A car gear shifting device

Abstract

The invention discloses an automobile gear shifting device, comprising a mounting base; the mounting base is provided with a gear shifting power input member; the gear shifting power input member is movably arranged and matched on the mounting base; gears are arranged in a rotating range of the gear shifting power input member so as to realize the gear shifting by means of rotation of the gear shifting power input member. The automobile gear shifting device also comprises an electronic gear selecting mechanism, which comprises a plurality of signals sensing collecting members relatively and fixedly arranged on the mounting base or the gear shifting power input member and signal sensing applying members correspondingly arranged with the signal sensing collecting members. The automobile gear shifting device is characterized by further comprising a gear signal detection mechanism for signal detection when the gear shifting power input member rotates to each gear in a gear shifting process realized through the rotation of the gear shifting power input member. The automobile gear shifting device has the advantages that the structure is simple, safety is improved, reliability of gear shifting operation is improved, the driving convenience is improved under the condition that automobile safety risk is reduced so as to facilitate fault processing, and the like.

Description

technical field [0001] The invention relates to the field of automobile control systems, in particular to an automobile shifting device. Background technique [0002] The car shifting device is a device used to perform gear shift selection on a car. At present, there are two types of gear selection mechanisms for automobile gearboxes. One is the traditional gear selection device that uses a mechanical fork, commonly known as a manual gear. Drive the gears to move to realize gear shifting, and switch between the parking gear (P gear), reverse gear (R gear), neutral gear (N gear) and driving gear (D1-D6). The other is to use an electronic gear selection device, commonly known as an automatic gear, that is, to drive the electronic gear selection mechanism to move by manipulating the rotation angle of the shift lever to realize the parking gear (P gear), reverse gear (R gear), and neutral gear (N gear). ) and driving gear (D gear) switching signal input collection, the signal ...

Problems solved by technology

But at the same time, because the Hall sensor is an electronic product, it also relies on the connection between the circuit and the central processor to transmit signals. Therefore, under the influence of factors such as vibration and dust in the long-term driving of the vehicle, there is still a risk of failure to collect the shift signal, resulting in shifting. Gearbox operation failure, forced driving is likely to cause major safety accidents

[0005] Currently, BMW and jaguar , land rover Many of its models use electronic gear selection devices. If there is an appeal failure or a short circuit, in order to ensure safety, the power output end of the car is often forcibly locked to avoid problems caused by the inability to shift gears. Driving safety risk, after it is forced to lock and stop, the electronic gear selection device cannot release the current gear, and can only rely on towing and rescue, which brings inconvenience to driving operation
