Abstract | Methods and systems are provided for updating a relevant vehicle parameter in a vehicle so as to improve accuracy of a vehicle velocity determination. In one example, a method comprises integrating signals of a longitudinal acceleration sensor to obtain a first vehicle velocity and obtaining a second vehicle velocity from a wheel speed sensor between a first and a second reference point, and updating the relevant vehicle parameter as a function of a difference between a slope associated with the first vehicle velocity and another slope associated with the second vehicle velocity. In this way, accuracy of vehicle speed determination via one or more wheel speed sensors may be improved. |
