Double-character electronic gear electric tricycle driving device and driving method

Abstract

The invention discloses a double-character electronic gear electric tricycle driving device. The double-character electronic gear electric tricycle driving device comprises a duplex winding efficient differential motor, an intelligent electronic gear controller and a switching relay; the intelligent electronic gear controller comprises a motor driving circuit and an electronic gear shifting circuit; three phase output ports A, B and C of the motor driving circuit are respectively connected with high speed windings A, B and C and low speed windings A1, B1 and C1 of the duplex winding efficient differential motor through the switching relay; a fifth pin of a control signal output end JP1 of the electronic gear shifting circuit is connected with control ports JVCC and JGND of the switching relay. According to the double-character electronic gear electric tricycle driving device, a mechanical gear speed changer is saved, full automatic electronic speed changing is achieved through the intelligent electronic gear controller according to different driving road conditions, and accordingly the electric tricycle has large torque and high speed comprehensive performance, the electric tricycle can maintain high working efficiency during driving under the different road conditions, the endurance mileage and the climbing capability of the vehicles are increased, energy is saved, and performance of the electric tricycle is greatly improved.

Description

technical field [0001] The invention relates to an electric transmission control system of an electric tricycle, in particular to an electric tricycle drive system. Background technique [0002] At present, domestic electric tricycles are generally driven by a single-winding differential motor and a single-speed controller. This type of driving mode has a single electrical characteristic, and there are the following three situations: First, when the efficiency characteristics of the motor are suitable for driving on flat roads, Driving on flat roads has high efficiency and long cruising range; but when driving on hilly roads, the torque is insufficient and the efficiency is extremely low, which seriously affects the cruising range and climbing ability; When driving on the road, it causes excess torque, slow speed and low efficiency; third, in order to take into account both flat road driving and slope road driving, it is usually necessary to install a mechanical gear transmi...
