The invention discloses a control device for a linear electromagnet valve of an electric drive cooling system for a new energy automobile. The control device comprises an electromagnet valve control unit, a driving motor, a power generator, a water tank and the linear electromagnet valve, wherein the electromagnet valve control unit comprises a microprocessor, temperature sampling modules, a current sampling module and an electromagnet driving module. The microprocessor is used for determining control current of the linear electromagnet valve according to temperature data and current data whenit is judged according to the received temperature data that the linear electromagnet valve needs to be controlled; the temperature sampling modules are used for collecting coolant temperature of thedriving motor and coolant temperature of the power generator; the current sampling module is used for collecting actual current of the linear electromagnet valve; and the electromagnet driving moduleis used for controlling the opening degree of the linear electromagnet valve according to the received control current. By means of the control device, the control requirement of the electric drive system for the linear electromagnet valve in the cooling system is met, and under the circumstance of fluctuation of control parameters like the external environment, voltage, temperature of the electric drive system and the working condition, precise control over current and chattering current of the linear electromagnet valve of the electric drive cooling system is achieved.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicle control, and in particular relates to a linear solenoid valve control device for an electric drive cooling system of a new energy vehicle. Background technique [0002] With the shortage of energy and people's demand for environmental protection, electric vehicles have developed rapidly in recent years. As the "heart" of electric vehicles, the performance of the electric drive system directly determines the performance indicators of electric vehicles. As one of the key indicators of the performance of the electric drive system, the heat dissipation capacity directly affects the insulation capacity of the electric drive system, the strength and hardness of metal parts, the selection of electronic components and the working life. At present, electric drive cooling systems all use fixed-flow solenoid valves, which have high energy consumption and low work efficiency. Contents of the inv...
