Dual stage accelerator assembly with pedal feedback system
Abstract:
A dual stage accelerator pedal assembly is provided that is capable of communicating various vehicle operating conditions to the driver as well as notifying the driver of a critical operating condition, such as a low battery pack level, via a change in pedal resistance. The change in pedal resistance is achieved by preloading one of the springs in the accelerator pedal's spring assembly. The spring assembly uses two springs exhibiting different spring force to achieve distinguishable first and second pedal stroke stages.
