An actuator for a wheel brake unit of a vehicle is disclosed, wherein the actuator has an actuation element for performing an actuation, and is configured to receive, through a power supply, a power for performing the actuation. The actuator is characterized by a detection unit, configured to receive a control signal and to detect a power shortage indicative of an emergency situation, and to generate an emergency signal if the control signal is received or if the power shortage is detected, as well as by a backup energy storage, configured to store energy sufficient for causing the actuation element to perform a complete brake actuation at least once and, upon receiving the emergency signal, to provide at least a part of the energy needed by the actuation element to perform the actuation.

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.

This power supply device is provided with: a primary power supply system for supplying power to a motor for rotary-driving a running wheel; a voltage converter unit for converting voltage by being supplied with a part of the power from the primary power supply system; a secondary power supply system for supplying electric power converted by the voltage converter unit to a steering device; and a primary backup power supply for supplying power to the voltage converter unit. The primary backup power supply makes it possible to supply the power to the voltage converter unit when the voltage of the power detected by a VD of the primary power supply system becomes smaller than a predetermined value.

The present disclosure includes a system, method, and device related to controlling brakes of a towed vehicle. A brake controller system includes a brake controller that controls the brakes of a towed vehicle based on acceleration. The brake controller is in communication with a speed sensor. The speed sensor determines the speed of a towing vehicle or a towed vehicle. The brake controller automatically sets a gain or boost based on the speed and acceleration.

The present invention discloses an electric parking brake control device capable of accurately determining operation of an electric actuator. The electric parking brake control device is capable of performing an application process for controlling the electric actuator to move in the direction in which a friction member is pressed against a rotation body that rotates integrally with a wheel and a release process for controlling the electric actuator to move in the direction in which the friction member is moved away from the rotation body. Even upon receiving (time t12) a new operation request for operating the electric actuator during a period (time t1 to t5) from the start of the application process or the release process to the completion of the process, the electric parking brake control device does not change the operation of the electric actuator on the basis of the operation request.

Aspects of the present disclosure relate generally to limiting the use of an autonomous or semi-autonomous vehicle by particular occupants based on permission data. More specifically, permission data may include destinations, routes, and/or other information that is predefined or set by a third party. The vehicle may then access the permission data in order to transport the particular occupant to the predefined destination, for example, without deviation from the predefined route. The vehicle may drop the particular occupant off at the destination and may wait until the passenger is ready to move to another predefined destination. The permission data may be used to limit the ability of the particular occupant to change the route of the vehicle completely or by some maximum deviation value. For example, the vehicle may be able to deviate from the route up to a particular distance from or along the route.

A work vehicle provided with a loading hydraulic circuit (A), including at least a main hydraulic pump (31), a lift arm cylinder (8) and a control valve (32), an auxiliary hydraulic pump (31), a negative parking brake device (PB), and a parking brake releasing hydraulic circuit (B2), in which the vehicle includes: a loading operation hydraulic circuit (B1) located upstream of the parking brake releasing hydraulic circuit; an emergency flow path (80) for supplying the pressure oil discharged from the auxiliary hydraulic pump to the parking brake device through the loading operation hydraulic circuit in an emergency; and a valve unit (81) located in the emergency flow path. If the pressure of the parking brake releasing hydraulic circuit is lower than the brake release pressure to release the braking state of the parking brake device, the valve unit is switched to the communicating position.

A remote support system provides support to an autonomous drive system of a vehicle in response to a support request. The remote support may include guiding the autonomous drive system of the vehicle through a hazardous environment. A call to the remote support system may be initiated, for example, via a user interface control button or by scanning a bar code, QR code, or RFID associated with the vehicle on a device that sends the code with vehicle information to the remote support system. The remote support system may determine an urgency of the request to assess whether immediate support should be initiated or whether to first initiate a communication connection with a passenger. Furthermore, an emergency brake system of the vehicle may be triggered by the remote support system or in response to the vehicle losing a connection to the remote support system during a support request.
