[0024] Under the above operating environment, an embodiment of the present invention provides a method for quickly starting a vehicle as shown in FIG2 , which is run on the main controller of the vehicle. FIG2 is a flow chart of a method for quickly starting a vehicle according to an embodiment of the present invention. As shown in FIG2 , the method includes the following implementation steps:

[0025] Step S201: When the vehicle starts the fast start mode, a first control instruction is sent to the power manager to control the power manager to perform a power-off operation on the cockpit domain controller;

[0026] Step S202: In response to the wake-up signal of the vehicle, a second control instruction is sent to the cockpit domain controller to control the cockpit domain controller to read functional data corresponding to multiple cockpit functions, a third control instruction is sent to the power manager to control the power manager to perform a power-on operation on the cockpit domain controller, and the vehicle is controlled to perform a quick start of the entire vehicle, wherein the cockpit domain controller after powering on controls multiple cockpit functions to follow the vehicle to start quickly based on the functional data.

[0027] In an embodiment of the present invention, when a vehicle enters fast startup mode, a first control instruction is sent to a power manager to control the power manager to power off the cockpit domain controller; in response to a vehicle wake-up signal, a second control instruction is sent to the cockpit domain controller to control the cockpit domain controller to read functional data corresponding to multiple cockpit functions; a third control instruction is sent to the power manager to control the power manager to power on the cockpit domain controller; and the vehicle is controlled to perform a full vehicle fast startup, wherein the powered-on cockpit domain controller controls multiple cockpit functions to follow the vehicle fast startup based on the functional data. Thus, the present invention achieves the purpose of achieving the fast startup of multiple cockpit functions in the cockpit domain by controlling the vehicle fast startup logic through the main controller, thereby achieving the technical effect of improving the flexibility and richness of cockpit domain functions following the vehicle fast startup, and further solving the technical problem that the cockpit domain controller fast startup solution provided in the related art has a single content and simple functions, which makes it difficult to meet the regionalization and centralized development requirements of the vehicle electronic and electrical architecture.

[0028] In an exemplary application scenario, according to the above-mentioned method steps provided by the present invention, a vehicle control architecture as shown in Figure 3 is provided, and the cockpit domain controller (System-on-chip, abbreviated as SoC), the main controller (Main controller Unit, abbreviated as MCU), the audio module and the video module are integrated to implement a cockpit domain quick startup solution. Specifically, the MCU controls the relevant mode switching logic of the whole machine, thereby realizing multi-module and multi-dimensional customized quick startup of the cockpit domain. In this example, the multiple modules include: an audio input module (such as a microphone), an audio output module (such as a speaker), a video input module (such as a camera), and a video output module (such as a central control screen, an instrument panel).

[0029] Furthermore, as shown in Figure 3, during the rapid startup of multiple modules in the cockpit domain, dynamic random access memory (DRAM) is used to cache and quickly read data involved in the rapid startup process. This DRAM can be a double data rate (DDR) chip. During the rapid startup of multiple modules in the cockpit domain, the power manager manages the power cycle of the MCU, SoC, and DDR chip.

[0030] In this application scenario, the quick start function implemented by the cockpit domain controller is crucial, as it can meet the user's need for rapid cockpit system startup after a brief vehicle shutdown and power outage. Typically, a cockpit system without quick start functionality typically boots up in over 25 seconds, while a cockpit system with quick start functionality typically boots up in around 5 seconds. The method provided in this embodiment of the present invention further enhances existing quick start functionality, providing a comprehensive, novel, and robust quick start logic that can meet the needs of future products.

[0031] In the above application scenarios, the cockpit domain controller operates in three modes: normal startup mode, quick startup mode, and sleep mode. In normal startup mode, the left and right functions of the vehicle's cockpit are used. In quick startup mode, some functions remain in a standby state after a short vehicle shutdown, allowing for a quick response to restarting the vehicle. In sleep mode, a minimum number of modules remain operational after a prolonged vehicle shutdown, reducing the system's power consumption and supporting restarting after a prolonged shutdown.

[0032] Optionally, the plurality of cockpit functions include an audio input function, a video input function and a video output function.

[0033] In fast-start mode, the cockpit domain controller keeps the MCU in sleep mode and controls the power management system. In fast-start mode, the cockpit controller quickly activates cockpit functions including audio output, video output, and video input. Audio output functions include music playback and in-car audio and phone calls; video output functions include instrument displays (such as mileage, speed, and fault alarms) and central control screen displays; and video input functions include reversing cameras and surround-view monitoring.

[0034] Optionally, the above vehicle quick start method may further include the following method steps:

[0035] Step S231: Send a first request message to the cockpit domain controller to request switching to a quick start mode, wherein in the quick start mode, the cockpit domain controller quickly starts multiple cockpit functions in response to vehicle ignition after the vehicle is turned off;

[0036] Step S232: Receive a first response message returned by the cockpit domain controller, and control the vehicle to switch to the quick start mode, wherein the first response message is generated by triggering a cache event of the functional data by the cockpit domain controller.

[0037] In an exemplary application scenario, according to the method steps provided above, the control logic for a vehicle rapid start is provided as shown in FIG4 . In rapid start mode (STR mode), the MCU sends a STR mode request command to the SoC via a function pin. Upon receiving the request command, the SoC processes the data before entering STR mode via its internal CPU (in this example, including the first and second CPUs), and saves the data after processing. Furthermore, the SoC can also support entering STR mode by returning an acknowledgment (ACK) signal to the MCU. Upon receiving the feedback ACK signal, the MCU notifies the power manager to begin powering down the controller and notifies the SoC to enter STR mode. In this example, the power manager can be a power management integrated circuit (PMIC).

[0038] Optionally, in step S201, sending the first control instruction to the power manager to control the power manager to power off the cockpit domain controller may further include the following execution steps:

[0039] Step S211, obtaining a power supply strategy corresponding to the fast startup mode;

[0040] Step S212: generating a first control instruction according to the power supply strategy;

[0041] Step S213: Send a first control instruction to the power manager to control the power manager to perform a power-off operation on the cockpit domain controller according to the power supply strategy.

[0042] Optionally, the power supply strategy includes: maintaining power to the target component and powering off other components in the vehicle except the target component, wherein the target component includes: a data cache component in the cockpit domain controller, a dynamic random access memory of the vehicle, a power management component, a wake-up response component and a timing component in the main controller.

[0043] In the above application scenario, according to the power supply strategy corresponding to the STR mode, when performing the power-off operation: retain the power supply of some internal functional modules of the SoC, so that the SoC can quickly read the data in the cache area in a short time to support fast startup; retain the power supply of the DDR chip, support the DDR chip to remain in the self-refresh state, and support the fast startup of the SoC; retain the power supply of some low-power modules of the MCU, support the power management of the controller and the identification of internal and external wake-up sources, which can meet the requirements of restarting the entire machine.

[0044] Optionally, the above vehicle quick start method may further include the following method steps:

[0045] Step S24 , in response to the vehicle maintaining the quick start mode for longer than a preset time threshold, controlling the vehicle to exit the quick start mode and powering off the entire vehicle.

[0046] In the above application scenario, according to the power supply strategy corresponding to STR mode, when performing a power-off operation: the MCU's internal timing module is powered on to support the MCU internal timing module to complete the set fast boot mode retention time (for example, 12 hours). In addition, if the STR mode retention time exceeds the system-set time, the MCU is supported to control the entire device to completely power off to avoid excessive power consumption.

[0047] Optionally, the wake-up signal includes: an internal signal and an external signal, wherein the internal signal is triggered and generated by the power manager, and the external signal is triggered and generated by an external control device associated with the vehicle.

[0048] Optionally, the second control instruction includes a prompt command, and the prompt command is used to instruct the cockpit domain controller to read the functional data from the cache.

[0049] In an exemplary application scenario, according to the above-mentioned method steps provided by the present invention, an interactive process for vehicle quick start is provided as shown in Figure 5. When the system is turned on and in normal working mode, it is controlled to enter the STR mode. First, a preprocessing process for quick start is performed. The preprocessing process includes data caching, power-off processing, etc.; after completing the preprocessing, the vehicle enters the STR mode.

[0050] Furthermore, in STR mode, when a fast boot wake-up signal is received, the MCU sends a prompt (Command, abbreviated as CMD) command to the SoC, and then the MCU controls the PMIC to start powering on, and further, starts system boot (system boot). After the system boot is completed, it enters the normal working mode, or continues to maintain the STR mode.

[0051] Among the wake-up sources of the wake-up signal, external wake-up sources include: remote control key signals, Bluetooth signals, wireless radio frequency identification (RFID) signals, touch sensor signals, and light sensor signals.

[0052] This invention provides a fast-start control logic and method. By globally controlling the SoC and PMIC through an MCU and collaborating with peripheral modules to implement fast-start entry and exit, the method supports fast startup of various cockpit domain controller system functions, such as various instrument displays or screens, heads-up displays (HUDs), fast audio playback, and surround view and reverse image capture. This method provides users with a straightforward fast-start experience, eliminating long wait times.
