In a fuel cell system 20 mounted on a fuel cell vehicle of the invention, water separated by a gas-liquid separator 38 included in a hydrogen supply system and by a gas-liquid separator 48 included in an air supply discharge system 40 is temporarily accumulated in buffer tanks 62a through 62c, which are set inside a front fender or inside a front bumper of the vehicle. The accumulated water is released from water outlets 64b and 64c located forward and backward a front wheel of the vehicle having relatively little potential effects of vehicle wind or air flow caused by motion of the vehicle. For the purpose of reducing the potential effects of the vehicle wind on the released water, the fuel cell vehicle may have an air flow path that makes the released water flown obliquely backward the vehicle by the air flow or form an air curtain of exhaust gas or the air ahead of the released water. This arrangement effectively restricts the released water from being scattered by and swirled on the vehicle wind and thereby prevents potential troubles such that the released water is scattered on other vehicles running on the side and behind.

A light access can be integrally formed with a light guide on at least one end of the light guide. A printed circuit board with an LED lamp mounted thereon can be press-fitted in the light access for transient arrangement, and can be fixed by a cover. The position of the printed circuit board can be determined in relation to the light guide. For example, engagement hooks of the light access can be fitted with recesses in the printed circuit board for positioning the circuit board in a plane normal to the longitudinal direction of the light guide. Similarly, positioning ribs of the light guide can be employed for positioning in the longitudinal direction of the light guide. The light guide can be formed in an almost rod shape having four sides in section normal to the longitudinal direction of the light guide. A light guide lens can be formed in one surface and a diffuser cut can be formed in the opposite surface of the light guide.

A vehicle travel control apparatus makes an own vehicle automatically follow a vehicle in front by setting a target acceleration/deceleration G0 using travel data expressing behavior of the vehicle, travel environment, driving operations and others. Here, during vehicle travel based on driver control, multiple travel data are sampled a predetermined number of times to perform multiple regression analysis on that sampled data. Preference data expressing preferences of the driver (multiple regression coefficients) are thereby obtained, and target acceleration/deceleration computation data are updated using these multiple regression coefficients. As a result, it is possible to control the behavior of the vehicle in accordance with preferences of the driver during automatic following control execution.

摘要:
An apparatus for the domestic cogeneration of heat and electrical energy utilizing an inverted Brayton cycle gas turbine, a combustion chamber, an electrical generator and a compressor. Combustion air is preheated in a heat exchanger by gaseous combustion gases or exhaust gases exiting from the turbine. The combustion air is supplied at substantially atmospheric pressure to the combustion chamber where fuel is burned. The cooled gaseous combustion gases exiting from the heat exchanger are then fed to the compressor where they are recompressed to atmospheric pressure, and are finally used to heat the working fluid of a domestic heating system before being exhausted to the atmosphere. The apparatus can also include an acoustically and thermally insulated housing, an electric air blower for start-up, an engine ignition device, a frequency converter which conditions the electric generator output for connection to the main supply and a control system which is cooled by the engine intake air and which detects thermal and electrical demand and adjusts the engine power accordingly.

摘要:
An anti-skid brake control assembly for controlling brake pressure which is first quickly reduced when a skid condition occurs or is about to occur and in which the reduced brake pressure is restored to resume the braking operation. During restoration of the braking pressure, the pressure is first rapidly increased and then more gradually increased thus preventing a skid condition from being repeated rapidly.

An antiskid control system includes a hydraulic pressure control device connected between a braking hydraulic pressure source and wheel cylinders. The hydraulic pressure control device has a variable volume chamber adapted to cyclically vary the hydraulic brake pressure applied to the wheel cylinders from the braking hydraulic source and a valve adapted to control both the hydraulic pressure communication between the variable volume chamber and the wheel cylinders, and the hydraulic pressure communication between the braking hydraulic pressure source and the wheel cylinders. The variable volume chamber and the valve are also independently actuated in response to the sensed braking conditions of the wheel.
