    Abstract: A method of transmitting data within a vehicle includes: storing two copies of a data message; constructing at an electronic control unit (ECU) a serial bus message that includes one copy of the data message and a message authentication code (MAC) created using a secret key stored at the ECU, a MAC algorithm, and a different copy of the data message; transmitting the serial bus message to a receiving ECU over a vehicle bus; authenticating the serial bus message at the receiving ECU using a copy of the key stored at the receiving ECU by creating a copy of the MAC from the data message included in the serial bus message and the copy of the key; comparing the MAC from the serial bus message with the copy of the MAC created at the receiving ECU; and rejecting or accepting the data message based on the comparison.

    Abstract: Systems and methods are provided for effecting control through multi-stage voting. A control system may be in communication with an actuator device responsive to a voted command. A multi-stage voting system may be configured to determine the voted command. A set of controllers and a monitor controller may provide commands to the multi-stage voting system. The multi-stage voting system includes logic with a first stage that compares the commands of the set of controllers to each other, and a second stage that compares at least one of those commands to the monitor command. The multi-stage voting system delivers the voted command to the actuator device based on the comparisons made in the first and second stages. The actuator device effects an operation in response to the voted command.

    Abstract: A control system for an autonomous vehicle includes at least one controller. The controller is programmed to receive first sensor readings from a first group of sensors, provide a first sensor fusion output based on the first sensor readings, the first sensor fusion output including a first detected state of a detected object, receive second sensor readings from a second group of sensors, and provide a second sensor fusion output based on the second sensor readings, the second sensor fusion output including a second detected state of the detected object. The controller is additionally programmed to, in response to the first detected state being outside a predetermined range of the second detected state, generate a diagnostic signal.

    Abstract: A method applying an electric park brake system of a vehicle includes detecting a park request with a first vehicle control module, and sending a park command, from the first vehicle control module, to both an electric brake control module and a second vehicle control module. Upon the electric brake control module receiving the park command, an actuation signal is sent from the electric brake control module to a motor winding of the electric park brake system. A status actuated signal is sent from the electric brake control module to the second vehicle control module. The status actuated signal indicates that the actuation signal has been sent from the electric brake control module. A position of the motor winding is sensed to determine if the motor winding is actuated. When the motor winding is actuated, a message is displayed to indicate that the electric park brake system is applied.

    Abstract: A control system for a vehicle includes at least one controller. The controller is programmed to receive first sensor readings from a first group of sensors and provide a first vehicle pose based on the first sensor readings. The first vehicle pose includes a first location and a first orientation of the vehicle. The controller is also programmed to receive second sensor readings from a second group of sensors and provide a second vehicle pose based on the second sensor readings. The second vehicle pose includes a second location and a second orientation of the vehicle. The controller is further programmed to, in response to the first vehicle pose being outside a predetermined range of the second vehicle pose, generate a diagnostic signal.
