A steering assist apparatus comprises a steering assist control means for performing a lane tracing assist control (LTA) and a lane changing assist control (LCA) and a non-holding determination means for determining whether or not a first non-holding condition that a non-holding duration time is more than or equal to a first time is satisfied and whether or not a second non-holding condition that the non-holding duration time is more than or equal to a second time shorter than the first time is satisfied. The steering assist control means raises a warning when the second non-holding condition becomes satisfied and stops the LTA when the first non-holding condition becomes satisfied while performing the LTA, and raises a waring when the second non-holding condition becomes satisfied whereas continues the LCA until a completion condition of the LCA becomes satisfied regardless of the non-holding while performing the LCA.

A vehicular control apparatus includes at least one electronic control unit. The at least one electronic control unit is configured to recognize a first preceding vehicle in a driving lane and to calculate a first target acceleration of the vehicle. The at least one electronic control unit is also configured to recognize a second preceding vehicle in an adjacent lane, and to calculate a second target acceleration of the vehicle. The at least one electronic control unit is configured to acquire lane change information of the vehicle, and to select the smaller of the first target acceleration and the second target acceleration as a target acceleration of the vehicle. The at least one electronic control unit is configured to control a speed of the vehicle in a lane change period by using the selected target acceleration.

Vehicular control apparatus

A drive assistance apparatus includes a target trajectory setting unit configured to set a target trajectory in a lane change assistance based on a movement time taken for a vehicle of which the direction indicator is continued to be in ON-state to move a lateral distance set in advance to the adjacent lane side from an operation start lateral position, and a lane change assistance unit configured to execute the lane change assistance for causing the vehicle to change lane along the target trajectory in a case where the lateral position of the vehicle of which the direction indicator is continued to be in ON-state reaches the assistance start lateral position set in advance in the travelling lane from the setting of the target trajectory by the target trajectory setting unit.

Drive assistance apparatus

An exhaust gas purification system comprises a NOx catalyst for absorbing the NOx in the exhaust gas when the air-fuel ratio of the influent exhaust gas is lean and purifying by reducing the absorbed NOx with a reducing agent in the exhaust gas when the air-fuel ratio of the exhaust gas turns rich, a first unit for calculating the amount of NOx absorbed per unit time in each area of the NOx catalyst when the air-fuel ratio of the exhaust gas flowing into the NOx catalyst is lean, and a second unit for calculating the total amount of NOx absorbed into the NOx catalyst by totaling the amounts of NOx calculated by the first calculation unit for the areas of the NOx catalyst.

Exhaust gas purification system for internal combustion engine

A catalytic emission control apparatus of an internal combustion engine that has an engine stop mode of stopping the internal combustion engine during a run of a vehicle utilizes an oxygen absorption-storage action of an emission control catalyst disposed in an exhaust passage of the internal combustion engine. The emission control apparatus has a storage computing device that computes a storage of oxygen in the emission control catalyst, and air-fuel ratio controller performs an air-fuel ratio control of the internal combustion engine based on the storage of oxygen computed by the storage computing device. The storage computing device computes the storage of oxygen during the engine stop mode of the internal combustion engine. The air-fuel ratio controller performs the air-fuel ratio control when the internal combustion engine is restarted after the engine stop mode is discontinued, based on the storage of oxygen computed by the storage computing device during the engine stop mode.
