Gear Shifter Simulator

1) Aim - To simulate a gear shifter by giving speed as input.

Objective - Make a Simulink chart to simulate a gear shifter as per below conditions:

Speed Range (kmph)	Gear
0 to 15	1
16 to 25	2
26 to 40	3
41 to 60	4
Above 61	5

Final Model :

Simulink Model :

Stateflow Chart :

Procedure :

1. Create a Stateflow chart for the given speed and gear correlation, such that speed (kmph) is the input and gear is the output value.
2. Connect a slider gain to chart's input, ranging from 0 to 100 along with a constant.
3. Connect a Gauge and a Display for displaying the speed data.
4. Connect a Vertical Gauge and a Display for the gear data.

Explanation :

• The simulation time is set to 'inf' (infinity).
• After starting the simulation, the slider gain is used to give the input (speed).
• This speed data is displayed by a Display and a Gauge.
• This input goes to the Stateflow chart which gives the output in form of gear's numerical value according to its logic.
• This output data is displayed by a Display and a Vertical Gauge.
• The simulation is manually stopped when desired.

Input (Speed) :

Here is the speed input from the slider as observed from a scope:

Output (Gear) :

Here is the output (gear) as observed from a scope:

Result :

Gear 1: (Speed 1 to 15)

Gear 2: (Speed 16 to 25)

Gear 3: (Speed 26 to 40)

Gear 4: (Speed 41 to 60)

Gear 5: (Speed above 71)

Overspeeding : (Speed above 90)

Conclusion :

The simulation of gear shifter for the given correlational data between speed and gear is completed.
