Abstract
A brake control unit includes a processor, a first high side driver and a second high side driver. The processor sends signals to the first high side driver and the second high side driver. The first and second high side drivers process the signals independent of each other. The processor diagnoses faults and locations of faults based on feedback from the high side drivers. The first high side driver controls the braking of a first trailer brake. The second high side driver controls the braking of a second trailer brake.
Claims17
A brake control unit comprising:
- a processor;
- a first high side driver;
- and
- a second high side driver, wherein the processor is coupled to the first high side driver through a first connection and the second high side driver through a second connection, and
- wherein the processor generates a first signal to be applied to the first connection in order to induce braking in at least one first brake of a towed vehicle, and generates a second signal to be applied to the second connection in order to induce braking in at least one second brake of the towed vehicle.
A brake control unit comprising:
- a processor;
- a diagnostic circuit comprising:
- a first driver;
- and
- a second driver comprising a plurality of field effect transistors, wherein the processor is coupled to the first driver and the second driver and wherein the first driver is connected with the second driver.
A brake control unit comprising:
- a processor;
- a first driver;
- and
- a second driver, wherein the processor is coupled to the first driver and the second driver and wherein a power device is connected to the second driver in series.
A brake control unit comprising:
- a processor;
- a power device, and
- a driver electrically connected to the power device in series.
