[0038] Reference Figure 1 , Figure 1 This is an optional flowchart of a power supply control method for a vehicle data storage system provided in an embodiment of the present application. The method may include but is not limited to steps S101 to S103:

[0039] Step S101, obtaining the current power supply status of the vehicle;

[0040] Step S102, determining a target power supply strategy based on the current power supply status of the vehicle;

[0041] Step S103 : Controlling the power supply of the vehicle data storage system according to the target power supply strategy.

[0042] In some embodiments, the vehicle data storage system, i.e., the in-vehicle data storage core, is used to store data information generated in the vehicle and support the remaining computing units to complete data storage tasks such as local data storage, local training, and remote data upload / download.

[0043] In some embodiments, step S101 may include but is not limited to steps S201 to S203:

[0044] Step S201, monitoring the instruction reception status and the current working status of the vehicle high voltage power supply system;

[0045] Step S202, when the instruction receiving state is receiving a preset target control instruction, determining the current power supply state of the vehicle as a low voltage power supply state;

[0046] Step S203 : When the current working state is that the vehicle high-voltage power supply system is in operation, the current power supply state of the vehicle is determined to be a high-voltage power supply state.

[0047] In step S202 of some embodiments, the target control instruction may include but is not limited to a vehicle remote wake-up instruction and a vehicle remote control instruction. When the current power supply state of the vehicle is a low-voltage power supply state, the vehicle data storage system is powered by the vehicle battery.

[0048] In step S102 of some embodiments, the power supply strategy includes a step-down power supply strategy and a supplementary power supply strategy. Specifically, when the current power supply state of the vehicle is a low-voltage power supply state, the target power supply strategy is determined to be a supplementary power supply strategy. When the current power supply state of the vehicle is a high-voltage power supply state, the target power supply strategy is determined to be a step-down power supply strategy.

[0049] In some embodiments, step S103 may include but is not limited to steps S301 to S302:

[0050] Step S301, when the target power supply strategy is the supplementary power supply strategy, the vehicle data storage system is powered by the vehicle low-voltage system, the current power of the vehicle low-voltage system is monitored, and based on the current power of the vehicle low-voltage system, it is determined whether to supplement the power supply of the vehicle low-voltage system by the vehicle high-voltage system;

[0051] Step S302 , when the target power supply strategy is the step-down power supply strategy, the high voltage output by the vehicle high voltage system is stepped down by the vehicle step-down system, and the stepped-down voltage is output, and the stepped-down voltage is used to power the vehicle data storage system.

[0052] In step S301 of some embodiments, since the exhaustion of the vehicle battery may cause the vehicle to be unable to start normally, seriously affecting the user experience, a supplementary power supply strategy is set to dynamically monitor the power value of the vehicle battery. When it is detected that the vehicle battery power is too low, the vehicle high-voltage system is started to charge the vehicle battery. Specifically, when the current power of the vehicle low-voltage system is less than a given power threshold, the vehicle low-voltage system is powered by the vehicle high-voltage system; otherwise, the vehicle low-voltage system is not powered by the vehicle high-voltage system.

[0053] In some embodiments, step S302 may include but is not limited to steps S401 to S402:

[0054] Step S401, obtaining a preset target output voltage;

[0055] In step S402 , the vehicle step-down system performs step-down processing on the high voltage outputted by the vehicle high voltage system according to the target output voltage, reduces the high voltage to the target output voltage, outputs the corresponding step-down voltage, and uses the step-down voltage to power the vehicle data storage system.

[0056] In some embodiments, an LDO (low dropout regulator) step-down system (such as the above-mentioned vehicle step-down system) is used to step down the high voltage voltage output by the vehicle's high-voltage system, reducing the high voltage to a step-down voltage corresponding to a target voltage threshold, and then using the step-down voltage to power the vehicle's data storage system.
