Problems solved by technology

Take the ACC (Adaptive Cruise Control) working condition in ADAS as an example. When the vehicle is actively decelerating or braking in ACC, the ESP system will provide braking force. At this time, the automatic transmission cannot know the braking force. If The torque transmitted by the automatic transmission (the driving force of the car) is relatively large, and the braking force will conflict with the torque transmitted by the automatic transmission, resulting in unstable vehicle speed, loud braking noise, braking rush and jerky vibration, etc.

Abstract

The invention provides a clutch control method and device, and a computer readable storage medium, and belongs to the field of vehicles. The control method comprises the steps of after a function of an advanced driving assistance system of the vehicle is activated, acquiring a four-wheel braking force provided by an electronic stabilization program system; determining brake master cylinder pressure equivalent to the four-wheel brake force; and controlling the state of a clutch based on the brake master cylinder pressure equivalent to the four-wheel brake force.

Description

technical field [0001] The present disclosure relates to the field of automobiles, and in particular, to a clutch control method, a device and a computer-readable storage medium. Background technique [0002] An automatic transmission is a transmission device that automatically shifts gears by controlling the clutch according to the vehicle speed and engine speed. Some automatic transmissions support the operation of ADAS (Advanced Driving Assistance System). Vehicles under ADAS control will use the automatic transmission to control the clutch during the entire process from starting, normal driving to parking, to temporarily separate or gradually engage the engine and the driveline to cut off or transmit the power output from the engine to the driveline. [0003] ADAS is provided by ESP (Electronic Stability Program, Electronic Stability Program) system to provide braking force such as deceleration braking. Taking the ACC (Adaptive Cruise Control) working condition in ADAS...
