Embodiment Construction

[0040] figure 1 It is a flow chart of a motor active heating control method for a vehicle according to an embodiment of the present invention. Such as figure 1 As shown, the motor active heating control method for the vehicle includes:

[0041] Determine whether the vehicle has a heat demand;

[0042] Detect the running status of the vehicle;

[0043] If the vehicle has heat demand and is in a static state, the direct axis current of the control motor is DC current, and the quadrature axis current of the control motor is zero;

[0044] Wherein, when the direct axis current of the motor is DC current and the quadrature axis current of the motor is zero, a constant magnetic field parallel to the rotor magnetic field of the motor is formed inside the motor, and the motor has no torque output.

[0045] Here, the heat demand refers to the place on the vehicle that needs heat, such as the passenger compartment, which needs to increase the temperature to ensure the comfort of the...

Abstract

The invention discloses a motor active heating control method and system for a vehicle and the vehicle, and relates to the technical field of vehicles. The motor active heating control method for thevehicle comprises the steps of judging whether the vehicle has a heat demand or not; detecting the running state of the vehicle; if the vehicle has a heat demand and is in a static state, controllingthe direct-axis current of the motor to be direct current, and meanwhile, controlling the quadrature-axis current of the motor to be zero, wherein when the direct-axis current of the motor is direct current and the quadrature-axis current of the motor is zero, a constant magnetic field parallel to the rotor magnetic field of the motor is formed in the motor, and the motor has no torque output. Theinvention further provides a corresponding control system. Meanwhile, the invention further provides a vehicle which adopts the control method to control heating of the motor or comprises the controlsystem. When the whole vehicle is static, the motor can generate enough heat to meet the heat requirement of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a motor active heating control method and system for a vehicle and a vehicle. Background technique [0002] With the development and progress of society, electric vehicles, as an environmentally friendly means of transportation, have the advantages of economical operation, clean and environmental protection, etc., and their application range has become wider and wider. [0003] At present, the driving system and thermal management system of electric vehicles are realized by different components, and the functions between the two are relatively independent without multiplexing. Contents of the invention [0004] The inventors of the present application have found that the vehicle drive system is mainly used to provide driving force, and in consideration of increasing the cruising range as high as possible, the design and control of the motor is mainly aimed at the high efficien...
