Checklist Wheel Speed Setup

This guide shows the recommend method to configure the individual Wheel Speed measurements. Clicking each item (M1 Tune v1.5 only) will select the item and allow you to enter the required information. Once an item has been selected the help, for that item, can be displayed by hitting the F1 key.

The following procedure is for Wheel Speed Front Left. However the same procedure can be used for Wheel Speed Front Right, Wheel Speed Rear Left and Wheel Speed Rear Right.
 

Configuration

For all the speed measurements to operate the following requirements must be met:

• Wheel Speed Front Circumference must be non-zero.
• Wheel Speed Front Pitch Threshold must be non-zero.
• Wheel Speed Front Timeout must be non-zero.

The sensor measurements can be configured by calibrating the following items. Some of them may not be exposed if they are already defined in this project.

• Set Wheel Speed Front Left Sensor Resource to an available UDIG input.
• Set Wheel Speed Front Left Sensor Pin Pullup Control to On for switch to ground operation.
• Set Wheel Speed Front Left Sensor Pin Active Edge, Wheel Speed Front Left Sensor Pin Threshold, Wheel Speed Front Left Sensor Pin Hysteresis and Wheel Speed Front Left Sensor Pin Debounce according to the sensor type (hall or magnetic). Often it is helpful to measure the sensor signal for the whole speed range to determine suitable values.
• Set Wheel Speed Front Left Sensor Scale if necessary. Otherwise leave at 1.0
• Define the trigger wheel property in Wheel Speed Front Left Sensor Teeth.
