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： An ignition switch sensor having a plurality of contacts arranged on a sensor to make intermittent contact with a movable contact and generate a first plurality of outputs corresponding to the position of the movable contact relative to the plurality of contacts. A power mode module receives the first plurality of outputs and compares the outputs to data stored within the memory of the module and provides a second plurality outputs according to the value of the first plurality of outputs. A theft resistor may be integrated into the ignition switch sensor circuitry to facilitate protection from tampering and unauthorized starting of the vehicle's engine.

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： An exemplary transmission system includes a plurality of sensors each configured to output a signal at least partially representative of a speed of at least one of a first transmission input shaft, a second transmission input shaft, a transmission output shaft, and an engine. A transmission control module is in communication with the plurality of sensors and is configured to identify at least one of the plurality of sensors as a failed sensor and another of the plurality of sensors as a working sensor. The transmission control module is further configured to estimate the signal of the failed sensor based on a predetermined relationship between an expected signal from the failed sensor and the signal received from the working sensor.
