A powersports vehicle with a service-oriented architecture is provided. In example aspects, a vehicle controller connected to a CAN bus performs a discovery process to identify vehicle component controllers on the CAN bus and the capabilities thereof. Based on the discovered capabilities of the vehicle component controllers, the vehicle controller can control communication with the vehicle component controllers to implement vehicle-wide features. For example, the discovery process may enable publish / subscribe and request / response communication between the vehicle controller and the vehicle component controllers. These discovery and communication processes allow for a service-oriented architecture to be implemented over the CAN bus.

A system comprising databases, database processors, a job ingestion processor, and a processor. The databases store job information for previously performed jobs. Each previously performed job comprises timestamp, job name, and amount of memory used information. The database processors detect changes to job information of the previously performed jobs and, in response, communicate the job information associated with the affected jobs to a job ingestion processor. The job ingestion processor parses the job information into timestamp, job name, and amount of memory used variables for each affected job. The parsed job information comprises timestamp values, job name values, and amount of memory used values. The processor stores the job information variables in a data log. The processor uses the job information variables to train a machine learning algorithm and the trained machine learning model to predict amounts of temporary memory needed to execute job requests.

A method for a secure in-vehicle service oriented architecture with a MAC Generate Allow List includes receiving, at a secure environment, a request to transmit a message from a device. The request to transmit includes a request for a message authentication code. The method also includes determining, based on the request to transmit, an identity of the device, and determining, based on a message authentication generate allow list, that the request to transmit does not exceed a permission level of the device. Here, the permission level of the device is stored in the message authentication generate allow list. The method also includes obtaining a secure environment key assigned to the device, the secure environment key only accessible by the secure environment, and generating the message authentication code using the secure environment key assigned to the device.
