Abstract: A method for safety improvement during operation of a motor vehicle (100) includes the steps of:—determining a prevailing speed of the vehicle (100); automatically activating a warning flasher function (275) on the basis of determined values pertaining to at least some combination of conditions based on: vehicle speed (V) and gradient (L) of the running surface on which the vehicle (100) is travelling, and the speed of the vehicle (100) compared with surrounding traffic and the gradient (L) of the running surface on which the vehicle (100) is travelling. Also a computer program product including program code (P) for a computer (200; 210) for implementing the method is disclosed. Also a system for safety improvement during operation of a motor vehicle (100) and to a motor vehicle (100) which is equipped with the system are disclosed.

Abstract: A method at an exhaust gas cleaning system for an engine (235) in which a reducing agent is added to a passage (290) for exhaust gases from the engine (235) for cleaning the exhaust gases. The exhaust gas cleaning system includes arrangements (270) that require a certain temperature level (Tmax) in order to achieve catalytic exhaust gas cleaning. The method is to distribute and store (s430) a limited amount of reducing agent at temperature level (Tmax); and to use (s440) during a cold start of the exhaust gas cleaning system, the distributed and stored reducing agent to achieve the catalytic exhaust gas cleaning. Also a computer program product (200; 210) to implement the method. Also an arrangement for an exhaust gas cleaning system for an engine (235), and a motor vehicle (100) equipped with the arrangement.

Abstract: A method for an SCR system comprising a dosing unit (250) for dosing reducing agent into an engine exhaust duct (290) upstream of a SCR catalytic converter (270) for reducing the NOx level in an exhaust flow from the engine. The SCR system comprises a pressurizing device (230) for feeding reducing agent from a container (205) to the dosing unit (250) arranged so as to dose reducing agent to the exhaust duct (290) under pressure. The method includes the step of: reducing, during periods of non-continuous dosing of reducing agent during continued maintained operation of the pressurizing device (230), the pressure (s301; s320) of the reducing agent at the dosing unit (250) compared to the pressure during continuous dosing. Also a computer program product containing program code (P) for a computer (200; 210) for implementing a method according to the invention. The invention also concerns an SCR system and a motor vehicle that is equipped with that system.
