signal. If the signal amplitude increases, the stepper motor with its
maximum speed is not able to follow the required position.
The LIN-bus is able to provide enough samples.
The system mechanics are the limiting factor.
Figure 8-3. Road1 Signal
Figure 8-3 shows a non-sinusoidal signal of required position
positionReq be followed by the actualPosition signal. It can simulate
a HID levelling system on a road.
Therefore, we can say that the LIN Leveller described in this reference
design could be an advanced solution for HID headlamp levelling control
with a very competitive system cost thanks to:
• LIN-bus communication protocol
which is a cost-effective bus system based on standard SCI (UART)
communication and:
