20140032026 | HYBRID ELECTRIC VEHICLE CONTROLLER AND METHOD OF CONTROLLING A HYBRID ELECTRIC VEHICLE - Embodiments of the invention provide control means for a hybrid electric vehicle (HEV) operable to control first and second actuators of a vehicle to deliver motive torque to drive a vehicle, the control means being operable to control a vehicle to transition between a first mode in which a first actuator is substantially disconnected from a driveline of a vehicle and a second actuator delivers motive torque to drive a vehicle and a second mode in which a first actuator is connected to a driveline by means of a releasable torque transmitting means and the control means controls first and second actuators to deliver respective first and second actuator target torque split values to drive a vehicle thereby to provide a driver demanded drive torque, when a transition from the first mode to the second mode is required the control means being configured to control rotation of a first actuator by means of a speed control means towards a target first actuator speed and to control a releasable torque transmitting means to transition between an actuator disconnected condition and an actuator connected condition thereby to connect a first actuator to a driveline, the control means being further configured to ramp an amount of torque delivered by a first actuator towards a first actuator target torque split value, and to ramp an amount of torque delivered by a second actuator towards a second actuator target torque split value whilst retaining a total drive torque value provided to a vehicle substantially equal to a driver demanded torque, wherein the target first actuator speed is a speed greater than a speed at which a first actuator would rotate with a releasable torque transmitting means in the actuator connected condition. | 01-30-2014 |
20140026841 | COMPOSITE CYLINDER BLOCK OF AN I.C. ENGINE - A composite cylinder block comprises an inner component defining one or more cylinder bores and main bearing supports of a crankshaft, and an outer component defining an upper crankcase, the inner component being inserted in the outer component, and being rigidly attached thereto. The arrangement provides a comparatively lightweight and rigid cylinder block. | 01-30-2014 |
20140025244 | HYBRID ELECTRIC VEHICLE AND METHOD OF CONTROLLING A HYBRID ELECTRIC VEHICLE - A hybrid electric vehicle (HEV) controller configured to determine a value of driver demanded torque to be supplied to a driveline of a HEV by first and second actuators of the vehicle based on a plurality of parameters, the parameters including: (a) a speed of a first actuator; and (b) a position of a driver-operated control, the controller being configured such that when the first actuator is not connected to the driveline a value of driver demanded torque is determined based on a virtual speed of the first actuator, the virtual speed being a speed at which the first actuator would be turning if the first actuator was connected to the driveline. | 01-23-2014 |
20140024492 | HYBRID ELECTRIC VEHICLE CONTROLLER AND METHOD OF CONTROLLING A HYBRID ELECTRIC VEHICLE - Embodiments of the invention provide control means for a hybrid electric vehicle, the control means comprising an energy management portion (EMP) configured to determine a required torque split between each of a first and at least a second actuator in dependence on a first set of one or more vehicle parameters, the required torque split being an amount of torque required to be provided to drive the vehicle by each actuator, the control means being configured to provide an actuator request control output whereby each actuator is controlled to provide an amount of torque according to the required torque split, the control means further comprising a powertrain mode manager (PMM) portion, the PMM portion being arranged to override the control output of the EMP in dependence on a value of a second set of one or more vehicle parameters. | 01-23-2014 |
