Abstract

Hybrid vehicle design circuitry quantifies values for utility/disutility variables of a hybrid vehicle design by evaluating a hybrid vehicle model over a collection of drive cycles/routes. The utility/disutility values include at least one of: total time or additional time beyond a reference time needed for the hybrid vehicle design to complete the drive cycles/routes, a fraction or number of the drive cycles/routes for which the hybrid vehicle design fails to achieve a target velocity, and amount of time or distance over which the hybrid vehicle design fails to achieve a target acceleration or the target velocity over the drive cycles/routes. The hybrid vehicle design circuitry calculates one or more specifications of a hybrid vehicle design based on the utility/disutility values.
