Electro-Hydraulic Limited Slip Differential

This example uses:

Open Model

This example shows a simple way of modeling an electro-hydraulic limited slip differential system. The model shows the velocity and the torque profile responses achieved for the left and the right wheels.

Model

The following figure shows the model of an electro-hydraulic limited slip differential system with a test harness. The electronic control unit sends a command to the pressure control solenoid valve based on the relative slip between the right and the left wheels. The pressure control solenoid valve applies a pressure on the actuating mechanism which in turn applies the limited slip control.
