摘要： A method of preventing undesirable vehicle behavior in a vehicle torque control system that includes determining an expected axle torque based on a vehicle speed, a powerplant profile, an accelerator pedal position and/or a cruise control signal. The method also includes estimating an actual axle torque of a powerplant based on a powerplant maximum torque, a throttle position and powertrain inefficiencies and converting the expected axle torque to an expected acceleration and the actual axle torque to an actual acceleration based on a wheel radius and a road load. The method further includes regulating a torque output of a powerplant when a rate-of-change in a difference between the expected acceleration and the estimated actual acceleration is greater than a first threshold.

摘要： A method of verifying the integrity of an arithmetic logic unit (ALU) of a control module includes inputting a first test value into one of a plurality of registers of the ALU and inputting a second test value into remaining registers of the plurality of registers. A first set of operations is performed between the one of the plurality of registers and each of the remaining registers to produce a first set of results. A fault is indicated when one of the first set of results varies from a first predetermined result.

摘要： A vehicle having a system for validating a variable signal for input to a processor-performed function. An input module receives the signal. A processor tests first and second storage locations of a memory. After testing, the processor stores the signal in the first and second storage locations to obtain first and second stored values. The processor compares the first and second stored values and tests the first stored value for any corruption associated with receipt of the signal by said input module. The processor inputs the first and second stored values to first and second paths for performing the function to obtain two function results, and compares the results.
