4 wheel drive (4WD) with one electric motor per wheel is often used for electric sport cars. Very competitive and high power solutions can be achieved.
We simulated sport car 4WD wheel drive acceleration on dry asphalt and ice, plus braking and cornering on same surfaces. Different levels of wheel torque can be applied and different steering angles. This kind of simulation is a basic step towards torque vectoring regulation.
For accelerating and braking linear velocity, pitch angle and wheel velocities are shown.
For cornering front wheels steering angle, longitudinal velocity, lateral velocity, yaw rate, rotational velocity of each wheel, sideslip angles, roll angle, normal force of each wheel acting on the surface and cars trajectory in x-y coordinate frame are shown
