A kind of automobile electronic gear shifter, control method and controller

Abstract

The invention discloses an automobile electronic gear shifter, a control method and a controller. The automotive electronic shifter includes a shift lever, a shift base, and a controller. The shift base is provided with a plurality of shift positions, and the shift lever moves on the shift base and can be switched between the multiple shift positions The second detection element outputs an output signal including an in-position signal or a reset signal according to the relative positional relationship with the first detection element; when the shift lever is switched from a shift position to another shift position, the first detection element triggers at least The three second detection elements change the output signals; the controller switches the shift position of the automobile according to the output signals of the plurality of second detection elements. On the basis that the hardware remains unchanged and the cost does not increase, the present invention improves the fault redundancy rate, and reduces the probability of vehicle performance prompting a fault. Finally, through the control of the safety mode, it is ensured that the vehicle can move slowly under special circumstances, so as to solve the problem that the vehicle cannot move if the P block is not cut out.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile electronic gear shifter, a control method and a controller. Background technique [0002] Existing automotive electronic shifters generally use magnets and Hall sensors to detect the position of the shift lever. The magnet and the Hall sensor are respectively arranged on the shift lever and the shift base, and the position of the magnet relative to the Hall sensor is detected by the action of the Hall sensor and the magnet, thereby judging the position of the shift lever on the shift base , and trigger the shift of the car transmission. [0003] However, in the existing electronic shifter, when the gear is switched, only one or two signals change for each gear change of the electrical signal generated by the Hall sensor. Such a signal change cannot determine the gear position when the sensor fails, resulting in a gear shift failure. SUMMARY OF THE INVENTION ...

AI Technical Summary

Problems solved by technology

[0004] Based on this, it is necessary to provide an automotive electronic shifter, control method and controller for the technical problem that the electronic shifter in the prior art cannot judge the gear position when a small number of sensors fail, resulting in the failure of shifting.
