US Patent:

20190299977, Oct 3, 2019
Filed:

Mar 25, 2019
Appl. No.:

16/363299
Inventors:

Sathya Manivasagam - Bloomfield Hills MI, US
Behrouz Ashrafi - Northville MI, US
Feisel F Weslati - Troy MI, US
International Classification:

B60W 20/50
F16H 63/34
B60W 10/196
B60W 10/18
G07C 5/08
B60W 10/06
B60W 10/08
Abstract:

Systems and methods for controlling a park pawl system of a hybrid vehicle having a hybrid powertrain comprising an engine and a hybrid transmission comprising at least one electric propulsion motor, the systems and methods each utilizing a control system configured to detect, using a main control system portion, a desired park state based on at least an input via a transmission gear selector and an input via a brake pedal and detect, using a distinct monitoring system portion, whether the desired park state is valid based on at least the transmission gear selector and brake pedal inputs. When the desired park state is valid, the control system commands the park pawl system to the desired park state. When the desired park state is invalid, however, the control system commands an electric park brake of the vehicle to prevent movement at a driveline of the vehicle.

Appl. No.:

15/885083
Inventors:

Behrouz Ashrafi - Northville MI, US
Feisel F. Weslati - Troy MI, US
Sathya Manivasagam - Bloomfield Hills MI, US
International Classification:

B60W 20/10
B60W 10/08
B60W 10/192
B60W 50/10
Abstract:

A control system and method for a hybrid vehicle involve controlling a hybrid powertrain comprising an engine and a transmission having one or more electric motors and not comprising a decoupling mechanism therebetween, detecting an operating condition where the transmission is in neutral and the vehicle is moving at a speed less than a low speed threshold, and in response to detecting the operating condition: determining a desired propulsive torque of the powertrain, determining an actual propulsive torque at the driveline, calculating a torque difference between the actual and desired propulsive torques over a period, comparing the calculated torque difference to a first movement threshold, and when the calculated torque difference exceeds the first movement threshold, applying an electric parking brake (EPB) of the vehicle.
