BHAITECH INTELLIGENT TYRE

Real-time identification of operating conditions & vehicle maneuverability limits.

 

Vehicle Maneuvering Limits for Autonomous Driving

 

What are tyre requisites for autonomous driving?

This is probably the most recurrent question tyre people are raising to the autonomous community in order to get clear directions for the development of their tires of the future.

In the absence of a human driver continuously sensing car performance limits, a new source for real-time information about vehicle maneuverability limits will be necessary if autonomous vehicles are to meet satisfactory safety and performance levels.

Fuel Economy & Energy Saving

 

If the instantaneous road-tyre friction level is available then tyre operating conditions can be potentially changed in order to guarantee the necessary maneuvering resources, comfort levels and reduced fuel/energy consumption.

 

MANEUVER

BHAITECH Intelligent Tyre (BIT) is a technology designed to offer an alternative source of real-time information about vehicle maneuverability limits among others.

ESTIMATE

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.

ALERT

In the human driven vehicle, objective information about vehicle maneuverability in current operating conditions is made available.

FEED

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.

SAVE

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.

EXECUTE

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.
