摘要
为了弥补被动安全系统的不足,引进了磁力作用式主动安全概念,采用速度、距离传感器测定两车间的距离和速度差,然后分析制动距离特性;引入了危险估计系统,当结果为危险时,发送信息至前车,使两车电磁铁形成相同极性的磁场,从而产生"排斥力"阻止两车相撞。结合理论计算和模拟测试,结果表明这种方法在实际工程中具有实用价值。
To make up for the deficiency of the passive safety system,the magnetic force acting active safety concept is introduced.Through the speed sensor and distance sensor,the distance and speed between vehicles can be measured,then the braking length performance can be analyzed by the risky estimation system,if the result is risk,the vehicle behind transmitted information to the forward vehicle,then the two cars establish the same polarity of magnetic field to produce 'repulsion' to avoid the two cars crashed into each other.It is shown this method is practical in the project.
