Description

Vehicle load power distribution control method, device and computer program product TECHNICAL FIELD

[0001] The present disclosure relates to the field of automotive electronics, in particular to a vehicle load power distribution control method, device and computer program product. BACKGROUND

[0002] With the development of automotive intelligent power distribution technology, power semiconductor devices such as High-Side Driver (HSD) and Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) gradually replace traditional fuses to realize power distribution control of vehicle load subsystems. The above-mentioned devices are widely used in modern automotive electronic systems due to their fast response speed and high control accuracy.

[0003] However, during vehicle driving, the load subsystems may encounter occasional abnormal current surges or short circuit conditions, which may cause the power semiconductor devices of the intelligent power distribution port to shut down, thereby affecting the normal operation of the vehicle functions. For example, the headlamps may affect night driving safety after power failure. Currently, when facing such problems, the intelligent power distribution unit on the market usually needs to be parked and powered on and off again to clear the fault code state and restore power supply, which not only brings inconvenience to users, but also may affect driving safety to some extent.

[0004] Although some vehicle models adopt a software restart strategy, i.e. setting an automatic retry mechanism with a certain time interval after the power device is hard shut down, in order to realize the automatic restart of the hardware. However, the vehicle software restart logic is usually fixed, and the above-mentioned method may not be suitable for all hardware restart conditions, especially when the abnormal current surge has large variability, the fixed restart strategy may fail to restart the hardware successfully, resulting in function failure.

[0005] Therefore, the prior art has obvious deficiencies in dealing with the problem of hardware shutdown of power semiconductor devices in intelligent power distribution units caused by abnormal current surges, and there is an urgent need for a more flexible and reliable solution to improve user experience and ensure driving safety.

[0021] If the abnormal current value generated by the load does not exceed the hardware shutdown limit value of the power semiconductor device of the power distribution unit of the load, the power distribution unit of the load sends a fault signal and the abnormal current value of the load to the logic operation unit; when the logic operation unit determines that the abnormal current value exceeds the value set by the software logical arbitration, the logic operation unit sends a power-off request signal to the power distribution unit of the load, and the power distribution unit of the load shuts down the power distribution port of the load according to the power-off request signal.

[0045] The following description of the embodiments is with reference to the drawings, which are used to illustrate specific embodiments that the present disclosure can be used to implement.

[0046] Referring to Fig. 1, an embodiment of the present disclosure provides a vehicle load power distribution control method, comprising the following steps:

[0047] When a fault of a load of the vehicle is monitored, automatically shutting down a power distribution port of a power distribution unit of the load;

[0048] Identifying whether there is a state jump triggered by a driver's operation on a vehicle bus communication network;

[0049] When the state jump is identified, sending a power-on request to the power distribution unit of the load to restore the load power distribution.

[0050] As can be seen from the above steps, the present disclosure can automatically detect the fault condition of the load of the vehicle without stopping the vehicle, and automatically shut down the power distribution port when the load fails. At the same time, the state jump triggered by the driver's usual operation is intelligently identified and the load power supply is restored, which not only improves the reliability and safety of the vehicle system, but also improves the user experience, thereby reducing the inconvenience and potential driving risks caused by the failure of the load.

[0051] Specifically, please combine Figure 2, in the embodiment of the present disclosure, the load is a certain load device or system in the vehicle intelligent power distribution system, which is powered by the power distribution unit. Abnormalities may occur during use, such as generating an abnormal large current impact, thereby triggering the intelligent protection mechanism of the power distribution unit. Power semiconductor devices are key elements in the power distribution unit for realizing power conversion and control, used to monitor and control the current of the load, and shut down the power distribution port to protect the system when an anomaly is detected.

[0052] Taking a certain load of a vehicle (collectively referred to as X load) as an example, during use of the vehicle (such as the driver unlocking and getting on the vehicle, stopping on the roadside, or driving), the X load itself or the harness circuit has an abnormality (such as the X load system generating an abnormal large current impact, i.e. a low probability incident), causing the intelligent power distribution port of the power distribution unit (such as the zone control unit (ZCU) / body control module (BCM)) for the X load to shut down. According to the specific fault condition, the shutdown type of the intelligent power distribution port can be divided into hardware shutdown and software shutdown:

[0053] As shown in Figure 3, when the abnormal current value generated by the X load exceeds the hardware shutdown limit value of the power semiconductor device of the power distribution unit, the power semiconductor device will directly shut down and send a fault signal to the logic operation unit / microcontroller (MCU); the logic operation unit / MCU records the fault signal of the X load.

[0054] As shown in Figure 4, if the power distribution unit of the X load identifies that the power distribution port of the X load does not meet the hardware shutdown condition according to the fault condition, it sends a fault signal and an abnormal current value of the X load to the logic operation unit / MCU; when the logic operation unit / MCU judges that the abnormal current value exceeds the value set by the software logic arbitration, it sends a power-down request signal to the power distribution unit of the X load, and the power distribution unit of the X load shuts down the power distribution port of the X load accordingly.

[0055] In the above hardware shutdown or software shutdown cases, the power supply to the X load will be interrupted, resulting in a failure of its function. Therefore, a mechanism is needed to detect when to attempt to restore power without affecting driving safety and experience. Compared with the prior art which requires the vehicle to be parked and then powered on again to restore power to the power semiconductor device of the power distribution port, the embodiment of the present disclosure provides a self-recovery power distribution mechanism that does not require the vehicle to be parked and is not noticeable to the driver.

[0056] The trigger condition of the self-recovery power distribution mechanism is the driver's regular operation, such as stepping on the brake pedal or turning the turn signal handle. Since the above operation frequently occurs during vehicle driving and is naturally integrated into driving behavior, it does not interfere with the normal operation of the driver as a trigger condition.

[0057] Whether the driver discovers that the X load has failed, when the driver steps on the brake pedal, the accelerator pedal, or turns the turn signal handle, that is, intentionally or unintentionally decelerates or changes lanes during driving, the relevant state signal value on the vehicle bus communication network will jump (that is, switch from one state to another state): (1) the brake pedal state signal value will jump (indicating that the driver steps on or releases the brake pedal); or (2) the accelerator pedal state signal value will jump (indicating that the driver steps on or releases the accelerator pedal); or (3) the turn signal state signal value jumps any state (indicating that the driver turns left or right).

[0058] When the logic operation unit / MCU identifies any of the above state jumps, it sends an X load power-on request to the power distribution unit, instructing it to try to power the X load again. After receiving the power-on request, the power distribution unit will try to reopen the power semiconductor device of the X load power distribution port. If the abnormal current surge of the load is an occasional abnormal failure, the recovery power distribution process is performed; if the abnormal current surge of the load is not an occasional abnormal failure, the power distribution port of the load is triggered again. Specifically, if the abnormal current surge of the X load is an occasional low-probability abnormal failure, the X load will regain power distribution at this time, that is, the recovery function, and in the above process, the driver will hardly realize that his or her usual operation has completed the power-on restart of the X load, thereby achieving "unaware recovery".

[0059] However, if the abnormal current surge of the X load is not an occasional low-probability abnormal failure, but a short circuit or persistent overload, although the aforementioned "unaware recovery" is performed, the abnormal current of the short circuit or overload still exists, and the short circuit or overload condition will trigger the power distribution port of the X load to be closed again. Please refer to FIG. 5 again. For the above case, the embodiment of the present disclosure sets a retry strategy, that is, the aforementioned unaware recovery process (that is, identifying that the vehicle bus communication network has a state jump triggered based on the driver's operation, triggering the logic operation unit / MCU to send a power-on request to the power distribution unit of the X load) is retried n times to try to open the power distribution port of the X load. After n cycles of retry, if the X load power distribution port still cannot be successfully opened (that is, the short circuit or overload condition still exists), it indicates that the X load is indeed in a serious failure state, and in order to protect the hardware from further damage, the power distribution port of the X load is no longer tried to be opened.
