    摘要: A transmission system for a vehicle includes an automatic transmission configured to automatically change speed ratios between an input member and an output member. An indicator is configured to provide an indication of predetermined speed ratio changes to a driver inside a passenger compartment. A corresponding method is also provided. The method includes establishing a speed ratio, determining that a speed ratio change is appropriate, and generating an indication perceptible to a driver.

    摘要: A system for a parallel intake engine includes first, second, third, and fourth modules. The first module estimates a total mass air flow (MAF) into the engine based on a cross-sectional area of a throttle and a pressure ratio across the throttle. The second module estimates first and second MAFs through first and second induction paths, respectively, based on the estimated total MAF and a factor. The third module calculates first and second differences between the estimated first and second MAFs and first and second MAFs measured by first and second MAF sensors, respectively. The fourth module detects failures of the first and second MAF sensors based on the first and second differences and first and second thresholds, respectively.
