Abstract
A system for overriding a vehicle speed limit setting via accelerator pedal override is disclosed, comprising a vehicle including steering, an accelerator pedal, brakes, a processor, and memory, and a vehicle speed limit override module coupled to the processor and configured to override the speed limit setting by calculating an override threshold based on the set speed limit and accounting for variable vehicle weight, road grade or other unknown loads.

A system for overriding a vehicle speed limit setting via accelerator pedal override, comprising:
- a vehicle including steering, an accelerator pedal, brakes, a processor, and memory;
- a vehicle speed limit override module coupled to the processor and configured to override the speed limit setting by calculating an override threshold based on the set speed limit and accounting for variable vehicle weight, road grade or other unknown loads.
A system for overriding a vehicle speed limit setting via accelerator pedal override, comprising:
- a vehicle including steering, an accelerator pedal, brakes, a processor, and memory;
- a vehicle speed limit override module coupled to the processor and configured to rescale a pedal override position to 50% of a total available rescaled pedal travel after initiation of pedal override of the speed limit setting to compensate accelerator pedal travel range.
A system for overriding a vehicle speed limit setting via accelerator pedal override, comprising:
- a vehicle including steering, an accelerator pedal, brakes, a processor, and memory;
- a vehicle speed limit override module coupled to the processor and configured to rescale a pedal override position to 50% of a total available rescaled pedal travel after initiation of pedal override of the speed limit setting to compensate accelerator pedal travel range, wherein vehicle acceleration smoothly transitions from speed limiting to vehicle acceleration after initiation of pedal override.
