Title:
DRIVING SYSTEM AND METHOD FOR BATTERY ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2016/065672
Kind Code:
A1
Abstract:
A driving system (100) for a battery electric vehicle comprises a motor driver (110), a brushless direct-current motor (120), a continuously variable transmission (130), a whole-vehicle controller (163), a motor controller (161), and a variable speed controller (165). The brushless direct-current motor (120) is internally provided with a first group of sensors used for separately measuring part of the following parameters: a rotating speed, a voltage and a torque. An input end of the motor controller (161) is connected to the first group of sensors. The continuously variable transmission (130) is internally provided with a second group of sensors used for separately measuring part of the following parameters: a clutch, rotating speeds and pressures of a driving wheel and a driven wheel, and a gear position switch. The whole-vehicle controller (163) acquires a group of parameters in real time, comprising an ABS vehicle speed signal, an acceleration pedal main driving signal, a brake signal, a motor rotating speed and a load current, and determines the working condition of the battery electric vehicle according to the group of parameters and determines a variable speed ratio and a variable torque that correspond to the working condition, and instructs the variable speed controller (165) to control a gear shift executor (136) to execute.
