51412.全球汽车被动安全系统市场报告（2015-2019年）
[汽车制造业] [2015-05-11]
Automotive safety systems are designed and produced to comply with standards and regulations prescribed by government agencies and transport authorities across the world. Passive safety systems such as airbags and seatbelts are designed to protect passengers, drivers, and pedestrians during an accident. With growing safety concerns among consumers and increase in road fatalities, government agencies and organizations such Euro NCAP, US NCAP, and India NCAP are mandating the inclusion of airbags in all new automobiles.

51413.印度农业轮胎市场报告（2015-2019年）
[橡胶和塑料制品业,汽车制造业] [2015-05-11]
Tires track their history back to the mid-1800s when solid tires were more prevalent. With time and new advances, solid tires were replaced by pneumatic tires, which were first used on automobiles by the Michelin brothers, who went on to become one of the prominent tire vendors in Europe.Over time, the tire market has witnessed new technology breakthroughs and the entry of many vendors.

51414.欧洲重型卡车市场报告（2015-2019年）
[汽车制造业] [2015-05-11]
Trucks are of several types: Light duty trucks, medium duty trucks, and heavy duty trucks. Heavy duty trucks, as the name implies, are used for heavy duty work, such as loading or pick-up and concrete mixer applications used in construction activities. These trucks have a GVWR of more than 26,000 lb. But, in terms of mileage and fuel emissions, the fuel economy of heavy duty trucks remains a concern among consumers and the governments in Europe. However, with the economic benefits of natural gas, the market will see a drift toward the usage of natural gaspowered trucks in the years to come.

51415.全球混合动力汽车市场报告（2015-2019年）
[汽车制造业] [2015-05-11]
HEVs combine two energy sources, mechanical (ICE) and electrical, to achieve better fuel economy and performance. These vehicles have a smaller gasoline engine than traditional vehicles. They use efficient technologies such as regenerative braking that charges the battery by converting kinetic energy into electric energy. Many HEVs have start-stop systems that shutdown the ICE when the vehicle is idle and restarts it whenever needed, thereby reducing idle emissions.

51416.美国电动汽车（EV）市场报告（2015-2019年）
[汽车制造业] [2015-05-11]
An EV is an automobile that is powered by an electric motor using electric energy stored in the batteries or any other energy storage device. These vehicles offer advantages by being environmental friendly and energy efficient. The US is considered one of the main consumers of EVs. Because of rising environmental concerns and increasing greenhouse gas emissions, the benefits provided by various states governments for consumers (California, Georgia, New Jersey, and Illinois) have increased, in turn increasing demand and adoption of EVs.

51417.复合功率分流混合电动轿车驱动模式切换的协调控制
[汽车制造业] [2015-05-10]
为对带双行星排复合功率分流的混合动力轿车驱动模式切换过程中的转矩进行协调控制,采用基于转矩解耦的控制方法来求解不同切换阶段动力源的目标转矩。在此基础上,针对切换过程中输出端转矩波动和发动机实际转矩难以精确确定等问题,提出了基于发动机转矩估计和电机转矩补偿的模式切换协调控制策略,并在Matlab/Simulink软件平台下进行仿真验证。结果表明,该协调控制策略能有效降低切换过程中输出端的转矩波动和整车的冲击度。

51420.驾驶员侧50%假人约束系统配置5%女性假人伤害研究
[汽车制造业] [2015-05-10]
在L车型开发后,进行了3次正面碰撞试验,对基于50%假人开发的约束系统对5%假人的保护效果进行了研究。3次正面碰撞试验分别为驾驶员侧分别为50%假人和5%假人,安全气囊和安全带预紧功能正常起爆;驾驶员侧为5%假人,但安全气囊和预紧功能不起爆。研究结果表明,基于50%假人开发的约束系统,对5%假人的头部和胸部依然具有较好的保护作用,但对5%假人的颈部伤害较重,可通过对安全气囊分级起爆、调整拉带设计等方法进行优化;安全气囊不起爆方法不可取。
