Electronically controllable pneumatic braking system with failsafe braking application for autonomous driving, having only one shuttle valve

A vehicle comprising:

• a front axle;
• at least one rear axle;
• an electronically controllable pneumatic braking system having a first control unit for a primary system and a second control unit for a first fallback level, wherein said first control unit and said second control unit are configured to at least one of be supplied with energy independently of one another and at least partially replace one another in terms of function;
• said electronically controllable pneumatic braking system having a monostable fail-safety valve unit pneumatically connecting a main port, which provides a first pressure, and a failure brake port;
• said monostable fail-safety valve unit being connected both to said first control unit and to said second control unit and, in at least one of a fault situation, a power failure situation, and a diagnostic situation of said first control unit and said second control unit, provides a failure brake pressure at said failure brake port;
• and,
• wherein, in order to provide the failure brake pressure for triggering a failure braking operation of the vehicle, said failure brake port is connected to the primary system and/or to the first fallback level upstream of a functional pneumatic unit of at least one of said primary system and said first fallback level, such that both front axle service brake actuators and rear axle service brake actuators have a brake pressure applied thereto in order to implement the failure braking operation.
