Lexus Hybrid Drive System Architecture
The Lexus CT 200h's second generation full hybrid system features a 1.8 litre petrol engine, a powerful electric motor, a 42kW generator, a high performance, 202V, 27kW battery, a power control unit, and a power split device which employs a planetary gear set to combine and reallocate power from the engine, electric motor and generator according to operational requirements.
The electric motor, generator and power split device are all housed in one lightweight, highly compact transmission casing directly comparable in size to that of a conventional gearbox. Drive to the front wheels is provided by the full hybrid system's seamless, Shift-by-Wire, electric continuously variable transmission.
The lightweight, highly-compact, 16-valve, DOHC, 1,798cc Atkinson Cycle VVT-i incorporates a cooled Exhaust Gas Recirculation (EGR) system and a third generation exhaust heat recovery system. It generates 99 DIN hp/ 73kW at 5,200rpm and 142Nm of torque at 4,000rpm. The high performance, permanent magnet, synchronous 82 DIN hp/60kW electric motor generates 207Nm of torque from 0 rpm.
The electric motor works in tandem with the petrol engine to boost acceleration and power the driven wheels alone when the Lexus CT 200h is operating in EV mode.
During deceleration and under braking, the electric motor acts as highoutput generator to effect regenerative braking.
When operating in a switchable EV mode, the new Lexus full hybrid generates zero emissions, driving for up to two kilometres at speeds of up to 45km/h.
