Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0039] In order to improve the problem that the current vehicle power supply system does not protect the fuse related to passenger safety, when the vehicle collides, it is very easy to cause the fuse related to passenger safety to be damaged, affecting external rescue and passenger escape, and increasing the passenger casualty rate and secondary accident rate. The disclosed embodiments provide a vehicle power supply system, a vehicle power supply control method, a device and an electronic device.

[0040] like Figure 1As shown, an embodiment of the present disclosure provides a vehicle power supply system, which includes: an in-cabin fuse box 1, a battery 2 and a power control module 3; the in-cabin fuse box 1 is connected to the battery 2 through a first circuit, and the in-cabin fuse box 1 is used to store and protect fuses with functions related to passenger safety, wherein the first circuit is a circuit for connecting the in-cabin fuse box 1 and the battery 2, and the battery 2 may include but is not limited to a lead-acid battery, a lithium battery, etc., and passenger safety-related functions may include but are not limited to door unlocking, emergency calls and other rescue and passenger escape functions, and the in-cabin fuse box 1 and the battery 2 are arranged in a collision safety area, and the collision safety area is an area where no extrusion deformation will occur during a vehicle collision. By adjusting the power supply fuse position related to key functions such as passenger safety to the collision safety area, the function loss caused by the damage of the fuse during the collision is avoided, and the passenger casualty rate and the secondary accident rate are reduced. As a possible implementation method, collision simulation analysis can be used. The collision safety area is determined by analysis, that is, the collision safety area can be finally determined by performing various collision conditions analysis on the simulation vehicle model, wherein the collision conditions may include but are not limited to front collision, side collision, rear-end collision, rollover, etc. of the simulation vehicle model; the first end of the power control module 3 is connected to the battery 2, and the second end of the power control module 3 is connected to the second circuit. The power control module 3 is used to obtain the current value of the second circuit, and when the current value is greater than the preset current value, the connection between the second circuit and the battery 2 is disconnected, so that the battery 2 is not affected by the current value and can continue to supply power to the fuse box 1 in the cabin. The preset current value is the maximum current value that the power control module 3 can withstand. The second circuit is a circuit in which a device outside the fuse box 1 in the cabin is connected to the battery 2. By adding the power control module 3, the failure of the vehicle power system caused by the short circuit that may exist in the collision is avoided, resulting in the failure of key functions such as collision safety, so that the battery 2 is not affected by the current value and can continue to supply power to the fuse box 1 in the cabin.

[0041] In specific application scenarios, such as Figure 3 As shown, the power control module 3 also includes at least one of a main fuse 31 and a current monitoring module 32; the main fuse 31 is used to cut off the connection between the second circuit and the battery 2 when the current value is greater than the preset working current value, so that the battery 2 is not affected by the current value and can continue to supply power to the fuse box 1 in the cabin, and the preset working current value is a current value greater than the normal working current range; the current monitoring module 32 is used to obtain the current value in the second circuit, and when the current value is greater than the preset working current value, the connection between the second circuit and the battery is cut off, so that the battery is not affected by the current value and can continue to supply power to the fuse box in the cabin. For the embodiments of the present disclosure, Figure 2As shown, in order to prevent other components of the power supply system (devices other than the in-cabin fuse box 1) from being damaged or short-circuited in the event of a collision, which would affect the battery, causing the circuit of the vehicle battery 2 to short-circuit, lowering the voltage of the battery 2, and causing the battery 2 to be unable to normally supply power to the in-cabin fuse box 1, a power control module 3 is added to the second circuit between the other components of the power supply system (devices other than the in-cabin fuse box 1) and the battery 2. In the event of a short circuit in the second circuit between the other components of the power supply system and the battery 2, the current will increase instantaneously. When the preset working current value is reached, the power control module 3 will cut off the connection between the second circuit and the battery 2, so that the battery 2 is not affected by the current value and can continue to provide working voltage to the in-cabin fuse box 1.

[0042] In specific application scenarios, such as Figure 1 and 2 As shown, the vehicle power supply system also includes: a power generation device 6; the power generation device 6 is connected to the battery 2 through the power control module 3, and the power generation device 6 is used to supply power to the battery 2, so that the battery 2 can always supply power to the fuse box 1 in the cabin. The power generation device 6 may include but is not limited to a generator, an on-board transformer unit, etc., wherein the generator is suitable for fuel vehicles, and the on-board transformer unit is suitable for electric vehicles. The on-board transformer unit can convert high-voltage power into low-voltage power and supply power to on-board electrical appliances.

[0043] In specific application scenarios, such as Figure 1 and 2 As shown, the vehicle power supply system also includes: a cabin fuse box 5 and / or a cabin fuse box 4; the cabin fuse box 5 is connected to a power generation device 6, and the cabin fuse box 5 is used to store and protect fuses of electrical appliances inside the cabin, wherein the electrical appliances inside the cabin may include but are not limited to in-vehicle electrical appliances such as window lifts, electric seats, and airbags, and the power generation device 6 is used to supply power to the cabin fuse box 5; the cabin fuse box 4 is connected to the power generation device 6 via a B1 circuit, and the cabin fuse box 4 is used to store and protect fuses of electrical appliances outside the vehicle, wherein the electrical appliances outside the vehicle may include but are not limited to electronic controller units, lights, horns, anti-lock braking systems, etc., and the power generation device 6 is also used to supply power to the cabin fuse box 4. Figure 2 As shown, the cabin fuse box 4 is also connected to the battery 2 through the B2 circuit and the power control module 3. The battery 2 is used to supply power to the cabin fuse box 4 when the vehicle collides, the power supply circuit of the power generation equipment 6 fails, and the functions in the cabin fuse box 4 can still be used, so that the corresponding functions of the cabin fuse box 4 can be used normally.

[0044] For the embodiment of the present disclosure, since different electrical equipment in the cabin fuse box 4 have different power consumption paths, which may include but are not limited to obtaining the power of the power generation equipment 6 through the B1 circuit, or obtaining the power of the battery 2 through the B2 circuit, by directly connecting the cabin fuse box 4 and the battery 2 to the B2 circuit, the circuit line length is reduced, saving economic costs.

[0045] In a specific application scenario, the storage battery 2 may include but is not limited to a lithium battery; when the power control module 3 cuts off the connection between the cabin fuse box 4 and the lithium battery, the power-off time point of the lithium battery is later than the power control module 3 cut-off time point. For the embodiment of the present disclosure, when the working current value of the lithium battery in the external power supply exceeds the preset working current value of the lithium battery itself, and the time when the working current passes through the lithium battery is greater than the preset current flow time of the lithium battery, the lithium battery will automatically cut off the power, and the preset current flow time is the longest time that the lithium battery can accept the working current flow. In order to prevent the lithium battery from automatically cutting off the power, resulting in the inability to supply power to the cabin fuse box 1 normally, it is necessary to ensure that the power-off time point of the lithium battery is later than the cut-off time point of the power control module 3. Exemplarily, when the working current value is 300-400A, the disconnection time of the power control module 3 is 4s, so it is necessary to ensure that when the working current value of the lithium battery is 300-400A, the preset current flow time is greater than 4 seconds, that is, the power-off time point of the lithium battery is later than the cut-off time point of the power control module 3, so that the lithium battery will not be automatically powered off.

[0046] like Figure 4 As shown, an embodiment of the present disclosure provides a vehicle power supply control method, which can be applied to the above-mentioned vehicle power supply system and executed by a power supply control module in the vehicle power supply system, wherein the vehicle power supply control method may include:

[0047] Step 101: Obtain a current value of a second circuit.

[0048] The second circuit is a circuit in which components other than the fuse box in the cabin are connected to the battery.

[0049] For the disclosed embodiment, before obtaining the current value of the second circuit, it is necessary to arrange the battery and the fuse box in the cabin in the collision safety area. The collision safety area is an area where no extrusion deformation will occur during the vehicle collision. The battery is used to provide current to the on-board electrical appliances, wherein the battery may include but is not limited to a lead-acid battery, a lithium battery, etc., wherein if the battery is a lead-acid battery, the lead-acid battery can always supply power to the on-board electrical appliances until the power control module is disconnected, and then the power supply to the cabin fuse box is stopped; if the battery is a lithium battery, when the working current value of the lithium battery in the external power supply exceeds the preset working current value of the lithium battery itself, and the time when the working current passes through the lithium battery is greater than the preset current flow time of the lithium battery, the lithium battery will automatically cut off the power, and the preset current flow time is the longest time that the working current can accept for the lithium battery. In order to prevent the lithium battery from automatically cutting off the power, resulting in the inability to supply power to the fuse box in the cabin normally, it is necessary to ensure that the power-off time point of the lithium battery is later than the cut-off time point of the power control module. Exemplarily, when the working current value is 300-400A, the disconnection time of the power control module is 4s, so it is necessary to ensure that when the working current value of the lithium battery is 300-400A, the preset current flows for more than 4 seconds, so as not to cause the lithium battery to be powered off. The on-board electrical appliances may include but are not limited to the cabin fuse box and the cabin fuse box, etc. The cabin fuse box is used to store and protect the fuses of the external electrical appliances of the vehicle, wherein the external electrical appliances of the vehicle may include but are not limited to the electronic controller unit, the lights, the horn, the anti-lock braking system, etc. The cabin fuse box is used to store and protect the fuses of the functions related to passenger safety, and the fuses of the functions related to passenger safety can be protected, so that when the vehicle collides, the fuses of the functions related to passenger safety are not easily damaged, wherein the functions related to passenger safety may include but are not limited to the rescue and passenger escape functions such as door unlocking and emergency calls. As a possible implementation method, collision simulation analysis can be used to determine the collision safety area, that is, the collision safety area can be ultimately determined by performing various collision condition analyses on the simulated vehicle model, wherein the collision conditions may include but are not limited to frontal collision, side collision, rear-end collision, rollover, etc. of the simulated vehicle model.

[0050] In the embodiment of the present disclosure, the executing entity may be a power control module, which obtains the current value of the circuit connecting the other components of the power supply system except the in-cabin fuse box and the battery through the power control module. When other components of the power supply system are damaged or short-circuited, that is, when the current value is greater than the maximum current value that the power control module can withstand, the connection between the other components except the in-cabin fuse box and the second circuit of the battery can be disconnected, so that the battery is not affected by the current value and can continue to supply power to the in-cabin fuse box, thereby ensuring the normal operation of functions related to passenger safety, thereby reducing the passenger casualty rate and the occurrence rate of secondary accidents.

[0051] Step 102: Compare the current value with a preset current value.

[0052] The preset current value is the maximum current value that the power control module can withstand.

[0053] For the embodiment of the present disclosure, the current value is used to indicate the magnitude of the current value generated by the connection between the first circuit and the battery, and the magnitude of the current value generated by the connection between the second circuit and the battery, wherein the first circuit is a circuit for connecting the fuse box in the cabin and the battery, the preset current value is the maximum current value that the power control module can withstand, the power control module compares the current value with the preset current value, and controls the battery to normally supply power to the fuse box in the cabin according to the comparison result. Wherein, the power control module may include but is not limited to a total fuse and a current monitoring module, if the power control module is a total fuse, in the case of a short circuit between the second circuit and the battery, the current will increase instantly, when the maximum current value that the total fuse can withstand is reached, the total fuse will melt, and the battery can normally provide the working voltage for the fuse box in the cabin; if the power control module is a current monitoring module, in the case of a short circuit between the second circuit and the battery, the current will increase instantly, when the current value exceeds the preset working current value, the current monitoring module will disconnect the second circuit, and the battery can normally provide the working voltage for the fuse box in the cabin, and the preset working current value is a current value greater than the normal working current range.

[0054] Step 103: When the current value is greater than the preset current value, disconnect the second circuit from the battery so that the battery is not affected by the current value and can continue to supply power to the fuse box in the cabin.

[0055] With respect to the disclosed embodiment, in the event of an extreme collision of the vehicle, a short circuit may occur in the circuits (second circuit) of other components of the power supply system, causing the current value received by the battery to be greater than a preset current value. In order to prevent the voltage of the battery from being lowered in the event of a short circuit, resulting in the battery being unable to normally supply power to the in-cabin fuse box. Therefore, a power control module is added to the second circuit between the other components of the power supply system (devices other than the in-cabin fuse box) and the battery. The power control module can disconnect the battery when the current value is greater than the preset current value, so that the battery can normally supply power to the in-cabin fuse box, thereby reducing the passenger casualty rate and the occurrence rate of secondary accidents.

[0056] As another possible implementation method, when the vehicle is in a minor collision or no collision occurs, the current value received by the battery is less than or equal to the preset current value. The power control module does not need to disconnect from the battery, and the battery can supply power to the fuse box in the cabin normally.

[0057] In summary, according to the vehicle power supply control method provided by the present invention, compared with the current existing technology, the present invention can connect the in-cabin fuse box with the battery through a first circuit, the in-cabin fuse box is used to store and protect fuses with functions related to passenger safety, and arrange the in-cabin fuse box and the battery in a collision safety area, which is an area that will not be squeezed and deformed during a vehicle collision; the first end of the power control module is connected to the battery, and the second end of the power control module is connected to the second circuit; the power control module is used to obtain the current value of the second circuit, and when the current value is greater than a preset current value, disconnect the second circuit from the battery, so that the battery is not affected by the current value and can continue to supply power to the in-cabin fuse box, the preset current value is the maximum current value that the power control module can withstand, and the second circuit is a circuit that connects components other than the in-cabin fuse box with the battery. In the disclosed solution, since the fuses for functions related to passenger safety are stored in the in-cabin fuse box, and the in-cabin fuse box and the battery are arranged in the collision safety area, the fuses related to passenger safety are doubly protected, so that when a collision occurs in the vehicle, the fuses related to passenger safety are not easily damaged; the current value of the second circuit connecting other components of the power supply system with the battery is obtained through the power control module. After a collision, if other components of the power supply system are damaged or short-circuited, the connection between the second circuit and the battery can be disconnected, so that the battery is not affected by the current value and can continue to supply power to the in-cabin fuse box, thereby ensuring the normal operation of functions related to passenger safety, and reducing the passenger casualty rate and the secondary accident rate.

[0058] Based on the above Figure 4 The specific implementation of the method shown in the embodiment provides a vehicle power supply control device, such as Figure 5 As shown, the device includes: an acquisition module 41, a comparison module 42 and a control module 43;

[0059] An acquisition module 41, which can be used to acquire the current value of the second circuit;

[0060] A comparison module 42, which can be used to compare the current value with a preset current value, where the preset current value is the maximum current value that the power control module can withstand;

[0061] The control module 43 can be used to disconnect the second circuit from the battery when the current value is greater than a preset current value, so that the battery is not affected by the current value and can continue to supply power to the fuse box in the cabin.

[0070] Through the description of the above implementation methods, the technicians in this field can clearly understand that the present application can be implemented by means of software plus necessary general hardware platforms, or by hardware. By applying the scheme of this embodiment, compared with the current prior art, the present disclosure can connect the cabin fuse box with the battery through the first circuit, the cabin fuse box is used to store and protect the fuses with functions related to passenger safety, and arrange the cabin fuse box and the battery in the collision safety area, which is the area where no extrusion deformation will occur during the vehicle collision; the first end of the power control module is connected to the battery, and the second end of the power control module is connected to the second circuit; the power control module is used to obtain the current value of the second circuit, and when the current value is greater than the preset current value, disconnect the second circuit from the battery, so that the battery is not affected by the current value and can continue to supply power to the cabin fuse box, the preset current value is the maximum current value that the power control module can withstand, and the second circuit is a circuit that connects the components other than the cabin fuse box with the battery. In the disclosed solution, since the fuses for functions related to passenger safety are stored in the in-cabin fuse box, and the in-cabin fuse box and the battery are arranged in the collision safety area, the fuses related to passenger safety are doubly protected, so that when a collision occurs in the vehicle, the fuses related to passenger safety are not easily damaged; the current value of the second circuit connecting other components of the power supply system with the battery is obtained through the power control module. After a collision, if other components of the power supply system are damaged or short-circuited, the connection between the second circuit and the battery can be disconnected, so that the battery is not affected by the current value and can continue to supply power to the in-cabin fuse box, thereby ensuring the normal operation of functions related to passenger safety, and reducing the passenger casualty rate and the secondary accident rate.
