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.

A vehicular shift operation apparatus that includes a manual transmission including an input-side sub-transmission and an output-side sub-transmission, and that is capable of preventing overrun or underrun due to erroneous shift operation, is provided. The vehicular shift operation apparatus includes a manual transmission including an input-side sub-transmission and an output-side sub-transmission, and includes: a main shaft rotation speed sensor that detects a main shaft rotation speed, a sensor that detects a position of a clutch pedal, and a controller. The controller has a function of detecting a gear stage at a control cycle (current gear stage) and a function of determining whether the detected gear stage is correct or not.

An oil level gauge device in which an oil level gauge is inserted in a guide pipe communicating with an oil pan, is provided. In the oil level gauge, a cap having a plug configured to fit on an inner peripheral surface at one end portion of the guide pipe, and a flange integrally formed with the plug and abutted with the one end of the guide pipe, is provided. A groove extending from a deeply inserted side of the plug to an abutment surface of the end abutting the flange is formed in the inner peripheral surface. When the plug is fitted on the inner peripheral surface, a ventilation passage for communicating the inside and outside of the oil pan through the guide pipe is formed between the plug and the guide pipe by the groove.

A bellows for protecting a U-joint in a marine stern drive includes a flexible, hollow body defining an interior space and open at opposite ends, the body formed of a thermoplastic elastomer material to be self-supporting, having a first mating end and a second mating end and being pleated therebetween, a first sealing cuff formed of an elastomeric material, softer than the thermoplastic elastomer material, bonded to the first mating end and, a second sealing cuff formed of an elastomeric material, softer than the thermoplastic elastomer material, bonded to the second mating end.

A method for controlling a reductant buffer level in an exhaust gas after treatment device connectable downstream of an internal combustion engine includes performing a first reductant injection of a first amount upstream the exhaust gas after treatment device, performing a second reductant injection of a second amount upstream the exhaust gas after treatment device, which second amount is different to the first amount, evaluating the NOx conversion resulting from the first and second reductant injections downstream the exhaust gas after treatment device to obtain a first and second result, controlling a further reductant injection in dependence of the first and second results from the first and second NOx conversion evaluations.

A method for entering a preceding vehicle autonomous following mode includes the steps of registering and identifying at least one preceding vehicle in front of a host vehicle by at least a first and a second sensor device, comparing the preceding vehicle with vehicle data in a remote database system, and upon a match establishing a communication channel between the preceding vehicle and the host vehicle, identifying to an operator of the host vehicle preceding vehicles with which the communication channel has been established, and obtaining from the operator a selection of a target vehicles to engage following of Finally, autonomous following mode of the target vehicle is engaged, wherein a vehicle control system automatically controls at least the following three main functions of the host vehicle: forward propulsion, steering, and braking.
