Hi, im new to the forum. I came across it and im not sure if this is the appropriate place to get help on this but ill go for it im designing an adaptive cruise control system.
There are 3 states in the system.

Off-system is disabled and inactive

Standby-system is enable and inactive, waiting for driver to activate ACC

On-system is active

There are 2 factors in the ON state. Time gap and speed control. In time gap, the speed of the vehicle will be determined based on a gap between a vehicle and the one in front of it. The speed control works the same as any cars speed control.

The states are

S0-off

S1-standby

S2-speed control

S3-time gap

Standby and active are considered to be enabled which is logic high and disable is logic low.
this the general state machine i came up with showing the states. I need help determining the input ouputs for the state transition. I have to get this done by tonight hopefully. Thanks!
