Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A vehicle mode management method, a vehicle gateway, of an embodiment of the present invention are described below with reference to the drawings.
FIG. 1 is a flow chart of a vehicle mode management method according to one embodiment of the invention.
As shown in fig. 1, the vehicle mode management method includes the steps of:
and S10, communicating with each controller on the vehicle through the vehicle gateway to acquire the state information of each controller.
Specifically, because each Controller on the vehicle has different requirements for the communication mode, optionally, the communication mode may include ethernet, high-speed CAN (Controller Area Network), low-speed CAN, LIN (Local Interconnect Network), FlexRay, and the like, so that in order to solve the interaction of the controllers in different Network segments, a gateway as shown in fig. 2 may be used to forward the message.
As shown in fig. 2, the vehicle gateway communicates with the various controllers on the vehicle via an ethernet, CAN bus and LIN bus. Specifically, a vehicle mode management software module 2 is implanted in the gateway 1, wherein each controller On the vehicle includes an On-Board Diagnostics (OBD) diagnosis interface 3, a vehicle-mounted T-BOX system 4, a battery management system 5, a motor controller 6, a charging and power distribution unit 7, a thermal management controller 8, an intelligent driving area controller 9, an electronic parking system 10, a steering wheel angle sensor 11, a vehicle body stability control system 12, an electric power steering system 13, an airbag controller 14, a vehicle body controller 15, a combination switch control module 16 and a headlamp controller 17. It CAN be understood that the OBD diagnostic interface 3, the vehicle-mounted T-BOX system 4 and the intelligent driving area controller 9 may establish a communication connection with the vehicle gateway 1 through ethernet and CAN buses; the automobile body controller 15, the combined switch control module 16 and the headlamp controller 17 can be in communication connection with the automobile gateway 1 through an LIN bus; the other controllers CAN establish communication connection with the vehicle gateway 1 through the CAN bus. The status of each controller on the vehicle can thus be acquired through the vehicle gateway.
And S20, determining the vehicle to switch modes according to the state information of each controller, sending the mode switching information of the vehicle to other controllers through the vehicle gateway, and performing corresponding function adjustment by the other controllers according to the mode switching information of the vehicle.
Specifically, since the vehicle gateway 1 establishes communication connection with each controller on the vehicle, the state information of each controller can be acquired in real time, and then when it is determined that the vehicle needs to perform mode switching according to the state information of each controller, the mode switching information of the vehicle is sent to other controllers through the vehicle gateway, and then the other controllers perform corresponding function adjustment according to the mode switching information of the vehicle. For example, when the battery management system 5 detects that a voltage fault occurs in a cell inside the battery pack, the cell cannot normally output voltage and current, but can output low power to maintain the power supply of a Critical system of the vehicle, that is, the vehicle is running at a low speed, the battery management system 5 sends a fault level signal to the vehicle gateway 1, and after the vehicle mode management software module 2 embedded in the vehicle gateway 1 detects a fault signal of the battery management system 5, a logic determination is performed to make the vehicle enter a Critical fault mode, in some embodiments, the master node network signal GW _ VMM _ Mainmode is 1 when the vehicle enters the Critical fault mode, optionally, the Critical fault mode further includes a sub-mode limp sub-mode, and in some embodiments, the node network signal VMM _ Critical _ Submode is 0 when the vehicle enters the limp sub-mode. It should be noted that, after the vehicle enters the limp home sub-mode, two mode signals of the critical failure mode and the limp home sub-mode are sent to other controllers through the vehicle gateway 1, and the other controllers perform corresponding adjustment after receiving the signals. For example, the thermal management controller 8 turns off the air conditioner after receiving the signal, the body controller 15 turns off the seat heating function after receiving the signal, and the motor controller 6 limits the power of the vehicle after receiving the signal.
In some examples of the invention, the modes of the vehicle include a normal mode, a critical failure mode, and a software upgrade mode. In the embodiment, when the vehicle is currently in the normal mode, if the critical fault of the vehicle is detected to occur according to the state information of any one controller, the vehicle is determined to be switched from the normal mode to the critical fault mode, and when the critical fault is detected to be cleared according to the state information of the controller, the vehicle is determined to be switched from the critical fault mode back to the normal mode. When the vehicle is in the normal mode at present, if a software upgrading request is detected according to vehicle-mounted T-Box state information in the state information of each controller, the vehicle is determined to be switched from the normal mode to the software upgrading mode, and when the vehicle is detected to be completely upgraded according to the vehicle-mounted T-Box state information, the vehicle is determined to be switched back to the normal mode from the software upgrading mode.
Specifically, the mode of the vehicle may be represented by a master node network signal GW _ VMM _ Mainmode, and then broadcast to each communication bus through different communication modes. More specifically, fig. 3 is a schematic diagram of mode switching of a vehicle, as shown in fig. 3, a normal mode of the vehicle may be set as a default mode, and when the vehicle mode management software module 2 detects that a fault occurs in a current relevant key, the vehicle is controlled to enter a key fault mode from the normal mode, that is, a network signal GW _ VMM _ Mainmode of the master control node is set from 0 to 1; when the vehicle mode management software module 2 detects that the key fault is cleared, the vehicle is controlled to enter a normal mode from the key fault mode, namely, a network signal GW _ VMM _ Mainmode of the master control node is set to be 0 from 1; when the vehicle mode management software module 2 receives a software upgrading request from the vehicle-mounted T-BOX system 4 granted by a user, controlling the vehicle to enter a software upgrading mode from a normal mode, namely setting a network signal GW _ VMM _ Mainmode of a main control node from 0 to 2; when the vehicle mode management software module 2 detects that the software upgrading result is completed, the vehicle is controlled to enter a normal mode from the software upgrading mode, namely, the network signal GW _ VMM _ Mainmode of the main control node is set to 0 from 2.
In some examples of the present invention, the normal mode of the vehicle includes a consumption sub-mode and a charging sub-mode, in which the state of the charging gun is detected according to BMS state information among the state information of the respective controllers, and the sub-mode in which the vehicle is currently located is determined according to the state of the charging gun.
Specifically, in this embodiment, which sub-mode the vehicle is in the Normal mode can be determined by the value of the signal VMM _ Normal _ sub-mode, and when the VMM _ Normal _ sub-mode is 0, the vehicle is in the consumption sub-mode, that is, the vehicle is not effectively charged; when VMM _ Normal _ Submode is 1, then the vehicle is in the charging sub-mode, i.e., the charging gun is effectively plugged into the vehicle. It should be noted that in this embodiment, the VMM _ Normal _ subframe signal is 1 whenever the charging gun establishes an active connection with the vehicle, regardless of whether the vehicle is being charged.
Further, as shown in fig. 4, when the vehicle is currently in the consumption sub-mode, if it is detected that the state of the charging gun is the active insertion state and the power battery pack of the vehicle is in the charging state according to the BMS state information, it is determined that the vehicle is switched from the consumption sub-mode to the charging sub-mode, and when it is detected that the state of the charging gun is the charging gun extraction state according to the BMS state information, it is determined that the vehicle is switched from the charging sub-mode back to the consumption sub-mode.
Alternatively, if a charging fault occurs during charging, the vehicle is controlled to switch from the charging sub-mode to the consumption sub-mode.
In some examples of the invention, as shown in fig. 5, the critical failure modes include a limp home sub-mode, a drive fail sub-mode, and a charge failure sub-mode.
When the BMS state information in the state information of each controller detects that the power output of the vehicle is limited, the vehicle is determined to be switched from the normal mode to the limp sub-mode, when the driving fault of the vehicle is detected according to the state information of each controller, the vehicle is determined to be switched from the limp sub-mode to the driving failure sub-mode, and when the driving fault clearance is detected according to the state information of each controller, the vehicle is determined to be switched from the driving failure sub-mode to the limp sub-mode.
Specifically, the vehicle is in the normal mode. If the state information of the battery management system BMS indicates that the power of the vehicle is limited, the vehicle is switched from the normal mode to a limp home sub-mode in the Critical failure mode, and optionally, which Critical failure mode the vehicle is in may be determined by the VMM _ Critical _ sub signal, in which embodiment, when the VMM _ Critical _ sub signal is 0, the vehicle is determined to be in the limp home sub-mode. Optionally, when the vehicle is in the limp sub-mode, the vehicle speed is limited to within 20km/h, while vehicle comfort related functions such as seat heating function, air conditioning function, etc. will be disabled or limited.
And continuously detecting the state information of each controller of the vehicle when the vehicle is in the limp sub-mode, and if the driving fault of the vehicle is detected from the state information of each controller, switching the vehicle from the limp sub-mode to the driving failure sub-mode, wherein the VMM _ Critical _ Submode is 1. It should be noted that in the driving failure sub-mode, the high-voltage system of the vehicle is disconnected, and the smart driving function and the driving function of the vehicle are not available, while neither the vehicle comfort-related function nor the vehicle safety-related function is available, and the driver is not allowed to drive the vehicle in this mode. When it is detected that the driving fault is cleared from the state information of the respective controllers, it is determined that the vehicle can be switched from the driving failure sub-mode to the limp-home sub-mode.
In this embodiment, during charging of the vehicle, if it is detected that the entire vehicle has failed according to the state information of the respective controllers, it is determined that the vehicle is switched from the normal mode to the charging failure sub-mode, and when it is detected that the charging gun is pulled out according to the BMS state information, it is determined that the vehicle is switched from the charging failure sub-mode to the limp sub-mode.
Specifically, when the vehicle is in the charging sub-mode in the normal mode, if a vehicle failure is detected, the vehicle may be switched from the normal mode to the charging failure sub-mode, and when a charging gun is detected to be pulled out, the vehicle may be switched from the charging failure sub-mode to the limp sub-mode. It will be appreciated that in the charging fault sub-mode, the charging process of the vehicle will be terminated and the high voltage system disconnected, while a warning message may be issued and other functions related to the charging mode will be disabled. Alternatively, the alert message may be an audiovisual message emitted by the vehicle. In addition, when the vehicle is in the charge failure Submode, the signal VMM _ Critical _ Submode is 2.
In conclusion, the vehicle mode management method in the embodiment can avoid unnecessary power consumption of the vehicle, reduce the probability of vehicle failure, and improve the driving safety.
