Abstract

A powertrain control system is disclosed in which an electronic control unit (ECU) (13) controls a power output actuator (10) to drive a fuelling element (12) of an internal combustion engine (not shown). The ECU (13) receives a signal of demanded power from an accelerator pedal demand potentiometer 915) and signal of required power output characteristic (20, 21) from a range switch (16). The ECU (13) selects the required power output characteristic (20, 21) from memory (14) and applies it to control the power output actuator (10) in relation to the pedal demand signal (25) from the demand potentiometer (15). It is thus possible to select between plural power output characteristics (20, 21) depending on vehicle use or driving conditions.
