Abstract: An optical lens system for vehicle lighting includes a light guide with optical elements arranged as indentations in a light impacting surface of the lens body. The optical elements are configured with a truncated cone section arranged within the lens body in connection to the light impacting surface, and a rounded cap section arranged within the lens body in connection to the truncated cone section. A base surface of the rounded cap section is coincident with a top surface of the truncated cone section. The truncated cone section has an outer surface and a base surface, and the rounded cap section includes an outer surface. A cross-sectional transition between the outer surface of the truncated cone section and the outer surface of the rounded cap section is non-linear.

Abstract: A transmission system avoids activation of a sailing functionality in a vehicle. The transmission system is configured for automatic gear-shifting in an automatic mode and manual gear-shifting by a user in a manual mode. The transmission system includes a user input device configured for manually changing the operational mode between the automatic and manual modes. The transmission system includes a transmission control unit for determining a recommended gear in the automatic and manual modes. In the manual mode, an operating gear of the transmission system is detected by the transmission control unit. A change of the operational mode from manual to automatic by means of the user input device is detected, and if the detected operating gear in the manual mode when changing to automatic mode is lower than the recommended gear, the sailing functionality in the automatic mode is deactivated.
