Abstract

The invention provides switching application of intelligent cruising of a hub self-sliding motor for an electric automobile and control over PWM and SVPWM of a permanent-magnet brushless motor. According to the switching application, an electric intelligent cruising controller with an automatic sliding function and the permanent-magnet brushless BLDCM motor are used for achieving automatic and manual switching of 120-degree two-phase breakover PWM square wave control and 180-degree three-phase breakover SVPWM sine wave control.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control system for electric motors used in electric vehicles. Background technique [0002] At present, there are many types of electric motors used in electric vehicles, each with its own advantages and disadvantages, and it is the general trend to replace the mid-mounted motor with hub motors. The high-efficiency and energy-saving self-sliding technology of hub motors has the advantage of being a latecomer. However, there is no research on the control of motor self-sliding. When the car is going uphill, it is easy to use the self-glide function by mistake. When it should not be used, the driver often forgets to use the self-glide function when the car is on a straight road. It is useless when it should be used. The best time to use the self-glide function is when going downhill. However, the driver is often unable to control the length of the taxiing time. On downhi...
