Nissan announces two world first technologies – Electro-hydraulic Power steering system and Electric Driven Intelligent Brake systems
Nissan today announced two world first technologies – Electro-hydraulic Power steering system and Electric Driven Intelligent Brake systems. 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.
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. The new systems will be mounted on the Nissan Fuga Hybrid, which goes on sale in Japan this fall, and Infiniti M Hybrid, a luxury hybrid model scheduled to be launched in 2011 in the United States and Europe.
