Abstract: A cruise control system for maintaining the speed of a vehicle at a fixed, set speed, comprising an actuator including an electric motor which actuates a speed control member via an electromagnetic clutch. To ensure the capability of the cruise control system to decelerate the vehicle even when it is traveling a steep and long downhill, and the normal operation of the cruise control system becomes inadequate for curbing the excessive increase of the vehicle speed, the electromagnetic clutch is disengaged whereby the speed control member is returned to the position for maximum deceleration. Since the operation of the cruise control system is not canceled even when the vehicle speed is increased substantially beyond the set speed, the cruise control system can readily return to its normal operation even after the vehicle is accelerated from the state of cruise control by stepping on the accelerator pedal, for instance for passing another car.

Abstract: A knocking control system for an internal combustion engine with the inlet valves and exhaust valves having valve timing thereof controlled depending on operating conditions of the engine. It is determined whether or not knocking has occurred in the engine on the basis of a detection parameter indicative of knocking and at least one discrimination parameter. The operation of the engine is controlled by the use of at least one control parameter in response to the determination result. The values of the discrimination and control parameters arfe selected in accordance with the actual valve timing. The detection parameter is a level of vibration of the engine comprising a noise component and a knocking component. It is determined that knocking has occurred when the level of the knocking component is higher than one knocking discrimination level set based on the level of the noise component and the discrimination parameter irrespective of the actual valve timing.
