Description

Technical Field

[0001] This application relates to the field of autonomous driving technology, and in particular to a method for controlling a vehicle-mounted multi-channel power switch and a vehicle-mounted power supply box. Background Art

[0002] Under the increasing demand for intelligent sensing peripheral kits in autonomous driving vehicles, when different sensor peripherals such as lidar, millimeter-wave radar, cameras, domain controllers, etc. in the autonomous driving kit work together, they need to meet a certain power-on and power-off timing sequence. Some peripheral kits even need to rely on other kits to power on before they can work.

[0003] In the related art, the vehicle-mounted power supply box mainly provides multiple channels of DC power output, and the multiple channels of DC power are in the state of being turned on and off simultaneously. However, at the transient of the output power on and off, the vehicle-mounted battery bears a huge impact current. In addition, in terms of monitoring the power supply timing sequence of peripheral devices, the vehicle-mounted device mainly realizes it through the main controller bus command and the auxiliary electronic switch. Some peripheral kits are even in a long-term waiting and energy-consuming state before officially entering the working state. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0042] The inventor found during research that the main purpose of the vehicle-mounted power supply box in the related art is to replace traditional relays and fuses, and at the same time add intelligent port protection, implementation status monitoring, and fault diagnosis functions.

[0043] Meanwhile, the in-vehicle device depends on the communication bus and the auxiliary electronic switch for the start-up priority control timing of the peripheral kit. On the power supply end side, there is no autonomous control timing relationship established between the output power paths, and each power output path highly depends on the scheduling and switching of the in-vehicle main controller.

[0044] In view of the above deficiencies, in the in-vehicle multi-channel power switch control method in the embodiments of the present application, by adding a start-stop timing control module inside the in-vehicle intelligent power box, the multi-channel power is autonomously controlled in terms of timing and priority according to the order and priority configured by the user online, and there is no need for an external controller to intervene in the scheduling, thereby meeting the power supply timing requirements of various autonomous driving kits, improving the power supply efficiency of the power box, and to a certain extent, improving the in-vehicle battery life and the safety of in-vehicle devices.

[0045] The following will, with reference to the accompanying drawings, elaborate on the technical solutions provided by the embodiments of the present application in detail.

[0046] As Figure 1 shown, the internal structure of the output power start-stop timing control module of the in-vehicle power box includes a CAN communication module, a main control of the in-vehicle power box, a configuration storage module, multi-channel power control, and a power channel. Among them, the CAN communication module is used as an interface for configuring the power output channel, and the user transmits and configures parameters through this interface. The main control of the in-vehicle power box is used to receive the configuration data of the CAN communication module, access the configuration parameters of the power output channel in the configuration module, and control the opening and closing of the multi-channel power according to the configuration parameters. The configuration storage module is used to store the configuration parameters for the user to close the power channel, and the configuration parameters can be loaded or overwritten at any time. The multi-channel power control is used to receive control instructions and output and close the power path. The power channel is used as a physical interface for supplying power to external devices.

[0047] The embodiments of the present application provide a method for controlling an in-vehicle multi-channel power switch. As Figure 2 shown, the flowchart in the embodiments of the present application is provided. The in-vehicle multi-channel power switch control method at least includes the following steps S210 to step S220:

[0048] Step S210, the in-vehicle power box is powered on and starts, and the configuration parameters of each power output channel are loaded, where the configuration parameters at least include one of the following: priority level. The priority level includes a start-up priority level.

[0049] After being powered on and starting, the in-vehicle power box will load the configuration parameters of each power output channel after starting. It should be noted that the configuration parameters of each power output channel are pre-configured. If there is no pre-configuration, the default configuration parameters will be loaded for the initialization configuration process.

[0050] Furthermore, the configuration parameters include, but are not limited to, priority level, delay time, output power parameters, and switch control status.

[0051] In some embodiments, if the user has not set the configuration parameters through the CAN bus, the system default configuration parameters are loaded at startup. It can be understood that the default configuration parameters can be a feasible default parameter with the priority order according to the power output channel number sequence.

[0052] Step S220: Traverse and configure the configuration parameters in the power output channels in sequence according to the startup priority level to perform startup control on the power output channels.

[0053] Since the startup priority level is included in the priority level, the startup priority level traverses and configures the configuration parameters in the power output channels in sequence. That is to say, after the configuration parameters are loaded, the power output channels to be configured are traversed in the priority order (startup priority level). When one or more output channels are defaulted to the off state, there is no need to configure them, and they can be directly skipped to the next power output channel.

[0054] It should be noted that the power channels with relatively higher priority can be preferentially controlled at startup.

[0055] It can be understood that for the power output channels, there are only two different states: startup or shutdown, that is, providing power or not providing power. The state of the switch is defaulted to off or on. For the intelligent sensing peripheral kit for autonomous driving, different sensor peripherals such as lidar, millimeter-wave radar, cameras, domain controllers, etc. have different control requirements for power. Through the above configuration optimization method, the timing and priority of multiple power supplies can be autonomously controlled, and there is no need for an external controller to intervene in scheduling, so as to meet the power supply timing requirements of various autonomous driving kits and improve the power supply efficiency of the power box.

[0056] The configuration parameters further include at least one of the following: delay time, output power parameters, and switch control status.

[0057] In an embodiment of the present application, the priority level includes a shutdown priority level, and the method further includes: when the vehicle-mounted power box enters the sleep state or receives an instruction to shut down multiple power output channels, traversing and configuring the configuration parameters in the power output channels in sequence according to the shutdown priority level to perform shutdown control on the power output channels.

[0058] During specific implementation, in addition to starting the control of the power output channels, it is also necessary to perform shutdown control on the power output channels. When the vehicle-mounted power supply box enters the sleep state (certain power output channels need to be turned off) or receives an instruction to turn off multiple power output channels, the configuration parameters in the power output channels are traversed and configured in sequence according to the shutdown priority level, thereby realizing the shutdown control of the power output channels.

[0059] It should be noted that when the power channel with a relatively higher priority is turned off, it can be controlled preferentially.

[0060] In an embodiment of the present application, the configuration parameters in the power output channels traversed and configured by the start priority level are the same as the configuration parameters in the power output channels traversed and configured by the shutdown priority level.

[0061] During specific implementation, that is, the start or shutdown timing control of the power channels can adopt the same configuration parameters. The configuration parameters in the power output channels traversed and configured by the start priority level are used to control the opening of multiple power channels. And the configuration parameters in the power output channels traversed and configured by the shutdown priority level are used to control the shutdown of multiple power channels.

[0062] In an embodiment of the present application, it further includes configuring two sets of different configuration parameters for the configuration parameters in the power output channels traversed and configured by the start priority level or the shutdown priority level.

[0063] During specific implementation, two sets of configuration parameters can be set, one for the start timing of the power channels and one for the shutdown timing of the power channels. By configuring two sets of different configuration parameters, different timings are realized. One set is for the configuration parameters in the power output channels traversed and configured by the start priority level. The other set can be for the configuration parameters in the power output channels traversed and configured by the shutdown priority level.

[0064] In an embodiment of the present application, the method further includes: switching from the current power output channel to the next power output channel according to the delay time.

[0065] During specific implementation, the delay time is the cumulative time starting from the end of the configuration of the previous channel, that is, the interval time between the start and stop of adjacent power channels. Switch from the current power output channel to the next power output channel according to the delay time.

[0066] It should be noted that if there is no current channel, it will jump to the next channel.

[0067] In an embodiment of the present application, the switch control state includes off and on, and the default state is on. Sequentially traversing and configuring the configuration parameters in the power output channels according to the startup priority level to perform startup control on the power output channels includes: sequentially traversing and configuring the switch control state in the configuration parameters of the current power output channel as on according to the startup priority level to perform startup control on the current power output channel; sequentially traversing and configuring the switch control state in the configuration parameters of the current power output channel as off according to the startup priority level to perform startup control on the current power output channel.

[0068] In specific implementation, for the multiple power output channels in the power supply box, sequentially traversing and configuring the switch control state in the configuration parameters of the current power output channel as on according to the startup priority level realizes startup control on the current power output channel. Similarly, sequentially traversing and configuring the switch control state in the configuration parameters of the current power output channel as off according to the startup priority level realizes startup control on the current power output channel. When controlling on or off, the startup priority level and the shutdown priority level can be the same or different.

[0069] In an embodiment of the present application, the output power parameters at least include output voltage and output current. Sequentially traversing and configuring the configuration parameters in the power output channels according to the startup priority level to perform startup control on the power output channels includes: sequentially traversing and configuring the output voltage, the output current, and the switch control state in the configuration parameters of each power output channel according to the startup priority level to perform startup control on the power output channels.

[0070] In specific implementation, since the output power parameters at least include output voltage and output current, sequentially traversing and configuring the output voltage, the output current, and the switch control state in the configuration parameters of each power output channel according to the startup priority level, thereby performing startup control on the power output channels. Similarly, the shutdown control will not be elaborated here.

[0071] In an embodiment of the present application, the method further includes: detecting whether the priority level in the configuration parameters of each power output channel is valid. The detecting step includes: setting memories numbered from 1 to N, and all initializing the stored value to 0. The memories numbered from 1 to N correspond to the power channels numbered from 1 to N; traversing the priority values of the power channels from 1 to N once, and setting the stored value of the memory corresponding to the priority value to 1; checking whether there is a memory with a stored value of 0 in the memories from 1 to N; if there is, the priority level configuration data is incorrect, and the detection is stopped; if not, the priority level configuration data meets the requirements.

[0072] During specific implementation, by detecting whether the priority level in the configuration parameters of each power output channel is valid, it can effectively verify whether the user's set parameters are correct.

[0073] First, set memories numbered from 1 to N, and all initializing the stored value to 0. The memories numbered from 1 to N correspond to the power channels numbered from 1 to N. Set memories numbered from 1 to 12, and all initialize the stored value to 0;

[0074] Second, traverse the priority values of the power channels from 1 to N once, and set the stored value of the memory corresponding to the priority value to 1, that is, traverse the priority values of all 12 power channels once, and set the stored value of the memory corresponding to the priority value to 1.

[0075] Finally, check whether there is a memory with a stored value of 0 in the memories from 1 to N; if there is, the priority level configuration data is incorrect, and the detection is stopped; if not, the priority level configuration data meets the requirements. Check all 12 memories to see if there is a memory with a stored value of 0. As long as it is detected that there is, the priority level configuration data sent by the user is incorrect (the remaining unexamined memories do not need to be checked further); if not, the priority level configuration data meets the requirements.

[0076] To better illustrate the above checking process, taking 12 output power channels as an example for detailed description, there must be 12 priority levels: p(1), p(2), p(3), …… p(n - 1), p(n) (where n = 12).

[0077] For example, if the user sets the priorities of 12 output power channels as:

[0078]

[0079] Preset 12 priority memories

[0080] Level 1 Level 2 Level 3 Level 4 Level 5 Level 6 Level 7 Level 8 Level 9 Level 10 Level 11 Level 12 0 0 0 0 0 0 0 0 0 0 0 0

[0081] Traverse the user priority setting value

[0082] Level 1 Level 2 Level 3 Level 4 Level 5 Level 6 Level 7 Level 8 Level 9 Level 10 Level 11 Level 12 1 1 1 1 1 0 1 1 1 1 1 1

[0083] Check whether there is a memory with a stored value of 0

[0084] Level 1 Level 2 Level 3 Level 4 Level 5 Level 6 Level 7 Level 8 Level 9 Level 10 Level 11 Level 12 0

[0085] It is detected that priority 6 is not set and the power channel priority value set by the user is incorrect.

[0086] To better illustrate the process of the in-vehicle multi-channel power switch control method in the embodiments of the present application, as Figure 3 shown, the following steps are used for detailed description:

[0087] S1, Start.

[0088] S2, Whether the storage module loads all configuration parameters. If not, load the configuration parameters by default.

[0089] S3, Start initializing the configuration.

[0090] S4, Whether the power channel with priority n needs to be configured.

[0091] When the in-vehicle intelligent power box starts up, it loads the configuration parameters of all channels from the memory. The configuration parameters include priority level, switch control, delay time, and other configuration items. If the user has not set the configuration parameters through CAN, then at startup, the system default configuration parameters are loaded, such as the priority order according to the power output channel number sequence. In addition, the power channels with relatively higher priorities can be preferentially controlled both when starting up and shutting down.

[0092] The form of the start-stop timing control configuration parameters for each output channel by the user is as Figure 4 shown. Each power channel (C1, C2...) must have a unique priority level P, and the delay time d and the switch control state s can be any reasonable values. It is not allowed for the user to set two power channels with the same priority level. The configuration parameters sent by the user through the CAN bus may be incorrect, especially the priority configuration parameter P.

[0093] S5, Configure the output state of power channel n.

[0094] S6, Start the timing module according to the configuration parameters of channel n.

[0095] After the configuration parameters are loaded, traverse the power output channels that need to be configured in sequence according to the priority order. When one or several output channels are defaulted to the off state, there is no need to configure them and they can be directly skipped (if they need to be turned on later, they will still be configured to turn on in the priority order).

[0096] S7, whether the timing time of the timing module has reached.

[0097] The delay time of the timing module is the cumulative time starting from the end of the previous channel configuration, that is, the interval time between the start and stop of adjacent power channels.

[0098] For the start and stop timing control of the power channel, the same configuration parameters can be used, or two sets of configuration parameters can be set, one for the start timing of the power channel and one for the stop timing of the power channel.

[0099] S8, determine whether all power channels have been configured.

[0100] S9, if not, switch to the next priority channel, if so, set the end flag of the configuration process.

[0101] S10, end.

[0102] The embodiment of the present application also provides a vehicle-mounted power supply box 500, as Figure 5 shown, provides a schematic structural diagram of the vehicle-mounted power supply box in the embodiment of the present application. The vehicle-mounted power supply box 500 includes: a power start-stop timing control module, the power start-stop timing control module is connected to multiple power output channels, and the power start-stop timing control module includes: a CAN communication module 510, a vehicle-mounted power supply box main control module 520, and a configuration storage module 530.

[0103] In an embodiment of the present application, the CAN communication module 510 is specifically used as a configuration interface for the multiple power output channels to receive the configuration parameters of each power output channel. The configuration parameters include at least one of the following: priority level, delay time, output power parameters, switch control status. The priority level includes a start priority level and a stop priority level.

[0104] The vehicle-mounted power supply box starts after being powered on, and the configuration parameters of each power output channel will be loaded after startup. It should be noted that the configuration parameters of each power output channel are pre-configured. If there is no pre-configuration, the default configuration parameters will be loaded for the initialization configuration process.

[0105] Further, the configuration parameters include, but are not limited to, priority level, delay time, output power parameters, and switch control status.

[0106] In some embodiments, if the user has not set the configuration parameters through the CAN bus, the system default configuration parameters will be loaded at startup. It can be understood that the default configuration parameters can be a feasible default parameter, which is a configuration with the power output channel number sequence as the priority sequence.

[0107] In one embodiment of the present application, the vehicle-mounted power supply box main control module 520 is specifically configured to sequentially traverse and configure the configuration parameters in the power output channels according to the start priority level, so as to perform start control on the power output channels;

[0108] It is also used to, when the vehicle-mounted power supply box enters the sleep state or receives an instruction to close multiple power output channels, sequentially traverse and configure the configuration parameters in the power output channels according to the close priority level, so as to perform close control on the power output channels. The multiple power control module is used to execute the start and stop of multiple power output channels according to the control instruction of the vehicle-mounted power supply box main control module.

[0109] Since the start priority level is included in the priority level, the start priority level sequentially traverses and configures the configuration parameters in the power output channels. That is to say, after the configuration parameters are loaded, the power output channels to be configured are sequentially traversed in the priority order (start priority level). When one or several output channels are defaulted to the closed state, there is no need to configure them, and they can be directly skipped to the next power output channel.

[0110] It should be noted that the power channels with relatively higher priorities can be preferentially controlled when starting.

[0111] It can be understood that for the power output channels, there are only two different states: start or close, that is, providing power or not providing power. The state of the switch is defaulted to off or defaulted to on. For the intelligent sensing peripheral kit of autonomous driving, different sensor peripherals such as lidar, millimeter wave radar, camera, domain controller, etc. have different control requirements for power. Through the above configuration optimization method, the timing and priority of multiple power supplies can be independently controlled, and there is no need for an external controller to intervene in scheduling, so as to meet the power supply timing requirements of various autonomous driving kits and improve the power supply efficiency of the power supply box.

[0112] In one embodiment of the present application, the configuration storage module 530 is specifically configured to store the configuration parameters of each power output channel.

[0113] An embodiment of the present application provides a vehicle-mounted multi-channel power switch control device, where it is used for a vehicle-mounted power supply box, and the device includes:

[0114] A loading module, used for the vehicle-mounted power supply box to power on and start, and load the configuration parameters of each power output channel, where the configuration parameters at least include one of the following: priority level, and the priority level includes a start priority level;

[0115] A traversal configuration module for traversing and configuring the configuration parameters in the power output channels in sequence according to the startup priority level to perform startup control on the power output channels.

[0116] It further includes: a detection module for detecting whether the priority level in the configuration parameters of each power output channel is valid. The detection steps include:

[0117] Set memories numbered from 1 to N, and all are initialized with a stored value of 0. The memories numbered from 1 to N correspond to the power channels numbered from 1 to N.

[0118] Traverse the priority values of the power channels numbered from 1 to N once, and set the stored value of the memory corresponding to the priority value number to 1.

[0119] Check whether there is a memory with a stored value of 0 in the memories numbered from 1 to N.

[0120] If there is, the priority level configuration data is incorrect, and the detection stops.

[0121] If not, the priority level configuration data meets the requirements.

[0122] Figure 6 It is a schematic structural diagram of an electronic device according to an embodiment of the present application. Please refer to Figure 6 , at the hardware level, the electronic device includes a processor, and optionally also includes an internal bus, a network interface, and a memory. Among them, the memory may include a memory, such as a high-speed random access memory (Random-Access Memory, RAM), and may also include a non-volatile memory, such as at least one disk memory, etc. Of course, the electronic device may also include other hardware required for other services.

[0123] The processor, network interface, and memory can be interconnected through an internal bus. The internal bus can be an ISA (Industry Standard Architecture) bus, a PCI (Peripheral Component Interconnect) bus, or an EISA (Extended Industry Standard Architecture) bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For the sake of representation, Figure 6 only a two-way arrow is used in

[0124] A memory for storing programs. Specifically, the program may include program code, and the program code includes computer operation instructions. The memory may include a memory and a non-volatile memory, and provide instructions and data to the processor.

[0125] The processor reads the corresponding computer program from the non-volatile memory into the memory and then runs it, forming a vehicle-mounted multi-channel power switch control device at the logical level. The processor executes the program stored in the memory and is specifically used to perform the following operations:

[0126] The vehicle-mounted power supply box is powered on and starts, loading the configuration parameters of each power output channel, where the configuration parameters at least include one of the following: priority level, delay time, output power parameters, switch control status, and the priority level includes a startup priority level;

[0127] Traverse and configure the configuration parameters in the power output channels in sequence according to the startup priority level to perform startup control on the power output channels.

[0128] The above method executed by the vehicle-mounted multi-channel power switch control device disclosed in the embodiments of the present application Figure 2 can be applied to or implemented by the processor.
