All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Firstly, the whole-vehicle OTA upgrading system is described, the whole-vehicle OTA upgrading system comprises a vehicle end and a mobile end, the mobile end can be mobile equipment with a remote communication function such as a mobile phone, the vehicle end comprises a central controller and an execution controller, the central controller can be a CEM (Central Electronic Module, central electronic control module), and the central controller is used for executing vehicle upgrading. The execution controller may include a HUT, a multimedia display host, and a request entry/exit control for the whole car OTA mode. TBOX (Telematics Box, on-board wireless terminal module) for restricting remote functions in a vehicle upgrade mode. AC (Air Conditioning control module) is not operated in the vehicle upgrade mode. ESP (Electronic Stability Program, electronic stability control module), VCU (Vehicle Control System, vehicle control module).
The embodiment of the invention provides a whole-vehicle OTA upgrading method, which is applied to a central controller of a vehicle, referring to fig. 1, fig. 1 shows a step flow chart of the whole-vehicle OTA upgrading method, and the method comprises the following steps:
s101: under the condition that a request for entering an upgrade mode of the whole vehicle is obtained, judging whether the upgrade requirement of the central controller is met according to the current vehicle condition.
In this embodiment, after receiving the update message pushed by the vehicle factory, the user may select different upgrade modes according to the environment where the user is located, and generate upgrade request signals in different modes, which may specifically include the following steps:
s101-1: and acquiring a local whole vehicle upgrade mode entry request through a multimedia user interface.
In this embodiment, when the user obtains the update message pushed by the vehicle factory, if the environment where the user is located is just in the vehicle, the corresponding update key may be triggered by the multimedia display host, a request signal of the local mode update request signal may be generated, and the request signal of the local mode update request signal may be sent to the central controller CEM through the CAN bus.
S101-2: and acquiring a remote whole vehicle upgrading mode entering request through the mobile terminal.
In this embodiment, when the user obtains the update message pushed by the vehicle factory, if the environment in which the user is located is not in the vehicle, and if the user is in a room or other environments, the user may trigger a corresponding upgrade key through the APP of the mobile terminal, generate a request signal of a remote mode upgrade request signal, and send the request signal of the remote mode upgrade request signal to the central controller CEM through the CAN bus.
In the embodiments of S101-1 to S101-2, the mobile terminal may be other authenticated electronic devices, such as a tablet, an intelligent bracelet, and an intelligent watch, in addition to the mobile phone, and based on the above embodiments, the application range of the OTA upgrade method is greatly improved, and the user can select a suitable upgrade scheme according to the actual environment where the user is located, and upgrade the mobile terminal in a suitable time, without being restricted to going to a 4S store for upgrade, so that the time cost and financial cost consumed for going to the 4S store for upgrade are greatly reduced.
After the CEM acquires the request for entering the whole vehicle upgrading mode, the CEM needs to judge whether the upgrading requirement of the CEM is met according to the current vehicle condition information, and the CEM comprises the following specific steps:
s101-3: acquiring the current speed, parking state and high-voltage on-state of the vehicle;
s101-4: and under the condition that the current vehicle speed is zero, the parking state is the off state and the high-voltage power-on state is the on state, determining that the upgrading requirement of the central controller is met.
In the embodiments from S101-3 to S101-4, whether the central controller meets the upgrade requirement is determined by acquiring parameters such as the current speed of the vehicle, the parking state of the vehicle, and the high-voltage power-on state, and the upgrade requirement of the central controller can be determined only when the current speed of the vehicle is zero, the parking state is the off state, and the high-voltage power-on state is the on state, and if any one of the above conditions is the requirement, the central controller does not meet the upgrade requirement and sends a signal of "enter upgrade mode error" to the multimedia display host or the mobile terminal. The method is used for representing the state abnormality of the current central controller to the multimedia display host or the mobile terminal, and cannot meet the upgrading requirement.
S102: and under the condition that the upgrading requirement of the central controller is met, sending self-checking signals to a plurality of execution controllers.
In this embodiment, after the central controller meets the upgrade requirement, that is, after the first heavy upgrade verification is met, each execution controller needs to send a self-checking signal for collecting the status signal of the whole vehicle upgrade mode fed back by each execution controller.
S103: and receiving a complete vehicle upgrading mode state signal fed back by each execution controller after receiving the self-checking signal, and judging whether the upgrading requirement of the execution controller is met according to the complete vehicle upgrading mode state signal.
In this embodiment, after receiving the self-checking signal, the different execution controllers generate the whole vehicle upgrade mode status signal according to different judging parameters and judging conditions, where the whole vehicle upgrade mode status signal includes an upgrade mode fault signal and an upgrade mode readiness signal, and only if the judging conditions of the execution controllers are all satisfied, the corresponding upgrade mode readiness signal is generated.
As an example, for an ESP, when it receives a self-test signal, the current vehicle speed and the state of the electronic parking brake system are acquired, and only if the current vehicle speed is zero and the state of the electronic parking brake system is in the hugging state, it is determined that the ESP is ready for upgrade, i.e., the ESP generates an upgrade mode ready signal, otherwise the ESP generates an upgrade mode fault signal. For TBOX, after the self-test signal is currently received, it does not need other decision conditions, and TBOX directly generates an upgrade mode ready signal. And for the VCU, after the self-checking signal is currently received, the power-on state and the current vehicle speed of the VCU are obtained, and only when the power-on state and the current vehicle speed of the VCU are zero, the VCU can be determined to be ready for upgrading, namely the VCU can generate an upgrade mode ready signal, otherwise, the VCU can generate an upgrade mode fault signal. After receiving the upgrade mode fault signal, the central controller determines that the condition of entering the whole vehicle upgrade mode is not met at present, and pauses the upgrade operation until the fault is eliminated, so that the condition that the upgrade process is terminated due to the fault in the upgrade process is avoided.
And the step that the central controller judges whether the upgrade requirement of the execution controller is met according to the whole vehicle upgrade mode state signal fed back by each execution controller comprises the following steps:
and under the condition that the state signal of the whole vehicle upgrading mode fed back by each execution controller is an upgrading mode ready signal, determining that the upgrading requirement of the execution controller is met.
In this embodiment, only when all the vehicle upgrade mode status signals fed by the execution controller are upgrade mode ready signals, it is determined that the execution controller dimension meets the upgrade requirement, and the vehicle upgrade mode can be entered only when the central controller dimension and the execution controller dimension meet the upgrade requirement. By executing the judgment of the upgrading requirements of the two dimensions of the controller and the central controller, the vehicle can be ensured to the greatest extent not to exit the whole vehicle upgrading mode due to the reason of executing the controller in the upgrading process. And meanwhile, the time consumption caused by frequently exiting the upgrade mode is greatly reduced. Therefore, the upgrading process is simple and quick, and the user experience is greatly improved.
S104: and under the condition that the upgrade requirements of the execution controllers are met, transmitting an upgrade mode starting signal of the whole vehicle to each execution controller, and entering an upgrade flow of the central controller.
In this embodiment, after the central controller sends the entire vehicle upgrade mode start signal to each execution controller and the multimedia display host through the CAN bus, the central controller updates and upgrades the software according to the file downloaded in advance. And the central controller needs to maintain the power mode in an on state after entering the whole vehicle upgrade mode.
In the process of upgrading the central controller, the upgrading time of the central controller needs to be monitored, and the specific steps of the central controller can be as follows:
s104-1: and starting an upgrade timer, wherein the upgrade timer is used for recording the actual upgrade time of the central controller and sending a complete vehicle upgrade mode ending signal and an upgrade state message to the execution controller under the condition that the actual upgrade time is greater than a preset upgrade time threshold value.
In this embodiment, the central controller sends a complete vehicle upgrade mode start signal to each execution controller and the multimedia display host through the CAN bus and starts an upgrade timer, where the upgrade timer is used to record the actual upgrade time of the central controller, and if the actual upgrade time of the central controller exceeds a preset upgrade time threshold, the complete vehicle upgrade mode is exited, and the preset upgrade time threshold may be 30 minutes.
The upgrade process of the central controller is monitored through the upgrade timer, and the whole vehicle upgrade mode is forcedly exited under the condition that the actual upgrade time of the central controller exceeds a preset upgrade time threshold value, so that the situation that the whole vehicle upgrade mode cannot be exited due to the upgrade abnormality of the upgrade process of the central controller is avoided.
S104-2: and under the condition that the whole vehicle upgrading mode exit request is acquired, sending a whole vehicle upgrading mode end signal and an upgrading state message to the execution controller.
In this embodiment, after the central controller finishes the upgrading and then ends the restarting, a signal message is sent to the mobile terminal or the multimedia user interface according to the signal format before restarting, and the mobile terminal or the multimedia user interface can determine that the central controller has finished the upgrading after receiving the signal message. Therefore, the central controller sends a request for ending the whole vehicle upgrading mode exit to the central controller, the central controller sends a signal for ending the whole vehicle upgrading mode to the execution controller, the central controller changes the self mark record, and the execution controller executes a corresponding response strategy after receiving the signal for ending the upgrading mode, so that the whole vehicle upgrading mode is exited. After receiving the exit request of the whole vehicle upgrading mode, the central controller also sends an upgrading state message to each execution controller, wherein the upgrading state message is used for representing whether the current state of the whole vehicle upgrading mode is an entering state or an exiting state.
In one possible implementation, the vehicle upgrade mode exit request may be obtained by:
acquiring a local whole vehicle upgrading mode exit request through a multimedia user interface;
and/or acquiring a remote whole vehicle upgrading mode exit request through the mobile terminal.
The embodiment of the invention provides another whole-vehicle OTA upgrading method, which is applied to an execution controller of a vehicle, referring to fig. 2, fig. 2 shows a step flow chart of another whole-vehicle OTA upgrading method in the embodiment of the invention, and the method comprises the following steps:
s201: after receiving the self-checking signal sent by the central controller, generating a complete vehicle upgrading mode state signal according to a preset judging condition, and feeding back the complete vehicle upgrading mode state signal to the central controller.
In this embodiment, after receiving the self-checking signal, the different execution controllers generate the whole vehicle upgrade mode status signal according to different judging parameters and judging conditions, where the whole vehicle upgrade mode status signal includes an upgrade mode fault signal and an upgrade mode readiness signal, and only if the judging conditions of the execution controllers are all satisfied, the corresponding upgrade mode readiness signal is generated.
As an example, for an ESP, when it receives a self-test signal, the current vehicle speed and the state of the electronic parking brake system are acquired, and only if the current vehicle speed is zero and the state of the electronic parking brake system is in the hugging state, it is determined that the ESP is ready for upgrade, i.e., the ESP generates an upgrade mode ready signal, otherwise the ESP generates an upgrade mode fault signal. For TBOX, after the self-test signal is currently received, it does not need other decision conditions, and TBOX directly generates an upgrade mode ready signal. And for the VCU, after the self-checking signal is currently received, the power-on state and the current vehicle speed of the VCU are obtained, and only when the power-on state and the current vehicle speed of the VCU are zero, the VCU can be determined to be ready for upgrading, namely the VCU can generate an upgrade mode ready signal, otherwise, the VCU can generate an upgrade mode fault signal.
S202: after receiving the whole vehicle upgrading mode starting signal sent by the central controller, entering an upgrading flow of the execution controller.
In this embodiment, for different execution controllers, after receiving the whole vehicle upgrade mode start signal, upgrade response is performed according to a predetermined response policy.
As an example, for the multimedia display host, after it receives the whole vehicle upgrade mode start signal, it should control the instrument screen, other non-central control screen, and the like to display the interface that the vehicle is currently being upgraded. And after the ESP receives the starting signal of the whole vehicle upgrading mode, the parking calipers are required to be in a holding state. For the TBOX, after the TBOX receives the whole vehicle upgrading mode starting signal, the remote control function request issued by the App and the Internet of vehicles platform on the mobile terminal is not responded, and the VCU does not judge the vehicle condition state entering the whole vehicle upgrading mode after the TBOX receives the whole vehicle upgrading mode starting signal; in the whole vehicle upgrade mode, the control of the vehicle is not allowed; because the VCU is in the whole-vehicle upgrade mode, the network segments of other CAN except for the pt_can are in a communication silence state, so that the VCU cannot receive signals of other CAN network segments, the VCU needs to maintain a high voltage in an on state under the condition, and cannot actively switch between a high voltage and a low voltage except for receiving an 'otopowertrain' signal to perform a high-low voltage switching action. If the VCU is restarted after the self-upgrading is finished and the upgrading mode ending signal is not received, the default VCU is in a normal upgrading mode, so that the fault reporting phenomenon caused by abnormal restarting of the VCU is avoided.
S203: and after receiving the signal of ending the whole vehicle upgrading mode sent by the central controller, switching the execution controller into a normal working state.
In this embodiment, after receiving the upgrade mode end signal, the non-execution controller executes a corresponding response policy to change the working state to the normal working state, thereby exiting the whole vehicle upgrade mode. As an example, the ESP, TBOX, and VCU each resume their normal functions after receiving the upgrade mode end signal.
In one possible implementation manner, if the upgrade status message sent by the central controller is not received, the whole vehicle upgrade mode state corresponding to the upgrade status message received last time is maintained.
In this embodiment, if the execution controller does not receive the upgrade status message sent by the central controller, it indicates that there is a fault in the current upgrade process, resulting in an abnormal status of the whole vehicle upgrade mode, so that the status of the whole vehicle upgrade mode corresponding to the upgrade status message received last time needs to be maintained.
