Independent Redundant Wheel Speed Processing System and Method

Abstract

An independent redundant wheel speed processing system is provided. The system includes four wheel speed sensors respectively disposed on four wheels and four wheel speed signal processing units. The four wheel speed sensors are respectively in communication with an MCU through the four wheel speed signal processing units. Each of the four wheel speed signal processing units diagnoses drive abnormalities and wheel speed signal abnormalities of one of the four wheel speed sensors, and sends diagnostic results to the MCU. The present disclosure ensures the functional safety and redundancy requirements of the braking system by providing independent and discrete wheel speed signal processing units, while also reducing the high costs incurred by using highly integrated chips to fulfill these requirements.

Dependencies are inferred from the claim text.
