Abstract
A brake apparatus includes brake modules on the left and right wheels of the first and second axles and a controller that sets a target braking torque for each wheel based on a pedal sensor signal and controls each module accordingly, and, upon detecting a failure in one or more brake modules, identifies a yaw rate error between the target and current yaw rates using a motion sensor signal, distributes additional braking torque to the operational modules based on the yaw rate error, and adjusts their braking torque based on both the target and additional values.
Claims20
A brake apparatus comprising:
- a plurality of brake modules respectively provided in left and right wheels on a first axle of a vehicle;
- a plurality of brake modules respectively provided in left and right wheels on a second axle of the vehicle;
- and
- a controller configured to:
- set target braking torque for each wheel based on an output signal from a pedal sensor provided in the vehicle;
- and
- control braking torque of each of the plurality of brake modules based on the target braking torque for each wheel,
- wherein the controller is further configured to:
- identify an occurrence of a yaw rate error between a target yaw rate and a current yaw rate of the vehicle, based on an output signal of a motion sensor provided in the vehicle upon identifying a failure of at least one of the plurality of brake modules;
- distribute additional braking torque for each wheel to an operational brake module based on the yaw rate error;
- and
- control braking torque of the operational brake module based on the target braking torque for each wheel and the additional braking torque for each wheel.
A method of controlling a brake apparatus, which comprises a plurality of brake modules related to braking of left and right wheels on a first axle of a vehicle, a plurality of brake modules related to braking of left and right wheels on a second axle of the vehicle, and a controller, the method comprising:
- setting, by the controller, target braking torque for each wheel for the plurality of brake modules based on an output signal from a pedal sensor provided in the vehicle;
- identifying, by the controller, an occurrence of a yaw rate error between a target yaw rate and a current yaw rate of the vehicle based on an output signal from a motion sensor provided in the vehicle upon identifying a failure of at least one of the plurality of brake modules is identified;
- distributing, by the controller, additional braking torque for each wheel to the operational brake module based on the yaw rate error;
- and
- controlling, by the controller, braking torque of the operational brake module based on the target braking torque for each wheel and the additional braking torque for each wheel.
