摘要： A method for computing a current vehicle speed value from a detected vehicle speed value derived from a pulse signal, said method provided data which can be used in a control process such as a cruise control of a vehicle, in which the current vehicle speed value is predicted from a previously computed vehicle speed value after an abnormal state of the current detected vehicle speed value is detected; and a cancel signal is produced for aborting the control process when the abnormal state has persisted for more than a certain time period. Thus, the derivation of an abnormal computed vehicle speed value is prevented when a temporary abnormal condition of the detected vehicle speed value has occurred, and a cancel signal, which may be used for aborting the operation of the control process, is produced when the abnormal condition of the detected vehicle speed has persisted for more than a certain time period, whereby the control system can respond to the abnormal conditions of the detected vehicle speed value in optimal fashion, and convenience and safety are both maximized.

摘要： A vehicle cruise control system, comprising a control circuit for producing a control signal for maintaining a speed of a vehicle at a fixed level according to a difference between an actual vehicle speed and a target vehicle speed, and a drive circuit for producing a drive signal for selectively driving an actuator in a direction either to accelerate the vehicle or to decelerate the vehicle according to the control signal from the control circuit. The drive circuit is provided with a transistor bridge circuit comprising four drive transistors for producing the drive signal. The control circuit is provided with a detection means for detecting an abnormal state of the system and an inhibiting means which brings at least one of the drive transistors into an non-conductive state when any abnormal state is detected by the detecting means. The control circuit may be programmed to perform a certain diagnostic procedure for testing the soundness of the drive transistors. Thus, erratic behavior of the cruise control system and destruction of the drive transistors can be effectively prevented.

摘要： A pseudo-random number generator 100 generates a pseudo-random number by the following operation. At C.2, S1[B41] is determined from B41 set in a second internal memory, and S2[B40] is determined from B40. Then, R[J] is generated from S1[I], S1[B41], and S2[B40]. At C.3, S1[I] is newly generated based on S1[B41] and S2[B40]. At C.4, B4 is updated from S2(I). In the above, the relationship between R[J] and S2(I) is cut off, which makes difficult to estimate S2(I) from R[J], and security is increased. Further, since S1[I], S1[B41], S2[B40], etc. have 4 bytes, the processing speed is high.
