Abstract
A braking system and method with redundant wheel speed sensing. In one example, the braking system includes a first electronic control unit connected to a first power supply and a second electronic control unit connected to a second power supply. The second electronic control unit is communicatively coupled to the first electronic control unit. The braking system also includes a first wheel speed sensor, a second wheel speed sensor, a third wheel speed sensor, and a fourth wheel speed sensor. The first wheel speed sensor and the second wheel speed sensor are directly coupled to and powered by the first electronic control unit and are communicatively coupled to the second electronic control unit. The third wheel speed sensor and the fourth wheel speed sensor are directly coupled to and powered by the second electronic control unit and are communicatively coupled to the first electronic control unit. The first electronic control unit and the second electronic control unit each configured to calculate a wheel speed from the first wheel speed sensor, the second wheel speed sensor, the third wheel speed sensor, and the fourth wheel speed sensor.
