Braking assistance system for a vehicle and method for controlling a braking assistance system for a vehicle

The method involves releasing a control signal to a brake controller (30) through a connection (29a,32), which is physically independent from another connection (31). A brake control signal is generated by the brake controller depending on the control signals received through the two connections. The control signal is generated by converting a sensor signal from a sensor (23). An independent claim is also included for a brake assistance system for a vehicle.
