Message transmission control systems and methods

A system for a vehicle, comprising:

• a message generation module that generates a message that is to be transmitted to a serial data bus of the vehicle once every first predetermined period;
• a timer module that increments a timer value;
• a queue manager module that resets the timer value when the message is added to a transmit queue and that, when a number of messages in the transmit queue is less than a predetermined value, selectively adds the message to the transmit queue based on:
• a first comparison of the timer value and the first predetermined period;
• and
• a second comparison of the first predetermined period and a second predetermined period;
• and
• a communication control module that selectively transmits messages from the transmit queue to the serial data bus.

A method for a vehicle, comprising:

• generating a message that is to be transmitted to a serial data bus of the vehicle once per first predetermined period;
• resetting a timer value when the message is added to a transmit queue;
• selectively adding the message to the transmit queue when:
• a number of messages in the transmit queue is less than a first predetermined value;
• the timer value is greater than the first predetermined period;
• and
• one of:
• the first predetermined period is less than a second predetermined period;
• and
• the first predetermined period is greater than the second predetermined period and the number of messages in the transmit queue is less than a second predetermined value,
• wherein the second predetermined value is less than the first predetermined value;
• and
• selectively transmitting messages from the transmit queue to the serial data bus.
