Problems solved by technology

Compared with traditional cars and pure electric vehicles, plug-in hybrid electric vehicles have more components and types, such as engines, motors, gearboxes, DCDC, etc., so the internal systems of plug-in hybrid electric vehicles are more complicated
Due to the driver's irregular operation or wrong operation, such as powering off the vehicle when the vehicle is in the driving gear, pulling up the handbrake without switching to neutral while the vehicle is driving, etc., it is easy to cause wear and tear on the transmission system, thereby reducing the use of the vehicle. Life, reduce vehicle fuel economy, etc., causing certain damage to the vehicle

Abstract

The invention discloses a new energy vehicle back-to-neutral control method, device, equipment and storage medium. The method includes: obtaining status information of the new energy vehicle; judging whether the new energy vehicle satisfies the control condition for returning to neutral gear according to the status information; It can switch the automatic transmission from the driving gear to neutral through the vehicle sound reminder, the handle is forced to return to neutral, and the automatic transmission is returned to neutral. The advantages include prolonging the service life of the automatic transmission, reducing the noise of the transmission system, and reducing engine fuel consumption. , reduce exhaust emissions, and at the same time, it can adapt to different styles of driver's operation needs during the start process, improving vehicle safety and brand competitiveness.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular, to a method, device, equipment and storage medium for controlling a return to neutral gear of a new energy vehicle. Background technique [0002] A plug-in hybrid vehicle is a transitional vehicle from a traditional vehicle to a pure electric vehicle. Because it can charge the power battery through an external power supply, a plug-in hybrid vehicle is also a new energy vehicle. Compared with traditional cars and pure electric vehicles, plug-in hybrid electric vehicles have more components and types, such as engines, motors, gearboxes, DCDC, etc., so the internal systems of plug-in hybrid electric vehicles are more complicated. Due to the driver's irregular operation or wrong operation, such as powering off the vehicle when the vehicle is in the driving gear, pulling up the handbrake without switching to neutral while the vehicle is driving, etc., it i...
