Patents by Inventor Michael Erhart

Michael Erhart has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20130049686
    Abstract: A control circuit for indirectly limiting a load current which flows through a controllable semiconductor component. The control circuit controls the controllable semiconductor component based upon a measured and/or a calculated load-current-dependent power loss of the semiconductor component. The control circuit can also control the controllable semiconductor component based upon a measured and/or a calculated load-current-dependent component temperature of the controllable semiconductor component. A charging circuit includes a controllable semiconductor component for limiting a load current and has a control circuit in accordance with the invention. A motor vehicle includes an on-board electrical power supply system having a charging circuit in accordance with the invention.

  • Patent number: 8170826
    Abstract: The present invention relates to a method for the calibration of a position determination system of a rear axle steering actuator for a motor vehicle. The rear axle steering actuator has an actuator element which can be driven by a rotary movement of a rotor to a translation movement and whose geometrical center position is determined by a reference measurement. The position determination system includes a linear sensor and a rotary sensor. During calibration, a piece of calibration information is generated which includes a piece of zero point information of the linear sensor and a piece of sector information. The measurement range of the rotary sensor is divided into at least two sectors. The sector information identifies that angle at which the angular position of the rotor lies when the actuator element is arranged in its geometrical center position. The calibration information is stored in the linear sensor.
