摘要:
This invention has as its object to provide a method and apparatus for controlling a vehicle air conditioner, which can obtain a combination of an outlet air flow rate V a and an outlet air temperature T o , which is desirable for comfort of a passenger, under a condition of air-conditioning control based on a heat balance equation. In order to achieve this object, this invention provides a method of controlling a vehicle air conditioner, which controls the outlet air flow rate and the outlet air temperature of air-conditioning air while balancing between the heat amount supplied from an air conditioner for adjusting the air-conditioning air into a passenger room, and the heat load acting on a vehicle, including the first step of obtaining, from a heat balance equation, a plurality of combinations of the outlet air flow rates V a and the outlet air temperatures T o necessary for maintaining the passenger room temperature to be a predetermined target temperature, the second step of calculating comfort indices each representing the comfort level of a passenger on the basis of state amounts of factors which influence comfort felt by the passenger in the passenger room, and the plurality of combinations of the outlet air flow rates V a and the outlet air temperatures T o obtained in the first step, and the third step of searching a combination of the outlet air flow rate and the outlet air temperature, which can provide a comfort index closest to an optimal value of the comfort indices calculated in the second step.
摘要:
In a vehicle equipped with an air conditioning system (1) including a heat exchanger for heating or cooling supply air to a cabin of the vehicle by heat exchange with heat transfer medium supplied from an accessory (6, 8) driven by a vehicle engine, a value relating to the capability of the heat transfer medium to heat or cool the supply air is detected, and the engine is automatically stopped for a predetermined period when the vehicle is stopping, the air conditioning system ( 1 ) is in operation and the detected value meets a specified condition (a condition that the engine cooling water temperature is equal to or higher than a specified temperature).

摘要:
A controlling circuit for a motorcar front window wiper accommodating apparatus of a concealed type wherein a wiper is accommodated within an opening portion (2) provided between the front window lower edge and the bonnet rear-end edge (F), the opening portion is opened and closed by the cowl cover (4), to a controlling circuit for interlockingly controlling the operation between the cowl cover (4) and the wiper (3). It is adapted to operatively cooperate the opening and closing operations of the cowl cover (4) with the wiper (3), to actuate the wiper (3) when the cowl cover (4) reaches the position where it does not interfere with the lifting wiper wiping portion to be lifted in the position before it reaches its fully open position in the opening process of the cowl cover (4) so as to retain the speediness of the wiper actuation to remove the delay feeling for improving the safety.
