In this model, instead of giving input manually to the CVT, a feedback is gievn into the CVT because the gear ratio is affected by the vehicle velocity in real time. For that purpose a lookup table is used in the model
Conclusion
We ran a system level simulation for a BAJA All-Terrain vehicle model using CVT with or without Dashboard and Lookup table based on the above-obtained results in the form of engine speed,vehicle speed, and CVT shaft speed helped to determine the vehicle's performance
brake input is 0 throughout and throttle input is 0.5 throughout
brake input is 0 throughout and throttle input is 0.5 throughout
In the below shown curves, it is quite clear that the Primary CVT RPM and Secondary RPM is more as the throttle increased. Also, with the increased in the throttle value, the speed of the vehicle is also incresed, which is quite
obvious.
In this block, a generic engine data is entered. a sensor is used to record the RPM of the output shaft of the engine
In the below model, two shafts have been used. These are the two shafts of the CVT (one for primary and the other for secondary). This is then connected to the Variable gear ratio and two sensors are used to sense the
On the dashboard, two different knobs have been used, they can be used to variate the brake input and throttle. data can be varied ib real time with the help of these knobs, so as to simulate the model in real world.
The data is then processed and then input to the vehicle body.
In this model, Brake input and throttle input are given by the user in the real time by the dashboard. This data is input to the Engine sensor and then to the CVT block. For, gear ratio, data is entered using a signal bulider
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike, or simply a quad is a vehicle travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles
