Abstract:
By the
bond graph theory, a bond graph analysis model of continuously
variable transmission is established. On the basis of improving
the ratio change response and reducing the engine torque
response lag in normal control, a new synthetic control
algorithm is developed. By analyzing the engine driving torque
characteristics and the transmission inertia torque while ratio
is changed under transient condition, the compensation value for
engine driving torque is presented. The simulation result shows
that by this compensation control algorithm the engine torque
response lag can be reduced and the driving torque response can
be improved effectively.
