An apparatus and method, for estimating confidence in a vehicle reference velocity, comprises a controller having an electronic processor 21 for receiving at least one first vehicle operating parameter, such as vehicle acceleration. The electronic processor 21 is configured to access a memory device 23 and execute instructions stored therein such that it is operable to monitor the at least one first vehicle operating parameter; and to calculate a confidence value representing the confidence in the vehicle reference velocity, the confidence value being calculated in dependence on the vehicle operating parameter. The reference velocity is calculated from the wheel speed signals WS1-4, either by the processor 21 or a separate processor. A sensor 15 is provided to output a throttle pedal position signal S1. A pressure sensor 17 is provided to output a brake pressure signal S2. A steering wheel angle sensor 19 is provided to output a steering angle signal S3.

A method of determining vehicle entry information for a user includes obtaining a yaw measurement using a mobile device, determining, using a processor, a first time span associated with a user entering a vehicle, and determining, using the processor, a second time span associated with a user exiting the vehicle. The method also includes determining that a change in magnitude over a portion of the yaw measurement is greater than a predetermined threshold over at least one of the first time span or the second time span and determining an angular change of the yaw measurement over the predetermined threshold. The method further includes associating right hand entry with the vehicle entry information if the angular orientation of the yaw measurement is clockwise and associating left hand entry with the vehicle entry information if the angular orientation of the yaw measurement is counter-clockwise.

A safety arrangement for a vehicle, the arrangement comprising: a control unit; one or more vehicle sensors, the sensors being connected to the control unit so the control unit receives output signals from the sensors; a road detection arrangement to detect a surface or an edge of a road in the vicinity of the vehicle and determine whether the vehicle has left the road and is being driven over a surrounding non-road surface, or is likely to do so; and one or more vehicle safety systems which may be activated by the control unit, wherein: the control unit is configured to process the signals received from the sensors and to determine whether the vehicle is travelling over rough terrain, or is entering a ditch-like feature, or the vehicle is airborne; the control unit is configured to activate the one or more vehicle safety systems if it is determined from the signals received from the sensors that the vehicle is travelling over rough terrain, or is entering a ditch-like feature, or the vehicle is airborne; and signals from the sensors, or one or more quantities derived or calculated from signals from the sensors, are compared against at least one threshold to determine whether to activate the one or more vehicle safety systems, wherein the threshold is set at a first level if it is determined by the road detection arrangement that the vehicle has not left the road, and is not likely to do so, and at a second level if it is determined that the vehicle has left the road, or is likely to do so.

Arithmetic circuitry (20) of a roll angle estimation device 10 estimates a roll angle of a moving body (1; 100), and estimates a pitch angle and a pitch angular velocity of the moving body (1; 100) and at least one offset error of the first and second angular velocity detectors (51, 52) and the first, second, and third acceleration detectors (53, 54, 55). In a current estimation operation, the arithmetic circuitry (20) estimates the roll angle, pitch angle, and pitch angular velocity of the moving body (1; 100) and the at least one offset error, based on: detection values by the first and second angular velocity detectors (51, 52); detection values by the first, second, and third acceleration detectors (53, 54, 55); a detection value by the velocity detector (7; 6); estimated values of the roll angle, pitch angle, and pitch angular velocity from a previous estimation operation; and an estimated value of the offset error from the previous estimation operation.
