The present disclosure relates to a driver controlling system for a vehicle comprising a propulsive actuator unit, a propulsive sensor unit, and a control unit. The control unit prompts the propulsive actuator unit to apply a driving parameter in an automated driving mode of the vehicle. The driving parameter is based on a driving preference of a driver. The control unit further modifies the driving parameter of the automated driving mode by a defined rate of deviation for causing a reaction of the driver. The propulsive sensor unit generates driver engagement data based on the reaction of the driver to the modified driving parameter. The rate of deviation may be varied and/or the driving parameter may be incrementally modified from a prior modified driving parameter by the defined rate of deviation, in case of insufficient reaction of the user.

Driver controlling system for a vehicle

A method and system for compensating for vehicle disturbances during vehicle operation, including: an algorithm for obtaining predicted driving condition data from a database, wherein the database includes one or more of geospatial data and remote vehicle data; an algorithm for obtaining real-time vehicle state data from equipment communicatively connected to a vehicle; an algorithm for combining the predicted driving condition data and the real-time vehicle state data to formulate a desired steering torque request necessary to compensate for predicted and actual driving conditions experienced by the vehicle; and an algorithm for providing the desired steering torque request to a power steering assist system of the vehicle to compensate for the predicted and actual driving conditions experienced by the vehicle.

Predictive and real-time vehicle disturbance compensation methods and systems

Disclosed is a method of providing a scenario-based overlay torque request signal in a steer torque manager () during driver-override of an auxiliary steering assistance system () function in a road vehicle () having an EPAS system (). The steer torque manager () has a wheel angle controller () for providing an assistance torque request related signal, and a driver-in-the-loop functionality () for determining driver-override and providing a driver-override related signal. The method comprises receiving signals related to: assistance torque request; driver-override; road vehicle velocity; steering pinion angle; distance to an adjacent lane marker (); and distance to an adjacent potential threat object (), and producing, from the received signals, during ongoing driver-override, a signal representative of a resistance torque request corresponding to one of a finite number of pre-defined scenarios for different signal combinations, and producing the scenario-based steering wheel overlay torque request signal through combining the assistance torque request and the resistance torque request signals.
