具体实施方式 detailed description

[0065] 发动机为车辆生成扭矩。 [0065] the vehicle engine to generate torque. 变速器将扭矩传递到车辆的一个或多个车轮。 A transmission torque to the vehicle wheels or more. 变速器流体栗将变速器流体从变速器流体源(例如,贮槽)栗送至变速器的各个部件,例如离合器。 Li transmission fluid transmission fluid transmission from a fluid source (e.g., reservoir) of the transmission to the various components of Li, such as clutch. 变速器流体栗为电动栗。 Li Li is an electric transmission fluid. 控制模炔基于目标流率来控制变速器流体栗的速度。 Alkynyl control module to control the speed of the transmission based on the target fluid flow rate Li.

[0066] 所有变速器流体栗都泄漏,例如在旋转部件和内壁之间。 [0066] Li are all leakage of transmission fluid, for example between the rotating member and the inner wall. 车辆制造商可能需要所有变速器流体栗泄漏(内部)小于或等于预定最大可允许量。 All vehicle manufacturers may require transmission fluid leak Li (inside) is less than or equal to a predetermined maximum allowable amount. 控制模块可基于预定最大可允许量控制变速器流体栗的速度,以确保在变速器流体栗的泄漏等于预定最大可允许量时变速器流体栗实现目标流率。 The control module may be based on a predetermined maximum allowable speed of the transmission amount control fluid chestnut, to ensure a leak transmission fluid transmission fluid Li Li is equal to a predetermined target flow rate to achieve the maximum allowable amount.

[0067] 然而,如果变速器流体栗的泄漏小于预定最大可允许量,则变速器流体栗可被控制到比所需更快的速度。 [0067] However, if the leakage of the transmission fluid is less than a predetermined Li maximum allowable amount, the transmission fluid may be controlled to Li faster than needed. 本公开的控制模块因此确定相对于具有等于预定最大可允许量的泄漏的变速器流体栗的变速器流体栗的效率。 Thus the control module of the present disclosure determines the efficiency with respect to the transmission of fluid equal to the predetermined maximum allowable amount of Li leakage of transmission fluid chestnut. 控制模块进一步基于变速器流体栗的效率来控制变速器流体栗的速度。 The control module further controls the speed of the transmission efficiency of the transmission fluid based on the fluid chestnut chestnut. 基于效率控制变速器流体栗的速度可以使变速器流体栗能够以较低速度操作并且因此消耗较少能量。 Li can make the transmission fluid velocity based on the transmission efficiency of the control fluid Li can operate at lower speeds and thus consume less energy.

[0080]现在参看图3,提供了示例性栗控制系统的功能框图。 [0080] Referring now to FIG. 3, a functional block diagram of an exemplary control system Li. 栗控制模块135可在TCM 70 内或在另一个合适的模块内单独地实施。 Li control module 135 may be implemented separately or in another appropriate module within the TCM 70. 目标流率模块204确定由变速器流体栗116输出的变速器流体的目标流率208。 Target flow rate module 204 determines a target flow rate of fluid output by the transmission of the transmission fluid Li 116 208. 目标流率模块204可以例如基于目标压力212、一个或多个润滑请求216、一个或多个冷却请求220、和/或一个或多个其它参数来确定目标流率208。 Module 204 may target flow rate 212, one or more lubricating request 216, one or more cooling request 220, and / or one or more other parameters to determine a target flow rate based on the target pressure, for example 208.

[0082]目标速度模块224基于目标流率208来确定变速器流体栗116的目标速度228。 [0082] The target speed based on the target flow rate module 224 determines a target speed of the transmission 208 116 228 Li fluid. 然而,包括变速器流体栗116在内的所有变速器流体栗都在一定程度上(在内部)泄漏。 However, all transmission fluid comprising Li Li 116, including a transmission fluid are to some extent (internal) leak. 例如, 变速器流体可以由于旋转部件和内壁之间的间隙而在变速器流体栗116的旋转部件和变速器流体栗116的内壁之间泄漏。 For example, the transmission fluid may leak between the inner rotating member 116 Li transmission fluid and transmission fluid 116.

[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] leakage of fluid from the transmission to be Li Li transmission fluid changes, the vehicle manufacturer may require that all transmission fluid leakage Li equal to or less than the 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。 For example only, the vehicle manufacturer may require a leakage of less than about 4 liters / minute (the LPM), about 5LPM, or other 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] predefined 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。 The amount of allowable mappings associated with line pressure and / or temperature of the transmission fluid of a predetermined maximum value may be stored in memory such as the memory 236.

[0085]目标速度模块224确定预定最大泄漏232,并且进一步基于预定最大泄漏232确定目标速度228。 [0085] module 224 determines a predetermined target speed maximum leakage 232, and further based on a predetermined maximum leak 232 determines the target speed 228. 目标速度模块224可从基于管线压力和/或变速器流体温度的映射来确定预定最大泄漏232,或者预定最大泄漏232可以是恒定值。 Target rate module 224 may determine from the map based on the line pressure and / or temperature of a predetermined maximum transmission fluid leak 232, or a predetermined maximum leakage 232 may be a constant value.

[0086] 基于预定最大泄漏232确定目标速度228确保变速器流体栗116实现目标流率208, 即使变速器流体栗116的实际泄漏量等于预定最大泄漏232。 [0086] 232 determines a target speed based on a predetermined maximum transmission fluid leak 228 ensure Li 116 208 to achieve a target flow rate, even if the actual transmission fluid leak amount Li is equal to the predetermined maximum leakage 116 232. 然而,如果变速器流体栗116的实际泄漏量小于预定最大泄漏232,则变速器流体栗116可以在大于实现目标流率208所需的速度下操作。 However, if the actual transmission fluid leakage Li 116 232 leakage is less than a predetermined maximum, the transmission fluid Li 116 may operate at a speed to achieve the desired target flow rate is greater than 208.

[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] Thus the target speed module 224 further determines the target speed 240 228 116 based on the efficiency of the transmission fluid Li. 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 may use the transmission target flow rate of fluid Li 116 208, one mapping function 228 and 240 associated with the target speed and efficiency predetermined maximum leak 232 228 to determine the target speed. 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 may use the following equation to determine the target speed 228:

[0092]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。 [0092] The target speed module 224 may further be based on one or more other parameters such as cooling or to provide a plurality of flow rate and valve leak (e.g., rate) 228 determines the target speed. 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 a cooling leak flow rate and the valve body with the above formula molecules summed. 阀体泄漏可表示阀体132的泄漏速率。 Leak valve 132 may represent the leakage rate of the valve body. 目标速度模块224可以例如基于由变速器流体栗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。 Module 224 may, for example, the target speed based on the transmission fluid temperature and pressure of the fluid outputted by the transmission of the transmission fluid to determine Li 116 and the valve body to provide a leak flow rate of cooling.

[0093] 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栗116。 [0093] The rate control module 242 based on the target speed 228 is applied to a power transmission fluid 116 Li. 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栗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栗116。 For example, speed control module 242 may be determined based on the target speed 228 is applied to the pulse width modulation transmission fluid 116 Li (PWM) duty cycle, and in that the duty cycle applied to the power transmission fluid 116 Li.

[0094] 效率模块244确定变速器流体栗116的效率240。 [0094] The efficiency of the efficiency of the transmission module 244 determines 116 240 Li fluid. 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栗的预定数据和在向公众提供车辆之前为变速器流体栗116获得的数据来确定变速器流体栗116的效率240。 Efficiency module 244 of the leakage predetermined maximum predetermined data 232 for transmission based on the fluid equal to Li and Li to determine the efficiency of the transmission fluid is 116 to 240 before the vehicle providing the public data transmission fluid 116 Li obtained.

[0095]更具体而言,效率模块244基于在对于具有预定最大泄漏232的变速器流体栗来说发生变速器流体压力减小时的栗速度来确定变速器流体栗116的效率240。 [0095] More specifically, the efficiency of the module 244 based on Li fluid pressure reduction speed of the transmission occurred for the transmission fluid having a predetermined maximum leakage Li 232 for determining efficiency when the transmission fluid Li 116 240. 该栗速度为预定速度248,并且可以存储在存储器236中。 The speed is a predetermined speed Li 248, and may be stored in memory 236.

[0096]效率模块244进一步基于在使用变速器流体栗116发生变速器流体压力减小时的变速器流体栗116的速度来确定变速器流体栗116的效率240。 [0096] module 244 determines the efficiency of the efficiency of the transmission fluid Li 116 240 further based on the speed of transmission fluid Li Li 116 when the transmission fluid decreases transmission fluid pressure occur with 116. 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,以确定变速器流体栗116的栗速度。 During the tests carried out prior to providing the public vehicle, the transmission fluid pressure is monitored to determine the speed of the transmission fluid Li Li 116. 该栗速度将被称为测试栗速度252。 The speed will be referred to as test Li Li 252 speed.

[0097] 在其中效率240是在0.0和1.0之间的增益值的实施中,效率模块244可将效率240 设置为等于测试栗速度252除以预定速度248。 [0097] In the embodiment where the gain in efficiency is 240 values ​​between 0.0 and 1.0, the efficiency of the module 244 may be set equal to the efficiency of the test 240 252 Li speed by a predetermined speed 248. 在其它实施中,效率模块244可使用将测试栗速度252和预定速度248与效率240关联的函数和映射之一来确定效率240。 In other embodiments, the efficiency of the module 244 may use the mapping function 240 and one associated with the speed 252 and the test Li predetermined speed and efficiency of determining the efficiency 248 240. 在各种实施中, 效率模块244可基于诸如变速器流体的压力和/或温度的一个或多个参数而选择性地调整预定速度248。 In various embodiments, the efficiency of the transmission module 244 may be a fluid, such as pressure and / or temperature of one or more parameters based on 248 selectively adjusting a predetermined speed.
