Abstract
The vehicle described herein employs an electronic control unit (“ECU”) and/or accessory control module configured to improve actual fuel, economy. The ECU and/or the accessory control module monitors vehicle operating conditions and reduces load from an accessory when the vehicle achieves predetermined operating conditions. The ECU and/or the accessory control module is also configured to engage a fuel cut and a torque converter lock up condition. The lock up condition causes the wheels to drive the motor to avoid engine stall. At a predetermined low level, the ECU and/or the accessory control module can re-engage the accessory and fuel supply and disengage the lock up condition.
