LEVELS OF STEERING CONTROL; SOME NOTES ON THE TIME-TO-LINE CROSSING CONCEPT AS RELATED TO DRIVING STRATEGY

A description is given of a research project on "levels of steering control", in which the distinction between open and closed loop control strategies in driving is discussed. In most driving control models emphasis is put on a closed loop or error control, strategy. Even when an open loop strategy is taken into account, an error control mode is always assumed to function in parallel. The preliminary thoughts laid down in this research note are based on the idea that it may be useful to develop a driving model in which the open and closed loop strategies act serially rather than in parallel. As far as open loop control is concerned, a distinction is made between an active and a passive control mode. In the active mode the driver generates an open loop steering action which may be either of a precognitive or a pursuit nature. In the passive mode the driver may either hold the steering wheel in a fixed position (fixed control) or he may release it (free control). The "time-to-line crossing" concept is discussed as a variable which may be useful for describing the efficiency of open loop control strategies and which may also serve as a tool in modelling driving strategy.(a) for the covering abstract of the conference see TRIS abstract no. 369460.
