[0052] For the purposes of the present application, the technical solutions and advantages thereof will be more clearly apparent from the following further detailed description of the embodiments, evidently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0053] With the enhancement of people's environmental protection awareness, people's requirements for vehicle exhaust emission are higher and higher, and exhaust emission regulations are more and more stringent, and vehicles need to meet the requirements of exhaust emission and fuel consumption and other performance indicators. Therefore, in the vehicle development process, the vehicle needs to be tested on the drum test bench to determine the vehicle's exhaust emission, fuel consumption and other performance indicators. However, in the current drum test process, the vehicle's brake system alarm will cause the vehicle's energy recovery device to be unable to activate, thereby causing the vehicle's energy recovery device to be unable to work normally, affecting the accuracy of the drum test. Specifically, the vehicle's energy recovery device is used to convert the mechanical energy of the vehicle during braking into electrical energy to provide energy for the vehicle. During the fuel consumption test of the vehicle, if the vehicle's energy recovery device cannot work normally, the vehicle needs to consume a large amount of fuel to travel to the fixed mileage for fuel consumption test, resulting in a higher fuel consumption of the vehicle obtained by the test.

[0054] The embodiment of the present application provides a drum test preprocessing method and device, and the drum test preprocessing method is executed by a drum test preprocessing device arranged in a vehicle. After the vehicle is carried to a drum test bench, the drum test preprocessing device receives an activation instruction for activating the drum test and judges whether the vehicle meets the drum test condition by responding to the activation instruction. In the case where the vehicle meets the drum test condition, the drum test preprocessing device prohibits the vehicle's brake system alarm, and activates the drum test to test the vehicle on the drum. The embodiment of the present application prohibits the vehicle's brake system alarm before the vehicle is tested on the drum, avoids the vehicle's energy recovery device being unable to activate due to the vehicle's brake system alarm during the drum test of the vehicle, ensures that the vehicle's energy recovery device can work normally during the drum test, and thus ensures the accuracy of the drum test.

[0055] The embodiments of the drum test preprocessing method of the present application will be described below.

[0056] Reference is made to Figure 1 FIG. 1 shows a flowchart of a drum test pre-processing method according to an embodiment of the present application. The drum test pre-processing method is performed by a drum test pre-processing device deployed in a vehicle. The drum test pre-processing device can be an integrated power brake (IPB) of the vehicle. Referring to Figure 1 The drum test pre-processing method includes the following steps S101-S104.

[0057] S101. After the vehicle is carried to a drum test bench, an activation instruction for activating a drum test is received.

[0058] The drum test bench can be a four-wheel drive drum test bench or a two-wheel drive drum test bench.

[0059] After the vehicle is carried to the drum test bench, for example, after the vehicle is pushed to the drum test bench by a user, the user operates an ignition switch of the vehicle to place the ignition switch of the vehicle in an ON gear, so that a power module of the vehicle supplies power to other electrical components of the vehicle. Then, the user triggers the activation instruction for activating the drum test by operating the vehicle, and the drum test pre-processing device receives the activation instruction.

[0060] In an optional embodiment, the vehicle includes a human-machine interaction component, and the user triggers the activation instruction for activating the drum test through the human-machine interaction component. In a specific embodiment, the user selects a drum test item through the human-machine interaction component to trigger the activation instruction for activating the drum test, and the drum test pre-processing device receives the activation instruction. The human-machine interaction component can include a voice interaction component, a touch display component, etc. The voice interaction component can include a microphone, and the touch display component can include a touch display screen.

[0061] In one embodiment, the human-machine interaction component of the vehicle includes a touch display component, and the user operates the touch display component to make the touch display component display a test item interface. The test item interface includes at least one test item control, each test item control corresponds to a test item, and the at least one test item control includes a drum test control. The user triggers the activation instruction for activating the drum test through the drum test control. For example, the user clicks the drum test control to trigger the activation instruction for activating the drum test.

[0062] As an example, as Figure 2As shown in FIG. 1, a schematic diagram of a test item interface provided by an embodiment of the present application is shown. The test item interface includes test item controls 1-n, each of which corresponds to a test item 1-n. Each of the test item controls 1-n is configured to trigger an activation instruction for the test item corresponding to the test item control. For example, the user clicks the test item control 3 to trigger an activation instruction for the drum test. The drum test preprocessing device receives the activation instruction. In an optional embodiment, after receiving the activation instruction, the drum test preprocessing device displays, according to the activation instruction, an activation verification interface as shown in FIG. 2, which includes a password input box and a confirm button. After the user inputs a verification password in the password input box and clicks the confirm button, a verification instruction is triggered, which carries the verification password input by the user. The drum test preprocessing device receives the verification instruction. The drum test preprocessing device determines whether the verification password carried by the verification instruction matches a preset password. In the case where the verification password matches the preset password, the drum test preprocessing device determines that the activation verification is successful. In the case where the verification password does not match the preset password, the drum test preprocessing device determines that the activation verification fails. Figure 3 As shown in FIG. 1, a schematic diagram of a test item interface provided by an embodiment of the present application is shown. The test item interface includes test item controls 1-n, each of which corresponds to a test item 1-n. Each of the test item controls 1-n is configured to trigger an activation instruction for the test item corresponding to the test item control. For example, the user clicks the test item control 3 to trigger an activation instruction for the drum test. The drum test preprocessing device receives the activation instruction. In an optional embodiment, after receiving the activation instruction, the drum test preprocessing device displays, according to the activation instruction, an activation verification interface as shown in FIG. 2, which includes a password input box and a confirm button. After the user inputs a verification password in the password input box and clicks the confirm button, a verification instruction is triggered, which carries the verification password input by the user. The drum test preprocessing device receives the verification instruction. The drum test preprocessing device determines whether the verification password carried by the verification instruction matches a preset password. In the case where the verification password matches the preset password, the drum test preprocessing device determines that the activation verification is successful. In the case where the verification password does not match the preset password, the drum test preprocessing device determines that the activation verification fails.

[0063] In another embodiment, the human-computer interaction component of the vehicle includes a voice interaction component. The user triggers an activation instruction for activating the drum test through the voice interaction component. For example, the user speaks a voice segment "activate the drum test" within a preset distance of the voice interaction component to trigger the activation instruction. The drum test preprocessing device analyzes the activation instruction to obtain the voice segment, and determines that the user wants to activate the drum test according to the voice segment.

[0064] S102. In response to the activation instruction, it is determined whether the vehicle satisfies a drum test condition.

[0065] In an optional embodiment, the drum test preprocessing device determines whether the vehicle satisfies the drum test condition by determining whether a hybrid control unit (HCU) of the vehicle is normal. In the case where the HCU is normal, the drum test preprocessing device determines that the vehicle satisfies the drum test condition. In the case where the HCU is abnormal, the drum test preprocessing device determines that the vehicle does not satisfy the drum test condition. The HCU being normal includes that a parameter value carried by a signal sent by the HCU is within a preset range. The HCU being abnormal includes that the parameter value carried by the signal sent by the HCU is outside the preset range.

[0066] In specific embodiments, the drum test preprocessing device determines whether the HCU is normal according to the signal sent by the HCU. The signal sent by the HCU includes at least one of a vehicle speed signal, a wheel speed signal, and a brake pressure signal. Correspondingly, the drum test preprocessing device determining whether the HCU is normal according to the signal sent by the HCU includes at least one of the following: the drum test preprocessing device determining whether the vehicle speed carried by the vehicle speed signal sent by the HCU is within a preset vehicle speed range; the drum test preprocessing device determining whether the wheel speed carried by the wheel speed signal sent by the HCU is within a preset wheel speed range; and the drum test preprocessing device determining whether the brake pressure carried by the brake pressure signal sent by the HCU is within a preset pressure range.

[0067] The following describes a scheme for the drum test preprocessing device to determine whether the HCU is normal in three embodiments.

[0068] First embodiment: The signal sent by the HCU includes a vehicle speed signal, and the drum test preprocessing device determines whether the HCU is normal according to the vehicle speed carried by the vehicle speed signal sent by the HCU.

[0069] In specific embodiments, the drum test preprocessing device determines whether the vehicle speed carried by the vehicle speed signal sent by the HCU is within a preset vehicle speed range. In the case where the vehicle speed carried by the vehicle speed signal sent by the HCU is outside the preset vehicle speed range, the drum test preprocessing device determines that the HCU is abnormal.

[0070] In specific embodiments, the drum test preprocessing device determines whether the vehicle speed carried by the vehicle speed signal sent by the HCU is greater than or equal to the lower limit of the preset vehicle speed range and less than or equal to the upper limit of the preset vehicle speed range. In the case where the vehicle speed carried by the vehicle speed signal is greater than or equal to the lower limit of the preset vehicle speed range and less than or equal to the upper limit of the preset vehicle speed range, the drum test preprocessing device determines that the vehicle speed carried by the vehicle speed signal is within the preset vehicle speed range. In the case where the vehicle speed carried by the vehicle speed signal is less than the lower limit of the preset vehicle speed range or greater than the upper limit of the preset vehicle speed range, the drum test preprocessing device determines that the vehicle speed carried by the vehicle speed signal is outside the preset vehicle speed range.

[0073] In a specific embodiment, the drum test preprocessing device determines whether the wheel speed carried by the wheel speed signal sent by the HCU is greater than or equal to the lower limit of the preset wheel speed range and less than or equal to the upper limit of the preset wheel speed range. In the case where the wheel speed carried by the wheel speed signal is greater than or equal to the lower limit of the preset wheel speed range and less than or equal to the upper limit of the preset wheel speed range, the drum test preprocessing device determines that the wheel speed carried by the wheel speed signal is within the preset wheel speed range. In the case where the wheel speed carried by the wheel speed signal is less than the lower limit of the preset wheel speed range or greater than the upper limit of the preset wheel speed range, the drum test preprocessing device determines that the wheel speed carried by the wheel speed signal is outside the preset wheel speed range.

[0074] A third embodiment: the signal sent by the HCU includes a brake pressure signal, and the drum test preprocessing device determines whether the HCU is normal according to the brake pressure carried by the brake pressure signal sent by the HCU.

[0075] In a specific embodiment, the drum test preprocessing device determines whether the brake pressure carried by the brake pressure signal sent by the HCU is within a preset brake pressure range. In the case where the brake pressure carried by the brake pressure signal sent by the HCU is outside the preset brake pressure range, the drum test preprocessing device determines that the HCU is abnormal.

[0076] In a specific embodiment, the drum test preprocessing device determines whether the brake pressure carried by the brake pressure signal sent by the HCU is greater than or equal to the lower limit of the preset brake pressure range and less than or equal to the upper limit of the preset brake pressure range. In the case where the brake pressure carried by the brake pressure signal is greater than or equal to the lower limit of the preset brake pressure range and less than or equal to the upper limit of the preset brake pressure range, the drum test preprocessing device determines that the brake pressure carried by the brake pressure signal is within the preset brake pressure range. In the case where the brake pressure carried by the brake pressure signal is less than the lower limit of the preset brake pressure range or greater than the upper limit of the preset brake pressure range, the drum test preprocessing device determines that the brake pressure carried by the brake pressure signal is outside the preset brake pressure range.

[0077] It should be noted that the above three embodiments of determining whether the HCU is normal can be independently implemented or combined, and the embodiments of the present application do not limit this.

[0078] S103. Inhibiting the brake system of the vehicle from alarming in the case that the vehicle meets the drum test condition.

[0079] The brake system of the vehicle comprises at least one of an antilock brake system (ABS) and an electronic brake system (EBS).

[0080] The drum test preprocessing device prohibits the braking system of the vehicle from alarming in the case that the vehicle meets the drum test condition, so as to avoid that the braking system of the vehicle alarms during the drum test of the vehicle, and the accuracy of the drum test is affected. Optionally, the drum test preprocessing device prohibits the braking system of the vehicle from alarming for a preset time length, or the drum test preprocessing device prohibits the braking system of the vehicle from alarming in a preset time period. The preset time length is greater than a time length required for the drum test of the vehicle, and the preset time period includes a time period for the drum test of the vehicle.

[0081] In a specific embodiment, in the case that the vehicle meets the drum test condition, the drum test preprocessing device sends alarm prohibition information to the braking system of the vehicle, the alarm prohibition information is used to instruct the braking system to prohibit alarming, and the braking system prohibits the braking system from alarming according to the alarm prohibition information.

[0082] The alarm prohibition information and the implementation of the braking system of the vehicle prohibiting the braking system from alarming according to the alarm prohibition information are introduced in the following three embodiments.

[0083] First embodiment: The alarm prohibition information includes alarm prohibition indication information and a preset time length, the alarm prohibition indication information is used to instruct to prohibit alarming, and the alarm prohibition information is used to instruct to prohibit alarming for the preset time length. After the braking system of the vehicle receives the alarm prohibition information, the braking system determines to prohibit alarming according to the alarm prohibition indication information, and the braking system determines to prohibit alarming for the preset time length according to the alarm prohibition information. The braking system prohibits the braking system from alarming for the preset time length from the time when the braking system receives the alarm prohibition information. For example, the braking system determines a prohibition time period according to the alarm prohibition information, the starting time of the prohibition time period is the time when the braking system receives the alarm prohibition information, the time length of the prohibition time period is equal to the preset time length, and the braking system prohibits the braking system from alarming in the prohibition time period.

[0084] Second embodiment: The alarm prohibition information includes alarm prohibition indication information and a preset time period, the alarm prohibition indication information is used to instruct to prohibit alarming, and the alarm prohibition information is used to instruct to prohibit alarming in the preset time period. After the braking system of the vehicle receives the alarm prohibition information, the braking system determines to prohibit alarming according to the alarm prohibition indication information, and the braking system determines to prohibit alarming in the preset time period according to the alarm prohibition information. The braking system prohibits the braking system from alarming in the preset time period according to the alarm prohibition information.

[0085] A third embodiment: the alarm prohibition information is alarm prohibition indication information, the alarm prohibition information is used to indicate that the alarm is prohibited, after the braking system of the vehicle receives the alarm prohibition information, the braking system determines that the alarm is prohibited according to the alarm prohibition information, and then the braking system prohibits the braking system from alarming according to the alarm prohibition information.

[0086] In an optional embodiment, after the braking system of the vehicle is prohibited from alarming, the vehicle can be subjected to a drum test. For the first embodiment described above, the braking system prohibits the braking system from alarming for a preset time period, and after the preset time period, the braking system cancels the prohibition of alarming; since the preset time period is longer than the time period required for the drum test of the vehicle, the drum test of the vehicle can be completed within the time period during which the braking system prohibits the braking system from alarming, thereby avoiding the alarming of the braking system during the drum test of the vehicle. For the second embodiment described above, the braking system prohibits the braking system from alarming for a preset time period, and after the preset time period, the braking system cancels the prohibition of alarming; since the preset time period includes the time period for the drum test of the vehicle, the drum test of the vehicle can be completed within the time period during which the braking system prohibits the braking system from alarming, thereby avoiding the alarming of the braking system during the drum test of the vehicle. For the third embodiment described above, after the drum test of the vehicle is completed, the drum test preprocessing device can send alarm cancellation information to the braking system of the vehicle, so that the braking system cancels the prohibition of alarming of the braking system according to the alarm cancellation information.

[0087] In an optional embodiment, when the vehicle meets the drum test condition, the drum test preprocessing device outputs first prompt information, and the first prompt information is used to indicate that the vehicle meets the drum test condition. After the drum test preprocessing device outputs the first prompt information, the user can trigger a determination instruction based on the first prompt information. The drum test preprocessing device receives the determination instruction, and the drum test preprocessing device prohibits the braking system of the vehicle from alarming according to the determination instruction. In a specific embodiment, the drum test preprocessing device controls the touch display component of the vehicle to display the first prompt information, or the drum test preprocessing device controls the voice interaction component of the vehicle to play the first prompt information, and the present application is not limited in this regard. In one embodiment, when the vehicle meets the drum test condition, the drum test preprocessing device controls the touch display component of the vehicle to display a display interface including the first prompt information, and the user triggers a determination instruction based on the first prompt information in the display interface. As an example, as shown in FIG. 8, when the vehicle meets the drum test condition, the drum test preprocessing device controls the touch display component of the vehicle to display a display interface including the first prompt information. Figure 4As shown in FIG. 6, which shows a schematic diagram of a display interface of an embodiment of the present application, the display interface displays a prompt information box A1, a confirm button and a cancel button. The prompt information box A1 includes first prompt information "satisfy the drum test condition". The user can click the confirm button to trigger a confirm instruction for drum test, and the drum test preprocessing device disables the alarm of the braking system of the vehicle according to the confirm instruction. Alternatively, the user can click the cancel button to trigger a cancel instruction for drum test, and the drum test preprocessing device closes the prompt information box A1 and cancels the drum test according to the cancel instruction.

[0088] The above embodiments are described taking the case that the vehicle satisfies the drum test condition. In the case that the vehicle does not satisfy the drum test condition, the drum test preprocessing device can output second prompt information for indicating that the vehicle does not satisfy the drum test condition. In specific embodiments, the drum test preprocessing device controls the touch display assembly of the vehicle to display the second prompt information, or the drum test preprocessing device controls the voice interaction assembly of the vehicle to play the second prompt information, which is not limited in the embodiments of the present application. In one embodiment, in the case that the vehicle does not satisfy the drum test condition, the drum test preprocessing device controls the touch display assembly of the vehicle to display a display interface including the second prompt information. As an example, as shown in FIG. 7, which shows a schematic diagram of another display interface of an embodiment of the present application, the display interface displays a prompt information box A2 and a close button. The prompt information box A2 includes second prompt information "do not satisfy the drum test condition". The user can click the close button to close the prompt information box A2. Figure 5

[0089] S104. After disabling the alarm of the braking system, activate the drum test to perform the drum test on the vehicle.

[0090] After disabling the alarm of the braking system of the vehicle, the drum test preprocessing device activates the drum test to perform the drum test on the vehicle. Thus, the alarm of the braking system of the vehicle can be avoided during the drum test on the vehicle. In optional embodiments, after disabling the alarm of the braking system of the vehicle, the drum test preprocessing device sends a drum test signal to the drum test platform to activate the drum test. The drum test platform performs the drum test on the vehicle after receiving the drum test signal.

[0091] In specific embodiments, Figure 6 FIG. 1 is a schematic diagram of a drum test platform carrying a vehicle according to an embodiment of the present application. As shown in FIG. 1, the drum test platform includes a drum test preprocessing device, a braking system, a touch display assembly and a voice interaction assembly. Figure 6 ​As shown, after the vehicle is located on the drum test platform, the drum test preprocessing device sends a drum test signal to the drum test platform to activate the drum test after prohibiting the brake system alarm of the vehicle, and the drum test platform performs the drum test on the vehicle after receiving the drum test signal.

[0092] In summary, the drum test preprocessing method provided by the embodiments of the present application is used to determine whether the vehicle meets the drum test condition by receiving the activation instruction for activating the drum test and responding to the activation instruction after the vehicle is carried to the drum test platform. In the case that the vehicle meets the drum test condition, the drum test preprocessing device prohibits the brake system alarm of the vehicle and activates the drum test to perform the drum test on the vehicle. Thus, the embodiments of the present application prohibit the brake system alarm of the vehicle before the drum test, avoid the energy recovery device of the vehicle from being unable to be activated due to the brake system alarm of the vehicle during the drum test, ensure that the energy recovery device of the vehicle can work normally during the drum test, and thus ensure the accuracy of the drum test.
