<p>PROBLEM TO BE SOLVED: To perform traction control according to a state, in a wheel slip control device to perform detection of an bad road and detection of noise simultaneously with each other. SOLUTION: Since, when it is decided at S3 that an bad road flag is set, it is not decided whether noise flag is set and control coping with an bad road is performed at S7. Namely, since, when an bad road flag is set, even when noise flag is set, control coping with an bad road is effected, it is detected that a car is in a state to run on an bad road, when it is detected that it is in a state to run on an bad road and it is detected that noise is generated, control coping with an bad road is effected. Noise is generated in a sporadic manner and reliability on a detecting result that a car is in a state to run on an bad road is higher than that on a detection result that noise is generated. Thereby, when the two results are detected, slip control according to a state is practicable through control coping with an bad road.</p> |
