Abstract
A method in a vehicle for estimating vehicle motion state during a vehicle maneuver, comprising; obtaining a trigger signal indicating an onset of the vehicle maneuver, selecting a sub-set of wheels on the vehicle to be in a free-rolling condition, measuring one or more parameters related to revolution of the sub-set of wheels in free-rolling condition, and estimating the vehicle motion state based on the measured parameters.
Claims19
A computer implemented method in a vehicle, the vehicle including a primary system, for estimating vehicle motion state during a vehicle maneuver when the primary system is not available,
- wherein the vehicle motion state comprises vehicle position, the method comprising;
- determining that the primary system is unavailable;
- obtaining a trigger signal indicating an onset of the vehicle maneuver,
- lowering a liftable wheel axle,
- controlling at least one wheel on the liftable wheel axle, to be in a free-rolling condition, wherein the free-rolling condition comprises reduced braking,
- measuring one or more parameters related to revolution of the at least one wheel on the liftable wheel axle in free-rolling or reduced braking condition, and
- estimating the vehicle motion state based on the measured parameters.
