不過文章引用完整一些,會比較容易說明
Electronic Stability Control (ESC) is a safety system designed to recognize adverse
driving conditions by 1) continuously measuring and evaluating the speed, the steering
wheel angle, the yaw rate, and the lateral acceleration of a vehicle from various sensors
and 2) using those measured data to compare a driver’s steering input with the vehicle’s
actual motion. If an unstable situation is detected, then ESC automatically intervenes to
assist the driver and stabilize the vehicle by applying the brakes to individual wheels as
needed and possibly reducing engine torque. This technology is expected to reduce the
number of crashes due to driver error and loss of control, because it has the potential to
anticipate situations leading up to some crashes before they occur and the capability to
automatically intervene to prevent them. A major benefit should be the reduction of
single-vehicle crashes that involve losing control and running off the road.
...省略...
The types of crash involvements where ESC would likely or at least possibly have an
effect are: vii
• Single-vehicle crashes in which a vehicle ran off the road and then hit a fixed
object and/or rolled over.
• Involvements as a culpable party in a multi-vehicle crash on a dry or wet road.
• Collisions with pedestrians, bicycles, or animals.
於Vii頁指出ESC系統對於幾種車輛事故的預防效果,其中也包含翻滾
ESC/ESP最主要還是藉由輪胎的循跡性來了解車身穩定否
介入控制的手段甚至包含引擎的輸出,延緩方向機的動作,以避免駕駛人做出影響車身穩定的動作
但是如果是直接撞擊,而無任何可供系統參考的預警條件,那麼ESC/ESP也是無用武之地
這需要其他的預警系統來介入,像是疲勞駕駛,ACC之類的
但是因此開車是不能因為有這些系統便太過放心
幸好車主是沒有大礙,也未引起他人傷亡
