The present disclosure relates to an electric brake system for an electric vehicle, which is more economical by simplifying a configuration of an electric vehicle that includes a main service brake and an electromagnetic brake, the electric brake system including an inductor, in a spherical shape, formed so that a drive axle penetrates through a center portion of the inductor; a plurality of springs inserted into holes defined in the inductor; an armature, in a disk shape, provided to contact the spring; and a friction disk mounted on a side of a motor, where a braking force is generated by operating the friction disk toward the armature.

A parking brake apparatus is provided for a vehicle having components of a parking brake system and devices for providing a plurality of output signals indicative of a plurality of vehicle factors. The parking brake apparatus comprises an electronic controller that monitors the output signals indicative of a plurality of vehicle factors, monitors for a pre-startup sequence of the plurality of vehicle factors having been met, monitors for a driver request to unpark the vehicle, monitors for a pre-release sequence of the plurality of vehicle factors having been met, and applies one or more control signals to components of the parking brake system to release parking brakes based upon a valid pre-startup sequence of the plurality of vehicle factors having been met, a driver request to unpark the vehicle, and at least one valid pre-release sequence of the plurality of vehicle factors having been met.

A parking brake apparatus is provided for a vehicle having components of a parking brake system and a number of devices providing a plurality of output signals indicative of a plurality of vehicle factors. The parking brake apparatus comprises an electronic controller arranged to (i) monitor the output signals indicative of a plurality of vehicle factors, and (ii) provide one or more control signals to be applied to components of the parking brake system to apply parking brakes based upon a predefined sequence of the plurality of vehicle factors having been met.

A brake actuator (1) for a vehicle includes a housing (5) and a piston (7) movably mounted inside the housing (5) and configured to reciprocate along a stroke axis (S) between a retracted position and an extended position for applying and releasing a braking force to and from a brake mechanism (101) of the vehicle. An electric motor (3) is operatively coupled to the piston (7) and configured to move the piston (7) rod between the retracted and extended positions such as to apply and release the braking force.

A differential travel sensor for a braking system of a vehicle includes: a field generation component, with the aid of which a first electrical and/or magnetic field having a predefined intensity distribution is generated in a spatial axis system fixedly definable with respect to a first body which is a driver brake force transmission component or an actuator force transmission component; and a sensor unit detecting at least one intensity variable of a second electrical and/or magnetic field generated due to an interaction of the first electrical and/or magnetic field with a second body, the second body being different from the first body and being the driver brake force transmission component or the actuator force transmission component.

An electric parking brake actuator has a transmission mechanism, which is rotationally drivable by an electric motor and converts rotational movement into an axial movement of an actuating rod that carries an actuating element for the parking brake. The actuating rod normally moves by electric motor displacement via the transmission mechanism from an unblocking position to a blocking position and vice versa. A blocking mechanism serves the purpose of holding the actuating rod in the unblocking position of the actuating rod against the force of a spring element. A blocking disc, which is in drive connection with the transmission mechanism, has a stop surface for a locking device in only one rotational direction of the blocking disc. For secondary alternate operation the stop surface is releasable by the locking device so that the actuating rod is biased by the spring element to the blocking position without electric-motorized assistance.

A work vehicle includes: a body; a travel device supporting the body; a travel driver configured to drive the travel device; a brake configured to lock and unlock the travel device; a deactivation operation tool manually movable to a first position, at which the brake is operable to be activated and deactivated, and a second position, at which the brake is kept deactivated; a position detector configured to detect that the deactivation operation tool is at the second position; and a notifier configured to provide, based on a result of the detection by the position detector, a notification that the deactivation operation tool is at the second position.

An electric motor-driven parking brake of a motor vehicle can be released in an emergency by applying emergency current from a parallel emergency current source to the motors controlling the parking brake. The direction of the emergency current is selected to reverse the motors, i.e., release the parking brake.

A self-driving work vehicle including a traveling apparatus, a vehicle body supported by the traveling apparatus on ground, a variable traveling power supply apparatus configured to supply rotational drive power to the traveling apparatus, a travel operation interface configured to adjust a rate of the rotational drive power, a parking brake provided for a transmission shaft of the variable traveling power supply apparatus, a rotation detector configured to detect rotation of the traveling apparatus or the transmission shaft, and a controller. The controller is configured or programmed to control the parking brake to a braking state or a non-braking state by a parking brake control module, and manage the braking state or the non-braking state as a vehicle body state by a condition management module. The braking state and the non-braking state are operating states of the parking brake.

A technique controls an electric brake of a vehicle. The technique involves continuously providing power to the electric brake of the vehicle to continuously disengage the electric brake and allow the vehicle to move. The technique further involves, while power is continuously provided to the electric brake and the vehicle is moving, sensing a fault condition. The technique further involves, in response to sensing the fault condition, providing electric pulses to the electric brake in place of continuously providing power to the electric brake, the electric pulses having varying pulse timing that controls braking of the vehicle. Accordingly, the vehicle is able to provide a more consistent braking response regardless of variations in certain factors such as brake calibration and/or current wear, the current weight in the vehicle, the current temperature, etc.
