Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to an automobile power distribution method, a power distribution system and an automobile. Background Art

[0002] At present, the power distribution of the whole vehicle is mainly based on the traditional combination of fuses and relays under the development model of the distributed electrical architecture of fuel vehicles. Each module mainly works in the following four power modes, namely OFF, ACC, ON and START. The body control module is connected to various wake-up sources to manage the power mode of the whole vehicle. In the combination scenario, such as the sentinel mode of the whole vehicle, non-related functional modules such as EPS controllers will also be awakened by power distribution, which makes it difficult to meet the requirements of energy management, scalability and multi-scenario combination under the new architecture of new energy vehicles.

[0003] In order to solve the above problems, semiconductor power devices and chips can be used to replace traditional fuses and relays, and the electrical architecture of the regional power distribution module and the central control unit can be customized according to the vehicle model architecture, so that the vehicle's sleep and wake-up power management will be managed by the regional power distribution module. The power status of the vehicle can be monitored in real time as needed, and it has the advantage of multi-scenario combination. For example, in the vehicle sentry mode, only one of the regional power distribution modules needs to wake up the relevant functional modules. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a vehicle power distribution method, a power distribution system and a vehicle, which can target the automotive intelligent power distribution sleep and wake-up function, comprehensively consider the current and subsequent function expansion scenario requirements, and rationally plan the design of each zone control software and hardware platform to achieve the sleep and wake-up function requirements of regional power distribution in different scenario modes.

[0005] The present invention provides an automobile power distribution method, which is applied to a smart car. The method comprises the following steps:

[0006] S100: When at least one zone-controlled power distribution module receives a wake-up signal from at least one wake-up source, it generates corresponding wake-up data according to the wake-up signal and sends the wake-up data to a central control unit; the wake-up data at least includes associated scene mode data or load data.

[0007] S200: The central control unit sends a corresponding power distribution instruction to the zone control power distribution module according to the current wake-up data to realize associated scene mode wake-up or load wake-up.

[0008] In the above technical solution, different from the traditional architecture vehicle model where the wake-up source is connected to the body control module and the power management is performed after the body control module wakes up, the present invention proposes that the wake-up source of the vehicle is no longer uniformly connected to the body control module, but the wake-up source is reserved and combined according to the principle of proximity of the wiring harness. It can be allocated to both the zone control unit and the normal power module, and is no longer limited to the limited wake-up source and 4 power modes of a single body control module. It greatly expands the wake-up source types of the whole vehicle and the power distribution application scenarios of the whole vehicle. At the same time, it can meet the on-demand power distribution needs of subsequent models in multiple scenarios according to different wake-up sources through iterative upgrades of software and hardware.

[0009] Further, the step S100 at least includes:

[0010] S111: When at least one zone-controlled power distribution module receives a wake-up signal for waking up any one or more of the zone-controlled power distribution modules, the wake-up signal triggers the regional control unit of the current zone-controlled power distribution module to operate;

[0011] S112: The regional control unit generates the associated scene mode data according to the wake-up signal, and sends the wake-up data to the central control unit.

[0012] Furthermore, the step S100 further includes:

[0013] S121: When at least one zone-controlled power distribution module receives a wake-up signal for waking up any one or more loads in the current zone-controlled power distribution module, the wake-up signal triggers the operation of the normal power module connected to the load.

[0014] S122: The bypass current of the permanent power module increases and sends an electrical signal to the regional control unit where the permanent power module is located.

[0015] S123: The regional control unit detects whether the bypass current exceeds a preset threshold value. If so, it triggers waking up the normal power supply and disconnecting the bypass power supply. Otherwise, it returns to S123.

[0016] S124: The regional control unit generates the load data according to the wake-up signal, and sends the load data to the central control unit.

[0017] In the above technical solution, the wake-up source can be assigned to either the zone control unit or the normal power module. The load with the wake-up source is configured with the normal power module and a monitorable bypass power supply. In low power consumption mode, the load is powered by the bypass power supply. When the zone control unit detects whether the bypass current exceeds the preset threshold, the bypass power supply is disconnected and powered by the normal power supply. The bypass power supply of the load can be turned on and off by the zone control unit. Therefore, the normal power module with the wake-up source reserved can disconnect the normal power supply under low power consumption, thereby reducing the number of modules working under low power consumption, and configuring the power supply to be turned on in subsequent software iteration upgrades.

[0018] Further, the step S200 specifically includes:

[0019] S211: After receiving the wake-up data from the regional control unit, the central control unit obtains a power distribution instruction corresponding to the wake-up data through calculation according to a built-in scene logic algorithm, and sends the power distribution instruction to the regional control unit.

[0020] S212: Each regional control unit controls the corresponding load power supply according to the received power distribution instruction to realize associated scene mode wake-up or load wake-up.

[0021] Furthermore, the scene logic algorithm specifically includes:

[0022] Receive the wake-up data as a target attribute parameter, and obtain the corresponding original attribute parameter in the current scene mode. When the target attribute parameter is different from the original attribute parameter, generate an associated scene mode of the current scene mode according to the target attribute parameter, and control entry into the associated scene mode to use the associated scene mode as a new current scene mode.

[0023] Furthermore, the associated scenario modes include at least: remote update mode, sentry mode, pet care mode, normal driving mode, automatic driving mode, hotel mode and cinema mode.

[0024] In the above technical solution, after the central control unit receives the wake-up data from each zone control, it calculates according to the built-in scenario algorithm logic and issues corresponding power distribution instructions to each zone control. Each zone control controls the power supply of the corresponding load according to the received power distribution instructions. For example, when the vehicle is in sentry mode, the vehicle receives the right door vibration data sent by the right door module of the right zone control. At this time, the central control unit will issue a power distribution instruction to the TBOX power distribution wake-up of the front zone control and send the vehicle anti-theft data to the driver for reminder.

[0025] As another preferred embodiment, the present invention further provides an automotive power distribution system, the system at least comprising:

[0026] A power distribution management system is used to generate corresponding wake-up data according to the wake-up signal when at least one zone-controlled power distribution module receives a wake-up signal from at least one wake-up source of the wake-up system, and send the wake-up data to a central control unit; the wake-up data at least includes associated scene mode data or load data.

[0027] The central control unit is used to issue corresponding power distribution instructions to the zone control power distribution module according to the current wake-up data to realize associated scene mode wake-up or load wake-up.

[0028] The wake-up system at least includes a plurality of wake-up sources connected to the regional control units and the loads in a one-to-one correspondence.

[0029] Furthermore, the power distribution management system includes at least a number of zone-controlled power distribution modules defined according to the vehicle model architecture design.

[0030] Furthermore, the zone-controlled power distribution module includes at least: a regional control unit, a plurality of loads, a plurality of normal power modules connected one-to-one with the loads, a bypass power supply connected to the normal power modules, and a normal power supply connected to the normal power modules and the loads.

[0031] As another preferred embodiment, the present invention also provides an automobile, comprising a plurality of zone-controlled power distribution modules arranged in the automobile, and a computer-readable storage medium communicatively connected to the zone-controlled power distribution modules, wherein a computer program is stored on the computer-readable storage medium; the computer program is controlled and executed by one or more processors to implement the automobile power distribution method as described above.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The present invention defines the zone control power distribution module according to the vehicle model architecture design, reserves resources and allocates the wake-up source in combination according to the principle of proximity of the wiring harness, and can be allocated to the zone control unit or the normal power module. It is no longer limited to the limited wake-up sources and 4 power modes of the body control module, greatly expanding the wake-up source types of the whole vehicle and the power distribution application scenarios of the whole vehicle. At the same time, it can meet the on-demand power distribution requirements according to different wake-up sources in multiple scenarios of subsequent vehicle models through iterative upgrades of software and hardware. At the same time, a normal power module is configured for the load with a wake-up source, and a monitorable bypass power supply is configured. In low power consumption mode, the load is powered by the bypass power supply. When the regional control unit detects whether the bypass current exceeds a preset threshold, the bypass power supply is disconnected and powered by the normal power supply, wherein the bypass power supply of the load can be turned on and off by the regional control unit. Therefore, the normal power module with the reserved wake-up source can disconnect the normal power supply under low power consumption, thereby reducing the number of modules working under low power consumption, and configuring the conduction power supply in subsequent software iteration upgrades.

[0041] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0042] Please refer to Figure 1 The present invention provides a vehicle power distribution method, which is applied to a smart car, and the method comprises the following steps:

[0043] S100: When at least one zone-controlled power distribution module receives a wake-up signal from at least one wake-up source, it generates corresponding wake-up data according to the wake-up signal and sends the wake-up data to a central control unit; the wake-up data at least includes associated scene mode data or load data.

[0044] S200: The central control unit sends a corresponding power distribution instruction to the zone control power distribution module according to the current wake-up data to realize associated scene mode wake-up or load wake-up.

[0045] Among them, different from the traditional architecture vehicle model, the wake-up source is connected to the body control module, and the power management is performed after the body control module wakes up. The present invention proposes that the wake-up source of the vehicle is no longer uniformly connected to the body control module, but the wake-up source is reserved and combined according to the principle of proximity of the wiring harness. It can be allocated to both the zone control unit and the normal power module, and is no longer limited to the limited wake-up source and 4 power modes of a single body control module. It greatly expands the wake-up source types of the whole vehicle and expands the power distribution application scenarios of the whole vehicle. At the same time, it can meet the on-demand power distribution needs of subsequent models in multiple scenarios according to different wake-up sources through iterative upgrades of software and hardware.

[0046] Please refer to Figures 2 to 3 For example, the whole vehicle is divided into four zone control and power distribution modules, namely front zone control, rear zone control, left zone control and right zone control. The loads in the front zone control include TBOX and central computing platform; the loads in the rear zone control include NFC and electric tailgate module; the loads in the left zone control include UWB, DCM-L, left front door module and left front door module; the loads in the right zone control include charging module, DCM-R, right front door module and EPB electronic parking controller.

[0047] During the specific implementation process, the number of zone control modules is defined according to the vehicle model architecture design, and is not limited to 4 zone control modules, including hardware wake-up source control unit wake-up source, normal power module wake-up source, normal power module, including but not limited to 3 modules, and secondary power distribution load, including but not limited to 2 loads.

[0048] In this embodiment, the step S100 at least includes:

[0049] S111: When at least one zone-controlled power distribution module receives a wake-up signal for waking up any one or more of the zone-controlled power distribution modules, the wake-up signal triggers the regional control unit of the current zone-controlled power distribution module to operate;

[0050] S112: The regional control unit generates the associated scene mode data according to the wake-up signal, and sends the wake-up data to the central control unit.

[0051] In this embodiment, the step S100 further includes:

[0052] S121: When at least one zone-controlled power distribution module receives a wake-up signal for waking up any one or more loads in the current zone-controlled power distribution module, the wake-up signal triggers the operation of the normal power module connected to the load.

[0053] S122: The bypass current of the permanent power module increases and sends an electrical signal to the regional control unit where the permanent power module is located.

[0054] S123: The regional control unit detects whether the bypass current exceeds a preset threshold value. If so, it triggers waking up the normal power supply and disconnecting the bypass power supply. Otherwise, it returns to S123.

[0055] S124: The regional control unit generates the load data according to the wake-up signal, and sends the load data to the central control unit.

[0056] During the specific implementation process, the wake-up source can be assigned to the zone control unit or to the normal power module. The load with the wake-up source is configured with the normal power module and a monitorable bypass power supply. In low power consumption mode, the load is powered by the bypass power supply. When the zone control unit detects whether the bypass current exceeds the preset threshold, the bypass power supply is disconnected and powered by the normal power supply. The bypass power supply of the load can be turned on and off by the zone control unit. Therefore, the normal power module with the wake-up source reserved can disconnect the normal power supply under low power consumption, reduce the number of modules working under low power consumption, and configure the power supply in subsequent software iteration upgrades.

[0057] Please refer to Figure 4 For example, each load is connected to a normal power module, and each normal power module is connected to a bypass power supply and a normal power supply, wherein after the wake-up source 1 triggers the regional control unit to wake up, the regional control unit distributes power to the central control unit after waking up, and the wake-up source type is transmitted to the central control unit; after the wake-up source 2 triggers the normal power module 2 to wake up, the bypass current of module 2 will increase, and a signal will be sent to the regional control unit at the same time. After the regional control unit detects that the corresponding bypass power supply current exceeds the threshold, it will trigger the wake-up, turn on the normal power supply of module 1, and disconnect the bypass low-power power supply of module 1. The regional control unit distributes power to the central control unit and transmits the signal type of the wake-up source 2 to the central control unit.

[0058] It should be understood that the bypass power supply is connected to the normal power supply inside the regional control unit.

[0059] Among them, the regional control unit is connected to the central control unit for transmitting wake-up data and power distribution instructions; the normal power module is connected to the Smart mosfet for detecting whether the corresponding bypass power supply current exceeds the threshold.

[0060] In this embodiment, the step S200 specifically includes:

[0061] S211: After receiving the wake-up data from the regional control unit, the central control unit obtains a power distribution instruction corresponding to the wake-up data through calculation according to a built-in scene logic algorithm, and sends the power distribution instruction to the regional control unit.

[0062] S212: Each regional control unit controls the corresponding load power supply according to the received power distribution instruction to realize associated scene mode wake-up or load wake-up.

[0063] In this embodiment, the scene logic algorithm specifically includes:

[0064] Receive the wake-up data as a target attribute parameter, and obtain the corresponding original attribute parameter in the current scene mode. When the target attribute parameter is different from the original attribute parameter, generate an associated scene mode of the current scene mode according to the target attribute parameter, and control entry into the associated scene mode to use the associated scene mode as a new current scene mode.

[0065] In this embodiment, the associated scene modes include at least: remote update mode, sentry mode, pet care mode, normal driving mode, automatic driving mode, hotel mode and cinema mode.

[0066] Please refer to Figure 5 For example, after receiving the wake-up data from each zone control, the central control unit calculates according to the built-in scene algorithm logic and issues a corresponding power distribution instruction to each zone control. Each zone control controls the corresponding load power supply according to the received power distribution instruction, for example:

[0067] Scenario Example 1

[0068] When the vehicle is in sentry mode, the vehicle receives the right door vibration data sent by the right door module of the right zone control. At this time, the central control unit will issue a power distribution command to the TBOX power distribution wake-up of the front zone control and send the vehicle anti-theft data to the driver for reminder.

[0069] Scenario Example 2

[0070] When the vehicle is in pet care mode, the vehicle receives a signal from the front zone air conditioning module that the interior temperature exceeds the threshold. At this time, the central control unit will issue a power distribution command to wake up the air conditioning-related modules, such as the front and rear zone blower loads and the air conditioning compressor, to cool the internal pet.

[0071] Scenario Example 3

[0072] The vehicle is in camping mode, and the vehicle receives a signal from the external power module detected by the rear area. At this time, the central control unit sends a power distribution command to the chassis power distribution module under the control of the rear area, and the power distribution wakes up. The vehicle controls the external discharge of the battery to the external power module.

[0073] Please refer to Figure 6 and Figure 4 As another preferred embodiment, the present invention further provides an automotive power distribution system, the system at least comprising:

[0074] A power distribution management system is used to generate corresponding wake-up data according to the wake-up signal when at least one zone-controlled power distribution module receives a wake-up signal from at least one wake-up source of the wake-up system, and send the wake-up data to a central control unit; the wake-up data at least includes associated scene mode data or load data.

[0079] For example, please refer to Figure 7 In a preferred embodiment, it includes a wake-up detection system for each zone control, a power distribution scene determination of the central control unit, and a power distribution management system for each zone control. The wake-up detection system for each zone control includes the wake-up source of each regional module itself and the unit module of the power distribution, the power distribution management system for each zone control includes the direct power distribution management of each zone control to its load, and the power distribution scene determination of the central control unit is mainly based on the logical determination of the wake-up source.
