Abstract
Electrical system in a vehicle includes crash sensor systems each arranged to sense a crash involving the vehicle and occupant protection systems each including an occupant protection device arranged to protect an occupant in the event of a crash involving the vehicle. The crash sensor system(s) and the occupant protection system(s) are connected to a bus and supplied with power by the bus and communication through the bus. Each occupant protection device is actuated in the event of a crash involving the vehicle as sensed by a crash sensor system. Each occupant protection system may include a power supply for providing power to enable actuation of the occupant protection device, diagnostic circuitry for self-diagnosis, an occupant sensor and a controller for controlling actuation of the occupant protection device based on a signal received from a crash sensor system over the bus, and data from the occupant sensor.

11. An electrical system in a vehicle, comprising
a plurality of crash sensor means for sensing different types of crashes involving the vehicle; -
a plurality of occupant protection systems each including an occupant protection device arranged to protect an occupant in the event of a crash involving the vehicle;
a first bus, a discrete portion of said crash sensor means and a discrete portion of said occupant protection systems being coupled to said first bus and being supplied with power by said first bus and communication through said first bus, each of said occupant protection devices being actuatable in the event of a crash involving the vehicle as sensed by one of said crash sensor means; and
a second bus, a different discrete portion of said crash sensor means and a discrete portion of said occupant protection systems being coupled to said second bus and being supplied with power by said second bus and communication through said second bus, each of said occupant protection devices being actuatable in the event of a crash involving the vehicle as sensed by one of said crash sensor means, each of said crash sensor means and each of said occupant protection systems being either coupled to said first bus or to said second bus. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
