Detailed Description

For ease of understanding, the present application will be described with reference to specific embodiments and associated drawings.

Fig. 1 is a schematic structural diagram of a fuel cell vehicle according to an embodiment of the present application. As shown in fig. 1, the fuel cell vehicle according to the embodiment of the present invention mainly includes a telematics BOX (T-BOX) (8), a Body Controller (BCM) (2), a Vehicle Controller (VCU) (1), a fuel system controller (FCU) (4), a Motor Controller (MCU) (3), a Battery Management System (BMS) (5), a Power Distribution Unit (PDU) (6), a gateway (gateway, GW) (7) that forwards a body Controller Area Network (CAN) (11) and a chassis CAN (10) to each other, and a combination Instrument (IC) (9) that displays a power icon.

The T-BOX may communicate with the cloud server, for example, the T-BOX may receive a power-on instruction sent by the cloud server, send failure information in the high-voltage power-on process of the fuel cell vehicle to the cloud server, and the failure information in the high-voltage power-on process of the fuel cell vehicle may include VCU initialization failure information, remote high-voltage power-on prohibition information, terminal device authentication failure information, PDU pre-charging contactor non-closing information, and the like.

It should be noted that the architecture diagram shown in fig. 1 is only an example of the fuel cell vehicle provided in the present application, and the fuel cell vehicle provided in the present application may include fewer or more components, for example, a fuel sensor or other type of controller, and the present application is not limited thereto.

The analysis shows that a threshold value is preset in the fuel cell automobile, when the bus voltage of the MCU in the fuel cell automobile is greater than or equal to the threshold value, the vehicle is judged to be precharged and electrified at high voltage; and when the bus voltage of the MCU in the fuel cell automobile is smaller than the threshold value, judging that the vehicle is not precharged and not electrifying at high voltage.

The preset threshold value in the fuel cell vehicle is the same threshold value uniformly set for fuel cell vehicles of different types, models and/or different purposes, so the threshold value is not suitable in some fuel cell vehicles, and unsafe operation of judging that the fuel cell vehicle has been precharged and powered up at high voltage based on the threshold value can occur.

Based on the technical problem, the application provides a new technical scheme capable of safely electrifying at high voltage. In the technical scheme provided by the application, the threshold value set in the fuel cell automobile is not the same threshold value set uniformly with various fuel cell batteries, but is set in a targeted manner according to the target voltage of the battery pack of the fuel cell automobile.

As one example, the threshold may be set to a first percentage of the bus voltage of a battery pack of a fuel cell vehicle. That is, when the bus voltage of the MCU of the fuel cell vehicle is greater than or equal to the first percentage of the bus voltage of the battery pack of the fuel cell vehicle, the fuel cell vehicle determines that the pre-charging is completed and then performs the high-voltage power-up.

As one example, the first percentage may be 95%. That is, when the bus voltage of the MCU of the fuel cell vehicle is greater than or equal to 95% of the bus voltage of the battery pack of the fuel cell vehicle, the fuel cell vehicle determines that the pre-charging is completed and then performs the high-voltage power-up.

In addition, in order to further improve the safety of the high-voltage electrification of the fuel cell automobile, the following technical scheme is provided: before the high-voltage power-on of the fuel cell automobile, the fuel concentration around a battery pack of the fuel cell automobile is detected, and the high-voltage power-on is performed only when the fuel concentration is 0. This can avoid safety problems due to fuel leakage.

For example, when the fuel of a fuel cell vehicle is hydrogen, a hydrogen detection sensor may be installed around the cell pack, and the high-voltage power-up may be performed only when the hydrogen concentration detected by the hydrogen detection sensor is 0.

Further, in order to improve the control flexibility of the fuel cell automobile, the application also provides a method for remotely controlling the power-on of the fuel cell automobile. In the technical scheme provided by the application, the terminal equipment sends the power-on instruction to the fuel cell automobile through the cloud end, and the fuel cell automobile executes the power-on operation after receiving the power-on instruction.

For example, a remote power-on controller may be added to the fuel cell vehicle, where the remote power-on controller is configured to receive a power-on instruction sent by the terminal device through the cloud device and send information for waking up a vehicle controller of the fuel cell vehicle, so that the vehicle controller controls other parts in the fuel cell vehicle to perform a power-on process.

In the technical scheme provided by the application, optionally, the remote power-on controller can send information for indicating the initialization failure of the vehicle control unit to the terminal device through the cloud device under the condition that the initialization of the vehicle control unit fails so as to inform a user of the power-on failure of the fuel cell vehicle and the reason of the power-on failure.

Optionally, during the process of powering on the fuel cell vehicle based on the remote power-on command, the identity of the terminal device or the user may be authenticated, and the subsequent operation may be continued only when the authentication is successful, so as to improve the safety of the fuel cell vehicle.

Optionally, in the case of authentication failure, the remote power-on controller may send, to the terminal device, information indicating that authentication of the terminal device has failed through the cloud device, so as to inform a user of a reason for the power-on failure.

Optionally, in the process of powering on the fuel cell vehicle based on the remote power-on instruction, in the case that the PDU pre-charging contactor is not closed, the remote power-on controller may send, to the terminal device, information indicating that the PDU pre-charging contactor is not closed through the cloud device, so as to inform a user of a reason for a power-on failure.

The method will be described below in conjunction with a fuel cell vehicle shown in fig. 1.

S201, the terminal device sends a power-on instruction to the cloud server.

For example, after the user presses a vehicle power-on button in application software in the terminal device, the terminal device sends a power-on instruction to the cloud server.

The power-on instruction comprises a first identifier and identity information of terminal equipment sending the power-on instruction, and the first identifier is used for indicating a power-on mode.

S202, the T-BOX receives a power-on instruction sent by the cloud server.

The cloud server wakes up the T-BOX by sending a power-on instruction to the T-BOX, and the T-BOX identifies that the current working mode is a power-on mode through a first identifier in the power-on instruction and wakes up the VCU.

S203, the T-BOX awakens the VCU through the CAN network.

For example, the T-BOX may send a CAN packet carrying the first identifier to the VCU through the CAN network, thereby waking up the VCU.

And after receiving the CAN message carrying the first identifier, the VCU identifies that the current working mode is the power-on mode according to the first identifier.

And S204, initializing the VCU.

After the VCU is woken up, it enters the initialization process.

It should be noted that the initialization process of the VCU is common knowledge in the art, and will not be described herein.

S205, the VCU judges whether the initialization is completed.

If yes, go to S206;

if not, then S207-S209 are executed.

S206, the VCU wakes up the BCM through the CAN network, and the BCM executes a low-voltage electrifying process.

Illustratively, the VCU may send a CAN packet carrying the first identifier to the BCM through the CAN network, so as to wake up the BCM.

And the BCM identifies the current working mode as a power-on mode according to the first identifier in the CAN message, and executes a low-voltage power-on process.

It should be noted that, the procedure of performing low-voltage power-up by the BCM in the present application is the same as the process of performing low-voltage power-up by the fuel cell vehicle in the prior art, and details are not repeated here.

Illustratively, the VCU may send a CAN message carrying the identifier of the low voltage relay to the PDU, BMS, MCU and FCU through the CAN network, so as to transmit a command of closing the low voltage relay to the PDU, BMS, MCU and FCU.

S211, the VCU judges whether the execution of the high-voltage electrifying process is forbidden.

For example, the determination rule for the VCU to determine whether to prohibit the execution of the high-voltage power-on procedure may include:

(1) the VCU judges whether the voltage of the 12V battery is greater than or equal to 12V, if so, the fuel cell automobile does not need to be intelligently charged, the VCU CAN execute a high-voltage electrifying process and send the information that the fuel cell automobile does not need to be intelligently charged to the BCM and the T-BOX through the CAN network; if not, the VCU prohibits the execution of the high-voltage power-on process.

It should be noted that, reference may be made to S207 in the process of sending, by the VCU through the CAN network, information that the fuel cell vehicle does not need to be intelligently charged to the BCM and the T-BOX, which is not described herein again.

(2) The VCU judges whether the feedback information of the closure of the PDU, the BMS, the MCU and the FCU low-voltage relay is received, if the feedback information of the closure of the low-voltage relay sent by the PDU, the BMS, the MCU and the FCU is received by the VCU, the VCU can execute a high-voltage power-on process, and if the feedback information of the closure of the low-voltage relay sent by the PDU, the BMS, the MCU and the FCU is not completely received by the VCU, the VCU prohibits the execution of the high-voltage power-on.

(3) The VCU detects whether the fuel concentration in the fuel cell automobile is greater than 0 by using a sensor, and if the fuel concentration in the automobile is equal to 0, the VCU can execute a high-voltage electrifying process; if the in-vehicle fuel concentration is greater than 0, the VCU prohibits the execution of the high-voltage power-on procedure.

Generally, the sensor is installed in a certain range around a battery pack of a fuel cell vehicle in order to detect whether fuel leakage occurs in the battery pack. If leakage occurs, high-voltage power-on is not carried out, and if leakage does not occur, high-voltage power-on is carried out, so that the safety of the vehicle can be improved.

In the present embodiment, hydrogen is one example of the fuel for a fuel cell vehicle. The distance between the sensor and the battery pack may be set empirically.

Judging whether the VCU forbids to execute the high-voltage power-on process according to the judgment rule, and executing S212 if the VCU is allowed to execute the high-voltage power-on process; if the VCU is prohibited from executing the high-voltage power-up process, S213 to S215 are executed.

After receiving authentication request information sent by the VCU, the T-BOX needs to send authentication feedback information to the VCU within preset time, wherein the authentication feedback information comprises identity information of terminal equipment bound with the T-BOX and identity information of terminal equipment sending a power-on command to the cloud server.

If the VCU does not receive authentication feedback information sent by the T-BOX within the preset time, the authentication is not passed; if the VCU receives the authentication feedback information sent by the T-BOX within the preset time, the VCU further determines whether the identity information of the terminal device bound to the T-BOX in the authentication feedback information is consistent with the identity information of the terminal device sending the power-on instruction to the cloud server, if so, the authentication is passed, and S217 is executed; and if the identity information of the terminal equipment bound by the T-BOX is inconsistent with the identity information of the terminal equipment sending the power-on instruction to the cloud server, the authentication is not passed, and S218 to S220 are executed.

Preferably, the preset time may be 200 milliseconds (ms).

And S217, the VCU sends a contactor closing instruction to the BMS through the CAN network, sends a power-on instruction to the FCU, and sends a main contactor closing instruction to the PDU.

Illustratively, the VCU may send a CAN message carrying a contactor closing identifier to the BMS via the CAN network, thereby transmitting a contactor closing instruction to the BMS.
