  • Patent number: 9827961
    Abstract: A method is provided for detecting a fault condition in a hydraulic brake system of a vehicle having a first hydraulic brake circuit and a second hydraulic brake circuit. A correlation ratio is determined between a measured pressure and the actual vehicle acceleration. A first wheel velocity differential is determined and a second wheel velocity differential is determined. A weighting value is selected in response to determining whether the correlation ratio is within the predetermined range and whether the first wheel velocity differential and the second wheel velocity differential are opposite signs. The selected weighting value is added to a fault counter. A determination is made whether the fault counter is equal to or greater than a predetermined threshold. A fault condition is detected in response to the fault counter greater than or equal to the first predetermined threshold.

  • Publication number: 20170217418
    Abstract: A brake system includes first and second wheel brakes, a reservoir, and a brake pedal unit having a housing and a pair of output pistons slidably disposed in the housing. The output pistons generate brake actuating pressure during a manual push-through mode for actuating the first and second wheel brakes. The system further includes a plunger assembly having a housing having first and second ports, a motor driving an actuator, and a piston connected to the actuator. The piston pressurizes a first chamber when the piston is moving in a first direction to provide fluid flow out of the first port. The piston pressurizes a second chamber when the piston is moving in a second direction opposite the first direction to provide fluid flow out of the second port. The first and second ports are selectively in fluid communication with the wheel brakes.

  • Patent number: 9707967
    Abstract: A method of traction control for a vehicle. Lateral and longitudinal accelerations are measured for a vehicle. A maximum supportable drive torque for a first wheel of the vehicle is calculated as a function of the lateral and longitudinal accelerations. A commanded vectoring brake torque is applied to the first wheel using a brake device. The commanded vectoring brake torque is an amount by which a driveline torque delivered to the first wheel exceeds the maximum supportable drive torque.
