摘要： PURPOSE:To perform the constant speed smoothly, by the constitution that the operating means of the speed adjusting element follows to the element before the constant speed running and the element is driven with the conrol signal from the control means after the constant speed running starts. CONSTITUTION:When the vehicle starts running, the opening of the throttle valve 12 has a value in response to the acceleration pedal 25 and the operating means AC is not operated at this time. On the other hand, the speed signal from the speed sensor 30 in response to the car speed is given to the timing signal generating circuit 130. The circuit 130 gives the signal corresponding to car speed to the control signal generating circuit 140, vehicle speed set circuit 160, vehicle speed difference detecting circuit 170, and acceleration detecting circuit 180. With this condition, when the vehicle reaches the desired set speed and the set switch 40 is closed, the set signal (c) is generated and given to the circuit 140. The circuit 140 gives the required signal to each circuit in the electronic control circuit EC in accordance with the signal (c). Thus, the circuit EC controls the means AC, which controls the opening of the valve 12 to keep the desired constant speed state for the vehicle.

摘要： PURPOSE:To constantly control the speed despite the speed of the car by changing the opening of a throttle valve corresponding to the acceleration detected by the change in the running speed and the speed difference between the running speed and the setting speed. CONSTITUTION:The control device is constituted of an actuator AC to operate a throttle valve 12 and an electron control circuit EC to control the actuator AC. EC is equipped with a circuit 130 to generate timing signals responding to the running speed of a vehicle by receiving the output from a speed sensor 30, a clock signal generator 110, and a setting circuit 160 which generates the setting speed signal to run the vehicle at the desired constant speed. Also equipped are a speed detecting circuit 170 to generate the speed difference signals and an acceleration detecting circuit 180 to generate acceleration signal. When the acceleration shows the positive signs by comparing said acceleration and speed defference with the fixed value, the throttle valve 12 is controlled in closed direction through AC.

摘要： PURPOSE:To prevent the generation of knocking for sure in the succeeding combustion after detecting a knocking once by giving a greater angle of delay in the detection of knocking in comparison with the angle of lead when no knocking is given. CONSTITUTION:A discrmination circuit 20 outputs a knocking signal to an ignition angle setting circuit 21, which gives a subtraction to the ignition timing synchronous ly with the number of engine revolutions and prevents knocking in an engine 1 by reducing the angle of lead to delay the ignition timing. When knocking is prevented in the engine 1, the ignition angle setting circuit 21 advances the ignition timing. As this course of action is repeated, in the result, the ignition timing of the engine 1 is controlled by feedback in a timing of knocking limitation, that is, in the nearest timing to MBT without knocking, and the engine 1 is driven with a sufficient torque.
