This research project in cooperation with IAV in Gifhorn aims to improve the kinematic state estimation for battery electric vehicles in the low speed range. For this purpose, estimation methods are to be developed, with which the velocity of the vehicle's center of gravity can be determined from the rotational speed of the electric motor, even at low speeds. Parameter variations and aging effects of the vehicle components as well as varying environmental conditions will be taken into account in order to ensure a reliable estimation of the state over the entire service life of the vehicle, regardless of the area of application. In addition, it is important that the estimation method can be easily transferred between different battery-electric drive concepts in order to keep the application effort for parameterization and approval processes as low as possible.
