A method for reinforcing safety of a vehicle on a ramp applied to a vehicle is performed by a first priority anti-skid countermeasure control in which a brake is operated together with displaying an occurrence of the skid of a vehicle/vehicle stop message on a ramp by a controller when the vehicle starts, a second priority anti-skid countermeasure control in which compensating an idle torque is performed together with displaying a guidance of anti-skid function operation/vehicle stop message is performed, a third priority anti-skid countermeasure control in which displaying a turn-off/vehicle stop message is performed, and a fourth priority anti-skid countermeasure control in which forcibly shifting to a N (neutral) stage or permitting the shift together with displaying a forcibly switching to the shift stage N stage/vehicle stop message is performed.

Vehicle designers are largely walking away from internal-combustion engines to battery and electric motors. Until infrastructure is developed to support total electrification, hybrid-electric vehicles (HEVs) which include both an internal combustion engine and an electric machine are a step toward electrification and higher system fuel efficiency while retaining the expected vehicle range. To obtain even higher system fuel efficiency combustion modes that provide higher efficiency than spark-ignition (SI) operation can be used in HEVs. A problem with such combustion modes is that they cannot be used over as wide an operating range as SI operation and transitions among modes is slow and cumbersome. By having the ICE installed into a HEV be a multi-combustion mode engine and having the EM to coordinate mode switches to be smooth, the high fuel-efficiency of alternative combustion modes can be exploited while providing smooth operation expected by vehicle users.

A system includes a generator and an engine coupled to the generator. The engine is configured to provide mechanical power to the generator. The system further includes a controller coupled to the engine and the generator. The controller is configured to: receive information regarding an engine operating parameter threshold value at which an engine operating parameter value failed to match a load demand value that is indicative of a load exerted by the generator on the engine, and set the engine operating parameter threshold value as a maximum allowable engine operating parameter value for the engine.

A method for setting an idling speed of an internal combustion engine of a motor vehicle, in which the idling speed of the internal combustion engine is increased if a predetermined power request within an on-board power system of the motor vehicle is detected, wherein a generator for electrically supplying the on-board power system is driven by the internal combustion engine, and wherein the internal combustion engine is connected to a transmission of the motor vehicle, wherein the connection between the internal combustion engine and the transmission is disconnected, and/or a predetermined braking force is made available by means of at least one brake of the motor vehicle if the predetermined power request is detected.

Since a supercharging pressure from a supercharger decreases when an actual rotation speed difference is equal to or less than a margin rotation speed difference, a response delay of an engine torque due to a response delay of the supercharging pressure in a high rotation curbing control unit can be appropriately curbed. A shortage of the engine torque with respect to a required engine torque due to a decrease in the supercharging pressure by a supercharging pressure decreasing unit is compensated for using an torque of a second rotary machine. Accordingly, it is possible to curb a decrease in power performance due to a decrease in the supercharging pressure and to prevent an engine rotation speed from falling into a high-rotation state in which the engine rotation speed exceeds a maximum rotation speed.

A mobile machine control method includes receiving, by a single controller, a first request for movement of the machine by a ground-engaging device, receiving, by the single controller, a second request for movement of an implement system of the machine, and determining, with the single controller, an amount of desired power from an engine to satisfy the first request and the second request. The method also includes selecting an engine speed from a plurality of candidate engine speeds to produce the desired power and operating the engine at the selected engine speed to produce the desired power.

A control device of a vehicle configured to travel on a plurality of travel modes includes an internal combustion engine control unit and a travel mode control unit. When a difference between a rotation speed of an internal combustion at a time when a transition condition is satisfied and a predicted rotation speed is equal to or larger than a threshold value, the internal combustion engine control unit performs rotation speed control such that the rotation speed of the internal combustion engine approaches the predicted rotation speed, and the travel mode control unit shifts a travel mode to a second travel mode after the rotation speed control of the internal combustion engine control unit is completed. The rotation speed control is control in which the rotation speed is changed in a plurality of stages so as to approach the predicted rotation speed.

A control device of a vehicle includes: a travel mode control unit configured to set, based on a traveling state of the vehicle, any travel mode among a plurality of travel modes; and a predicted rotation speed acquisition unit configured to acquire, when a transition condition to a second travel mode is satisfied based on the traveling state of the vehicle that is travelling in a first travel mode, a predicted rotation speed of the internal combustion engine when the travel mode is shifted to the second travel mode at a time when the transition condition is satisfied. The travel mode control unit includes a transition prohibition setting unit configured to prohibit transition to the second travel mode when a difference between a rotation speed of the internal combustion engine when the transition condition is satisfied and the predicted rotation speed is equal to or larger than a threshold value.

Systems and methods of controlling operation of a diesel engine using feedforward load anticipation. An electronic controller determines a difference between an actual engine speed value of the diesel engine and a desired engine speed value, and generates a feedback control command based on the determined difference. In response to detecting one or more conditions indicative of an anticipated mechanical load event that will alter a total mechanical load of the diesel engine, the electronic controller applies a feedforward offset to the feedback control command in accordance with a feedback offset function. The feedback offset function causes the magnitude of the feedback offset to decrease over a period of time until the offset returns to zero (i.e., a signal decay function). The diesel engine is then operated based on the feedback control command and the feedforward offset.
