  • Publication number: 20150160071
    Abstract: Provided are a vibration detector and a vibration detecting method, which are power saving, can detect vibration even if the vibration is very weak, and can perform both start-up of the apparatus and collection of data of vibration information by the use of only one sensor. The apparatus includes a vibration detector, a semiconductor switch, a controller and a power supply. The semiconductor switch and the controller are connected to the power supply. The vibration detector detects vibration and consequently generates a vibration voltage. The semiconductor switch includes a voltage divider for generating a bias voltage inside. The semiconductor switch detects a voltage produced by superposing the bias voltage onto the vibration voltage outputted from the vibration detector, and conducts current when the detected voltage is equal to or larger than a certain value. The controller wakes up with the current conducted by the semiconductor switch as a trigger signal.

  • Publication number: 20150107363
    Abstract: A piezoelectric vibration sensor includes a piezoelectric element which is in a form of flat plate, an element holding plate which is in a form of flat plate, and first and second support members. An electrode is arranged on at least one plane of the piezoelectric element. The piezoelectric element is joined to one plane of the piezoelectric element. The first support member and the second support member support the piezoelectric element and the element holding plate. A vibration film activates vibration of the element holding plate between the first support member and the second support member. Moreover, the element holding plate is joined to each of the first support member and the second support member through the vibration film. As a result, it is possible to obtain high sensitivity in a wide frequency range and to withstand an impact which is added from the outside.

  • Publication number: 20150001917
    Abstract: A braking device for a vehicle is provided which includes a servo unit working to develop a hydraulic pressure which generates a braking force. The servo unit is actuated following movement of a movable member to develop the hydraulic pressure. The movable member moves in response to a braking effort. The braking device has an elastic member working to create resistance to the movement of the movable member relative, so that the resistance is different between when the movable member moves in a frontward direction and when the movable member moves in a backward direction. This produces a hysteresis in relation of the brake effort to the amount of movement of the movable member.

  • Publication number: 20150001918
    Abstract: A braking device for a vehicle is provided which includes a master cylinder, a pedal return spring, and a movable member. When a brake pedal is depressed, it is transmitted to the master cylinder through the pedal return spring to develop a braking force. The movable member is disposed between the pedal return spring and the master cylinder and works to absorb deformation of the pedal return spring arising from tilting thereof when the brake pedal is depressed and swings, thereby ensuring the stability in motion of the brake pedal.

  • Publication number: 20150001915
    Abstract: A braking device for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force. The hydraulic booster includes a fluid chamber and a throttle. When a brake pedal is depressed suddenly, the throttle works to obstruct or restrict an outflow of brake fluid from the fluid chamber, thereby increasing the pressure in the fluid chamber. This causes the pressure in a master chamber of the hydraulic booster to rise, thereby producing the frictional braking force almost no later than start of the depression of the brake pedal.

  • Publication number: 20150000266
    Abstract: A braking device for a vehicle is provided which is equipped with a hydraulic booster. The hydraulic booster includes a master cylinder, a braking simulator, and an input piston. The input piston is disposed in the master cylinder in connection with a brake actuating member such as a brake pedal and is moved in response to a braking effort applied to the brake actuating member to drive a spool valve which switches among a pressure-reducing mode, a pressure-increasing mode, and a pressure-holding mode. The braking simulator works to urge the input piston rearward and is disposed inside a cylindrical cavity of the master cylinder of the hydraulic booster. This layout improves the mountability of the braking device in vehicles.

  • Publication number: 20150001920
    Abstract: A braking device for a vehicle is provided which includes a braking simulator, thus resulting in improved mountability of the braking device in the vehicle. The braking device is designed to permit component parts of the hydraulic booster to slide on one another in response to a braking effort on a brake pedal, thereby absorbing an undesirable load on the braking device and also ensuring the stability in operating the brake pedal. This results in improved durability and maneuvering feeling of the braking device.

  • Publication number: 20150001916
    Abstract: A braking device for a vehicle is provided which includes a power fail-safe mechanism which works to create frictional braking force at a wheel of the vehicle in the event of loss of electric power. The braking device is equipped with an electromagnetic valve which is of a normally closed type. In the event of loss of electric power in the braking system, the electromagnetic valve is closed to block fluid communication between a hydraulic booster and a brake fluid reservoir, so that a stroke chamber in the hydraulic booster is hermetically closed. This enables the pressure in a master cylinder to rise in response to depression of a brake pedal to develop the frictional braking force.

  • Publication number: 20150001921
    Abstract: A braking device for a vehicle is provided which is equipped with a hydraulic booster in which a hydraulic pressure chamber is formed. The hydraulic booster has a plurality of fluid flow paths which are shaped to create convective spiral flows of brake fluid to flush bubbles of air into the spiral flows of brake fluid every braking operation. The mixture of the bubbles of air and the brake fluid is then delivered to a reservoir. The bubbles of air are discharged outside the reservoir, thereby purging the hydraulic booster of air completely.

  • Publication number: 20150001919
    Abstract: A braking device for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force, a solenoid valve installed in a flow path connecting between a brake fluid accumulator and a servo chamber of the hydraulic booster, and a collision avoidance controller. When determining that there is a risk of a collision with an obstacle, the collision avoidance controller opens the first solenoid valve to achieve emergency braking to minimize the risk of the collision. Basically, the emergency braking is achieved only using the solenoid valve, thus allowing an emergency avoidance mechanism of the braking device to be constructed with a minimum of equipment and facilitating the mountability of the braking device in vehicles.
