CSE Components

States Array

There are two states in the CSE:

Element	Description	Units
1	Engine Speed	[rad/sec]
2	Clutch Slip	[rad]

Initial Condition Array

Element	Description	Units
1	Engine Speed Initial Condition	[rad/sec]
2	Clutch Slip Initial Condition	[rad]

Input Array

Element	Description	Units (of Value)
1	Throttle Demand Variable ID	[No Units]
2	Clutch Demand Variable ID	[No Units]
3	Transmission Speed (at gear box input) Variable ID	[rad/sec]
4	Gear Demand Variable ID	[No Units]

Output Array

Element	Description	Units
1	Throttle Position	[0-1]
2	Engine Speed	[rad/sec]
3	Clutch Slip	[rad/sec]
4	Clutch Slip Velocity	[rad/sec2]
5	Engine Torque	[Model Units]
6	Clutch Torque	[Model Units]
7	Throttle Position At Static	[0-1]
