Hyundai Mobis says it has become the first company in South Korea and the second in the world to successfully develop the next-generation electronic integrated regenerative brake system known as iMEB (Integrated Mobis Electronic Brake), for vehicles such as hybrid cars and EVs. 

IMEB, developed by Hyundai Mobis, is a brake system integrating the pressure supply unit and the pressure controller of the regenerative brake system into a single electronic system, reducing cost and weight by more than 30%. 

The company notes it is now also possible to integrate brake functionality, such as ESC (Electronic Stability Control), ABS (Anti-Lock Brake System), SCC (Smart Cruise Control) and AEB (Autonomous Emergency Braking). 

As the electronic version is able to transmit electric signals, unlike the hydraulic version which transmits power with which drivers activate brakes to trigger use of brake fluid, the system responds faster maintains Hyundai Mobis.

Hyundai Mobis develops an environment-friendly integrated electronic brake system

2015-11-20

- Electronically integrating a regenerative brake system for environment-friendly cars and state-of-the-art brake functionality, such as ESC and SCC 

- Reducing the weight and cost by nearly 30% compared to the existing separated systems…applying for 109 patents both domestically and abroad 

- Expecting to preempt the market for environment-friendly car brake systems and gain the upper hand in the competition for contracts

On November 22nd, Hyundai Mobis announced that the company became the first in Korea and the second in the world to successfully develop the next-generation electronic integrated regenerative brake system known as iMEB (Integrated Mobis Electronic Brake) for environment-friendly cars like hybrid cars and electric vehicles. 

iMEB, developed by Hyundai Mobis, is an advanced brake system that integrated the pressure supply unit and the pressure controller of the regenerative brake system into a single electronic system, and reduced cost and weight by more than 30%. It is now also possible to integrate cutting-edge brake functionality, such as ESC (Electronic Stability Control), ABS (Anti-Lock Brake System), SCC (Smart Cruise Control) and AEB (Autonomous Emergency Braking). 

As the electronic version is able to transmit electric signals unlike the hydraulic version that transmits the power with which the driver steps on the brakes to trigger use of the brake fluid, the brakes respond much faster, and thus braking performance can be maximized. 

As a core component of an environmentally-friendly car, the 'regenerative brake system' is a brake system that uses kinetic energy when the car stops to start the motor and charge the batteries. Through this mechanism, it can reduce the energydissipation rate by close to 70% compared to existing brake systems. In particular, it is an essential device for implementing environmentally-friendly cars in view of the fact that the regenerative system accounts for about 40% of the fuel efficiency improvement in hybrid cars over existing cars with internal combustion engines. 

In the existing 'regenerative brake system,' the 'pressure supply unit,' which amplifies the power with which the driver steps on the brake, and the 'pressure controller,' which calculates how much braking force will be applied to each wheel and controls it, are separated. So it is less competitive in terms of cost and weight. 

For this reason, all global automotive parts makers have recently engaged in developing electronic regenerative brake systems that integrate the pressure supply unit and the pressure controller. Functions implemented by several systems must be integrated into a single system, however, it is very difficult technologically. Accordingly, most companies are facing difficulties with developing this system. 

Overcoming this challenge, Hyundai Mobis became the second in the world to develop the electronic integrated regenerative brake system, thereby attracting a global spotlight. 

In particular, Hyundai Mobis is now able to further increase performance by developing the system electronically. Unlike the existing hydraulic version that transmits the power of the driver stepping on the brake through to the usage of brake liquid, the electronic version delivers better control as it transmits it directly through an electric motor.` 

Hyundai Mobis, a late starter in brake systems, was able to acquire the core technology for environmentally-friendly cars ahead of other makers due to its insightful and strategic savvy. The company opted to forgo developing the separated regenerative brake system, which other companies were developing intensively, and began to develop an advanced integrated regenerative brake system earlier than others. In this process, Hyundai Mobis applied for a total of 109 patents including 20 overseas patents. 

As Hyundai Mobis was able to secure advanced technology ahead of its competitors, it is expecting to capitalize on iMEB to gain the upper hand in competition for contracts related to environmentally-friendly brake systems. The integrated regenerative brake system has been developed by only a few makers around the world and the market still remains as a blue ocean market as the technology has not been applied to mass-production vehicle models as of yet. 

As for brake systems, the iconic safety device in the automotive industry, contracts tend to last long once they are signed. So it seems that if Hyundai Mobis succeeds in winning orders, it will be able to enjoy the preemptive effect in the brake system market for environmentally-friendly cars. Furthermore, as iMEB is a high value-added part that integrates a variety of state-of-the-art brake features, once the contract is signed, several core parts will be supplied at the same time. 

"At a time when environmentally-friendly cars are replacing automobiles with internal combustion engines, preempting the high value-added parts market for environmentally-friendly cars is equal to gaining a new growth engine for the future," said Jeong Seung-gyun, head of the R&D Division of Hyundai Mobis. "We will further reinforce our investments in R&D for the core parts ofenvironmentally-friendly cars and secure many high value-added products like iMEB." 

Meanwhile, Hyundai Mobis is strategically developing various environmentally-friendly parts such as in-wheel systems and low-voltage hybrid systems besides iMEB. Hyundai Mobis is planning to actively engage in sales activities with the core parts of these environmentally-friendly being the center of focus, and preempt the parts market for environmentally-friendly cars.
