When in the 1 operation the temperature inside is maintained at target temperature by an evaporator, the cooling power of the evaporator is increased so as to carry out the 2 operation for temperature inside lowering. When in the 2 operation the temperature inside reaches lower limit temperature (Tmin), the compressor stops so as to carry out the 3 operation. When in the 3 operation the temperature inside reaches upper limit temperature (Tmax), the compressor restarts so as to carry out the 1 operation.

A method controls a recirculation position of a return vent in an HVAC system for a vehicle with a compressor driven by a start/stop engine. A partial s recirculation position is set according to a basic recirculation strategy while the engine is operating. An auto stop event is entered at a time with the compressor operating. A full recirculation position is set during the stop event if a plurality of low fogging probability indicators are true. The low fogging probability indicators include a sensed ambient temperature being above a predetermined temperature, a sensed state of a windshield wiper being an off state, and a sensed sunload being above a predetermined sunload.

A driving support system for use in a vehicle uses a headlight controller for directing a headlight beam on a road surface in an intersection when the vehicle stops at the intersection. Another vehicle simultaneously approaching the intersection detects the beam of the surface with an image sensor and processor of the driving support system. The system of the another vehicle sends back a vehicle ID signal to the stopping vehicle when a predetermined beam pattern is recognized by the processor. Then, the system uses a buzzer for notifying a driver of the stopping vehicle that the ID signal has been returned.

A control method of a vacuum power-assisted braking system of an electric automobile comprises the following steps of detecting igniting signals, and executing the next step if the igniting signals are detected, or else a vacuum pump is not started; detecting braking signals and pressure of an air storage tank, wherein the vacuum pump works and a bit zone is determined to be true if the braking signals are detected or the pressure of the air storage tank is higher than a higher limit value, or else a next step is executed; and detecting the bit zone and the pressure of the air storage tank, wherein the vacuum pump works and the bit zone is determined to be true if the bit zone is detected to be true and the pressure of the air storage tank is no higher than a lower limit value, or else the vacuum pump stops working and the bit zone is determined to be false. Compared with the prior art, the control method of the vacuum power-assisted braking system of the electric automobile considers the braking signals to be a first condition for judging whether the vacuum pump is started or not, and avoids the condition of insufficient vacuum degree of the air storage tank caused by continuous stepping on a braking pedal when a downward slope is met.

A dive computer system that utilizes a direct skin temperature measurement is provided. The dive computer system includes a measurement device that includes a temperature sensor and is attached to a strap. The strap is placed around a diver's chest and configured to measure the diver's skin temperature. The skin temperature is wirelessly transmitted to a dive computer that utilizes a dive algorithm to determine compartment inert gas saturation and desaturation. The dive algorithm determines an updated skin perfusion factor that is in turn utilized to determine an updated half time for the skin compartment for inert gas desaturation and a pressure tolerance for the skin compartment for inert gas saturation.

A catalyst having an oxygen storage capacity is provided in an exhaust passage of an internal combustion engine. A catalyst temperature calculating device calculates an oxygen storage amount of the catalyst to a value greater than or equal to zero and less than or equal to than a maximum value based on an amount of oxygen and an amount of unburned fuel components in a fluid flowing into the catalyst. A temperature calculation process calculates a temperature of the catalyst assuming that an amount of temperature rise of the catalyst is larger when an increase amount of the oxygen storage amount is large than when the increase amount of the oxygen storage amount is small in a case where the oxygen storage amount increases.
