Intelligent alarming anti-theft brushless controller for electric vehicle

Abstract

The invention relates to an intelligent burglar alarm non-brush controller used in electric vehicle, wherein said controller comprises a burglar alarm signal generating circuit, a Hall signal processing circuit, a control circuit with microcomputer, and a motor driving circuit; the operation of microcomputer comprises following steps: (1) detecting if the burglar signal generating circuit inputs burglar alarm state signal, or else outputting driving control signal based on general sequence; (2) detecting if the Hall signal processing circuit inputs motor rotation signal, or else continuously executing this step; (3) outputting driving control signal reversed to general phase; therefore, the motor driving circuit can generate reversed torque when there is burglar, to lock the motor until the external torque is eliminated to guard the vehicle effectively.

Description

technical field [0001] The invention relates to an anti-theft control device, in particular to an intelligent alarm anti-theft brushless controller for electric vehicles, belonging to the technical field of electric vehicles. Background technique [0002] Along with popularizing of electric bicycle, moped, the anti-theft of this type of electric bicycle becomes the problem that people pay close attention to. It is understood that the main anti-theft measures for electric vehicles are still to install various anti-theft locks. Though these anti-theft locks are increasingly ingenious, such as the electronic control anti-theft lock disclosed in 200420108845.4 Chinese patent, there are anti-theft locks with higher technical content, which increases the difficulty of picking the lock, but as long as the lock is destroyed, the vehicle may still be stolen. [0003] The application number is 02261079.0 and the title is "An Anti-theft Alarm Device for Controlling Electric Bicycle Pe...
