Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

FIG. 1 is a block diagram illustrating an integrated control chip in accordance with an exemplary embodiment. As shown in fig. 1, a plurality of control modules 121 to 126 corresponding to a plurality of vehicle-mounted components one to one and a main control module 110 are integrated in the integrated control chip 100, wherein the control modules 121 to 126 are used for being called by the main control module 110 to implement a plurality of operations associated with the corresponding vehicle-mounted components;

the integrated control chip is also provided with at least one data stream corresponding to at least one event one by one, each data stream is formed by connecting a plurality of operation nodes in series, and each data stream comprises operation nodes in different node streams;

In an exemplary embodiment, the main control module 110 may be implemented by one or more Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), Digital Signal Processing Devices (DSPDs), Programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components. In another exemplary embodiment, the control modules 121-126 may be implemented in the form of hardware, or may be implemented in the form of software functional units. The software functional unit is stored in a storage medium and includes a plurality of functional functions for executing the functional functions when the main control module 110 calls the control module. And the aforementioned storage medium includes: Read-Only Memory (ROM), Random Access Memory (RAM), and other various media capable of storing program codes.

With regard to the relationship of the control modules and the in-vehicle components, in particular, a single in-vehicle component corresponds to one of the plurality of control modules in the integrated control chip. When some vehicle-mounted components need to be used, control modules corresponding to the vehicle-mounted components can be called through the main control module, and relevant operations of the vehicle-mounted components corresponding to the control modules are realized through the control modules, and a single operation can be a specific action executed by the vehicle-mounted components, such as sending information, processing information or outputting information.

For example, the single vehicle-mounted component may be any one of a radar, a buzzer, a meter, a vehicle-mounted air conditioner, a vehicle lamp system and a smart key, and in one possible embodiment, as shown in fig. 1, the control module 121 is a control module corresponding to a radar, and when it is required to perform some operations using the radar, such as transmitting a radar wave for detecting an obstacle, the main control module 110 calls the control module 121 and then controls the radar to transmit the radar wave.

For node flow, a schematic diagram of data flow and node flow in an integrated control chip is exemplarily shown with reference to fig. 2. As shown in fig. 2, the control module 121 is a control module corresponding to a radar, the operation node 1211 corresponds to an operation of transmitting a radar wave for detecting an obstacle, the operation node 1212 corresponds to an operation of receiving the transmitted radar wave, and the operation node 1213 corresponds to an operation of resolving the received radar wave, so that the operation node 1211, the operation node 1212, and the operation node 1213 form a node flow corresponding to the control module 121, and the operation nodes 1211 to 1213 are arranged in the node flow in an order of executing the operation node 1211, then executing the operation node 1212, and finally executing the operation node 1213. Similarly, referring to FIG. 2, the node flows formed by the operation nodes 1221-1223 correspond to the control module 122, and the node flows formed by the operation nodes 1231-1233 correspond to the control module 123.

Still taking fig. 2 as an example, for the data flow, the control module 121 is a control module corresponding to a radar, the control module 122 is a control module corresponding to a buzzer, the control module 123 is a control module corresponding to a meter, the operation node 1211 of the control module 121 is operated to obtain data information, for example, an obstacle monitored by the radar may be located in one of 5 distance ranges, such as 0 to 0.5m, 0.5m to 1m, 1m to 1.5m, 1.5m to 2m, 2m to 6m, and the obtained data information is data information indicating that the obstacle is located in one of the 5 distance ranges. The operation node 1222 of the control module 122 is configured to control the buzzer to beep at a frequency corresponding to the distance range based on the data information obtained by the operation node 1211, for example, the buzzer may beep at a frequency of 2kHz, 1kHz, 500Hz, 250Hz, and 125Hz, and 2kHz corresponds to 0-0.5 m, 1kHz corresponds to 0.5 m-1 m, 500Hz corresponds to 1 m-1.5 m, 250Hz corresponds to 1.5 m-2 m, and 125Hz corresponds to 2 m-6 m, that is, when the obtained data information indicates that the obstacle is located at 0-0.5 m, the buzzer beeps at a frequency of 2kHz, and the rest is the same. The operation node 1233 of the control module 123 corresponds to an operation of displaying the distance of the obstacle with respect to the vehicle on the meter based on the acquired data information.

Referring to the above description of the operation corresponding to the operation node, the event is completed by a data stream, and the data stream is formed by connecting a plurality of operation nodes in series, and each data stream includes operation nodes in different node streams. Specifically, the vehicle event may be composed of a plurality of operations in a certain order, and a data stream is formed by configuring a plurality of operation nodes in one-to-one correspondence with the plurality of operations, thereby completing a specific event. For example, for an event in which an obstacle distance is monitored by radar, a buzzer is controlled to beep according to information about the distance, and information about the distance is displayed on a meter, a data stream may be formed by configuring the operation node 1211, the operation node 1222, and the operation node 1233 in series in this order.

In one possible embodiment, the main control module 110 first calls the control module 121 to perform an operation corresponding to the operation node 1211, the data information obtained by the radar indicates that the obstacle is located in the range of 0.5m to 1m, then the main control module 110 calls the control module 122 to perform an operation corresponding to the operation node 1222, the buzzer is controlled to buzz at the frequency of 1kHz, and finally the main control module 110 calls the control module 123 to perform an operation corresponding to the operation node 1233, and the distance of the obstacle from the vehicle is displayed on the meter in the range of 0.5m to 1 m. Of course, the data information acquired by the radar may also include the direction of the obstacle relative to the vehicle, for example, the left front direction, and thus a buzzer located at the left front direction on the vehicle may be controlled to beep, and the obstacle located at the left front direction on the vehicle may be displayed on the meter.

Regarding the calling of the control module by the main control module, for example, for the control modules 121 to 126 in fig. 1, the

control modules

121, 122, 123, 124, 125 and 126 may be called in sequence, when the control module 121 is called, as shown in fig. 2, each operation node is traversed in sequence according to the sequence of the operation node 1211, the operation node 1212 and the operation node 1213, and when the control module 122 is called, each operation node is traversed in sequence according to the sequence of the operation node 1221, the operation node 1222 and the operation node 1223.

With respect to whether the main control module performs corresponding operations on the traversed operation nodes, following the above example, as shown in fig. 2, for the operation nodes 1221 to 1223 in the control module 122, when traversing to the operation node 1221, since the operation node 1221 is not located in any data stream, the operation corresponding to the operation node 1221 is not performed, and the data stream is transferred to the traversal operation node 1222, since the operation node 1222 is located in the data stream formed by the operation node 1211, the operation node 1222 and the operation node 1233, it can be detected whether the operation node 1211, which is the previous operation node of the operation node 1222 in the data stream, is in a complete state, the operation corresponding to the operation node 1222 is performed if the operation node 1211 is in the complete state, and the operation corresponding to the operation node 1222 is not performed if the operation node 1211 is in the incomplete state. It should be noted that, when traversing to an operation node, no matter whether the operation corresponding to the operation node is executed, after traversing the operation node, the next operation node in the node flow where the operation node is located is traversed. In addition, if the operation node is located in the data stream and the operation node is the first node in the data stream, the operation corresponding to the operation node is directly executed without detecting whether the previous operation node in the data stream is in the completed state.

That is, the main control module may sequentially invoke each control module in a certain order, and the invoking process may be performed in a loop, and the loop may be started when the vehicle is started. For the control module being called, that is, the target control module, the main control module may traverse each operation node in the node stream corresponding to the control module according to the serial order of the operation nodes in the node stream corresponding to the control module, and determine whether to execute the operation corresponding to the operation node this time.

It is noted that, in implementation, there may be a certain control module that can independently perform certain events independently of the data of other control modules. In this case, when the master control module traverses to an operation node in a node flow corresponding to the control module, even if the operation node does not belong to any data flow, the operation corresponding to the operation node is still executed.

The adoption of the integrated control chip can comprise the following technical effects:

when a certain event needs to be realized by using the vehicle-mounted component, a data stream capable of realizing the event is formed by configuring operation nodes on a node stream corresponding to a control module in an integrated control chip, and when each control module is called in turn and circularly according to the traversal time parameter of each node stream, the operation node in the data stream judges whether to execute the operation node in the data stream along with the traversal of each operation node in the called control module, and when the operation node in the data stream is determined to be executed, the corresponding event is realized. Because the cyclic calling of the control module and the traversal of the operation nodes in the control module are sequentially carried out, corresponding events can be realized by configuring operation points in the data stream, a controller is not required to be independently configured for each vehicle-mounted component on the vehicle, and the development cost of the vehicle is reduced.

Further, for a vehicle event, the system is typically required to respond within a certain time frame after the event is triggered, which causes the data stream corresponding to the vehicle event to have an execution duration limit. The operation of the data stream depends on the cyclic traversal of the node stream, so the time of the cyclic traversal of the node stream directly influences the execution duration of the data stream. In this case, it is necessary to reasonably plan the traversal time parameter of each node flow to ensure that the execution of each data flow meets the execution time requirement (response time of the event corresponding to the data flow). Therefore, the main control module is further configured to determine a traversal time parameter of each node flow according to the execution duration limitation information of each data flow.

That is, in the vehicle operation, the traversal time parameter of each node flow associated with each data flow may be determined according to the execution duration limit information of the data flow. In this way, the main control module cyclically and sequentially calls each control module according to the determined traversal time parameter, and traverses each operation node in the node flow corresponding to the target control module aiming at the target control module called each time, so that the operation of each data flow can be ensured to meet the corresponding execution time requirement.

The traversal time parameter may include an execution period and/or an execution duration of the node flow, where the execution period is used to indicate how often the node flow needs to be executed, and the execution duration is used to indicate a duration taken by each execution of the node flow.

In a possible implementation manner, the main control module is further configured to:

It should be noted that, for a specific resource allocation priority order of multiple data flows, when the master control module sequentially adjusts the traversal time parameters of the node flows related to each data flow according to the priority order, the master control module preferentially adjusts the traversal time parameters of the node flows related to the data flows with high priority to meet the execution duration requirement of the data flow (the requirement is indicated by the execution duration limitation information) until the traversal time parameters of each node flow corresponding to each data flow are adjusted, so as to obtain the final traversal time parameters of each node flow.

That is to say, by adopting the particle swarm algorithm, the master control module can continuously optimize the resource allocation priorities of the multiple data streams, and continuously adjust the traversal time parameters of the node streams corresponding to the data streams from the data stream with high priority until the final traversal time parameters of the node streams are obtained according to the finally obtained resource allocation priorities of the data streams. In this way, the main control module cyclically and sequentially calls each control module according to the determined traversal time parameter, and traverses each operation node in the node flow corresponding to the target control module aiming at the target control module called each time, so that the operation of each data flow can be ensured to meet the corresponding execution time requirement.

In a possible implementation manner, the main control module is configured to:

In this way, by setting the parameter of the waiting time for each operation node, for each generated set of priority assignment information, the operation goodness coefficient of the integrated control chip under the priority assignment information can be determined by the waiting time of each operation node under the priority assignment information, so that the priority assignment information meeting the requirement can be selected according to the operation goodness coefficient. And finally, setting resource allocation priorities for the plurality of data streams according to the priority allocation information meeting the requirements so as to meet the execution duration requirements of the data streams.

In another possible implementation manner, the main control module is configured to:

That is to say, when the operation quality coefficients corresponding to the multiple sets of priority allocation information generated by the main control module do not meet the execution duration requirement of the node stream, the main control module can also update the multiple sets of priority allocation information according to the particle swarm algorithm, and finally find the priority allocation information which can meet the execution duration requirement of each node stream by continuously optimizing the priority allocation information through the particle swarm algorithm.

Optionally, the speed update formula of a single data stream particle in the particle swarm optimization is represented as:

V_iis the flight velocity of the ith data stream particle, and

alpha is a constraint factor.

By adopting the integrated control chip, the execution of the data stream can be ensured to meet the requirement of time limit by planning the resources of the data stream (namely adjusting the traversal time parameter of the node stream related to the data stream), and a controller is not required to be independently configured for each vehicle-mounted component on the vehicle, thereby reducing the development cost of the vehicle.

Optionally, the main control module is further configured to:

Wherein, the following node parameters can be set for each operation node:

and whether a data information flag bit DRF is needed or not is used for representing whether the execution of the operation node needs to wait for the data information of the previous data flow node or not. If DRF is 1, it indicates that the operation node needs to wait for the data information of the previous data flow node, and the operation node cannot execute the data information in the absence of the data information. DRF-0 means that the operating node does not need to wait for data information.

And the waiting time DWT is used for recording the time that the operation node has waited for the data information, and the waiting time refers to the time that the node flow to which the operation node belongs is traversed before the operation corresponding to the operation node is executed after the first node in the data flow is marked as the completed state.

Reasonable waiting time DWT_optAnd the operation node is used for representing the reasonable waiting times of the operation node, and the execution state of the operation node is considered to be good under the reasonable waiting times.

Illustratively, each of the reasonable wait times may be DWT for each operational node_optAs a preset number threshold for the operational node. The air conditioner control module isFor example, if there are 5 operation nodes needing to wait for data information in the node stream corresponding to the air conditioning control module, the control good coefficient of the air conditioning control module

i is the number of an operation node needing to wait for data information in the same node flow, and each control good coefficient can be used as a running good coefficient in specific implementation.

In this way, the operation index of the waiting times is set for each operation node, and the main control module can determine the operation state of each control module by comparing the waiting times with the corresponding preset time threshold value by setting the preset time threshold value for each operation node. And then determining the operation good coefficient of the integrated control chip according to the operation state of each control module, and finally judging whether the current resource allocation information accords with the expectation according to the operation good coefficient, thereby being beneficial to searching the traversal time parameter meeting the execution time limit information of each data stream.

Optionally, the main control module is configured to:

That is, the control goodness coefficient may also be represented as an average value of each control goodness coefficient, i.e., a system goodness coefficient. The states of the control modules under the specific resource allocation information are integrally evaluated through the system good coefficient, the screening efficiency of the resource allocation information is further improved, and the traversal time parameters meeting the execution time limit information of each data stream are searched.

Illustratively, whether a data information flag bit DRF is needed or not and a reasonable waiting time DWT are set for each operation node_optOn the basis of the waiting time DWT, the following parameters can be set for the operation node:

maximum wait time DWT_maxAnd the function module is used for representing the maximum waiting times of the operation node, and if the waiting times of the operation node is greater than the maximum waiting times, the function of the operation node is invalid.

In particular, the sum of the wait times of each operation node in each node flow and the reasonable wait time DWT of each operation node can be implemented_optAs a control merit coefficient of the control module corresponding to the node flow:

i is the number of the operation node needing to wait for the data information in the same node flow. The first reasonable coefficient range may be set to

Wherein, each operation node is subjected to DWT with maximum waiting times_maxWith reasonable wait times DWT_optThe ratio of (A) is recorded as Noef_max. Specifically, for a certain control module, when the nodf value is less than 1, the control module is in a superior state, and the state of the control module is superior as the nodf value is smaller. Noef maximum value is Noef_maxThe closer the Noef value is to the Noef_maxThe worse the operating state of the control module. The optimal state of the control module is

That is, all the operation nodes do not wait, and the Nodef value is 0 at this time; the worst state Noef value of the control module is Noef_maxAt this time, the waiting times of all the operation nodes in the node flow corresponding to the control module all exceed the maximum waiting time of the operation node, and in this case, the data flow to which the operation node in the node flow belongs is in a failure state, and the functional event corresponding to the data flow cannot be realized.

Further, an average value of each of the control merit coefficients may be taken as a system merit coefficient:

wherein i is the number of the control module, and n is the number of the control modules in the system. When Sysf value is at

(i.e., the second reasonable coefficient range), the system is considered to be in good operation, where

Therefore, by adopting the integrated control chip, the main control module can monitor the running states of each control module and the operation node corresponding to each control module in real time by setting two indexes of the good control coefficient and the good system coefficient and setting intervals for the good control coefficient and the good system coefficient respectively. That is, the main control module can determine the traversal time parameter of each node flow associated with each data flow according to the execution duration limitation information of the data flow by using the control goodness coefficient and the system goodness coefficient as indexes. In this way, the main control module cyclically and sequentially calls each control module according to the determined traversal time parameter, and traverses each operation node in the node flow corresponding to the target control module aiming at the target control module called each time, so that the operation of each data flow can be ensured to meet the corresponding execution time requirement.

In a possible implementation manner, the traversal time parameter includes an execution duration and an execution period of the node flow, and the main control module is configured to:

For example, in a specific implementation, the section range may be set for each operation node, and the operation goodness coefficient of the integrated control chip is determined by obtaining a waiting number section in which the waiting number of the operation node in each data stream in the commissioning process is located.

In this way, by setting the operation index of the waiting times for each operation node, the main control module can determine the operation quality coefficient of the integrated control chip through the operation index, and further judge whether the resource allocation priority and the traversal time parameter of the current data stream meet expectations according to the operation quality coefficient, which is beneficial to screening the resource allocation priority of the data stream.

Optionally, the main control module is further configured to:

It should be noted that the data streams may be configured in the integrated control chip before the vehicle leaves the factory, each data stream may include an activation flag, and when the activation condition corresponding to the data stream is satisfied, the activation flag is modified to represent the activation state.

That is to say, after the data stream corresponding to the functional event is activated for a new functional event generated during the vehicle operation process, the traversal time parameter of each node stream may be determined according to the newly activated data stream and the execution duration limitation information of each remaining data stream of resources to be allocated, so as to ensure that the operation of each data stream meets the corresponding execution duration requirement.

In a possible implementation manner, the main control module is configured to:

That is to say, after a certain data stream is activated (for example, after a vehicle-mounted component corresponding to a node stream where any operation node of the data stream is located is started), the data stream may be added to a thread in which the integrated control chip operates, an operation corresponding to a head node in the data stream is executed, the head node is marked as a completed state, and then traversal of each operation node in the data stream is activated, so as to complete a corresponding vehicle event. After the activation state of the data stream is cancelled (for example, after the vehicle-mounted component corresponding to the data stream is closed), the data stream may be removed from the thread.

Optionally, the integrated control chip further includes a storage module for storing a computer program, wherein the main control module implements the operation of the main control module in the integrated control chip by executing the computer program in the storage module.

The storage module may be various media that can store program codes, such as a read-only memory, a random access memory, and the like. The control modules 121 to 126 shown in fig. 2 may also be implemented in the form of software functional units, for example, each control module may be stored in the storage module in the form of a plurality of functional functions, so that the main control module may implement the corresponding operation of the main control module in the integrated control chip by executing the functional functions in the storage module.

Fig. 3 is a flowchart illustrating a control method of an integrated control chip according to an exemplary embodiment, where the method includes:

and S31, circularly and sequentially calling each control module in the integrated control chip according to the determined traversal time parameter of each node flow, and traversing each operation node in the node flow corresponding to the target control module for each called target control module.

The node flow corresponding to each control module is formed by serially connecting operations executed by the control module, and each operation is respectively used as an operation node in the node flow.

S32, for each operation node traversed, determining whether the operation node is in the data stream. The integrated control chip comprises a plurality of operation nodes, wherein one data stream in the integrated control chip corresponds to one event, each data stream is formed by connecting a plurality of operation nodes in series, and each data stream comprises operation nodes in different node streams.

S33, if the operation node is in a data stream and a previous operation node of the operation node in the data stream is in a completed state, executing an operation corresponding to the operation node;

s34, if the operation node is not in the data stream, or the operation node is in the data stream and the previous operation node of the operation node in the data stream is in an unfinished state, traversing the next operation node of the operation node in the node stream corresponding to the target control module;

By adopting the control method of the integrated control chip, when a certain event needs to be realized by utilizing the vehicle-mounted component, a data stream capable of realizing the event is formed by configuring the operation nodes on the node stream corresponding to the control module in the integrated control chip, and when each control module is sequentially and circularly called according to the traversal time parameter of each node stream, the operation nodes in the data stream traverse along with each operation node in the called control module, so as to judge whether to execute the operation nodes in the data stream, and when the operation nodes in the data stream are determined to be executed, the corresponding event is realized. Because the cyclic calling of the control module and the traversal of the operation nodes in the control module are sequentially carried out, corresponding events can be realized by configuring operation points in the data stream, a controller is not required to be independently configured for each vehicle-mounted component on the vehicle, and the development cost of the vehicle is reduced. And the traversal time parameter of each node flow is determined according to the execution time limit information of each data flow, so that the setting of the traversal time parameter of each node flow can meet the execution time limit requirements of all data flows, and the normal response of the vehicle event is ensured.

Optionally, the method further comprises:

In this way, by setting the parameter of the waiting times for each operation node, for each generated set of priority assignment information, the operation quality factor of the integrated control chip can be determined by the waiting times of each operation node under the priority assignment information, so that priority assignment information meeting the requirements can be selected according to the operation quality factor. And finally, setting resource allocation priorities for the plurality of data streams according to the priority allocation information meeting the requirements so as to meet the execution duration requirements of the data streams.

alpha is a constraint factor.

By adopting the control method of the integrated control chip, the execution of the data stream can be ensured to meet the requirement of time limit by planning the resources of the data stream (namely adjusting the traversal time parameter of the node stream related to the data stream), and a controller is not required to be independently configured for each vehicle-mounted component on the vehicle, thereby reducing the development cost of the vehicle.

That is to say, the control goodness coefficient can also be represented by an average value of each control goodness coefficient, that is, the system goodness coefficient, so that the screening efficiency of the resource allocation information is further improved, and the search for the traversal time parameter satisfying the execution time limit information of each data stream is facilitated.

Therefore, by adopting the control method of the integrated control chip, the main control module can monitor the running states of each control module and the operation node corresponding to each control module in real time by setting two control indexes and setting intervals for the good control coefficient and the good system coefficient respectively. That is, the main control module can determine the traversal time parameter of each node flow associated with each data flow according to the execution duration limitation information of the data flow by using the system goodness coefficient and the system goodness coefficient as indexes. In this way, the main control module cyclically and sequentially calls each control module according to the determined traversal time parameter, and traverses each operation node in the node flow corresponding to the target control module aiming at the target control module called each time, so that the operation of each data flow can be ensured to meet the corresponding execution time requirement.

In this way, by setting the operation index of the waiting times for each operation node, the main control module can determine the operation quality coefficient of the integrated control chip through the operation index, and further judge whether the resource allocation priority of the current data stream meets the expectation according to the operation quality coefficient, thereby being beneficial to screening the resource allocation priority of the data stream.
