Añado a este hilo un siempre interesantísimo video de Weber Auto.
En esta ocasión muestra el despiece y funcionamiento del transeje P710 del Toyota Rav4. P711 en Corolla 180h y P610 en Corolla 125h aunque todo lo que comenta es aplicable a nuestros Corolla y muy interesante porque toca muchos de los temas debatidos en este foro:
- Porqué la velocidad máxima limitada en los híbridos de Toyota/Lexus.
- Funcionamiento del bloqueo de parking
- Funcionamiento del eCVT
- Modos de funcionamiento del sistema híbrido.
...y mucho más.
Dejo aquí todo el listado (incluido en la descripción del vídeo)
* Esta en inglés pero podéis activar los subtítulos en español.

2:40 Counter driven gear and pinion gear
3:24 Final drive ring gear and differential
4:40 Overall gear ratio MG2 to Tires
6:00 MG2 Power, Torque, and RPM Ratings
7:02 MG2 motor and generator operation
8:00 MUST SEE Two Torque Paths to drive the vehicle
8:19 MG1 and the Power Split Device planetary gear set
8:50 Planetary gear set components
10:30 Ring gear connects to counter drive gear
11:25 Planet carrier connected to the ICE crankshaft
11:45 Sun gear connects to the MG1 rotor
12:01 Oil pump drive shaft
13:10 MG1 rotates the crankshaft to allow the ICE to start
13:40 Parking gear
14:23 MG1 has three functions
17:00 Underdrive, direct drive, and overdrive
18:00 The nine modes of operation of the electronic continuously variable transmission (eCVT)
18:46 Mode 1 "Ready" on with the vehicle stopped
19:28 Mode 2 Charging the high voltage (HV) battery with the vehicle stopped
20:39 Mode 3 Starting off and low-speed cruising on electric power only (EV Mode)
21:36 Mode 4 Starting off and low-speed cruising with a low SOC
22:25 Mode 5 Constant speed cruising (eCVT) operation
23:00 MUST SEE See the ICE RPM, power, and torque ranges for maximum ICE brake thermal efficiency (BTE)
