Problems solved by technology
[0004] The existing vehicle air conditioner remote control technology requires the vehicle controller VCU to receive the remote control command sent by the T-box first, and then the VCU analyzes it and then sends the control command to the PTC controller. The VCU is responsible for information interaction and control The center of the system, the signal interaction process is longer, which increases the probability of communication errors and the static power consumption of the vehicle's low-voltage battery
And in the process of this control method, the vehicle controller VCU is in a fully activated state, that is, the vehicle is in a fully activated state, which may easily cause vehicle misoperation or unrelated personnel to enter the vehicle, posing safety risks

The invention discloses a remote safety control system and method for a vehicle-mounted air conditioner of a new energy automobile. The system includes a mobile terminal in remote communication connection with a T-BOX; the T-BOX is connected with a PTC controller through a CAN line; the PTC controller is in communication connection with a battery management system (BMS) through a CAN line; the BMSis in communication connection with a main negative relay, a pre-charging relay and a main positive relay; and the PTC controller is connected with an air conditioner control system CLM and a motor controller MCU through CAN lines. According to the invention, during periods of remote heating control starting and heating removing of the air conditioner, the PTC controller is in a remote control mode and temporarily takes over the control function of part of the VCUs; for example, a battery connection and disconnection command is sent to the BMS, an active discharge mode entering command and asleep mode entering command are sent to the MCU; and after the PTC controller exits from the remote control mode, parts of control functions of the VCU are not achieved. Therefore, control chaos caused by intersection of the control functions of the PTC controller and the VCU in the normal driving process is avoided.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicles, and more specifically, the invention relates to a remote safety control system and method for a vehicle-mounted air conditioner of a new energy vehicle. Background technique [0002] Different from traditional fuel vehicles that use engine waste heat to heat the interior passenger compartment, new energy vehicles use PTC controllers and cooperate with CLM (air conditioning control system) to heat the air in the passenger compartment to meet the needs of interior heating and defrosting and defogging. [0003] In the cold season, when the vehicle is just started and the air conditioner is turned on, the temperature in the passenger compartment will not immediately reach a comfortable temperature. Therefore, the realization of the remote air conditioner heating function of new energy vehicles can make the passengers in the car have a better driving experience in winter feel. In new ener...
