Embodiment approach

[0014] The pressure sensor is installed at the outlet of the compressor to directly sense the pressure in the intake manifold after the action of the compressor turbine; as an electronically controlled actuator for control execution, the position sensor, control unit, motor control drive control unit, and worm drive mechanism are integrated Together, packaged in a protective shell, which can effectively shield external electromagnetic interference, form a reliable protection and prevent foreign objects from colliding and dust pollution;

[0015] The position sensor adopts the Hall principle, works in a non-contact manner, and has a long working life. After assembly, it is compensated and calibrated by online programming, which can avoid deviations caused by assembly. Precise detection of position;

[0016] Work process of the present invention is:

[0017] After the car is ignited and started, the ECU in this control system is powered on and reset. After the ECU is reset, it ...

Abstract

The invention discloses an intelligent, quick and accurate electric control system for turbo-charging adjustment. An electric control unit (ECU) which is arranged in an electric control actuator is used for performing comparison operation on a pressure signal transmitted by a pressure sensor with a guide vane position signal transmitted by a position sensor, performing prediction according to a front-three-point difference method according to a pressure value under a current state to realize deviation comparison between a guide vane position corresponding to a pressure value under the next step length target point and a pressure value under a current target position, and giving an instruction to a motor control driving unit according to an inlet pressure maximization rule after the comparison operation, so that the forward and reverse rotation or retaining motion of a motor is realized, and a turbine guide vane and a turbine rotor are in an optimally matched state. Compared with a MAP control criterion determined according to a theoretic method or a test method, a control program criterion has the advantage that errors caused by the manufacturing deviation of a gas compressor impeller, a turbine impeller, a supporting shaft system of a rotor and the like are avoided.

Description

technical field [0001] The invention is applied to the control system of the variable nozzle turbocharger of the gasoline engine and the diesel engine. The device controls and adjusts the installation angle of the turbocharger intake guide vane according to the working state of the engine, so as to reduce the fuel consumption rate of the engine and reduce harmful substances such as CO, HC and NOx in automobile emissions. [0002] Background technique [0003] With the country's requirements for reducing the fuel consumption rate of engines and the increasingly stringent emission regulations, installing turbochargers on engines has become one of the main technical means for the automotive industry to achieve this goal. A core technology that must be mastered in market competition. [0004] In the initial stage of turbocharger technology, its control part mainly adopts mechanical pneumatic bellows control device. But its control state is relatively rough, and there is a sho...
