摘要： A system for directly measuring tire grip conditions is provided which can measure a skidding condition with no need of applying a vibration. A tire rotation speed sensor comprising a detection gear and a magnet sensor is mounted to a rotating shaft of a tire. An output of the tire rotation speed sensor is analyzed in time-frequency domain to detect vibrations caused by slips, thereby determining tire grip conditions, such as a slip ratio and a slip angle. By detecting fluctuations in rotation based on the cause-effect relation between the occurrence of tire slips and the occurrence of fluctuations in rotation, the tire slips can be directly detected. Therefore, the tire grip conditions can be confirmed with high accuracy.

摘要： A control system for the internal combustion engine is disclosed, in which the operating conditions (such as vehicle speed) and the control conditions (such as throttle opening degree) of the operating elements of the internal combustion engine are used to determine a resistance index (such as an equivalent gradient) for specifying the driving force corresponding to the operating conditions under the prevailing load conditions. Further, this resistance index data is accumulated, so that the operating elements are controlled on the basis of a target operating condition and a corresponding resistance index.

摘要： An engine controller equipped with a device for judging occurrence of knocking of the engine, having a sensor for sampling a vibration based on an internal pressure vibration arisen in a cylinder of the engine and a knocking detecting means for judging the occurrence of the knocking by obtaining at least two frequencies contained in an output from the sensor, obtaining a knocking judgement index from two vibration power factors corresponding to the two frequencies and comparing the knocking judgement index with a threshold value. As being judged from the knocking judgement index, the occurrence of the knocking is accurately detected when the background vibration is great at the time of the high load high speed operation.
