Hyundai Mobis develops redundant braking system for autonomous vehicles

Hyundai Mobis has developed a new safety brake system optimized for Level 4 autonomous driving. The ‘redundancy brake system’ is activated when the brakes malfunction due to the failure of electrical devices or external shock.

As autonomous driving evolves to a higher level, the intervention of the driver decreases, and it becomes essential to secure the precision safety technology in preparation for an emergency situation. Accordingly, active efforts to develop redundancy technologies in automotive parts such as the brakes is key.

The redundancy brake consists of two electronic systems: the ECU, which is the brain of the system,; and the software control platform. During normal driving, 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. During autonomous driving, numerous variables, which perceive external environments, must be taken into consideration.

Hyundai Mobis claims that 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.
