| 摘要： | In todays environment-conscious world, increasing levels of automotive emissions have been recognized as a major source of pollutants and greenhouse gases. Despite increasingly stringent tailpipe emission standards, the increased use of the automobile has more than offset the lowered per-vehicle emissions. Consequently, there is a great deal of interest in so-called zero-emission vehicles, such as electric and hybrid-electric automobiles. Although very attractive in terms of emissions, these vehicle present some design challenges which are not generally part of conventional automotive design. One such challenge is the development of an effective energy management strategy for the vehicle. While a conventional automobile has an engine whose power output far exceeds the average vehicle needs, hybrid electric vehicles generally have very limited energy reserves and efficiency in the use of these reserves is paramount if acceptable overall performance is to be achieved. Man aspects of the vehicle design (such as aerodynamics, powertrain design, gross weight, etc.) strongly influence the overall vehicle efficiency. However, the actual performance achieved by any given driver is strongly dependent on his or her driving skills. One way to reduce the effect of differences in driving skills is to provide for automatic accelerator control, permitting the vehicle to be driven in an efficient manner without necessitating extensive driver training. This report describes an accelerator/brake control systems developed for use on the Zia Roadrunner New Mexico Tech`s entry in the 1993 Sunrayce for solar-electric hybrid vehicles. |
