Abstract
Abstract A vehicle multiplex system comprises a control station (10) and a set of outstations (11 to 18) connected by individual buses (21 to 28) to the control station (10). The control station (10) and outstations (11 to 18) receive signals from local sensors and control local loads. In order to achieve a short response time at a low data transmission rate, each individual bus (21 to 28) includes a pair of data lines. One data line transmits data from the control station (10) to the associated outstation and the other data line transmits data from the outstation to the control station (10). The system is arranged so that the two data lines of each bus transmit data simultaneously. The control station (10) also includes a single bi-directional port for transmitting data over a single bi-directional data line (31) to one or more extension stations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
97 words
A vehicle multiplex system comprising a control station (10), a set of outstations (11 to 18), and an individual bus (21 to 28) for connecting each outstation (11 to 18) to the control station (10), characterised in that each individual bus (21 to 28) includes a pair of data lines (47,50;48,51;49,52), one of which transmits data from the control station (10) to the outstation and the other of which transmits data from the outstation to the control station, and the system being arranged so that, in use, the two data lines of each bus transmit data simultaneously.
Claim 2
Dependent Claim
97 words
A vehicle multiplex system comprising a control station (10), a set of outstations (11 to 18), and an individual bus (21 to 28) for connecting each outstation (11 to 18) to the control station (10), characterised in that each individual bus (21 to 28) includes a pair of data lines (47,50;48,51;49,52), one of which transmits data from the control station (10) to the outstation and the other of which transmits data from the outstation to the control station, and the system being arranged so that, in use, the two data lines of each bus transmit data simultaneously.
Claim 3
Dependent Claim
46 words
A vehicle multiplex system as claimed in claim 1, characterised in that the control station (10) is arranged to transmit data to the outstations in a format in which, during data transmission, the logical state of the line changes at the end of the clock period.
Claim 4
Dependent Claim
46 words
A vehicle multiplex system as claimed in claim 2, characterised in that each outstation is arranged to transmit data to the control station (10) in a format in which, during each clock period, the logical state of the line defines the signal which is being transmitted.
Claim 5
Dependent Claim
41 words
A vehicle multiplex system as claimed in any one of the preceding claims characterised in that the system further includes a single bi-directional port (78) for transmitting data to, and receiving data from, one or more extension stations (32, 71, 72)
Claim 6
Dependent Claim
71 words
A vehicle multiplex system as claimed in any one of the preceding claims characterised in that the system includes a set of first power supply lines (44, 44a, 44b) each of which transmits power from the control station (10) to the logic circuitry of an associated outstation (11 to 18), and at least one second power supply line (41,42) providing power for loads controlled by an associated outstation (11 to 18).
Claim 7
Dependent Claim
53 words
A vehicle multiplex system as claimed in any one of the preceding claims, characterised in that the system includes at least one device (46) operated by a vehicle driver or a vehicle passenger for connecting one of said first power supply lines (44, 44a, 44b) to an associated second power supply line (41,42).
Claim 8
Dependent Claim
64 words
A vehicle multiplex system comrising a control station (10), a set of outstations (11 to 18), and an individual data bus (21 to 28) for connecting the control station (10) to each outstation (21 to 28), characterised in that the control station (10) has a single bi-directional port (78) for transmitting data to, and receiving data from, one or more extension stations (32, 71,72).
Claim 9
Dependent Claim
64 words
A vehicle multiplex system comrising a control station (10), a set of outstations (11 to 18), and an individual data bus (21 to 28) for connecting the control station (10) to each outstation (21 to 28), characterised in that the control station (10) has a single bi-directional port (78) for transmitting data to, and receiving data from, one or more extension stations (32, 71,72).
