    Abstract: A method for controlling operation of a hydraulic valve having a magnet fixed to a displaceable spool, a sensor producing a signal responsive to the sensed intensity of a field produced by the magnet representing the position of the spool in the valve spool, the method comprising producing from the signal a time series record of the position of the spool; determining the desired position of the spool, producing a error signal from the difference between actual and desired spool position, determining a compensated correction error, producing a commanded control pressure signal to change the magnitude of control pressure supplied to the valve, and changing the position of the spool in response to the control pressure signal.

    Abstract: A vehicle has an engine, an upstream clutch, an electric machine, a downstream clutch, a transmission gearbox, and a controller. The controller is configured to: (i) control engagement of the downstream clutch, (ii) monitor a vehicle torque, and (iii) control electric machine torque to a designated rate when the vehicle torque changes direction and the electric machine is operating. A method for controlling a hybrid vehicle includes engaging a clutch downstream of the electric machine, monitoring a vehicle torque, and controlling electric machine torque to a designated rate when vehicle torque changes direction and the electric machine is operating. A hybrid vehicle system has an electric machine and a controller configured to (i) control electric machine torque to a designated rate within a time zone, and (ii) control at least one of the electric machine torque and an engine torque to meet driver demand outside of the zone.

    Abstract: A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine at the lowest engine speeds when the engine-required torque is the highest. This reduces the amount of torque necessary to be supplied from the motor/generator, and further helps to reduce torque disturbances in the driveline. If the motor/generator is producing torque to propel the vehicle at the time the engine start is requested, a launch clutch or one or more transmission clutches can be controlled to provide slip between the motor/generator and the vehicle drive wheels to further reduce torque disturbances in the driveline.
