摘要： A vehicle constant speed control system including a vehicle speed detector and a controller for controlling the engine throttle valve so that the engine output is controlled to make the vehicle speed approach a target speed. The controller compares the actual vehicle speed with the target speed and calculates a required driving torque for driving the vehicle at the target speed and a target throttle valve position which is required for producing the required driving torque. The controller then produces a driving signal to actuate the engine throttle valve so that the required driving torque is produced and the target speed is attained.

摘要： Engine throttle valve control device having a step motor to operate a throttle valve which comprises detecting means for detecting the need for changing the rotational direction of the step motor, and delaying means which delays the supply of the drive signal to the step motor for a predetermined period when the need for changing the rotational direction of the step motor is detected by the detecting means. In the present invention, when it is necessary to change the rotational direction of the step motor, the step motor is not immediately driven to reverse the rotational direction but is halted for a predetermined short time. After the short time passes the step motor is driven to rotate in the opposite direction. According to the present invention, the inertial force acting on the step motor when it changes its rotational direction can be avoided or decreased. Hence, loss of control of the step motor due to the inertial force is avoided, and accurate control of the throttle valve opening is performed.

摘要： First, second and third levers are disposed pivotably and rotatably relative to each other about a predetermined axis. The first lever is operated in association with an accelerator to be rotated in a predetermined one direction in accordance with operation in a direction of opening the accelerator. The second lever is operated in association with a throttle valve so as to open the throttle valve when the second levler is pivotted in the predetermined one direction and it is urged by a first urging member in a direction of closing the throttle valve. The first lever is provided with a first stopper section and the second lever is provided with a second stopper section as to be abuttable with the first stopper section from the predetermined one direction. The first stopper section is urged in such a manner as being brought into abut with the second stopper section by means of a second urging member larger in an urging force than the first urging member. The second lever is forcibly pivotted in the same direction as the third lever in resistance to the second urging member when the third lever is pivotted in a direction opposite to the predetermined one direction by a motor.
