1. An apparatus for detecting running resistance of a vehicle comprising:

  • engine load detection means for detecting engine load;

    running resistance computation means for computing vehicle running resistance based on parameters including at least the engine load detected by said engine load detection means, and outputting a signal for the computed running resistance; and

    computation stopping means for stopping computation of the running resistance by said running resistance computation means when there is a rapid change in the engine load detected by said engine load detection means, and the engine load is changing increasingly.
