In all modes of operation where the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.

A fuel management system includes a memory and a control module. The memory stores fuel rate maps for multiple firing fractions, where: each of the firing fractions corresponds to a respective firing pattern of an engine; at least some of the firing patterns include deactivating one or more cylinders.

A method for automatic adjustment of the performance of a vehicle may include detecting at least one significant physical quantity for checking the performance of the vehicle; defining at least one pair of reference indicators correlated with that physical quantity; saving at least one value of a said reference indicator in a predetermined nominal reference condition; detecting at least one value of a said reference indicator in a real operating condition of the vehicle; comparing said nominal reference indicator and real reference indicator and, if their values are different from each other, and implementing a correction of the driving power of the vehicle to compensate for the difference ascertained.

Methods and systems of power management in a hybrid vehicle are disclosed. A control system of the hybrid vehicle obtains battery temperature and catalyst temperature. The control system determines (a) whether the battery temperature is within an optimal battery temperature range and (b) whether the catalyst temperature is within an optimal catalyst temperature range. The control system determines a power split ratio (PSR) based on the determination of (a) and (b). The control system controls the engine and the motor-generator based on the determined PSR.

An operating system for an automated vehicle includes a failure-detector and a controller. The failure-detector detects a component-failure on a host-vehicle. Examples of the component-failure include a flat-tire and engine trouble that reduces engine-power. The controller operates the host-vehicle based on a dynamic-model. The dynamic-model is varied based on the component-failure detected by the failure-detector.

Emissions management systems for engines in hybrid systems include a sensor assembly and a controller. Sensor assembly is configured to provide an activation signal in response to an engine start event and to detect emissions information, including information indicative of an engine power, a driver demanded power, a catalyst temperature, a battery state of charge, and a battery temperature. Controller communicates with sensor assembly and is configured to: receive activation signal and, in response, emissions information from sensor assembly; determine an emissions reduction mode having a threshold value for catalyst temperature and having an engine power corresponding thereto; monitor emissions information; compare catalyst temperature to threshold value; cause the engine to operate in emissions reduction mode while catalyst temperature is less than threshold value; and allow the engine to operate in a normal operation mode while catalyst temperature is greater than or equal to the threshold value.

A vehicle includes an engine, a primary axle drivably connected to the engine, and a secondary axle drivably connected to the engine by a clutch. A controller is programmed to, in response to map data indicating that the vehicle is off-road, enable an off-road transfer torque control mode in which temperatures of the clutch are compared to a lower threshold. The controller is further programmed to, in response to the temperature of the clutch exceeding the lower threshold, display a message to a driver indicative of rising temperatures of the clutch, and, in response to a temperature of the clutch exceeding an upper limit, enable a power limiting mode in which torque of the engine is limited to a predefined value.

A vehicle is operable in three modes of operation. The vehicle includes a first electromagnetic device, a second electromagnetic device electrically coupled to the first electromagnetic device, and an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy. In each of the three modes of operation, whenever the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.
