Abstract:
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 while 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.
