Context aware adaptive feedback in a steer-by-wire system

Abstract

A haptic vehicle steering feedback system including a sensor for detecting a plurality of objects proximate to a host vehicle and for generating an object map localized on the host vehicle, a vehicle sensor for detecting a vehicle speed and a vehicle lateral acceleration, a rotational torque sensor for detecting a driver applied torque to a steering wheel, an ADAS system for estimating a driver performance in response to the vehicle speed, the vehicle lateral acceleration and the driver applied torque, and for determining an ADAS torque weight factor in response to the object map, an ADAS feature behavior, and the driver performance, a feedback motor for applying a weighted feedback torque to the steering wheel in response to the driver applied torque and the ADAS torque weight factor.
