Abstract
Systems and methods control operation of multiple compressors of a multi-compressor assembly on a vehicle. A controller determines a leak rate of a brake system of a vehicle. The controller changes a pressure threshold at which one or more compressors are activated to supply gas to the brake system based on the leak rate. The controller activates at least a first compressor of the one or more compressors to increase a gas pressure of the brake system based on the gas pressure of the brake system falling below the pressure threshold that is changed.
Claims20
A system comprising:
- a controller configured to determine a leak rate of a brake system of a vehicle, the controller also configured to change a pressure threshold at which one or more compressors are activated to supply gas to the brake system based on the leak rate, the controller configured to activate at least a first compressor of the one or more compressors to increase a gas pressure of the brake system based on the gas pressure of the brake system and the pressure threshold that is changed.
A system comprising:
- a controller configured to:
- determine a leak rate of a brake system of a vehicle;
- change a first pressure threshold to a second pressure threshold at which one or more compressors are activated to supply gas to the brake system based on the leak rate;
- determine whether pressure of the brake system is less than the second pressure threshold;
- and
- based on the pressure in the brake system and the second pressure threshold, activate at least a first compressor of the one or more compressors to increase the pressure of the brake system.
A system comprising:
- a brake system;
- a compressor assembly comprising a first compressor;
- a sensor to monitor pressure in the brake system;
- and
- a controller configured to:
- determine a leak rate of the brake system of a vehicle;
- change a first pressure threshold to a second pressure threshold at which one or more compressors are activated to supply gas to the brake system based on the leak rate;
- determine whether pressure in the brake system is less than the second pressure threshold;
- and
- based on the pressure in the brake system and the second pressure threshold, activate at least the first compressor of the one or more compressors to increase a gas pressure of the brake system.
