Abstract

The invention discloses a bus throttle and a control method thereof. The bus throttle comprises an electronic throttle, an engine ECU, a main controller and a wireless remote-control device, wherein the CAN line of the engine ECU, the CAN line of the main controller, and the CAN line of the wireless remote-control device are connected in parallel to a CAN 1939 bus, and an engine controller and the main controller perform signal communications through the CAN bus; after converted by a U / I isolation amplifier, the output signals of the electronic throttle enter the main controller. The invention further discloses a control method based on the bus throttle. According to the control method disclosed by the invention, the electronic throttle of analog quantity is converted into the bus throttle, under the conditions that the wireless remote-control device is adopted and any engine is configured, the electronic throttle and the wireless throttle can respectively and normally work.

Description

technical field [0001] The invention relates to an accelerator, in particular to a bus accelerator and a control method thereof. Background technique [0002] At present, the foot accelerator used on the crane is generally an electronic accelerator, and the position of the accelerator pedal is monitored at any time through the displacement sensor inside the accelerator pedal. When the operator needs to accelerate and step on the accelerator, the pedal position sensor converts the sensed signal into an analog voltage signal of 0-5V, and transmits the signal to the engine ECU through the cable. After judgment and processing, the ECU sends instructions to the drive motor, and the drive motor drives the throttle actuator to control the engine speed. The data bus is responsible for the communication between the engine ECU and the system controller. [0003] In order to achieve remote control in complex environments, crane equipment began to use wireless remote control systems. ...
