Control apparatus for hybrid vehicle

Abstract

A control apparatus for a hybrid vehicle which increases electric power supply to a power storage unit to reduce the discharge amount from the power storage unit in the case where electric power consumption of the low voltage system is increased. There are provided: a vehicle speed sensor, an engine speed sensor, a FIECU for computing the electric power consumption of a low voltage system such as a low voltage power storage unit and engine accessories, a high electric power consumption determining device for determining whether a situation where the low voltage system electric power consumption exceeds a predetermined value has continued for a certain duration, a regeneration amount increasing device for, in the case where the vehicle speed is within a predetermined range, and the engine speed is greater than a predetermined speed, increasing the regeneration amount by the motor depending on the low voltage system electric power consumption, a generation amount increasing device for increasing the generation amount by the motor depending on low voltage system electric power consumption, and a determination threshold value correcting device for, in the case where it is determined by the high electric power consumption determining device that a situation where the low voltage system electric power consumption is above a predetermined value has continued for a certain duration, raising the determination threshold value which is the basis of approval or denial of output assistance depending on the low voltage system electric power consumption.
