A gearbox for a vehicle that includes a planetary gear with a ring gear, a sun gear and a planet gear carrier, on which at least one planet gear is rotatably mounted, which ring gear and sun gear are configured to engage with the at least one planet gear; a gearbox housing surrounding the planetary gear; an input shaft and an output shaft for the transfer of torque to and from the gearbox; a first axially movable coupling sleeve for selectively engaging and disengaging the planetary gear with/from the gearbox housing and for selectively engaging and disengaging the ring gear, the sun gear and the planet gear carrier with/from each other; and a second axially movable coupling sleeve for selectively engaging and disengaging the output shaft with/from the ring gear and with/from the planet gear carrier.

Gearbox for vehicles and vehicles comprising such a gearbox

A method and a system to control an auxiliary brake system in a vehiclehaving a service brake systemand an auxiliary brake system. Also a system for prevention of wheel lock when braking, which may deactivate a braking action provided by the auxiliary brake systemand may actively control a braking action provided by the service brake system. The system determines whether the vehicleis in a driving mode for which it is acceptable in terms of safety and/or drivability to block the deactivation of the braking action for the auxiliary brake system. If a first manual control, which is set up solely for activating braking action for the auxiliary brake system, is activated, this means it is acceptable, from a safety and/or drivability point of view, for the driving mode in question, to block the deactivation. Also arranging block deactivation for the auxiliary brake systemif it is acceptable in terms of safety and drivability to block it.
