Abstract: A differential control system for a motor vehicle such as a truck including at least one differential includes at least one differential lock which is able to operate the differential into at least a locked or an unlocked state, a controller that controls the differential lock, a manually operable control member freely rotating bidirectionally around at least one axis, an encoder connected to the control member to convert a rotation of the control member into a signal fed to the controller which controls the differential lock in order to operate the differential into a locked or an unlocked state.

Abstract: A lighting control system and a lighting control method to implement, in an automotive vehicle, external running lights in different available lighting configurations are provided. The lighting control method includes detecting at least one environment parameter, selecting among the different available lighting configurations and depending on the parameter, which lighting configurations can be implemented, depending on the parameter, defining in which order the selected lighting configurations are implemented when an input device is manually actuated, detecting a manual actuation on the input device, depending on a motion of the input device or a motion on the input device, implementing at least one lighting configuration that is chosen among the selected lighting configurations according to the implementation order.

Abstract: An apparatus for a vehicle having a multi-gear transmission includes an analogue tachometer display device indicating by continuously displacing a pointer against a graduated scale the number of revolutions per unit of time of a vehicle engine; a computer processing unit CPU receiving input signals representative of the actual engine speed and of the actual vehicle speed and determining at least one forecast engine speed corresponding to the actual vehicle speed, based on at least one speculated transmission gear ratio; and a gear indicator display adjacent to the graduated scale on which a current gear figure corresponding to the currently engaged gear is digitally displayed next to the current position of the pointer, and a speculated gear figure corresponding to the at least one speculated gear is digitally displayed next to the corresponding forecast engine speed on the graduated scale.
