摘要： A vehicle running control device capable of smoothly and constantly stopping a driving vehicle at the same vehicle-to-vehicle distance every time a preceding vehicle stops to give occupants a feel of safe, comprising a means for detecting the speed of a preceding vehicle, a means for detecting the distance between a driving vehicle and a preceding vehicle, a first target distance setting means to be set when the preceding vehicle is running at a speed higher than a preset speed and a second target distance setting means to be set when it is running at a speed lower than the preset speed, thereby controlling the driving vehicle by selecting between a first target vehicle-to-vehicle distance and a second one.

摘要： An object of the present invention is to provide an abnormality diagnostic system that can enhance diagnostic precision even if a computer arranged on the machine side does not have sufficient throughput in diagnosing a condition of a machine or equipment based upon time series data generated by a sensor and can reduce communication capacity because communication data volume decreases and industrial machinery provided with the abnormality diagnostic system. A diagnostic device on the machine side 2 diagnoses time series data generated by a sensor, acquires a primary diagnostic result, extracts time series data related to the primary diagnostic result and outputs it to a diagnostic device on the server side 3 together with the primary diagnostic result, the diagnostic device on the server side 3 diagnoses the time series data, acquires a secondary diagnostic result, and displays the secondary diagnostic result together with the primary diagnostic result. Besides, the diagnostic device on the server side compares the diagnostic results and updates a diagnostic process of the diagnostic device on the machine side 2 when the diagnostic results are different as a result of the comparison.

摘要： A vehicle which has a first running mode in which the frontward running environment of the vehicle is recognized and at least one of the engine, change gear, and brake of the vehicle is controlled based on the recognizing signal and a second running mode in which at least one of the engine, change gear, and brake is controlled based on a signal generated by the driver of the vehicle, and which is adapted to select the second running mode in such an area that the follow-up control of the vehicle is difficult.
