Latest Patents

One of his latest patents is titled "System and method for transmission clutch support on hybrid electric vehicle." This invention involves a vehicle system that implements a transmission clutch support mode during a stop of the vehicle. It includes a hybrid powertrain, a brake system, a clutch, and a controller. The hybrid powertrain consists of an internal combustion engine and an electric motor that provides motor torque to the driveline for propelling the vehicle. The brake system selectively provides brake torque to the drive wheels based on the application of a brake pedal. The clutch opens and closes to engage the powertrain with the driveline. The controller initiates the clutch support mode and determines whether a brake pedal release has been detected. It commands a brake hold that maintains brake pressure of the brake system after detecting the brake pedal release and commands the clutch to move to an engaged position while canceling the brake hold. This results in a concurrent blend-out of the brake torque and blend-in of the motor torque.

Another notable patent is "Control of user-selectable vehicle deceleration rate to maximize regeneration for electrified propulsion systems." This method includes operating an electrified powertrain in normal or maximum regeneration modes associated with lesser and greater electrical regeneration and vehicle deceleration rates, respectively. It involves receiving an input from a driver indicating a request to enable the maximum regeneration mode, detecting the status of the maximum regeneration mode, and operating the electrified powertrain accordingly. The system selectively outputs a message to the driver about the status of the maximum regeneration mode and commands a hydraulic brake system to generate brake force based on the driver-expected vehicle deceleration rate.
