Abstract: A control system for controlling operation of an internal combustion engine is configured to: receive a first request signal indicative of first torque demand; determine a schedule defining an opening timing of the intake valve and a closing timing of the intake valve of a cylinder of the internal combustion engine in dependence on the first torque demand; and cause the intake valve to open in accordance with the schedule. The control system is also configured to, during a period in which the intake valve is open: receive a second torque request signal indicative of a second torque demand different to the first torque demand; determine an updated schedule defining an updated closing timing of the intake valve in dependence on the second torque demand; and cause the intake valve to close in accordance with the updated schedule.

Abstract: Methods and systems for operating a vehicle that includes a manual transmission are presented. In one example, a method for a vehicle having a manual transmission comprises, during an initial launch with traction control enabled, overriding driver throttle commands to maintain a setpoint speed of an engine and limiting wheel slip until wheel slip decreases below a non-zero threshold.

Abstract: A control device and method controls a vehicle having an internal combustion engine connected to an automatic transmission via a torque converter with a lockup device. The torque of the internal combustion engine is limited the by a torque limit value based on a speed difference between an input rotational speed and an output rotational speed of the torque converter during acceleration in a non-lockup state. The torque-limiting of the internal combustion engine is prohibited torque-limiting upon a prescribed condition being met. The prescribed condition is met by a heating request, during hill climbing/towing, during travel at high vehicle speeds, when the accelerator pedal opening angle exceeds or is equal to a prescribed opening angle, when the torque limit value is greater than a target torque, in a range other than a D range, or in a mode other than normal mode.

Abstract: An internal combustion engine may have an intake valve device. A sudden load variation may be carried out in which a torque provided by the internal combustion engine is increased from a first value to a second value which is higher than the first value. While the sudden load variation is being carried out, the intake valve device may be operated according to an operating method different from the second operating method and is thereby closed later than in the second operating method. After the sudden load variation has been carried out, and while the internal combustion engine provides the torque having the second value after the sudden load variation has been carried out, the internal combustion engine may be switched over from the first operating method different from the second operating method to the second operating method.

Abstract: Methods and a system are provided for shaping a torque profile for a motor of a hybrid vehicle. In one example, the method includes during a vehicle launch, an off condition of an engine, and upon receiving an engine start request, predicting a time of engine engagement, predicting a driver requested torque at the engine engagement; and reducing the driver requested torque until the predicted time of engine engagement based on the predicted driver requested torque at the engine engagement. The predicting of at least one of the time of engine engagement and the driver requested torque at the engine engagement may be based on a current position of an accelerator pedal and a driver profile. The method may further include controlling motor torque profile based on the reduced driver request torque.

Abstract: The engine controller includes storage which stores a fuel efficiency operation line for optimizing engine fuel consumption and a booming noise avoidance operation line for keeping the booming noise below a certain limit. The operation point region where the booming noise exceeding the certain limit is generated is a booming noise region. The fuel efficiency operation line passes through the booming noise region. In contrast, the booming noise avoidance operation line does not pass through the booming noise region. The controller controls the engine according to the booming noise avoidance operation line. The controller controls the engine according to the fuel efficiency operation line for a predetermined period after determining that the driver intends to change the speed of the vehicle.

Abstract: A phase diagnosis method and apparatus. When it is verified that the location of an engine is valid, an oil injector performs spraying at a top center compression position; if no acceleration is detected after spraying, it indicates that a fault occurs; in order to detect whether it is a fault of phase deviation of the camshaft by 180 degrees, the oil sprayer performs spraying at the top center exhaust position and detects whether there is an acceleration; if an acceleration is detected, it indicates that the situation of the phase deviation of the camshaft by 180 degrees exists. In this way, the problem in the prior art of being unable to detect phase deviation when the phase of a camshaft is deviated by 180 degrees is solved.

Abstract: A vehicle control system includes an accelerator sensor which detects an accelerator opening, and a processor which sets a target acceleration of a vehicle based on the detected accelerator opening, sets a target torque of a drive source based on the set target acceleration, and controls the drive source to generate the set target torque. In a case where the target acceleration at a time when the accelerator opening is increased is set as a depression-increasing target acceleration and the target acceleration at a time when the accelerator opening is decreased is set as a pedal-returning target acceleration, under the same condition of the accelerator opening, the processor sets the target acceleration such that the depression-increasing target acceleration and the pedal-returning target acceleration are different from each other in a predetermined range of an upper limit acceleration or less and a lower limit acceleration or greater.

Abstract: A controller may determine that a regeneration process associated with an engine of a machine is active. The controller may obtain, based on determining that the regeneration process is active, information concerning a speed of the engine, information concerning a load of the engine, and information concerning a fuel rate of the engine. The controller may select, based on the information concerning the speed of the engine, the information concerning the load of the engine, and the information concerning the fuel rate of the engine, a control process, of a plurality of control processes, to control an intake manifold absolute pressure (IMAP) of the engine to facilitate the regeneration process. The controller may cause, according to the selected control process, adjustment of one or more components of a variable geometry turbocharger (VGT) of the engine and an intake throttle valve (ITV) of the engine.
