Abstract: PURPOSE:To control speed change state, in the case of a preceding vehicle existing at the time of up-slope running, to be appropriate by inhibiting the control of the specified speed change state at the time of detecting the preceding vehicle or a standing vehicle. CONSTITUTION:In a vehicle detecting means 50, a signal processing part 52 processes the signal received by a receiver 51 so as to recognize a preceding vehicle or a standing vehicle. A control device 40 reads the vehicle speed and throttle opening detected by a speed sensor 12 and a throttle sensor 1, calculates the moving average of throttle opening as well as obtains acceleration from the vehicle speed at the specified time, and on the basis of these, calculates the estimated value of running resistance. The control device 40 performs shifting into the running state of large running resistance using this estimated value, for instance, into the up-slope running judging process, but prior to this, controls up-slope running judging process not to be performed when the existence of the preceding vehicle is detected by the signal from the vehicle detecting means 50. The OD inhibiting action accompanied by judgment can be thereby avoided and the vehicle spacing distance to the preceding vehicle can be maintained in safety.

Filed: 1983-07-01
Abstract: PURPOSE:To form a multi-phase clock guaranteeing non-overlap by connecting a course making the reset of another latch circuit precede to a positive feedback loop of a latch circuit constituted by two gate circuits. CONSTITUTION:Two NOR gate circuits G1-G8 are connected to a latch format. If an input signal B is ''1'' when only an output signal phi1 from the circuit G2 is ''1'' and signals phi2-phi4 are ''0'', an output signal from the circuit G3 becomes ''0''. The output signal is turned to ''1'' through an inverter IV2 and supplied to the circuits G2, G6, G8 and ''0'' signals are outputted to the respective circuits G2, G6, G8, so that the output phi1 of the circuit G2 is turned to ''1''. Consequently, the inputs of the circuit G1 are both ''0'' and the output signal is ''1''. A ''0'' signal is transmitted to the circuit G4 through an inverter IV1. Since a signal from another latch circuit to the circuit G4 is also ''0'', the output signal phi2 of the circuit G4 is turned to ''1'' after a prescribed period from the time when the signal phi1 has been turned to ''0''.
