Patent number: 11729019Abstract: Methods and apparatus are provided for periodic message transmission. Transmission of messages by the apparatus onto a communication bus are enabled during time ticks. The time ticks are separated by tick time intervals. A plurality of periodic messages configured to be transmitted on the communication bus are identified. Each periodic message has a periodicity that is a multiple of the tick time interval. The periodic messages are sorted by increasing periodicities to generate a sequence of periodic messages. A zero-start-up delay is assigned to a first periodic message in the sequence. A start-up delay is generated for each periodic message in the sequence based on a previous start-up delay associated with a previous periodic message, the tick time interval, and a periodicity of that periodic message. A transmission schedule is generated for the periodic messages based on the start-up delay and the periodicity associated with each of the periodic messages.Type: GrantFiled: October 5, 2022Date of Patent: August 15, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventor: Chang Liu
