Abstract

PURPOSE:To facilitate the control of variable gain by providing a nonlinear transmitting element on the output shaft of a motor type or a negative pressure type actuator and approximating the operation gain characteristic of said actuator to the gain characteristic of a vehicle. CONSTITUTION:A nonlinear transmitting element 1a is provided on the output shaft of a motor type actuator 1, thereby, converting the rotation of a motor into a linear motion, while its value is nonlinearly accelerated or decelerated to be varied to the driving speed (gain) of the actuator 1. The output of this nonlinear transmitting element 1a is transmitted to a throttle valve 6 via a wire 3a and a throttle link 5a. In this case, the operation gain characteristic of the actuator 1 is approximated to the gain characteristic of a vehicle. Also, a throttle link 5b is separately provided on the throttle valve 6 and the operation force of an accelerator pedal 4 is transmitted to this link 5b via a wire 3b.

By the way, each car has its own unique driving ability and responsiveness.For example, sports cars have a little margin in driving ability, and therefore have excellent acceleration performance, and a response speed to the throttle opening (hereinafter referred to as vehicle gain). is set so that it has a linear characteristic 'kW' up to a considerably high speed range, after which it becomes saturated and continues to have a downward characteristic. On the other hand, since the driving capacity and acceleration performance of general passenger cars are lower than those of sports cars, their characteristics are set lower than those of sports cars, and the IJ near range is also set to be quite narrow. In addition, in commercial vehicles, the gain characteristics are set lower than those of the above-mentioned vehicle types in consideration of the large loading weight, and linear characteristics are not necessary, so the gain characteristics are set to have a flat gain characteristic. The gain curve shown in FIG. 8 shows the gain characteristics for each vehicle type.
