Abstract:
A control system for a hybrid vehicle including driving wheels, an internal combustion engine, a drive shaft driven by said engine, a traction motor having an assisting function of driving said drive shaft by electrical energy and a regenerative function of converting kinetic energy of said drive shaft into electrical energy, a transmission arranged between (i) said driving wheels of said vehicle and (ii) said engine and said traction motor, a clutch arranged between said (i) driving wheels of said vehicle and (ii) said engine and said traction motor, and electrical storage means for supplying electrical energy to said traction motor and for storing electrical energy output from said traction motor, the control system comprising:vehicle quick deceleration-detecting means for detecting quick deceleration of said vehicle based on operating conditions of said vehicle, andtraction motor control means for carrying out said assisting function by controlling a motor output torque from said traction motor to a predetermined positive value upon detection of said quick deceleration of said vehicle by said vehicle quick deceleration-detecting means,wherein said predetermined positive value of said motor output torque from said traction motor is based on a characteristic of control of an engaging force of said clutch carried out when said quick deceleration of said vehicle is detected.
