Detailed Description
The present application will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present application more apparent.
It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present application should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present application belongs. The terms "first," "second," and the like, as used in embodiments of the present application, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
As described in the background art, the controller of the vehicle may implement control of the vehicle in a layered architecture, where the controller is divided into ASW (Application Software Layer, application layer), RTE (Runtime Environment, running environment layer), BSW (Basic Software Layer, bottom layer) and control unit from top to bottom, where the application layer is located at an upper layer of the running environment layer, the running environment layer is located at an upper layer of the bottom layer, the bottom layer is located at an upper layer of the control unit, software of the controller includes the application layer, the running environment layer and the bottom layer, and hardware of the controller includes the control unit.
In order to ensure the independence of the application layer, the operation environment layer, the bottom layer and the control unit, each layer can only use the interface provided by the next layer and provide a corresponding interface for the previous layer. Thus, the software and hardware in the vehicle controller are separately developed and verified through the layered architecture of the controller.
In order to realize low-power-consumption operation of the controller, when a network connected with the controller meets a preset dormancy condition, the controller and the network enter a dormancy state together; when the controller and the network are in a dormant state, the controller and the network enter a working state together when the controller acquires a wake-up signal, wherein the power consumption of the working state is larger than that of the dormant state.
Specifically, the network wake-up method in the related art is implemented by enabling the bottom layer and the application layer in the controller to enter the wake-up working state from the sleep state. When the network in the vehicle is in a dormant state, the controller can monitor a wake-up signal in the vehicle through a wake-up component in the application layer, when the wake-up component monitors that the vehicle has the wake-up signal, the wake-up component generates wake-up instructions for waking up the application layer and the bottom layer, the application layer and the bottom layer are waken up from the dormant state, then the application layer generates a network wake-up instruction, and the network wake-up instruction is sent to the network through the bottom layer, so that the network enters the wake-up state from the dormant state.
The problems with this are: under the condition that an application layer, a bottom layer and a control unit in the controller enter a dormant state, when the controller acquires a wake-up signal, the controller and the network enter a working state together, however, signals which cannot be processed by the controller and the network exist in the wake-up signal, and for the wake-up signal, the controller and the network enter the working state together from the dormant state, the power consumption of the controller and the network can be increased, and the service life of electronic devices in the controller can be reduced.
Therefore, in order to improve the wake-up efficiency of the network and extend the service life of the controller electronics, a wake-up mode of the network is needed that can filter the wake-up signal.
As shown in fig. 1, the method of the present embodiment is applied to a controller, where the controller includes a bottom layer and an application layer, and the bottom layer is communicatively connected to a network, and the method of the present embodiment includes:
step 101, obtaining a wake-up signal through the wake-up component, and sending the wake-up signal to the bottom layer.
In this step, the wake-up signal refers to a signal capable of waking up the bottom layer from the Sleep state, and the preferred wake-up signal in this embodiment may be a signal obtained by a wake-up component that is always in an operating state and capable of waking up the bottom layer from the Sleep state, for example, the controller may be a vehicle body domain controller, the application layer may be an ASW in an AUTOSAR (Automotive Open System Architecture, open system architecture) in the vehicle body domain controller, the bottom layer may be a BSW in an AUTOSAR in the vehicle body domain controller, the wake-up component may be an SLP (Sleep Model) in the ASW, and the wake-up signal may be a signal generated according to a Pin signal obtained by the wake-up component and transmitted by hard wire, or may be a signal generated according to an NM (Network Management, network management message) transmitted by the communication network.
It will be appreciated that when the controller is in a sleep state, a portion of the control units will always be in operation in order to acquire the wake-up signal of the controller.
And step 102, sending the wake-up signal to an application layer through the bottom layer.
In this step, the bottom layer refers to software capable of providing basic services, the application layer refers to software capable of providing control algorithms, for example, the application layer may be ASW in AUTOSAR in the vehicle body domain controller, and the BSW may send Pin signals and NM messages to the ASW through an interface module in the BSW. In this way, the wake-up signal is sent to the application layer through the bottom layer, so that the matching of the wake-up signal by the bottom layer is avoided, and the step-by-step processing of the wake-up signal is realized.
And step 103, matching the wake-up signals by using the application layer by adopting a pre-stored wake-up rule to obtain a matching result.
In this step, the wake-up rule refers to a rule that can filter the wake-up signal, and the matching result refers to a result obtained by matching the wake-up signal according to the wake-up rule. For example, when the wake-up signal is an NM message about pulling the door handle, the wake-up rule corresponding to the wake-up signal may be that pulling the door handle needs to send a door opening signal when a car key signal is present, and then the NM message pulling the door handle may be matched with whether the car key signal is present.
And 104, generating a wake-up instruction by the application layer according to the matching result, and sending the wake-up instruction to a bottom layer.
In this step, the wake-up instruction refers to an instruction that can be used to wake up the network at the bottom layer, e.g., the wake-up instruction can be generated by a wake-up function in the application layer.
And 105, waking up the network in the dormant state by using the wake-up instruction through the bottom layer.
In this step, the network refers to a unit capable of providing a communication function to the bottom layer, and for example, the network may include a LIN (Local Interconnect Network, local bus) network and a CAN (Controller Area Network ) network.
According to the scheme, the wake-up signal is sent to the application layer through the bottom layer, so that the fact that the bottom layer is used for completing matching of the wake-up signal is avoided, and step-by-step processing of the wake-up signal is realized; the application layer is utilized to match the wake-up signals according to the wake-up rule, wake-up instructions of the wake-up network are obtained according to the matching result, the wake-up signals are filtered through the wake-up rule, the wake-up signals which do not accord with the wake-up rule are prevented from being generated, the number of network wake-up times is reduced, and therefore the power consumption of the whole vehicle is reduced.
In some embodiments, the wake-up component is coupled to a state unit; the step expansion of step 101 specifically includes:
sending a query signal to the state unit by the wake-up component with a preset period;
receiving a state signal which is sent by the state unit and is obtained according to the query signal through the awakening component;
generating the wake-up signal by the wake-up component from the status signal.
In the above scheme, the state unit refers to a unit where the state signal is located, for example, the state signal may be a Pin signal in an integrated circuit of an MCU (Microcontroller Unit, micro control unit) of a body domain controller in a vehicle, or may be an NM message in a CAN network link, and the state unit may be a Pin angle in the integrated circuit or may be a CAN network link.
Specifically, when the bottom layer, the application layer and the network are in a dormant state, the wake-up component in the controller is always in a working state, and the wake-up component acquires a state signal of the state unit in a periodic polling mode and determines the wake-up signal according to the state signal. For example, the SLP acquires a vehicle body Pin signal by hard wiring, and when the Pin signal is at a high level, the SLP generates a wake-up signal and transmits the wake-up signal to the floor layer.
By the scheme, a data basis is provided for subsequent generation of the wake-up signal.
In some embodiments, the status signal includes at least one of: pin level and network message;
the generating, by the wake-up component, the wake-up signal from the status signal includes:
in response to determining that the pin level is different from a pre-stored level signal or that the network message is present, generating, by the wake-up component, the wake-up signal according to a pre-stored signal function.
In the above scheme, the Pin level refers to a signal obtained through hard wiring, the network message refers to a signal obtained through a communication network link, for example, when the Pin signal is at a high level, and is different from a pre-stored low level signal, a signal function is adopted to generate a corresponding wake-up signal according to the high level signal; when NM message exists in the CAN network link, a signal function is adopted to generate a corresponding wake-up signal according to the NM message. By the scheme, a data basis is provided for the generation of the subsequent initial wake-up instruction and the wake-up instruction.
In some embodiments, step 102 specifically includes:
generating an initial wake-up instruction according to the wake-up signal by the wake-up component, wherein the initial wake-up instruction is used for waking up the bottom layer;
and sending the wake-up signal to the application layer through the bottom layer.
In the above solution, the initial wake-up instruction refers to an instruction capable of waking up the bottom layer, for example, the initial wake-up instruction may be generated by an initial wake-up function in the wake-up component, after the initial wake-up instruction wakes up the bottom layer, the bottom layer is turned from a sleep state to a working state, and the bottom layer in the working state may send a wake-up signal to the application layer through interfaces of the bottom layer and the application layer.
By the scheme, the generation of the initial wake-up instruction realizes the step-by-step wake-up of the bottom layer and the application layer in the controller, and the bottom layer and the application layer are prevented from entering the working state from the dormant state after the wake-up signal is acquired.
In some embodiments, step 103 shown in fig. 2 specifically includes:
step 1031, searching matching data corresponding to the wake-up signal from the wake-up rule by using the application layer;
step 1032, obtaining data to be matched corresponding to the wake-up signal by using the application layer;
step 1033, comparing the data to be matched with the matching data by using the application layer to obtain a comparison result;
and 1034, generating the matching result according to the comparison result by using the application layer.
In the above scheme, the matching data refers to data capable of filtering the wake-up signal in the wake-up rule, for example, when the wake-up signal is an NM message about pulling the door handle, the wake-up rule corresponding to the wake-up signal may be that the door handle needs to be pulled to send a door opening signal when a car key signal is present, the matching data is that the car key signal needs to be present, the car key signal exists when the door handle is pulled, and when the comparison result is that the car key signal exists when the door handle is pulled, the NM message corresponding to the wake-up signal is a matching success signal.
Through the scheme, the wake-up signals are filtered through the wake-up rule, so that the wake-up instructions of the wake-up signals which do not accord with the wake-up rule are prevented from being generated, the number of network wake-up times is reduced, and the power consumption of the whole vehicle is further reduced.
In some embodiments, step 104 specifically includes:
in response to determining that the comparison result is that the data to be matched are identical to the matching data, setting a wake-up signal in the matching result as a matching success signal by using the application layer;
and in response to determining that the comparison result is that the data to be matched is different from the matching data, setting a wake-up signal in the matching result as a matching failure signal by using the application layer.
In the above scheme, the matching success signal refers to a wake-up signal conforming to a wake-up rule, the matching failure signal refers to a wake-up signal not conforming to a wake-up rule, for example, when the wake-up signal is an NM message about pulling a door handle, the wake-up rule corresponding to the wake-up signal may be that the door handle needs to be pulled to send a door opening signal when a car key signal exists, the matching data is that the car key signal exists when the door handle is pulled, and when the comparison result is that the car key signal exists when the door handle is pulled, that is, the data to be matched is the same as the matching data, and the NM message of the door handle is the matching success signal; when the comparison result is that the vehicle key signal does not exist when the door handle is pulled, namely the data to be matched is different from the matching data, the matching result is that the NM message of the door handle is pulled is a matching failure signal.
Through the scheme, the wake-up signals are classified according to the wake-up rules, so that the matching success signals and the matching failure signals are obtained, and a judgment basis is provided for the subsequent application layer to wake-up the network.
In some embodiments, step 105 specifically includes:
generating the wake-up instruction by using the application layer in response to determining that the wake-up signal in the matching result is a matching success signal;
and generating a dormancy instruction by using the application layer and sending the dormancy instruction to the bottom layer in response to the fact that the wake-up signal in the matching result is a matching failure signal, wherein the dormancy instruction is used for dormancy of the bottom layer.
In the above scheme, when the wake-up signal is a matching success signal, it means that the wake-up signal can be transmitted in a network connected with the bottom layer; when the wake-up signal is a match failure signal, it indicates that the wake-up signal cannot be transmitted in the network connected to the bottom layer.
Specifically, when the wake-up signal is obtained, the wake-up component in the application layer wakes up the bottom layer according to the initial wake-up instruction, then transmits the wake-up signal to the application layer through the bottom layer, and the application layer judges the wake-up signal through the wake-up rule to determine whether to wake up the network connected with the bottom layer. Because the application layer does not generate a wake-up instruction of the network according to the matching failure signal, the wake-up of the matching failure signal to the network is avoided, so that the wake-up times of the network are reduced, and the power consumption of the whole vehicle is further reduced.
By the scheme, the application layer generates the dormancy instruction of the bottom layer according to the matching failure signal, so that the continuous awakening of the matching failure signal to the bottom layer is avoided, and the power consumption of the bottom layer is reduced.
It should be noted that, the method of the embodiment of the present application may be performed by a single device, for example, a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the method of an embodiment of the present application, the devices interacting with each other to accomplish the method.
It should be noted that the foregoing describes some embodiments of the present application. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments described above and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
Embodiments of the present application may further include:
step 1, firstly, the MCU (corresponding to the control unit in the embodiment of the present application) will poll the hard wire wake-up source PIN angle periodically and monitor the CAN (Controller Area Network ) network channel.
And step 2, if the PIN angle level changes or any message exists in the CAN network channel, firstly, the domain controller wakes up the bottom layer, after the bottom layer operates, the bottom layer wakes up the application layer, and the bottom layer transmits data to the application layer through the interface.
And 3, the application layer judges whether the wake-up source is legal (corresponding to the successful matching signal in the embodiment of the application), and if the wake-up source is legal, the application layer sends down instructions to the bottom layer to wake up CAN and LIN (Local Interconnect Network, local bus) networks. If the source is not legal awakening source, a dormancy instruction is issued to the bottom layer, so that the bottom layer can continue sleeping.
The wake-on-network method of the above embodiment has the beneficial effects of the wake-on-network method of any of the foregoing embodiments, and is not described herein again.
