Abstract: An internal combustion engine (1) automatically stops when a predetermined idle stop condition is satisfied, and automatically restarts when a predetermined idle stop cancel condition is satisfied. The internal combustion engine (1) is controlled so that when fresh air does not flow into a GPF (18) even if fuel injection is stopped during operation of a vehicle, stop of the fuel injection is permitted even when temperature of GPF (18) is high. That is, the internal combustion engine (1) is controlled so that the stop of the fuel injection is forbidden when the temperature of the GPF (18) is higher than a predetermined temperature T1 and the stop of the fuel injection is allowed when the vehicle stops in a state in which the temperature of the GPF (18) is higher than the predetermined temperature (T1).

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: A first output limit value is determined as an intersection point of a knock-limit output line which is set according to an exhaust gas recirculation rate and ignition timing and an exhaust-temperature-limit output line which is set according to the exhaust gas recirculation rate and ignition timing; a second output limit value is determined as an intersection point of the knock-limit output line and an air-quantity-limit output line which is set according to the exhaust gas recirculation rate, ignition timing and atmospheric pressure; and a third output limit value is determined as an intersection point of the knock-limit output line and a thermal-management-limit output line which is set according to the exhaust gas recirculation rate, ignition timing and vehicle running speed. A value of the exhaust gas recirculation rate at which the condition “P1≥P2 or P1≥P3” is satisfied is set as a target exhaust gas recirculation rate.

Abstract: A system and method for monitoring vehicle performance and updating engine control parameters, which provides a solution to the problem of tuning engine control parameters for a vehicle. The core components of the invention are an engine controller coupled to an interface device which communicates with a remote device. Generally speaking, the components are configured as follows: the engine controller receives signals from various sensors in a vehicle and the engine controller controls the engine based on engine control parameters and the signals from the sensors. The interface device monitors the engine control and sensor signals and transmits information to the remote device. The remote device receives the information and sends back updated engine control parameters. The interface device receives the updated engine control parameters and communicates with the engine controller to update the engine control parameters using the updated engine control parameters.

Abstract: An active purge system (APS) according to a driving state of a hybrid vehicle includes an active purge unit (APU) configured to pressurize a vaporized gas generated in a fuel tank of the hybrid vehicle and supply the pressurized vaporized gas to an intake pipe, and a control unit configured to control the APU, where the control unit gradually controls a processing amount of the vaporized gas according to the driving state of the hybrid vehicle. The processing amount of the vaporized gas is gradually controlled using the APS according to the driving state of the hybrid vehicle, particularly, a number of places at which slip occurs in a power transmission system of the hybrid vehicle so that degradation of driving ability due to the occurrence of slip is reduced.

Abstract: A system that controls a combustion engine stores network vectors in a memory that represent diverse and distinct spiking neural networks. The system decodes the network vectors and trains and evaluates the spiking neural networks. The system duplicates selected network vectors and crosses-over the duplicated network vectors that represent modified spiking neural networks. The system mutates the crossed-over duplicated network vectors by randomly modifying one or more portions of the crossing-over duplicated network vectors. The system meter exhaust gas into an intake manifold when an engine temperature exceeds a threshold, an engine load exceeds a threshold, an engine's rotation-per-minute rate exceeds a threshold, and a fuel flow exceeds a threshold. The system modifies fuel flow into an engine's combustion chamber on a cycle-to-cycle basis by the trained spiking neural network.
