Ralph Richter 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).

  • Patent number: 10260622
    Abstract: A transmission arrangement for a motor vehicle comprises a control device, a machine power electronics system, and an electric machine. The electric machine includes a plurality of windings which are connected to the machine power electronics system via particular phase conductors. The machine power electronics system is connected to the control device. The control device includes a temperature detection portion which is connected to at least one phase conductor and is designed for feeding an excitation signal into the phase conductor. The temperature detection portion is designed for capturing a response signal in the phase conductor, and from the response signal, deriving a winding temperature of the winding assigned to the phase conductor.

  • Patent number: 8297249
    Abstract: The invention relates to a method for controlling the start-up phase of a motor vehicle driven by an internal combustion engine (12). The internal combustion engine (12) is started by an electrical machine (16) that can be operated as a motor, and there is a preferably automatically actuatable clutch (50) in the drive train (11) between the internal combustion engine (12) and the electrical machine (16). A faster start-up response can be achieved if the internal combustion engine (12) is driven by the electrical machine (16) when the clutch (50) is engaged during start-up, and if the clutch capacitance (MK) is reduced according to a defined parameter, preferably the engine speed, the time or the torque (ME) of the electrical machine (16) or similar.

  • Patent number: 8055402
    Abstract: A method for detecting a fault state in an automated motor vehicle gearbox having two parallel branches. Each branch has a clutch and is configured to transmit driving torques from a drive unit to at least one driven wheel of the motor vehicle. The method comprises the steps of sensing whether both clutches are at least partially closed; of sensing the rotational speed of the at least one driven wheel and sensing the rotational speed of a non-driven wheel, and of detection of a fault state if both clutches are at least partially closed, and a difference between the rotational speeds of the wheels is greater than a predetermined reference value.

  • Patent number: 8037858
    Abstract: A method for controlling the start-up phase of a motor vehicle driven by an internal combustion engine (12) wherein the internal combustion engines (12) is started by an electrical machine (16) that can be operated as a motor, a preferably automatically atuatable clutch (50) being located in the drive train (11) between the internal combustion engine (12) and the electrical machine (16). A faster start-up response can be achieved if the internal combustion engine (12) is driven by the electrical machine (16) when the clutch (50) is engaged during start-up, and if the clutch capacitance (MK) is reduced according to a defined parameter, preferably the engine speed, the time or the torque (ME) of the electrical machine (16) or similar.
