Constructor & Destructor Documentation

chrono::vehicle::ChBrake::ChBrake ( const std::string &  name)
[in]namename of the subsystem

Member Function Documentation

virtual void chrono::vehicle::ChBrake::Synchronize ( double  modulation)
pure virtual

Update the brake subsystem: set the brake modulation.

The input value is in the range [0,1].
modulation = 0 indicates no braking
modulation = 1 indicates that the subsystem should provide maximum braking torque

Implemented in chrono::vehicle::ChBrakeSimple.
