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 neutral gear return control method, device and equipment and a storage medium. The method comprises the steps of obtaining state information of a new energy vehicle; judging whether the new energy vehicle meets a neutral gear return control condition or not according to the state information; and executing neutral gear return operation if the control condition is met. According to the technical scheme, an automatic gearbox can be switched from a driving gear to a neutral gear through operations such as vehicle sound reminding, handle forced neutralgear return and automatic gearbox neutral gear return. The method has the advantages that the service life of the automatic gearbox can be prolonged, the noise of a transmission system can be lowered,engine fuel consumption can be lowered, exhaust emissions can be reduced, meanwhile, the operating requirements of drivers of different styles can be met adaptively in the starting process, and the safety and brand competitiveness of the whole vehicle are improved.

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...
