Abstract

The invention discloses an automatic transmission gear selecting device which comprises a man-machine interaction module and an information processing module. The man-machine interaction module is connected with the information processing module, is used for acquiring transmission operation control information of a driver and feeding the information back to the information processing module and is also used for displaying the current gear state of the transmission; the information processing module is connected with a CAN bus of a vehicle and is used for acquiring the information of the man-machine interaction module and feeding the information back to the CAN bus; the CAN bus carries information transmitted by the man-machine interaction module in the next message; after receiving the information transmitted by the man-machine interaction module, a transmission controller executes related processing; the transmission controller transmits the transmission gear information to the CAN bus in real time and controls the man-machine interaction module to output a signal capable of being indentified by the driver after the man-machine interaction module acquires the transmission gear information. The device disclosed by the invention can meet normal use of the automatic transmission and has a build-in Bluetooth transmission function of a CAN bus message.

Description

Technical field: [0001] The invention belongs to the technical field of transmissions, and in particular relates to a gear selection device of an automatic transmission. Background technique: [0002] Hydraulic automatic transmissions are widely used in special vehicles, and have a 100% utilization rate in many domestic fields, which is a potential development direction. As a device that interacts with the driver, the gear selection device is generally located in the cab. The driver can use the gear selection device to intervene in the shifting program of the automatic transmission, and can realize many additional functions. [0003] The CAN bus message data collection of commercial vehicles and buses mainly depends on the OBD2 diagnostic port of the vehicle, and the diagnostic wiring harness is used to connect the special equipment and then connect to the computer. This method is relatively expensive. Invention content: [0004] The purpose of the present invention is to...
