Embodiment 1

[0059] see figure 1 , is a flow chart of the automobile gear position control method provided in the first embodiment of the present invention, including steps:

[0060] Step S10, collecting the original gear position of the current vehicle shifter to obtain the original gear position;

[0061] Wherein, in this step, the position of the original gear is collected by controlling the electronic gear switch to obtain the original gear signal, and the original gear signal is filtered to remove the jitter signal and sent to the vehicle control device, the vehicle controller processes the signal to obtain the original gear position;

[0062] Step S20, obtaining the shift position of the shifter, and determining the required gear according to the original gear and the shift position;

[0063] Wherein, the required gear is the gear after judging the driver's intention and analyzing the driving situation according to the situation;

[0064] Step S30, obtaining the power-on state and...

Embodiment 2

[0069] see figure 2 , is a flow chart of the automobile gear position control method provided in the second embodiment of the present invention, including steps:

[0070] Step S11, collecting the original gear position of the current vehicle shifter to obtain the original gear position;

[0071] Wherein, in this step, the position of the original gear is collected by controlling the electronic gear switch to obtain the original gear signal, and the original gear signal is filtered to remove the jitter signal and sent to the vehicle control device, the vehicle controller processes the signal to obtain the original gear position;

[0072] Step S21, when the shift time of the shift position in R, D or N is greater than the time threshold, then it is determined that the required gear corresponds to R, D or N;

[0073] Wherein, the time threshold can be set independently according to user needs. In this embodiment, the time threshold is 50ms. Preferably, the time threshold can a...

Embodiment 3

[0102] see image 3 , is a flow chart of the automobile gear position control method provided by the third embodiment of the present invention, including steps:

[0103] Step S12, after the EPP wakes up, perform an initialization self-inspection; after the self-inspection is completed, send information such as the state of the P gear, the state of the P gear sensor, and the fault state to the vehicle controller;

[0104] Step S22, after the SCU wakes up, it performs an initialization self-check; after the self-check is ok, it sends its own P, N lock position feedback, gear position signal, gear failure status and other information to the vehicle controller;

[0105] Step S32, the vehicle controller processes the original signal of the gear position, judges the required gear position, calculates the actual gear position, and judges the displayed gear position according to the basic information provided by the SCU and EPP;

[0106]Step S42, the vehicle controller provides the c...

Abstract

The present invention is applicable to the technical field of automobiles, and provides an automobile gear position control method, system, vehicle-mounted terminal and storage medium. The method includes: collecting the original gear position of the current vehicle shifter to obtain the original gear position; Obtain the shift position of the shifter, determine the required gear according to the original gear position and shift position; obtain the power-on state and driving state of the current vehicle, and obtain the locking state of the P gear lock of the current vehicle; The actual gear position is determined according to the power state, locked state and required gear position, and the driving state is controlled and switched according to the actual gear position. The present invention collects and determines the actual gear position based on the driving state, power-on state, locked state, and required gear position, so that the actual gear position state can be accurately determined, and the switching control of the current vehicle state is carried out correspondingly according to the actual gear position, preventing the The phenomenon that the accuracy of gear position control is low due to the collection of the current gear position based on the shifter and the driving state of the car.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an automobile gear position control method, system, vehicle-mounted terminal and storage medium. Background technique [0002] In recent years, with the rapid development of new energy vehicles, different types of pure electric vehicles account for an increasing proportion of the market, and the safety design of the vehicle control for pure electric vehicles is also the top priority in the development tasks of major automobile manufacturers. [0003] On a pure electric vehicle, the vehicle parking, forward, reverse and neutral coasting control are usually the response of the relevant control mode by the vehicle controller according to the logical gear position given by the automatic transmission control unit TCU; the electronic gear As a device that directly perceives the user's driving intention when driving, the positioner SCU collects the gear position signal a...
