Abstract
A system which allows an aftermarket ECM to control/alter vehicle behavior by only sending special network messages when no provision for doing so was originally designed into the original equipment manufactured system.
Claims18
A system to allow an aftermarket electronic control module to alter or control an automotive vehicle response by special controller area network messages only, the system comprising:
- a) at least one microprocessor based memory;
- and
- b) at least one processor configured by the memory to perform the steps of:
- (i) receiving a first electronic control broadcast message directed to at least one receiving module;
- and
- (ii) causing a subsequent electronic control broadcast message to alter a specific data characteristic of the first electronic control broadcast message to spoof or mimic a condition that will cause the at least one receiving module to function differently than it would have under the first electronic control broadcast message.
A device to allow an aftermarket electronic control module to alter or control an automotive vehicle response only by special controller area network messages, the device comprising:
- a) at least one microprocessor based memory;
- and
- b) at least one processor configured by the memory to perform the steps of:
- (i) receiving a first electronic control broadcast message directed to at least one receiving module;
- and
- (ii) causing a subsequent electronic control broadcast message to alter a specific data characteristic of the first electronic control broadcast message to spoof or mimic a condition that will cause the at least one receiving module to function differently than it would have under the first electronic control broadcast message.
A computer-readable medium having stored thereon computer-executable instructions for configuring a processor to allow an aftermarket electronic control module to alter or control an automotive vehicle response only by special controller area network messages by performing the steps of:
- a) receiving a first electronic control broadcast message directed to at least one receiving module;
- and
- b) causing a subsequent electronic control broadcast message to alter a specific data characteristic of the first electronic control broadcast message to spoof or mimic a condition that will cause the at least one receiving module to function differently than it would have under the first electronic control broadcast message.
