A method of acquiring information of an accessory connected to a vehicle. The method comprises, in a control unit of the vehicle, acquiring an accessory identifier from the accessory. The method further comprises transmitting the accessory identifier to a remote server comprising accessory information, matching, in the server, the accessory identifier with corresponding accessory information, transmitting the accessory information to the vehicle and receiving the accessory information in the control unit.

Method and system for acquiring information about an accessory of a vehicle

The invention relates to a method of acquiring information of an accessory connected to a vehicle. The method comprises, in a control unit of the vehicle, acquiring an accessory identifier from the accessory. The method further comprises transmitting the accessory identifier to a remote server comprising accessory information, matching, in the server, the accessory identifier with corresponding accessory information, transmitting the accessory information to the vehicle and receiving the accessory information in the control unit.

A method and device for evaluating the capacity of a compressor () by air being allowed to flow out from a pressure tank () through an opening of known geometry. Following a calculation, the quantity of evacuated air is obtained. After this, a compressor () pumps back up to the initial pressure in the pressure tank (). The compressor capacity () is established by comparing the time it takes for the compressor () to pump back up to the initial pressure in the pressure tank () with the time it takes when an acceptable compressor () pumps the same quantity of air. By the compressor capacity () is here meant the quantity of air which the compressor () delivers per unit of time at a given compressor speed and counter-pressure.
