The invention discloses an electronic steering column lock bolt position measuring system, which is characterized in that a force sensor and a displacement sensor are fixed at the upper end of an ejector rod of a moving electric cylinder, and the upper end of the displacement sensor is higher than the upper end of the force sensor; during measurement, the force sensor is located under the spring bolt. The upper end of a displacement telescopic rod of the displacement sensor is located under the electronic steering column lock and located outside the vertical projection area of the spring bolt. The force sensor is used for detecting the pressure at the upper end and sending a pressure signal to the processor; when the upper end of the displacement telescopic rod is compressed, the displacement sensor outputs a pulse signal to the processor in a short time; a displacement telescopic rod of the displacement sensor outputs a pulse signal every time the displacement telescopic rod is shortened by a set distance; the processor controls the motion electric cylinder to work and determines the unlocking position or the locking position of the electronic steering column lock bolt according to the number of pulses output by the displacement sensor when the pressure detected by the force sensor changes suddenly. The electronic steering column lock bolt position measuring system can detect and obtain accurate locking and unlocking positions of the ESCL bolt.
本发明公开了一种电子转向柱锁锁舌位置测量系统,力传感器及位移传感器均固定在运动电缸的顶杆上端,并且位移传感器上端较力传感器上端高;测量时,力传感器位于锁舌正下方;位移传感器的位移伸缩杆上端位于电子转向柱锁正下方并位于锁舌竖向投影区外;力传感器用于检测其上端的压力并将压力信号发送到处理器;位移传感器当其位移伸缩杆上端受压缩短时输出脉冲信号到处理器;位移传感器的位移伸缩杆每缩短设定距离输出一个脉冲信号;处理器控制运动电缸工作,并根据力传感器检测的压力突变时的位移传感器输出的脉冲个数,确定电子转向柱锁锁舌的解锁位置或上锁位置。该电子转向柱锁锁舌位置测量系统,能检测得到精确的ESCL锁舌的上锁、解锁位置。
