PURPOSE:To control speed change state, in the case of a preceding vehicle existing at the time of up-slope running, to be appropriate by inhibiting the control of the specified speed change state at the time of detecting the preceding vehicle or a standing vehicle. CONSTITUTION:In a vehicle detecting means 50, a signal processing part 52 processes the signal received by a receiver 51 so as to recognize a preceding vehicle or a standing vehicle. A control device 40 reads the vehicle speed and throttle opening detected by a speed sensor 12 and a throttle sensor 1, calculates the moving average of throttle opening as well as obtains acceleration from the vehicle speed at the specified time, and on the basis of these, calculates the estimated value of running resistance. The control device 40 performs shifting into the running state of large running resistance using this estimated value, for instance, into the up-slope running judging process, but prior to this, controls up-slope running judging process not to be performed when the existence of the preceding vehicle is detected by the signal from the vehicle detecting means 50. The OD inhibiting action accompanied by judgment can be thereby avoided and the vehicle spacing distance to the preceding vehicle can be maintained in safety. |
