摘要： Techniques for a mild hybrid vehicle utilize a control system for detecting a deceleration fuel shutoff (DFSO) event where fueling to an engine is disabled and in response to detecting the DFSO event: determining a desired pumping loss for the engine based on a parameter of a battery system, the desired pumping loss corresponding to a desired amount of electrical energy that a motor generator unit (MGU) of a belt-driven starter generator (BSG) system will generate to charge the battery system; commanding a throttle valve of the engine to an initial position determined based on the desired engine pumping loss and a speed of the engine; estimating an actual pumping loss of the engine based on an estimated airflow into the engine; and adjusting the position of the throttle valve based on a difference between the desired and actual engine pumping losses.

摘要： A fail safe device of an engine includes: a temperature setting module; a torque estimation module; and a torque monitoring module. The temperature setting module sets a value of a predetermined temperature parameter used in an estimation of a generation torque of the engine. The torque estimation module estimates the generation torque of the engine by using a set value of the predetermined temperature parameter set by the temperature setting module. The torque monitoring module decreases the generation torque of the engine, when the generation torque estimated by the torque estimation module is larger than a driver expected torque by a predetermined value or more.

摘要： A programmable processor receives engine speed data for an engine. The programmable processor calculates a work corresponding to a component of the engine. The calculated work is based on a change in the engine speed data over a range. A predicted work value is read from a table based on an engine speed and first metric. A value is transmitted to a control system when the calculated work is not the predicted work value. The value, when implemented by the control system, reduces a difference between the predicted work value and the calculated work for the component.

摘要： An accessory load control system for a vehicle, includes an actuator control module, a period estimation module, and a load control module. The actuator control module operates an internal combustion engine of the vehicle in a high-efficiency (HE) mode. The period estimation module estimates a period between a current time and a future time when an actual load on a crankshaft of the engine will reach a maximum engine load associated with the HE mode. The load control module selectively decreases engine loads applied by vehicle accessories, respectively, based on the period.
