Two-wheel vehicles are becoming continuously more important in Europe, but their spread is accompanied by an increase in security concerns due a number of reasons. These include stability problems during braking, and in particular curve braking, which is much more critical than in 4-wheel vehicles. These stability problems are strongly influenced by the behavior of the driver, in particular by his braking and steering activity. In this work we present a curve-safe ABS control, and analyze the role of the driver by a simulation model. It turns out that the demands on the driver in terms of stability control vary strongly with the braking behavior.

Today’s racing motorcycles can provide engine torques higher than the rear tire can transfer to the road. In motorcycle applications, rear wheel torque control can be critical not only for performance, but also for safety, especially in or out of curves. While most drivers can achieve rather good results in handling this high torque on a straight road, the same is not true during cornering. In this paper we present a strategy for traction control which enforces safety while keeping high acceleration even for large roll angles. The proposed control strategy is tested on a motorcycle simulator and performance could be shown during different demonstrative maneuvers.
