Project

REPORT:

Aim:

1. To Study the BAJA ATV model with dashboard
2. To Study the BAJA ATV model without a dashboard
3. To Study the BAJA ATV model with lookup table with dashboard
4. To Study the BAJA ATV model with a lookup table without a dashboard
5. plot Engine torque vs Speed curve for continuously variable transmission for a vehicle. And also to determine the velocity variations over the time for CVT.

CVT

A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps.

CVT MODEL without dashboard:

In this model dashboard is absent,

Inputs:

Torque and speed inputs are given by MatLab workspace. The throttle signal is generated by the signal builder. Output from the engine is given to CVT through gears with an appropriate gear ratio. CVT will generate the variable transmission it is transmitted to the vehicle axel.

CVT plot

ENGINE BLOCK AND CVT

outputs:

Vehicle velocity

Plot for Velocity, distance, throttle, and brake for a specified time of operation.

primary running speed and secondary running speed for cvt.

Plot Engine Torque vs speed

CVT WITH DASHBOARD:

This model same as before except it has input throttle and break nobs which are operated by user.

it has Engine RPM and velocity indicators.

CVT with a lookup table and without Dashboard:

Lookup table

throttle and brake input.

in this model, input is given by a lookup table.Rmain9ing everything is the same as the first one.

CVT with lockup table and with Dashboard:

This resembles the 2nd model with a lookup table instead of inputs through nobs.
