CTE - OVERSTEER 2.4 DRIFTING: The Physics Behind the Most Accurate Drift Simulation



According to European accident statistics 2/3 of the accidents with serious outcome could have been avoidable by the usage of driver assistance systems. A considerable part of these accidents are pile-up accidents, from which more than half can be traced back to lack of attention. Beyond the pile-up, accidents where commercial vehicles are involved are typically caused by drifting out, jack-knifing or rolling over.




CTE - OVERSTEER 2.4 DRIFTING



Conventionally, the control systems of vehicle functions to be controlled are designed separately by the equipment manufacturers and component suppliers. One of the problems of independent design is that the performance demands, which are met by independent controllers, are often in interaction or even conflict with each other in terms of the full vehicle. As an example braking during a vehicle manoeuvre modifies the yaw and lateral dynamics, which requires steering action or, as another example, under/oversteering requires braking intervention. The second problem is that both hardware and software will become more complex due to the dramatically increased number of sensors and signal cables and these solutions can lead to unnecessary hardware redundancy.


The RUDDER control provides the operator with the means toincrease ordecrease the angle of rudder applied in relation tocourse error and shouldbe adjusted to provide positive correctionof Yaw without oversteer (Section2.19 refers). 2ff7e9595c
