Pneumatic accelerator pedal actuator

摘要

A vehicle accelerator pedal actuator may include a pressurized fluid source, a mounting mechanism configured to fix the accelerator pedal actuator relative to a vehicle accelerator pedal, and an actuating mechanism in fluid communication with the pressurized fluid source and configured to displace the vehicle accelerator pedal. The vehicle accelerator pedal actuator may further include a valve member selectively controlling fluid communication between the pressurized fluid source and the actuating mechanism.

1. A vehicle accelerator pedal actuator, comprising:
a body; a first chamber formed within the body; a first actuating member having a first portion located within the first chamber and a second portion located outside of the first chamber and the body; a first biasing member located within the first chamber, the first biasing member configured to bias the first actuating member to a first position within the first chamber, wherein, in the first position, the second portion of the first actuating member is configured to unclamp a brake pedal from the body; a second chamber formed within the body; a second actuating member having a first portion located within the second chamber and a second portion located outside of the second chamber and the body; a second biasing member located within the second chamber, the second biasing member configured to bias the second actuating member to a second position within the first chamber, wherein, in the second position, the second portion of the second actuating member is configured to release an accelerator pedal; a pressurized fluid source; a first valve configured to selectively provide fluid, pressurized from the fluid source, against the first portion of the first actuating member to force the first portion of the first actuating member to a third position within the first chamber, and against the first biasing member, to cause the second portion of the first actuating member to clamp the brake pedal to the body; and a second valve configured to selectively provide the fluid against the first portion of the second actuating member to force the first portion of the second actuating member to a fourth position within the second chamber, and against the first biasing member, to cause the second portion of the second actuating member to depress the accelerator pedal.
