A brake assembly may comprise a brake stack including a plurality of rotors and a plurality of stators. A piston assembly may be configured to apply a force to the brake stack. A brake control valve may be mounted to the piston assembly and fluidly coupled to a fluid inlet of the piston assembly.

To provide a parking brake apparatus for a saddled vehicle actuated in response to a reverse rotation on a throttle grip which is set in a simplified structure. A parking brake apparatus for a saddled vehicle includes a parking brake caliper configured to restrict a rotation of a rear wheel while the motorcycle is parked; a steering handle configured to steer a front wheel; and a throttle grip mounted on the steering handle and configured to control output of a power unit. The control unit actuates the parking brake caliper by a motor when at least the throttle grip is reversely rotated and the vehicle speed is zero. The throttle grip being reversely rotated is detected according to information from a throttle position sensor which is interlocked with the throttle grip.

A system includes a switch biased to a neutral position, a camera, and a computer communicatively coupled to the switch and the camera. The computer is programmed to activate a vehicle brake upon receiving data from the switch that the switch is in the neutral position and to activate the vehicle brake upon determining that an operator of the switch is in an inattentive state based on data received from the camera.

Provided are an apparatus and a method for parking control of a vehicle and the method includes a step in which a control unit determines a driver's parking intention by receiving a brake signal, pressure of a master cylinder, and a position of a shift lever from a brake switch, a pressure detection unit, and a shift lever detection unit, respectively; a step in which the control unit determines a state of the vehicle by receiving an inclination, a wheel speed, and a vehicle speed from an inclination detection unit, a wheel speed detection unit, and a vehicle speed detection unit, respectively; a step in which the control unit determines a state of an electronic parking brake; and a step in which the control unit operates the electronic parking brake through an EPB driving unit.

A driving support system installed on a vehicle includes a sensor detecting a vehicle state, a braking device, and a control device. The control device determines, based on the vehicle state, whether or not a first condition suggesting roll back of the vehicle is satisfied, and whether or not a second condition more strongly suggesting the roll back of the vehicle than the first condition is satisfied after the first condition is satisfied. When the second condition is satisfied after the first condition is satisfied, the control device executes roll back suppression control that controls the braking device to generate a braking force such that the vehicle stops. During a period from when the first condition is satisfied to when the second condition is satisfied, the control device executes precharge control that decreases play in the braking device without starting the roll back suppression control.

A vehicle braking system (20) has a primary braking unit (22) with a first pressure generating unit (34) and a first reservoir (26). The vehicle braking system (20) further has a secondary braking unit (24) with a second pressure generating unit (52) and second reservoir (70). A method of operating the vehicle braking system (20) includes actuating the pressure generating unit (34) of the primary braking unit (22) thereby pressurizing a fluid at a wheel cylinder (30) to slow or stop the vehicle. The wheel cylinder (30) is depressurized in response to an electrical signal provided to an electronic control unit (100,102). The fluid is transferred from the wheel cylinder (30) to the second reservoir (70). The fluid path (PI) between the wheel cylinder (30) and the second reservoir (70) is shorter and has less fluid resistance than the fluid path (P2) between the wheel cylinder (30) and the first reservoir (26). The present invention further comprises two braking systems. The present inventions are intended for fast pressure depressurization at quick start or launch control.

A control device for a vehicle including a first brake device that applies a braking force to vehicle wheels in response to a driver's operation of a brake, a second brake device that applies a braking force to the vehicle wheels through an electric actuator when a shifting operation position is switched to a parking position, and a parking lock mechanism that stops rotation of the vehicle wheels by stopping rotation of a parking gear interlocking with the vehicle wheels when the shifting operation position is switched to the parking position. The control device includes an electronic control unit configured to maintain an operating state of the first brake device until the braking force is applied to the vehicle wheels by the second brake device when the shifting operation position is switched to the parking position after the first brake device has been operated by the driver.

Driving support ECU transmits a communication connection request to a help net center HNC when a driver of a vehicle has been determined to be in an abnormal state where the driver loses an ability to drive the vehicle, and when the communication connection to the help net center HNC has been established, the driving support ECU transmits the help signal (the positional information of the vehicle) and decelerates the vehicle at a constant deceleration to make the vehicle stop. On the other hand, when the communication connection to the help net center HNC has not been established, the driving support ECU makes the vehicle travel at a constant speed. Accordingly, it is possible to make the vehicle stop under a situation where the help net center HNC recognizes the vehicle position inside which the driver who has been determined to be in the abnormal state is.

A rail train brake control system, comprising: a single vehicle brake control unit, a train brake control unit, a traction control unit and a communication control unit; the single vehicle brake control unit is provided in each vehicle of the rail train, the train brake control unit and the communication control unit are provided in the vehicles at both ends of the rail train, and the traction control unit is disposed in motor vehicles of a plurality of vehicles; and the single vehicle brake control unit, the train brake control unit, the traction control unit and the communication control unit implement communication by means of the gateway. The system can realize flexible marshalling of a train. Further disclosed is a train comprising the train brake control system.

A host vehicle includes a driver re-engagement assessment system and an X-by-wire device adapted for both manual control and automated control by an automated guidance system. The driver re-engagement assessment system includes a controller, a user interface, and test execution module and a test evaluation module. The user interface is configured to interface with an occupant and output an occupant directive signal for manual control to the controller. The test execution module initiates an occupant re-engagement test upon receipt of the occupant directive signal by the controller. The test evaluation module is configured to receive an occupant performance signal indicative of occupant performance during the re-engagement test, and evaluate the occupant performance signal to determine a test pass result and a test fail result. The manual control of the host vehicle is assumed by the occupant upon the determination of the test pass result.
