摘要: An accelerator pedal assembly (12) for electronically controlling a vehicle engine throttle includes a housing (18), a pedal arm (16) pivotally supported with respect to the housing (18), and a pedal pad (14) connected to a lower end (20) of the pedal arm (16). The pedal arm (16) is pivotable between an idle position and a maximum applied position as a pedal force is applied to the pedal pad (14). Under certain conditions, the accelerator pedal arm (16) can be pivoted to a position that causes the automatic transmission (40) to kickdown by changing to a next lower gear. Under these conditions a feel is imparted to the driver's foot indicating that a downshift has occurred. To simulate this feel in a drive-by-wire application, the pedal arm (16) presents a cam surface (48) for interacting with a spring (50) that has a first end (52) seated within the housing (18) and a movable second end (54) for bias engagement with the pedal arm (16). The spring (50) includes a roller (60) mounted on the second end (54) that is forced into contact with a lobe (74) on the cam surface (48) when the pedal arm (16) is pivoted from a first operable position to a pre-determined kickdown position. As the roller (60) engages the lobe (74), the pedal force required to further pivot the pedal arm (16) is increased imparting a kickdown feel to the driver via the pedal pad (14).

摘要: A pedal assembly is characterized by a shipping connection, generally shown at (18), interconnecting the pedal arm (12) and the pedal platform (16) for pivoting the platform (16) to a shipping position (as shown in FIG. 7) generally overlying the pedal arm (12) and for pivoting to and locking the platform (16) in a locked position extending generally in the same direction and as an extension of the pedal arm (12) (as shown in FIGS. 1-3) for the normal operational pivotal movement about the operational axis. A locking pin (22) includes a beveled end (36) projecting into the space between the legs of the pedal platform (16) for engaging the arm (12) and calming the locking pin (22) out of the locked position during movement of the pedal platform (16) from the shipping position to the locked position.

摘要: A pedal assembly (12) for electronically controlling an engine throttle (38). The pedal assembly (12) includes a pedal housing (14), a pedal arm (18) pivotally engaging the pedal housing (14), and an electrical generator (30) supported by the pedal housing (14). The pedal arm (18) is operable between an idle position (24) and a plurality of operable positions. When the pedal arm (18) is pivoted to a predetermined operable position (50), a kickdown member (46) provides a kickdown feel to a user. Simultaneously, the electrical generator (30) generates a control signal having a predetermined magnitude causing the automatic transmission (42) to downshift to a next lower gear. The kickdown member (46) is adjustable to synchronize the kickdown feel provided by the kickdown member (46) with the downshift to the next lower gear.
