[0067] 泄漏量可从变速器流体泵到变速器流体泵变化,但车辆制造商可能要求所有变速器流体泵泄漏小于或等于预定最大可允许泄漏量。 [0067] leakage of the fluid can be pumped from the transmission to the transmission fluid pump changes, but the vehicle manufacturer may require that all transmission fluid pump leakage is less than or equal to a predetermined maximum allowable leakage. 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。 Way 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.

[0068] 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。 [0068] a predetermined maximum allowable leakage rate can be changed by the 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。 A predetermined maximum allowable amount of the mapping from the line pressure and / or transmission fluid temperature associated values can be stored in memory such as memory 236 in.

[0070] 基于预定最大泄漏232确定目标速度228确保变速器流体泵116实现目标流率208,即使变速器流体泵116的实际泄漏量等于预定最大泄漏232。 [0070] 232 is determined based on a predetermined maximum leakage target speed to ensure transmission fluid pump 228 116 208 to achieve the target flow rate, even if the amount of actual leak transmission fluid pump 116 is equal to a predetermined maximum leakage 232. 然而,如果变速器流体泵116的实际泄漏量小于预定最大泄漏232,则变速器流体泵116可以在大于实现目标流率208所需的速度下操作。 However, if the transmission fluid pump 116 is less than the actual leakage predetermined maximum leak 232, the transmission fluid pump 116 may be operated at a flow rate greater than required to achieve the target speed 208.

[0071]目标速度模块224因此进一步基于变速器流体泵116的效率240来确定目标速度228。 [0071] Thus the target speed module 224 further based on the transmission efficiency of the fluid pump 116 to determine a target speed of 240 228. 目标速度模块224可使用将变速器流体泵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 may be used to target the transmission fluid pump flow rate of 116, 208, one of the mapping function and predetermined maximum leakage and efficiency 240 232 228 associated with the target rate to determine the target speed 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 module 224 can use the following formula to determine the target speed 228:

Displacement Displacement

其中,Target Speed为目标速度228, Target Flow为目标流率208, Max为预定最大泄漏232,Eff iciency为效率240,效率240是在0.0 (指示等于预定最大泄漏232的泄漏)和预定最大泄漏的负值(指示无泄漏)之间的偏移值,并且Displacement为变速器流体泵116的排量。 Wherein, Target Speed target speed 228, Target Flow target flow rate 208, Max is a predetermined maximum leakage 232, Eff iciency of efficiency 240, 240 efficiency is 0.0 (indicating equal to a predetermined maximum leakage leakage 232) and a predetermined maximum leakage negative value (indicating no leak) between the offset value, and a transmission fluid pump displacement Displacement of 116.

[0072]目标速度模块224可进一步基于诸如用以提供冷却的一个或多个流率和阀体泄漏(例如,速率)的一个或多个其它参数来确定目标速度228。 [0072] Target velocity module 224 may be further based on one or more other parameters such as for providing one or a plurality of cooling flow rates and valve leak (e.g., speed) to determine a target speed 228. 例如,在除以排量之前,目标速度模块224可将用以提供冷却的流率和阀体泄漏与以上公式的分子求和。 For example, prior to displacement divided by the target speed module 224 may be used to provide cooling of the leakage flow rate and the valve body with the above summation formula molecule. 阀体泄漏可表示阀体132的泄漏速率。 Valve leakage may represent leakage rate of the valve body 132. 目标速度模块224可以例如基于由变速器流体泵116输出的变速器流体的变速器流体温度和压力来确定阀体泄漏和用以提供冷却的流率。 Target speed module 224 may, for example based on transmission fluid temperature and pressure of the transmission fluid transmission fluid pump output 116 to determine the valve leaks and to provide cooling of the flow rate.

[0073] 速度控制模块242基于目标速度228将功率施加到变速器流体泵116。 [0073] speed control module 242 228 applying power to the transmission fluid pump 116 based on the target speed. 例如,速度控制模块242可基于目标速度228来确定将施加到变速器流体泵116的脉冲宽度调制(PWM)占空比,并且以该占空比将功率施加到变速器流体泵116。 For example, speed control module 242 may be determined based on the target speed 228 is applied to the transmission fluid pump 116 is a pulse width modulation (PWM) duty cycle and the duty cycle to be applied to a power transmission fluid pump 116.

[0074] 效率模块244确定变速器流体泵116的效率240。 [0074] module 244 determines the efficiency of the transmission efficiency of the fluid pump 116 240. 效率模块244基于用于具有等于预定最大泄漏232的泄漏的变速器流体泵的预定数据和在向公众提供车辆之前为变速器流体泵116获得的数据来确定变速器流体泵116的效率240。 Efficiency module 244 232 to book a predetermined maximum leakage data leakage and data transmission fluid pump before providing public access to the vehicle transmission fluid pump 116 is based on having a size equal to determine the efficiency for transmission fluid pump 116 240.

[0075] 更具体而言,效率模块244基于在对于具有预定最大泄漏232的变速器流体泵来说发生变速器流体压力减小时的泵速度来确定变速器流体泵116的效率240。 [0075] More specifically, the efficiency of the pump module 244 based on the transmission speed is reduced to the transmission of fluid pressure having a fluid pump 232 for a predetermined maximum leakage occurs to determine the efficiency of the transmission fluid pump 116 240. 该泵速度为预定速度248,并且可以存储在存储器236中。 The pump 248 speed is a predetermined speed, and may be stored in the memory 236.

[0076] 效率模块244进一步基于在使用变速器流体泵116发生变速器流体压力减小时的变速器流体泵116的速度来确定变速器流体泵116的效率240。 [0076] Module 244 further efficient use of the transmission based on the transmission fluid pump 116 occurs when the fluid pressure decreases transmission fluid pump speed 116 to determine the efficiency of the transmission fluid pump 116 240. 在向公众提供车辆之前进行的测试期间,变速器流体压力被监测,以确定变速器流体泵116的泵速度。 During the test before offering to the public by a vehicle, the transmission fluid pressure is monitored to determine the transmission fluid pump 116.
