[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0046] Figure 1 A flowchart showing a vehicle wake-up test method provided by an embodiment of the present application is shown.
[0047] Reference Figure 1The vehicle wake-up test method of the embodiment of the application is applied to a battery sensor, and the vehicle wake-up test method comprises the following steps of:
[0048] S101, receiving a wake-up test instruction.
[0049] S102, according to the wake-up test instruction, issuing an abnormal wake-up signal to make the vehicle controller make a corresponding strategy according to the abnormal wake-up signal.
[0050] During the test, the battery sensor receives a wake-up test instruction, which is issued by a test module. After receiving the wake-up test instruction, the battery sensor no longer detects the actual power of the battery, but defaults that the test condition under the wake-up test instruction is true, and issues an abnormal wake-up signal to the vehicle controller to make the vehicle controller make a corresponding strategy according to the abnormal wake-up signal. The vehicle controller can be a body controller, a chassis controller or the like.
[0051] The battery sensor of the application adds the function of wake-up test, can support the vehicle to be quickly tested and woken up, and does not need to wait for the battery power to drop to the wake-up threshold, thereby meeting the vehicle wake-up test function and reducing the test duration and test difficulty.
[0052] In an embodiment, the wake-up test instruction is a first wake-up control instruction, the battery sensor issues a low-power wake-up instruction according to the first wake-up control instruction, and the first wake-up control instruction is a low-power wake-up control instruction.
[0053] In another embodiment, the wake-up test instruction is a second wake-up control instruction, the battery sensor issues an abnormal discharge wake-up instruction according to the second wake-up control instruction, and the second wake-up control instruction is an abnormal discharge wake-up instruction.
[0054] The first wake-up control instruction and the second wake-up control instruction are sent through a defined UDS (Unified Diagnostic Services) service. Of course, the wake-up test instruction is not limited to the two test module instructions, and other types of wake-up tests can also be designed according to requirements.
[0055] As shown in FIG. 1, before receiving the wake-up test instruction, the vehicle wake-up test method further comprises the following steps of: Figure 2
[0056] S201, receiving a diagnosis command.
[0057] S202, according to the diagnosis command, the battery sensor enters a wake-up test mode after the vehicle bus enters a sleep state.
[0058] When the vehicle is in the wake-up test, the vehicle controller sends a diagnosis command to the battery sensor, and after the battery sensor receives the diagnosis command, the battery sensor is switched from the standard test mode to the wake-up test mode when the vehicle bus enters the sleep state. At this time, the battery sensor performs steps S101 and S102. In the present application, the vehicle bus is a LIN bus, and the standard test mode is the self-test function of the battery sensor.
[0059] Further, the vehicle wake-up test method further comprises:
[0060] S203, when the vehicle completes the corresponding strategy, the vehicle bus enters the sleep state again, and the battery sensor jumps from the wake-up test mode to the standard test mode.
[0061] In the present application, when the vehicle completes the corresponding strategy, i.e. the vehicle completes the wake-up test, after the vehicle bus enters the sleep state again, the battery sensor jumps from the wake-up test mode to the standard test mode and continues the regular test function.
[0062] The present application adds a wake-up test function to the battery sensor, so that the battery sensor can automatically set the condition that can trigger the wake-up according to the wake-up condition, quickly wake up the vehicle and send the wake-up reason, so that the vehicle can implement the corresponding strategy according to the wake-up reason, thereby meeting the vehicle wake-up test function and reducing the test duration and test difficulty.
[0063] As shown in Figure 3 According to another aspect of the embodiment of the present application, a vehicle wake-up test device is provided, which is applied to a battery sensor and comprises:
[0064] The first receiving module 301 is configured to receive a wake-up test instruction.
[0065] The first processing module 302 is configured to send an abnormal wake-up signal according to the wake-up test instruction, so that the vehicle controller makes a corresponding strategy according to the abnormal wake-up signal.
[0066] During the test, the battery sensor receives a wake-up test instruction sent by a test module. After receiving the wake-up test instruction, the battery sensor no longer detects the actual power of the battery, but defaults the test condition under the wake-up test instruction as true, and sends an abnormal wake-up signal to the vehicle controller, so that the vehicle controller makes a corresponding strategy according to the abnormal wake-up signal. The vehicle controller can be a body controller, a chassis controller, etc.
[0067] The battery sensor of the application adds the function of the wake-up test, can support the vehicle to carry out the quick test wake-up, and does not need to wait for the battery power to drop to the wake-up threshold, thereby meeting the vehicle wake-up test function, reducing the test duration and test difficulty.
[0068] In an embodiment, the wake-up test instruction is a first wake-up control instruction, and the battery sensor sends a low-power wake-up instruction according to the first wake-up control instruction, and the first wake-up control instruction is a low-power wake-up control instruction.
[0069] In another embodiment, the wake-up test instruction is a second wake-up control instruction, and the battery sensor sends an abnormal discharge wake-up instruction according to the second wake-up control instruction, and the second wake-up control instruction is an abnormal discharge wake-up instruction.
[0070] The first wake-up control instruction and the second wake-up control instruction are sent through a defined UDS service. Of course, the wake-up test instruction is not limited to the two test module instructions, and can also be designed as other types of wake-up tests according to requirements.
[0071] Further, as shown in the vehicle wake-up test device also includes: Figure 4
[0072] The second receiving module 401 is used for receiving a diagnosis command.
[0073] The second processing module 402 is used for entering the wake-up test mode of the battery sensor after the vehicle bus enters the sleep state according to the diagnosis command.
[0074] When the vehicle carries out the wake-up test, the vehicle controller sends a diagnosis command to the battery sensor, and after the battery sensor receives the diagnosis command, when the vehicle bus enters the sleep state, the battery sensor is converted from the standard test mode to the wake-up test mode. In the application, the vehicle bus is a LIN bus, and the standard test mode is the self-test function of the battery sensor.
[0075] Further, the vehicle wake-up test device also includes:
[0076] The third processing module 403 is used for jumping the battery sensor from the wake-up test mode to the standard test mode after the vehicle bus enters the sleep state again after the vehicle completes the corresponding strategy.
[0077] In the application, when the vehicle completes the corresponding strategy, that is, the vehicle completes the wake-up test, after the vehicle bus enters the sleep state again, the battery sensor jumps from the wake-up test mode to the standard test mode, and continues to carry out the normal test function.
[0078] The vehicle wake-up test device provided by the embodiments of the present application can execute the vehicle wake-up test method provided by any of the embodiments of the present application, and has the function modules and beneficial effects corresponding to the execution method.

The vehicle controller 51 is configured to make a corresponding strategy according to the abnormal wake-up signal. In addition, the vehicle wake-up test system 500 further comprises a communication interface 54 and an input / output interface 55.
[0081] In the vehicle wake-up test system 500 of the present application, when the vehicle is performing a wake-up test, the vehicle controller 51 sends a diagnosis command to the battery sensor 52. After the battery sensor 52 receives the diagnosis command, when the vehicle bus enters a sleep state, the battery sensor 52 is switched from a standard test mode to a wake-up test mode.
[0082] During the test, the battery sensor 52 receives a wake-up test instruction sent by the test module 53. After receiving the wake-up test instruction, the battery sensor 52 no longer detects the actual power of the battery, but assumes that the test condition under the wake-up test instruction is true, and sends an abnormal wake-up signal to the vehicle controller 51, so that the vehicle controller 51 makes a corresponding strategy according to the abnormal wake-up signal.
[0083] In an embodiment, the wake-up test instruction is a first wake-up control instruction, and the battery sensor 52 sends a low-power wake-up instruction according to the first wake-up control instruction. In another embodiment, the wake-up test instruction is a second wake-up control instruction, and the battery sensor 52 sends an abnormal discharge wake-up instruction according to the second wake-up control instruction. The second wake-up control instruction is an abnormal discharge wake-up instruction.
[0084] When the vehicle completes the corresponding strategy, i.e., the vehicle completes the wake-up test, and the vehicle bus enters the sleep state again, the battery sensor 52 jumps from the wake-up test mode to the standard test mode and continues the normal test function.
[0085] This invention adds a wake-up test function to the battery sensor, enabling the battery sensor to automatically set conditions that can trigger wake-up based on wake-up conditions, quickly wake up the vehicle and send a wake-up reason, so that the vehicle can implement corresponding strategies based on the wake-up reason, thereby satisfying the vehicle wake-up test function and reducing test time and test difficulty.
