摘要： Systems and methods for monitoring electrified vehicle powertrain propulsive torque and taking remedial action when needed involve continuously monitoring an error between the actual and requested propulsive torques and comparing the error to various threshold values. Error exceeding a particular threshold could be indicative of a malfunction, and the vehicle could be afforded an opportunity to regain equilibrium by temporarily decreasing torque output. When the error continues to exceed the threshold or another threshold, however, further remedial action could be required, such as shutting down the vehicle.

摘要： Powertrain propulsive torque monitoring and remedial action techniques for a cruise control mode of an electrified vehicle comprise obtaining a set of inputs indicative of a driver torque request and a state/grade of a road along which the vehicle is traveling, operating in a cruise control mode including determining a total torque request for an electrified powertrain, determining and commanding a distribution of the total torque request to the electrified powertrain, and determining the road state/grade based on at least some of the set of inputs, and monitoring the operating in the cruise control mode including determining an actual torque being generated by the electrified powertrain, determining upper and lower acceptable torque limits for the cruise control mode based on the road state/grade, and taking remedial action regarding the cruise control mode when the actual torque is outside of the upper and lower acceptable torque limits.

摘要： A modular electrically variable transmission includes at least one of a sun-shared module and a sun and ring-shared module assembled to form a two-module electrically variable transmission having a shiftable motor speed reducer subassembly and an electrically variable transmission subassembly. The sun-shared module includes a first motor-generator, an input, and primary and secondary planetary gear sets each having respective primary and secondary ring gears, carriers and associated pinion gears. The pinion gears are in meshing engagement with a single first shared sun gear that is non-rotatably coupled to the first motor-generator. The sun and ring-shared module includes a second motor-generator, a second input, a second shared sun gear and a shared ring gear, and primary and second secondary planetary gear sets. The secondary planetary gear set includes a secondary carrier supporting outer and inner pinion gears. The second shared sun gear is non-rotatably coupled to the second motor-generator.

摘要： 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.

摘要： 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.
