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.

A driving assistance system that executes deceleration assistance of a vehicle when a relative state between the vehicle and a deceleration object ahead satisfies a preset condition includes a brake operation detection unit configured to detect whether a brake operation is performed by a driver of the vehicle during the deceleration assistance, a deceleration gradient setting unit configured to, when a brake operation is performed by the driver during the assistance, set a deceleration gradient to stop the assistance based on at least one of presence or absence of a forward obstacle ahead, a relative state between the vehicle and the forward obstacle, and a road environment in which the vehicle travels, and a deceleration assistance stop unit configured to, when a brake operation is performed by the driver during the assistance, stop the assistance of the vehicle along the deceleration gradient set by the deceleration gradient setting unit.

A braking system and method utilizing a simplified estimate of a distance between two locations on the earth based on spherical geometry. A braking system utilizing the aforementioned simplified estimate does not require computationally intensive calculations and is more efficient and better equipped to handle real-time generation of distance estimates for braking needs and variable conditions. In the present invention, geodesics evaluations are not used; rather, a modified Haversine formula that simplifies computations is used, including a one-time computation of the cosine of latitude coordinate.

A method for determining the values of parameters for a controller of a vehicle, wherein respective error measures are calculated for different sets of values and a set of values is selected based on the error measures.

A tire radius monitoring system for dynamically determining a tire effective radius for each of the wheels on a vehicle is described. The system includes a GPS sensor, a plurality of wheel speed sensors, and a controller. The controller determines, via the GPS sensor, a velocity vector related to longitudinal velocity of the vehicle. The controller determines wheel speeds for the plurality of vehicle wheels, and detects a no-wheel-slip state for the vehicle wheels and the velocity vector from the GPS sensor. The controller determines tire effective radii for the plurality of vehicle wheels based upon the velocity vector for the vehicle and the wheel speeds for the plurality of vehicle wheels during the no-wheel-slip state, and controls vehicle operation based upon the tire effective radii.
