DEVICE AND METHOD FOR CONTROLLING BRAKING OF A MOTOR VEHICLE

摘要

A method for control of braking by a supplementary brake (290-296) of a motor vehicle (100; 110): Choose (s410) supplementary braking by a control device (270). Continuously determine 20) total available supplementary brake torque (Mtot) and determine (s430) by the control device (270) a chosen proportion (Mshare) of total available supplementary brake torque (Mtot). Determine (s440) a supplementary brake torque (Mtot*) corresponding to the chosen proportion share) and apportion (s450) supplementary brake torque determined (Mtot*) to a chosen supplementary brake (290-296). A computer programme (P) implements the method. A device controls braking by a supplementary brake (290-296). A motor vehicle (100; 110) is equipped with the device.

1. A method for control of braking of a motor vehicle by means of at least one supplementary brake, comprising the steps of:
choosing a supplementary braking action from more than one braking action by a control device; continuously determining a total available supplementary brake torque (Mtot); determining by means of said control device a chosen proportion (Mshare) of said total available supplementary brake torque (Mtot); determining a supplementary brake torque (Mtot*) corresponding to said chosen proportion (Mshare); and using a prevailing vehicle speed as a basis for apportioning said supplementary brake torque determined (Mtot*) to at least one chosen supplementary brake in order to achieve the chosen supplementary braking action.
