ABSTRACT:
An apparatus for controlling speed of a vehicle to consist with a target speed in cruising mode, the vehicle having power transmission for selecting a gear ratio from plural predetermined gear ratios comprising: detector means for detecting the speed; and controller: for producing a first control signal for effecting downshifting to high when the speed decreases under the target speed; for detecting increase rate of the speed in response to the first control signal; and for producing a second control signal for effecting upshifting in response to said first control signal with delay determined by the increase rate. A negative pressure pump may be further provided for driving a negative pressure actuator controlling a throttle valve, the pump is turned on when the speed decreases under a given value before detection of lack of negative pressure downstream from a throttle valve, for driving negative pressure actuator controlling the throttle valve. A fail-safe system may be further provided which detects excessive flow rate of air-fuel mixture due to trouble at the negative pressure actuator in cruising mode for preventing unintentional and rapid acceleration.
