A control device for a vehicle includes an upper limit value setting unit configured to set an upper limit value of an acceleration or deceleration of the vehicle, and a vehicle controller configured to control the vehicle such that the acceleration or deceleration does not exceed the upper limit value. The upper limit value setting unit is configured to change the upper limit value according to at least one predetermined condition.

An engine output control device controls engine output at a time of a downshift speed change of a transmission. The engine output control device includes: engine speed detecting means for detecting an actual engine speed NeJ of a crankshaft; and engine output adjusting means capable of adjusting the engine output according to an operation of a rider. The smaller of a requested engine output PA calculated on a basis of the actual engine speed NeJ and a rider requested engine output PB adjusted by the engine output adjusting means is output as the engine output.

A method performed by a control unit in connection with a pre-heating process of an aftertreatment system for a combustion engine is provided. The control unit obtains a scheduled start time of the combustion engine. The control unit schedules a pre-heating of the aftertreatment system to be completed before the scheduled start time. The control unit detects a start of the combustion engine at an actual start time. In response to the detected start of the combustion engine, and using the actual and scheduled start times, the control unit determines whether the scheduled pre-heating of the aftertreatment system fulfils one or more success criteria. When the one or more success criteria are fulfilled, the control unit triggers a performance increase of the combustion engine.

When an accelerator pedal operation amount is large enough to generate a driving force after switching from a stopping range to a starting range is performed, in order to prevent a sudden starting immediately after the range switching, an upper limit of the driving force of a driving source is limited to a driving force larger than a holding threshold value for releasing holding of a stopping state of a vehicle and smaller than a required driving force based on the accelerator pedal operation amount.

A system and method for dynamically controlling an aggregate load on a generator is described. Fuel change data for a gaseous fuel for the generator is identified. The fuel change data indicates a change in fuel type for the generator. A controller identifies at least one load portion from the aggregate load associated with the change in fuel type and generates a switch command for a switch coupled to the at least one load in response to the change in fuel type.

A method and a system for controlling a propulsive power output applied to a propeller shaft of a ship. If a current value of a propulsive power of a propulsive power source equals or falls below a lower power limit value, and/or if a current value of an operational parameter reaches a first/lower parameter limit value, a control unit is configured to: increase a power output of an internal combustion engine of the propulsive power source. Thus, operation of the engine below a lower power limit is avoided.

A vehicle control system determines that a vehicle is not fully loaded with a payload, determines an upper limit on engine propulsion power for the vehicle that is not fully loaded with the payload, and reduces an engine speed of the vehicle to a determined speed at which a power capability of an engine of the vehicle matches the upper limit on the engine propulsion power of the vehicle.

A control system is provided for a diesel particulate filter (DPF) system of a diesel engine configured for operation in an off-highway vehicle. The control system includes a controller configured to receive a signal corresponding to a fill state of the DPF being at or above a first threshold. The controller is configured to selectively induce a parasitic load on the diesel engine to increase an operating temperature of the engine in response to receiving the signal.

A method for accelerating a vehicle from rest. The method includes receiving a mode indication indicating a launch control mode selected; receiving a brake-on indication; controlling the engine according to a launch control strategy; determining an accelerator position; for an accelerator position greater than zero, controlling the engine to: increase open a throttle valve and control the engine to limit engine torque output; receiving a brake-off indication; controlling the engine according to the standard control strategy, controlling the engine according to the standard control strategy with the braking system having been released causing the vehicle to accelerate from rest, a first rate of acceleration from rest of the vehicle being greater than a second rate of acceleration from rest of the vehicle for corresponding changes in accelerator position, the first rate corresponding to accelerating from rest after controlling the engine according to the standard and launch control strategies.

A hybrid vehicle including: an engine; output member that transmits driving force to drive wheels; a rotating electric machine; and a power split mechanism that splits and transmits the driving force output from the engine to the output member and the rotating electric machine, the mechanism including at least three rotating elements of an input element connected to the engine, a reaction force element connecting the rotating electric machine, and an output element connecting the output member, the machine capable of outputting reaction force torque to required engine torque based on an acceleration request to apply torque to the required engine torque to the drive wheel, where the machine does not output the reaction force torque, engine rotation speed increase control being able to be executed, engine torque limitation due to a NV requirement being able to be executed and which is relaxed during the engine rotation speed increase control.
