What is Vehicle Motion Control (VMC)?
What is Vehicle Motion Control (VMC)?
Software-based control: VMC is a software solution that converts the planned movement and/or driver input into actuator signals. The decision on how to realize the vehicle motion is calculated on the basis of measured and estimated key figures as well as defined targets and priorities for certain settings.
Optimal driving dynamics: VMC influences the lateral, longitudinal and vertical dynamics of the vehicle and enables intelligent control of vehicle movement.
Integration of systems: At the heart of future vehicle architectures are powerful central or domain control units on which the central software, including VMC, runs. For VMC, the chassis with the four main actuators - steering, brakes, drivetrain and dampers - are the degrees of freedom for realizing the vehicle movement.
How does Vehicle Motion Control work?
How does Vehicle Motion Control work?
Our Vehicle Motion Control focuses on the performance level of the vehicle. This means that perception with sensors, cameras, etc. and data processing for trajectory planning are input data for VMC. VMC concentrates on control, i.e. the software decides how the vehicle movement should be realized based on various conditions and target functions and defines the corresponding commands for the actuators.
The main modules of Vehicle Motion Control are the reference generator, the controllers and the control mapping, the heart of VMC. An automated driving interface or an interface to a manual driver can be used as the input source. As soon as VMC receives the desired vehicle behavior from one of these interfaces, the actuator and movement reference is generated as the basis for calculating the control system. The “Control” module contains all the high-level functions required to implement the vehicle movement. Examples of this are stability control, automated parking or cruise control. The control assignment as a common interface between actuators and controls translates the defined vehicle movement into the corresponding actuator signals.
Why Vehicle Motion Control (VMC)?
The automotive market is undergoing rapid change with the advent of electrification and trends such as software-defined vehicles. Against this backdrop, we see strong demand for a software solution that centralizes functions right up to high-level actuator software.
Only with solutions such as VMC are the concepts of intelligent actuators and central vehicle control viable.
