Problems solved by technology

[0002] In related technologies, the fault detection and protection functions of the motor control system of electric vehicles are in charge of the control chip of the motor control system, which increases the load on the control chip. Therefore, in the case of various and complex driving conditions of electric vehicles, The speed and accuracy of the fault detection and protection of the control chip for the motor control system will become lower, which reduces the safety and reliability of the motor control system

Abstract

The invention discloses an electric vehicle and a motor control system thereof. The motor control system comprises a driving module connected with the motor of the electric vehicle to drive the motor;and a main control module, wherein the main control module comprises a control chip and a programmable logic device, the programmable logic device is connected with the driving module and the controlchip is connected with the programmable logic device. Therefore, a hardware protection circuit independent of the control chip is arranged so that the fault detection and protection of the motor control system can be performed quickly in real time and quickly and the safety and the reliability of the motor control system can be improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electric automobile and a motor control system thereof. Background technique [0002] In related technologies, the fault detection and protection functions of the motor control system of electric vehicles are in charge of the control chip of the motor control system, which increases the load on the control chip. Therefore, in the case of various and complex driving conditions of electric vehicles, The speed and accuracy of the fault detection and protection of the motor control system by the control chip will become lower, which reduces the safety and reliability of the motor control system. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the first purpose of the present invention is to propose a motor control system for electric vehicles. By s...
