Abstract: A method for evaluating a status of a vehicle, the method may include (i) obtaining sensed information during one or more driving sessions of the vehicle; (ii) determining, based on the sensed information, (a) multi-component-model (MCM) behavioral information regarding one or more MCM driving events, and (b) a component behavioral information regarding one or more component driving events; wherein a behavior of at least one first part of the vehicle during the one or more MCM driving events is indicative of a status of one or more MCMs; wherein a behavior of at least one second part of the vehicle during the one or more component driving event is indicative of a status of one or more components; (iii) determining the status of the one or more MCMs, based at least on the MCM behavioral information; and (iv) determining the status of the one or more components, based at least on the component behavioral information, the status of the component.

Abstract: A method for estimating an effective radius of a tire of a vehicle, the method may include (i) obtaining sensed information that reflects (a) a distance passed by the vehicle during one or more driving sessions, (b) a rotational speed of at least a wheel that comprises the tire during the one or more driving sessions, (c) values of tire radius affecting parameters during the one or more driving sessions, wherein the tire radius affecting parameters comprise a vehicle speed and at least some other tire radius affecting parameters; (ii) selecting at least one portion of the one or more driving sessions; and (iii) determining the effective radius of the tire of the vehicle based on (a) sensed information gained during the at least one portion, the sensed information comprises values of the tire radius affecting parameters during the at least one portion, and (b) one or more relationships between the effective radius of the tire and tire radius affecting parameters.
