Title:
DUAL RADIUS GEOMETRY ACCELERATOR CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/1995/027240
Kind Code:
A1
Abstract:
A dual radius geometry accelerator control system is provided on which the throttle valve (14) is made to open at various rate during the operation. This unique throttle valve actuation scheme is achieved through an inventive control member (16) with a dual radius design for opening the throttle valve (14) at a non-linear actuation rate in response to the linear travel of the accelerator cable (26) and guiding pin (34) connected to the control member (16) for contacting the accelerator cable (26) such that, in a first range (40) of accelerator pedal actuation, the accelerator cable (26) contacts the guiding pin (34) at an engagement point (36) to open the throttle valve (14) at a first continuously changing actuation rate that reaches a maximum system value at a cross-over point (46), and in a second phase of accelerator pedal actuation (50), the accelerator cable (26) pulls the control member (16) from a pull point (48) to open the throttle valve (14) at a second continuously changing actuation rate that has a local minimum value.
