Description

Technical Field

[0001] The present invention generally relates to the field of automotive electronics, and more specifically, to a method for diagnosing abnormal wake-up faults of a vehicle, a diagnostic device, a diagnostic system, a computing device, a computer-readable storage medium, a computer program product, and a vehicle. Background Art

[0002] In recent years, with the increase in market demand, vehicle functions have gradually increased, and modern vehicles are gradually developing towards intelligence, electrification and networking. Many vehicles have on-board networking terminals such as T-BOX, which connect the on-board communication bus (such as CAN bus) and the external cloud server to achieve communication and data exchange between vehicles, vehicles and infrastructure, and vehicles and the Internet. At the same time, more and more electronic control units (ECUs) and associated sensors and actuators are installed on vehicles. When the ECUs are fully or partially awakened, these ECUs and associated sensors and actuators consume the power of the vehicle battery (12V battery).

[0003] When the vehicle is in a sleep state (such as when the engine is turned off and the vehicle is parked), usually all ECUs are also in a sleep state, and are only awakened by control commands (such as those received via the vehicle communication bus) in certain special cases. However, if an ECU fails and is awakened abnormally, the entire electronic and electrical system may be awakened, thereby quickly consuming the battery power of the vehicle. Since the vehicle is in a sleep state, the battery cannot be charged. In this case, if the abnormal wake-up lasts for a long time or is triggered frequently, the battery power will be completely depleted, which will cause the vehicle to be unable to start. In addition, there is no on-board record or off-board record (such as recorded by a cloud server) for abnormal wake-up failures, and it will be difficult for vehicle manufacturers to find the root cause of the abnormal wake-up failure and the resulting battery depletion. Summary of the invention

[0037] For the convenience of description, some terms appearing in the present invention are explained below. It should be understood that the terms used in this application should be interpreted as having the same meaning as in the context of this application specification and in the relevant field. The terms "include", "comprises" and similar terms in the present invention should be understood as open terms, i.e. "including but not limited to", indicating that other contents may also be included.

[0038] In an embodiment of the present invention, the term “based on” means “based at least in part on”.

[0039] In the embodiments of the present invention, the term "one embodiment" means "at least one embodiment".

[0040] In the embodiments of the present invention, the term "another embodiment" means "at least one additional embodiment" and the like.

[0041] In the embodiments of the present invention, the term "vehicle" may be a car, a truck, an SUV, a van, a bus, or any other rolling platform. The vehicle may be a pure electric vehicle or a hybrid vehicle.

[0042] In the embodiments of the present invention, the term "battery" may include a single battery, a battery module consisting of multiple batteries, or a battery pack.

[0043] Currently, when a vehicle is in sleep mode, if an ECU fails and wakes up abnormally, it may cause the entire electronic and electrical system to wake up, thereby quickly consuming the battery power of the vehicle. If the abnormal wake-up lasts for a long time or is triggered frequently, the battery power will be completely exhausted, which will cause the vehicle to be unable to start. In addition, there is no on-board or off-board record of the abnormal wake-up failure (such as recorded by a cloud server), and it will be difficult for vehicle manufacturers to find the root cause of the abnormal wake-up failure and the battery power exhaustion caused by it.

[0044] To this end, the present invention proposes a vehicle abnormal wake-up fault diagnosis method, diagnostic device, diagnostic system, computing equipment, computer-readable storage medium, computer program product and vehicle. In the scheme of the present invention, the abnormal wake-up fault that may exist in the electronic and electrical system can be diagnosed when the vehicle is asleep, so as to avoid the vehicle battery being exhausted and causing the vehicle to be unable to start, while extending the life of the battery. In addition, the scheme of the present invention can also record fault information for subsequent diagnosis, maintenance or updating of the electronic and electrical system, which is low-cost and easy to implement, and improves the user experience. The content of the present invention is explained below based on several embodiments.

[0045] First reference Figure 1 , Figure 1 A flow chart of an abnormal awakening fault diagnosis method according to an embodiment of the present invention is shown. The abnormal awakening fault diagnosis method can be executed by any computing device on a vehicle, for example, by a body controller unit (BCM) of the vehicle.

[0046] In step 101, when the vehicle is in a sleep state, it is determined whether the electronic and electrical system of the vehicle has an abnormal wake-up failure based on a light detection signal from at least one light sensing device. The number of at least one light sensing device can be one or more, which are arranged in the cabin of the vehicle and detect the bright light in the cabin. When a certain ECU is awakened and the entire electronic and electrical system is awakened, some indicator lights, instrument panels and / or central display screens in the vehicle cabin will light up, so the light sensing device can be used to detect the bright light in the vehicle cabin, that is, to detect whether the indicator lights, instrument panels and / or central display screens in the vehicle cabin emit bright light. In a preferred embodiment, the light sensing device can be arranged close to the instrument panel and / or central display screen to avoid the influence of ambient light outside the cabin on the detection signal. The light sensing device can be any type of light sensing device. In a preferred embodiment, the light sensing device is a passive light sensing device (such as including a photosensitive element), which does not consume battery power, thereby further saving energy consumption.

[0047] In some embodiments, Figure 2 The method shown is used to determine whether there is an abnormal wake-up fault in the vehicle's electronic and electrical system. Figure 2 Shows Figure 1 An exemplary flowchart of step 101 in an embodiment of the present invention.

[0048] In step 201, a light detection signal is obtained. The light detection signal may be received from a light sensing device.

[0049] In step 202, it is determined whether the electronic and electrical system is awakened based on the light detection signal. It is possible to continuously detect whether the light detection signal jumps. When it is detected that the light detection signal jumps, it is determined whether the amplitude of the jump exceeds a first preset threshold set for the light detection signal. If the amplitude of the jump exceeds the first preset threshold, it means that the bright light in the cabin of the vehicle suddenly increases to a certain amplitude, and then it can be determined that the electronic and electrical system is awakened.

[0050] In step 203, in response to the electronic and electrical system being awakened, it is determined whether the awakening is an abnormal awakening. Since the electronic and electrical system may be awakened normally, such as when the vehicle user sends a remote control command, the vehicle's in-vehicle networking device (such as T-BOX) or other systems are remotely upgraded (such as OTA), and a specific ECU needs to process data periodically, after determining that the electronic and electrical system is awakened, it is also necessary to determine whether the awakening is an abnormal awakening.

[0051] In some embodiments, in step 203, it can be determined whether the wake-up is an abnormal wake-up in the following manner. First, determine whether the vehicle has received a remote control command and whether a remote upgrade is being performed. The remote control command can be sent by the vehicle user to the vehicle's in-vehicle networking device via an application (app) on a smartphone, for example, and can include remote vehicle unlocking, remote vehicle locking, remote engine start, remote air conditioning start, remote light on, remote alarm, etc. It can be determined whether the vehicle has received a remote control command by communicating with the in-vehicle networking device. In addition, it is also possible to communicate with the vehicle's in-vehicle networking device and infotainment system to determine whether the vehicle has received a software upgrade package from the cloud server and performed a remote upgrade. If the vehicle receives a remote control command and / or is performing a remote upgrade, it is determined that the vehicle's wake-up is a normal wake-up. On the contrary, if the vehicle does not receive a remote control command and is not performing a remote upgrade, it is determined that the vehicle's wake-up is an abnormal wake-up.

[0052] In step 204, in response to the awakening being an abnormal awakening, it is determined that an abnormal awakening fault exists in the electronic and electrical system. After the awakening is determined to be an abnormal awakening, it can be determined that an abnormal awakening fault exists in the electronic and electrical system.

[0053] In some embodiments, Figure 3 The method shown is used to determine whether there is an abnormal wake-up fault in the vehicle's electronic and electrical system. Figure 3 Shows Figure 1Another exemplary flowchart of step 101 in an embodiment of the present invention.

[0054] In step 301, an activation signal for indicating that the electronic and electrical system is awakened is obtained. The activation signal is generated based on the amplitude of the jump of the light detection signal exceeding the first preset threshold. For example, the light sensing device can continuously detect whether the light detection signal jumps. When the light detection signal jumps, it is determined whether the amplitude of the jump exceeds the first preset threshold set for the light detection signal. If the amplitude of the jump exceeds the first preset threshold, it means that the bright light in the cabin of the vehicle suddenly increases to a certain amplitude, then it can be determined that the electronic and electrical system is awakened, and the light sensing device generates an activation signal for indicating that the electronic and electrical system is awakened. The computing device (such as BCM) executing method 100 receives the activation signal from the light sensing device and is activated under the action of the activation signal. Before receiving the activation signal, the computing device executing method 100 is in sleep mode and does not consume the power of the 12V battery, so energy consumption can be further saved.

[0055] In step 302, in response to the activation signal, it is determined whether the wake-up is an abnormal wake-up. Since there may be a situation where the electronic and electrical system is awakened normally, such as the vehicle user sends a remote control command, the vehicle's onboard networking equipment (TBOX) or other systems are remotely upgraded (OTA), and a specific ECU needs to process data periodically, after determining that the electronic and electrical system is awakened, it is also necessary to determine whether the wake-up is an abnormal wake-up. The specific steps for determining whether the wake-up is an abnormal wake-up can refer to the description of step 203 above, which will not be repeated here.

[0056] In step 303, in response to the awakening being abnormal awakening, it is determined that an abnormal awakening fault exists in the electronic and electrical system. After the awakening is determined to be abnormal awakening, it can be determined that an abnormal awakening fault exists in the electronic and electrical system.

[0057] Continue to refer Figure 1 In step 102, in response to the existence of an abnormal wake-up fault in the electronic and electrical system, fault information is obtained. After determining that the electronic and electrical system has an abnormal wake-up fault, the fault information needs to be collected for subsequent fault diagnosis, system upgrades, and / or sending alarms or prompt messages to users.

[0058] In some embodiments, the fault information includes a list of electronic control units in an awake state and diagnostic results. The list of electronic control units in an awake state and the diagnostic results can be obtained in the following manner. First, a self-diagnosis command is sent to one or more electronic control units (ECUs) of the electronic and electrical system. The self-diagnosis command can be sent via an on-board communication bus (such as a CAN bus). Next, the diagnostic results from the electronic control units in the awake state are obtained, and a list of electronic control units in the awake state is generated.

[0059] In some embodiments, the fault information includes a battery status and / or a status warning message of a battery of the vehicle. The battery status and / or the status warning message of the battery can be obtained in the following manner. First, the battery status and / or the status warning message from the battery sensing device is obtained. The battery status includes at least one of the real-time voltage, real-time current and remaining power of the battery. The status warning message is generated based on the battery status, for example, when the real-time current exceeds a second preset threshold value.

[0060] In step 103, the fault information is sent via the vehicle's onboard networking device for fault diagnosis. The fault information can be sent to a cloud server for storage. The vehicle manufacturer can perform fault diagnosis, system maintenance, updates or upgrades and / or send alarms or prompt messages to users based on the fault information.

[0061] In the above embodiment, the abnormal awakening fault of the electronic and electrical system that may exist can be diagnosed when the vehicle is asleep, so as to avoid the vehicle battery being exhausted and causing the vehicle to be unable to start, and at the same time extend the battery life. In addition, the solution of the present invention can also record fault information for subsequent diagnosis, maintenance or update of the electronic and electrical system, which is low-cost and easy to implement, and improves the user experience.

[0062] Reference below Figure 4 An exemplary abnormal wakeup fault diagnosis system of the present invention is described. Figure 4 The diagram shows an architecture diagram of an abnormal wakeup fault diagnosis system according to an embodiment of the present invention.

[0063] exist Figure 4 In the embodiment of FIG. 4 , the abnormal awakening fault diagnosis system 400 includes a light sensing device 401, a battery sensing device 402, a body control module (BCM) 403, a T-BOX 404, an infotainment system 405, and a cloud server 406. Figure 4 As shown in the figure, the cloud server 406 communicates with the user's mobile phone and T-BOX 404 through a cellular network (such as 3G, 4G or 5G); the optical sensor device 401 communicates with the BCM 403 through a wired signal; the battery sensor device 402 communicates with the BCM 403 through the LIN bus; the BCM 403 communicates with the T-BOX 404 and the infotainment system 405 through the CAN bus; and the T-BOX 404 communicates with the infotainment system 405 through Ethernet. It should be noted that the communication method in this embodiment is only an example. In other embodiments, the above-mentioned components or modules may also adopt other communication methods.

[0064] The optical sensing device 401 is arranged in the cockpit of the vehicle, detects the bright light in the cockpit and generates an optical detection signal. When the optical detection signal jumps, the optical sensing device 401 determines whether the amplitude of the jump exceeds a first preset threshold. If the amplitude of the jump exceeds the first preset threshold, the optical sensing device 401 generates an activation signal for indicating that the electronic and electrical system is awakened, and sends it to the BCM 403 via the wired network. The BCM 403 is activated by the activation signal, and communicates with the T-BOX 404 and the infotainment system 405 to determine whether the vehicle has received a remote control command from the user's mobile phone and whether a remote upgrade is being performed. If the vehicle does not receive a remote control command and does not perform a remote upgrade, the BCM 403 determines that the vehicle's wake-up is an abnormal wake-up, and further determines that there is an abnormal wake-up fault in the electronic and electrical system. Afterwards, the BCM 403 sends a signal to all ECUs ( Figure 4 After the awakened ECU performs self-diagnosis, it sends the diagnosis result to BCM 403. BCM 403 generates a list of awakened ECUs according to the communication status with the ECUs.

[0065] In addition, the battery sensing device 402 can detect the battery status of the battery in real time, including real-time voltage, real-time current and / or remaining power, and generate a status warning message when the real-time current exceeds a second preset threshold. The second preset threshold is, for example, the current value of the battery when the vehicle is in a sleep state. The status warning message is, for example, "abnormal wakeup" or "the vehicle cannot enter a sleep state." The battery sensing device 402 sends the detected battery status and status warning message to the BCM 403 via the LIN bus. Then, the BCM 403 sends the diagnostic results of the ECU, the list of ECUs in the awakened state, the battery status, and the status warning message to the T-BOX 404 via the CAN bus, and the T-BOX 404 sends it to the cloud server 406 via the cellular network for storage and fault diagnosis.

[0066] In other embodiments, the battery sensing device 402 may only detect the battery status of the storage battery without generating and sending a status warning message. Alternatively, the battery sensing device 402 may only send a status warning message.

[0067] The present invention also proposes an abnormal awakening fault diagnosis device.
