Abstract

The invention relates to a motor-driven type throttle servo system. The motor-driven type throttle servo system comprises an engine speed sensor (10), an accelerator pedal position sensor (11), a motor position sensor (12), a servo system electronic control unit (13) and a motor (14), wherein the engine speed sensor (10) is used for sensing the engine speed and outputting an engine speed signal; the accelerator pedal position sensor (11) is used for sensing an accelerator pedal position and outputting an accelerator pedal position signal; the motor position sensor (12) is used for sensing the motor position and outputting a motor position signal; the servo system electronic control unit (13) is used for collecting the engine speed signal, the accelerator pedal position signal and the motor position signal; the motor (14) is used for adjusting according to a control instruction sent by the electronic control unit. According to the motor-driven type throttle servo system, the throttle servo system is designed into an independent module, and when an automatic mechanical speed change electronic control unit coordinates with an electronic control engine for work, the module does not need to be installed without influence on other functions; when the automatic mechanical speed change electronic control unit needs to coordinate with a non-electronic control engine for work, the module is installed, and the control requirement on the engine speed can be met.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a motor-driven throttle servo system. Background technique [0002] Throttle servo technology is similar to the electronic throttle technology currently used in some mid-to-high-end cars. It can be said that the basic structure of the two is the same, but the throttle servo system also needs to realize some functions of the engine electronic control unit, such as engine speed regulation. [0003] During the shifting period of the automatic mechanical transmission system, the engine speed is not controlled by the accelerator pedal, but is adjusted to the speed matching the target gear, so as to reduce clutch wear and shifting shock and ensure vehicle comfort; After the end, the engine speed needs to be softly transitioned to the speed corresponding to the accelerator pedal. This requires the engine to be able to receive the control instructions from the automatic mechanical ...
