- Abstract
- eLSDs (Electronically controlled Limited Slip Differentials)
are showing a more popular trend in the passenger vehicle
industry. Haldex Traction in Landskrona, mostly famous for
their limited slip couplings for AWD (all wheel driven) vehicles,
has now started to develop a differential coupling for a
FWD (front wheel driven) car.
The control of an eLSD in a FWD car affects the traction
capability as well as the handling behaviour. The traction
and handling capability was before the start of this project
controlled using a slip controller and a yaw controller. The
slip controller measures the driven wheels angular velocity
and compares it to the vehicles velocity and then control the
differential accordingly.

Another way to control the differential could be to control
the angular velocity around the cars vertical axis when driving
in a turn. If the car is over steering more than the driver
wants the differential might be able to help. This control
system would be called “yaw rate control” or abbreviated “yaw
control”. (Less)
