BIT Technology recognizes the tyre forces and delivers real time information about tyre-road interaction and the changing conditions, from the reaction to the type of asphalt to the grip and skid margins.
In the human driven vehicle, objective information about vehicle maneuverability in current operating conditions is made available.
The driver is thus assisted in reacting swiftly and safely to the road changing conditions.
In particular, the driver is alerted when the drop in the road-tire friction coefficient exceeds a predefined threshold. As an example, the system can assist the driver in dealing smoothly with the road dry to wet transition.
Among a number of quantities, limit road-tyre friction coefficients are calculated and seamlessly conveyed to car’s active safety systems in order to guarantee vehicle safe operation in relation to the actual conditions.
BhaiTech is looking into possible options to use the information about real-time road‐tyre friction as the primary control variable for a system which shifts the vehicle toward an overall lower friction operating region, whenever this is permitted by the vehicle safety margins and maneuvering resources necessary in that moment.
BIT technology has been developed to be executed using available vehicle hardware. Tyre information and surface friction measurements are derived from existing vehicle sensors, using BIT algorithms running on microcontrollers already on the vehicle.
