A locking knob for an air brake valve may include a push rod and a locking ring. The push rod may include a knob head at a first end of the push rod, first thread along an exterior surface of the push rod, and a cavity within the push rod exposed at a second end of the push rod opposite of the first end, the cavity configured to house an actuating arm of the valve that is held fixed to the push rod. The locking ring may include a channel that is configured to house the push rod, and second thread within the channel that is configured to mate with the first thread. Rotation of the locking ring restricts movement of the push rod and actuating arm.

An aspect of the present disclosure relates to a vehicle control system configured to control a vehicle. The vehicle control system includes an electronic control unit configured to limit a driving force to be applied to the vehicle based on a brake temperature that is a temperature of a friction brake provided on a wheel of the vehicle.

A parking brake control device controls a hydraulic pressure unit for braking wheels hydraulically and a parking brake device for braking the wheels by transmitting power of an electric motor to the wheels mechanically. The parking brake control device includes a hydraulic brake control unit capable of exercising a hydraulic brake control under which a brake is applied to the wheels by the hydraulic pressure unit, on condition that a signal is received from an actuation switch for actuating the parking brake device, while a vehicle is running, and a pressure decrease rate setting unit configured to set a pressure decrease rate according to a closing condition satisfied upon entry into the closing stage of the hydraulic brake control when a pressure decrease control is exercised in a closing stage of the hydraulic brake control.

A braking control device includes a fluid pump driven by an electric motor via a coupling part, a differential pressure valve provided in a fluid path connecting a discharge part and an intake part of the fluid pump, the differential pressure valve increasing a wheel pressure of a wheel cylinder by increasing a braking liquid discharged from the fluid pump to an output pressure, and a controller that drives the electric motor and the differential pressure valve. When a valve opening amount of the differential pressure valve is reduced in a state in which the electric motor is driven, the controller performs an appropriateness determination as to whether or not the coupling part is normal based on a change in a state quantity related to the electric motor.

A fail-open mechanism employed in a disk brake that is an electric brake apparatus includes a spring clutch disposed between a spindle and a torque transmission member and configured to cause the torque transmission member to rotate together with the spindle until a rotational resistance force between the spindle and the spring clutch exceeds a predetermined value, a non-rotatably configured fixation member, and a torsion spring having a one-end portion connected to the torque transmission member and an opposite-end portion connected to the fixation member and configured to store elastic energy therein due to a rotation of the torque transmission member relative to the fixation member according to the rotation of the spindle. As a result, the disk brake can prevent or reduce the impairment of layout flexibility thereof.

A brake pedal device includes: a housing fixed to a vehicle; a brake pedal provided to be swingable about a predetermined axis with respect to the housing and to receive a depression operation of a driver; and at least three sensors that output signals according to an operation amount of the brake pedal. The at least three sensors include at least one magnetic sensor and at least two inductive sensors, for example. The at least two inductive sensors are spaced apart from each other such that a movement of a target metal of one inductive sensor is detected by a sensing coil of the one inductive sensor but a movement of a target metal of any other inductive sensors is not detected by the sensing coil of the one inductive sensor.

A method for controlling an actuatable safety device for protecting an occupant of a vehicle includes utilizing an advanced driver assistance system (ADAS) to determine that a vehicle collision is impending. In response to determining the existence of an impending vehicle collision, a mass spring damper model uses sensed vehicle longitudinal acceleration (IMU_X) to estimate the occupant movement that will result from the impending vehicle collision. The estimated occupant movement is used to determine how to control deployment of an actuatable safety device in response to the crash.
