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 present disclosure relates to a vehicle control method, device and vehicle to increase the gliding distance of an automatic transmission vehicle and reduce the frustration of the vehicle when the driver steps on the accelerator to accelerate during deceleration and downshifting. The vehicle control method of the present disclosure includes: during the coasting process of the vehicle, controlling the lock-up clutch of the vehicle to be in an open state, so that the engine and the transmission system of the vehicle are disconnected; Accelerator pedal signal; when the accelerator pedal signal is detected, determine the gear that matches the current vehicle speed; according to the gear, control the state of the lock-up clutch and the torque response time of the engine so that the The vehicle is switched to the gear for driving.

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...
