Abstract

The disclosure herein generally relates to vehicle control systems and more particularly, to a system and a method for controlling a powertrain for reducing power loss of a traction motor in the vehicle such as but not limited to an electric vehicle. The system (100) includes a main controller unit (102), a vehicle speed sensor (104), a throttle sensor (106), a control switch (108), a motor speed sensor (10S), a traction motor controller (10TMC) and a transmission controller unit (10TCU). The system optimizes the operating zone of the traction motor (10TM) for achieving better efficiency of the traction motor (10TM). The system reduces power consumption required for cooling battery and powertrain components of the vehicle due to less heat generation achieved by operating the traction motor (10TM) in higher efficiency zone.
