Title:
THROTTLE DRIVING DEVICE
Document Type and Number:
Japanese Patent JPH01110849
Kind Code:
A
Abstract:
PURPOSE:To smoothen the acceleration at a low speed stage by setting the opening degree of a throttle valve for the accelerator operation quantity having the revolution speed as parameter so that the variation of the shaft torque is reduced in correspondence with the variation of the revolution speed as the speed change stage becomes lower. CONSTITUTION:Each detection value of an accelerator operating quantity detecting sensor 3, revolution speed detecting sensor 4, and a speed change state detecting sensor 5 is inputted into a computer 6, and the opening degree of a throttle valve 1 is controlled through a stepping motor 2. In a ROM 6c, the relation between the accelerator operation quantity having the revolution speed as parameter and the throttle opening degree is memorized in a two dimension map for each speed change stage of a transmission 9. In this two dimension map, the variation of the shaft torque generated in correspondence with the variation of the revolution speed in a region having a small accelerator operation quantity is set to a small value so that the variation of the shaft torque generated in correspondence with the variation of the revolution speed with an equal accelerator operation quantity is reduced in a low speed stage.
