In this embodiment, control as stopping compressor 4 performed in order to improve maneuverability, will describe: stopping when (1) gives it the gun controls (in order to improve acceleration)；(2) stopping during full-throttle driving controls (in order to improve the acceleration when accelerator standard-sized sheet)；And the stopping that (3) are when guaranteeing to brake negative pressure controls (in order to improve brake boost ability).
Car air-conditioner controls the temperature of vaporizer in the table shown in the device 38 (A) according to Fig. 2 and obtains factor alpha, to calculate storage cold, and when obtaining factor alpha, utilize by the formula of the Time Calculation storage cold of the factor alpha obtained and the temperature keeping vaporizer, calculating storage cold (%): storage cold (%)=storage cold (last time) (%)+factor alpha × time (second).
Car air-conditioner control device 38 is by the storage cold (%) calculated, and according to the table shown in (B) of Fig. 2, calculates current storage cold water flat (such as, 1 to 7).In this example embodiment, if the temperature of vaporizer exceedes threshold value A (DEG C), then will store up cold (%) and be set as 0(%) (control function 1).
In car air-conditioner controls device 38, by the accelerator opening that current storage cold water is put down, accel sensor 31 detects in the cold element 13 of storage of the vaporizer 8 obtained according to control function 1 and the speed that vehicle speed sensor 32 detects, stop condition when giving it the gun of regulation control function 2 setting；According to the storage gentle accelerator opening of cold water, the stop condition when standard-sized sheet that regulation control function 3 sets travels；The braking negative pressure that flat, speed and braking B/P EGR Back Pressure Transducer EGR 33 detect according to storage cold water, stop condition during negative pressure that what regulation control function 4 set guarantee to brake；And utilize the on/off signal of air-conditioning switch 30, according to when giving it the gun to when judgement, the full-throttle driving of stop condition to the judgement of stop condition, guarantee to brake negative pressure time to the judgement of stop condition and control function 5, the stop condition of regulation compressor 4, compressor 4 is performed to stop controlling by compressor stop control 40.
Therefore, current storage cold water according to the vaporizer obtained by the temperature of vaporizer is flat (control function 1), the time of the stop condition (control function 4) of the compressor 4 when car air-conditioner controls the stop condition (control function 3) of the compressor 4 when device 38 changes stopping control (control function 2), the full-throttle driving meeting the compressor 4 when giving it the gun respectively and guarantees to brake negative pressure, and the stopping extending compressor 4 controls the time (control function 5), thus improve maneuverability, the deterioration of cooling performance is suppressed to minimum simultaneously.
When giving it the gun in the stopping control of compressor 4, car air-conditioner control device 38, by the table shown in (B) of Fig. 4, is put down according to storage cold water, is set threshold value B of speed situation；By the table shown in (C) of Fig. 4, put down according to storage cold water, set threshold value C of accelerator opening situation；And set threshold value D lasted after the situation of situation and " accelerator opening>threshold value C " meeting " speed<threshold value B ".As shown in (A) of Fig. 4, car air-conditioner control device 38, according to threshold value B, threshold value C and threshold value D, determines and meets the stop condition (stop condition when hereinafter referred to as giving it the gun) of compressor 4 when being still unsatisfactory for giving it the gun.(control function 2)
If it is determined that occupant wishes acceleration, when then giving it the gun, the control that stops of compressor 4 is by making compressor 4 stop improving the control of acceleration, and when speed is less than predetermined value (threshold value B), according to its threshold value, determine whether occupant makes accelerator opening open more than predetermined value (threshold value C).When giving it the gun in the stopping control of compressor 4, owing to storage cold water flat (1 to 7) is high, so threshold value B of speed and threshold value C of accelerator opening are set to easily to meet the numerical value of stop condition.
If start the program (100) performing to determine the satisfied stop condition being still unsatisfactory for when giving it the gun, as it is shown in figure 5, then car air-conditioner control device 38 determines whether the stop condition (101) when not met gives it the gun.
If it is determined that (101) being "Yes" (being unsatisfactory for condition), then equal threshold value B(102 obtaining speed condition according to storage cold water), threshold value C(103 obtaining accelerator opening condition is equalled according to storage cold water), and judge that whether speed is less than threshold value B(104).
If it is determined that (104) being "Yes" (less than threshold value B), then judge whether accelerator opening exceedes threshold value C(105).
If it is determined that (105) being "Yes" (more than threshold value C), then it is judged to meet the stop condition (106) when giving it the gun, and returns judgement (101) (107).
Simultaneously, if being "No" in the judgement (101) about the stop condition being unsatisfactory for when giving it the gun, then meet the stopping intervalometer timing (measure over time and carry out) (108) when giving it the gun lasted after condition " speed<threshold value B " and condition " accelerator opening>threshold value C " for measurement, and judge to last whether be less than threshold value D(109).

In addition, if being whether "No" (more than threshold value B) less than the judgement (104) of threshold value B about speed, it is "No" (below threshold value D) in the judgement (105) exceeding threshold value C about accelerator opening, and it is being "No" (more than threshold value D) about the judgement (109) lasted less than threshold value D, then the time measured value stopping intervalometer when giving it the gun is reset to 0(111), determine the stop condition (112) being unsatisfactory for when giving it the gun, and return judgement (101) (107).
During the stopping carried out compressor 4 when full-throttle driving controls, car air-conditioner controls device 38 by the table shown in (B) of Fig. 6 according to storing up threshold value E of cold level set accelerator opening condition, and sets threshold value F lasted after meeting condition " accelerator opening > threshold value E ".As shown in (A) of Fig. 6, utilize threshold value E and threshold value F, it is determined whether the stop condition (hereinafter referred to as stop condition during full-throttle driving) (control function 3) of compressor 4 when meeting full-throttle driving.
If it is determined that occupant wishes that acceleration maximizes, then during full-throttle driving to compressor 4 stop control to be by making compressor 4 stop acceleration to bring up to the highest control, and determine whether occupant makes accelerator opening open sizable value (threshold value E).When full-throttle driving in the stopping control of compressor 4, owing to storage cold (1 to 7) calculated is high, so threshold value E of accelerator opening is set as easily meeting the value of stop condition.
If starting to perform for determining the program (200) meeting stop condition when being still unsatisfactory for full-throttle driving, as it is shown in fig. 7, then car air-conditioner controls the stop condition (201) when device 38 determines whether to meet full-throttle driving.
If being "Yes" (being unsatisfactory for condition) judging (201), then put down according to storage cold water, it is thus achieved that threshold value E(202 of accelerator opening condition), and judge that whether accelerator opening is more than threshold value E(203).
If being "Yes" (more than threshold value E) judging (203), it is determined that meet the stop condition (204) during full-throttle driving, and return judgement (201) (205).
Simultaneously, if being "No" (meeting condition) in the judgement (201) about stop condition when being unsatisfactory for full-throttle driving, then for the stopping intervalometer timing (measure over time and carry out) (206) when lasting the full-throttle driving measured after meeting condition " accelerator opening > threshold value E ", and judge whether to last less than threshold value F(207).
If being "Yes" (less than threshold value E) judging (207), it is determined that for meeting the stop condition (208) during full-throttle driving, and return judgement (201) (205).
In addition, if being "No" (below threshold value E) about accelerator opening more than the judgement (203) of threshold value E, and it is being "No" (more than threshold value E) about the judgement (207) lasted less than threshold value F, then it is reset to 0(209 by stopping the intervalometer time measured value when full-throttle driving), it is defined as being unsatisfactory for the stop condition (210) during full-throttle driving, and returns judgement (201) (205).
In the stopping of compressor 4 being controlled when guaranteeing to brake negative pressure, car air-conditioner controls device 38 and is guaranteed threshold value G of condition by the table shown in (B) of Fig. 8 according to storing up cold level set braking negative pressure, and sets threshold value H lasted after meeting condition " braking negative pressure < threshold value G ".As shown in Fig. 8 (A), utilize threshold value G and threshold value H, determine the stop condition (hereinafter referred to as guaranteeing to brake stop condition during negative pressure) (control function 4) meeting compressor 4 when being still unsatisfactory for guaranteeing to brake negative pressure.
The braking negative pressure at main rear portion is used as when trampling brake pedal in the case of function to pedal force power-assisted occupant, when guaranteeing to brake negative pressure, the stopping of compressor 4 controls to determine that whether braking negative pressure is less than predetermined value (threshold value G), thus prevent from not providing assist function because braking negative pressure is not enough, if and brake negative pressure less than predetermined value (threshold value G), then by making compressor 4 stop, it is ensured that braking negative pressure.When guaranteeing to brake negative pressure in the stopping control of compressor 4, if the storage cold water calculated flat (1 to 7) is high, then threshold value G of braking negative pressure is set as easily meeting the numerical value of stop condition.In this example embodiment, it is weak to close to atmospheric pressure that braking negative pressure means to brake negative pressure less than the situation of predetermined value (threshold value G) (braking negative pressure < threshold value G), and the state of non-threshold G.
If start to perform for determining the program (300) meeting stop condition when being still unsatisfactory for guaranteeing to brake negative pressure, as it is shown in figure 9, then car air-conditioner control device 38 determines whether to meet the stop condition (301) when guaranteeing to brake negative pressure.
If being "Yes" (being unsatisfactory for condition) judging (301), then equal acquisition braking negative pressure according to storage cold water and guarantee threshold value G(302 of condition), and judge whether to brake negative pressure less than threshold value G(303).
If being "Yes" (less than threshold value G) judging (303), it is determined that meet the stop condition (304) when guaranteeing to brake negative pressure, and return judgement (301) (305).
Simultaneously, if being "No" (meeting condition) in the judgement (301) about stop condition when being unsatisfactory for guaranteeing braking negative pressure, the stopping intervalometer timing (measure over time and carry out) (306) lasted after measurements meets condition " braking negative pressure < threshold value G " when then guaranteeing to brake negative pressure, and judge to last whether be less than threshold value H(307).
