Problems solved by technology

For vehicles equipped with AT and DCT transmissions, when the vehicle starts to coast from high speed to low speed, the engine and transmission system of the vehicle will not be disconnected, and the vehicle will drag the engine to run backwards. The speed of the vehicle decreases too fast, resulting in a short gliding distance of the vehicle, and if the driver steps on the gas pedal to accelerate during gliding, the vehicle will have a more obvious sense of frustration due to the sudden increase in speed, and the user experience is not good

Abstract

The invention relates to a vehicle control method, a vehicle control device and a vehicle, and aims to increase a coasting distance of the automatic transmission vehicle and reduce a sense of abruptness generated when a driver presses an accelerator to accelerate during deceleration and downshifting. The vehicle control method comprises the steps of controlling a lock-up clutch of the vehicle to be in an open state during coasting of the vehicle so as to disconnect an engine of the vehicle from a transmission system, judging whether an accelerator pedal signal of the vehicle is detected, determining a gear position which matches a current vehicle speed when the accelerator pedal signal is detected, and controlling a state of the lock-up clutch and a torque response time of the engine according to the gear position so as to enable the vehicle to shift to the gear position and travel in the gear position.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular, to a vehicle control method, device and vehicle. Background technique [0002] With the continuous development of science and technology, vehicle technology has also been continuously developed. Among them, automatic transmission vehicles do not require drivers to manually shift gears due to the use of automatic transmissions. The operation is simple, which greatly facilitates people's travel. [0003] In the related art, automatic transmissions used in automatic transmission vehicles include AT (Automatic Transmission, hydromechanical automatic transmission), DCT (Dual Clutch Transmission, dual clutch transmission), CVT (ContinuouslyVariable Transmission, continuously variable transmission), and the like. For vehicles equipped with AT and DCT transmissions, when the vehicle starts to coast from high speed to low speed, the engine and transmission system of the vehicle wi...
