摘要： A method for controlling torque in a hybrid powertrain system to selectively transfer mechanical power to an output member includes monitoring operator inputs to an accelerator pedal and to a brake pedal. An immediate accelerator output torque request, a predicted accelerator output torque request, an immediate brake output torque request, a predicted brake output torque request, and an axle torque response type are determined. An output torque command to the output member of the transmission is determined based upon the immediate accelerator output torque request and the immediate brake output torque request.

摘要： An exemplary method for operating a hybrid vehicle in the event that there is a problem with an auxiliary power source, such as an internal combustion engine or a fuel cell. According to one embodiment, the method provides a power management scheme for a variety of situations where an auxiliary power source experiences a problem; this may include situations where an internal combustion engine runs out of fuel, where there is a mechanical or electrical malfunction, or any other instance where the auxiliary power source is unable to generate and/or provide electrical energy for the hybrid vehicle. The power management scheme conserves the vehicle's primary power source, which is typically a battery, in order to provide the hybrid vehicle with an extended driving range.

摘要： An apparatus includes a multi-phase inverter, a fault detector to indicate a detection of a fault, a sensor to provide a speed signal indicative of whether a speed of a PM motor is greater than a transition speed, and a controller. The controller is operable to apply either an open-circuit response or a short-circuit response to the multi-phase inverter. The open-circuit response is applied when the speed of the PM motor is greater less than the transition speed and a fault is detected. The short-circuit response is applied when the speed of the PM motor is less greater than the transition speed and the fault is detected. The transition speed is either a fixed predetermined speed or an adjusted predetermined speed.

摘要： A hybrid electric vehicle (HEV) has an algorithm for executing a method for diagnosing a high-voltage (HV) fault condition aboard the HEV. The HEV includes a high-voltage (HV) battery, an auxiliary power module (APM), a power inverter module (PIM), and a three-phase motor/generator unit (MGU). A controller executes the method to thereby measure a DC output current from the HV battery, a DC inlet current into the APM, and a pair of AC phase currents in the MGU. The method further includes calculating a DC inlet current into the PIM using the AC phase currents, diagnosing the HV fault condition using the DC output currents and the DC inlet currents, and executing a control action in response to the diagnosed condition. The method can include shutting off the APM to determine whether the APM is the root cause of the HV fault condition.

摘要： The derivative of a noise-containing input signal is determined by using an aliased derivative to periodically reset a filtered version of a normally determined derivative. The aliased derivative is calculated using a slower update or sampling rate than the normally determined derivative, and the filtered version of the normally determined derivative is reset to a reset value at each update of the aliased derivative. The reset value is based on a weighted sum of the aliased derivative and the filter output. The periodically reset filter output closely follows an idealized derivative of the input signal, substantially eliminating the phase delay introduced by conventional filtering.
