Communications bridge between a vehicle information network and a remote system
First Claim
1. A communications bridge between a communications network carried by a motor vehicle and configured for communications according to a first protocol and a remote system configured for communications according to a second protocol, the communications bridge comprising:
- a first interface configured for coupling to said communications network;
a second interface configured for coupling to said remote system; and
a digital signal processor (DSP) configured to process multiple operations per instruction cycle, said DSP receiving information configured according to said first protocol from said communications network via said first interface, converting said information received from said communications network and configured according to said first protocol to said second protocol and transmitting said information converted to said second protocol to said remote system via said second interface, said DSP receiving information configured according to said second protocol from said remote system via said second interface, converting said information received from said remote system and configured according to said second protocol to said first protocol and transmitting said information converted to said first protocol to said communications network via said first interface.

Abstract
A communications bridge between a communications network carried by a motor vehicle and configured for communications according to a first protocol and a remote system configured for communications according to a second protocol, includes a first interface configured for coupling to the communications network, a second interface configured for coupling to the remote system, and a digital signal processor (DSP) configured to process multiple operations per instruction cycle The DSP receives information from the communications network via the first interface, converts this information to the second protocol and transmits the information converted to the second protocol to the remote system via the second interface. The DSP further receives information from the remote system via the second interface, converts this information to the first protocol and transmits the information converted to the first protocol to the communications network via the first interface.

62. A method of communicating information between at least one communications network carried by a motor vehicle and a remote system, said at least one communication network configured for communications according to a first protocol and the remote system configured for communications according to a third protocol, the method comprising the steps of:
-
receiving via a first interface coupled to said at least one communications network a first set of data from said at least one communications network configured according to said first protocol;
providing said first set of data received via said first interface to a digital signal processor (DSP) configured to process multiple operations per instruction cycle;
converting with said DSP said first set of data from said first protocol to said second protocol;
providing said first set of data configured according to said second protocol from said DSP to a second interface coupled to said remote system; and
transmitting to said remote system via said second interface said first data set configured according to said second protocol. - View Dependent Claims (63, 64, 65, 66, 67, 68)
