Abstract: A method for checking a capacity of at least one supply line for an electrically operated assembly that is coupled electrically via the at least one supply line to an electrical system of an at least partially automated mobile platform. The method includes: ensuring a non-critical operating state of the mobile platform; determining an off-load terminal voltage at an input connection of the assembly, with zero-current supply line; applying a defined current to the supply line of the electrically operated assembly; determining an on-load terminal voltage at the input connection of the assembly, in doing so, the defined voltage being applied to the supply line of the electrically operated assembly; determining a differential voltage between the off-load terminal voltage and the on-load terminal voltage; comparing the differential voltage to a differential-voltage limit value to determine whether the capacity of the electric supply line is sufficient to operate the assembly.

Abstract: A brake system for hydraulically actuating a pair of front wheel brakes and a pair of rear wheel brakes includes master cylinder fluidly connected to a reservoir and operable to provide a brake signal responsive to actuation of a brake pedal connected thereto. The master cylinder is selectively operable in a manual push-through mode. First and second power transmission units are in fluid communication with the reservoir and selected front and rear wheel brakes. An electronic control unit selectively controls at least one of the first and second power transmission units. First and second two-position three-way valves are each hydraulically connected with a respective power transmission unit, the master cylinder, and a respective front wheel brake. The first and second two-position three-way valves are configured to place the master cylinder in push-through fluid-supplying connection with at least a corresponding one of the pair of front wheel brakes.
