Title:
ELECTRONIC BRAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/167007
Kind Code:
A1
Abstract:
An electronic brake system (1), used in an electric vehicle. The electronic brake system comprises a controller (10) mounted to the electric vehicle, a storage battery (20) connected to the controller (10), a rechargeable battery (30), a brushless motor (40), and multiple Hall elements (50) used to monitor a relative position of a stator to a rotor of the brushless motor (40). The controller (10) has the following circuit units: an analog-to-digital conversion unit (101) used to convert an analog value of a signal acquired by the Hall elements (50) into a digital value; an acquisition unit (102) used to acquire a normal drive signal and/or a brake signal; a brake adjustment unit (103) used to send a de-energization signal and a signal requesting the multiple Hall elements (50) for reverse rotation upon receiving of a brake signal acquired by the acquisition unit (102); and a motor drive unit (104) used to perform, upon receiving of the de-energization signal and the signal requesting the multiple Hall elements (50) for reverse rotation, digital/analog conversion and braking, such that the brushless motor (40) stops operation. The electronic brake system enables fast braking.
