Abstract

The invention discloses a double-wheel hub electric vehicle Hall differential control system. The system comprises a control circuit power supply, an electric vehicle pedal governor, a left wheel hubmotor controller, a right wheel hub motor controller and an electric vehicle differential controller, the differential controller is internally sequentially fixedly connected with magnetic steel A, magnetic steel O and magnetic steel B, racks are arranged on the sides of the magnetic steel A, the magnetic steel O and the magnetic steel B, the ends of the racks are fixed to left Hall elements, theother ends are fixed to right Hall elements, the left Hall elements are located between the magnetic steel A and the magnetic steel O, the right Hall elements are located between the magnetic steel Oand the magnetic steel B, and the racks and a driving rotating shaft of a steering system of the electric vehicle are in drive connection. According to the above structure, the double-wheel hub electric vehicle Hall differential control system changes the distance between the Hall elements and the magnetic steel on the racks by the movement of the racks to change the intensity of the magnetic field of the magnetic steel on the Hall elements, and forms the output voltage inverse linear change of the Hall elements at both ends.

Description

technical field [0001] The invention relates to the technical field of steering control of a hub-type electric vehicle, in particular to a Hall differential control system for a double-hub type electric vehicle. Background technique [0002] With the rapid development of my country's electric vehicle market, hub-type electric vehicles have built-in drive motors in the hub, omitting the transmission system, and have the characteristics of high transmission efficiency and large vehicle space utilization, and have received extensive attention from the automotive industry. However, since in-wheel electric vehicles adopt distributed drive, traditional mechanical differentials cannot be used when steering. Generally, various parameters of the vehicle are measured by installing various sensors, and the vehicle mathematical model is input to calculate the required speed of each in-wheel motor. The output of the hub motor is controlled by the control system to achieve the differentia...
