MK C2
The MK C2 is Continental’s second-generation brake-by-wire system and will enter series production in 2022.
- Reduction of 5g of CO2 per KM according to WLTP testing, when compared to a conventional system
- Innovative architecture supports use of true zero-drag calipers, further decreasing emissions
- 100% efficient regenerative braking system
- Multi-logic architecture supports parking-pawl removal for EV and Valet parking
- Simplified design allows reduction in size, weight, and number of components compared to MK C1
- Significantly faster buildup of autonomous braking pressure than conventional hydraulic systems
- Reduced logistics and installation effort during car production
MOTION CONTROL
Motion Control is a key element in assisted and autonomous driving functions. It transforms the driving plan into lateral and longitudinal actuator commands.
- Support of motion requests on trajectory level or on vehicle dynamics level for assisted/autonomous driving functions
- Control the vehicle motion in lateral and longitudinal direction
- Enhanced interaction with agility and stability functions for improved safety and performance
- Decoupling of functions layer from actuators layer by providing a lean and coherent interface
- Handling of driver interaction and shaping the driving experience
- Allocation of control commands to different actuators - like brake, powertrain, steering - taking into consideration their performance capabilities and limitations
- Flexible and modular with respect to different actuator interfaces
- Scalable and multi-platform portable AUTOSAR software components
- Easily applicable through model-based control
