ESP汽车电子稳定系统论文.doc

汽车电子稳定系统(Electronic Stability Program ,简称 ESP) 。 ESP 是一种汽车新型主动安全系统。 ESP 系统包含 ABS (防抱死刹车系统)及 ASR (防侧滑系统),是这两种系统功能上的延伸。因此, ESP 称得上是当前汽车防滑装置的最高级形式。 ESP 系统实际是一种牵引力控制系统,与其他牵引力控制系统比较, ESP 不但控制驱动轮,而且可控制从动轮。如后轮驱动汽车常出现的转向过多情况,此时后轮失控而甩尾, ESP 便会刹慢外侧的前轮来稳定车子;在转向过少时,为了校正循迹方向, ESP 则会刹慢内后轮,从而校正行驶方向。有 ESP 与只有 ABS 及 ASR 的汽车, 它们之间的差别在于 ABS 及 ASR 只能被动地作出反应,而 ESP 则能够探测和分析车况并纠正驾驶的错误, 防患于未然。 ESP 对过度转向或不足转向特别敏感, 例如汽车在路滑时左拐过度转向(转弯太急)时会产生向右侧甩尾,传感器感觉到滑动就会迅速制动右前轮使其恢复附着力,产生一种相反的转矩而使汽车保持在原来的车道上。当然,任何事物都有一个度的范围,如果驾车者盲目开快车,现在的任何安全装置都难以保全。关键词: ESP 主动安全系统汽车防滑装置电子控制 Abstract Electronic stability system (Electronic Stability Program, ESP). ESP isa new type of automotive active safety systems. The ESP system with ABS (antilock brake system) and ASR (anti-skid system), is the extension of these two systems function. Therefore, the ESP regarded as the most advanced form of automotive anti-skid device. The ESP system is actually a traction control system and other traction control systems, ESP not only control the driving wheel driven wheel, and can be controlled. Such as the rear-wheel drive vehicles often turn to excessive rear wheel out of control while the drift, the ESP will brake slow the outside front wheel to stabilize the car; turning over came from order to correct the tracking direction, ESP will slowly brake the inside rear wheel, in order to correct the direction of travel. Car with ESP and ABS and ASR, the difference between them lies in the ABS and ASR can only passively react, ESP is able to detect and analyze the condition and correct driving errors and take preventive measures. ESP on oversteer or understeer are particularly sensitive, such as cars turn left in slippery when oversteer (a turn too fast) will have to drift to the right side of the sensor felt the right front wheel slide will brake quickly to restore adhesion produce an opposing torque leaving the car remained in the original lane. Of course, everything has a range of motorists speeding blindly any safety devices are diffi
