The next generation of driving assistance systems benefits from aviation by using GNSS and inertial navigation systems (INS) to offer a method of controlling vehicle driving dynamics – especially for single- and dual-track vehicles. These dynamics are controlled by way of brake and engine intervention based on how the vehicle’s motion changes in three-dimensional space relative to the global coordinate system and the effective direction of gravity or the Earth’s gravitational pull. The dynamic stability control (DSC) system combines GNSS and INS to track the vehicle’s position, attitude, and speed vector, as well as the direction of gravitational force. It facilitates orientation of the vehicle by detecting sliding, twisting, tilting, skidding, and external impacts. Position and attitude data can still be collected even when, in extreme situations, the vehicle is no longer in contact with the ground. It is thus still possible to predict the direction of the vehicle’s flight/movement. Since vehicles constantly communicate their current orientation, position, speed vector, and attitude to other linked cars through car2car and car2x infrastructures, DSC also serves as an accident avoidance system.
