SensoDrive is a 5-speed automated manual transmission that was installed on some Citroën and Peugeot models from 2002 to 2009. It combines the functions of automatic and manual transmissions. Under normal circumstances, the gear ratio changes automatically according to the road conditions. The possibility of switching to manual mode allows the driver to control the engine torque better in certain driving situations.
How the SensoDrive works
The SensoDrive is based on a conventional manual gearbox with two shafts with gears mounted on them. The clutch and gear engaging mechanisms, however, are managed electronically by a control unit. At a signal from this unit, one actuator disengages the clutch, while the second moves the synchromesh to engage the corresponding gear. In manual mode, information about the gear selected by the driver is supplied to the control unit, which then sends a corresponding signal to the actuators. To change gear, the driver moves the gear lever on the central console to the “+” or “-” position, or uses the paddles behind the steering wheel.
