Lap Trigger

Lap trigger (timing beacon)

Why do we need a lap trigger (timing beacon)?

▪ Vehicle lap time measurement
▪ Calculation of lap‐dependent functions (lap fuel consumption, min/max val‐

ues)

▪ Calculation of lap distance dependent functions
▪ Control of data logging system

System consists of

▪ Transmitter (trackside unit)
▪ Receiver (in‐vehicle unit)

Lap Trigger
Receiver

Lap Trigger
Transmitter

Types of systems

▪ GPS based (low cost, low precision)
▪ IR based (low cost, high precision, limited reliability)
▪ RF (microwave) based (high precision, high reliability)

Electrical trigger signal

In DDU 7 all sources of measurement channels can be used as trigger signal.

▪ Analog input
▪ Digital input
▪ CAN input

Signal (measurement channel) properties

Low active signal (Bosch triggers): Trigger releases if signal is below the thresh‐
old.
