Hyundai Mobis says it has developed a new safety brake system optimized for fully autonomous driving, Level 4 or higher. With the company’s redundancy brake system, the emergency brake system is activated by itself, even if the brakes do not work normally due to failure of electrical devices or external shock.

The redundancy brake system is intended to proactively prepare for Level 4 or higher fully autonomous driving. If the redundancy brake system of Hyundai Mobis is applied, the auxiliary brake system is activated in an emergency situation. The system consists of two electronic brake systems, the ECU, which is the brain for controlling the systems, and the software control platform.

At usual times, the two controllers are connected to each other and exchange data, but if the main brake system is not working normally, the controller detects it and orders the auxiliary brake system to start working. The core of this technology is to develop the software platform to help the control make a correct judgment at this time.

The company says that developing the redundancy brake system was a challenging process because "it is difficult to implement precise hardware technology and the software for controlling the two systems." According to Hyundai Mobis, it is the first company to successfully develop the redundancy brake system at a level that can be immediately applied to passenger cars or SUVs.
