Abstract
A vehicle braking system including a controller, in an initial anti-skid cycle, performs a first determination to select a high or a low control mode in accordance with wheel speed parameters. The controller in a second, or subsequent anti-skid cycle, performs a second determination to determine whether a near μ test is to be performed in accordance with wheel speed parameters. The controller consequent upon selection of low control mode performs a near μ test. The near μ test includes performing a rise in the brake pressure and then selecting a high or low mode in accordance with the speed of the wheels resulting from the rise in brake pressure in the near μ test.
Claims24
A vehicle braking system comprising:
- means, in an initial anti-skid cycle, to perform a first determination to select a high mode or a low control mode in accordance with wheel speed parameters;
- means in a second, or subsequent anti-skid cycle, to perform a second determination to determine whether a near μ test is to be performed in accordance with the wheel speed parameters;
- means, consequent upon selection of low mode to perform the near μ test, the near μ test comprising performing a rise in the brake pressure and then selecting a high mode or low mode in accordance with the speed of the wheels resulting from said rise in brake pressure in the near μ test.
