Problems solved by technology
[0004] The existing vehicle controller controls the motor controller mainly by analyzing the driver's acceleration or braking requirements. The problem is that it does not refer to the current state of the battery pack and the current state of the motor at the same time, and does not realize human-computer interaction. ;Causing overcharging and overdischarging of the battery pack, and damage to the motor; and the obtained torque is not the minimum value, resulting in a waste of energy

The invention relates to a man-machine interaction motor drive torque management system for battery electric vehicles and a method thereof. The system comprises a driver demand detection module, a battery pack status detection module, a motor status detection module, a controller and a motor drive module; wherein the driver demand detection module, the battery pack status detection module and themotor status detection module are respectively and electrically connected to the controller; and the controller is electrically connected to the motor drive module. The management method comprises thefollowing steps: 1. The driver demand detection module detects driver demands in accelerating or braking; 2. The battery pack status detection module detects statuses about battery state of charge (SOC), direct current, battery single cell voltage and battery pack total voltage. The invention can control a motor controller by comprehensively analyzing the driver demands in accelerating or brakingand taking the current statuses of a battery pack and a motor into consideration, thereby realizing man-machine interaction.
Description
technical field [0001] The invention relates to the field of pure electric vehicle control, in particular to a pure electric vehicle human-computer interaction motor drive torque management system and method. Background technique [0002] With the rapid development and popularization of automobiles in our country, the issue of energy saving and emission reduction of automobiles has become more and more important. Although the current electronic control technology of internal combustion engines and the application of exhaust purification technologies such as three-way catalysis have reduced the emission and fuel consumption of automobiles to a very low level, it is impossible to fundamentally solve the emission and energy problems of automobiles. Electric vehicles are the best way and way to solve this problem. Major automobile manufacturers and research institutes across the country have invested a lot of human and financial resources in the research and production of new e...
