Efficient antilock braking systems in regenerative brakes

This thesis explores the feasibility of the development of efficient antilock braking systems (ABSs) for In-Wheel Electric Vehicles (EVs). The main idea is to design a sensorless ABS that eliminates the need to install separate conventional ABS sensors. The design significantly reduces the vehicle's manufacturing and maintenance cost and improves the performance of the ABS by accurate wheel speed estimation and road identification, using wavelet signal processing. An alternative proposal in this thesis is a Sensor-fusion-based ABS that improves accuracy, reliability and robustness of the ABS. The proposed systems were developed and extensively tested for brushed and brushless In-Wheel EVs.
