Proton unveils prototype Hybrid Car Developed In Collaboration With Lotus

A sophisticated control system was developed to implement the energy management function by monitoring and controlling all sub-control systems including the engine management, motor/generator, transmission, HVAC, additional clutch, starter/alternator and battery pack.

To maintain the integrity of the braking circuit when the petrol engine is off, a Mes-Dea electric vacuum pump maintains the power assistance for the brakes.

A TRW electro-hydraulic power assisted steering pump has been fitted, allowing the retention of the existing steering column and hydraulic steering gear. This pump also provides hydraulic pressure for the additional clutch that engages the hybrid motor.

The instrument panel incorporates an additional LCD display developed by Lotus Engineering to show battery charge, power split between engine and motor, fuel economy and charge/discharge rate, and incorporates associated warning indicators where appropriate.

The dash is also fitted with new switches to select the car's operating mode - micro hybrid, full hybrid or full electric vehicle.
