 An array of sensors continuously monitored six parameters and, using "fuzzy logic", adapted the shift patterns in the automatic gearbox "on the fly" according to the driver's style.The four-wheel drive, four-wheel steering, traction control system and suspension were all similarly adapted based on the same sensor data.INVECS would, for example, downshift to increase engine braking while travelling downhill, or similarly automate transmission processes which were previously only controlled manually by the driver.
