Combi Brake System (CBS) Design and Tuning on an Electric Two Wheeler for Cornering Maneuver 2019-28-2399

To reduce the number of traffic accidents, most of the governments have mandated to include Combi Brake System (CBS) or Anti-lock Braking System (ABS) in two wheelers. While most of the homologation requirements for CBS can be fulfilled by straight line motion, CBS behavior is crucial while cornering for safety aspects. When vehicle is in cornering motion, the lateral forces generated at the tire decreases the effective longitudinal force available, which implies lesser braking force at tire.
This paper represents a design methodology for tuning CBS for various critical scenarios mainly during cornering maneuver. A detailed study has been made at various combination of vehicle lean angle, vehicle speed and friction coefficient of road (μ) in straight line and cornering maneuver to effectively decide on front to rear brake force distribution to avoid either of the tires’ lock-up. A co-simulation is done with BikeSim and Simulink softwares, where vehicle model is developed in BikeSim and CBS control algorithm in Simulink. Both the models are correlated against real test data.
