A aircraft braking system is disclosed including a plurality of brakes each for braking one of a plurality of aircraft wheels using hydraulic pressure, a first hydraulic pressure supply unit, and a second hydraulic pressure supply unit. The first hydraulic pressure supply unit is connected to only a first subset of the plurality of brakes, such that the first hydraulic pressure supply unit can enable only the first subset of the plurality of brakes to provide braking. The second hydraulic pressure supply unit is connected to only a second subset of the plurality of brakes, the second subset not including any of the brakes of the first subset, such that the second hydraulic pressure supply unit can enable only the second subset of the plurality of brakes to provide braking.

Driving support ECU sets a driver's state to temporarily abnormal and decelerates a vehicle when a driver of the vehicle has been first determined to be in an abnormal state where the driver loses an ability to drive the vehicle. Driving support ECU changes the driver's state to regularly abnormal in a case when the abnormal state of the driver remains unchanged when a vehicle speed decreases to a set vehicle speed, and at this point, reports to a help net center HNC. With this configuration, a report to the help net center HNC can be made at an appropriate timing.

A remote stop system for a vehicle configured to be operated autonomously or semi-autonomously. The remote stop system includes a remote stop controller configured to be installed on the vehicle and a remote stop actuator configured to send a wireless control signal to the remote stop controller. The remote stop actuator has a first state having the remote stop actuator continuously transmitting the wireless control signal to the remote stop controller; and a second state having the remote stop actuator without transmitting the wireless control signal to the remote stop controller. In the second state, an engine of the vehicle is automatically stopped simultaneously with applying a braking force to the vehicle. A vehicle system includes the vehicle and the remote stop system.

A method for the assisted emergency braking of a vehicle, in which the lateral and/or the longitudinal guidance of the vehicle are/is influenced in such a way that the vehicle is guided in the direction of a safety zone, and when the safety zone has been reached, a parking position, in particular within the safety zone, is ascertained for the vehicle, the vehicle being guided in such a way that the vehicle comes to a standstill in the parking position.

A hydraulic arrangement is disclosed for distributing a fluid in pressure coming from a source of fluid in pressure among hydraulic units of a work vehicle. The hydraulic arrangement includes a priority valve configured to divide the flow of the fluid source between a subset of the hydraulic units on the base of an equivalent load sensing signal derived from the hydraulic units. The hydraulic arrangement further includes by-pass means fluidly interposed between the source and the subset of the hydraulic units and configured to allow direct passage of fluid by-passing priority valve from the source to the subset of the hydraulic units according to a predefined condition.

A method includes ascertaining that an emergency braking operation of a single-track motor vehicle is to be automatically executed driver independently, and based on the ascertainment, automatically and driver-independently influencing a steering element of the motor vehicle during the execution of the emergency braking operation.

An improved system for braking an agricultural vehicle propelled by a hydrostatic drive unit is disclosed. An operator provides a desired speed command from a first user interface, such as a joystick. The joystick generates a command responsive to the deflection and communicates the command to a controller. The agricultural vehicle also includes a second user interface, such as a brake pedal. The brake pedal includes a transducer configured to generate a signal corresponding to a deflection of the brake pedal which is also communicated to the controller. If the operator presses the brake pedal when the joystick is commanding motion, the controller reduces the signal from the joystick. The amount the signal is reduced increases as the deflection of the brake pedal increases until the brake pedal overrides any speed command from the joystick.

A compressed air supply device for a rail vehicle, having a main compressor for generating compressed air for a pneumatic brake system and a vehicle battery for supplying electric energy. The compressed air generator for supplying additional auxiliary air for operating at least one pneumatic actuator is provided in a frame of an adjusting drive for a pantograph. The compressed air generator for supplying auxiliary air includes an electric frequency converter for operating the electric-motor driven main compressor of the rail vehicle with low rotational speed from the electric drive energy provided by the vehicle battery. A secondary line is attached to the compressed air line connected to the main compressor to branch off the auxiliary air for the supply of auxiliary air of the actuator.

A brake booster system for assisting a braking operation of a motor vehicle having a brake booster is provided. The brake booster system may include a pressure piston of a brake master cylinder, an actuating element which is configured for deflecting the pressure piston, and a brake booster which is divided into two chambers by way of a diaphragm, the first chamber is connected to the pressure piston and has a pressure p1 and the second chamber is connected to the actuating element and has a pressure p2. Furthermore, in the brake booster system, there is a pressure build up apparatus which is configured to raise the pressure p2 above the pressure p1 by way of said pressure build up apparatus.

The present invention obtains a controller and a control method capable of improving operability of a motorcycle.

In a controller 30 and the control method according to the present invention, an execution section of the controller 30 executes holding control for braking and holding a motorcycle 1 without relying on a brake operation by a rider of the motorcycle 1 at a stop of the motorcycle 1. The execution section switches a cancellation condition of the holding control between a first condition, under which the holding control is canceled on the basis of an output increase index value of a drive source (an engine 11) and connection state information of a clutch 12, and a second condition, under which the holding control is canceled not on the basis of the output increase index value but on the basis of the connection state information, according to a gradient of a road surface.
