Vehicle shifting method

Abstract

The invention discloses a vehicle shifting method. The method comprises the following steps: moving a shifting power input component to input a shifting instruction; acquiring gear information input by the shifting power input component which is moved, and transmitting the gear information to an automobile electronic control unit to carry out processing; and outputting the shifting instruction by the automobile electronic control unit, and controlling an automobile power output end to execute a shifting operation. The method is characterized in that two signal acquisition manners such as electromagnetic induction detection and mechanical contact type detection are adopted to acquire the gear information input after moving the shifting power input component, and during the processing of the automobile electronic control unit, the shifting instruction is output after comparing and verifying the two pieces of acquired gear information. The method disclosed in the invention has the advantages of being simple to implement, improving the safety, improving the shifting operation reliability, and improving the driving convenience and facilitating the fault handling under the condition that the automobile safety risk is reduced.

Description

technical field [0001] The invention relates to the field of automobile control systems, in particular to a vehicle gear shifting method. 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...

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
