The invention provides a direct current motor controller controlled by a single chip microcomputer and relates to automobile control devices, particularly to a control device and method applied to the separated excitation direct current motor armature and excitation of an electric vehicle. According to the direct current motor controller controlled by the single chip microcomputer and the control method thereof, the single chip microcomputer is sufficient in supply, the cost is low, the signal control method is advanced, various control circuits are separated from sensors through the direct current motor controller to ensure that the control circuits can be undisturbed to perform the mode conversion processing on signals of the sensors, meanwhile every sensor is separated to be converted into a single sensor from a compound sensor to effectively avoid the interference of electromagnetic signals, and accordingly the problems of other chip control devices are effectively solved.
Description
technical field [0001] The invention relates to an automobile control device and a control method thereof, in particular to a control device and a control method for the armature and excitation of a separately excited DC motor for an electric vehicle. Background technique [0002] With the popularization of new energy vehicles, more and more small vehicles (golf carts, sightseeing cars, patrol cars, etc.) It occupies a large share in the small electric drive market. At present, the main control chip of most separately excited DC motor controllers adopts microcontrollers from foreign manufacturers, which have high cost, unstable supply, inappropriate signal processing methods, and cannot output corresponding fault codes or fault judgment information externally. Unreasonable and prone to electromagnetic signal interference. In addition, in the control mode of the controllers of many other manufacturers, as long as a fault occurs, it will be shut down immediately (flame out p...
