Module for determining of reference values for a vehicle control system
First Claim
1. A module for determination of speed set-point values for a control system of a vehicle, the module comprising:
- a reference speed input unit configured and operable to input a reference speed, which is the speed obtained for a driver of the vehicle;
a position and map data input unit configured to receive position data and map data for the vehicle;
a horizon and route segment determination unit configured and operable to determine a horizon according to the received position data and map data, and to determine an itinerary made up of route segments with at least one road topography characteristic for each route segment;
a route segment category assigning and speed calculation unit configured and operable to assign, according to the at least one road topography characteristic, each route segment to a route segment category of a plurality of route segment categories,to calculate automatically an introductory speed for each route segment, andto generate, by adjusting each introductory speed according to rules of the route segment category, the speed set-point values across the horizon such that the speed set-point values are within a range bounded by vmin and vmax, where vmin≦
vset≦
vmax; and
the control system is configured and operable to regulate the vehicle according to the speed set-point values.

Abstract
A module for determination of speed set-point values vref for a vehicle'"'"'s control systems, comprising an input unit adapted to input, e.g., by the vehicle'"'"'s driver, of a reference speed vset which is the speed desired by the driver for the vehicle. The module includes a horizon unit to determine a horizon by means of received position data and map data of an itinerary made up of route segments with at least one characteristic for each segment; a processor unit to calculate vref for the vehicle'"'"'s control systems across the horizon according to rules pertaining to categories in which segments within the horizon are placed, so that vref is within a range bounded by vmin and vmax, where vmin≦vset≦Vmax, which control system regulates the vehicle according to these set-point values.
