    • A method for controlling the temperature of transmission fluid in a motor vehicle includes operating in an automatic transmission fluid cooling mode, a heater priority mode entered by disabling automatic transmission fluid heating, and an automatic transmission fluid heating mode which includes sending hot engine coolant to a heat exchanger for heating the automatic transmission fluid by transferring heat from the hot engine coolant to the automatic transmission fluid. The method switches to from a heater priority mode to a transmission heating mode base on a number of sensed conditions including sensed automatic fluid transmission temperature. The method also includes an automatic transmission fluid temperature regulating mode including measuring an automatic transmission fluid temperature and switching between the cooling mode and the heating mode based measured temperature.
    • 用于控制机动车辆中的变速器流体的温度的方法包括以自动变速器油冷却模式操作,通过禁止自动变速器油液加热而进入的加热器优先模式,以及自动变速箱液体加热模式,其包括将热机冷却剂发送到 热交换器,用于通过将热量从热发动机冷却剂传递到自动变速器流体来加热自动变速器油。 该方法基于包括检测到的自动流体传输温度的感测条件的数量,从加热器优先模式切换到传输加热模式。 该方法还包括自动变速器油温调节模式,包括测量自动变速器油温度,并根据测量温度在冷却模式和加热模式之间切换。
