Abstract: In a first aspect, this specification describes a method which comprises receiving, at a stationary vehicle, a user input to cause the vehicle to enter an autonomous mode; highlighting, by a portable user device, subsequent to the vehicle entering the autonomous mode and prior to the vehicle moving, a target location; receiving, by the vehicle, an indication of the target location and a request to travel to the target location; and causing the vehicle to autonomously travel to the target location without human supervision.

Abstract: A method of controlling a range extender of an electric vehicle comprises using actual measured or modelled pollution levels dynamically to set a target state of charge level for a range extender of an electric vehicle at a particular location.

Abstract: A range extender for a vehicle, comprises an electric machine; an engine; and a controller, wherein the controller is configured to control fuelling of the engine, and is configured to control the electric machine to charge a battery of the vehicle using power from the engine and at other times to control the electric machine to drive the engine using power from the battery, wherein the controller is configured to increase the engine speed by controlling the electric machine to drive the engine using power from the battery whilst substantially not fuelling the engine.
