    摘要： Methods and apparatus are provided for sending an encrypted command message from a remote keyless entry device to a receiver in a motor vehicle. The method comprises defining a key generating key within the remote keyless entry device, and using that key generating key to generate a working key. The working key is transmitted from the remote keyless entry device to the receiver during a training session without transmitting the key generating key. The working key is modified each time the remote keyless entry device is placed in the training mode. After the training session, a message encrypted with the working key can be transmitted from the remote keyless entry device to the motor vehicle receiver where the encrypted message is decrypted with the working key.

    摘要： Methods and apparatus are provided for determining the duration a motor vehicle engine may operate while operator authorization is verified in response to an ignition request. In one embodiment the method includes the steps of decrementing a pre-authorization timer from a first predetermined time limit and a maximum authorization timer from a second predetermined time limit in response to the ignition request. Also upon receipt of the ignition request an authorization process is initiated. Decrementing of the pre-authorization timer is halted in response to active operation of the starter motor of the motor vehicle, and operation of the motor vehicle is inhibited if either the pre-authorization timer or the maximum authorization timer decrements to zero before completion of the authorization operation.

    摘要： A method is provided for formatting a message, with a first plurality of bits forming a data component, and a second plurality of bits forming a reserved component, for transmission in a vehicle. The method comprises the steps of calculating an initial checksum from the data component, calculating a revised checksum at least from the initial checksum, and storing the revised checksum in the reserved component. The number of bits in the reserved component is less than the number of bits in the data component.

    摘要： A vehicle control module for controlling an actuator unit in response to an input having a first processor, a first communication link coupled to the first processor, and a second processor coupled to the first processor via the first communication link. The first processor is configured to generate a first value based on the input, transmit the first value to the actuator unit, and receive a second value from the actuator unit based on a data received by the actuator unit from the first processor. The first communication link is configured to transfer the input and the second value to the second processor. The second processor is configured to determine a third value based on the input, and verify the first value based on a comparison of the second value with the third value.

    摘要： Methods and apparatus are provided for insuring that a motor vehicle is being operated by an authorized operator. The apparatus includes an electronic control unit (ECU), an engine immobilizer unit, and a shared encryption key. The ECU generates a challenge by combining the output of a pseudo-random number generator and the output of a somewhat random number generator and cycling the combined number through a linear feedback shift register. The ECU sends the challenge to the immobilizer unit where it is encrypted with the shared key and sent back to the ECU as a response. The ECU uses the same key to encrypt the challenge and compares the encrypted challenge to the response. If the response matches the encrypted challenge, engine operation is enabled.
