25变速器控制系统输入信号和输出信号变速器控制系统用以下信号作为逻辑控制的输入信号。(1)来自离合器转速传感器(从变速器主轴上获得转速)、位置传感器(包括离合器位置、选挡位置和换挡位置)、车速传感器、制动踏板开关(常开开关)、驾驶人侧车门开关(开/关)和点火开关(确定点火开关的位置及发动机是否起动)等的信号。(2)通过CAN-BUS数据总线传来的汽车其他系统的主要信号,例如发动机转速信号(来自ECM)、制动踏板开关(常闭开关)信号、加速踏板位置传感器信号、发动机转矩信
25 TRANSMISSION CONTROL SYSTEM INPUT SIGNALS AND OUTPUT SIGNALS Transmission control systems use the following signals as logic-controlled input signals. (1) from the clutch speed sensor (from the transmission spindle speed), the position sensor (including the clutch position, the gear position and the shift position), the vehicle speed sensor, brake pedal switch (normally open switch), the driver side door switch (On / off) and ignition switch (determining the position of the ignition switch and whether the engine is started) or the like. (2) The main signals of other car systems coming from the CAN-BUS data bus such as the engine speed signal (from the ECM), the brake pedal switch (normally closed switch) signal, the accelerator pedal position sensor signal, the engine torque signal
