Abstract

The invention relates to a vehicle neutral sliding control method, an automatic gearbox and a vehicle. The control method comprises the steps that a first running state parameter of the vehicle is obtained; judging whether the first running state parameter meets a first preset condition or not; if yes, the vehicle is controlled to enter a neutral sliding state; acquiring a second running state parameter of the vehicle; judging whether the second running state parameter meets a second preset condition or not; if yes, the vehicle is controlled to exit the neutral sliding state. According to the control method for neutral sliding of the vehicle, the frequency of entering and exiting of the neutral sliding mode is reduced, the time proportion of neutral sliding is increased, the fuel consumption of the whole vehicle is reduced, and the thermal management performance is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle gearboxes, and in particular, to a control method for a vehicle sliding in neutral, an automatic gearbox and a vehicle. Background technique [0002] This section provides merely background information related to the present disclosure and is not necessarily prior art. [0003] Electronically controlled mechanical transmission (Automated Mechanical Transmission, AMT) does not require the driver to shift gears, greatly reduces labor intensity, and can also save fuel consumption, so it is more and more common for vehicles to match AMT. As an optional control strategy of AMT automatic transmission, when the driver releases the accelerator pedal, the transmission will control the clutch after the allowable time, and the transmission will coast in neutral, reducing the transmission resistance of the transmission system. , make the whole vehicle glide farther, so as to achieve the purpose of fu...
