摘要:
A module for determining speed set-point values vref for a vehicle's control systems includes an input unit configured for input, e.g. by the vehicle's driver, of a reference speed vset which is the speed desired by the driver for the vehicle. A horizon unit is configured for determining 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 is configured for calculating vref 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. The processor unit is further configured for determining a control signal with control parameters for the vehicle's automatic gear change control unit, based on one or more vehicle-specific values and a calculated speed set-point value vref.

A method for determining speed set-point values vref for a vehicle's control systems including determining a horizon from position data and map data of an itinerary made up of route segments with at least one characteristic for each segment; calculating threshold values for the characteristic of segments according to one or more vehicle-specific values, which threshold values serve as boundaries for assigning segments to various categories; comparing the characteristic of each segment with the calculated threshold values and placing each segment within the horizon in a category calculating set-point values for the vehicle's control systems across the horizon according to rules pertaining to the categories. When any characteristic in segments within the horizon indicates a hindrance, calculating the vehicle's retardation determining a start position within the horizon for commencement of retardation according to its calculated retardation in order to achieve a lowering of the set-point speed vref to a maximum speed required by the hindrance at the location of the hindrance; adapting the speed set-point values vref within the horizon according to the start position and retardation of the vehicle and regulating the vehicle's speed according to the speed set-values vref. Also a module determines set-point values for a control system in the vehicle.
摘要:
A reactive silencer intended for industrial supply air or exhaust air channels has a sound attenuator chamber (10), to which is fitted a partition wall (12) dividing the sound attenuator chamber into a first and second chamber part (14, 16). The partition wall (12) is fitted with two or more channels or pipes (26, 26′, 26″) which connect the first chamber part (14) to the second chamber part (16). In this way a silencer of small size and simple structure is obtained for attenuating noise, especially that produced by large or several small air channels.
