Latest Patents
One of his latest patents is titled "Multi-pulse enable determination and transition control systems and methods." This invention features a coordinated torque control (CTC) system that includes an engine capacity module, a multi-pulse enable module, and a catalyst light-off torque reserve module. The engine capacity module determines the torque capacity of an engine and generates a maximum engine torque capacity signal. The multi-pulse enable module allows for the injection of at least two pulses of fuel into a cylinder during a combustion cycle, generating a multi-pulse desired signal based on various inputs. Additionally, the catalyst light-off torque reserve module generates a torque reserve corrected signal based on the multi-pulse desired signal.
Another significant patent is for "Diagnostic systems and methods for a pressure sensor during idle conditions." This diagnostic system includes a fuel pump module and a diagnostic control module. The fuel pump module activates a first pump and deactivates a second pump when the engine operates in a diagnostic mode. The diagnostic control module receives a measured pressure signal from a pressure sensor, detecting faults based on comparisons with commanded pressure signals.
