Controlling device and controlling method of crude oil engine accelerator

Abstract

The invention discloses a controlling device of a crude oil engine accelerator. The controlling device includes a shifting-up inching switch, a shifting-downinching switch, an engine accelerator controlling device and an engine controller. The engine accelerator controlling device includes a gear signal processing module, a special controller and a CAN bus module, wherein the gear signal processing module, the special controller and the CAN bus module are connected in sequence. The output ends of the shifting-up inching switch and the shifting-down inching switch are connected with the gear signal processing module. The gear signal processing module includes a pulse signal receiver, a photoelectric coupler and a filter. The gear signal processing module is used for converting pulse signalstransmitted from the shifting-up inching switch or the shifting-down inching switch into digital signals. The CAN bus module is connected with the engine controller. The special controller is used for extracting rotating speed values of corresponding gears according to the digital signals transmitted from the gear signal processing module and converting the rotating speed values into CAN messageinformation. The CAN message information is transmitted to the engine controller through the CAN bus module to control the engine to run at the corresponding rotating speed.

Description

technical field [0001] The invention relates to the technical field of engine control, and relates to a throttle control device for a diesel engine and a control method thereof. Background technique [0002] At present, diesel engines with EFI technology or electronic control technology are generally used in engineering equipment, and all have their own electronic control unit (Electronic Control Unit, ECU), which can control and adjust the engine speed through the CAN bus. With the popularization of CAN bus technology, and CAN bus has the advantages of less wiring, strong anti-interference, various speed control methods, and direct reading of fault codes, more and more manufacturers use throttle position sensors with CAN bus (bus throttle) Or convert the analog accelerator position sensor into a CAN bus message to send an accelerator speed command to the engine controller (E_ECU) through some device. [0003] In engineering equipment, the throttle position sensor (APS) mos...
