Vehicle ventilation control method and device and vehicle

Abstract

The invention provides a vehicle ventilation control method and device and an automobile. The method comprises the steps that when a vehicle ignition switch is switched to an OFF gear or an ACC gear from an ON gear, a first power supply circuit for connecting a vehicle-mounted storage battery and an air conditioner air blower motor is disconnected, and a second power supply circuit for connectinga solar cell panel, a solar controller and an air conditioner air blower is connected; and when the solar controller monitors that the power supply voltage of the solar cell panel reaches the preset working voltage, the solar controller controls the solar cell panel to supply power to the air conditioner air blower. According to the invention, when the vehicle is switched from the ON gear to the OFF gear or the ACC gear, the relay is used for switching the power supply of the blower motor from the vehicle-mounted storage battery to the solar controller, and once the power generation intensityof the solar cell panel reaches a preset range, the blower motor is directly powered, so that the problems of energy consumption increase and power shortage of the storage battery in the prior art aresolved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle ventilation control method, device and automobile. Background technique [0002] In order to effectively use energy, the existing vehicles lay solar panels on the roof skylight, charge the battery through the solar panels, and then supply power to the vehicle air conditioning system by the battery. The air conditioning system controls the air conditioning blower to achieve rapid ventilation and cooling of the compartment Modules in the system that are not related to controlling the operation of the air conditioner blower will increase unnecessary energy consumption, and when the power produced by the solar panel is less than that of the vehicle battery to supply power to the blower, prolonged ventilation may cause the battery to lose power and affect the normal use of the vehicle. Contents of the invention [0003] The technical problem to be solved by the present...
