The invention concerns an architecture for a driving assistance system with conditional automation capable of controlling an automatic emergency stop of a vehicle, comprising: a set (2) of sensors of at least three different technologies for observing an area in front of a vehicle; a main computer (10) capable of receiving, via a first upstream data communication network, information from said set (2) of sensors, and of transmitting commands, via a first downstream communication network, to a first computer (3) of an engine control system, to a second computer (4) of a braking system and to a third computer (5) of a steering control system: a backup computer (11) capable of receiving, via a second upstream data communication network, information from said set of sensors in case of a failure relative to the main computer (10); a main power supply source linked to each computer; and a backup power supply source. The architecture comprises a second downstream communication network connecting only the backup computer (11) to said second computer (4) of the braking system for the transmission of commands, and the backup power supply source is connected only to the main computer (10), to the backup computer (11) and to the second computer (4) braking system.
