[0083] 泄漏量可从变速器流体栗到变速器流体栗变化,但车辆制造商可能要求所有变速器流体栗泄漏小于或等于预定最大可允许泄漏量。 [0083] the amount of leakage from the transmission fluid may chestnut chestnut to the transmission fluid change, but may require that all vehicle manufacturers chestnut transmission fluid leak less than or equal to a predetermined maximum allowable leakage rate. 仅仅是举例,车辆制造商可能要求泄漏量小于大约4升/分钟(LPM)、大约5LPM、或另一个合适的最大可允许泄漏量。 Of example only, the vehicle manufacturer may claim the amount of leakage of less than about 4 liters / minute (LPM), about 5LPM, or another suitable maximum allowable leakage.

[0084] 预定最大可允许泄漏量可通过管线压力和/或变速器流体的温度而改变。 [0084] predetermined maximum allowable leakage rate can be varied by line pressure and / or temperature of the transmission fluid. 与管线压力和/或变速器流体温度关联的预定最大可允许量的值的映射可存储在诸如存储器236 的存储器中。 Predetermined maximum allowable amount of the mapping from the line pressure and / or transmission fluid temperature associated value may be stored in memory such as the memory 236.

[0087]目标速度模块224因此进一步基于变速器流体栗116的效率240来确定目标速度228。 [0087] Therefore, the target speed module 224 is further based on the efficiency of the transmission fluid chestnut 116 240 228 to determine the target speed. 目标速度模块224可使用将变速器流体栗116的目标流率208、预定最大泄漏232和效率240与目标速度228关联的函数和映射之一来确定目标速度228。 Target speed module 224 can use the transmission fluid chestnut target flow rate of 116 208, the mapping function and predetermined one of the biggest leaks and efficiency 232 240 228 associated with the target speed to determine the speed of the target 228. 例如,目标速度模块224可使用如下公式确定目标速度228: For example, the target speed of the module 224 may target speed determined by the equation 228:
