    摘要： A vehicle and a vehicle system are provided with a controller that is configured to generate output indicative of a kinematic road gradient estimation using an extended Kalman filter. The extended Kalman filter includes a system input based on a longitudinal acceleration and an acceleration offset, and a system output based on a predicted vehicle speed. The acceleration offset is based on at least one of a lateral velocity, a lateral offset, and a vehicle pitch angle. The controller is further configured to generate output indicative of a kinematic quality factor corresponding to an availability of the kinematic road gradient estimation.

    摘要： A vehicle includes an engine configured for automatic shutdown and restart. The vehicle is provided with a controller that is configured to restart the engine when a difference between an actual brake pressure and a filtered brake pressure is greater than a threshold value. The filtered brake pressure is dependent upon a magnitude of the actual brake pressure and a rate of change of the actual brake pressure.

    摘要： A vehicle is provided with an engine that is configured for automatic shutdown and restart. The vehicle is also provided with a controller that is configured to shutdown the engine in response to brake effort exceeding a first threshold and to restart the engine in response to brake effort decreasing below a second threshold. The first threshold and the second threshold are based on an estimated vehicle mass and a road gradient.

    摘要： A sensing method and system for generating an output signal indicative of an estimated mean value of an input signal is provided. A sensor samples the input signal for N (N=2, 4, 8, 16, . . . ) input signal samples and determines a current twice mean value of the N input signal samples. The current twice mean value is equal to one-half of the summation of two terms, the first being twice the mean value of the first N/2 input signal samples (called the previous twice mean value) and the second being twice the mean value of the last N/2 input signal samples. The sensor then compares the current twice mean value to a previous twice mean value. The sensor then stores the current twice mean value as the previous twice mean value, increments N by a power of two, samples the input signal sample for the next N/2 input signal samples, determines the current twice mean value of the incremented N input signal samples, and compares the current twice mean value to the previous twice mean value until the current twice mean value is within a predetermined tolerance of the previous twice mean value a consecutive number of times. The sensor then generates an output signal indicative of an estimate of the mean value of the input signal. The estimated mean value is one-half of the current twice mean value.

    摘要： Methods and systems are provided for controlling the automatic shutdown of an idling vehicle engine. When the vehicle is parked in an enclosed space, the idling engine may be automatically shutdown, while when the vehicle is parked in an open space, the automatic shutdown may be delayed based on an ambient temperature. In this way, the vehicle cabin may be maintained at a temperature that provides enhanced driver comfort while allowing wasteful engine idling to be reduced.
