Moreover, as the energy of our earth being consuming, the environments being worse, humanity believe that they must save the world and save ourselves through some measurements. So different field people do their best to save energy and reduce the damage to the environment. So people working at automotive now are working not only at the fortability for consumers, but also at the saving energy, sustainable development, less polluting. I listen to lecture form Nissan, getting some information as follow. The history of the automobile begins as early as 1769, with the creation of steampowered automobiles capable of human transport. In 1806, the first cars powered by internal bustion engines running on fuel gas appeared, which led to the introduction in 1885 of the ubiquitous modern gasoline or petrolfueled internal bustion engine. Cars powered by electricity briefly appeared at the turn of the 20th century but largely disappeared from monality until the turn of the 21st century, when interest in low and zeroemissions transportation was reignited. And I learned some imagines for automotive. Potential future car technologies include new energy sources and materials, which are being developed in order to make automobiles more sustainable, safer, more energy efficient, or less polluting. Cars are being developed in many different ways. With rising gas prices, the future of cars is leaning towards fuel efficiency, energy savers, hybrid vehicles, battery electric vehicle and the fuel cell vehicle. Being autodriving, the cars do not need people to drive them by himself/herself, and no matter the driver is an older or a kid. And each family will own just one car. With only one dirver`s seat. Then the cars can be designed with less materials. So we can know that how important are strategies of one automotive cooperation. What should they do to have a better petition in future? I have some ments. First one also the most important is the talented personnel. From old times, technology has being the driving force for humanity to make progress with nature and history. And talent people drive technology going ahead. The professional standards of industrial psychologists require that any selection system be based on a job analysis to ensure that the selection criteria are jobrelated. The requirements for a selection system are knowledge, skills, ability, and other characteristics, known as KS
