Electronic gear shifting device

Abstract

The invention provides an electronic gear shifting device and relates to electronic gear shifting technologies. The electronic gear shifting device comprises a Hall sensor unit, a gearbox control unit, an electronic gear shifting control unit and a man-machine interaction unit, wherein the Hall sensor unit is used for detecting operation of a driver to a gear shifting handball; the gearbox control unit is sued for conducting the gear shafting action and detecting the gear of a gearbox of a vehicle; the electronic gear shifting control unit is used for acquiring the gear shifting intention of the driver through the Hall sensor unit and judging whether the gear shifting intention of the driver is dangerous, and/or the danger level of the gear shifting intention of the driver on the basis of the obtained gear of the gearbox and the obtained speed of the vehicle, and the electronic gear shifting control unit controls the gearbox control unit to carry out corresponding gear shifting operation to respond the judgment that the gear shifting intention of the driver is safe, and the judgment is made by the electronic gear shifting control unit; and the man-machine interaction unit can give an alarm to the driver, and the alarm is used for respond the judgment that the gear shifting intention of the driver is dangerous and/or the danger level, and the judgment is made by the electronic gear shifting control unit. When it is judged that the operation of the driver is dangerous, alarming or prompting is conducted through the man-machine interaction unit.

Description

technical field [0001] The invention relates to electronic shifting technology, in particular to an electronic shifting device. Background technique [0002] The transmission produces variable speed and torque through different gear combinations; while the automatic transmission AT is composed of a hydraulic torque converter, planetary gears, hydraulic pitch change system and hydraulic control system, and achieves speed change through hydraulic transmission and gear combination. torque converter. Through a series of operations on the gearbox, the transmission ratio can be changed; when the engine rotation direction remains unchanged, the car can be driven backwards; the neutral gear is used to interrupt the power transmission, so that the engine can start, idle, and facilitate the transmission to shift gears or power output. Therefore, on the one hand, the gear position operation of the vehicle can make the driving of the vehicle more in line with the road conditions and t...

Problems solved by technology

[0003] Although the vehicle gear shifting device in the prior art can meet the driver's needs to a certain extent, there are still some problems; The corresponding shift operation will cause safety accidents. For example, when the vehicle is running at high speed, the driver mistakenly puts the shift hand in the parking gear or low gear, which will cause the vehicle to be rear-ended; , the driver forgets to engage the park gear, which is very likely to cause the car to roll
