Page 956: Abd System Description
ANTILOCK BRAKE SYSTEM 4F-7 ABD SYSTEM DESCRIPTION General: The Automatic Brake Differential Lock (ABD) is a traction system by means of brake intervention only, available in a low speed range (< 60kph). It workes on m-split roads with sidewise different friction coefficients. The spinning driven wheel is braked and the drive torque can be transferred to the wheel on the high- m side.
Page 957 4F-8 ANTILOCK BRAKE SYSTEM Temperature Model: ABD operation is a high thermal load for the brakes. To avoid any damages at the brakes, the disk temperature is calculated with a mathematical model for each driven wheel separately. After ignition on, the calculation starts with 30° C and then three different phases are evaluated separately and added: ABD operation, braking and coling phase.
