Driver 's steering wheel activity detecting method for use in motor vehicle, involves deriving whether driver of motor vehicle moves steering wheel or not from logic function of Boolean variables

摘要

The method involves determining and differentiating regulating moment (RM) exerted on a steering element by a driver assistance system in a block (5). A regulating moment speed (RMV) is resulted from the amount of the differentiated moment. A steering moment changing limit (LMG) is derived from the regulating moment speed. A steering moment speed (LMV) is compared with the changing limit for determining a value of one of two Boolean variables (B1). A derivation is made to find whether a driver moves a steering wheel or not from a logic function (11) of Boolean variables (B1, B2). An independent claim is also included for a device for implementing a method for detecting steering wheel activity of a driver in a motor vehicle.
