摘要： A system and method for controlling engine idle stop in a hybrid vehicle that uses predictive information to schedule engine stops with relatively longer stop duration time to gain more fuel savings and extend life of starter motor. More specifically, predictive information may be used to determine potential vehicle stop events, along with corresponding stop duration times, within a time window. An engine stop scheduler and/or controller may be configured to schedule stops of longer duration for optimal total engine stop time. Similarly, taking into account constraints imposed by the thermal limits of the motor, engine stop may be inhibited for predicted short events to allow engine stop at later longer stop events.

摘要： A controlled engine shutdown method is disclosed that includes monitoring exhaust system temperature, monitoring operator shutdown commands, and delaying engine shutdown based on exhaust system temperature. The method can include inhibiting any process that affects exhaust temperatures, for example DPF regeneration. The method can use a shutdown timer, allow operator override of the shutdown delay, and display a delay notification message. The method can also include predicting when an engine shutdown is expected, and delaying or aborting any process that would affect exhaust temperatures when an engine shutdown is predicted. Predicting can include monitoring various machine states, determining an average activity interval for the machine, determining a geographic shutdown area, determining a shutdown time of day and/or monitoring a machine fluid level.

摘要： An automated method for diagnosing an EGHR having a coolant path, an exhaust path, a heat exchanger, and a valve. The coolant path passes through the heat exchanger and the valve selectively directs the exhaust path through the heat exchanger. The method includes monitoring an inlet temperature and an outlet temperature of the coolant path, determining an instantaneous coolant power from the monitored inlet temperature and outlet temperature, and integrating the instantaneous coolant power to determine a total energy recovered by the coolant path. The method monitors an instantaneous exhaust power, determines an instantaneous available EGHR power from the instantaneous exhaust power, and integrates the instantaneous available EGHR power to determine a nominal EGHR energy. A differential is calculated between the nominal EGHR energy and the total energy recovered by the coolant path. If the calculated differential is greater than an allowable tolerance, an EGHR error signal is sent.

摘要： A difference module determines a difference between an engine speed and a transmission input shaft speed. A state control module sets a signal to a first state when a driver releases an accelerator pedal and selectively transitions the signal from the first state to a second state when the difference is less than zero. An immediate torque request module decreases an engine torque request when the signal is in the first state and selectively increases the engine torque request when the signal is in the second state. At least one of: a spark control module that selectively adjusts spark timing based on the engine torque request; and a fuel control module that selectively adjusts fueling based on the engine torque request.

摘要： A combustion control system includes: a memory section having stored therein each control data corresponding to each of the models; a switch input section designating setting contents of each model, the setting contents being set for each of the setting items relating to the operation by switched-on/switched-off state of each switch; and an instruction section which instructs the combustion control based on control. The switch input section is provided with at least two groups each being made up of a plurality of switches. An abnormality distinguishing section is provided to distinguish whether on-off states of one group of switches and on-off states of the other group of switches coincide with each other. When the on-off states are distinguished not to coincide with each other, an instruction is given to stop the combustion control. Incomplete combustion is thus prevented even at the time of failure or wrong operation of switches.
