Abstract

PURPOSE:To actually regulate the sensitivity or the response of an air pollution sensor by changing supply mode of open air and inside air in accordance with conditions extracted from both an air pollution sensor and a tunnel sensor which detects presence of a tunnel. CONSTITUTION:Detecting signal of an air pollution sensor 1 and a tunnel sensor 2 are guided by a logic circuit 3, from which an output signal suitable for and condition is transmitted to the following steps. That is, when a tunnel is sensed and open air which is polluted is also sensed, an output signal is sent to an amplifier circuit 4. An electric actuator 6 which changes an inside/ open air changing damper 5 from an open air supply position to an inside air supply position is operated in response to said output signal. To operate the actuator on AND condition, it is necessary to operate a logic circuit 3 on the AND condition. When it is done so, the inside/open air changing damper 5 will be changed on no condition from the open air supply position to the inside air supply position so that the sensitiveness and the response of the air pollution sensor 1 may be enhanced.

くするように働く。[Function] With this configuration, for example, depending on the logical product condition, the condition that the vehicle is traveling in a tunnel is required, so that the sensitivity or responsiveness of the air pollution sensor is apparently reduced. Depending on the logical sum condition, the inside/outside air switching member is operated unconditionally when traveling in a tunnel, so it works to increase the sensitivity or responsiveness of the sensor.
