Control system of dual-drive electric automobile

Abstract

The invention relates to a control system of a dual-drive electric automobile, comprising a power supply and indicating / illuminating lamps. The control system is characterized by comprising a front controller and a rear controller which respectively drive and are connected with a front drive differential motor and a rear drive differential motor; moreover, the front controller and the rear controller are respectively provided with an accelerator and connected with the Hall sensor of the permanent magnet rotor of an induction motor; each differential motor comprises a gear box and a brushless high-speed motor; the gear box comprises a speed change structure and a differential; the differential comprises a planet carrier, a planet gear and a half axle gear; the high-speed motor drives and is connected with the planet carrier by a transmission shaft, drives the half axle gear by the planet gear and respectively drives and is connected with left wheels and right wheels; the front drive controller controls the automobile to work on a flat pavement; and the drive controller is started to increase the power and the output torque of the motor when clamping a slope, thus realizing the energy-saving effect. The motor and the speed change structure have the advantages of high efficiency, low temperature increase and large torque; the large torque output greatly improves the service life of the accumulator of the electric automobile and prolongs the charging period; therefore, the control system has high practicality.

Description

technical field [0001] The invention relates to a control system of a dual-drive electric vehicle. Background technique [0002] The control system structure of the existing electric vehicles is simple, generally a single-drive control structure controls the front and rear drives at the same time, instead of a dual-drive control structure, so that the horsepower of the electric vehicle is insufficient when climbing a hill, or the charging cycle of the battery of the electric vehicle is too short . Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a control system for a dual-drive electric vehicle, which has a large vehicle torque, a long charging cycle, and a very good energy-saving effect. [0004] The technical solution provided by the invention is that the control system of the dual-drive electric vehicle includes: [0005] Battery power supply, which can provide working power for the system; ...
