Abstract: A turning-characteristic estimating unit of an ECU estimates a stability factor and a steering-response time constant coefficient that are parameter values related to turning characteristics of a vehicle. A standard yaw rate of the vehicle is calculated using the estimation values of the stability factor and the steering-response time constant coefficient estimated by the turning-characteristic estimating unit. A validity determining unit of the ECU determines the validity of the estimation values based on the standard yaw rate and an actual yaw rate of the vehicle. This allows improving the estimation accuracy of the stability factor and the steering-response time constant coefficient.

Abstract: The present application provides a system, method and non-transitory computer readable medium for mounting angle estimation and compensation for in-vehicle devices with an accelerometer sensor. In example embodiments, a two phased calibration starts with the vehicle parked on a horizontal surface and uses averaging to obtain mean value estimates of the force due to gravity on each directly coupled accelerometer sensor axis. These mean value estimates are used to perform an axes reassignment, if necessary, and to estimate the pitch and roll mounting angles. The calibration is completed by estimating the yaw mounting angle while the vehicle is driven. The yaw estimate is based on acceleration data in the vehicle's x-y plane that is accumulated when the amplitude is above a threshold. The accumulation includes a sign change if forward deceleration is indicated.

Further, a method of diagnostics of eccentricity of a rotating rotor is based on this method for determining current eccentricity.

Abstract: In a wheel position detecting device, a receiver acquires gear information indicating a tooth position of a gear rotating in association with a corresponding wheel at a predetermined interval. In a wheel position detection, the receiver sets a variation allowance range based on the tooth position at a reception timing of a frame transmitted from a transmitter integrated to each wheel. When the tooth position of the gear at a subsequent reception timing of the frame is not within the variation allowance range, the receiver excludes the wheel corresponding to the gear from a candidate wheel. The receiver registers the wheel remaining last as the wheel to which the transmitter is integrated. The receiver performs the wheel position detection only when a wheel speed is higher than a predetermined threshold, so that the wheel position detection is performed based on an accurate tooth position.
