Various embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings. The embodiments described by referring to the drawings are exemplary and intended to be illustrative of the invention and are not to be construed as limiting the invention.

In this embodiment, the reset start-up system puts each system function module into a ready state.

In this embodiment, the actuator driving system is driven by receiving a command from a system controller.
In this embodiment, the control strategy system executes different actuator driving commands according to different control commands.
In this embodiment, the power-off processing system executes a power-off operation after receiving a power-off command issued by the control policy system.
The automotive AUTOSAR standard real-time controller resetting starting time optimizing system of the embodiment, the system comprises:
the initialization module is used for reading the MCU reset reason before the RAM ECC is initialized, executing the RAM ECC initialization and the Cache initialization when the MCU reset reason is power-on reset, and executing the data.bss type data initialization and the clock peripheral initialization when the MCU reset is software reset;
the starting module is used for associating the starting mode of the AUTOSAR operating system with the running state of the controller before reset starting after the clock peripheral initialization is executed, starting the AUTOSAR operating system according to a default mode under the condition of power-on reset, setting a predefined application software reset source under the condition of non-power-on reset and before reset restarting, and starting the AUTOSAR operating system under the corresponding starting mode according to the set reset source.

The embodiment is based on the method for optimizing the reset starting time of the automotive AUTOSAR standard real-time controller, and provides an actual embodiment by combining specific objects:
corresponding to the existing reset starting process, the invention adds two steps in the process:
the first step is as follows: before the RAM ECC is initialized, MCU reset reason judgment is added, and when the MCU reset reason is power-on reset, all processes before the AUTOSAR operating system in the figure 1 is started are executed. When the MCU is reset by software (or when the watchdog is reset), working steps such as RAM ECC initialization and the like which do not need to be initialized again (some MCU chips support an instruction Cache and do not need to be initialized again in the non-power-on reset restarting process) are skipped, and data. When applied in an actual project, the specific application can be combined to decide to skip the operation steps.
The second step is that: before the AUTOSAR operating system is started, the starting mode of the operating system is associated with the running state of the controller before the reset starting, and the operating system is started according to the default mode only under the condition of power-on reset. Under the condition of non-power-on reset, before reset and restart, a predefined application software reset source is set, and the operating system is started in a corresponding starting mode according to the set reset source.
The embodiment is based on the method for optimizing the reset starting time of the automotive AUTOSAR standard real-time controller, and provides an actual embodiment by combining specific objects:
as shown in fig. 2, the start-up procedure is as follows:
after the automotive AUTOSAR standard controller is reset, a stack pointer is initialized, the MCU reset reason is read, if the reset reason is power-on reset, RAM ECC initialization and Cache initialization are executed, and if the reset reason is not power-on reset, data. (in practical application, the reason for the non-power-on reset of the MCU can be further subdivided and differentiated treatment can be carried out).
After the initialization of the clock peripheral is executed, the value of a variable StartMode is judged (if the controller is powered on and reset, the value of the StartMode is equal to the filling value of the RAM initialization ECC, if the controller is not powered on and reset, the value of the StartMode is equal to the value of an application software reset source set before the reset and restart of the controller), if the value of the StartMode is equal to the filling value of the RAM initialization ECC, the operating system is started in a default Mode, if the value of the StartMode is not equal to the filling value of the RAM initialization ECC, the operating system is started in a Mode1, and in different starting modes of the TOSAR, the difference of starting tasks can be made according to application scenes before the reset, so that the quick starting is realized. In practical application, the StartMode value can be further subdivided to realize that the AUTOSAR can be started in multiple modes.
As shown in fig. 3, the start-up system is reset: after the reset starting is controlled, firstly executing system reset starting software, and putting each software functional module into a ready state;
the sensor input acquisition system: collecting the values (such as temperature, vehicle speed and the like) of a sensor of a controller according to a certain strategy, and providing input for control strategy software;
an actuator drive system: receiving a system controller command and driving a system actuator;
the control strategy system comprises: the control logic of the system generally executes different actuator driving commands according to different inputs;
a power-down processing system: after receiving the power-off command, each software function module is processed before power-off, and after the processing is finished, the power is turned off.
The vehicle further includes:
a communication interface 403 for communication between the memory 401 and the processor 402.
A memory 401 for storing computer programs operable on the processor 402.
If the memory 401, the processor 402 and the communication interface 403 are implemented independently, the communication interface 403, the memory 401 and the processor 402 may be connected to each other through a bus and perform communication with each other. The bus may be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, an Extended ISA (EISA) bus, or the like. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, only one thick line is shown in FIG. 4, but this does not indicate only one bus or one type of bus.
Optionally, in a specific implementation, if the memory 401, the processor 402, and the communication interface 403 are integrated on a chip, the memory 401, the processor 402, and the communication interface 403 may complete mutual communication through an internal interface.
The processor 402 may be a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), or one or more Integrated circuits configured to implement embodiments of the present Application.
