The embodiment of the invention provides a new energy vehicle neutral gear return control method, which can cope with 3 common situations occurring in the driving operation process of a driver: (1) the hand brake is suddenly pulled up by a driver in the driving gear running process of the vehicle, (2) the handle is directly in the driving gear after the whole vehicle is powered on and off, and (3) when the handle is in the driving gear, the driver steps on the brake pedal for a long time to stop the vehicle and wait to start the vehicle again.

In a specific example, as shown in fig. 1a, the specific process of this embodiment of the method is as follows:

step 1: judging whether the vehicle is in a driving gear, if not, operating, otherwise, carrying out the next step;

step 2: judging whether a driver pulls up a hand brake and the time for pulling the hand brake exceeds 3 seconds, if not, no operation is performed, otherwise, the next step is performed;

and step 3: executing system neutral return reminding, if the driver actively returns to neutral within 10 seconds of the neutral return reminding time, closing the neutral return reminding, and if not, performing the next step;

and 4, step 4: and forcibly executing a neutral return operation, including returning the handle to a neutral position, and continuously reminding the driver.

For the situation that the handle is directly in the driving gear after the whole vehicle is powered on and powered off, the implementation process of the method is as shown in fig. 1b, and specifically as follows:

step 1: if the handle is directly positioned on a driving gear (including a D gear and an R gear) after the vehicle is powered on and powered off on the key door, the next step is carried out, otherwise, no operation is carried out;

step 2: executing system neutral return reminding, if the driver actively returns to neutral within 10 seconds of the neutral return reminding time, closing the neutral return reminding, and if not, performing the next step;

and step 3: and forcibly executing a neutral return operation, including returning the handle to a neutral position, and continuously reminding the driver.

For the situation when the driver steps on the brake pedal for a long time to stop the vehicle and wait to start again, the implementation process of the method is shown in fig. 1c, and specifically as follows:

step 1: if the vehicle speed is 0 and the opening degree of the brake pedal is greater than 0, the next step is carried out, otherwise, no operation is carried out;

step 2: if the current vehicle is in the D gear or the R gear, the next step is carried out, otherwise, no operation is carried out and the brake timing is cleared;

and step 3: braking and timing in a driving gear state, and selecting the gear returning time of the gearbox according to the style of a driver in a week;

and 4, step 4: if the brake timing is greater than the neutral return time, the next step is carried out, otherwise, the step 2 is returned;

and 5: the gear box returns to a neutral gear, and the handle is kept unchanged;

step 6: if the brake pedal is 0 or the accelerator pedal is larger than 0, the next step is carried out, otherwise, the step 5 is returned to;

and 7: the gearbox is returned to drive.

Under the condition, the judgment of the driver style can be carried out in two stages, the first stage is that an automobile manufacturer collects, arranges and classifies data of drivers nationwide in the vehicle starting process based on the Internet of vehicles, and the second stage is that the vehicle judges the driver style based on the data collection of the drivers in the starting process of the last week. The first stage is shown in fig. 1d, and the specific process is as follows:

step 1: collecting data of drivers nationwide in the vehicle starting process, such as the opening degree of an accelerator pedal, the vehicle speed, the standard deviation of the vehicle speed and the starting time, and preprocessing the data, such as processing missing data and abnormal data;

step 2: dividing the style of a driver into 3 types of conservative type, general type and aggressive type, and initializing a clustering center;

and step 3: then calculating the Euclidean distance between each point and the cluster center, and distributing the Euclidean distance to each class;

and 4, step 4: updating the clustering center;

and 5: if the data is redistributed to different categories or the cluster center changes, the step 3 is returned, otherwise, the classification is finished.

The second stage is implemented as shown in fig. 1e, and the specific process is as follows:

step 1: if the vehicle belongs to a starting state, performing the next step, otherwise suspending data acquisition;

step 2: starting data acquisition, including accelerator pedal opening, vehicle speed standard deviation and starting time;

and step 3: if the starting time exceeds 5 seconds or the vehicle speed is more than 10m/s, finishing the data acquisition of a starting stage, otherwise returning to the step 2 to continue acquiring data;

and 4, step 4: analyzing the driving style of the starting state of the current driver based on the previous offline cluster analysis;

and 5: and determining the gear return-to-neutral time according to the style of the driver.

The conservative return-to-neutral time may be set to 1 second, the general return-to-neutral time may be set to 2 seconds, and the aggressive return-to-neutral time may be set to 3 seconds.

The flow of the vehicle starting state is shown in fig. 1f, and specifically includes the following steps:

step 1: if the key door is on, the next step is carried out, otherwise, the current vehicle is judged to be in a parking state,

step 2: if the D gear or the R gear is engaged in the non-parking state at present, the next step is carried out, otherwise, the current parking or neutral state is judged;

and step 3: and if the vehicle speed at the last moment or the initial moment is 0, the opening degree of a brake pedal is greater than 0, the opening degree of the brake pedal at the current moment is 0 or the opening degree of an acceleration pedal is greater than 0, judging that the current vehicle is in a starting state, otherwise, judging that the vehicle is in a parking or driving state.

Because the embodiment of the invention focuses on data collection of the vehicle starting state, the judgment of other states is fuzzy.

The neutral return control method of the embodiment of the invention is also applicable to all vehicles with automatic gearboxes. The time for the conservative type, the general type and the aggressive type to return to the neutral gear can be flexibly set, but the relative size relationship is kept unchanged.

According to the technical scheme, the state information of the new energy vehicle is acquired; judging whether the new energy vehicle meets a return-to-neutral control condition or not according to the state information; if the automatic transmission is satisfied with the requirements, the neutral return operation is executed to realize the operations of reminding through vehicle sound, forcibly returning to the neutral position through a handle, returning to the neutral position through the automatic transmission and the like, so that the automatic transmission is switched to the neutral position from a driving gear.
