Abstract
A braking management system for a vehicle having a driveline that has a transmission featuring a continuously variable planetary variator, the braking management system comprising a processor adapted to actuate one or more braking mechanisms based on current state of the vehicle and a braking input from a vehicle operator. The system may prioritize some mechanisms over others to optimize vehicle efficiency or vehicle component longevity.
Claims9
A braking management system for a vehicle driveline having a transmission incorporating a CVP, the system comprising:
- a processor (sub-control unit) operably connected to the vehicle driveline and adapted to actuate one or more of the following braking mechanisms:
- (a) an engine selectively coupleable to the vehicle driveline and configured exert a braking torque on the driveline;
- (b) a CVP drivingly engaged with the engine and configure to rev-up the engine by altering its speed ratio and routing power from the vehicle driveline to the engine, thereby transferring the vehicle's kinetic energy into the kinetic energy of the engine, and thus braking the vehicle;
- (c) frictional losses in the CVP;
- (d) clutches in the transmission of the vehicle driveline;
- (e) service brakes coupled to the vehicle driveline;
- (f) one or more centrifugal brakes coupled to the vehicle driveline;
- or
- (g) one or more additional brakes coupled to the vehicle driveline
