Abstract: A controller or processing system for a vehicle, such as a passenger service vehicle, the vehicle having at least one energy storage system, at least one alternator or other charging device coupled to and/or operable or driven by an engine or motor, wherein the alternator or other charging device is switchable between an operational state and a non-operational state by the controller or processing system responsive to one or more parameters of the vehicle. The invention also includes an associated vehicle and method. The parameters of the vehicle optionally include one or more or each of: acceleration of the vehicle, accelerator pedal position, vehicle speed, rotation speed of the engine, the gear currently selected and/or the current being drawn from, or load on, the at least one energy storage system and/or current being drawn by one or more or all electrical components of the vehicle and/or engine coolant temperature.

Abstract: A hand pole and socket arrangement (1) for use in a passenger service vehicle includes a hand pole (3) having a first end (2) and a first socket (4) for fitting to a passenger vehicle and for receiving the first end of the hand pole. The first end (2) of the hand pole and the first socket (4) are formed and arranged to prevent rotation of the hand pole relative to the socket when they are fitted together. A passenger service vehicle including the hand pole and socket arrangement (1) is also provided.

Abstract: Exhaust systems and passenger service vehicles, for example, buses are used together. The exhaust system can be arranged, in use, to be above an engine compartment. The exhaust system includes a first filter and a second filter, each filter having an inlet and an outlet. The inlets are inline with the respective first and second filters, and the outlets are transversely arranged with reference to the respective filters. Vehicles may have an overall length of about 35 feet or less and have an unladen weight of around 25,000 lbs or less.

Abstract: A passenger service vehicle includes one or more suspension mounts. Each suspension mount attaches a front axle to a chassis. In some cases, the axle is a drop beam axle. Each suspension mount is further mounted with one or more suspension components of the following: suspension arm links, suspension air springs, suspension dampeners, anti-roll bars and Panhard rods.

Abstract: There is disclosed a passenger service vehicle having an upper deck (100) and a lower deck (110), and a passenger staircase (400) extending between the upper deck and the lower deck. The staircase is positioned internal to the vehicle. In some examples, the staircase has at least an upper stair portion and a secondary stair portion, where the upper stair portion is connected to the upper deck and comprises at least one tread, and further connected to the secondary stair portion via an intermediate landing (420, 440), whereby the secondary stair portion extends parallel with respect to the length of the upper deck, and the upper stair portion extends transversely, and in some cases perpendicularly, with respect to the secondary stair portion. In some examples, the staircase comprises a lower stair portion. One embodiment envisages a U-shaped staircase. In some further examples, the staircase is described together with a fuel tank configuration.
