Dual stage accelerator assembly with selectable stroke transition

A dual stage vehicle pedal accelerator assembly, comprising:

• an accelerator pedal;
• and
• a first spring assembly, wherein an accelerator linkage arm couples said accelerator pedal to said first spring assembly, said first spring assembly comprising:
• a first spring;
• a second spring assembly comprised of a second spring and a rear spring support member proximate to a second end of said second spring, wherein a position of said second spring assembly relative to said first spring determines a transition point between a first pedal stroke stage and a second pedal stroke stage;
• a first spring compression member coupled to said accelerator linkage arm and proximate to a first end of said first spring, wherein during an initial stage of accelerator pedal travel corresponding to said first pedal stroke stage said first spring compression member only compresses said first spring, and wherein during a final stage of accelerator pedal travel corresponding to said second pedal stroke stage said first spring compression member compresses both said first spring and said second spring;
• an adjustment mechanism coupled to said rear spring support member, wherein upon receipt of a first control signal said adjustment mechanism is configured to move said second spring assembly to a first position relative to said first spring, and wherein upon receipt of a second control signal said adjustment mechanism is configured to move said second spring assembly to a second position relative to said first spring, wherein said first pedal stroke stage is shorter when said second spring assembly is in said second position compared to said first position;
• and
• a stage transition controller coupled to said adjustment mechanism, said stage transition controller configured to transmit said first and second control signals to said adjustment mechanism.
