Triple Hybrid Brake System (First Report)

－Proposed Brake System Architecture for Brake Weight Reduction and Ride Comfort Enhancement－

Abstract

As electrified vehicles become more widespread, the primary approach to braking is shifting from wheel brakes to regenerative brakes. Under these circumstances, this paper proposes a new brake system architecture called the triple hybrid brake system (THBS). THBS features a new high load brake installed on the vehicle body, and restricts the role of wheel brakes to low loads. As a result, THBS helps to reduce the unsprung mass. First, the basic design guidelines were obtained using a 2-DOF vibration model. Then the effect was confirmed by driving simulations of a 3-D vehicle dynamics model.
