A fault detection and processing method for automatic shifting of electric tractors

Abstract

The invention discloses a fault detecting and handling method for automatic shifting of an electric tractor. A remote control unit screen, a remote control unit master chip, a transmitting unit, a receiver, a vehicle control unit (VCU), an H-bridge, an actuating mechanism electric push rod and a shift lever are comprised; the actuating mechanism electric push rod and the shift lever are connectedand a pressure sensor is arranged therebetween; the output end of the remote control unit screen is electrically connected with the input end of the remote control unit master chip; the output end ofthe remote control unit master chip is electrically connected with the input end of the transmitting unit; the output end of the transmitting unit is electrically connected with the input end of the receiver; the output end of the receiver is bidirectionally connected with the input end of the VCU; the output end of the VCU is electrically connected with the input end of the H-bridge; and the output end of the H-bridge is electrically connected with the input end of the actuating mechanism electric push rod. The fault detecting and handling method for automatic shifting of the electric tractoreffectively avoids the conditions that a fault cannot be handled in time and the shift lever is damaged during automatic shifting.

Description

technical field [0001] The invention relates to the technical field of electric tractors, in particular to a fault detection and processing method for automatic shifting of electric tractors. Background technique [0002] With the country's requirements and promotion of agricultural mechanization, farmers' requirements for agricultural machinery intelligence have increased, and the demand for agricultural machinery has also increased. The country requires vigorous development of agriculture and promotes agricultural machinery and equipment to move towards intelligence, informationization, and modernization. At present, most of the unmanned tractors in China still have cabs. However, for unmanned electric tractors without cabs, remote control is required to achieve automatic shifting. However, shifting failures often occur during the shifting process, and then As a result, the gear shifting is not in place, the gear lever is easily damaged, and the operation of the tractor is...
