Ch26 Onboard Vehicle Networks Questions with 100%
Verified Answers UPDATED!!!
Onboard vehicle networks are formed by - ANSWER Connecting
vehicle electronic control modules to one another to
communicate and exchange information.
Communication takes place between all the modules and
devices connected to the network using - ANSWER An electrical
signal-processing strategy called multiplexing (MUX).
Onboard networks can be categorized by - ANSWER Typology,
their physical layer, their network protocol, or by whether they
have centralized or distributed control.
Networks are formed based on organizational priorities, with
modules grouped by - ANSWER Area or function, such as those
involved in engine, transmission, ABS, climate control,
instrumentation, entertainment devices, or body electrical
control.

The type of multiplexing used in onboard networks works by -
ANSWER dividing the time available to each network module or
device to transmit and listen to information. Only one module is
allowed to talk, and all other modules must listen until it is their
turn to talk.
Advantages of multiplexing include - ANSWER Simplified
software control of the electrical system, to enable onboard
diagnostics, ease of connecting electronically controlled
accessories and features, and reduction in number of sensors.
Controlled area networks are the most - ANSWER Widely used
type of network for integrating power train operation (PTO) of
all the latest vehicles.
Two different types of CANs used by on-highway trucks, buses,
and highway equipment are - ANSWER The SAE network
standards of J-1939 and j-1587/1708.
In serial communication, one wire, called CAN-HI, has a more -
ANSWER Positive voltage than the other, which is CAN-LO. Each
wire has a mirror opposite charge of the other when
communication takes place.
