Disclosed is a method for registering items of equipment () for a vehicle. In each case an ID code is assigned to the items of equipment () and wherein the items of equipment () comprise in each case at least one transmission means (). The ID codes are transmitted by the transmission means () concerned to the recording means () and registered by the recording means ().

A safety device for detecting manipulations on a bus system of a vehicle includes a receiver configured to connect to the bus system of the vehicle and to receive a signal from the bus system, an analyzer configured to analyze a transition between signal states of the signal, and an evaluator configured to evaluate the signal as a manipulated signal or an unmanipulated signal based on analysis performed by the analyzer.

A navigational system and method for guiding a boat onto a trailer, which comprises at least one marker mounted on the trailer; a camera located on the boat to assist the system with determining a longitudinal axis of the boat, and generating images of at least a front area of the boat and the at least one marker; an image processing unit for 1) receiving and processing the images to determine the at least one marker, 2) estimating the longitudinal axis of the trailer, 3) generating a desired boat trajectory for aligning the longitudinal axis of the boat with the longitudinal axis of the trailer; and 4) periodically generating guidance output commands to the user to assist the user with following the desired boat trajectory and facilitate loading of the boat on the trailer; and an image display for sequentially displaying the generated images of the camera to a user.

Camera based boat loading assistant

A navigational system for guiding a boat onto a trailer comprising at least a portion of a tow vehicle which forms a natural marker for the navigation system. A camera is located on the boat to assist the navigational system with aligning a longitudinal axis of the boat with a longitudinal axis of the trailer. A central vertical (mid) axis of the camera is aligned with the longitudinal axis of the boat. An image processing unit receives and processes images from the camera. The image processing unit, based upon a determination of a position of the central vertical (mid) axis of the camera relative to a target area of the detected natural marker, generating guidance commands to assist a user with alignment of the longitudinal axis of the boat with the longitudinal axis of the trailer and thereby facilitate proper loading of the boat onto the trailer.

A process for determining a setpoint rotational speed of a work machine engine, having a continuously variable transmission, based on operation of power hydraulics. The setpoint rotational speed for highly productive operation is determined, without knowledge current operation of the power hydraulics, by a basic engine speed setting. With knowledge of the current operating state, the setpoint rotational speed is determined by the basic speed settings and low or high engine speed settings. The low speed setting alone determines setpoint rotational speeds that are lower than the basic speed setting or a combination of the low and basic speed settings. The high speed setting alone determines setpoint rotational speeds that are higher than the basic speed setting or a combination of the basic and high speed settings. The speed settings can comprise a setpoint rotational speed range of above a reciprocal transmission range of the variable transmission.

A method of controlling a continuously variable transmission for a vehicle. The continuously variable transmission has a hydrostat with a position-regulating valve and is designed to co-operate in driving connection with a drive input shaft and a drive output shaft such that when the position-regulating valve is energized, the hydrostat is adjusted to accelerate the vehicle. The method includes monitoring the energization of the position-regulating valve cyclically by a safety function. The safety function is provided in order to recognize undesired energization of the position-regulating valve that leads to unwanted acceleration of the vehicle, and then to separate the transmission at least from the drive output shaft so as to prevent unwanted acceleration of the vehicle. The safety function is triggered at least when a limit value for the energization of the position-regulating valve is exceeded.
