Abstract
The present invention relates to a method of protecting a starting clutch that generates an estimated equivalent temperature of the starting clutch and performs an operation for protecting the starting clutch if the estimated temperature exceeds critical temperature, in order to prevent the burnout of the starting clutch caused by excessive slip under severe conditions.
Claims14
A method of protecting a starting clutch of a vehicle, the method comprising:
- a first step of calculating a friction temperature of the starting clutch;
- a second step of calculating a cooling temperature of the starting clutch;
- a third step of generating an estimated equivalent temperature of the starting clutch by subtracting the cooling temperature of the starting clutch from the friction temperature of the starting clutch;
- and
- a fourth step of performing an operation for protecting the starting clutch if the estimated equivalent temperature of the starting clutch exceeds a predetermined critical temperature.
A system including a processor and a memory storing instructions executable by the processor, wherein the processor, when executing the instructions performs a plurality of steps comprising:
- a first step of calculating a friction temperature of the starting clutch;
- a second step of calculating a cooling temperature of the starting clutch;
- a third step of generating an estimated equivalent temperature of the starting clutch by subtracting the cooling temperature of the starting clutch from the friction temperature of the starting clutch;
- and
- a fourth step of performing an operation for protecting the starting clutch if the estimated equivalent temperature of the starting clutch exceeds a predetermined critical temperature.
