Abstract: A control apparatus for a hybrid vehicle that includes a battery includes a controller that controls a charge amount of the battery. The controller limits the charge amount of the battery at a time of low vehicle speed even when a state of charge of the battery has fallen. The controller relaxes a limitation on the charge amount when a power driving mode, in which higher priority is given to responsiveness of a driving force than at a time of a normal driving mode, is selected as a driving mode of the hybrid vehicle.

Abstract: Provided is a control device of a hybrid vehicle having an engine and a motor as driving force sources for running and configured to inform a driver that the vehicle is in motor running where the vehicle runs using only the motor as the driving force source for running, by turning on an indicator lamp, from the start of an engine rotation stop process preceding the motor running, wherein in a predetermined low vehicle speed range previously defined as a vehicle speed range where the driver is sensitive to a vehicle vibration due to passage of an engine speed through an engine resonance band, turning on of the indicator lamp is delayed from the start of the engine rotation stop process.

Abstract: An operating state display device for a vehicle includes a display portion that displays an energy transmission state of the vehicle. A display similar to what is shown when no energy is being transmitted to the axle is shown, regardless of the energy transmission state, when two conditions that the vehicle is stopped and that a brake operation is being performed are satisfied.

Abstract: An ECU for controlling an engine counts an unused time TIM of engine in a low-temperature environment. If the unused time TIM is shorter than a predetermined reference value, the ECU sets idle speed immediately after start of operation of the engine to a first idle speed, and if the unused time TIM is longer than the reference value, sets the idle speed to a second idle speed higher than the first idle speed. If duration of the second idle speed exceeds a reference period determined by state of driving of the vehicle, the ECU sets the idle speed to be lower than the second idle speed. In this manner, increased vibration in idling operation in a low-temperature environment can be prevented.
