The automatic air conditioner control module starts an internal and external circulation motor, a blowing mode motor, a temperature control motor and a blower motor.
The vehicle owner sends an operation instruction to the cloud platform server at the mobile terminal, and the cloud platform server forwards the operation instruction to the communication module. And after receiving the instruction, the communication module performs authentication and authentication with the keyless starting module. And after the authentication and certification are passed, the keyless starting module and the hybrid controller perform authentication and certification, and the hybrid controller controls high voltage after the authentication and certification are passed. After the remote high-voltage electrification is finished, the hybrid controller receives a 'remote hot car starting' instruction sent by the communication module, the hot car condition is judged, and when the condition is met, the hybrid controller enters a hot car mode; otherwise, the hybrid controller does not enter the remote hot car and feeds back the reason for the remote start failure of the keyless start module, the keyless start module feeds back the remote start failure state to the communication module, and the communication module feeds back the hot car failure state to the APP of the mobile terminal through the server.
And when the hybrid controller is powered on and awakened, the authentication and the authentication are carried out with the keyless starting module through the CAN bus. After the authentication is passed, if the remote high-voltage condition of the hybrid controller is met, the hybrid controller executes a high-voltage power-on process, the whole vehicle enters a READY state, and a READY flag bit of the vehicle is $1= Active and a whole vehicle running mode is $3= RUN, and the READY flag bit and the running mode are sent to a bus. After the hybrid controller is successfully subjected to remote high voltage application, if the hybrid controller is in a remote Control mode (receiving a Vehicle Control Status =1 (remote mode) sent by the keyless start module), and when the remote high voltage application condition is not met, the hybrid controller controls the high voltage application, feeds a high voltage application state signal back to the keyless start module, and feeds back the high voltage application state signal to the mobile terminal, so as to prompt that a battery of an owner Vehicle has a fault and cannot execute a Vehicle heating action.
The hybrid controller collects vehicle information in the vehicle state modules, if the states of the vehicle modules are in normal states, and most importantly, battery electric quantity information in the battery management system, a hot vehicle condition is met, a vehicle battery end provides power for a whole vehicle, various instruments and equipment are started to start the hot vehicle, when the battery electric quantity is low and the hot vehicle action cannot be executed, and an engine system meets the hot vehicle condition, the engine is started to supply power for the whole vehicle system, whether the battery end needs heating and charging is judged, if yes, the battery pack is heated by using the PTC thermistor, and if not, the hybrid controller stops working until the hot vehicle is finished.
When the remote hot car is started by electrifying at high voltage, if the remote high-voltage electrifying condition of the hybrid controller is not met, the keyless starting module receives a signal of 'remote high-voltage control state =1 (authentication failure)', or 'remote high-voltage control state =5 (charging gun insertion)', or 'remote high-voltage control state =3 (high-voltage fault exists)', or 'remote high-voltage control state =4 (clutch torque reliability is low)', which is sent by the hybrid controller, the keyless starting module sends a 'cause of failure request of the keyless starting module = remote high-voltage state failure' signal to the communication module, and then the communication module feeds back the signal to the mobile phone APP through the server; after the remote hot car is powered on and started at high voltage, if the remote high-voltage condition of the hybrid controller is not met, the keyless starting module receives a signal of ' remote high-voltage control state =5 (a charging gun is inserted), ' remote high-voltage control state =3 (a high-voltage fault exists), ' or ' remote high-voltage control state =4 (low clutch torque reliability) ' sent by the hybrid controller, the keyless starting module sends a ' cause of failure request of the keyless starting module = remote high-voltage state failure ' signal to the communication module, and the signal is fed back to the mobile phone APP by the communication module through the server; after the keyless start module receives a signal of 'remote start failure reason =1 (engine flameout condition exists/fuel quantity is too low)/3 (SOC is too low)' sent by the hybrid controller, the keyless start module sends the 'remote start failure reason' to the communication module, and then the communication module pushes 'hot car failure' to the mobile phone APP through the server.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.

step S23: and if the authentication between the keyless starting module and the hybrid controller is successful, starting the hybrid controller, otherwise, sending an authentication failure signal to the mobile terminal.
5. The method of claim 4, wherein the remote high voltage condition includes no battery management system failure, no battery insulation failure, and no battery crash.
6. The control method of a hybrid electric vehicle remote hot-car control system according to claim 5, wherein after the step S3 is completed and before the step S4 is executed, if the hybrid controller is in a remote control mode and the vehicle does not satisfy the remote high-voltage-on condition, the hybrid controller executes the high-voltage power-down procedure and feeds back the power-down signal to the mobile terminal, and stops executing the step S4.
7. The method of claim 6, wherein the power-up failure signal and the power-down signal comprise one or more of an unplugged charging gun, a high voltage fault, and a low clutch torque reliability.
8. The control method of the hybrid vehicle remote hot car control system according to claim 7, wherein the step S4 includes the steps of:
step S41: the hybrid controller collects vehicle information in the vehicle state module, the vehicle state module comprises a micro-control module, an engine control module, a gearbox control module, a shifter control module, an automatic clutch module, a battery management system and a power electronic module, if all modules in the vehicle state module are in a normal working state, the hot-car condition is met, and step S42 is executed, otherwise, the hot-car fails and the reason of the hot-car failure is fed back to the moving end;
step S42: the battery management system works to provide power for the whole vehicle system, and when the battery management system does not meet the vehicle heating condition and the engine system meets the vehicle heating condition, the engine is started to supply power for the whole vehicle system;
step S43: and judging whether the battery management system needs to be heated, if so, heating the battery pack by using the PTC thermistor, otherwise, stopping the work of the battery management system until the heating of the vehicle is finished.
9. The control method of a hybrid vehicle remote hot-car control system according to claim 8, wherein the hot-car failure cause comprises one or more of the presence of a trigger engine stall condition, too low fuel, too low battery.
