Abstract: A stabilizer bush includes a cylindrical body section including a through-hole into which the stabilizer is inserted. In the body section, a slit is continuously formed from an outer circumferential surface of the body section toward an inner circumferential surface of the through-hole, and is formed so as to extend along a full length of the body section in a center axis direction of the through-hole. A direction of the slit from the outer circumferential surface toward the inner circumferential surface is set to a direction which does not pass through the center of the through-hole, and the slit is formed so as to extend parallel to a center axis of the through-hole.

Abstract: An air conditioning system for vehicles includes a restriction control device that reduces the consumptive power of the air conditioning system by reducing the cooling ability of the air conditioning system when a cooling load of an interior of the vehicle has increased over a predetermined level, and when predetermined conditions are satisfied. In the system of the present invention, a water temperature sensor or a switch for detecting the opening of a roof window or a double sliding window is not necessary. In the present invention, under certain predetermined conditions, the power to an air conditioner may be appropriately restricted and the amount of heat radiation at the condenser may also be appropriately restricted. Consequently, the control may reduce waste power to prolong the life of equipment, and which may achieve an improved and comfortable air conditioning state, even when a roof window or a double sliding window is open.

Abstract: An air conditioning system for vehicles includes a sensor for detecting opening and closing of a vehicle portal, such as a door or a window, and a control device for selectively opening ports through which temperature controlled air flows into an interior of a vehicle, in response to a signal generated by the opening and closing detecting sensor and a target air temperature. In the system, even if a door or a window of a cabin is opened, ports are opened according to a most suitable port mode depending on the target air temperature at a present time. Therefore, an improved air conditioning state for an operator, and an improved driving condition with reduced waste power and reduced loads to the respective equipment, may be achieved.

Abstract: An air conditioning system for vehicles has a cooling circuit and a radiator supplying cooling water to an engine. The cooling circuit includes a compressor, a condenser and an evaporator. The system includes a water temperature sensor for detecting a water temperature in the radiator, and a control device for selectively controlling the opening of ports to allow temperature controlled air to flow into an interior of a vehicle, in accordance with the water temperature, detected by the water temperature sensor, and a target conditioned air temperature. In the system, the power to an air conditioner may be appropriately restricted, and the amount of heat radiation at the condenser may also be appropriately restricted. Consequently, the water temperature in the radiator may be prevented from becoming too hot, thereby preventing instances of overheating and preventing a warning of a potential overheat.

Abstract: In a system and method for conditioning air in a vehicle, it is determined whether an inside air temperature detected by an inside air temperature sensor is stable, an outside air temperature is estimated based on the inside air temperature only when the inside air temperature is stable, a target conditioned air temperature is calculated using an estimated outside air temperature as well as the estimation of outside air temperature is repeated, and the estimated outside air temperature used for the calculation of the target conditioned air temperature is renewed only when the estimated outside air temperature is different from a prior estimated outside air temperature by a value more than a predetermined value. The outside air temperature is adequately estimated without providing an outside air temperature sensor. Consequently, a desirable air conditioning for vehicles may be performed simply and inexpensively.
