Latest Patents

One of his latest patents is titled "Brake-dependent clutch holding pressure while transmission is in neutral." This invention involves systems and methods for performing a garage shift of an automatic transmission. It maintains a clutch at a first holding pressure while the transmission is in neutral and a brake input signal meets a certain threshold. This innovation aims to mitigate or eliminate the transfer of drive torque from the vehicle's torque generating system to its driveline when the transmission is in neutral. The garage shift is executed when the brake input signal satisfies the threshold and a shift from neutral to a non-neutral gear is requested.

Another notable patent is "Vehicle transmission hydraulic circuit fill time learn." This system controls transmission shifting by utilizing a controller that receives a shift request signal. It determines if a clutch has been unapplied for more than a predetermined time. The system then calculates a maximum fill time value for hydraulic fluid to be applied to a clutch control circuit, which is influenced by the time the clutch has been unapplied and the temperature. This innovation helps reduce air in the control circuit and minimizes flare during subsequent transmission shifts.
