Method And System For Vehicle Cooling Systems

View page
US Patent:
20220266680, Aug 25, 2022
Filed:
Feb 22, 2021
Appl. No.:
17/181813
Inventors:
- Dearborn MI, US
Hassan Farhat - Dearborn MI, US
Rajit Johri - San Francisco CA, US
Ravi Gopal - Novi MI, US
International Classification:
B60K 11/06
H02P 21/13
F01P 7/04
F01P 7/16
Abstract:
Methods and system for operating a vehicle cooling system are described. In one example, the vehicle cooling system cools a heat generating device via a fan and pump. A speed of the fan is commanded by a feedback controller with possible neural network predictive control to track a variable temperature reference that is based on thermal load estimation. A disturbance observer may be applied to observe thermal load and an observer-based observer may be used to generate the temperature reference so that the power consumption of a fan is minimized.

US Patent:
20230097669, Mar 30, 2023
Filed:
Sep 28, 2021
Appl. No.:
17/449209
Inventors:
- Dearborn MI, US
Akshay Bichkar - Ann Arbor MI, US
Jason Meyer - Canton MI, US
Rajit Johri - San Francisco CA, US
International Classification:
B60W 10/06
B60W 10/08
B60W 10/02
B60W 20/40
B60K 6/48
Abstract:
Systems and methods for operating a hybrid vehicle are described. In one example, the automatic engine stopping may be inhibited so that an engine may be restarted during change of mind conditions without generating a large driveline torque disturbance. The engine stopping may be inhibited based on a inhibit engine pull-down torque threshold.

Methods And System For Reserving Torque For Engine Starting

US Patent:
20230099071, Mar 30, 2023
Filed:
Sep 28, 2021
Appl. No.:
17/449216
Inventors:
- Dearborn MI, US
Ravikumar Tumu - Westland MI, US
Jason Meyer - Canton MI, US
Rajit Johri - San Francisco CA, US
Jeffrey Allen Doering - Canton MI, US
International Classification:
F02N 11/08
F02N 11/04
Abstract:
Systems and methods for operating a hybrid vehicle are described. In one example, a torque reserve for starting an engine via an electric machine is adjusted responsive to vehicle operating conditions. The torque reserve may set aside a portion of torque that an electric machine may produce for cranking and starting an engine.

US Patent:
20230031444, Feb 2, 2023
Filed:
Jul 28, 2021
Appl. No.:
17/443925
Inventors:
- Dearborn MI, US
Calvin Trescott - Farmington Hills MI, US
Jason Meyer - Canton MI, US
Rajit Johri - San Francisco CA, US
Jeffrey Doering - Canton MI, US
International Classification:
F02N 11/08
F02N 11/04
F02N 5/04
Abstract:
Systems and methods for starting an engine of a hybrid vehicle are described. In one example, the method selects one or more electric machines to start an engine. The method may reference a data structure, such as a matrix or table, and the matrix or table outputs which of the one or more electric machines is applied to start the engine.

Torque Control System For A Vehicle Powerplant

US Patent:
20210354681, Nov 18, 2021
Filed:
May 18, 2020
Appl. No.:
16/876841
Inventors:
- Dearborn MI, US
Maruthi Thiruninravur Ravichandran - Hamilton, CA
Jason Meyer - Canton MI, US
Rajit Johri - Canton MI, US
Jeffrey Allen Doering - Canton MI, US
Yanan Zhao - Ann Arbor MI, US
International Classification:
B60W 10/02
F16H 45/02
B60K 23/06
Abstract:
A vehicle includes a drive wheel, an engine, an accelerator pedal, a torque converter, a clutch, and a controller. The drive wheel is configured to propel the vehicle. The engine is configured to generate power and to deliver power to the drive wheel to accelerate the vehicle. The accelerator pedal is configured to generate an acceleration request based on a pedal position. The torque converter is disposed between the engine and the drive wheel. The clutch is disposed between the engine and the drive wheel and is configured to bypass the torque converter. The controller is programmed to, in response to depressing the accelerator pedal to a position that corresponds with accelerating the vehicle at a desired magnitude, adjust the torque of the engine to accelerate the vehicle at the desired magnitude, regardless of the state of the clutch.

US Patent:
20210300316, Sep 30, 2021
Filed:
Mar 25, 2020
Appl. No.:
16/829291
Inventors:
- Dearborn MI, US
Kevin Ray Ruybal - Canton MI, US
Jason Meyer - Canton MI, US
Mark Steven Yamazaki - Canton MI, US
Rajit Johri - Canton MI, US
Ming Lang Kuang - Canton MI, US
International Classification:
B60W 10/06
B60W 10/08
B60W 30/192
B60W 10/02
B60K 6/387
Abstract:
A method for operating a vehicle that may be automatically stopped and started is described. In one example, the method includes starting an engine via expansion stroke combustion in response to a request to urgently start the engine. In addition, the method includes adjusting a position of a compression relief valve in response to a predicted urgency of an engine start.

Method For Operating A Vehicle Having A Driveline Disconnect Clutch

View page
US Patent:
20210245751, Aug 12, 2021
Filed:
Feb 10, 2020
Appl. No.:
16/786073
Inventors:
- Dearborn MI, US
Rajit Johri - Canton MI, US
Shailesh Shrikant Kozarekar - Novi MI, US
Thomas Scott Gee - Canton MI, US
Ming Lang Kuang - Canton MI, US
Kevin Ray Ruybal - Canton MI, US
International Classification:
B60W 30/188
B60W 20/15
B60W 40/13
Abstract:
A method for operating a vehicle that includes a driveline disconnect clutch is described. In one example, the method adjusts torque of an electric machine in response to a estimated torque capacity of the driveline disconnect clutch. The estimated torque capacity of the driveline disconnect clutch is based on a combined inertia of a dual mass flywheel and the driveline disconnect clutch.

Systems And Methods For Torque Shaping

US Patent:
20210215211, Jul 15, 2021
Filed:
Jan 13, 2020
Appl. No.:
16/741021
Inventors:
- Dearborn MI, US
Jason Meyer - Canton MI, US
Rajit Johri - Canton MI, US
Jeffrey Allen Doering - Canton MI, US
International Classification:
F16D 48/10
B60W 50/10
F16H 57/12
Abstract:
A vehicle includes controller programmed to receive a driver-demanded wheel torque command and calculate a shaped wheel torque command based on the driver-demanded wheel torque command. The controller is further programmed to, in response to the driver-demanded wheel torque command changing from a first magnitude that is greater than an estimated wheel torque at a last time step to a second magnitude that is less than the estimated wheel torque at a current time step, set the shaped wheel torque to a minimum of a magnitude of the shaped wheel torque at the last time step and an estimated wheel torque at the current time step. The controller is also programmed to command the first and second actuators to produce the shaped wheel torque.
