FIELD: transport.SUBSTANCE: invention relates to definition of vehicle preset speeds. Proposed method includes the steps whereat horizon is defined with the help of positioning data and route map data, threshold magnitudes for road section description are calculated in compliance with one or more magnitudes, comparison of the gradient of every section and computation of preset speeds for automotive control systems using the data on horizon are executed. Additionally, deviations are added to designed preset speeds to adjust the vehicle speed in compliance with preset speed values. Proposed module comprises horizon unit and processor unit. Processor unit computes threshold values for gradient of sections in compliance with one or more magnitudes to compute preset speed magnitudes. Additionally, this unit can add deviations to designed preset speeds when vehicle is located at steep ascent or descent.EFFECT: fuel savings.16 cl, 6 dwg |
