Abstract
A brake system includes a piston for applying an output force to a brake, a motor operatively connected to the piston and a controller receiving a braking request and sending a brake force signal commanding a level of brake force to the motor to cause the motor to move the piston and apply an output force to the brake. When the brake force signal remains at a first level for a given period of time, the controller automatically decreases, or increases and then decreases, the level of the brake force signal from a first value. Also a method of controlling such a brake system.
Claims19
In a brake system comprising a piston for applying an output force to a brake based on a commanded brake force, a method comprising the steps of:
- monitoring the commanded brake force;
- and
- after the commanded brake force has remained at a substantially constant level for a given period of time, automatically decreasing the commanded brake force.
In a brake system comprising:
- a piston for applying an output force to a brake;
- a motor operatively connected to the piston;
- and
- a controller receiving a braking request and sending a brake force signal commanding a level of brake force to the motor to cause the motor to move the piston and apply an output force to the brake;
- a method comprising the steps of:
- when the brake force signal remains at a first level for a given period of time, automatically increasing the level of the brake force signal from a first value;
- and
- thereafter automatically decreasing the level of the brake force signal.
A brake control system comprising:
- a piston for applying an output force to a brake;
- a motor operatively connected to the piston;
- and
- a controller sending a brake force signal the motor to cause the motor to move the piston, the controller, when the brake force signal remains at a first level for a given period of time, automatically increasing the brake force signal, and thereafter automatically decreasing the brake force signal.
