Method and device for controlling state switching of fluid torque converter, and storage medium

A device for controlling state switching of a fluid torque converter, comprising:

• a target instruction obtaining module configured to obtain a target instruction when the fluid torque converter of a vehicle is in a locked state, wherein the target instruction triggers a change of a torque transmission direction of a transmission system of the vehicle;
• a target operating condition determining module configured to obtain a state parameter, and determine whether the vehicle is in a target operating condition according to the state parameter;
• and a state switching module configured to:
• if the vehicle is in the target operating condition, switch the fluid torque converter to an open state, and switch the fluid torque converter back to the locked state after maintaining the open state for a preset period of time;
• wherein the target operating condition determining module comprises:
• a target operating condition criterion obtaining unit configured to obtain target operating condition criterion;
• a state parameter obtaining unit configured to obtain a state parameter pointed by the target operating condition criterion;
• and a determining unit configured to determine whether the vehicle is in the target operating condition according to the state parameter and the target operating condition criterion.

A computer storage medium, wherein the computer storage medium stores at least one instruction or at least one program, the at least one instruction or at least one program is configured to be loaded and executed by a processor to implement a method for controlling state switching of a fluid torque converter comprising:

• obtaining a target instruction when the fluid torque converter of a vehicle is in a locked state, wherein the target instruction triggers a change of a torque transmission direction of a transmission system of the vehicle;
• obtaining a state parameter, and determining whether the vehicle is in a target operating condition according to the state parameter;
• and if the vehicle is in the target operating condition, switching the fluid torque converter to an open state, and switching the fluid torque converter back to the locked state after maintaining the open state for a preset period of time;
• wherein the obtaining a state parameter, and determining whether the vehicle is in a target operating condition according to the state parameter comprises:
• obtaining target operating condition criterion;
• obtaining a state parameter pointed by the target operating condition criterion;
• and determining whether the vehicle is in the target operating condition according to the state parameter and the target operating condition criterion.
