BHAITECH VEHICLE STATE ESTIMATOR FOR ADAS

High Performance Chassis Control

 

Existing systems assisting the driver with vehicle stability and aiming to the improvement of its active safety generally rely on some sort of arbitrarily complex vehicle model to evaluate the real-time maneuverability limits of the vehicle. The vehicle dynamics model is commonly referred to as a “vehicle state estimator”.

The accuracy of traditional vehicle state estimators is somehow limited by the employment of fixed assumptions about vehicle operating conditions.

Assumptions are of course biased to the conservative side. Vehicle state estimator performance is then limited when such assumptions lead to underestimate the actual maneuverability limits of the vehicle.

In case of emergency, underestimating vehicle maneuverability limits can have a large impact on the final outcome.

BhaiTech has heavily invested resources in R&D in order to take existing vehicle state estimators to the next generation of embedded vehicle models based on the real-time identification of vehicle operating conditions and maneuverability limits.

BhaiTech can provide its next generation of vehicle models for embedded application. In particular, BHAITECH STATE ESTIMATOR is based on company proprietary intelligent tire technology.

Quantities such as tire loads, vehicle body heave, pitch and roll, static and dynamic CG position are estimated at an unprecedented level of accuracy thanks to the real-time identification of tire mechanical properties e.g. tire spring rate, vertical damping etc.
