Control system for hybrid vehicles
First Claim
1. A control system for a hybrid vehicle including an internal combustion engine, a drive shaft driven by said engine, a generator for converting kinetic energy of said drive shaft to electrical energy to generate electric power, and electrical storage means for storing electrical energy output from said generator, the control system comprising:
- deceleration-detecting means for detecting deceleration of said engine;
fuel supply-interrupting means for interrupting supply of fuel to said engine during said deceleration of said engine;
intake air amount control means for controlling an amount of intake air supplied to said engine such that said amount of intake air supplied to said engine is increased when said generator regenerates electrical energy during said deceleration of said engine;
regeneration amount-calculating means for calculating an amount of electrical energy to be regenerated by said generator during said deceleration of said engine; and
output control means for controlling an output from said generator, based on said amount of electrical energy calculated by said regeneration amount-calculating means.

Abstract
A control system is provided for a hybrid vehicle including an internal combustion engine, a drive shaft driven by the engine, a generator for converting kinetic energy of the drive shaft to electrical energy to generate electric power, and an electrical storage device for storing electrical energy output from the generator. Deceleration of the engine is detected. Supply of fuel to the engine is interrupted during the deceleration of the engine. An amount of intake air supplied to the engine is controlled such that the amount of intake air supplied to the engine is increased when the generator regenerates electrical energy during the deceleration of the engine. Calculation is made of an amount of electrical energy to be regenerated by the generator during the deceleration of the engine. An output from the generator is controlled based on the amount of electrical energy calculated.
