Features of the hydromechanical gearbox type 01

On fig. 4-58 shows the details of an automatic transmission type 01 M. The electronic control unit is installed on cars with engines 2E, ABS, 1Z, AFN of release from January 1995 and engine 2E of release from June 1996. The electronic control unit of the hydromechanical gearbox issues commands to the electromagnetic control valves of the valve box, generated on the basis of information received from the vehicle speed sensor, the transmission speed sensor, the engine crankshaft speed sensor through the integrated engine management system controller, from the potentiometric accelerator pedal position sensor (which includes a switch for the forced reverse gear changeover system «kickdown»), from the transmission oil temperature sensor, brake light switch and multi-function sensor (pic. 4-51).






Depending on the information received, the control unit issues commands to the solenoid valves of the valve box (pic. 4-52), electromagnetic selector lever lock (with the ignition on) and starter interlock relay (in any gear).



The control unit works according to fuzzy logic (or with deliberate inaccuracy), i.e. taking into account all intermediate states that occur between the main states (0-1 in binary logic).

Thanks to this, the operation of the hydromechanical gearbox adapts to the driving style. engine characteristics and driving conditions (wheel rolling resistance). Gearbox has no «economical» and «sports» operating modes.

Electronic control unit 68-valve.

Applicability of gearbox types and their gear ratios are shown in tables 4-7 and 4-8.
