MULTI-SENSOR FUSION BASED SELF-DETECTION SYSTEM AND METHOD FOR DISC BRAKES

摘要

A multi-sensor fusion based self-detection system and method for disc brakes. When a vehicle is in a braking condition, a braking force calculation unit (24) collects vehicle yaw velocity w₁, vehicle longitudinal acceleration a₁ and vehicle lateral acceleration a₂ that are measured by a single-antenna GPS module (23), and calculates the actual braking force of brakes (5, 13, 17, 21); a contact force calculation unit (26) calculates the contact force between brake pads (81, 82, 83, 84) and brake discs (9, 12, 16, 19); and a braking efficiency factor self-measurement unit (25) collects actual braking force signals and contact force signals, calculates braking efficiency factors, and determines whether the brakes (5, 13, 17, 21) are located in a safe working area.
