axle wheels and the rear axle wheels of the vehicle are usually detected respectively.

[0034] When detecting the braking force of the front axle wheels of the vehicle, the front axle drum of the drum detection station drives the front axle wheels to rotate. When the front axle wheels rotate, a wheel speed difference appears between the front axle wheels and the rear axle wheels, which causes the four-wheel drive system of the vehicle to automatically start the four-wheel drive mode. After the four-wheel drive mode is started, the rotation of the front axle wheels drives the rear axle transmission system to rotate, which increases the braking force of the front axle wheels, resulting in that the detection result of the braking force of the front axle wheels is larger.

[0035] When detecting the braking force of the rear axle wheels of the vehicle, the rear axle drum of the drum detection station drives the rear axle wheels to rotate. When the rear axle wheels rotate, a wheel speed difference appears between the rear axle wheels and the front axle wheels, which causes the four-wheel drive system of the vehicle to automatically start the four-wheel drive mode. After the four-wheel drive mode is started, the rotation of the rear axle wheels drives the front axle transmission system to rotate, which increases the braking force of the rear axle wheels, resulting in that the detection result of the braking force of the rear axle wheels is larger.

[0036] Similarly, when detecting the braking force of the vehicle, the front axle wheels and the rear axle wheels of the vehicle are usually detected respectively.

[0037] When detecting the braking force of the front axle wheels of the vehicle, the front axle drum drives the front axle wheels to rotate, which causes a wheel speed difference to appear between the front axle wheels and the rear axle wheels. The wheel speed difference causes the four-wheel drive system to automatically start the four-wheel drive mode, and the rear axle transmission system is driven to rotate by the front axle wheels. The braking force of the front axle wheels is increased compared with that when the front axle wheels rotate alone, and the detection result of the braking force of the front axle wheels is larger.

[0038] When detecting the braking force of the rear axle wheels of the vehicle, the rear axle drum drives the rear axle wheels to rotate, which causes a wheel speed difference to appear between the rear axle wheels and the front axle wheels. The wheel speed difference causes the four-wheel drive system to automatically start the four-wheel drive mode, and the front axle transmission system is driven to rotate by the rear axle wheels. The braking force of the rear axle wheels is increased compared with that when the rear axle wheels rotate alone, and the detection result of the braking force of the rear axle wheels is larger.

[0039] Based on the above finding, the embodiment of the present application provides a drum test method and a vehicle. The drum test method and the vehicle provided by the embodiment of the present application can send a four-wheel drive disabling signal to the four-wheel drive system of the vehicle before the vehicle is subjected to drum test, so as to disable the four-wheel drive system from automatically starting the four-wheel drive mode, and then the vehicle is subjected to drum test. Thus, during the drum test of the vehicle, the four-wheel drive system of the vehicle will not automatically start the four-wheel drive mode, and the drum test result of the vehicle will not be inaccurate due to the automatic starting of the four-wheel drive mode.

[0040] Figure 1 is a flowchart of vehicle factory detection provided by some embodiments of the present application. As shown in Figure 1 the drum test method includes the following processing: S102, before the target vehicle is subjected to drum test, a four-wheel drive disabling signal is sent to the four-wheel drive system of the target vehicle, so as to disable the four-wheel drive system from automatically starting the four-wheel drive mode.

[0041] S104, the target vehicle is subjected to drum test.

[0042] In the above embodiment, the drum test can be a test based on a drum device at a drum test station in a vehicle factory detection flow line, which includes but is not limited to: retardation force detection, braking force detection. These detections are detections that may cause the four-wheel drive system to automatically start the four-wheel drive mode and result in inaccurate detection results in vehicle factory detection.

[0043] In some embodiments, the drum test is retardation force detection. The four-wheel drive disabling signal can be sent to the four-wheel drive system of the target vehicle before the target vehicle is subjected to retardation force detection, so as to disable the four-wheel drive system of the target vehicle from automatically starting the four-wheel drive mode, and then the target vehicle is subjected to retardation force detection. Thus, during the retardation force detection of the target vehicle, the four-wheel drive system of the vehicle will not automatically enter the four-wheel drive mode, the retardation force detection will not be affected by the automatic starting of the four-wheel drive mode, and the retardation force detection result will not be inaccurate due to the automatic starting of the four-wheel drive mode.

[0044] In some embodiments, the drum test is braking force detection. The four-wheel drive disabling signal can be sent to the four-wheel drive system of the target vehicle before the target vehicle is subjected to braking force detection, so as to disable the four-wheel drive system of the target vehicle from automatically starting the four-wheel drive mode, and then the target vehicle is subjected to braking force detection. Thus, during the braking force detection of the target vehicle, the four-wheel drive system of the vehicle will not automatically enter the four-wheel drive mode, the braking force detection will not be affected by the automatic starting of the four-wheel drive mode, and the braking force detection result will not be inaccurate due to the automatic starting of the four-wheel drive mode.

[0045] In some embodiments, the drum test includes the block force detection and the brake force detection. The block force detection and the brake force detection are performed in sequence. Before the target vehicle is subjected to a first detection of a plurality of detections including the block force detection and the brake force detection, a four-wheel drive disabling signal is sent to the four-wheel drive system of the target vehicle to disable the four-wheel drive system of the target vehicle from automatically starting the four-wheel drive mode; and then the target vehicle is subjected to the plurality of detections. In this way, during the plurality of detections including the block force detection and the brake force detection, the target vehicle does not automatically enter the four-wheel drive mode, the plurality of detections including the block force detection and the brake force detection are not affected by the automatic starting of the four-wheel drive mode, and the block force detection result and the brake force detection result are not inaccurate due to the automatic starting of the four-wheel drive mode.

[0046] The drum test method provided by the above embodiments sends a four-wheel drive disabling signal to the four-wheel drive system of the target vehicle before the target vehicle is subjected to the drum test, to disable the four-wheel drive system from automatically starting the four-wheel drive mode, and then the target vehicle is subjected to the drum test. In this way, during the drum test of the target vehicle, the four-wheel drive system of the target vehicle does not automatically start the four-wheel drive mode, and the drum test result of the target vehicle is not inaccurate due to the automatic starting of the four-wheel drive mode.

[0047] In the above embodiments, in the processing S102, before the target vehicle is subjected to the drum test, a four-wheel drive disabling signal is sent to the four-wheel drive system of the target vehicle to disable the four-wheel drive system from automatically starting the four-wheel drive mode. The four-wheel drive disabling signal can be sent to the four-wheel drive system of the target vehicle by the automatic control system of the vehicle factory test, or can be sent to the four-wheel drive system by the infotainment system of the target vehicle.

[0048] In some embodiments, the four-wheel drive disabling signal is sent to the four-wheel drive system of the target vehicle by the infotainment system of the target vehicle. The infotainment system of the target vehicle can be configured to: When the detection mode is turned on, send a four-wheel drive disabling signal to the four-wheel drive system of the target vehicle.

[0049] Wherein the detection mode can be manually turned on by the detection personnel operating the infotainment system, or can be automatically turned on by the infotainment system.

[0050] In some embodiments, the detection mode is manually turned on by the detection personnel operating the infotainment system. The infotainment system of the target vehicle is configured to: In response to the detection mode turning-on operation of the detection personnel, turn on the detection mode.

[0051] Wherein the target vehicle can provide one or more detection mode turning-on channels. The detection mode turning-on channels include but are not limited to: a screen turning-on channel, a voice turning-on channel, etc.

[0052] Exemplarily, the detection mode opening channel can include a screen opening channel. A detection mode opening option can be provided in a menu of a screen of a vehicle infotainment system of the target vehicle. Before drum detection such as block force detection and brake force detection is performed on the target vehicle, a detection personnel can find the detection mode opening option in the screen of the infotainment system of the target vehicle and click the detection mode opening option. In response to the clicking operation of the detection personnel on the detection mode opening option, the infotainment system of the target vehicle can open the detection mode. When the detection mode is opened, the infotainment system of the target vehicle can send a four-wheel drive disabling signal to a four-wheel drive system of the target vehicle. In response to the four-wheel drive disabling signal, the four-wheel drive system of the target vehicle can disable automatic starting of the four-wheel drive mode.

[0053] In order to avoid misoperation of the detection mode opening option by the user after the vehicle is delivered, the above-mentioned detection mode opening option can be set in a secondary menu of the infotainment system.

[0054] In the above-mentioned embodiment, the detection personnel performs the detection mode opening operation on the target vehicle before drum detection such as block force detection and brake force detection is performed on the target vehicle, so that the target vehicle opens the detection mode. In some cases, the detection personnel can forget to open the detection mode before drum detection such as block force detection and brake force detection is performed on the target vehicle.

[0055] In some embodiments, in order to avoid the detection personnel forgetting to open the detection mode before drum detection such as block force detection and brake force detection is performed on the target vehicle, the infotainment system of the target vehicle can be configured to: The detection mode opening prompt is performed in the following cases: The target vehicle is in the driving stage of the drum detection station, and the detection mode is not opened.

[0056] The detection mode opening prompt can be a prompt in a suitable form, such as a voice prompt, a text prompt, etc. For example, a prompt voice for opening the detection mode can be played, or a prompt text for opening the detection mode can be displayed on the screen of the infotainment system.

[0057] The driving stage of the drum detection station of the target vehicle can be a stage in which the target vehicle moves from the last detection station of the drum detection station to the drum detection station. In whole vehicle factory detection, the vehicle usually performs drum detection such as block force detection and brake force detection at the drum detection station. If the target vehicle is in the driving stage of the drum detection station, it means that the target vehicle is driving to the drum detection station, is about to enter the drum detection station, and is about to perform drum detection such as block force detection and brake force detection.

[0058] The infotainment system of the target vehicle can detect whether the target vehicle is in the driving stage of the drum detection station by a suitable method.

[0059] In some embodiments, the infotainment system of the target vehicle is configured to: In some embodiments, the infotainment system of the target vehicle is configured to: In some embodiments, the infotainment system of the target vehicle is configured to:

[0060] In some embodiments, the infotainment system of the target vehicle is configured to:

[0061] In some embodiments, the infotainment system of the target vehicle is configured to:

[0062] In some embodiments, the infotainment system of the target vehicle is configured to:

[0063] In some embodiments, the infotainment system of the target vehicle is configured to:

[0064] In some embodiments, the infotainment system of the target vehicle is configured to: In some embodiments, the infotainment system of the target vehicle is configured to: In some embodiments, the infotainment system of the target vehicle is configured to:

[0065] In some embodiments, the infotainment system of the target vehicle is configured to: In some embodiments, the infotainment system of the target vehicle is configured to:

[0066] The infotainment system of the target vehicle can detect whether the target vehicle is in the just-in-place phase of the drum detection station by a proper method.

[0067] In some embodiments, the infotainment system of the target vehicle can be configured to: The target vehicle is in the just-in-place phase of the drum detection station is determined when: The target vehicle is in the just-in-place phase of the drum detection station is determined when:

[0068] Exemplarily, when it is detected that the target vehicle is in the just-in-place phase of the drum detection station, the infotainment system of the target vehicle can continue to detect the current speed of the target vehicle. If it is detected that the current speed is less than 1 km / h, such as 0, and the engine is off, the infotainment system of the target vehicle can determine that the target vehicle is parked and enters the drum detection station and is in the just-in-place phase of the drum detection station.

[0069] When the target vehicle is subjected to the whole-vehicle delivery detection, the infotainment system of the target vehicle can detect whether the detection mode is started when it is detected that the target vehicle is currently in the just-in-place phase of the drum detection station. If the detection mode is not started, it indicates that the detection personnel still forgets to start the detection mode after being prompted to start the detection mode. At this time, the infotainment system can automatically start the detection mode. After the detection mode is automatically started, the infotainment system can give a prompt that the detection mode has been automatically started to prompt the detection personnel that the detection mode has been automatically started. The prompt that the detection mode has been automatically started can be stopped after a specified time period.

[0070] In the above embodiments, by configuring the infotainment system of the target vehicle to start the detection mode when the target vehicle is in the just-in-place phase of the drum detection station and the detection mode is not started, the detection mode can be automatically started by the detection mode starting mechanism built in the infotainment system of the target vehicle, preventing the detection personnel from forgetting to start the detection mode before the drum detection such as the blocking force and the braking force.

[0071] In the above embodiments, the detection mode starting prompt mechanism and the detection mode automatic starting mechanism built in the infotainment system of the target vehicle and other multiple detection mode missing starting mechanisms can ensure that the detection mode is started before the drum detection.

[0072] In the above embodiments, the infotainment system of the target vehicle is configured to send a four-wheel drive disabling signal to the four-wheel drive system of the target vehicle when the detection mode is started. Correspondingly, the four-wheel drive system of the target vehicle can be configured to disable the automatic starting of the four-wheel drive mode in response to the four-wheel drive disabling signal.

[0073] The four-wheel drive system of the target vehicle can be prohibited from automatically starting the four-wheel drive mode by a proper manner. In some embodiments, the four-wheel drive system of the target vehicle can be configured to: In response to the four-wheel drive disabling signal, torque loading is prohibited to prohibit the automatic starting of the four-wheel drive mode.

[0074] Torque loading is a process of transmitting the torque of the engine of the vehicle to the front and rear axles of the vehicle. For different four-wheel drive systems, the strategies for the automatic starting of the four-wheel drive mode can be different, but no matter what strategy is adopted for the automatic starting of the four-wheel drive mode, the torque of the engine of the vehicle is ultimately transmitted to the front and rear axles of the vehicle to realize the starting of the four-wheel drive mode. In the above embodiments, the four-wheel drive system of the target vehicle is configured to prohibit torque loading in response to the four-wheel drive disabling signal, and no matter what strategy is adopted for the automatic starting of the four-wheel drive mode, the effect of prohibiting the automatic starting of the four-wheel drive mode can be achieved.

[0075] In the above embodiments, before the drum test is performed on the target vehicle, the four-wheel drive disabling signal is sent to the four-wheel drive system of the target vehicle to prohibit the automatic starting of the four-wheel drive mode by the four-wheel drive system, so that the four-wheel drive system of the target vehicle will not automatically start the four-wheel drive mode during the drum test, and the drum test result of the target vehicle will not be inaccurate due to the automatic starting of the four-wheel drive mode. Further, to ensure that the vehicle restores normal four-wheel drive function when it is shipped, in some embodiments of the present application, the drum test method further comprises: After the drum test is performed on the target vehicle, the four-wheel drive recovery signal is sent to the four-wheel drive system to allow the four-wheel drive system to automatically start the four-wheel drive mode.

[0076] The four-wheel drive recovery signal can be sent to the four-wheel drive system by the automatic control system of the vehicle factory test, or can be sent to the four-wheel drive system by the infotainment system of the target vehicle.

[0077] In some embodiments, the four-wheel drive recovery signal is sent to the four-wheel drive system by the infotainment system of the target vehicle. The infotainment system of the target vehicle can be configured to: When the detection mode is off, the four-wheel drive recovery signal is sent to the four-wheel drive system of the target vehicle.

[0078] The detection mode can be manually closed by the detection personnel operating the infotainment system, or can be automatically closed by the infotainment system.

[0079] In some embodiments, the detection mode is manually closed by the detection personnel operating the infotainment system. The infotainment system of the target vehicle is configured to close the screen channel and the voice channel.

[0080] Exemplarily, the detection mode closing channel can include a screen closing channel. A detection mode closing option can be provided in a menu of a screen of a vehicle machine system of the target vehicle. After the drum detection such as the block force detection, the brake force detection, etc. of the target vehicle is completed, the detection personnel can find the detection mode closing option in the screen of the vehicle machine system of the target vehicle and click the detection mode closing option. In response to the clicking operation of the detection personnel on the detection mode closing option, the vehicle machine system of the target vehicle can close the detection mode. When the detection mode is closed, the vehicle machine system of the target vehicle can send a four-wheel drive recovery signal to the four-wheel drive system of the target vehicle. In response to the four-wheel drive recovery signal, the four-wheel drive system of the target vehicle can allow the four-wheel drive mode to be automatically started.

[0081] The detection mode closing option can be set in a secondary menu of the vehicle machine system.

[0082] In the above embodiment, after the drum detection such as the block force detection, the brake force detection, etc. of the target vehicle is completed, the detection personnel performs the detection mode closing operation to make the vehicle machine system of the target vehicle close the detection mode. In some cases, after the drum detection such as the block force detection, the brake force detection, etc. of the target vehicle is completed, the detection personnel can forget to close the detection mode.

[0083] In some embodiments, to avoid the detection personnel forgetting to close the detection mode after the drum detection such as the block force detection, the brake force detection, etc. of the target vehicle is completed, the vehicle machine system of the target vehicle can be configured to: The detection mode closing prompt is performed in the following case: The target vehicle is in the driving-off stage of the drum detection station, and the detection mode is not closed.

[0084] The detection mode closing prompt can be a prompt in a suitable form, such as a voice prompt, a text prompt, etc. For example, a prompt voice for closing the detection mode can be played, or a prompt text for closing the detection mode can be displayed on the screen of the vehicle machine system.

[0085] The target vehicle being in the driving-off stage of the drum detection station can mean that the target vehicle has left the drum detection station but has not yet left the whole vehicle factory detection flow line.

[0086] In the whole vehicle factory detection, the vehicle usually performs the drum detection such as the block force detection, the brake force detection, etc. in the drum detection station. If the target vehicle is in the driving-off stage of the drum detection station, it means that the target vehicle has completed all the detections in the drum detection station, and the drum detection such as the block force detection, the brake force detection, etc. in the drum detection station has been completed. The vehicle machine system of the target vehicle can detect whether the target vehicle is in the driving-off stage of the drum detection station by a suitable method.

[0087] In some embodiments, the vehicle machine system of the target vehicle can be configured to: In the following case, it is determined that the target vehicle is in the driving-off stage of the drum test station: The current vehicle mileage of the target vehicle is greater than a first mileage threshold and less than a second mileage threshold.

[0088] Illustratively, a vehicle is usually completed on a production line. In the whole vehicle delivery test, the vehicle is usually driven by a test personnel from the production line to each test station of the whole vehicle delivery test line in sequence for corresponding tests. The distance from the production line to the drum test station is fixed. The infotainment system of the target vehicle can detect the current vehicle mileage of the target vehicle. If the current vehicle mileage is greater than a first mileage threshold and less than a second mileage threshold, it can be determined that the target vehicle has currently left the drum test station, and is in the driving-off stage of the drum test station.

[0089] The first mileage threshold can be determined according to the distance from the position where the vehicle is completed to the drum test station. The second mileage threshold can be determined according to the distance from the position where the vehicle is completed on the production line to each test station of the whole vehicle delivery test line for completing all tests of the whole vehicle delivery test.

[0090] In actual applications, the shutdown prompt of the test mode does not need to be accurately controlled. The first mileage threshold can be greater than the distance from the position where the vehicle is completed to the drum test station. The mileage threshold can be an estimated mileage, for example, 2 km. The second mileage threshold can be greater than the distance from the position where the vehicle is completed on the production line to each test station of the whole vehicle delivery test line for completing all tests of the whole vehicle delivery test. The mileage threshold can be an estimated mileage, for example, 3 km.

[0091] When the whole vehicle delivery test is performed on the target vehicle, the infotainment system of the target vehicle can detect whether the test mode is closed when it is detected that the target vehicle is in the driving-off stage of the drum test station. If the test mode is not closed, it means that the test personnel forgets to close the test mode after the drum test such as the blocking force test and the braking force test. The infotainment system can perform a test mode shutdown prompt. The test personnel can manually close the test mode according to the test mode shutdown prompt. After the test personnel manually closes the test mode, the infotainment system can stop performing the test mode shutdown prompt.

[0092] In the above embodiment, by configuring the infotainment system of the target vehicle to perform a test mode shutdown prompt when the target vehicle is in the driving-off stage of the drum test station and the test mode is not closed, the test personnel can be prompted to close the test mode after the drum test on the target vehicle through the prompt mechanism built in the infotainment system of the target vehicle, so as to prevent the test personnel from forgetting to close the test mode.

[0093] In some cases, the target vehicle may still forget to turn off the detection mode after the detection mode off prompt.

[0094] In some embodiments, the infotainment system of the target vehicle can be configured to: turn off the detection mode when: the target vehicle is in a departure stage of a whole vehicle delivery detection flow line, and the detection mode is not turned off.

[0095] The target vehicle being in the departure stage of the whole vehicle delivery detection flow line can mean that the target vehicle has already left the whole vehicle delivery detection flow line. In the whole vehicle delivery detection, the vehicle usually needs to complete all detections in the whole vehicle delivery detection flow line before leaving the whole vehicle delivery detection flow line. If the target vehicle is in the departure stage of the whole vehicle delivery detection flow line, it means that the target vehicle has completed all detections in the whole vehicle delivery detection flow line and is about to be delivered.

[0096] The infotainment system of the target vehicle can detect whether the target vehicle is in the departure stage of the whole vehicle delivery detection flow line through appropriate methods.

[0097] In some embodiments, the infotainment system of the target vehicle can be configured to: determine that the target vehicle is in the departure stage of the whole vehicle delivery detection flow line when: the current vehicle mileage of the target vehicle is greater than a second mileage threshold.

[0098] For example, the infotainment system of the target vehicle can detect whether the current vehicle mileage of the target vehicle is greater than the second mileage threshold. If the current vehicle mileage is greater than the second mileage threshold, it can be determined that the target vehicle has left the whole vehicle delivery detection flow line and is in the departure stage of the whole vehicle delivery detection flow line.

[0099] The second mileage threshold can be determined according to the distance from the position where the vehicle is completed in the production flow line to each detection station of the whole vehicle delivery detection flow line, and the distance of completing all detections of the whole vehicle delivery detection. It can be an estimated mileage, such as 3km.

[0100] In the above embodiments, by configuring the infotainment system of the target vehicle to turn off the detection mode when the target vehicle is in the departure stage of the whole vehicle delivery detection flow line and the detection mode is not turned off, the detection mode can be automatically turned off through the built-in anti-off mechanism of the infotainment system of the target vehicle, and the detection mode can be ensured to be turned off after the target vehicle completes all detections of the whole vehicle delivery detection.

[0101] In the above embodiments, the multiple anti-detection mode leakage closing mechanisms such as the detection mode closing prompt mechanism and the detection mode automatic closing mechanism built in the infotainment system of the target vehicle can ensure that the detection mode is closed after all the detections of the whole vehicle factory detection of the target vehicle are completed.

[0102] In the above embodiments, the infotainment system of the target vehicle is configured to send a four-wheel drive recovery signal to the four-wheel drive system of the target vehicle when the detection mode is closed. Accordingly, the four-wheel drive system of the target vehicle can be configured to allow the automatic start of the four-wheel drive mode in response to the four-wheel drive recovery signal.

[0103] In some embodiments, the four-wheel drive system of the target vehicle can be configured to: allow torque loading in response to the four-wheel drive recovery signal to allow the automatic start of the four-wheel drive mode.

[0104] In the above embodiments, the target vehicle is appropriately configured to allow the detection personnel to interact with the target vehicle during the whole vehicle factory detection, so as to prohibit the automatic start of the four-wheel drive mode of the target vehicle during the drum detection of the target vehicle, and prevent the drum detection result of the target vehicle from being affected by the automatic start of the four-wheel drive mode. Figure 2 is a schematic diagram of the interaction process of the drum detection method provided by some embodiments of the present application. Now, the drum detection method provided by the embodiments of the present application will be further described in combination with the interaction process shown in Figure 2 .

[0105] As shown in Figure 2 , in some embodiments of the present application, the target vehicle is an intelligent four-wheel drive vehicle which can automatically start the four-wheel drive mode. The drum detection method includes the following interaction process: S202, the infotainment system of the target vehicle performs a detection mode opening prompt when it is detected that the target vehicle is in the driving stage of the drum detection station and the detection mode is not opened.

[0106] As an example, the car machine system can set a detection mode signal A, if the value of the detection mode signal A is 0X1, it indicates that the detection mode is opened, if the value of the detection mode signal A is 0X2, it indicates that the detection mode is closed. And the car machine system can set a prompt signal G, if the value of the prompt signal G is 0X1, the car machine system screen can not make a prompt; if the value of the prompt signal G is 0X2, the car machine system screen can display a detection mode closed prompt "please click to exit the detection mode"; if the value of the prompt signal G is 0X3, the car machine system screen can display a detection mode automatically closed prompt "the detection mode has been automatically exited for you"; if the value of the prompt signal G is 0X4, the car machine system screen can display a detection mode opened prompt "please click to enter the detection mode"; if the value of the prompt signal G is 0X5, the car machine system screen can display a detection mode automatically opened prompt "the detection mode has been automatically entered for you".

[0107] The car machine system can detect whether the vehicle has completed all detections on the last station of the drum detection station, if yes, the car machine system can detect whether the current speed of the vehicle is greater than the first speed threshold 5km / h, if yes, the car machine system can determine that the target vehicle is in the driving stage of the drum detection station. In the case that the target vehicle is in the driving stage of the drum detection station, the car machine system can detect whether the value of the detection mode signal A is 0X1 to detect whether the detection mode has been opened, if the value of the detection mode is not 0X1, the car machine system can set the value of the prompt signal G to 0X4, so that the car machine system screen displays a detection mode opened prompt "please click to enter the detection mode". The detection personnel can perform a detection mode opening operation by clicking the detection mode opening option on the car machine system screen.

[0108] After displaying the detection mode opened prompt "please click to enter the detection mode", if the detection personnel performs a detection mode opening operation on the car machine system screen, execute process S204, if the detection personnel does not perform a detection mode opening operation on the car machine system screen, execute process S206.

[0109] S204, the car machine system of the target vehicle opens the detection mode in response to the detection mode opening operation of the detection personnel.

[0110] Following the above example, the car machine system can set the value of the detection mode signal A to 0X1 to open the detection mode and set the value of the prompt signal G to 0X1 to make the car machine system screen stop displaying the detection mode opened prompt in response to the detection mode opening operation performed by the detection personnel on the car machine system screen.

[0111] S206, the car machine system of the target vehicle automatically starts the detection mode in the case that the target vehicle is in the just-in-place stage of the drum detection station and the detection mode is not opened.

[0112] Continuing with the above example, the car machine system can detect whether the current vehicle speed of the vehicle is 0, and detect whether the engine of the vehicle is off, if the current vehicle speed of the vehicle is 0, and the engine of the vehicle is off, the car machine system can determine that the vehicle is in the just-in-place phase of the drum detection station. In the case where the vehicle is in the just-in-place phase of the drum detection station, the car machine system can detect whether the value of the detection mode signal A is 0X1 to detect whether the detection mode is started, if the value of the detection mode signal A is not 0X1, it means that the detection mode is not started, the car machine system can set the value of the detection mode signal A to 0X1 to start the detection mode, and set the value of the prompt signal G to 0X5, so that the car machine system screen displays the detection mode automatic start prompt "automatic start detection mode for you".

[0113] S208, the car machine system of the target vehicle sends a four-wheel drive disable signal to the four-wheel drive system of the target vehicle when the detection mode is started.

[0114] Continuing with the above example, the car machine system can determine that the detection mode is started when the value of the detection mode signal A becomes 0X1, and send a four-wheel drive disable signal to the four-wheel drive system.

[0115] S210, the four-wheel drive system of the target vehicle responds to the four-wheel drive disable signal to disable the automatic start of the four-wheel drive mode.

[0116] Continuing with the above example, the four-wheel drive system can respond to the four-wheel drive disable signal sent by the car machine system to disable torque loading to disable the automatic start of the four-wheel drive mode.

[0117] In the case where the detection mode has been started and the automatic start of the four-wheel drive mode has been disabled, the detection personnel can perform drum detection such as braking force detection and braking force detection on the target vehicle, and perform detection mode closing operation on the car machine system screen after the detection is completed.

[0118] S212, the car machine system of the target vehicle performs detection mode closing prompt when it is detected that the target vehicle is in the driving-off phase of the drum detection station and the detection mode is not closed.

[0119] Continuing with the above example, the car machine system can detect the current vehicle mileage of the vehicle, if the current vehicle mileage of the vehicle is greater than the first mileage threshold 2km and less than the second mileage threshold 3km, the car machine system can determine that the vehicle is in the driving-off phase of the drum detection station. When the vehicle is in the driving-off phase of the drum detection station, the car machine system can detect whether the value of the detection mode signal A is 0X2 to detect whether the detection mode is closed. If the value of the detection mode signal A is not 0X2, it means that the detection mode is not closed, the car machine system can set the value of the prompt signal G to 0X2, so that the car machine system screen displays the detection mode closing prompt "please click to exit the detection mode".

[0120] After the prompt is displayed, if the tester clicks the detection mode closing option on the car machine system screen and performs a detection mode closing operation, the process S214 is executed, and if the tester does not click the detection mode closing option on the car machine system screen and does not perform a detection mode closing operation, the process S216 is executed.

[0121] In the process S214, the car machine system of the target vehicle closes the detection mode in response to the detection mode closing operation of the tester.

[0122] In the above example, the car machine system can set the value of the detection mode signal A to 0X2 to close the detection mode and set the value of the prompt signal G to 0X1 to stop the car machine system screen from displaying the detection mode closing prompt in response to the detection mode closing operation of the tester on the car machine system screen.

[0123] In the process S216, the car machine system of the target vehicle automatically closes the detection mode when it is detected that the target vehicle is in the driving-off stage of the whole vehicle factory detection flow line and the detection mode is not closed.

[0124] In the above example, the car machine system can detect the current vehicle mileage of the vehicle, and if the current vehicle mileage is greater than the second mileage threshold 3km, the car machine system can determine that the vehicle is in the driving-off stage of the whole vehicle factory detection flow line. When the vehicle is in the driving-off stage of the whole vehicle factory detection flow line, the car machine system can detect whether the value of the detection mode signal A is 0X2 to detect whether the detection mode is closed. If the value of the detection mode signal A is not 0X2, it means that the detection mode is not closed, and the car machine system can set the value of the detection mode signal A to 0X2 to close the detection mode and set the value of the prompt signal G to 0X3 to make the car machine system screen display the detection mode automatic closing prompt “The detection mode has been automatically exited for you”.

[0125] In the process S218, the car machine system of the target vehicle sends a four-wheel drive recovery signal to the four-wheel drive system of the target vehicle when the detection mode is closed.

[0126] In the above example, the car machine system can send a four-wheel drive recovery signal to the four-wheel drive system of the target vehicle when the value of the detection mode signal A becomes 0X2.

[0127] In the process S220, the four-wheel drive system of the target vehicle allows the automatic start of the four-wheel drive mode in response to the four-wheel drive recovery signal.

[0128] In the above example, the four-wheel drive system can allow torque loading in response to the four-wheel drive recovery signal to allow the automatic start of the four-wheel drive mode.
