    摘要： A method for continuously predicting the type of traffic in which a vehicle is traveling. The traffic pattern can be used in other vehicle control systems as an input to determine how to adjust system parameters, such as control loop proportional and integral gain calibrations. Vehicle speed is sampled over a variable number of sampling intervals, defining a prediction period. The prediction period varies as a function of distance traveled, and is limited for conditions where the distance interval is not reached within a particular time interval. When the prediction period is reached, average vehicle speed and speed variation over the period are determined. A lookup table incorporating average speed and speed variation is used to determine the traffic pattern. The prediction period can be shortened to quickly recognize transitions from city or highway traffic pattern.

    摘要： A method of controlling a deceleration rate of a hybrid electric vehicle (HEV) includes measuring an applied regenerative braking torque (RBT) during a threshold regenerative braking event (RBE), and automatically applying an offsetting friction braking torque (OFBT) from a hydraulic braking system during the threshold RBE to provide the vehicle with a substantially constant deceleration rate. An HEV having a regenerative braking capability includes a friction braking system adapted to selectively apply an OFBT to slow the HEV in one manner, an energy storage system (ESS), an electric motor/generator, and a controller having a braking control algorithm or method. The method anticipates an impending let up in the RBT based on a plurality of vehicle performance values including a threshold vehicle speed, and selectively activates the friction braking system to apply the OFBT when the impending let up in the RBT is greater than a threshold.

    摘要： A temperature control system for a vehicle comprises a coolant comparison module, a component comparison module, and a cooling fan control module. The coolant comparison module generates a coolant status signal having a first state when a coolant temperature is greater than a first threshold. The component comparison module generates a component status signal having a second state when an electronic component temperature is greater than a second threshold. The cooling fan control module selectively activates a cooling fan when at least one of the coolant status signal has the first state and the component status signal has the second state.

    摘要： An engine exhaust system includes a catalytic converter. An inlet sensor senses a first oxygen level of exhaust gases entering the catalytic converter. An outlet sensor senses a second oxygen level of exhaust gases exiting the catalytic converter. A controller communicates with a fuel system of an engine, the inlet sensor, and the outlet sensor. The controller initiates a rich condition after a fuel cut-off period and calculates a mass of oxygen released by the catalytic converter based on a mass air flow into the engine. The controller calculates a target oxygen storage capacity (OSC) of the catalytic converter over a target time period.

    摘要： Methods and apparatus are provided for projecting the useful life Yproj of an ultracapacitor undergoing at least one ON period after an OFF period. The apparatus comprises sensors coupled to the ultracapacitor for measuring the instantaneous voltage V(t) and temperature T(t) thereof as a function of time t, and a measuring system coupled to the sensors, the measuring system receiving V(t), T(t) and computing Yproj based at least in part on combining values of the instantaneous ultracapacitor life Y(V(t),T(t))=10(aT+bV+c) where a, b and c are constants, for different values of t. The measuring system preferably includes program, temporary and non-volitile memory, a processor, a timer and an I/O for communicating with the sensors and other vehicle systems. In a preferred embodiment, values of V(t), T(t) at the beginning and end of the OFF period are also used in determining Yproj.
