A travel sensing system for real-time verification and safety redundancy comprises a double-magnet triggering mechanism connected with a brake pedal through a linkage mechanism and a double-independent magnetic induction channel sensing unit arranged outside the double-magnet triggering mechanism. Wherein the linkage mechanism drives the double-magnet triggering mechanism and the double-independent magnetic induction channel sensing unit to generate relative displacement according to the rotation of the brake pedal; the double-independent magnetic induction channel sensing unit achieves real-time verification of the position of a brake pedal and stroke sensing of safety redundancy by detecting changes of two superimposed magnetic fields of the double-magnet triggering mechanism. The industrial pain points of unexpected failure and low reliability of the stroke pedal signal of the electro-hydraulic drive-by-wire brake are solved, and the safety and the reliability of the drive-by-wire brake system are improved.
一种实时校验和安全冗余的行程感知系统,包括:与刹车踏板通过连动机构相连的双磁铁触发机构以及设置于双磁铁触发机构外部的双独立磁感通道传感单元,其中:连动机构根据刹车踏板的转动进而驱动双磁铁触发机构与双独立磁感通道传感单元发生相对位移,双独立磁感通道传感单元通过检测双磁铁触发机构的两个叠加磁场的变化实现对刹车踏板位置的实时校验和安全冗余的行程感知。本发明解决电液线控制动器行程踏板信号非预期失效、可靠性低的行业痛点,提高了线控制动系统的安全性和可靠性。
