1. A vehicle system for a vehicle, the vehicle system comprising:
an electronically controllable pneumatic braking system;
an electronically controllable steering device;
said electronically controllable pneumatic braking system having at least one first brake circuit, at least one second brake circuit, and an electronic central control unit for electronically controlling the first brake circuit and the second brake circuit;
said electronically controllable pneumatic braking system further having a plurality of front axle brake actuators including a first front axle brake actuator and a second front axle brake actuator for a first front wheel and a second front wheel at least at one front axle;
said electronically controllable pneumatic braking system further having a plurality of rear axle brake actuators including a first rear axle brake actuator and a second rear axle brake actuator for a first rear wheel and a second rear wheel at least at one rear axle;
said electronic central control unit being connected to an electronic stability control;
said electronic stability control being configured to wheel-individually actuate at least one of said plurality of front axle brake actuators and said plurality of rear axle brake actuators;
said electronically controllable pneumatic braking system further having a redundant electronic control unit configured to electronically control at least one of said first brake circuit and said second brake circuit in response to a failure of the electronic stability control during a trip of the vehicle;
wherein, in the event of the failure of the electronic stability control during the trip of the vehicle, said redundant electronic control unit is configured to perform axle-wise electronic control of at least one of the at least one front axle with a front axle redundancy brake pressure and the at least one rear axle with a rear axle redundancy brake pressure; and,
wherein said electronically controllable steering device is configured to carry out a laterally stabilizing steering intervention causing the vehicle to stay in a tolerance corridor of a predefined target trajectory of the vehicle.
