Wheel Speed Signal Splitter
The ABS M4 from Bosch Motorsport relies on specifically‐designed wheel speed
signals, delivered exclusively from active speed sensors, e.g. from the Bosch DF11
family. These sensors are used in current ABS and ESP® systems. The four speed
sensors included in the ABS M4 Kit meet this classification. The signal of a regular
speed sensor, as found in older series production ABS applications, is not com‐
patible withv; they could not be used as signal providers. It is an “open collector”
signal which grounds the voltage at the ECU input with every flank. Bosch Motor‐
sport has developed a wheel speed signal splitter that converts the sensor sig‐
nals in such a way that they can be processed by peripheral ECUs and data re‐
cording systems. This signal splitter is available e.g. for measuring vehicle speed
or traction control. The signals of the different wheel speed signal splitters:
