METHOD AND DEVICE FOR CONTROLLING THE REFERENCE SPEED OF A DOWN-HILL SPEED CONTROLLER
First Claim
1. A method for governing a reference speed vref—
-
dhsc for a downhill speed control system in a vehicle in connection with vehicle travel on a downhill gradient, which enables an increased reference speed vref—
dhsc—
schwung of the vehicle in a final part of said gradient,the method comprises;
simulating at least one future speed profile vsim for an actual speed for said vehicle on a section of road in front of said vehicle, wherein said simulation is based on topographic information;
establishing whether said reference speed vref—
dhsc is to be allocated said increased reference speed vref—
dhsc—
schwung, wherein said establishing is based on a comparison of said simulated future speed profile vsim with a permitted magnitude for said increased reference speed vref—
dhsc—
schwung and/or with an infringement speed vsl, andallocating said increased reference speed vref—
dhsc—
schwung to said reference speed vref—
dhsc if said establishing has been accomplished.

26. A system for governing a reference speed vref
— -
dhsc for a downhill speed control system in a vehicle, in connection with a downhill gradient, wherein said system is configured and operable to provide an increased reference speed vref
— dhsc— schwung in a final part of said gradient, said system comprising;a simulation unit configured to simulate at least one future speed profile vsim for an actual speed for said vehicle on a section of road in front of said vehicle, where said simulation is based on topographic information; an establishment configured to establish whether said reference speed vref — dhsc is to be allocated said increased reference speed vref— dhsc— schwung, wherein said establishment is configured to compare said simulated future speed profile vsim with a permitted magnitude for said increased reference speed vref— dhsc— schwung and/or with an infringement speed vsl, andan allocation unit configured to allocate said increased reference speed vref — dhsc— schwung to said reference speed vref— dhsc if said reference speed has been established.
