The general principles of functioning of system the transmission, operating signals

General information

Scheme/design of an arrangement of the main components of an electronic control system by transmission and an ID card of plugs of the AT 13-contact socket are presented on illustrations.

Scheme of an arrangement of components of an electronic control system of AT

N15/3 — the Module of management of transmission (TCM)
S16/6 — the Sensor switch of activation of the kickdown mode

Y3/6 — Electric knot of the electrohydraulic control unit switchings

Design of the electrohydraulic control unit switchings

2а — the Hydraulic block
11 — the 13-contact socket
Y3/6 — the Electric control unit switchings
Y3/6b1 — the Sensor of temperature of ATF
Y3/6n2 — the Sensor of 2 turns
Y3/6n3 — the Sensor of 3 turns
Y3/6s3 — Contact of blocking of start

Y3/6y1 — Ø/m the valve of management of pressure modulations
Y3/6y2 — Ø/m the valve of management of pressure of switchings
Y3/6y3 — Ø/m the valve of management of switchings 1-2 and 4-5
Y3/6y4 — Ø/m the valve of management of switching 3-4
Y3/6y5 — Ø/m the valve of management of switching 2-3
Y3/6y6 — Ø/m the ShIM valve of blocking of the hydrotransformer

Design of the selector module (without function of a consecutive choice of ranges, - release models till 31.08.99)

Card of identification of plugs of the 13-contact socket of the electrohydraulic control unit switchings

1 — the Sensor of 3 turns (Y3/6n3)
2 — Э / the magnetic valve of adjustment of modulating pressure (Y3/6y1)
3 — the Sensor of 2 turns (Y3/6n2)
4 — the Entrance signal of the sensor of temperature (Y3/6b1) and contact of blocking of a starter (Y3/6s1)
6 — Supply voltage э / magnetic valves
7 — sensor Supply voltage

8 — Э / the magnetic valve of gear shifting of 2-3 (Y3/6y5)
9 — Э / the magnetic valve of gear shifting of 3-4 (Y3/6y4)
10 — Э / the magnetic valve of adjustment of pressure of switching (Y3/6y2)
11 — Э / the magnetic valve (blocking of the converter of rotation) (Y3/6y6)
12 — the sensor Case
13 — Э / the magnetic valve of gear shifting of 1-2/4-5 (Y3/6y3)

TCM (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.
