Problems solved by technology

[0002] On-board air conditioners are a very important part of vehicle energy consumption. When the on-board air conditioners of traditional passenger cars are turned on in the cooling mode, they need to manually turn on the engine speed boost mode in advance, so as to drive the air conditioner compressor and the air conditioner dedicated generator to rotate at the same time. In order to achieve an effective cooling effect, if the car air conditioner is always in the cooling mode, even when the temperature inside the car reaches the set temperature, the engine will not stop automatically. Economical fuel consumption is greatly reduced

Embodiment 1

[0033] An air-conditioning control circuit for a plug-in hybrid electric bus, including a vehicle controller 1, which collects a compressor control signal and an engine state signal of the vehicle-mounted air conditioner, and is used to control the start and stop of the vehicle-mounted air conditioner 2 and the engine 3: The enabling output end of the vehicle controller 1 is connected to the enabling end of DC / DC5; the high-voltage power supply input end of DC / DC5 is connected to a high-voltage battery 6, and the voltage of the high-voltage battery 6 is at least higher than 500V; When the compressor stops running, the vehicle controller controls the DC / DC5 to start working at the same time, converting the high-voltage power supply to 24V voltage output.

[0034] like figure 1 Shown: a plug-in hybrid passenger car air conditioning control circuit, including the vehicle controller 1, vehicle air conditioner 2, engine 3, 24V generator 4, DC / DC5, high voltage battery 6, 24V batter...

Embodiment 2

[0049] A plug-in hybrid electric passenger car adopts the air-conditioning control circuit of the plug-in hybrid electric passenger car.

Embodiment 3

[0051] An air conditioning control method for a plug-in hybrid electric bus, comprising:

[0052] Set the target temperature T and T of the car air conditioner 1， T QUOTE T 1 ;

[0053] When the temperature inside the vehicle is higher than the target temperature T, the on-board air conditioner is started to carry out the cooling process with the target temperature T, and the vehicle controller starts the engine to work according to the control signal of the air conditioner compressor, and the engine simultaneously drives the compressor in the on-board air conditioner and the The 24V generator is running; the engine is prohibited from idling and shutting down; the DC / DC does not perform the conversion of high and low voltage power supply during the cooling process;

[0054] When the temperature inside the car reaches the target temperature T, the compressor inside the car air conditioner stops running, the engine returns to idle stop mode, and at the same time, the DC / D...

Abstract

The invention relates to an air conditioner control circuit and method for a plug-in hybrid power bus. The control circuit comprises a vehicle controller, compressor control signals of a vehicle-mounted air conditioner and engine state signals are collected through the vehicle controller for controlling starting and stopping of the vehicle-mounted air conditioner and an engine; the enable output end of the vehicle controller is connected with the enable output end of a DC / DC converter; and the high-voltage power supply input end of the DC / DC converter is connected with a high-voltage battery, and the voltage of the high-voltage battery is at least higher than 500 V. When a compressor in the vehicle-mounted air conditioner stops operating, the vehicle controller controls the DC / DC converter to start to work at the same time, and a high-voltage power supply is converted into 24 V voltage to be output.
