Control methods and intelligent cockpit systems

Abstract

This application provides a control method and an intelligent cockpit system. When the microcontroller detects that the vehicle signals meet the conditions for suspending to memory, it sends a shutdown command to the application processing system. Upon successful shutdown of the application processing system, it controls its cold start, freeing up memory space before the application processing system enters the suspend-to-memory mode. After a successful cold start, the microcontroller sends a command to the application processing system to enter the suspend-to-memory mode, causing the application processing system to begin entering this mode. Upon receiving a successful entry message from the application processing system, the microcontroller powers down the peripherals of the intelligent cockpit system and puts the intelligent cockpit system into sleep mode. This disconnects power to devices other than memory, preventing applications from occupying hardware resources and causing the intelligent cockpit system to fail to enter the suspend-to-memory mode, thus further improving the success rate of the intelligent cockpit system successfully entering this mode.

[0089] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below with reference to the drawings in the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0090] As described in the background, the intelligent cockpit system supporting the suspend to RAM (STR) function realizes fast system startup and recovery, greatly shortens the system function available time, and improves the user experience.

[0091] However, due to the problems such as multiple functions of the intelligent cockpit system and complex use scenarios, the implementation of the system STR function is strongly dependent on application adaptation, and due to the basic principles of the operating system and the kernel, it is necessary to ensure that there is no application occupying hardware resources when successfully entering the suspend to memory mode, so it is required that the applications occupying hardware resources must be adapted to reduce the problem of entering the suspend to memory mode.

[0092] The present application provides a control method of an intelligent cockpit system. Before an application processing system enters a suspend to memory mode, the application processing system is cold started to release memory space, so that the memory can store the running state information of the application processing system when entering the suspend to memory mode, thereby improving the success rate of entering the suspend to memory mode. Then, after the cold start of the application processing system is successful, an instruction of entering the suspend to memory mode is sent to the application processing system, so that the application processing system starts to enter the suspend to memory mode, and after the application processing system successfully enters the suspend to memory mode, the peripherals of the intelligent cockpit system are powered off and enter a sleep mode, so that other devices other than the memory are powered off, thereby avoiding the problem that the application occupies hardware resources and causes the intelligent cockpit system to fail to enter the suspend to memory mode, and further improving the success rate of the intelligent cockpit system to successfully enter the suspend to memory mode.

[0093] The technical solutions of the present application will be described in detail below with reference to the drawings in the present application. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in some embodiments.

[0094] Figure 1A flowchart of a control method of an intelligent cockpit system is shown. As shown in the figure, the micro-control system is the execution subject, and the method of the embodiment can include the following steps: Figure 1

[0095] S101, when the micro-control system monitors that the vehicle signal meets the entering suspension to memory condition, the micro-control system sends a shutdown instruction to the application processing system, so that the application processing system performs shutdown processing.

[0096] In the embodiment, the intelligent cockpit system includes a micro-control system (VP / MCU) and an application processing system (AP). The micro-control system can monitor the vehicle signal, determine whether the vehicle signal meets the entering suspension to memory condition (STR condition), and send a shutdown instruction to the application processing system when the vehicle signal meets the entering suspension to memory condition. The application processing system performs shutdown processing after receiving the shutdown instruction.

[0097] In actual application, when the vehicle signal meets the entering suspension to memory condition, the micro-control system can also control the power state of the intelligent cockpit system to migrate. For example, the micro-control system monitors the vehicle signal and determines whether the vehicle signal meets the suspension to memory condition. If so, the power state of the cockpit system is controlled to migrate to the power state corresponding to the sleep mode, i.e., the power state of the intelligent cockpit system is controlled to migrate to the power state corresponding to the suspension to memory mode.

[0098] In the embodiment, the vehicle signal meeting the entering suspension to memory condition includes one or more conditions such as the temperature being lower than a preset temperature and the remaining power being lower than a preset power. The preset temperature and the preset power can be determined according to actual conditions and are not limited herein.

[0099] S102, after the micro-control system monitors that the application processing system has been successfully shut down, the micro-control system controls the application processing system to perform cold start.

[0100] In the embodiment, the micro-control system can send an inquiry message to the application processing system. If a response message to the inquiry message is received within a preset time, it indicates that the application processing system has not been successfully shut down. If no response message to the inquiry message is received within the preset time, it indicates that the application processing system has been successfully shut down. The preset time can be determined according to actual conditions.

[0101] After the micro-control system monitors that the application processing system has been successfully shut down, the micro-control system controls the application processing system to perform cold start. The cold start can be understood as the application processing system being started again after being shut down. The cold start of the application processing system causes the information in the memory to be cleared, thereby releasing the memory space.

[0102] S103, after the micro-control system receives a cold start success message sent by the application processing system, the micro-control system sends an entering suspension to memory instruction to the application processing system, so that the application processing system enters the suspension to memory mode.​

[0103] In this embodiment, the application processing system can send a cold start success message to the micro control system after the cold start is successful. The micro control system sends a suspend to memory instruction to the application processing system after the cold start of the application processing system is successful. The application processing system starts to enter the suspend to memory mode after receiving the suspend to memory instruction, for example, the application processing system can notify the application that has registered the suspend to memory notification mechanism that the application processing system is about to enter the suspend to memory mode, so that the application that has registered the suspend to memory notification mechanism can enter the suspend to memory processing, and the suspend to memory processing includes saving the running state to the memory, for example.

[0104] It should be noted that the cold start mentioned in the present application can be understood as starting the cold start, and the cold start can be completed after a certain period of time, that is, the cold start is successful.

[0105] In some embodiments, the micro controller sends a suspend to memory instruction to the application processing system after receiving the cold start success message sent by the application processing system, and delays for a preset time, thereby improving the effectiveness of receiving the cold start success message.

[0106] S104, after the micro control system receives the enter success message sent by the application processing system, the peripherals of the intelligent cockpit system are powered off, and the intelligent cockpit system is controlled to enter the sleep mode (power off).

[0107] In this embodiment, the application processing system can send an enter success message to the micro control system after successfully entering the suspend to memory mode. The micro control system receives the enter success message sent by the application processing system, and controls the peripherals of the intelligent cockpit system to be powered off, which can include Bluetooth, sound, camera, etc. At the same time, the micro control system also controls the intelligent cockpit system to enter the sleep mode (power off) to save power.

[0108] It should be noted that the enter suspend to memory mode mentioned in the present application can be understood as starting the enter suspend to memory mode, and the enter suspend to memory mode can be successfully entered after a certain period of time.

[0109] In some embodiments, the micro control system receives the first enter success message sent by the intelligent cockpit system, controls the peripherals of the intelligent cockpit system to be powered off, and controls the intelligent cockpit system to enter the sleep mode.

[0110] In some embodiments, the micro-control system sends a shutdown instruction to the application processing system after monitoring that the application processing system fails to enter the suspend-to-ram mode for the first time, and controls the peripherals of the intelligent cockpit system to power off and controls the intelligent cockpit system to enter the sleep mode after receiving the second-time entry success message sent by the application processing system. It can be understood that after the micro-control system monitors that the application processing system fails to enter the suspend-to-ram mode for the second time, steps S101-S103 are re-executed to again attempt the application processing system to enter the suspend-to-ram mode for the second time, and the peripherals of the intelligent cockpit system are controlled to power off and the intelligent cockpit system is controlled to enter the sleep mode after receiving the second-time entry success message sent by the application processing system. If it is monitored that the application processing system fails to enter the suspend-to-ram mode for the second time, a shutdown instruction is sent to the application processing system so that the application processing system performs shutdown processing.

[0111] The control method of the intelligent cockpit system provided in the present application releases the memory space by performing a cold start operation on the application processing system before the application processing system enters the suspend-to-ram mode, so that the memory can store the running state information of the application processing system when entering the suspend-to-ram mode, thereby improving the success rate of entering the suspend-to-ram mode. When the application processing system successfully enters the suspend-to-ram mode, the peripherals of the intelligent cockpit system are controlled to power off and the intelligent cockpit system enters the sleep mode, so that other devices other than the memory are powered off, thereby avoiding the problem that the application occupies hardware resources to cause the intelligent cockpit system to fail to enter the suspend-to-ram mode, and further improving the success rate of the intelligent cockpit system to successfully enter the suspend-to-ram mode.

[0112] Figure 2 A flowchart of a control method of an intelligent cockpit system is shown. As shown in Figure 2 The method of the present embodiment can include the following steps:

[0113] S201, when the micro-control system monitors that the vehicle signal meets the suspend-to-ram condition, the micro-control system sends a shutdown instruction to the application processing system to make the application processing system perform shutdown processing.

[0114] S202, after the micro-control system monitors that the application processing system shuts down successfully, the micro-control system controls the application processing system to perform a cold start.

[0115] S203, after the micro-control system receives the cold start success message sent by the application processing system, the micro-control system sends an enter suspend-to-ram instruction to the application processing system to make the application processing system enter the suspend-to-ram mode.

[0116] S204, after the micro-control system receives the enter success message sent by the application processing system, the micro-control system controls the peripherals of the intelligent cockpit system to power off and controls the intelligent cockpit system to enter the sleep mode.

[0117] S205, when the micro-control system monitors that the vehicle signal meets the exit suspension to memory condition, the intelligent cockpit system is controlled to enter the normal mode (Normal mode) and the peripherals of the intelligent cockpit system are powered on.

[0118] In this embodiment, after the application processing system enters the suspension to memory mode, the micro-control system can still monitor the vehicle signal to determine whether the vehicle signal meets the exit suspension to memory condition. If yes, the intelligent cockpit system is controlled to enter the vehicle mode and the peripherals of the intelligent cockpit system are powered on.

[0119] In some embodiments, the vehicle signal meeting the suspension to memory condition includes one or more conditions such as the temperature being higher than or equal to a preset temperature, the remaining power being higher than or equal to a preset power, etc.

[0120] In this embodiment, when the vehicle signal meets the exit suspension to memory condition, the micro-control system can also control the power state of the intelligent cockpit system to migrate.

[0121] S206, the micro-control system sends an exit suspension to memory instruction to the application processing system, so that the application processing system exits the suspension to memory mode.

[0122] S207, after the micro-control system monitors that the application processing system exits the suspension to memory mode successfully, the intelligent cockpit system exits the suspension to memory mode and recovers to the working state.

[0123] In this embodiment, after the application processing system successfully exits the suspension to memory mode, the application processing system can send an exit success message to the micro-control system. If the micro-control system monitors the exit success message within a preset time, it indicates that the intelligent cockpit system exits the suspension to memory mode and successfully recovers to the working state. If the micro-control system does not monitor the exit success message within the preset time, it indicates that the intelligent cockpit system fails to exit the suspension to memory mode, and step S208 can be performed.

[0124] S208, after the micro-control system monitors that the application processing system fails to exit the suspension to memory mode, the application processing system is reset.

[0125] The control method of the intelligent cockpit system provided in the application sends an exit suspension to memory instruction to the application processing system when the vehicle signal meets the exit suspension to memory condition, so that the application processing system exits the suspension to memory mode, and determines that the intelligent cockpit system exits the suspension to memory mode after monitoring that the application processing system exits the suspension to memory mode successfully.

[0126] Figure 3 A flowchart of a control method of an intelligent cockpit system is shown. As shown in FIG. 1, the control method includes the following steps. Figure 3As shown, the method of the embodiment can include the following steps with the application processing system as the execution subject.

[0127] S301, the application processing system receives the shutdown instruction sent by the micro control system and performs shutdown processing.

[0128] The shutdown instruction is sent by the micro control system when it monitors that the vehicle signal meets the entering suspend to memory condition.

[0129] S302, the application processing system receives the cold start instruction sent by the micro control system and performs cold start, and sends a cold start success message to the micro control system after the cold start is successful.

[0130] The cold start instruction is sent by the micro control system after it monitors that the application processing system is successfully shut down.

[0131] S303, the application processing system receives the entering suspend to memory instruction sent by the micro control system, enters the suspend to memory mode, and sends an entering success message to the micro control system after successfully entering the suspend to memory mode, so that the micro control system controls the peripherals of the intelligent cockpit system to power off and controls the intelligent cockpit system to enter the sleep mode.

[0132] After the application processing system receives the entering suspend to memory instruction sent by the micro control system, it starts to enter the suspend to memory mode, and after a certain time, successfully enters the suspend to memory mode, it sends an entering success message to the micro control system. After the micro control system receives the entering success message, it controls the peripherals of the intelligent cockpit system to power off and controls the intelligent cockpit system to enter the sleep mode.

[0133] In some embodiments, the micro control system sends an exiting suspend to memory instruction to the application processing system when the vehicle signal meets the exiting suspend to memory condition. After the application processing system receives the exiting suspend to memory instruction, it exits the suspend to memory mode, so that the micro control system monitors that the application processing system successfully exits the suspend to memory mode, and restores the working state of the intelligent cockpit system, and monitors that the application processing system fails to exit the suspend to memory mode, and performs reset processing on the application processing system.

[0134] The control method of the intelligent cockpit system provided in the application releases memory space after the application processing system receives a cold start, so that the memory can store the running state information of the application processing system when the application processing system enters the suspend-to-ram mode, thereby improving the success rate of entering the suspend-to-ram mode. When the application processing system successfully enters the suspend-to-ram mode, the micro control system controls the peripherals of the intelligent cockpit system to power off and enter the sleep mode, so that other devices other than the memory are powered off, thereby avoiding the problem that the application occupies hardware resources and causes the intelligent cockpit system to fail to enter the suspend-to-ram mode, and further improving the success rate of the intelligent cockpit system successfully entering the suspend-to-ram mode.

[0135] The embodiment of the application provides an intelligent cockpit system, comprising a micro control system and an application processing system.

For example, the entertainment system can generate a marker after successfully entering the hibernation-to-memory mode, and the marker is used to indicate that the entertainment system has successfully entered the hibernation-to-memory mode; the instrument system can determine that the entertainment system has successfully entered the hibernation-to-memory mode after monitoring the marker.

[0145] In other embodiments, the micro-control system sends an exit-hibernation-to-memory instruction to the instrument system when monitoring that the whole-vehicle signal meets the exit-hibernation-to-memory condition; the instrument system sends a second event to the entertainment system after receiving the exit-hibernation-to-memory instruction; the entertainment system exits the hibernation-to-memory mode after receiving the second event; the instrument system controls the system to exit the hibernation-to-memory mode after monitoring that the entertainment system has successfully exited the hibernation-to-memory mode; the micro-control system controls the intelligent cockpit system to exit the hibernation-to-memory mode and restore the working state when monitoring that the instrument system has successfully exited the hibernation-to-memory mode; and the micro-control system performs reset processing on the application processing system when monitoring that the instrument system fails to exit the hibernation-to-memory mode.

[0146] In the embodiment, the entertainment system comprises a first kernel module, a first signal module and a first power management module. After receiving the first event, the first kernel module injects the first event into the input subsystem. The first signal module updates the power state attribute of the entertainment system when the first event is included in the input subsystem. The first power management module sends a notification of entering the suspend-to-ram mode to the first target application registered in the entertainment system, and sends a complete message to the first kernel module after receiving the complete message sent by the first target application. The first kernel module receives the enter suspend-to-ram instruction sent by the first power management module, and changes the power state of the entertainment system to the suspend-to-ram state. The instrument system controls the system to enter the suspend-to-ram mode when the power state of the entertainment system is in the suspend-to-ram state.

[0147] In the embodiment, the instrument system comprises a second kernel module, a second signal module and a second power management module. The second signal module sends a notification of entering the suspend-to-ram mode to the second target application registered in the instrument system when the power state of the entertainment system is in the suspend-to-ram state, and sends an enter suspend-to-ram instruction to the second kernel module after receiving the complete message sent by the second target application. The second kernel module receives the enter suspend-to-ram instruction sent by the second signal module, and sends a successful enter suspend-to-ram message to the second power management module. The second power management module receives the successful enter suspend-to-ram message sent by the second kernel module, and sends a successful enter message to the micro-control system.

[0148] The intelligent cockpit system provided by the application comprises a micro-control system and an application processing system. The micro-control system sends a cold start instruction to the application processing system.

[0149] Figure 4 A signaling interaction flowchart of an intelligent cockpit system provided by an embodiment of the application is shown. As shown in Figure 4 The method provided by the embodiment can comprise the following steps:

[0150] S401, the instrument system is started, and registration of suspension to memory notification mechanism of a second target application in the instrument system is performed.

[0151] S402, the entertainment system is started, and registration of suspension to memory notification mechanism of a first target application in the entertainment system is performed.

[0152] S403, when the micro-control system monitors that the whole vehicle signal meets the condition of entering suspension to memory, the power state of the intelligent cockpit system is switched to the power state corresponding to the suspension to memory mode (STR power state).

[0153] S404, the micro-control system sends an entering suspension to memory instruction to the instrument system.

[0154] S405, after the instrument system receives the entering suspension to memory instruction, a first event is sent to the entertainment system.

[0155] S406, a first kernel module of the entertainment system receives the first event and injects an input (Input) subsystem.

[0156] S407, when the first signal module of the entertainment system monitors that the first event is included in the input subsystem, the power state attribute of the entertainment system is updated.

[0157] S408, when the first power management module of the entertainment system monitors that the power state attribute of the entertainment system changes, the first target application registered in the suspension to memory notification mechanism of the entertainment system is sent a notification of entering suspension to memory, so that the first target application performs entering suspension to memory processing.

[0158] S409, the first power module receives a completion message sent by the first target application, closes the external device connected to the entertainment system, and sends an entering suspension to memory instruction to the first kernel module of the entertainment system.

[0159] The first target application includes an internal application (internal client) in the entertainment system and an external application (external client) in communication with the entertainment system.

[0160] S410, after the first kernel module receives the entering suspension to memory instruction sent by the first power module, the power state of the entertainment system is updated to a suspension to memory state.

[0161] It should be noted that updating the power state of the entertainment system to the suspension to memory state can be understood as an identifier indicating that the entering suspension to memory mode of the entertainment system is successful, which is different from the switching of the power state of the intelligent cockpit system to the power state corresponding to the suspension to memory mode in step S403.

[0162] S411, after the second signal module of the instrument system monitors that the power state of the entertainment system is in the suspend-to-ram state, the second target application registered in the suspend-to-ram notification mechanism of the instrument system is sent to enter the suspend-to-ram notification, so that the second target application enters the suspend-to-ram processing.

[0163] The second target application includes an internal application in the instrument system and an external application communicated by the instrument system.

[0164] S412, after the second signal module receives the completion message sent by the second target application, the second kernel module of the entertainment system is sent to enter the suspend-to-ram instruction.

[0165] S413, after the second kernel module receives the enter suspend-to-ram instruction sent by the second signal module, the second power management module (PMIC module) is sent to successfully enter the suspend-to-ram message.

[0166] S414, after the second power management module receives the successfully enter suspend-to-ram message sent by the second kernel module, the micro control system is sent to enter the success message.

[0167] S415, after the micro control system receives the enter success message, the peripherals of the intelligent cockpit system are powered off, and the intelligent cockpit system is controlled to enter the sleep mode.

[0168] At this point, the intelligent cockpit system enters the suspend-to-ram mode.

[0169] S416, when the micro control system monitors that the vehicle signal meets the suspend-to-ram exit condition, the power state of the intelligent cockpit system is switched back to the normal state (non-STR state).

[0170] S417, the micro control system sends the suspend-to-ram exit instruction to the instrument system.

[0171] S418, the second target application in the instrument system exits the suspend-to-ram mode.

[0172] S419, the instrument system sends a third event to the entertainment system.

[0173] S420, the first kernel module of the entertainment system updates the power state of the entertainment system to the non-STR state, and injects the third event into the input subsystem.

[0174] It should be noted that updating the power state of the entertainment system to the non-STR state can be understood as an identifier indicating that the entertainment system exits the suspend-to-ram mode.

[0175] S421, when the first signal module of the entertainment system listens to the input subsystem including the third event, the power state attribute of the entertainment system is updated.

[0176] S422、the first power management module of the entertainment system monitors the change of the power state attribute of the entertainment system, and sends a notification of exiting the suspension to memory to the first target application, so that the first target application performs the exiting suspension to memory processing.

[0177] S423、the first power management module receives the completion message sent by the first target application.

[0178] S424、the instrument system monitors the completion message sent by the first target application in the first power management module, and sends an exit success message to the micro control system.

[0179] At this point, the smart cockpit system exits the suspension to memory mode.
