Wheel Group
Steering
Steer Coefficient
determines how much the wheel will steer depending on input. In general cars would haveSteer Coefficient
of 1 in front and 0 in the back, except for four wheel steering cars where rear axle usually steers opposite of the front so the value would be negative. Examples:1
- 100% steering.0
- no steering.-0.5
- 50% steering in the opposite direction.
Add Ackerman
- check this Wikipedia link for more info about Ackerman Steering setup.- Set automatically for 4-wheel (2×2) vehicles. Not used for motorcycles.
- When setting it manually, set to <0 for Reverse or Anti Ackermann or >0 for Ackermann steering. Field represents percent where 0.12 equals 12% of the steer angle. Following image describes the effect:
Brakes
Brake Coefficient
- amount of brake torque used as a percentage ofBrakes
⇒Max Torque
.Handbrake Coefficient
- amount of brake torque applied when handbrake is activated.
Geometry
Toe Angle
- toe angle in degrees.
Caster Angle
- caster angle in degrees.
- Note: Camber is no longer set through the WheelGroups, except in case of
isSolid
being true, as in that case the camber is calculated so that the wheels always stay parallel to each other.- For fixed camber the camber is set through the WheelController. For dynamic adjustment of camber, the CamberController component can be attached to the WheelController.
Axle
Axle settings are used only if there are exactly two wheels in the WheelGroup
.
Anti Roll Bar Force
- deprecated,Force Application Point Distance
onWheelController
should be used instead. Higher the value, lower the roll.Is Solid
- Imitates solid axle and auto-adjusts camber to make sure that both wheels always stay parallel to each other.
