Abstract

The invention is suitable for the field of automobile transmissions, and particularly relates to an AMT electronic gear shifter device. The AMT electronic gear shifter device comprises a circuit board and an operating lever mechanism capable of swinging. The circuit board and the operating lever mechanism are fixedly connected. A magnet is arranged on the operating lever mechanism. The operating lever mechanism is connected with the circuit board through the magnet. A Hall element is arranged on the circuit board. The magnet is connected with the Hall element in an induction manner. The magnet switches the induction position for the Hall element through swinging of the operating lever mechanism. The structure of the AMT electronic gear shifter device passes full vehicle reliability durability tests and power assembly reliability durability tests. Compared with AMT electronic gear shifters shaped like a Chinese character 'tu' and AMT electronic gear shifters of an 'F' structure, by means of the design scheme, 8 routes of control logic signals are achieved, MCU configuration is reduced, and cost is reduced.

Description

technical field [0001] The invention is applicable to the field of automobile gearboxes, and in particular relates to an AMT electronic shifter device. Background technique [0002] In order to improve the driving comfort and safety of the vehicle and retain the manufacturing cost advantage of the manual transmission, a shift and clutch controller is added to the manual transmission, which is derived into a new automatic transmission, referred to as AMT. AMT needs to send the driver's driving intention through the electronic shifter, and send instructions through the TCU to control the actuator on the gearbox to perform clutch and shift operations. [0003] The commonly used AMT electronic shifters on the market are of "earth" shape and "F" structure. This structure usually uses 4-way signal control logic, which is not suitable for control logic with 8-way control electrical signals. "Earth" type and "F" structure electronic shifters use Hall sensor components, and the circ...
