Problems of the block of electronic control and operating signals Entrance and target signals of the AT 722.6 control unit and tire of data exchange of CANTasks The ETC control unit (N15/3) defines the current working parameters of a vehicle and exercises administration of consecutive gear shifting, proceeding from simplicity of switching and movement parameters. Activation of electromagnetic valves of switching is carried out at the command of the ETC control unit (N15/3). The demanded size of pressure is calculated on the basis of entering data and necessary adjustment adjustment of a transferred torque. To processing is exposed the following data arriving from other systems: ME-SFI control unit (N3/10)/CDI (N3/9) · A torque developed by the engine; · Gear shifting; · Emergency operation; · Functioning темпостата; · Activation of system of restriction of speed; · Starter functioning; · Kickdown mode activation (as on models 01.06.02) · Working parameters of the engine. Control unit of the electronic lever of switching (N15/5) · Position of the lever; · Sensor switch of modes of transmission (S16/5); · Sensor switch of activation of the kickdown mode (S16/6) (till 31.05.02) Control unit of antiprobuksovochny system (N47) · Frequency of rotation of wheels; · Torque of brake mechanisms; · Fact of squeezing of a pedal of a foot brake; · Condition of the parking brake. EIS [EZS] control unit (N73) · Condition of contact plugs; · Transmission option. Control panel (А1) · Position of the lever of the selector / the chosen transfer. Control unit of antiprobuksovochny system (N47) · Transmission option; · Information on the chosen transfer. ME-SFI control unit (N3/10)/CDI (N3/9) · A torque developed by the engine; · Emergency operation; · Activation of a mode of movement; · Position of the lever of the R/N selector; · Sensor switch of modes of transmission (S16/5) · Transmission option. |
