Re: Using encoders for traction control help

That's not true daltore:

Many vehicles, and most all of the better traction control systems (especially on higher end sports cars) and ABS systems use wheel speed sensors. In fact, next time you go to get your tires changed ask them if they charge extra for wheels that have speed sensors (I know Sams Club and Discount Tire both do).

Acceleration integration, measuring voltages and currents to the motor controllers, and measuring rate of change of the joystick position are all very valid ways of doing traction control, but the absolute best way of doing it is measuring the wheel position / velocity exactly.
