Abstract

PURPOSE:To make the interface to transfer the set vehicle speed to a fuel feed control device from a constant-speed travel control device unnecessary by using the actual vehicle speed during the constant-speed travel control preceding by the preset time as the set vehicle speed of the fuel feed control device. CONSTITUTION:When a set switch 19 is operated in a constant-speed travel control circuit 11, the actual vehicle speed obtained from the output if a vehicle speed sensor 17 is stored in a memory 111 as the set vehicle speed. An actuator 4 is driven and a throttle valve 5 is controlled so that the actual vehicle speed becomes the set vehicle speed until a signal is inputted from a cancel switch 20. On the other hand, a fuel feed control circuit 12 controls a fuel injection valve 9 based on signals from various sensors 14-16, 18 detecting the operating conditions of an engine 1. If fuel cut conditions are met, the actual vehicle speed at the preset time before the preset conditions stored in the memory 121 of the fuel feed control circuit 12 are met is used as the set vehicle speed.
