Implementation and integration of slip and traction controllers for a three-wheel electric vehicle
(2022)Department of Automatic Control
- Abstract
- The purpose of the Master Thesis is, on one hand, to develop a traction control system, integrating and implementing two controllers in the vehicle, each of them previously designed and tested separately, to test them together to evaluate their performance. On the other hand, to develop accurate and well-performing controllers, the data acquisition needs to be precise so parameters and devices need to be tuned again, because of small modification in the structure of the vehicle. Parameters such as the cornering and longitudinal stiffness were studied to have more faithful simulations, and devices such as the gyroscope and the ABS were tuned. Moreover, along the lines of acquiring accurate data, another purpose of the Master Thesis is to... (More)

Parameters such as the cornering and longitudinal stiffness were studied to have more faithful simulations, and devices such as the gyroscope and the ABS were tuned. Moreover, along the lines of acquiring accurate data, another purpose of the Master Thesis is to develop procedures or algorithms to acquire data using automated approaches, instead of the manual approaches that were used previously, specifically concerning the wheel’s angles.
A mathematical representation of the vehicle dynamics, developed by Nilsson and Sandstedt, 2021, is used to simulate the performance of the controllers and to tune them accordingly. Simulations were carried out to test the integration of the controllers and evaluate their performance. The controllers behaved according to the expectations and performed accurate simulations. The controllers should then be implemented in the real vehicle to confirm that their performance is the desired.
The data acquired provided information of each of the studied parameters and they showed that the procedure developed to obtain the wheel’s angles was properly implemented. The devices that needed tuning were properly tuned. The model parameters were updated with new values so that the model represented the real system as well as possible. (Less)
