Abstract
A low profile electronic throttle pedal assembly for vehicles includes a base plate mounted on the floor of the vehicle and a throttle treadle pivotally mounted on the base plate. The treadle includes a lower lever arm portion extending through the base plate into a space beneath the vehicle floor. A throttle position sensor as well as the drive mechanism connecting lever arm with the sensor are both carried on the bottom side of the plate, beneath the vehicle floor. Treadle return springs pass through the plate and are seated beneath the vehicle floor.
Claims20
An electronic throttle pedal assembly of a vehicle, comprising:
- a base mounted on the floor of said vehicle;
- a treadle having an upper portion adapted to be contacted by the operator of said vehicle, and having a lower portion extending downwardly through said floor;
- a first pivotal connection mounting said treadle on said base for pivotal motion about a first axis;
- an electrical sensor for sensing the pivotal position of said treadle and producing an output signal related to the sensed position of said treadle;
- linkage drivingly connecting said lower portion of said treadle with said sensor.
A low profile electronic throttle pedal assembly of a vehicle, comprising:
- a base plate mounted on a floor of said vehicle, said plate having an opening therein providing access to an area beneath said floor;
- a treadle having an upper portion above said plate, and a lower portion extending downwardly through said opening to said area beneath said floor;
- a hinge mounting said treadle for pivotal movement between a closed throttle position and
- a wide open throttle position;
- a sensor mounted beneath said floor for sensing the pivotal position of said treadle and outputting an electrical signal related to the sensed position of said treadle.
An electronic throttle control pedal assembly of a vehicle, comprising:
- a base mounted on a floor of said vehicle and including a lower portion disposed beneath said floor;
- a treadle mounted on said base for pivotal movement between a closed throttle position and a wide open throttle position, said treadle including an upper portion and a lower portion extending downwardly beneath said floor;
- at least one compression spring for biasing said treadle toward said closed throttle position, said spring engaging said upper treadle portion and seated within said lower portion of said base;
- and,
- a position sensor for sensing the position of said treadle and generating an electrical signal indicative of said treadle position.
