Example one

Fig. 1 is a flowchart of a vehicle controller remote quiet upgrade method according to an embodiment of the present invention, where the present embodiment is applicable to a situation of remote quiet upgrade of a vehicle controller, and the method may be performed by a vehicle controller remote quiet upgrade apparatus, which may be implemented in hardware and/or software, and may be configured in a vehicle controller remote quiet upgrade device. As shown in fig. 1, the method includes:

s110, obtaining a controller upgrading packet issued by a cloud, and silently writing the controller upgrading packet into a first system of a target controller of a target vehicle to upgrade the first system; the target controller is provided with two systems, namely a first system and a second system, and before the target controller is upgraded, the target controller operates under the second system, and the first system is in a stop operation state.

The method is suitable for the scene of remote silent upgrade of the vehicle controller. The first system and the second system exist in the target controller at the same time, when the target controller operates under any system, the other system is in a stop operation state, and the controller upgrading packet sent by the cloud is subjected to silent flashing in the system in which the target controller stops operating, so that the normal operation of the target controller cannot be interfered in the silent flashing process of the upgrading packet.

In an example, an A/B dual system exists in a vehicle-mounted controller, when an Over-The-Air (OTA) cloud end exists in an upgrade package of an upgrade system, a vehicle-end OTA component receives The upgrade package issued by The OTA cloud end, The upgrade package is subjected to silent flashing in a controller B system under a proper condition, The system B does not operate at The moment, The system A operates normally, when a user appoints to upgrade, an operating system is switched from The system A to The system B, The system B operates normally, The system A does not operate, and therefore The method effectively saves upgrade time and enhances user experience.

The controller upgrading package is used for upgrading the controller system, so that the vehicle performance is optimized, and the defects of the old system version are overcome. The silent flashing can be performed without the operation of a user, and the target controller system can be directly subjected to silent flashing in the target controller system which is not operated after the target controller system meets the condition.

In this embodiment, optionally, before the silent flashing of the controller upgrade package into the first system of the target controller of the target vehicle, the method further includes:

judging the state information of the target vehicle; wherein the status information comprises at least one of: vehicle speed information, battery information, and gear information;

if the state information meets the preset condition, executing silent flashing operation;

and if the state information does not meet the preset condition, performing silent flashing again when the target vehicle is powered on next time.

The state information of the vehicle may be used to represent the state information of the vehicle, and it may be determined what state the vehicle is in according to the state information of the vehicle, and the state information of the vehicle may be information such as vehicle speed information, battery information, or gear information. The vehicle speed information may be information on the speed at which the vehicle is currently located, and is used to determine whether the vehicle is in a running or stopped state. The battery information may be that the battery is low and the battery is normal. The gear information may be gear information such as parking gear, reverse gear, neutral gear, or forward gear. The preset condition may be set according to an actual situation, and is used to determine whether the silent flashing operation is possible, for example, the preset condition may be that the vehicle speed is less than or equal to 20KM/h, the battery voltage is greater than or equal to 24V, and the silent flashing operation is performed when the gear is in a neutral gear or a parking gear.

Optionally, before the controller upgrade package exists in the OTA cloud of the target vehicle, the state information of the target vehicle needs to be determined before the controller upgrade package is silently written into the first system of the target controller of the target vehicle in a CAN or ethernet manner. If the state information of the vehicle meets the preset condition, executing silent flashing operation; and if the state information of the vehicle does not meet the preset condition, performing silent flashing again when the target vehicle is powered on next time.

According to the technical scheme, whether the state information of the target vehicle meets the preset condition or not is judged through the received state information of the target vehicle, and whether the silent flashing operation is carried out or not is further determined, so that the silent flashing of the upgrading packet of the controller can be effectively realized into a system of a target controller of the target vehicle, the silent flashing process is prevented from being interrupted suddenly, and the silent flashing time is prevented from being wasted.

In this embodiment, optionally, after the controller upgrade package is flashed into the first system of the target controller of the target vehicle in a quiet manner, the method includes:

carrying out data consistency check on the controller upgrading packet;

if the verification is successful, the controller upgrade packet is subjected to silent flashing successfully;

and if the verification fails, the controller upgrading packet fails to perform silent flashing, data consistency verification is performed again after the silent flashing is performed again, and if the continuous silent flashing times reach a preset threshold value, the silent flashing is stopped, and the information of the silent flashing failure is fed back to the cloud.

The data consistency means that the upgrade packet data flashed in the system in a silent manner is consistent with the OTA cloud upgrade packet data. The preset threshold may be set according to actual conditions, and the preset threshold may be 2 times, 3 times, or the like.

Optionally, after the controller upgrade package is subjected to silent flashing in the first system of the target controller of the target vehicle, data consistency verification needs to be performed on the controller upgrade package, whether the controller upgrade package subjected to silent flashing is correct is judged, and then whether the controller upgrade package subjected to silent flashing is successful is judged. If the verification is successful, the controller upgrade packet is subjected to silent flashing successfully; and if the verification fails, the controller upgrade package is subjected to silent flashing failure, data consistency verification is carried out again after the silent flashing is carried out again, if the continuous silent flashing times reach a preset threshold value, the silent flashing is stopped, and the information of the silent flashing failure is fed back to the cloud.

According to the technical scheme, whether the controller upgrading packet is subjected to silent flashing successfully or not and the operation after the silent flashing succeeds or fails is judged by checking the data consistency of the controller upgrading packet, so that the controller upgrading packet after the silent flashing is accurate, and the condition that a vehicle cannot be normally used when the system is subsequently converted due to the error of the controller upgrading packet is prevented.

S120, when the controller upgrading packet is subjected to silent flashing successfully, switching the running system of the target controller from a second system to a first system so as to upgrade the target controller; and after the switching is finished, the second system is in a running stop state so as to perform silent flashing when the target controller is updated next time.

Optionally, after the controller upgrade package is successfully subjected to silent flashing, upgrade information needs to be sent to a user associated with the vehicle, the user associated with the vehicle switches the operating system of the target controller from the second system to the first system after confirmation, after the switching is completed, the second system stops operating, the silent flashing operation is performed again when waiting for next controller upgrade, and the controller upgrade package which is not subjected to silent flashing needs to be subjected to silent flashing when the second system is subjected to the next silent flashing, so that consistency of upgrade versions of the two systems is ensured, and omission of upgrade is avoided.

In this embodiment, optionally, before the switching the operating system of the target controller from the second system to the first system, the method further includes:

sending upgrade information to a user associated with the vehicle;

before receiving a confirmation upgrading response of the user, the target controller keeps running under a second system, and sends upgrading information to the user again when the target vehicle is powered on next time;

and after receiving the upgrade confirmation response of the user, switching the operating system of the target controller from the second system to the first system.

According to the technical scheme, the upgrading information is sent to the vehicle-associated user, when the vehicle-associated user confirms upgrading, the operating system of the target controller is switched from the second system to the first system, upgrading operation is carried out after permission of the user is obtained, and user experience is improved. Illustratively, the upgrade information is notified to a user associated with the vehicle, such as a driver or a vehicle owner, through a vehicle-mounted display screen or a mobile phone APP.

In the technical solution of this embodiment, optionally, after receiving a response of confirming the upgrade from the user, switching the operating system of the target controller from the second system to the first system includes:

receiving a upgrade confirmation response of a user as an appointment upgrade;

after the appointed time is reached, judging whether the state information of the target vehicle meets the upgrading condition;

and if so, switching the operating system of the target controller from the second system to the first system.

The upgrade condition may be determined by a vehicle speed, gear information, or battery level information of the vehicle. For example, when the vehicle speed is less than or equal to 20KM/h, the battery voltage is greater than or equal to 24V, and the gear is a neutral gear or a parking gear, the upgrade condition is satisfied.

According to the technical scheme, after the user makes an appointment for upgrading, when the vehicle information state meets the upgrading condition, the operation system of the target controller is switched from the second system to the first system, the situation that the vehicle cannot normally operate due to wrong switching of the operation system of the target controller is prevented, the vehicle is accurately upgraded, and meanwhile the time for upgrading the system by the user is saved.

In this embodiment, optionally, after the controller upgrade package is successfully flashed in a silent mode, switching the operating system of the target controller from the second system to the first system includes:

and if the running system of the target controller fails to switch, the target controller rolls back to the second system, and feeds back a system switching failure result to the cloud.

According to the technical scheme, when the vehicle information state meets the upgrading condition, the operation system of the target controller fails to be switched, the target controller rolls back to the second system, the second system continues to operate instead of operating the second system after the silent flashing operation is carried out again, the situation that the vehicle cannot normally operate due to the fact that the system is subjected to the silent flashing operation again is prevented, and meanwhile the waiting time of a user is greatly reduced.

According to the technical scheme of the embodiment of the invention, the controller upgrading packet sent by the cloud end is obtained, and the controller upgrading packet is subjected to silent flash into the first system of the target controller of the target vehicle so as to upgrade the first system; the target controller is provided with two systems, namely a first system and a second system, and before the target controller is upgraded, the target controller operates under the second system, and the first system is in a stop operation state; when the controller upgrade package is successfully subjected to silent flashing, switching the operating system of the target controller from the second system to the first system so as to upgrade the target controller; after the switching is completed, the second system is in a running stop state, so that silent flashing is performed when the target controller is upgraded next time, the problems that the upgrading time is too long and the controller is unavailable due to failure of silent flashing are solved, the upgrading time of the system is effectively shortened, and the experience effect of a user is improved.

Example two

Fig. 2 is a flowchart of a remote silent upgrade method for a vehicle controller according to an embodiment of the present invention. In this embodiment, a controller upgrade package issued by a cloud is acquired, and the controller upgrade package is statically written into a first system of a target controller of a target vehicle, so as to upgrade the first system; the target controller is provided with two systems, namely a first system and a second system, and before the target controller is upgraded, the target controller operates under the second system, and the first system is in a stop operation state; when the controller upgrading packet is subjected to silent flashing successfully, switching the operating system of the target controller from the second system to the first system so as to upgrade the target controller; and after the switching is finished, the second system is in a running stop state so as to perform silent flashing when the target controller is upgraded next time.

For example, referring to fig. 2, after determining that a new controller upgrade package is available at the OTA cloud, the vehicle-side OTA component receives the upgrade package issued by the OTA cloud, and performs silent transmission when the controller to be subjected to silent flashing identifies the first system and the second system (the second system is currently running, and the first system is in a stationary state), at this time, the OTA component acquires the state information of the current vehicle, and performs silent flashing again when the vehicle is powered on next time until the conditions that the vehicle speed is less than or equal to 20KM/h, the battery voltage is greater than or equal to 24V, and the gear is neutral or parked are met; if the conditions that the vehicle speed is less than or equal to 20KM/h, the battery voltage is more than or equal to 24V and the gear is in a neutral gear or a parking gear are met, the upgrading packet is subjected to silent flashing into a first system of the controller in a CAN or Ethernet mode, the diagnosis silent flashing of a Hybrid Control Unit (HCU) is finished, and then after data consistency verification is successful, upgrading information is notified to a user of a target vehicle through a vehicle-mounted display screen or a mobile phone APP; and if the data consistency verification fails, the controller upgrading packet fails to perform the silent flashing, performs the data consistency verification again after performing the silent flashing again, stops the silent flashing if the continuous silent flashing times reach a preset threshold value, and feeds back the information of the silent flashing failure to the cloud. When a user receives the upgrade information and confirms that the upgrade is performed immediately, the OTA component sends a restart instruction to the HCU, the HCU restarts, the running system is switched from the second system to the first system, after the second system is switched successfully, the OTA component is informed of the success of the upgrade, the upgrade information is informed of the user through the vehicle-mounted display screen or the mobile phone APP, and the upgrade is finished. If the user selects the reserved upgrading, the OTA component judges whether the vehicle meets the upgrading condition after the preset time point is reached, and if yes, the whole vehicle CAN network is awakened to upgrade the controller. And if the upgrading fails, the first system is unavailable, the second system is continuously used, the OTA component is informed of the failure of the flashing, and the result is fed back to the OTA cloud. The upgrade task is not notified to the user, and the user does not perceive the upgrade task.

According to the technical scheme, before the target controller is upgraded, the target controller operates under the second system, and the first system is in a stop operation state. After the controller upgrade package issued by the cloud is obtained, the controller upgrade package is subjected to silent flashing into a first system of a target controller of a target vehicle to upgrade the first system, after the controller upgrade package is subjected to silent flashing successfully, an operation system of the target controller is switched from a second system to the first system to upgrade the target controller, after the switching is completed, the second system is in a stop operation state to perform the silent flashing when the target controller is upgraded next time, the problems that the upgrade time is too long and the controller is unavailable due to failure of the silent flashing are solved, the system upgrade time is effectively shortened, and the user experience effect is improved.
