The vehicle of the future is very likely to be electric. Electric vehicles with multiple motors allow torque-vectoring, which can be used to generate a direct yaw moment by assigning different motor torques at the left and right wheels. This permits to design the steady-state cornering response of the vehicle according to either vehicle dynamics targets, e.g. handling, or energy efficiency criteria. Advanced vehicle dynamics controllers often need the availability of the tire-road friction coefficient and/or the vehicle sideslip angle, which is challenging/expensive hence unfeasible on commercial passenger cars. This motivates estimation techniques based, e.g., on Kalman Filters. The seminar will present: i) experimental results of two EU Projects showing how torque vectoring can enhance vehicle safety, driveability, and energy efficiency; ii) a brief overview of estimating techniques and a recently developed method to estimate vehicle sideslip angle.
