US 11,590,943 B2 · Control system of brake-by-wire device

Abstract

A control system of a BBW device may include brake-by-wire (BBW) devices provided to each of wheels of a vehicle to perform a braking control or a suspension control of the vehicle, sensors configured for detecting an operating state of each of the BBW devices, and controllers connected to each of the BBW devices to control a corresponding BBW device among the BBW devices, in which the controllers are configured to determine whether the sensors fail according to data received from the sensors, and when determining that any a sensor among the sensors fails, the controllers turn off any a BBW device of the BBW devices which is a target detected by the failed sensor, and perform the braking control or the suspension control of the BBW devices based on a traveling state of the vehicle.

Dependent claims

A control system of brake-by-wire (BBW) devices, the control system comprising:

the BBW devices provided to each of wheels of a vehicle to perform a braking control or a suspension control of the vehicle;
sensors configured for detecting an operating state of each of the BBW devices;
and
controllers connected to each of the BBW devices to control a corresponding BBW device among the BBW devices,
wherein each of the BBW devices include a motor configured for providing a driving force to perform the braking control or the suspension control of the vehicle,
wherein the controllers are configured to determine whether the sensors fail according to data received from the sensors, and
wherein upon determining that a sensor among the sensors fails, the controllers turn off a BBW device of the BBW devices which is a target detected by the failed sensor, and perform the braking control or the suspension control of the BBW devices according to a traveling state of the vehicle.
