Abstract A method of estimating the wheel speed of a wheel of an in-wheel electric vehicle, the vehicle having an electric 5 motor which produces a back EMF when driving that wheel, the method comprising: obtaining two or more signals which are related to the wheel speed, at least one signal being obtained from the back EMF of the electric motor that drives the wheel; 10 processing the two or more signals to derive an estimate of the wheel speed; and producing an output indicative of the wheel speed from the wheel speed estimate. 5520179_1 (GHMatters) P97310.AU 25/06/14 Left Right Front Front Signal Sigal ABS Transmission Transmission ABS Sensor Motor Driver: I Braking I 15 Command Local Local Controller Controller 12 Communication Network I Local o Controller t > Controller 13 Central Brake CoContrllere1 Left embedded in Rigt 10 Re\ ECU Ra ABS SgaSi1ABS Sensor in-Wheel Transmission Transmi ion Sor Motor Motor 14 FigI damper brake motor car wheel wheel simulating relative road motion driving motor . encoder brake Fig. 2 5487714_1 (GHMatters) P97310.AU
