It also implements a comprehensive 3D model around the vehicle for automation operation, and provides reliable data even in bad conditions. Besides, V2X with M2XPro, which can identify the surrounding situation and communicate with the surroundings for automated driving, will create the basis for an automated driving environment by recognizing vehicle's position and movement at the same time.

▲ ADCU, at the center of automated driving implementation

▲ MK C1 HAD system combines MK C1 with MK100 HBE to create a redundant brake system.

▲ MK100 ESC High Plus Hybrid and Drum-Based Electric Parking Brake EPB-Si

The "Plan" area introduced 'Assisted & Automated Driving Control Unit (ADCU)', a central control unit that analyzes and evaluates various collected data and comprehensively generates the surrounding environment model. This enables a safe, versatile processing platform for applications in highly autonomous driving and plays an important role in interconnecting electric chassis and safety systems. Continental stated about the advantages of ADCU: scalability of its processing power and software modules, meeting safety requirements at maximum ASIL-D levels, possibility of integrating OEM black box software, and implementing the HAD environment model.

In 'Act' area, brake related systems were introduced. Among them, MK C1, introduced as the next-generation brake system, is an electric braking system that provides fast and accurate pressure rise by-wire, making it ideal for autonomous driving. MK C1 integrates the existing system's tandem master cylinder (TMC), brake booster and control system (ABS&ESC) into a single compact box package to lighten approximately 30% and increase the braking pressure within 150ms, which is twice as fast as the conventional one. Moreover, the design of electric brake can regenerate braking energy over a wider range than standard regenerative braking systems.

MK C1 HAD system architecture combines MK C1 system with an auxiliary brake system in the form of MK 100 HBE, enabling to stop vehicles even in the situation of a complete failure of the electronic main brake system. This can also provide an alternative for the user to stop a car when the main braking system fails in the implementation of the autonomous vehicle. Also, it is easily integrates into the existing MK C1 vehicle platforms, enabling the next step towards automated driving.

MK 100 ESC High Plus Hybrid is designed to combine the dynamic high pressure requirements of the automatic emergency braking function with the convenience requirements of the driver assistance function. This system, which makes use of both hydraulic brake and regenerative braking systems, can provide braking sense with reduced sense of difference in the hybrid system by appropriately applying the wheel braking and the deceleration by generator's regeneration of the power transfer unit according to the operation of the brake pedal. In addition, electric drum brake (EPB-Si) replaces the existing mechanical operations in drum brakes and provides key features of electric parking brakes to provide user convenience and interior design flexibility.
