A brake system includes a service brake and a parking brake that brake a vehicle including a lift axle capable of ascending and descending. The brake system further includes a brake blocker device and a controller that controls the brake blocker device. The brake blocker device blocks at least one of supply of compressed air to the service brake and supply of compressed air to the parking brake. The service brake and the parking brake act on the lift axle. The controller actuates the brake blocker device when the lift axle is at a lifted position.

Brake system and brake control method

An air dryer includes a supporting base, a drying agent container, and an outer cover. The supporting base includes an inlet for receiving compressed air to be subject to a drying process and an outlet for delivering the processed compressed air that has undergone the drying process. The drying agent container is a container supported on the supporting base, contains a drying agent in the interior, and enables the drying process to be performed by passing the compressed air from the inlet through the drying agent. The outer cover surrounds the outer side of the drying agent container on the supporting base and defines a chamber for storing the compressed air between itself and the drying agent container. The supporting base includes first and second mounting surfaces, which are oriented in different directions, and a plurality of inlets, which are oriented in different directions and receive the compressed air.

A compressed air drying device that dries compressed air discharged from a compressor includes a dryer and a controller. The dryer includes a drying container, which is filled with a desiccant, and a discharge valve arranged in a discharge port that discharges drainage produced by regeneration of the desiccant. The controller obtains an ambient temperature and controls opening and closing of the discharge valve. When the ambient temperature is a temperature at which freezing occurs, the controller moves the compressed air, which is discharged from the compressor and heated, into the dryer and restricts opening of the discharge valve.

An imaging device includes an imaging unit, a first change amount calculating unit, and a second change amount calculating unit, and a control unit. The imaging unit continuously performs imaging to generate images of a plurality of frames of which the resolution is any one of a plurality of resolutions. The first change amount calculation unit calculates a first change amount that is an information change amount of the images of a plurality of frames. The second change amount calculation unit calculates a second change amount that is a temporal change amount of the first change amount. The control unit controls a resolution of the imaging unit on the basis of a result of comparing the second change amount with a threshold value and a result of discriminating a sign of the second change amount.

A parking brake system for electrically controlling a parking brake of a vehicle is provided. The parking brake system includes a parking brake provided for each wheel, an air dryer controller, and an actuator. The air dryer controller is provided to an air dryer to electrically control the parking brake. The air dryer dries compressed air for use in the parking brake. The actuator is provided for each axle of the wheel to actuate the parking brake with the compressed air in accordance with an electric signal from the air dryer controller.

Parking brake system

The operation of an air compressor is controlled to control engine performance to thereby improve the performance of the vehicle. A compressor () driven by an engine () of a vehicle and supplying compressed air to loads (-) is controlled by an ECU (). A loaded state and an unloaded state of the compressor () are switched between each other according to the requirements from the loads (-). When the vehicle requires braking force, the compressor () is set to the loaded state irrespective of the requirements from the loads (-).

Compressed air supply system, compressed air supply device for vehicle, and method of controlling air compressor

Disclosed is a vehicle compressed air supply device, comprising pressure maintenance valves for service brakes, which are positioned between a junction chamber and compressed air channels for primary brakes; a pressure maintenance valve for the parking brake, which is positioned between the junction chamber and a compressed air channel for the parking brake; and a pressure maintenance valve, positioned on a supply path that connects the pressure maintenance valve for the parking, brake with the junction chamber, and which is closed until the pressure of the compressed air that is supplied to the compressed air channels for the primary brakes reaches a prescribed pressure value. The pressure maintenance valve has the same structure as the pressure maintenance valves for service brakes and the pressure maintenance valve for the parking brake.
