Title: Innovations of Nicholas John Kalweit
Introduction
Nicholas John Kalweit is a prominent inventor based in Novi, MI (US), known for his significant contributions to the field of hybrid electric vehicle technology. With a total of 14 patents to his name, Kalweit has been instrumental in advancing the efficiency and performance of hybrid powertrains.
Latest Patents
One of his latest patents focuses on hybrid electric powertrain architectures and control logic for vehicle response management. This innovation presents methods for making and operating hybrid electric vehicle (HEV) powertrains, as well as motor vehicles equipped with these powertrains. The method involves controlling a hybrid powertrain by receiving data indicative of motor speed and torque commands for the motor, engine, and engine disconnect clutch (EDC). The vehicle controller utilizes a state observer module to estimate a jerk response based on motor speed and determines the active state of the EDC. If the EDC is active, the controller calculates an incremental feedback control signal to reduce the estimated jerk, modulating torque output accordingly.
Another notable patent involves systems and methods for determining indicated mean effective pressure (IMEP). This engine control system includes a cylinder control module that activates and deactivates engine cylinders based on torque requests. It also features a values module that determines coefficients and an offset value based on the target sequence, allowing for accurate IMEP determination of the engine's cylinders.
