<p><P>PROBLEM TO BE SOLVED: To provide a vehicular control device which secures a necessary brake negative pressure and appropriately controls the drive of an auxiliary machine driven by an internal combustion engine. <P>SOLUTION: The vehicular control device 10 is applied to a vehicle 12 provided with an air conditioner 18 driven by the internal combustion engine 14 and a brake booster 30, which increases the braking force of a brake utilizing the intake pressure of the internal combustion engine 14. The vehicular control device 10 includes: an atmospheric pressure sensor 64, which obtains an atmospheric pressure; a negative pressure sensor 66, which obtains the negative pressure in the brake booster 30; a negative pressure threshold value setting part 82, which sets a negative pressure threshold valueΔP0 smaller as the atmospheric pressure obtained by the atmospheric pressure sensor 64 is lower; and an air conditioner drive controlling part 86, which stops or limits the drive of the air conditioner 18 based on a negative pressureΔP obtained by the negative pressure sensor and the negative pressure threshold valueΔP0 set by the negative pressure threshold value setting part 82. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
