Next-gen brake system is optimized for future E/E architectures
With the second generation of its electrohydraulic brake system, Continental wants to score points especially with electric vehicles and automated driving. The MK C2 is more compact than its predecessor. Plus, its multi-logic architecture is designed to enable new vehicle features.

The MK C2 is smaller and lighter than the currently offered model. Nevertheless, it offers higher availability and better performance and new functions, Continental promises. It is said to be easier to integrate into smaller vehicle models and complete vehicle platforms with different drive concepts and installation space conditions. The vehicle-specific application has also been simplified. It contains fewer components, which has a beneficial effect on costs. The transition to a multi-logic architecture with two independent partitions and thus a redundant fallback level increases system availability, especially with regard to automated driving. Among other things, MK C2 already offers the brake functionality for highly automated valet parking as a basic system.

Like MK C1, the new brake is a "brake-by-wire" system in which the brake pedal is decoupled from the actual pressure generation. This opens up advantages that are becoming increasingly important in new vehicle designs: In a normal driving style, electricity can be generated by recuperation in more than 80 % of all deceleration situations in an electric car. For the driver, the brake pedal should always feel the same, even though the wheel brakes are not applied at all. In automated driving, on the other hand, the MK C2 with its very high dynamics can build up brake pressure in just 150 ms as soon as the automation or an assistance system requests it - this also happens without the driver being unsettled by a pedal reaction. The MK C2 is designed for automated driving according to SAE Level 3 or higher.

With an additional hydraulic brake extension as a redundant fallback level, the MK C2 is designed for highly automated driving.

Future braking systems must be able to do more than just decelerate the vehicle safely. They must also contribute to the efficiency of the vehicle - and they must meet new requirements for automated driving. This includes providing highly
