Abstract:
A dual stage accelerator pedal spring assembly is provided that allows the transition point between stroke stages to be set, thereby controlling pedal travel within the first stroke stage, and notifies the driver of a critical operating condition, such as a low battery pack level, via a pedal feedback system. The spring assembly, which uses two springs exhibiting different spring force, allows adjustment of the relative positions of the two springs in order to control the transition point between the first and second pedal stroke stages. The change in pedal resistance used to notify the driver of a change in a monitored vehicle characteristic is achieved by preloading one of the springs in the spring assembly.
