A POWERTRAIN CONTROL SYSTEM

摘要

PCT No. PCT/GB97/00162 Sec. 371 Date Jul. 21, 1998 Sec. 102(e) Date Jul. 21, 1998 PCT Filed Jan. 22, 1997 PCT Pub. No. WO97/27388 PCT Pub. Date Jul. 31, 1997A 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.
