A control system for a hybrid vehicle includes a controller. When a downshift of a transmission and an increase in an amount of regeneration are carried out during regenerative coast traveling in which regeneration is carried out by an electric motor, and when a state of charge of a battery is lower than a predetermined value, the controller increases the amount of regeneration before completion of the downshift. When the state of charge of the battery is higher than or equal to the predetermined value, the controller increases the amount of regeneration after completion of the downshift.

Catalyst Deterioration Detecting Apparatus of Vehicle Internal Combustion Engine
InactiveUS20090030592A1Suppresses deterioration of drivabilityInternal-combustion engine testingElectrical controlOxygen sensorEngineering
A determining section integrates amount of oxygen that is stored in or released from a exhaust gas purifying catalyst from when a signal from an oxygen sensor is changed until when the signal is changed subsequently, thereby calculating an oxygen storage capacity. The determining section uses the calculated oxygen storage capacity to determine a deterioration state of the exhaust gas purifying catalyst. A limiting section sets, as an allowable change amount, a change amount of the air-fuel ratio that corresponds to an allowable maximum fluctuation amount of a torque of a output shaft of the engine. The limiting section limits a change of the target air-fuel ratio such that a change amount of the target air-fuel ratio due to a change of the signal does not exceed the allowable change amount. Therefore, a deterioration of a drivability while ensuring opportunities of detecting a deterioration of an exhaust gas purifying catalyst is suppressed.

System to control the torque of an internal combustion engine during a gear change
ActiveUS9371070B2Suppresses deterioration of drivabilityLow costElectrical controlExhaust gas recirculationAutomatic transmissionExternal combustion engine
An electronic control unit executes throttle torque reduction control for decreasing an engine torque by reducing a throttle opening degree during an upshift of an automatic transmission with respect to the throttle opening degree before a start of the upshift. During the upshift of the automatic transmission, the electronic control unit actuates a waste gate valve in a closing direction with respect to a position of the waste gate valve before the start of the upshift in parallel with execution of the throttle torque reduction control. Thus, a decrease in supercharging pressure due to execution of the throttle torque reduction control is suppressed during the upshift, and the engine torque that has been temporarily decreased in an inertia phase of the upshift recovers immediately after the upshift, so it is possible to suppress deterioration of drivability.
