Bromsstyrning och förfarande för reglering av referenshastigheten hos denna

摘要

A brake control arrangement for a motor vehicle and a method for controlling the reference speed of such a brake control arrangement. The brake control arrangement (20) is adapted to automatically control one or several brakes (10) of the vehicle so as to endeavour to restrict the speed of the vehicle to the reference speed when the vehicle descends a downhill slope. The reference speed is set to a basic value that is adjustable by the driver of the vehicle and is automatically and temporarily increased f rom the basic value to a modified value when it is established that one or several given conditions are fulfilled so as to thereby allow the vehicle to be accelerated under the effect of gravity in a downhill slope to a speed above the speed corresponding to the basic value.
