Abstract
An apparatus and method for rapidly providing activity on a vehicle network bus includes a node having a bus connection to the vehicle network bus. The node includes a Rapid Response Stack loaded with the predetermined message to respond to any network bus request before the application is up and running. A true stack is loaded with real messages from the application once it is booted up and running on the node, whereupon the application subsequently responds to network bus requests using the true stack instead of the Rapid Response Stack.
Claims26
A method for a node on a vehicle network bus to rapidly provide activity thereon, the method comprising the steps of:
- defining and storing at least one predetermined message in a memory of the node;
- powering up the node of the vehicle network bus;
- filling a rapid response stack of the node with the predetermined message from the memory;
- and
- transmitting the predetermined message from the rapid response stack of the node on the vehicle network bus for other nodes to read.
A system that rapidly provides activity on a vehicle network bus, the system comprising:
- a first device coupled to the vehicle network bus;
- a second device with a node coupled to the vehicle network bus through a bus connection;
- an operating system and application that are operable on the node;
- a memory of the node, the memory with at least one predetermined message stored thereon;
- a Rapid Response Stack of the node that is loaded with the predetermined messages from the memory before the node is completely initialized, wherein the Rapid Response Stack is used to respond to any network bus request from the first device by having the Rapid Response Stack transmit a predetermined message from the Rapid Response Stack of the node on the network bus.
A node that rapidly provides activity on a vehicle network bus, the node comprising:
- a bus connection to the vehicle network bus;
- an operating system and application operable to run thereon;
- a memory with a predetermined message stored thereon;
- a Rapid Response Stack that is loaded with the predetermined message from the memory upon powering of the node, wherein the Rapid Response Stack is used to respond to any network bus request by the node transmitting the predetermined message from the Rapid Response Stack on the network bus.
