Control Logic of Prognostic Type for Vehicles

The rapid development of active safety systems for vehicles necessitates improvement in vehicle control logic that takes into account delay time of mechanical systems, signal processing time by the controller, various options for obtaining quantitative data on the output parameters within a wide range of values with the ability to predict characteristics of the implemented program cycle. Currently, the most popular optimization method of control logic is improving the accuracy of the intellectual assessment of the situation, i.e. increasing the number of sensors that can monitor the vehicle’s position with regards to the basic parameters. However, this method is associated with accumulation of errors and inaccuracies due to the imperfection of control elements and control actions of the driver. To ensure compliance of control logic with the actions of mechanical systems in real time, a prognostic model of control logic is proposed. This model allows synchronization of the quantitative indicators of the output data and the information returned to the control element in real time, thus reducing the discrepancy between the start time of information processing and the time of performing the required actions by the control element.
