Throttle clutch actuator control system

Abstract

The invention provides a control system of a throttle clutch actuator. The system is used for controlling a throttle clutch actuator including an execution motor, a position detecting device, a limitprotection device, and an actuator moving member. The control system comprises a servo driver and a main control PLC; the servo driver is used for controlling the execution motor and includes a limitprotection module and a motion control module; the limit protection module is used for sending a stop command to the motion control module when the actuator moving member is in contact with the limitprotection device; and the motion control module controls the execution motor to drive the actuator moving member to stop running and controls the execution motor to drive the actuator moving member to move in an opposite direction. With the control system, integration of the throttle actuator and the clutch actuator is realized; and the integration of the system is good.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an accelerator clutch actuator control system for an engine test bench. Background technique [0002] The engine test bench is a comprehensive system for testing engine performance, reliability and durability using special testing and testing equipment. The simulation of the driver's operation is an important link in the experiment process, and the accelerator clutch actuator is the key equipment in the simulation process. The accelerator actuator controls the opening of the accelerator pedal through the accelerator mechanical cable, and the opening of the pedal determines the opening of the throttle valve, thereby adjusting the amount of fuel entering the cylinder, and finally realizing precise control of the engine output power. [0003] The existing throttle actuator control system usually includes a controller, a motor driver, an actuator motor, a position detection d...

AI Technical Summary

Problems solved by technology

[0003] The existing accelerator actuator control system usually includes a controller, a motor driver, an actuator motor, a position detection device, a limit protection device, a mechanical transmission system and a pedal connection device. Currently, there are many actuator products with high precision and high speed on the market. It is a servo motor type, but the general product has the disadvantages of bulky structure, inconvenient installation and debugging, poor versatility, small range of torque value and cannot be set, weak travel limit protection function, incremental encoder needs to start and return to zero, etc.

The poor versatility is mainly reflected in the fact that the accelerator actuator and the clutch actuator are not universal, and the controller is a dedicated controller, which is not conducive to the integration with the system
