It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the invention provides a finished automobile control method based on a cloud control system, and as shown in fig. 1, the method specifically comprises the following steps:
and step S10, after the whole vehicle controlled by the whole vehicle domain controller completes initialization, the whole vehicle domain controller packages the state information of the whole vehicle into a state message, and the state message is sent to a vehicle networking platform in the cloud control system through the vehicle-mounted terminal.
In this embodiment, a Vehicle Domain Control User (VDCU) may divide functions of Electronic components of a Vehicle into multiple domains, such as a power transmission Domain, a Vehicle body Electronic Domain, an auxiliary driving Domain, and the like, and then Control most functions originally attributed to Electronic Control Units (ECUs) in each Domain by using a multi-core processor chip with a strong processing capability in a relatively centralized manner, so as to replace a conventional distributed Electronic and electrical architecture. The whole vehicle can be a pure electric bus or other types of pure electric vehicles. The vehicle networking platform is used for large-scale data management and network management. The vehicle-mounted terminal is front-end equipment of a vehicle monitoring management system, and comprises, but is not limited to, a vehicle-mounted video server, a liquid crystal touch screen, an external camera, a call handle and the like.
That is, after the whole vehicle is detected to be awakened in the preset awakening mode, the relevant data and modes of the whole vehicle are initialized. After the fact that initialization of the whole vehicle is detected, the whole vehicle domain controller can package received whole vehicle state information of current working states, fault states and the like of all electric components of the whole vehicle into state messages and send the state messages to the vehicle-mounted terminal, the vehicle-mounted terminal can send the state messages to the vehicle networking platform in real time after receiving the state messages, and the vehicle networking platform analyzes the received state messages to obtain the whole vehicle state information and carries out display and key logic judgment according to the whole vehicle state information. The preset wake-up mode includes a plurality of wake-up modes such as a hard wire based on an electrical architecture and a Controller Area Network (CAN) wake-up message.
Step S20, detecting the running state of the whole vehicle domain controller; the operating states include an awake state and a sleep state.
That is, whether the entire domain controller is in the wake-up state is detected based on the CAN wake-up principle of the entire domain controller. The CAN awakening principle of the whole vehicle domain controller is as follows: when a specific CAN channel has a wake-up message, the whole vehicle domain controller is in a wake-up state, and only when the CAN channel does not have the wake-up message and the CAN wake-up instruction is cancelled, the whole vehicle domain controller stops CAN wake-up, and at the moment, the whole vehicle domain controller is in a dormant state.
Preferably, as shown in fig. 2, step S20 specifically includes the following steps:
step S201, detecting whether a rocker switch in an electrical architecture for a cloud control system is turned on.
And S202, detecting whether a CAN channel of the whole vehicle area controller has no awakening message or not when the rocker switch is turned off.
Step S203, when there is no wake-up message in the CAN channel, the delay count for canceling the CAN wake-up instruction is accumulated, and whether the delay count value is greater than the delay threshold value is detected.
And step S204, when the delay count value is greater than the delay threshold value, the CAN awakening instruction is cancelled, and the running state of the whole vehicle domain controller is a dormant state.
Step S205, when the delay count value is less than or equal to the delay threshold, the process proceeds to step: and detecting whether the whole vehicle is in a remote controllable state.
That is, when it is detected that the rocker switch in the electrical architecture is turned off (i.e., in an off state), it may be determined that the entire domain controller is not awakened through the rocker switch, and it is further determined whether the entire domain controller is awakened through the wakeup packet, in order to avoid the entire domain controller from executing the operation state detection for a long time, a delay counter for canceling the CAN wakeup instruction and a delay threshold for interrupting the operation state detection may be set, and if it is detected that a count value accumulated by the delay counter for canceling the CAN wakeup instruction is greater than the delay threshold, the operation state detection is interrupted, and at this time, the entire domain controller automatically enters a sleep state. And if the count value accumulated by the delay counter for canceling the CAN awakening instruction is detected to be less than or equal to the delay threshold value, the next step S30 is carried out to detect whether the whole vehicle is in a remote controllable state.
In an alternative embodiment, as shown in fig. 2, step S20 specifically includes the following steps:
and step S206, when the rocker switch is turned on, the delay count for canceling the CAN awakening instruction is cleared, and the running state of the whole vehicle domain controller is an awakening state.
That is, when it is detected that the rocker switch in the electrical architecture is turned on (i.e., in a closed state), it is determined that the entire domain controller is awakened through the rocker switch, at this time, the delay counter for canceling the CAN awakening instruction is cleared, and the entire domain controller maintains the awakening state of the previous operation cycle.
In an alternative embodiment, as shown in fig. 2, step S20 specifically includes the following steps:
and step S207, when the CAN channel has the awakening message, resetting the delay count for cancelling the CAN awakening instruction, wherein the running state of the whole vehicle domain controller is the awakening state.
That is, when a wakeup message is detected in the CAN channel, it is determined that the controller in the entire area is awakened through the wakeup message, and at this time, the delay counter for canceling the CAN wakeup instruction is cleared, and the controller in the entire area is in the wakeup state.
And step S30, when the running state of the whole vehicle domain controller is the awakening state, detecting whether the whole vehicle is in a remote controllable state.
Preferably, as shown in fig. 3, step S30 specifically includes the following steps:
step S301, detecting whether the key gear of the whole vehicle and a rocker switch in the electrical framework are both opened.
And S302, when the key gear of the whole vehicle is opened and a rocker switch in an electrical framework for the cloud control system is used, determining that the whole vehicle is in a remote uncontrollable state, invalidating the received cloud control instruction sent by the Internet of vehicles platform, and controlling the whole vehicle to execute corresponding control operation according to the received traditional switch instruction.
Step S303, when the key gear of the whole vehicle and the rocker switch in the electrical framework are not both started, namely when at least one of the key gear of the whole vehicle and the rocker switch in the electrical framework is not started, the whole vehicle is determined to be in a remote controllable state.
Specifically, if the rocker switch and the whole vehicle key gear are detected to be in the closed state, the current driving state of the whole vehicle is determined to be the driver driving state and to be in the remote uncontrollable state, the whole vehicle domain controller sends the information that the whole vehicle is in the remote uncontrollable state to the vehicle networking platform, invalidates the control instruction of the vehicle networking platform, resets the received control instruction to a default value, then recovers the logic control of the traditional switch instruction of the whole vehicle, and returns to the step S10 to execute the whole vehicle control process of the next operation cycle. Understandably, in a remote uncontrollable state, the cloud control instruction is invalidated, so that the cloud control instruction cannot interfere with the actual control of the switch of the whole vehicle component by a driver.
And if the rocker switch and the whole vehicle key gear are detected not to be both in the opening state, the whole vehicle is determined to be in a remote controllable state, and at the moment, in order to ensure the communication safety of the whole vehicle and the vehicle networking platform, whether the whole vehicle enters a cloud control safety mode needs to be further judged. The traditional switch instruction comprises a switch instruction generated by triggering a CAN switch and a hard-wire switch.
And step S40, when the whole vehicle is in a remote controllable state, controlling the whole vehicle and the vehicle-mounted terminal to carry out mutual verification according to the received remote control request sent by the vehicle networking platform, and judging whether the whole vehicle enters a cloud control safety mode or not according to a verification result.
Preferably, as shown in fig. 4, step S40 specifically includes the following steps:
step S401, after the whole vehicle domain controller receives the remote control request sent by the vehicle networking platform, a group of verification initial values generated by the whole vehicle are received, and the verification initial values are input into a preset verification algorithm to obtain verification values.
Step S402, sending the verification initial value to the vehicle-mounted terminal, and receiving a verification secret key returned by the vehicle-mounted terminal.
In step S403, the check value is compared with the check key.
And S404, when the check value is consistent with the check secret key, determining that the whole vehicle enters a cloud control safety mode.
Specifically, when it is detected that the entire vehicle is in the remote controllable state, it is detected whether a remote control request sent by the vehicle networking platform is received, and if the remote control request sent by the vehicle networking platform is not received, the entire vehicle control process of the current operation cycle is ended, and the step S10 is returned to execute the entire vehicle control process of the next operation cycle.
If a remote control request sent by the Internet of vehicles platform is received, the whole vehicle can generate a group of initial Check values, after the whole vehicle domain controller receives the initial Check values, a preset Check algorithm, such as a Cyclic Redundancy Check (Cyclic Redundancy Check) algorithm, is used for calculating to obtain a group of CRC Check values, meanwhile, the initial Check values are sent to the vehicle-mounted terminal, the vehicle-mounted terminal returns a Check key to the whole vehicle domain controller according to the initial Check values, at the moment, the received Check key and the calculated Check values can be compared to judge whether the Check key and the calculated Check values are consistent, if the Check key and the Check values are consistent, the Check key is output as a Check result, and the whole vehicle is determined to enter a cloud control safety mode. And if the check key is inconsistent with the check value, outputting the check failure as the check verification, and determining that the whole vehicle enters the cloud control non-safety mode, at this time, feeding back information that the check result is the check failure to the vehicle-mounted terminal, ending the whole vehicle control process of the current operation period, and returning to the step S10 to execute the whole vehicle control process of the next operation period.
And step S50, when the whole vehicle enters the cloud control safety mode, controlling the whole vehicle to execute corresponding control operation according to the received traditional switch command and the received cloud control command.
Preferably, when the whole vehicle enters the cloud control safety mode, the information that the check result is that the check is passed is sent to the vehicle-mounted terminal, the terminal control instruction sent by the vehicle-mounted terminal according to the preset protocol is received, the response state sent after the whole vehicle executes the terminal control instruction is sent to the vehicle-mounted terminal, and then the whole vehicle is controlled to execute the corresponding control operation according to the received traditional switch instruction and the cloud control instruction.
The terminal control instruction comprises terminal control parameters, when the vehicle domain controller receives the terminal control instruction comprising the terminal control parameters, the vehicle domain controller stores the vehicle-mounted terminal control parameters in a Read Only Memory (ROM) area, and then feeds back a positive response state of the whole vehicle to the vehicle-mounted terminal, and combines the received cloud control instruction sent by the vehicle networking platform and a traditional switch instruction of the whole vehicle to control the whole vehicle to carry out logic output, so that the whole vehicle control process of the current operation cycle is completed, and at the moment, the step S10 can be returned to carry out the whole vehicle control process of the next operation cycle. Understandably, in the cloud control safety mode, the cloud control instruction control and the whole vehicle traditional switch instruction control are in the same level, and the whole vehicle domain controller controls the whole vehicle to execute corresponding control operation according to the finally changed control instruction.
In the above embodiment of the present invention, the entire domain controller is used as the execution subject of each step in the entire vehicle control method based on the cloud control system, but in other embodiments of the present invention, the vehicle-mounted terminal or the vehicle networking platform may also be used as the execution subject of each step in the entire vehicle control method based on the cloud control system.
Therefore, according to the vehicle control method based on the cloud control system provided by the embodiment of the invention, after the initialization of the whole vehicle is completed, the state information of the whole vehicle is uploaded to the vehicle networking platform, then the whole vehicle is controlled to be in the awakening state in the whole vehicle domain, the whole vehicle is in the remote controllable state, the remote control request safety check is carried out, and finally, after the safety check is passed, the cloud control instruction and the traditional switch instruction of the whole vehicle are combined to control the whole vehicle to execute different types of remote control functions, so that the upper-layer control of the whole vehicle is realized.
