A powertrain assembly includes a transmission, an engine, first and second motor/generators and a controller. The controller includes a processor and memory on which is recorded instructions for executing a method for controlling engine pulse torque cancellation commands. The controller is programmed to determine an engine pulse torque (T.sub.P). The controller is programmed to calculate a first motor torque pulse command (T.sub.A) for the first motor/generator as a product of a first gear factor (G.sub.1), the engine pulse torque (T.sub.P) and a first ratio (I.sub.A/I.sub.E) of a predetermined first moment of inertia (I.sub.A) for the first motor/generator and a predetermined engine moment of inertia (I.sub.E). Similarly, the controller is programmed to calculate a second motor torque pulse command (T.sub.B) for the second motor/generator. The controller is programmed to control the first and second motor/generators in response to the first and second motor torque pulse commands, respectively.

The invention relates to a method for controlling a drivetrain having an internal combustion engine controlled dependent on a load demand on a target engine torque and having a dual-clutch transmission with two sub-transmissions, each having a friction clutch positioned operatively between the internal combustion engine and a sub-transmission with a changing maximum transferable clutch torque, wherein a specified clutch torque is set along an actuation travel path by means of a clutch actuator, a clutch characteristic of the transferable clutch torque is continuously adapted over the actuation travel path, and a maximum engine torque for a sub-transmission, which is reduced in comparison to the target engine torque, is limited to the maximum clutch torque transferable by means of the friction clutch of that sub-transmission.

A driving force control system according to an embodiment of the present invention includes: an absolute bank angle detector configured to detect an absolute bank angle that is the absolute value of a vehicle's bank angle; a calculation circuit configured to calculate a relative bank angle that is the vehicle's relative angle with respect to a maximum absolute bank angle that is the maximum value of the absolute bank angle; and a controller configured to control driving force based on the relative bank angle.

A method is described for shutting off an internal combustion engine in a vehicle that comprises an internal combustion engine and an electrical machine, an electrical torque furnished by the electrical machine being adapted in such a way that a change per unit time in a total torque lies within a definable range, the total torque being made up at least of a torque of the internal combustion engine and the electrical torque.

A vehicle control device controls a vehicle including a drive motor connected to a rotation shaft of wheels, a battery that supplies electricity to the drive motor, and an internal combustion engine connected to the drive motor. The vehicle is equipped with, as traveling modes, a normal mode, and an eco-mode having a larger regenerative braking force than the normal mode obtained such that rotational energy of the wheels is converted into electrical energy. A controller stops the internal combustion engine and switches from the normal mode to the eco-mode when detecting at least an abnormality in the internal combustion engine during traveling of the vehicle.

A method for starting a combustion engine of a hybrid motor vehicle drivetrain, in which there is a connection clutch interposed between the combustion engine and the electric motor for transmitting a torque between the combustion engine and the electric motor, and a main clutch interposed between the gearbox and the electric motor. From an initial state in which the electric motor generates a drive torque and the combustion engine is stopped, the main clutch is kept in a closed state so as to transmit the torque generated by the electric motor to the gearbox, and the connection clutch is controlled so as to transmit a drive torque between the electric motor and the combustion engine and perform a torque-limiting function between the combustion engine and the electric motor in order to limit the transmission of acyclisms between the combustion engine and the electric motor.

A hybrid-vehicle system includes an internal combustion engine configured to deliver a first rotational torque to a crankshaft. The first rotational torque is a maximum torque deliverable by the internal combustion engine. The hybrid-vehicle system also includes a transmission selectively rotatably coupled to the crankshaft, and an assembly including an electric machine rotatably coupled to the transmission and configured to deliver a second rotational torque directly to the transmission. The assembly also includes a one-way clutch configured to rotationally couple the crankshaft and the transmission. The assembly further includes a friction clutch moveable between an engaged state where the crankshaft and the transmission are rotationally coupled, and a disengaged state where the crankshaft and the transmission are rotationally decoupled. The friction clutch is further defined as a latching friction clutch.

A slip control method and arrangement for a drivetrain including a continuously variable transmission, forward-reverse clutch arrangement and an optional three-speed gearbox is described herein. The forward-reverse clutch arrangement includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. Accordingly, the clutch prevents the prime mover from stalling.

Various applications for use of mass estimations of a vehicle, including to control operation of the vehicle, sharing the mass estimation with other vehicles and/or a Network Operations Center (NOC), organizing vehicles operating in a platoon and/or partially controlling the operation of one or more vehicles operating in a platoon based on the relative mass estimations between the platooning vehicles. When vehicles are operating in a platoon, the relative mass between a lead and a following vehicle may be used to scale torque and/or brake commands generated by the lead vehicle and sent to the following vehicle.

A working vehicle includes a prime mover, a traveling device, a traveling clutch switchable between an engaged state to transmit, to the traveling device, power provided from the prime mover and a disengaged state to interrupt the power transmitting to the traveling device, an automatic switching controller to switch the traveling clutch from the disengaged state to the engaged state, and a status detector to detect at least either a status of the prime mover or a status of the traveling device. The automatic switching controller changes a switching speed of the traveling clutch switched from the disengaged state to the engaged state based on the status detected by the status detector.
