Abstract

A control arrangement for a vehicle motion system including a braking function, comprising motion actuators with one or more brake actuators pertaining to the braking function, a first vehicle motion management controller (VMM1) and a second vehicle motion management controller (VMM2), forming a redundant assembly to control the braking function, wherein, in riding conditions, the first vehicle motion management controller controls the brake actuators with a current nominal expected braking performance, while the second vehicle motion management controller (VMM2) is in a waiting-to-operate mode, the control arrangement comprising a hot swap functionality in which the second vehicle motion management controller (VMM2) is configured to take over control of the brake actuators from the first vehicle motion management controller, with the current nominal expected braking performance, in a short time period (SWT) less than one second, preferably less than 0.5 second, preferably less than 0.3 second, and associated control method.
