The Volvo Group is a Swedish multinational manufacturing company headquartered in Gothenburg. Its principal activity is the production, distribution and sale of trucks, buses and construction equipment. Volvo also supplies marine and industrial drive systems and financial services. Although the two firms are still often conflated, Volvo Cars, also based in Gothenburg, has been a totally separate company since it was sold off in 1999. The companies still share the Volvo logo and co-operate in running the Volvo Museum.Volvo was established in 1915 as a subsidiary of SKF, the ball bearing manufacturer, however the Volvo Group and Volvo Cars consider themselves to have been officially founded on 14 April 1927, when the first car, the Volvo ÖV 4 series, affectionately known as "Jakob", rolled out of the factory in Hisingen, Gothenburg.Volvo means "I roll" in Latin, conjugated from "volvere", in relation to ball bearings. The brand name Volvo was originally registered as a trademark in May 1911 with the intention to be used for a new series of SKF ball bearings. This idea was only used for a short period and SKF decided to simply use "SKF" as the trademark for all its bearing products.In 1924, Assar Gabrielsson, an SKF sales manager, and engineer Gustav Larson, the two founders, decided to start construction of a Swedish car. Their vision was to build cars that could withstand the rigors of the country's rough roads and cold temperatures.AB Volvo began activities on 10 August 1926. After one year of preparations involving the production of ten prototypes the firm was ready to commence the car-manufacturing business within the SKF group. AB Volvo was introduced at the Stockholm stock exchange in 1935 and SKF then decided to sell its shares in the company. Volvo was delisted from NASDAQ in June 2007, but remains listed on the Stockholm exchange. Wikipedia.

The present invention relates to a method for controlling an actuator (204) of a vehicle transmission (202), said actuator (204) being connected to an engaging sleeve (206), the engaging sleeve (206) being axially displaceable between a gear wheel disengaging position and a gear wheel engaging position of the vehicle transmission (202) for executing a transmission gear shift, wherein the method comprises the steps of actuating (S1) the actuator during a first predetermined time period (306) for initiating a translational movement of the engaging sleeve (206) from the gear wheel disengaging position towards the gear wheel engaging position, wherein the first predetermined time period (306) is smaller than a total time period (310) for the engaging sleeve (206) to reach the gear wheel engaging position; determining (S2), during a second predetermined time period (308) initiated after the duration of the first predetermined time period (306), if the engaging sleeve (206) has reached the gear wheel engaging position; and actuating (S3) the actuator (204) during a third predetermined time period (312) if it was determined that the engaging sleeve (206) failed to reach the gear wheel engaging position during the second predetermined time period (308). The invention also relates to a corresponding computer program, computer readable medium, control unit, and vehicle transmission.

The method comprises steps consisting in a) measuring the air pressure (P) of the air tank, b) if the air pressure (P) measured at step a) is inferior to a first threshold value (P1), assessing (102) whether the compressor is able to build up the air pressure (P) of the air tank, c) if the result of the assessment performed at step b) is that the compressor is unable to build up the air pressure (P) of the air tank, operating (306, 308) the braking system in a degraded mode wherein at least the electric actuator is used (306, 308) in case of braking (300), and d) if the air pressure measured at step a) is inferior to a second threshold value (P2), that is lower than the first threshold value, and if the compressor is unable to build up the air pressure (P) of the air tank, using (308) only the electric actuator in case of new braking actions (300).


The invention relates to an articulated vehicle having at least two vehicle parts which are connected to and articulated relative to each other. The vehicle comprises a front vehicle part and at least one rear vehicle part arranged behind the front vehicle part with respect to a longitudinal direction of the vehicle. The front vehicle part has a first drive unit comprising at least an electric motor and a first energy storage system; and at least one rear vehicle part has a drive unit comprising at least an electric motor and an energy storage system. Each rear vehicle part comprises an individual electrical system that is galvanically isolated from the front vehicle part and from each other at least under normal driving conditions.


The invention relates to a method for controlling charging of an electric energy storage system (7) in a vehicle (1) comprising an electric machine (3) which is arranged for propulsion of said vehicle (1). The method comprises: initiating said charging upon connection of said energy storage system (7) to an external power supply (11) via a first connector element (9) associated with said vehicle (1) and a second connector element (10) associated with said external power supply (11); and monitoring a contact resistance defined by the connection of said connector elements (9, 10). Furthermore, the method comprises: measuring and calculating the power loss over said connector elements (9, 10) during said charging; and generating an error signal if said power loss is higher than a predetermined threshold value, said error signal being dependent on the magnitude of said power loss. The invention also relates to an arrangement for controlling charging of an electric energy storage system (7) in a vehicle (1).

The present invention relates to a self-adjusted side fairing assembly including a first side faring, a second side fairing, and biasing members. The first side fairing is adapted to be located at a trailing edge of a body on a lead vehicle. The second side fairing is adapted to be located at an opposing trailing edge of the body on the lead vehicle. The first and second side fairings have self-adjusting directional airflow characteristics in response to windward side and leeward side crosswind characteristics. The first and second side fairings are adapted so that trailing ends of the first and second side fairings pivot outward due to the effect of a high external pressure that is greater than high pressure threshold and generated by windward side crosswind characteristics.

In an embodiment, the route to be followed is determined based on the forecasted fuel consumption.


The present invention relates to the field of methods performed by control units for managing energy flows within an energy system of a vehicle. The energy system comprises a plurality of energy subsystems connected by converters. The converter can convert energy of one energy form from one energy subsystem to energy of another energy form of another energy subsystem. At least one energy subsystem comprises an energy buffer. According to the method performed by a control unit vehicle travel route information is collected for a predefined travel route whereby the travel route can be divided in part routes. By estimating an energy consumption over respective part route for each energy buffer an estimated energy buffer price for respective part route can be calculated by the control unit. The estimated energy buffer price can subsequently be used such that energy can be provided between energy subsystems such that the available energy for a part route can be distributed within the energy system of the vehicle in the most efficient way by the control unit and the usage of respective energy buffer can be optimized.
