Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below with reference to the accompanying drawings.

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 achieve low power operation of the controller, the sleep unit in the application layer may choose to generate an application layer sleep instruction, an underlying sleep instruction, and a control unit sleep instruction at appropriate times, and send the application layer sleep instruction, the underlying sleep instruction, and the control unit sleep instruction to the application layer.

The problems with this are: when the application layer, the bottom layer and the control unit enter the dormant state, when bus network signals corresponding to the application layer appear for a plurality of times within a period of time, the application layer, the bottom layer and the control unit can wake up for a plurality of times, and then the vehicle controller is switched between the dormant state and the wake-up state for a plurality of times, so that the service life of the electronic devices of the vehicle controller is influenced.

Therefore, to improve the dormancy efficiency of vehicle control and extend the service life of vehicle electronics, it is desirable to dormancy the network links corresponding to the application layer and the underlying layer.

As shown in fig. 1, the method of the present embodiment includes:

step 101, acquiring a network signal in a vehicle and determining a vanishing time point corresponding to the network signal.

In this step, the network signal refers to a signal capable of indicating that the vehicle is operating in a high power consumption state, and for example, the network signal may be a LIN (Local Interconnect Network, local bus) signal and a CAN (Controller Area Network ) signal in an AUTOSAR (Automotive Open System Architecture, automobile open system architecture).

The vanishing time point refers to a time point when the network signal completes transmission. Specifically, an application layer in the vehicle controller can send a query request for querying a network signal to a bottom layer in real time, and the bottom layer obtains a vanishing time point corresponding to the network signal from the application layer according to the query request and sends the vanishing time point to the application layer.

In this way, the vanishing time point can provide a starting time reference for a subsequent timing process, and vehicle dormancy directly at the vanishing time point of the network signal is avoided.

And 102, timing the vanishing time point as a starting time, and determining an ending time according to the network signal.

In this step, in order to avoid the vehicle dormancy directly at the vanishing point of the network signal, the end time of the timing process is determined according to whether a new network signal exists, and a timing basis is provided for the determination of the subsequent timing time.

The start time refers to a timing start time point of the timing process, and the end time refers to a timing end time point of the timing process. For example, the start time may be 10 minutes 30 seconds at the stop lamp signal disappearing time point, and the end time may be 21 minutes 30 seconds at the right rear turn lamp signal acquiring time point 10.

In this way, the determination of the start time and the end time provides a data basis for the determination of the subsequent timing time.

Step 103, determining a timing time through the starting time and the ending time.

In this step, the timer time refers to the time between the vanishing time point of the network signal and the receiving time point of the new network signal, for example, the time between the vanishing time point of the brake light signal and the acquisition time point of the right rear turn light signal. For example, the start time may be a brake light signal disappearing time point 10 points for 20 minutes 30 seconds, the end time may be a right rear turn light signal acquiring time point 10 points for 21 minutes 30 seconds, and the time-counting time determined according to the start time and the end time may be 1 minute.

In this way, the determination of the timing time provides a comparison basis for the comparison of the subsequent and judgment times.

And 104, comparing the timing time with a preset judging time to obtain a comparison result.

In this step, the judgment time refers to a time at which a sleep instruction can be generated, for example, a time between a stop lamp signal disappearing time point and a right rear turn lamp signal acquiring time point is 1min, and the judgment time is 2min, so that the comparison result is that the time 1min is less than the judgment time 2min.

Therefore, different comparison results correspond to different dormancy instructions, and a judgment basis can be provided for the subsequent generation of the dormancy instructions according to the comparison results of the timing time and the judgment time.

And 105, generating a dormancy instruction according to the comparison result, and sending the dormancy instruction to a network link where the network signal is located, so that the network link enters a dormancy state.

In this step, the sleep instruction refers to an instruction capable of causing the network link to enter a sleep state, for example, the sleep instruction may be a CAN bus sleep instruction sent by the application layer to the bottom layer after 2 minutes. Thus, delay generation of the dormancy instruction is realized, and the awakening of the dormant vehicle by the network signal in the judging time is avoided, so that the awakening times of the dormant vehicle are reduced, and the dormancy efficiency of the vehicle is improved.

Therefore, delay generation of the dormancy instruction is realized through comparison of the timing time and the judging time, so that awakening of the dormant vehicle by the network signal in the judging time is avoided, the awakening times of the dormant vehicle are reduced, and the dormancy efficiency of the vehicle is improved.

According to the scheme, the timing time is determined according to the vanishing time point of the network signal, the timing time is compared with the preset judging time, and the dormancy instruction is generated and sent according to the comparison result, so that the vehicle dormancy is prevented from being directly carried out at the vanishing time point of the network signal, and the delay generation of the dormancy instruction is realized through the comparison of the timing time and the judging time, so that the network signal appearing in the judging time is prevented from waking up the dormant vehicle, the number of times of waking up the dormant vehicle is reduced, and the dormancy efficiency of the vehicle is improved.

In some embodiments, the network signal comprises: bus network signals and local network signals;

the acquiring the network signal in the vehicle and determining the vanishing time point corresponding to the network signal comprises the following steps:

determining the vanishing time point according to the plurality of first end time points and the plurality of second end time points.

In the above scheme, the bus network signal refers to a signal transmitted in a network link connected to the application layer, and the local network signal refers to a signal transmitted in a network link connected to the bottom layer. The first end time point refers to a time point when a single network signal in the bus network signal ends transmission, and the second end time point refers to a time point when a single network signal in the local network signal ends transmission.

Specifically, the bus network signal may be a plurality of network signals, and when there are a plurality of network signals in the network link while being transmitted, the first end time point of each of the plurality of network signals may be different, for example, the bus network signal may be a right rear turn signal output signal, a brake light output signal, and a rear fog light switch signal that are simultaneously transmitted in the network link, so the plurality of first end time points may be a first end time point 10 point 22 minutes 30 seconds of the right rear turn signal output signal, a first end time point 10 point 20 minutes 30 seconds of the brake light output signal, and a first end time point 10 point 21 minutes 30 seconds of the rear fog light switch signal.

The local network signal may be a plurality of network signals, and when the plurality of network signals are present in the network link while being transmitted, a second end time point of each of the plurality of network signals may be different, for example, the local network signal may be a left side mirror vertical adjustment motor signal, a left side mirror adjustment angle sensor signal, and a right side mirror adjustment angle sensor signal that are simultaneously transmitted in the network link, so the plurality of second end time points may be a second end time point 10 of the left side mirror vertical adjustment motor signal for 23 minutes 30 seconds, a second end time point 10 of the left side mirror adjustment angle sensor signal for 26 minutes 45 seconds, and a second end time point 10 of the right side mirror adjustment angle sensor signal for 26 minutes 30 seconds.

By the scheme, a data basis is provided for the determination of the subsequent vanishing time point.

In some embodiments, the vanishing time point comprises: bus vanishing time point and local vanishing time point;

said determining said vanishing time point from said first end time point and said second end time point comprises:

the determining the vanishing time point according to the plurality of first end time points and the plurality of second end time points includes:

Sequencing the plurality of first ending time points according to the sequence from the early to the late to obtain a first sequencing result;

taking the latest first ending time point in the first sequencing result as the bus vanishing time point;

and taking the latest second ending time point in the second sorting result as the local vanishing time point.

In the above-described scheme, in order to determine the latest end time point of the bus network signal and the local network signal, the end times corresponding to the bus network signal and the local network signal are ordered in the order from early to finish, and the latest end time point in the ordering result is taken as the vanishing time point.

The bus vanishing time point refers to a vanishing time point corresponding to the bus network signal, and the local vanishing time point refers to a vanishing time point corresponding to the local network signal.

The first ordering result refers to ordering results of the plurality of first end time points ordered in the order from the early to the late, for example, the plurality of first end time points may be 10 points 21 minutes 30 seconds, 10 points 22 minutes 30 seconds, 10 points 20 minutes 30 seconds, then the first ordering result may be 10 points 20 minutes 30 seconds, 10 points 21 minutes 30 seconds, 10 points 22 minutes 30 seconds, and the bus vanishing time point may be 10 points 22 minutes 30 seconds.

The second ordering result refers to ordering results obtained by ordering the plurality of second end time points in the order from the morning to the evening, for example, the plurality of second end time points may be 10 points 24 minutes 30 seconds, 10 points 23 minutes 30 seconds, 10 points 26 minutes 30 seconds, then the second ordering result may be 10 points 23 minutes 30 seconds, 10 points 26 minutes 45 seconds, 10 points 26 minutes 30 seconds, and the local vanishing time point may be 10 points 26 minutes 45 seconds.

By the scheme, the bus starting time and the local starting time are provided for the subsequent timing process.

In some embodiments, the timing the vanishing time point as a start time and determining an end time from the network signal includes:

the bus vanishing time point is used as bus starting time to time, and bus ending time is determined according to the bus network signal;

and taking the local vanishing time point as a local starting time to time, and determining a local ending time according to the local network signal.

In the above scheme, timing is performed according to the bus vanishing time point and the local vanishing time point as starting times respectively, and a query request for querying a network signal is sent in real time to a network link through an application layer, the network link obtains state information of whether the network signal exists according to the query request, and sends the state information to the application layer, and the application layer determines the ending time according to the state information.

Specifically, the bus end time refers to an end time in a timing process corresponding to the bus start time, and the local end time refers to an end time in a timing process corresponding to the local start time. For example, the bus start time may be 10 minutes 30 seconds of the stop lamp signal vanishing time point, and the bus end time may be 21 minutes 30 seconds of the right rear turn lamp signal acquisition time point 10. The local start time may be 10 minutes 30 seconds of the right side mirror adjustment angle sensor signal vanishing time point, and the local end time may be 10 minutes 45 seconds of the left side mirror adjustment angle sensor signal acquisition time point.

By the scheme, the bus ending time and the local ending time are provided for the subsequent timing process.

In some embodiments, the timing time comprises: bus timing time and local timing time; determining a timing time from the start time and the end time, comprising:

judging whether a new bus network signal exists after the bus starting time to obtain a first judging result;

in response to determining that the first judgment result is that a new bus network signal exists, recording bus acquisition time of the new bus network signal;

The bus acquisition time is used as bus ending time corresponding to the bus starting time, and the bus timing time is obtained;

judging whether a new local network signal exists after the local start time to obtain a second judging result;

responsive to determining that the second determination result is that a new local network signal exists, recording a local acquisition time of the new local network signal;

and taking the local acquisition time as a local ending time corresponding to the bus starting time to obtain the local timing time.

In the above scheme, the application layer determines the end time of the timing according to whether a new network signal exists in the state information, and when the new network signal exists, the application layer ends the timing.

Specifically, the application layer may start the sleep monitor timer to count according to the vanishing time point as the start time, and when the application layer determines that a new network signal exists according to the state information, the sleep monitor timer counts up and records the end time, and counts up the count time according to the time between the start time and the end time.

For example, the bus start time may be 10 minutes and 30 seconds from the stop lamp signal disappearance time point, and after the bus start time, a new bus network signal appears, and then the acquisition time of the right back turn lamp signal is 10 minutes and 30 seconds as the bus end time. The local start time may be a point of time of 10 minutes and 30 seconds when the right side rearview mirror adjustment angle sensor signal disappears, after the local start time, a new local network signal appears to obtain the left side rearview mirror adjustment angle sensor signal, and then the point of time of 10 minutes and 45 seconds when the left side rearview mirror adjustment angle sensor signal obtains is taken as the local end time.

It will be appreciated that the timing of the sleep monitor timer is cleared when a new network signal occurs within the decision time.

Through the scheme, a data basis is provided for comparison of the follow-up timing time and the judgment time.

In some embodiments, the determining the time includes: bus judgment time and local judgment time; comparing the timing time with a preset judging time to obtain a comparison result, wherein the comparing comprises the following steps:

comparing the bus timing time with preset bus judging time to obtain a bus comparison result;

and comparing the local timing time with a preset local judging time to obtain a local comparison result.

In the above-described aspect, the bus determination time refers to a time at which the bus sleep instruction can be generated, and the local determination time refers to a time at which the local sleep instruction can be generated. For example, the time between the disappearance time point of the brake light signal of the bus network signal and the acquisition time point of the right rear turn light signal of the bus network signal is 1min, the bus judgment time is 2min, and the bus comparison result is that the bus timing time is smaller than the bus judgment time.

According to the scheme, different comparison results correspond to different dormancy instructions, so that a judgment basis can be provided for the subsequent generation of the dormancy instructions according to the comparison results of the timing time and the judgment time.

In some embodiments, the generating a sleep instruction according to the comparison result, and sending the sleep instruction to a network link where the network signal is located, includes:

generating a bus network dormancy instruction and sending the bus network dormancy instruction to a network link where the bus network signal is located in response to determining that the bus comparison result is that the bus timing time is greater than or equal to the bus judgment time;

generating a local network dormancy instruction and sending the local network dormancy instruction to the local network in response to the determination that the local comparison result is that the local timing time is greater than or equal to the local judgment time;

and acquiring a sending time point for sending the local network dormancy instruction, taking the sending time point as a waiting starting time point, generating a control unit dormancy instruction after preset waiting time, and sending the control unit dormancy instruction to a control unit so as to enable the control unit to enter a dormancy state, wherein the control unit is used for controlling the action of a vehicle.

In the above scheme, the bus sleep instruction refers to an instruction capable of making the bus network enter a sleep state, and the local sleep instruction refers to an instruction capable of making the local network enter a sleep state.

Specifically, the control unit refers to a unit for controlling the motion of the vehicle, the control unit is connected with the bottom layer, and the application layer can realize dormancy and awakening of the control unit through the bottom layer.

The present embodiment may further include:

responding to the bus comparison result that the bus timing time is smaller than the bus judgment time, and acquiring a bus vanishing time point corresponding to the new bus network signal;

taking the bus vanishing time point corresponding to the new bus network signal as a new bus starting time for timing, and obtaining a new bus timing time according to the new bus network signal;

responding to the determination that the local comparison result is that the local timing time is smaller than the local judging time, and acquiring a local vanishing time point corresponding to the new local network signal;

and taking the local vanishing time point corresponding to the new local network signal as a new local starting time for timing, and obtaining a new local timing time according to the new local network signal.

Specifically, when the bus timing time is more than or equal to the bus judging time of 2min, generating a bus network dormancy instruction by using a bus network dormancy function and sending the bus network dormancy instruction to a network link where the bus network signal is located; however, when the bus timing time 1min is less than the bus judging time 2min, since the bus timing time 1min is determined according to the new bus network signal, that is, the new bus network signal appears in the bus judging time, if the network link where the bus network signal is located enters the sleep state at the bus vanishing time point, the new bus network signal wakes up the network link in the sleep state, and the wake-up times of the dormant network link are increased.

In this embodiment, the network link where the bus network link is located enters the sleep state after the bus judgment time, so when a new bus network signal occurs, the network link is not in the sleep state, so that the wake-up of the dormant network link in the bus judgment time is avoided, and the wake-up times of the dormant network link are reduced.

When a new bus network signal exists in the network link, the new bus timing time can be obtained by taking the bus vanishing time point corresponding to the new bus network signal as the new bus starting time to time, and a dormancy judgment basis is provided for dormancy of the network link where the subsequent bus network signal is located.

When the local timing time 2min is greater than or equal to the local judging time 1min, generating a local network dormancy instruction by utilizing a local network dormancy function and sending the local network dormancy instruction to a network link where the local network signal is located; however, when the local time 0.5min is less than the local judgment time 1min, the local time 0.5min is determined according to the new local network signal, that is, the new local network signal appears in the local judgment time, if the network link where the local network signal is located enters the dormant state at the local vanishing time point, the new local network signal wakes up the network link in the dormant state, and the number of wake-up times of the dormant network link is increased.

In this embodiment, the network link where the local network link is located enters the sleep state after the local judgment time, so when a new local network signal occurs, the network link is not in the sleep state, and therefore, the wake-up of the dormant network link in the local judgment time is avoided.

When a new local network signal exists in the network link, the local vanishing time point corresponding to the new local network signal can be used as the new local starting time to count time, so as to obtain the new local timing time, and a dormancy judgment basis is provided for dormancy of the network link where the subsequent local network signal is located.

By the scheme, delay generation of the dormancy instruction is realized, and the phenomenon that the network signal appears in the judging time wakes the dormant vehicle is avoided, so that the number of times of waking the dormant vehicle is reduced, and the dormancy efficiency of the vehicle is improved.

In some embodiments, the method further comprises:

in response to determining that a new local network signal or a new bus network signal is acquired after the wait start time point, generating a bus wake-up signal and a local wake-up signal and sending the bus wake-up signal and the local wake-up signal to the bus network and the local network, respectively.

In the above-described scheme, the bus wakeup signal refers to a signal capable of waking up the bus network that has entered the sleep state, and the local wakeup signal refers to a signal capable of waking up the local network that has entered the sleep state. The wake-up signal may be generated by a wake-up function in the application layer.

Specifically, after waiting for the start time point, the bus network and the local network have already entered a sleep state, and because the application layer sends a query signal for querying a local network signal or a bus network signal to a network link including the bus network and the local network in real time, the network link obtains the local network signal or state information of the bus network signal according to the query signal, and sends the state information to the application layer, and when the state information includes a new local network signal or a new bus network signal, the application layer generates a bus wake-up signal and a local wake-up signal. In this way, through the delayed dormancy of the bus network and the local network, the wake-up of the network link by the new bus network signal and the local network signal in the delayed dormancy process is avoided.

By the aid of the scheme, the awakening times of the dormant vehicle are reduced, and the dormant efficiency of the vehicle is improved.

It should be noted that, the method of the embodiments of the present application may be performed by a single device, for example, a computer or a server.

In step 1, the application layer always detects whether a network maintaining source (corresponding to a bus network signal in the embodiment of the present application) exists, if the network maintaining source exists all the time, the network is maintained all the time (corresponding to a network link in the embodiment of the present application), if the last network maintaining source disappears, the timing is started for 2min (corresponding to the bus judgment time in the embodiment of the present application), and if a new network maintaining source appears within 2min, the network is continuously maintained and the timer is cleared.

And 2, if the 2min timing time is up, and no new network keeping source exists, the application layer sends a CAN (Controller Area Network ) dormancy instruction to the bottom layer, and then LIN (Local Interconnect Network, local Internet) dormancy waits to start 1min (corresponding to the local judgment time in the embodiment of the application) timing.

And 3, if a new local maintenance source (corresponding to a local network signal in the embodiment of the application) appears within 1min, continuing to keep local wakeup, if the 1min timing time is up, and if no new local maintenance source exists, the application layer sends an LIN sleep instruction to the bottom layer, and then waits for 3s (corresponding to the waiting time in the embodiment of the application), and the application layer sends the sleep instruction to the MCU (Micro-controller Unit) to enable the MCU to enter a low power consumption mode.

And step 4, if a new wake-up source (corresponding to the network signal in the embodiment of the application) exists during the waiting period, the application layer immediately sends a wake-up network instruction to wake up the network.
