Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In practical application, the program updating method provided by the application can be applied to electronic equipment with data processing capability, such as a controller on a vehicle, and an in-vehicle terminal. For convenience of description, the following description will be given only by taking the controller as an example, and the processing logic applied to the in-vehicle terminal is similar, and will not be repeated.
Next, referring to fig. 1, an application scenario of a program updating method provided in an embodiment of the present application is described with reference to fig. 1.
The application scenario in fig. 1 includes an electronic device, a bus, a first device group, and a second device, where the first device group includes a first device 1, a first device 2, and a first device 3. The electronic device is configured to execute the program updating method provided in the embodiment of the present application, the second device is a device that needs to update a program, and the first device group and the second device are connected to the same bus, that is, the first device 1, the first device 2, the first device 3, and the second device are connected to the same bus. Wherein the electronic device can communicate with any device on the bus through the bus. For example, the Electronic device may be a Body Control Module (BCM) in a Vehicle, the second device may be a Battery Management System (BMS) in the Vehicle, the first device 1 may be an Electronic Stability Program (ESP) in the Vehicle, the first device 2 may be an Electronic Parking System (EPB) in the Vehicle, the first device 3 may be a Vehicle Controller Unit (VCU) in the Vehicle, and the bus may be a Controller Area Network (CAN) bus. It should be noted that the application scenario in fig. 1 is only an example, and does not limit the application in any way.
A program updating method provided in an embodiment of the present application is described below. Referring to fig. 2, the program updating method applied to an electronic device includes:
In an embodiment of the present application, the first device group includes at least one first device, and the first device group and the second device are connected to the same bus. The second device may be any device on the vehicle that needs to update the program, that is, when the program needs to be updated on any device on the vehicle, the device may be used as the second device, and then, the other device connected to the same bus as the second device may be used as the first device. For example, the vehicle includes a device 1, a device 2, a device 3, a device 4, and a device 5, the device 1, the device 2, and the device 3 are all connected to the bus 1, the device 4 and the device 5 are not connected to the bus 1, and when the second device is the device 1, the first device group includes the device 2 and the device 3.
And after the preset condition is that the equipment is limited to send data, the vehicle has no potential safety hazard. If the first equipment is detected to meet the preset condition, the situation that the potential safety hazard does not exist in the vehicle after the first equipment is limited to send data is shown.
Alternatively, the first device may be a device that affects the operational safety of the vehicle. It should be noted that, there are devices on the vehicle that may affect the safety of the vehicle, that is, if the devices cannot work properly, the vehicle may have a safety accident (e.g., spontaneous combustion, collision), and therefore, for safety, the first device may be a device that affects the safety of the vehicle, and it should be understood that the device that affects the safety of the vehicle may be defined in advance by the automobile manufacturer according to experience, for example, a Transmission Control Unit (TCU) may be defined as a device that affects the safety of the vehicle.
In this embodiment of the present application, after detecting whether each first device in the first device group meets the preset condition, a detection result of each first device may be obtained, where the detection result is used to indicate whether the corresponding first device meets the preset condition. Then, the third device may be determined in the first device group based on the detection results of the respective first devices. For example, all or part of the first devices in the first device group may be regarded as the third devices according to the detection result.
In this embodiment of the application, after the third device is determined in the first device group, the data transmission behaviors of all the determined third devices may be limited. Wherein the data transmission action refers to an action of the third device to transmit data of any format onto the bus. After limiting the data transmission behavior of the third device, the network load on the bus will be reduced, and then the electronic device can perform program update on the second device.
Optionally, step 203 specifically includes:
and sending a language forbidding instruction to all the determined third devices.
The language-forbidden instruction is used to limit the third device from sending data, that is, after the third device executes the language-forbidden instruction, the third device is limited from sending data.
Illustratively, the talk-back instruction is used to prohibit the third device from sending data, i.e., the third device will not send any data onto the bus when executing the talk-back instruction. Alternatively, the talk-back instruction is used to limit the frequency of data transmission by the third device, i.e. the third device executing the talk-back instruction will limit the frequency of data transmission by the third device, for example, the frequency of data transmission by the third device is limited below a preset frequency threshold. By the two modes, the network load of the bus where the second equipment is located can be reduced, and therefore the success rate of program updating of the second equipment is improved.
In one embodiment, the electronic device may start updating the second device immediately after sending the talk-disable instruction, thereby reducing the waiting time of the user.
In another embodiment, the electronic device may wait for a talk-back result fed back by the third device after sending the talk-back instruction, where the talk-back result is used to indicate that the third device has been successfully restricted from sending data. And the electronic equipment starts to update the program of the second equipment when receiving the language forbidden result. Therefore, the program updating of the second device can be avoided when the third device does not limit the data transmission, and the success rate of the program updating is improved.
Optionally, step 203 specifically includes:
sending a language forbidden instruction and a first language forbidden mark to all the determined third equipment;
the program updating method further includes:
and if the third equipment is not determined in the first equipment group, sending a language-forbidden instruction and a second language-forbidden mark to each first equipment in the first equipment group.
In this embodiment, the first disable flag is used to indicate that the instruction is allowed to be executed, and the second disable flag is used to indicate that the instruction is not allowed to be executed. Specifically, the forbidden words may be represented by a combination of one or more of numbers, letters, and symbols, for example, the first forbidden word is 0, and the second forbidden word is 1, or the first forbidden word is a and the second forbidden word is B, or the first forbidden word is A1 and the second forbidden word is A2, where the form of the forbidden word is not limited herein.
The electronic device may send the language-forbidding instruction and the first language-forbidding flag to all the determined third devices, and the third devices receive the language-forbidding instruction and recognize that the language-forbidding flag is the first language-forbidding flag, determine to execute the language-forbidding instruction. Accordingly, if the third device is not determined in the first device group, the electronic device may send the language-prohibiting instruction and the second language-prohibiting flag to each first device in the first device group, and the first device receives the language-prohibiting instruction and recognizes that the language-prohibiting flag is the second language-prohibiting flag, then it is determined not to execute the language-prohibiting instruction. By sending the language-forbidden instruction and the language-forbidden flag, the first device can know that the current language-forbidden requirement exists, and based on this, after sending the language-forbidden instruction and the second language-forbidden flag to the first device, the program updating method further includes:
monitoring a reminding message sent by first equipment in a first equipment group;
and responding to the reminding message, and returning to execute the step of detecting whether each first device in the first device group meets the preset condition.
The reminding message is used for indicating that the state of the first equipment is changed. The first device starts monitoring the state of the device itself upon receiving the talk-prohibit instruction and the second talk-prohibit flag. It should be noted that, according to different functions of the device, different states monitored by the first device may also be different, for example, the first device group includes a TCU, and the states monitored by the TCU are whether the clutch device is engaged or not and whether a fault occurs or not, and the first device group includes a Motor Control Unit (MCU) and an Engine Control Module (ECM), and then the MCU and the ECM both monitor whether the rotation speed is 0, whether the torque is output or not and whether a fault occurs or not. The first device sends a reminding message to the electronic device once monitoring that the state of the first device changes. In this way, after the state of the first device changes, the first device may change from not meeting the preset condition to meeting the preset condition, and based on this, whenever the state of the first device changes, a reminding message is sent to the electronic device to remind the electronic device to perform step 201 and subsequent steps, so that the electronic device can update the program of the second device in the shortest time.
In one possible implementation, if the third device is not determined in the first device group, the electronic device may not send the talk-disable instruction to any device in the first device group. In this regard, the first device in the first device group should be configured to execute the talk-prohibit instruction when receiving the talk-prohibit instruction, in which case the electronic device does not need to send the talk-prohibit flag, and the first device in the first device group does not need to confirm whether the talk-prohibit flag is the first talk-prohibit flag or the second talk-prohibit flag, as compared to the way the talk-prohibit instruction and the talk-prohibit flag are sent.
Optionally, the first device group further includes at least one fourth device, and before the updating the program of the second device, the method further includes:
and limiting the data transmission behaviors of all the fourth devices.
The fourth device is a device which does not affect the running safety of the vehicle. Therefore, no matter whether the data transmission behavior of the fourth device is limited or not, the vehicle is not caused to have a potential safety hazard. In order to improve the success rate of program upgrade, the electronic device may directly limit the data transmission behaviors of all the fourth devices before updating the program of the second device, without detecting whether the fourth devices satisfy a preset condition.
Optionally, the program updating method further includes:
acquiring a program update file associated with the second device from an upper computer;
the step 203 specifically includes:
and S2031, updating the program of the second device according to the program update file.
The upper computer is connected with the electronic equipment, so that communication between the upper computer and the electronic equipment is realized, the connection can be wireless connection or wired connection, and the connection is not limited here. For example, when the electronic device is a controller, the upper computer may be a vehicle-mounted terminal (central control device) in which a program update file associated with the second device is stored; when the electronic apparatus is a vehicle-mounted terminal (center control apparatus), the upper computer may be a server communicable with the vehicle-mounted terminal, in which a program update file associated with the second apparatus is stored. The program update file associated with the second device is a file for performing program update on the second device.
Optionally, step 2031 specifically includes:
if the second device is the electronic device, updating the program of the second device by executing the program update file;
and if the second equipment is not the electronic equipment, sending the program update file to the second equipment.
In the embodiment of the present application, the second device that needs to update the program may be the electronic device itself that executes the program updating method, or may be another device other than the electronic device. If the second device is the electronic device itself, the electronic device may directly execute the program update file to update the program in the second device (the electronic device), and if the second device is not the electronic device, the electronic device may send the program update file to the second device, and after receiving the program update file, the second device may execute the program update file to update the program in the second device.
Optionally, before the step 201, the program updating method further includes:
receiving a program updating request, wherein the program updating request carries an equipment identifier;
and determining the device corresponding to the device identification as the second device.
In the embodiment of the application, when the program needs to be updated, a program updating request can be sent to the electronic device through the upper computer, and the program updating request carries the device identifier. The electronic device receives the program updating request, and can analyze the program updating request, so as to extract the device identifier carried in the program updating request. The device corresponding to the device identifier is the device that needs to be updated currently, and in the embodiment of the present application, the device corresponding to the device identifier is determined as the second device.
Optionally, the step 202 specifically includes:
judging whether each first device meets a preset condition or not according to each detection result;
if all the first equipment meets the preset conditions, all the first equipment is determined as third equipment;
and if any first equipment does not meet the preset condition, not determining any first equipment as third equipment.
In this embodiment of the application, the electronic device may respectively detect whether the preset condition is satisfied in each of the first devices. If each of the first devices meets the preset condition, each of the first devices in the first device group may be determined as a third device. And if any first equipment in the first equipment group does not meet the preset condition, not determining any first equipment in the first equipment group as third equipment. It should be noted that, based on different functions of the devices, the preset conditions corresponding to the first devices may be different, for example, the first device group includes a TCU, an ECM, and an MCU, where the preset conditions corresponding to the TCU are that the clutch device is not engaged and has no fault, the preset conditions corresponding to the ECM are that the rotation speed is 0, the output torque is 0 and has no fault, and the preset conditions corresponding to the MCU are also that the rotation speed is 0, the output torque is 0 and has no fault.
Optionally, the step 202 specifically includes:
and determining the first equipment meeting the preset condition in the first equipment group as third equipment according to the detection result of each first equipment.
In this embodiment of the application, the electronic device may respectively detect whether the preset condition is satisfied in each of the first devices. And then determining a first device in the first device group, which meets a preset condition, as a third device. For example, assuming that five first devices are included in the first device group, if three of the first devices satisfy the preset condition, the three first devices are determined as the third device, and if all five devices satisfy the preset condition, all of the five first devices are determined as the third device.
Optionally, in order to enable the electronic device to respond to the program update demand in time, the electronic device may select a normal power module on the vehicle, that is, the electronic device is a device that is still in a normal power state after the entire vehicle is powered off and sleeps. Based on this, if there is a program updating requirement, before step 201, the program updating method further includes:
detecting whether each first device is in a power-on state;
and controlling the first equipment which is not in the power-on state to be powered on.
In the embodiment of the application, when the program in the second device needs to be updated, the whole vehicle may be in a power-on working state or a power-off dormant state. Therefore, before step 201, the electronic device may first detect whether each first device in the first device group is in a powered-on state, and if there is a first device in the first device group that is not in the powered-on state, the electronic device may control devices in the device group that affect vehicle operation safety to be powered on. Specifically, the electronic device may control a relay associated with the first device that is not in the power-on state to pull in, so as to implement power-on, where the relay is used to control whether the power supply apparatus supplies power to the first device.
It can be seen from the above that, in this scheme, it is first detected whether each first device in the first device group meets a preset condition, where the first device group and the second device are connected to the same bus, and the preset condition is that there is no potential safety hazard in the vehicle after the first device is limited to transmit data, then a third device is determined according to the detection result in the first device group, and finally, the data transmission behavior of the third device is limited, and the program of the second device is updated. According to the scheme, on the premise of ensuring the running safety of the vehicle, the equipment in the first equipment group is limited to send data so as to reduce the network load of the bus where the second equipment is located, and therefore the program updating success rate of the equipment in the vehicle is effectively improved.
