Embodiment Construction

[0041] 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:

[0042] Determine whether the vehicle has a heat demand;

[0043] Detect the running status of the vehicle;

[0044] If the vehicle has heat demand and is in a static state, the high-frequency rotating magnetic field is generated inside the control motor, and the motor is locked at the same time.

[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 occupants; another example is the power battery, which needs an appropriate temperature to ensure the charging and discharging power.

[0046] At the same time, when the high-frequency rotating magnetic field is generated inside the motor, the stator current that g...

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; and if the vehicle has a heat demand and is in a static state, controlling the interior of the motor to generate a high-frequency rotating magnetic field, and meanwhile, locking the motor. The invention 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 control system. 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...
