Problems solved by technology

[0002] The air-conditioning condenser of engineering vehicles mostly dissipates heat through the fan of the engine. When the air conditioner is turned on at idle speed, the condenser’s heat dissipation capacity is poor, resulting in high pressure on the air-conditioning system, which easily damages the compressor. Specifically, at idle speed, through condensation The wind speed in front of the condenser is small, and the heat dissipation of the condenser is poor, which will lead to an increase in the pressure of the air conditioning system
In response to this situation, the existing engineering vehicles have opened the air conditioner idle speed boost function, that is, when the air conditioner is turned on at idle speed, the speed of the engine fan is increased, thereby improving the heat dissipation capacity of the condenser and reducing the pressure of the air conditioning system. The pressure of the system is used to automatically control the speed of the fan, and the fuel consumption is high

Abstract

The invention provides a vehicle control system, a vehicle and a control method. The vehicle control system comprises an engine, a rotating speed sensor, an air-conditioning system, a pressure sensor,a fan and a control terminal, wherein the rotating speed sensor is used for detecting the rotating speed of the engine; the pressure sensor is arranged on the air-conditioning system so as to detectthe real-time pressure of the inside of the air-conditioning system; the fan is connected with the engine, driven by the engine and used for cooling the air-conditioning system; and the control terminal is electrically connected with the rotating speed sensor, the pressure sensor and the fan and further used for controlling the fan to operate through the engine according to the real-time pressure.By adoption of the technical scheme, the rotating speed of the fan can be automatically and flexibly regulated through the engine according to the actual condition of the air-conditioning system, andtherefore on the premise that the cooling effect of the fan is guaranteed, energy consumption can be reduced and energy can be saved.
