人机交互系统是信息化技术发展的产物,该系统实现了人与车之间的对话功能,就比如我们常用电脑的windows一样。车主可通过该系统,轻松把握车辆状态信息(油耗、车速、里程、当前位置、车辆保养信息等)、路况信息、定速巡航设置、蓝牙免提设置、空调及音响的设置。

第二代iDrive系统在宝马3系上采用了8. 8英寸高分辨率显示屏,而在7系上显示屏的尺

寸更大。而且屏幕的分辨率达到了1280*480,是三款车型中最高的。实际视觉效果也可看出,宝马的iDrive界面最为清晰美观。

而就在售价49.5万元的宝马325i运动型上,iDrive系统已经具备车载电视和蓝牙免提功能。打开手机的蓝牙功能搜索到自己的宝马,再输入相同的匹配密码就可以将手机与iDrive 相连。

附录 附录A Braking system function is to make the car driving in accordance with the requirements of the pilot required even slow down park; They offend car has in various road conditions (including in the slope stability) in car; Make the downhill cars speed to be stable. For car up the role of brake is only in the car and role with the direction of the car driving direction opposite forces, and the size of these forces are random, do not control, so cars must be installed on a series of special equipment to achieve the function. Automobile brake system is to point to to ensure that the car in technology, improve the safe driving car average speed, etc., and the admiration installed in the car brake special brake institutions. In general automobile brake system including crane brake system and parking brake two sets of independent device. One crane brake device is a driver with feet to manipulate, and it said the foot brake. Parking brake device is a pilot with the hand, so it says of the manipulation of the hand brake. The function of the crane brake system is to make the car slow down or running in the shortest distance parking within. And parking brake function is to make had stopped the car on the road all keep still. But, sometimes, in an emergency, two braking device can be used at the same time and increase the effect of auto brake. Some special purpose of cars and often in the mountains cars, long and frequently brake will lead to crane brake system overheating, so in these cars often add all sorts of different types of auxiliary braking equipment, so as to speed up the hill stability. According to the braking energy situation, brake system can also be divided into human brake system, power brake system, and servo brake system, three. Human brake system to the driver's physical strength as braking energy; Power brake system engine power to the transformation of the air pressure or hydraulic braking energy as; And servo brake system is the most human and engine power as a brake energy. In addition, according to the braking energy transfer mode, brake system and can be divided into mechanical and hydraulic, pneumatic type and assolenoid style wait until a few kinds.

Automobile Brake System The braking system is the most important system in cars. If the brakes fail, the result can be disastrous. Brakes are actually energy conversion devices, which convert the kinetic energy (momentum) of the vehicle into thermal energy (heat).When stepping on the brakes, the driver commands a stopping force ten times as powerful as the force that puts the car in motion. The braking system can exert thousands of pounds of pressure on each of the four brakes. Two complete independent braking systems are used on the car. They are the service brake and the parking brake. The service brake acts to slow, stop, or hold the vehicle during normal driving. They are foot-operated by the driver depressing and releasing the brake pedal. The primary purpose of the parking brake is to hold the vehicle stationary while it is unattended. The parking brake is mechanically operated by when a separate parking brake foot pedal or hand lever is set. The brake system is composed of the following basic c omponents: the “master cylinder” which is located under the hood, and is directly connected to the brake pedal, converts driver foot’s mechanical pressure into hydraulic pressure. Steel “brake lines” and flexible “brake hoses” connect the master cylinder to the cylinders” located at each wheel. Brake fluid, specially designed to work in extreme conditions, fills the system. “Shoes” and “pads” are pushed by cylinders to contact the “drums” and “rotors” thus causing drag, which (hopefully) slows the car. The typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder (Figure).

3款人机交互系统对比

如果说20万以下的一般家用车型之间比拼的是材质的优劣、做工的粗细以及车载配置的多寡的话,那当竞争到达30万甚至40万以上的级别时,在这些基本方面大家做的都已经很好了,高低胜负现在取决于设计的理念、品牌的内涵以及科技的应用上。 而奥迪的MMI、宝马的iDrive以及奔驰的COMAND,这三种效力于不同品牌的人机交互系统恰好正是用科技含量提升豪华品质的代表配置。本文就将为大家展示对比这三种系统的优劣势,看看它们谁对提升产品竞争力更有帮助。 ● 奥迪A4L的MMI——3D地图令人印象深刻没有蓝牙免提有些遗憾

奥迪的MMI多媒体人机交互系统首次出现在2004年,最早装备的车型是当时的奥迪A6。本文以奥迪A4L 2.0T车型上的MMI系统为例进行讲解。这套系统是奥迪装备的第三代MMI,是目前国内车型所使用的最新版本(国外的最新版本是装备在新A8上的第四代MMI系统)。其主要控制区位于挡把后方,更加靠近驾驶者,因此更加方便操作。

首先我们来看MMI系统的外部设计。在MMI系统出现之初有很多人表示很喜欢它的快捷键设计,这是相对于当时宝马的第一代iDrive系统而言的。不可否认,众多的快捷键可以为使用者提供更多的便利,但是其按键布局有些分散,甚至一个手掌都无法完全覆盖,这就意味着要想准确找到想按的那个键并不是那么容易。

MMI的系统操作方式也很简单,中间的那个旋钮承担了几乎全部的操作任务,左右旋转可以调节到不同的选项,按下中间的黑色部分就是确定操作。而中间的黑色钮还可以八方向拨动,这主要是为导航系统服务的。

MMI的导航系统除了可以为驾驶者指引路线外,还有一项特殊的功能,就是可以提供TMC实时交通流量信息。不同程度的拥堵情况都会以不同的颜色在地图上标注出来,但是并非所有道路都有相关信息,不过总强过没有。

Brake systems We all know that pushing down on the brake pedal slows a car to a stop. But how does this happen? How does your car transmit the force from your leg to its wheels? How does it multiply the force so that it is enough to stop something as big as a car? Brake Image Gallery Layout of typical brake system. See more brake images. When you depress your brake pedal, your car transmits the force from your foot to its brakes through a fluid. Since the actual brakes require a much greater force than you could apply with your leg, your car must also multiply the force of your foot. It does this in two ways: ?Mechanical advantage (leverage) ?Hydraulic force multiplication The brakes transmit the force to the tires using friction, and the tires transmit that force to the road using friction also. Before we begin our discussion on the components of the brake system, we'll cover these three principles: ?Leverage ?Hydraulics ?Friction Leverage and Hydraulics In the figure below, a force F is being applied to the left end of the lever. The left end of the lever is twice as long (2X) as the right end (X). Therefore, on the right end of the lever a force of 2F is available, but it acts through half of the distance (Y) that the left end moves (2Y). Changing the relative lengths of the left and right ends of the lever changes the multipliers.
