Fig. 1 is a schematic structural diagram of an automobile according to an embodiment of the present application. As shown in fig. 1, the embodiment of the present application provides an automobile, which uses a qnx+android onboard system, including a QNX operating system 300, a controller area network bus 500 (Controller Area Network, CAN), a cabin entertainment system 400, a micro-control unit 100 (Microcontroller Unit, MCU), and a Telematics BOX 200 (Tbox). The micro control unit 100 is responsible for power related timing, initiating sleep requests, controlling a screen backlight power switch and an audio switch, and the like, and is also responsible for exception handling of a final stage. The controller area network bus 500 is directly connected to the micro control unit 100. The QNX operating system 300 is an on-board instrument system, communicates with the MCU, runs on a 8155 chip, and is used for providing a hupervisor virtual process. 8155 is a general-purpose multifunctional programmable RAM/IO expander, programmable meaning that its function can be changed by the instructions of a computer. The cabin entertainment system 400 employs an android system in communication with the MCU for providing in-car entertainment services, and the cabin entertainment system 400 is started by the Hypervisor virtual process of the QNX operating system 300. The telematics unit 200 communicates with the MCU, also known as an onboard T-BOX, for providing network services to the overall system, and is integrated in the form of a module on a 8155 chip. The remote information processor is a component of the Internet of vehicles system, and the Internet of vehicles system comprises four parts, namely a host, the remote information processor, a mobile phone APP and a background system. Through the structure, the QNX instrument system and android entertainment system on the 8155 chip can be quickly powered off, so that the vehicle can be quickly started and powered off.
Fig. 2 is a flowchart of a method for fast power-on and power-off according to an embodiment of the present application. As shown in fig. 1, an embodiment of the present application provides a method for fast power on and power off, applied to an automobile, where the automobile includes a QNX operating system, a controller area network bus, a cabin entertainment system, a micro control unit, and a telematics unit, the micro control unit communicates with the QNX operating system, the controller area network bus, the cabin entertainment system, and the telematics unit, and the QNX operating system communicates with the cabin entertainment system, the method may include the following steps:
102, receiving a registration key task through a micro control unit under the condition that a control signal is a shutdown signal;
104, judging whether the vehicle-mounted system meets a sleep condition under the condition that the micro control unit does not receive a registration key task within a preset time interval;
In the embodiment of the application, the control signal of the automobile may include a start signal and a shutdown signal. In one example, the control signal of the vehicle is a shutdown signal when the power range of the vehicle is switched from ON to OFF. In another example, when the control signal of the automobile is a start signal, there may be multiple wake-up sources, for example, the entire automobile CAN wake-up, the power gear is switched from OFF to ON, the Tbox wakes up the MCU, and the timing wakes up, which may trigger the start signal.
In the embodiment of the present application, in the case where the control signal is a shutdown signal, the implementation manner of the sleep flow of the vehicle may be as follows:
after receiving the starting signal, the MCU starts to receive key task registration of each controller. In one example, the MCU is directly connected to the CAN bus, and may receive a shutdown signal from the CAN bus that the power state is switched from ON to OFF. In another example, the QNX operating system and the cabin entertainment system may receive the shutdown signal from the SPI of the MCU to monitor whether they are being tasked by the key, and if so, send a message to the MCU to register the key; and if the key task does not exist, sending a message to the MCU to inform the MCU.
Further, the process of receiving the registration of the critical tasks of each controller by the MCU has a timeout mechanism with a preset time interval, and it is required to determine whether the micro control unit receives the registration of the critical tasks within the preset time interval. In one example, the preset time interval may be set according to actual requirements. And in a preset time interval, if the MCU does not receive any controller key task registration, executing a judging program of whether the sleep condition is met. In one example, when the micro control unit receives the registration key task within a preset time interval, the timing is cleared, and the timing is rechemed and judged. For example, the preset time interval is 5 seconds, if the MCU does not receive any controller critical task registration within 5 seconds, executing a judging program of whether the sleep condition is satisfied; if the key task registration is received within 5 seconds, the time is cleared, and the timeout mechanism for 5 seconds is rechemed.
Further, after executing the judging program of whether the sleep condition is met, under the condition that the vehicle-mounted system meets the sleep condition, the CAN, the cabin entertainment system, the QNX operating system, the Tbox and the CAN are sequentially controlled to enter the sleep state so as to control the vehicle-mounted system of the automobile to be quickly powered off. Specifically, the MCU initiates CAN dormancy first, and after CAN dormancy is completed, the MCU sends dormancy information to the QNX operating system. After receiving the dormancy message, the QNX operating system sends the dormancy message to the cabin entertainment system, and the cabin entertainment system enters a dormancy state; when the QNX operating system detects that the cabin entertainment system enters the sleep state, the QNX operating system enters the sleep state and feeds back to the MCU. And after receiving the message that both the QNX operating system and the cabin entertainment system enter the sleep state, the MCU initiates Tbox sleep, and finally the MCU enters a low-energy mode, so that the whole vehicle-mounted system completes the sleep, and the vehicle-mounted system of the automobile is rapidly powered off. Through the technical scheme, the control signal of the automobile is received through the micro control unit; under the condition that the control signal is a shutdown signal, receiving a registration key task through the micro control unit; judging whether the micro control unit receives a key registration task within a preset time interval; judging whether the vehicle-mounted system meets a sleep condition or not under the condition that the micro control unit does not receive a registration key task within a preset time interval; under the condition that the vehicle-mounted system meets the dormancy condition, sequentially controlling the controller local area network bus, the cabin entertainment system, the QNX operating system, the remote information processor and the micro control unit to enter the dormancy state so as to control the vehicle-mounted system of the automobile to be rapidly powered off. The automobile in the application can realize the quick start and the quick shutdown of the automobile through dormancy and awakening dormancy, is favorable to reducing the energy consumption of the system and improves the use experience of a user.
In an embodiment of the present application, the method may further include:
sending a shutdown signal to a cabin entertainment system and a QNX operating system through a micro control unit;
detecting whether a cabin entertainment system and a QNX operating system have critical tasks or not;
in case of critical tasks of the cabin entertainment system and/or the QNX operating system, the critical tasks are registered and sent to the micro control unit.
In the embodiment of the application, after receiving the power-on signal, the power-off signal may be sent to the cabin entertainment system and the QNX operating system through the MCU, and the QNX operating system and the cabin entertainment system may receive the power-off signal from the SPI of the MCU. At the same time, the cabin entertainment system and the QNX operating system each monitor whether the cabin entertainment system and the QNX operating system have critical tasks, namely whether the cabin entertainment system and the QNX operating system have unprocessed tasks, such as OAT upgrading and child monitoring modes and the like. If no critical task exists, the cabin entertainment system and the QNX operating system send a message to the MCU to inform the MCU, respectively. If one of the cabin entertainment system and the QNX operating system has a critical task or both the cabin entertainment system and the QNX operating system have a critical task, a message registration critical task is sent to the MCU every set time. The set time is less than a preset time interval, for example, the preset time interval is 5 seconds, and the set time may be 2 seconds. Therefore, intelligent judgment of the shutdown program can be realized, so that the safety of the whole vehicle system is improved, and the use experience of a user is improved.
In an embodiment of the present application, the method may further include:
in the case that the cabin entertainment system and/or the QNX operating system have critical tasks, performing the critical tasks;
and under the condition that the execution of the critical task is completed, stopping registering the critical task and sending an execution completion signal to the micro control unit.
In the embodiment of the application, if one of the cabin entertainment system and the QNX operating system has a critical task, or the cabin entertainment system and the QNX operating system both have a critical task, the critical task can be continuously executed while a message is sent to the MCU every set time to register the critical task. And under the condition that the execution of the critical task is completed, stopping sending a message to the MCU to register the critical task, and sending an execution completion signal to the MCU. Therefore, the automobile can safely enter the shutdown state, the safety of the whole automobile system is improved, and the use experience of a user is improved.
In this embodiment of the present application, sequentially controlling the controller lan bus, the cabin entertainment system, the QNX operating system, the telematics unit, and the micro control unit to enter a sleep state, so as to control the vehicle-mounted system of the automobile to quickly shut down may include:
a dormancy message is sent to a controller area network bus through a micro control unit so as to control the controller area network bus to dormancy;
under the condition that the controller area network bus finishes dormancy, a dormancy message is sent to the QNX operating system through the micro control unit;
simulating a keyPower key message and sending the key message to a cabin entertainment system under the condition that the QNX operating system receives the dormancy message;
and under the condition that the cabin entertainment system receives the keyPower key message, controlling the cabin entertainment system to enter an STR sleep state.
In the embodiment of the application, after the MCU judges that the condition of entering into dormancy is met, the MCU initiates CAN dormancy, and after the CAN dormancy is completed, the MCU CAN send dormancy information to the QNX operating system in a mode of pulling up GPIO. The QNX operating system receives the sleep message, and may simulate a keyPower key message to send to the cabin entertainment system to notify the cabin entertainment system of sleep. After the cabin entertainment system receives the keyPower key message, all processes of the cabin entertainment system can be suspended to enter a suspend state, so that the whole cabin entertainment system enters an STR dormant state.
In an embodiment of the present application, the method may further include:
under the condition that the cabin entertainment system enters an STR dormant state, controlling the QNX operating system to enter the STR dormant state;
under the condition that the QNX operating system enters a dormant state, sending a dormant message to a remote information processor through a micro control unit;
and under the condition that the remote information processor enters a dormant state, controlling the micro control unit to enter a low-energy consumption mode so as to enable an on-board system of the automobile to be quickly powered off.
In the embodiment of the application, after the QNX operating system detects that the cabin entertainment system enters the STR sleep state, the QNX operating system starts to enter the STR sleep state. After the QNX operating system enters STR, 8155 chip feeds back the sleep completion message of both cabin entertainment system and QNX operating system to MCU through PMIC IO port. Because the Tbox is the last controller disconnected from the server except the MCU, after the MCU receives a message that both the cabin entertainment system and the QNX operating system enter the STR sleep state, the MCU starts to initiate Tbox sleep. After the Tbox enters a dormant state, the MCU enters a low-power consumption mode, so that the whole vehicle-mounted system completes STR dormancy, and the vehicle-mounted system of the vehicle is rapidly powered off.
In an embodiment of the present application, the method may further include:
under the condition that the control signal is a starting signal, controlling the micro control unit to execute a power-on flow and sending a wake-up message to the remote information processor and the QNX operating system;
under the condition that the remote information processor receives the wake-up message, controlling the remote information processor to recover to a normal working state;
under the condition that the QNX operating system receives the wake-up message, controlling the QNX operating system to recover to a normal working state;
under the condition that the QNX operating system is restored to a normal working state, controlling the QNX operating system to send a wake-up message to the cabin entertainment system through a virtual key event;
and under the condition that the cabin entertainment system receives the wake-up message, controlling the cabin entertainment system to recover to a normal working state from the STR mode so as to control the on-board system of the automobile to start.
In this embodiment of the present application, when the control signal of the automobile is a startup signal, there may be multiple wake-up sources, for example, the entire automobile CAN wake-up ON network, the power gear is switched from OFF to ON, the Tbox wakes up the MCU, and the timing wakes up, where the above wake-up sources CAN trigger the startup signal.
Specifically, under the condition that the control signal of the automobile is a starting signal, the automobile machine system can realize quick starting in the following manner:
firstly, the MCU executes the power-on flow of some peripheral devices and screens, and sends a wake-up message to the Tbox and QNX operating systems by pulling the GPIO high. And after receiving the wake-up message, the Tbox resumes the relevant process or restarts the relevant process to complete normal network supply and work. After the QNX operating system receives the wake-up message through the GPIO, the interrupt triggers the QNX operating system Qcore and resumes the execution of the Resume process from STR mode. In one example, the system can be quickly awakened to restore to the state before Suspend by enabling data in DDR, so that quick response is realized to speed up the starting speed of the system. Furthermore, the whole QNX operating system re-activates the resources, the state and the like stored before entering the STR dormant state, the PMIC indicates that the pins are pulled down, and the SOC resumes to enter the normal working state. Further, the QNX operating system notifies the cabin entertainment to restore to a normal working state through a virtual key IO event. In the event that a wake-up message is received, the cabin entertainment system likewise resumes the execution of the Resume process from STR mode.
Therefore, through the process, the QNX operating system can realize quick recovery starting within 2 seconds, and the cabin entertainment system can realize quick recovery starting within 3 seconds, so that the whole automobile system of the automobile can be quickly started and normally works within 5 seconds, and the quick starting and starting of the whole automobile are realized.
In an embodiment of the present application, the power-on signal may include at least one of the following:
a starting signal sent by a local area network bus of the whole vehicle controller;
a power supply is switched to a starting signal generated by a starting gear;
the remote information processor wakes up a starting signal generated by the micro control unit;
and (5) a startup signal sent at fixed time.
In this embodiment of the present application, when the control signal of the automobile is a startup signal, there may be multiple wake-up sources, for example, the entire automobile CAN wake-up ON network, the power gear is switched from OFF to ON, the Tbox wakes up the MCU, and the timing wakes up, where all the four wake-up sources may trigger the startup signal. In one example, any one of conditions of CAN network wake-up, power gear switching from OFF to ON, tbox wake-up MCU and timing wake-up is satisfied, namely, a start-up signal is triggered, and the vehicle system is controlled to execute a start-up program. Therefore, a plurality of wake-up sources coexist, the user requirements can be better met, and the use experience of the user is improved.
