A car electronic gear selection mechanism

Abstract

The invention discloses an electronic gear selecting mechanism for an automobile. The electronic gear selecting mechanism for the automobile comprises an installing base which is provided with a gear shifting power input component; and a plurality of gear positions are arranged within the movement range of the gear shifting power input component. The electronic gear selecting mechanism for the automobile further comprises a plurality of signal induction and acquisition components relatively and fixedly arranged on the installing base or the gear shifting power input component and signal induction components arranged corresponding to the signal induction and acquisition components; the signal induction components are relatively and fixedly arranged on the gear shifting power input component or the installing base; and the signal induction components can enter the induction range of the signal induction and acquisition components to achieve signal acquisition when the gear shifting power input component moves and shifts gears. The electronic gear selecting mechanism for the automobile is characterized in that the number of the signal induction and acquisition components is at least two, and the number of the signal induction components is at least two. The electronic gear selecting mechanism for the automobile has the beneficial effects of being simple in structure, capable of improving the safety performance and improving gear shifting operation reliability, capable of improving the driving convenience and fastness to facilitate fault treatment under the condition that the safety risk of the automobile is reduced and the like.

Description

technical field [0001] The invention relates to the field of automobile control systems, in particular to an automobile electronic gear selection mechanism. 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 col...

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
