Clutch control system
A clutch control system includes a clutch, and a control unit. The control unit includes one or more processors, and one or more memories configured to store an executable instruction(s). The one or more processors are configured, in accordance with the instruction, to: acquire an engine torque; based on the engine torque, calculate a base transmission torque of the clutch; calculate a first transmission torque of the clutch by limiting, based on a first limiting condition, an amount of change of the base transmission torque; based on the first transmission torque, control the clutch; during return from a fuel cut, calculate a second transmission torque of the clutch by limiting the amount of change of the base transmission torque based on a second limiting condition that is more limiting than the first limiting condition; and, during return from the fuel cut, control the clutch based on the second transmission torque.
1. A clutch control system for a vehicle, the clutch control system comprising:
a clutch disposed in a path of transmission between an engine and a wheel of the vehicle; and
a control unit configured to control the clutch,
the control unit comprising
one or more processors, and
one or more memories configured to store one or more instructions to be executed by the one or more processors,
the one or more processors being configured, in accordance with the one or more instructions, to
acquire an engine torque,
based on the engine torque, calculate a base transmission torque of the clutch,
calculate a first transmission torque of the clutch by limiting, based on a first limiting condition, an amount of change of the base transmission torque,
based on the first transmission torque, control the clutch,
during return from a fuel cut, calculate a second transmission torque of the clutch by limiting, based on a second limiting condition, the amount of change of the base transmission torque, the second limiting condition limiting the amount of change further than does the first limiting condition, and
during return from the fuel cut, control the clutch based on the second transmission torque.
2. The clutch control system according to claim 1 ,
wherein the one or more processors are further configured, in accordance with the instruction, to, during return from the fuel cut, control the clutch based on the first transmission torque in response to the first transmission torque increasing to be greater than or equal to the second transmission torque.
3. The clutch control system according to claim 1 ,
wherein the one or more processors are further configured, in accordance with the instruction, to, when a predetermined period of time has elapsed since resumption of fuel injection, calculate the second transmission torque of the clutch by limiting, based on the first limiting condition, the amount of change of the base transmission torque.
