Open publisher page 1 citations

Abstract

Aiming at the problem about CVT automotive on long downhill,engine brake was used to control automotive velocity.At the diverse engine speed,the engine brake torque was obtained by test.The engine brake capacity was analyzed on the change of road gradient and speed ratio.On the basis,the PID controller was designed to control automotive velocity on long downhill.The results show that the control system designed can control automotive velocity with definite response speed at the less gradient,and it helps automotive brake at the biggish gradient.
