TRANSMISSION PLATFORM METHOD AND DEVICES
The embodiments disclose a method including separating kinetic speed from energy using a transmission platform, directing energy in the kinetic form at a predetermined speed from 0 to 100%, employing the transmission platform with fewer pieces to increase overall efficiency at a lower cost to produce, and integrating the transmission platform with combustion engines and electric motors to achieve more efficiency and greater performance.
Slip control method and arrangement for a drivetrain architecture including a continuously variable transmission
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.

On demand machine rimpull adjustment to prevent tire slip
A system for proactively controlling rimpull limit of a machine includes a hydraulic system having a lift cylinder to move an implement; a lift cylinder pressure sensor that senses a hydraulic pressure of the lift cylinder and responsively produces a lift cylinder pressure signal; and a controller in operable communication with the power train and the lift cylinder pressure sensor. The controller is configured to receive the lift cylinder pressure signal; determine the rimpull limit based at least in part upon the lift cylinder pressure signal; and adjust the torque of the power train to the rimpull limit.
Vehicle control device
The present invention realizes a vehicle control device that, even when power characteristics of a power generation device and a power transmission device changes, senses degradation of vehicle components, corrects a drive instruction to the power transmission device, and is thereby capable of stabilizing vehicle behavior over a long term. The present invention, in a predetermined vehicle environment state, measures fluctuation in drive power and acceleration in a transient region by using vehicle behavior sensors 4, performs comparison with a reference fluctuation, and thereby senses degradation of vehicle components. The drive instruction to the transmission 16-side is corrected in accordance with the degradation of vehicle components that is sensed. Thus, it is possible to stabilize vehicle behavior (performance) over a long term even when, during automated driving, the power characteristics of the drive power source and the transmission 16 change due to factors such as time degradation of vehicle components.

CONTROL DEVICE FOR VEHICLE AND CONTROL METHOD FOR VEHICLE
A control device for a vehicle having: an engine; a variator arranged downstream of the engine in a power transmission path connecting the engine and drive wheels; a mechanical oil pump that is driven by the engine and supplies hydraulic pressure to the variator; and an electric oil pump that supplies hydraulic pressure to the variator, wherein the control device for the vehicle has a controller that executes a low standby control which downshifts the variator by moving a belt of the variator in a radial direction during stopping of the vehicle. The controller limits an output of the engine and increases an amount of oil discharged by the electric oil pump when executing the low standby control.

A control device for a vehicle having: an engine; and a variator arranged downstream of the engine in a power transmission path connecting the engine and drive wheels, wherein the control device for the vehicle has a controller that executes a low standby control which downshifts the variator by moving a belt of the variator in a vertical direction (radial direction) during stopping of the vehicle. After starting the low standby control, the controller releases an output limit of the engine based on an actual secondary pressure of the variator.
