摘要： A control system for a hybrid vehicle configured to start an engine promptly during propulsion in an electric vehicle mode. Electric power generation resulting from cranking the engine by a first motor is greater in the first electric vehicle mode compared to a second electric vehicle mode. A controller that is configured to determines whether an acceptable input power to an electric storage unit is smaller than a threshold value. If the acceptable input power to the electric storage unit is smaller than the threshold value, selection of the first electric vehicle mode is inhibited.

摘要： A power-supply control device includes: a distribution adjustment unit adjusting electric energy; and a loss comparison unit comparing losses in power running and regeneration and determining, with respect to power running and regeneration, whether a loss in a current state is smaller. Further, the distribution adjustment unit adjusts the electric energy by performing the distribution in accordance with the remaining capacity ratio in the current state in a case where it is determined that the loss in power running is smaller when the current state is a power running state or in a case where it is determined that the loss in regeneration is smaller when the current state is a regeneration state.

摘要： A diagnostic system for an internal combustion engine is disclosed. The diagnostic system may include an electronic control unit. The electronic control unit may determine whether a predetermined condition is satisfied. The predetermined condition may be a condition under which an amount of particulate matter that separates from a filter is larger than or equal to a predetermined separation amount as a urea water-originated deposit once accumulated in the filter separates in gaseous form. When the electronic control unit determines that the predetermined condition is satisfied, the electronic control unit may not execute a diagnosis of a malfunction in the filter based on a filter differential pressure until a predetermined period elapses from the point in time at which it is determined that the predetermined condition is satisfied.

摘要： When individually controlling a plurality of supply valves is not available, an object of the invention is to determine which of the plurality of supply valves is abnormal with high accuracy, while suppressing a cost increase. A first supply valve, a first selective reduction NOx catalyst, a second supply valve, a second selective reduction NOx catalyst and a NOx sensor are sequentially provided in an exhaust conduit. With a view to identifying which of abnormality of the first supply valve and abnormality of the second supply valve, an instruction is given to the first supply valve and the second supply valve to increase a supply amount of a reducing agent. This identification is based on a NOx concentration detected by the NOx sensor after elapse of a first specified time duration since an instruction time point that is a time point when this instruction is given.

摘要： In a failure determination system that performs failure determination of an exhaust gas purification apparatus having a NOx selective catalytic reduction catalyst (NOx catalyst) that is disposed in an exhaust passage of an internal combustion engine and uses ammonia as a reducing agent, the failure determination of the exhaust gas purification apparatus is performed by a failure determination unit, based on a detected value of a NOx sensor that detects NOx in exhaust gas. Then, based on an adsorption amount difference at assumed failure that is the difference between an ammonia equilibrium adsorption amount in the NOx catalyst in an equilibrium state of ammonia adsorption, assuming that the exhaust gas purification apparatus is in a predefined failure state, and an actual ammonia adsorption amount in the NOx catalyst, the failure determination itself by the failure determination unit is inhibited or the use of the NOx sensor in the failure determination is restricted. Accordingly, in the failure determination system of exhaust gas purification apparatus having the NOx selective catalytic reduction catalyst, erroneous determinations at the time of failure determination are suppressed, thereby further improving the accuracy of the failure determination.

摘要： A hybrid vehicle includes a generator, a driving motor, and a battery. The control system includes the hybrid vehicle, and a controller for controlling the generator and the driving motor. The controller calculates a battery output request value and a power-generating output request value based on traveling conditions of the vehicle, and controls the driving motor and the power generator based on these values. At this time, when a state of the battery is a state in which the power-generating output request value is not satisfied, the controller executes an adjustment process for adjusting the battery output request value and the power-generating output request value. In the adjustment process, the smaller the remaining capacity of the battery, the smaller the battery output request value is and the larger the power-generating output request value is.

摘要： The invention provides a technique for more accurately executing failure diagnosis for an exhaust gas control apparatus having both a selective reduction function and a filter function. To this end, a failure diagnosis apparatus according to the invention for the exhaust gas control apparatus having both the selective reduction function and the filter function computes a NOx purification rate pertaining to a case where the exhaust gas control apparatus is normal based on an estimated value of the amount of particulate matter (PM) collected or accumulated in the exhaust gas control apparatus and an estimated value of the NO2 ratio of exhaust gas flowing into the exhaust gas control apparatus, and determines that the exhaust gas control apparatus fails when the difference between the result of the calculation and an actual NOx purification rate exceeds a threshold.

摘要： A device is provided, which makes it possible to perform a failure diagnostics for a filter more accurately even in the case of an internal combustion engine which is constructed to be capable of using both of gaseous fuel and liquid fuel. The device of the invention comprises judging means which judges any failure of the filter by comparing the added-up amount of the particulate matter contained in the exhaust gas as detected by a PM amount detecting sensor during a predetermined period and the added-up amount of the particulate matter contained in the exhaust gas as estimated by PM amount estimating means during the predetermined period, wherein the PM amount estimating means estimates the added-up amount of the particulate matter contained in the exhaust gas on the basis of the predetermined parameter and only a fuel injection amount of the liquid fuel out of a fuel injection amount of the gaseous fuel and the fuel injection amount of the liquid fuel.

摘要： An amount of reducing agent adsorbed on a NOx catalyst when a reducing agent supply device is normal and a corresponding detected value may be estimated. The corresponding detected value may be detected by a NOx sensor, and the detected value may correspond to an amount of reducing agent adsorbed on the NOx catalyst. When the estimated amount of adsorption is larger than or equal to a first amount and is smaller than or equal to a second amount, a diagnosis of the NOx catalyst based on the detected value of the NOx sensor may be prevented. The first amount may be an amount of adsorbed reducing agent corresponding to a minimum value of the corresponding detected value. The second amount may be an amount of adsorbed reducing agent corresponding to the corresponding detected value when the amount of adsorbed reducing agent is zero and larger than the first amount.
