Our department was established with the goal of enabling the team(s) supported by our developed powertrain to keep pace with other competitors operating with internal combustion engines, thus gaining an advantage over them. Thanks to the hybrid system, the vehicle can benefit from extra power during corner exits and straights, and torque vectoring provides additional rotation for the driver while cornering. In our parallel hybrid system, a single-cylinder internal combustion engine drives the rear wheels, while two high power density BLDC electric machines assist the front wheels as in-wheel motors. The speed of the high-revving electric machines is matched to the wheel rotation speed with the help of planetary gearboxes. In accordance with the regulations, the system can be powered by direct current up to 60 V, supplied by a battery pack with a maximum active energy storage of 3 kg. Our task is to integrate the hybrid system into the car, which includes designing and manufacturing the battery pack, developing engine control technology, building safety systems, designing and implementing the cooling system, designing and manufacturing the gearbox, integrating the electric machines into the car, system simulation, and vehicle testing.
