Abstract: The invention relates to a method for regulating the throwing behavior of a centrifugal spreader for fertilizer and to a centrifugal spreader configured therefor. According thereto, a target throwing distance is determined for a target working width. Furthermore, one of several rotational speed levels is selected for at least one spreading disc to approximate the actual throwing distance to the target throwing distance. Finally, an adapted target throwing angle for regulating an actual throwing angle is determined from the actual throwing distance (WW1) and counteracts in a compensatory manner a deviation from the target working width caused be the difference between the actual throwing distance and the target throwing distance. Continuous regulation of the throwing distance then becomes unnecessary, resulting in more stable regulation of the overall throwing behavior.

Abstract: Disclosed is a vehicle skid recovery system, which is able to accelerate skid recovery, when an automotive vehicle begins to skid as a result of ice accumulation on the road surface. The embodiments control operation of ice removers (e.g., blades or heaters), which are mounted within the wheel wells forward of the wheel, based on information received from the vehicle's outside temperature sensor and anti-lock braking system (ABS). When the temperature sensor indicates that the outside temperature is below a predetermined temperature (e.g., below freezing) and when the anti-lock braking system is activated as a result of detected skid, a controller activates the ice remover in one or more of the wheel wells and, thereby cause the ice remover to remove ice from the road surface forward of the corresponding wheel. Clearing the ice allows the vehicle's tires to gain traction on the road surface and, thereby stops the skid.
