Q1. For CVT model the following blocks are used as follow

1) Signal Builder

2) Generic Engine

3) Signal Builder For CVT signal

4) Engine Sensor

5) Simple Gear

6) Vehicle Body

Explanation:-

For thr run this model we have to you all different type of component and parameter to get an desire output.

We use signal builder for entire model the signal in the form of break input and throttle input.

we are giving the input as throttlr there 0.5 upto 20sec and 1 after 20 sec. Also we add the different data to this signal builder as per our requirment

When we increasing the throttle the velocity is increasing and after certsin time it reach the maximum velocity

Then the output from signal builder we connect to the input of the generic engine.But the signal builder are not directly connected to generic engine because signal builder is simulink libeary and generic engine is from simscape so with the help of simulink to ps converter we are conncet those block and feed the data to the engine.

Then engine sensor it is a subsystem of an rpm sensor,inside that subsystem we are use the rpm sensor which is connect to the port value and scope for generating result.

Generic engine output connect to the input of the engine sensor and output of the engine sensor connect to the CVT model

CVT system is the main system that is continous variable trasmission, So it consist of Primery pully,Variator,Secondary pully and Belt.

The variator is connect to the primery pully when it is go outword the variator of secondary pully move inward such that the redius of the secondary pully more than redius of primery pully and it is lead to Rp<Rs that is SPEED REDUCTION.

On the other hand when the variator of primery pully move inward and variator of secondary pully move outward and it is lead to OVER DRIVE Rp>Rs

CVT is an subsystem inside that there is variable gear ratio and input shaft inertia and output shaft inertia which is represented the primery and secondary pully, And then we have to specify the gear ratio. We have variable gear ratio block. and below that there are only two sensor there is no physical meaning for that they are giving only rpm of primery and secondary pully.

Then we have to implement a speed reduction for that purpose we are using simple gear ratio.

Then further we have vehicle body it is also subsystem,inside that there is vehicle body block in that you can specify your number of wheels per axle and many other. With the help of data inspector we can vizsualize raph for that we have to log the signal.
