Abstract

The invention discloses a gear two-way output structure of an electronic gear shifter. The gear two-way output structure comprises a gear shifting control mechanism, a positioning reed and a gear shifting controller circuit board. The gear shifting control mechanism is fixed to a gear shifting support, the positioning reed is fixed to the gear shifting support and movably connected with the bottomof the gear shifting control mechanism, and the controller circuit board is arranged on one side of the gear shifting control mechanism. The gear shifting handle can accurately reach the angle of thegear shifting position through the matching of a tooth-shaped groove of a gear shifting plate and the positioning reed; a Hall sensor on the gear shifting controller circuit board outputs an analog signal of a gear request according to the rotating angle of a magnet; in the process that the gear shifting plate rotates along with the gear shifting handle, a pressing structure on the gear shiftingplate triggers a corresponding microswitch to enable the microswitch to output a switching signal of a gear request, and the gearbox controller achieves double recognition of gears according to the two sets of signals at the same time, so that the gear recognition accuracy is guaranteed, and the failure safety requirement is met.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an electronic gear shifter gear position dual output structure. Background technique [0002] The shifter for a car is a common device on a car. The gear position of the shifter is used to reflect the driver's intention. Therefore, the shifter needs to have a clear shift position and can be accurately displayed on the human-computer interface. Display the gear shift position to avoid the phenomenon that the driver lowers his head to shift gears, thereby increasing driving safety. With the continuous development of automotive electronics, the traditional mechanical shifter is replaced by an electronic shifter, and the driver's gear request is converted from mechanical to electrical signal transmission, but due to electromagnetic interference and sensor failure, the electrical signal There may be an output error when passing the gear request. For this reason, an accurate and r...
