Identification of Road Properties in Advanced Active Safety Applications: Overview and Conceptual Solutions 2005-01-1488
An important problem of recent active safety applications is data acquisition for parameters of tire-road interaction, especially coefficient of friction or specific forces in contact patch. Analysis of present solutions in this field allows setting off the virtual and hardware-based determination of tire grip properties.
The virtual procedures can be subclassified into
Dynamics simulation method
Fuzzy logic method.
The hardware-based procedures are connected with
On-board sensors of direct tire grip measurement
On-board sensors of indirect tire grip measurement
Off-board (on-road) sensors.
For above mentioned variants the appropriate engineering solutions are considered in the paper.
The long-term approach in road identification centers on active safety applications with on-road sensors, which are integrated in intelligent transportation systems (ITS). The paper proposes conceptual structure for this system.
