Abstract
A change amount .DELTA.TVO is computed as a deviation of a new value for the throttle opening representing engine load from a previous value. When the change amount .DELTA.TVO is greater than or equal to a positive judgment level TH and engine load is changing rapidly in an increasing direction, computation of running resistance using a detected value for the throttle opening is stopped. However, since when the throttle opening is stable or the throttle opening is changing reducingly, a necessary and sufficient computational accuracy can be maintained, computation of the running resistance is not stopped, and control is carried out based on the computational results.
