Solver Variables
Solver Variable | Comments |
---|---|
Front brake line pressure | Computes pressure in front brake line. PFront = KBrake boost * FFront/AreaMC_front |
Rear brake line pressure | Computes pressure in front brake line. PRear = KBrake boost * FRear/AreaMC_rear |
Brake bias (forwards) | User defined solver variable. FFront = BB * FMC |
Brake boost ratio | User defined solver variable. PBrake line = KBrake boost * PMC Default brake boost ratio is a user defined constant in the Brake system info dataset. |
Driver brake demand | User defined solver variable. If used in an analysis (a driving analysis for example), analysis is expected to override this solver variable. |
