Nissan is introducing two new technologies, “Electro-hydraulic Power Steering system” and “Electric Driven Intelligent Brake” systems, which will be first tested in some Japan-only models before they become available for the rest of the world. The Electro-Hydraulic steering system is actually the modern production form of an old idea to use electric motors for power steering, and as for the Intelligent brakes, they are similar to brake assist system, but again uses electric motors to operate the brake cylinders.

Electro-hydraulic Power Steering system
For the first time in the world, an Electro-hydraulic Power Steering system has been adopted in which the motor is activated only when the driver is steering. The system is smaller than traditional power steering systems, which was achieved by integrating multiple parts. It offers the advantages of both types of steering – the natural and smooth steering of hydraulic power steering and the improved fuel efficiency of electric power steering – combined to create a balanced system fitting the Nissan Fuga and Infiniti M’s luxury sport sedan buyers’ needs.

Electric Driven Intelligent Brake
The Electric Driven Intelligent Brake, another world’s first system, utilizes the vehicle’s electric motor to directly operate the brake cylinders. When the driver steps on the brake pedal, the necessary braking force is maintained while the hydraulic pressure of the friction brake is controlled to help maximize the energy regeneration of the hybrid motor. Because of its simple structure, in which the motor directly operates the brake cylinders, this new Electric Driven Intelligent Brake system has the potential to be applied to various future hybrid vehicles.

Nissan’s goal is to achieve superior environmental performance while pursuing a fundamental quality of its cars – the joy of driving. The hybrid drive system to be used on the Fuga and Infiniti M Hybrids consists of the gasoline engine, electric motor and a unique Intelligent Dual Clutch Control utilizing separate electronically-controlled clutches on the drive wheels. This allows high environmental efficiency, while achieving an exhilarating driving experience with high-response linear acceleration levels that equal or exceed those of gasoline-powered cars.

These technologies are the culmination of the company’s research and development efforts based on the Nissan Green Program 2010 (NGP 2010) – Nissan’s mid-term environmental action plan that includes initiatives to reduce CO2 emissions and introduce truly effective technologies, products and services into the market.
