    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: An automotive vehicle includes a vehicle steering system, an actuator configured to control the steering system, a first controller, and a second controller. The first controller is in communication with the actuator. The first controller is configured to communicate an actuator control signal based on a primary automated driving system control algorithm. The second controller is in communication with the actuator and with the first controller. The second controller is configured to, in response to a first predicted vehicle path based on the actuator control signal deviating from a desired route by a threshold distance, control the actuator to maintain a current actuator setting. The second controller is also configured to, in response to the first predicted vehicle path not deviating from the desired route by the threshold distance, control the actuator according to the actuator control signal.

    Abstract: A system and method of transmitting data within a vehicle over a vehicle bus includes: constructing at an electronic control unit (ECU) a serial bus message that includes a data message and a message authentication code (MAC) that is created using a secret key stored at the ECU, a MAC algorithm, and the data message; transmitting the serial bus message to a receiving ECU over the vehicle bus; and authenticating the serial bus message at the receiving ECU using a copy of the secret key stored at the receiving ECU by creating a copy of the MAC from the data message included in the serial bus message, the copy of the secret key, and the MAC algorithm; comparing the MAC included in 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 translation: 一种在车辆车辆内部传输数据的系统和方法包括：在电子控制单元（ECU）处构建包括数据消息的串行总线消息和使用存储的秘密密钥创建的消息认证码（MAC） 在ECU处，MAC算法和数据消息; 通过车辆总线将串行总线消息发送到接收ECU; 以及使用存储在接收ECU处的秘密密钥的副本，在接收ECU处验证串行总线消息，通过从包括在串行总线消息中的数据消息，秘密密钥和MAC的副本创建MAC的副本 算法; 将串行总线消息中包括的MAC与在接收ECU处创建的MAC的副本进行比较; 并基于比较拒绝或接受数据消息。
