Electric Driven Intelligent Brake System By Nissan


Nissan has announced two innovative technologies for its upcoming Hybrid Nissan Fuga. We have already covered the first one – Electro Hydraulic Power Steering System. In this post I will share the second equally interesting innovation called the Electric Driven Intelligent Brake System.

What Is Electric Driven Intelligent Brake System ? How Does Electric Driven Intelligent Brake System Work ?

Before I tell you how this Electric Driven Intelligent system works, I would like to briefly tell you how a conventional Power Brakes System Works. Most of the power brake systems derive vacuum from the engine intake manifold and use this energy to apply brake force which greatly reduces driver’s pedal force and brakes become highly responsive and easy to operate. One major disadvantage of this system is that it puts load on the engine since the braking energy is extracted from the engine. Also the energy lost in stopping the car almost all goes waste in conventional braking systems.

In the Electric Driven Intelligent Braking System, the braking force is provided with the help of a ECU controlled motor and ball screw arrangement. This means that no direct load on the engine while applying brakes. This means that a motor operated the brake for providing the braking energy. A more controlled and uniform braking force is applied since its ECU controlled, this helps to recover braking losses when a regenerative braking system is used.

Below is an extract from the official press release :

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.
