Definitions
- the invention relates to a method for controlling an air conditioning system for a vehicle with closable body openings according to the preamble of patent claim 1.
- a method for heating a vehicle in which a distinction is made between the operation with the vehicle closed and the vehicle open.
- the heating system is controlled using the parameters ambient temperature, target interior temperature, actual interior temperature and, if applicable, the vehicle speed. Regulation takes place only if the interior temperature changes over time.
- the blow-out temperature is controlled, i.e. Environmental conditions etc. will not be considered.
- this object is achieved by a method for controlling an air conditioning system for a vehicle with closable body openings according to claim 1.
- Advantageous developments of the invention are specified in the subclaims.
- FIGS. 1A and 1B show a flow chart of the method for climate control according to the invention.
- FIG. 1 is divided into FIGS. 1A and 1B thermally comfortable condition can be achieved for the occupant (s) both when the vehicle is closed and when it is open.
- the method according to the invention in contrast to the prior art, in the case of the open convertible top various information is used as control parameters.
- the conventional, comfortable climate control is carried out when the convertible top is closed.
- the method according to the invention for controlling an air conditioning system for a vehicle with closable body openings also includes Vehicle speed is taken into account as this has a significant impact on the thermal comfort of the occupants.
- the vehicle speed is advantageously determined by means of the sensors which are used anyway for regulating the vehicle dynamics in the vehicle.
- the sensors for detecting the solar radiation and the ambient temperature are already available from conventional air conditioning systems. Therefore, no additional sensors are necessary, so that the method according to the invention achieves an improvement in comfort or a reduction in consumption in a cost-effective or cost-neutral manner.
- a state of a body opening is first detected in a step SO, ie it is determined whether the vehicle is closed or open.
- a conventional air conditioning process is carried out taking into account the parameters of ambient temperature, target interior temperature, actual interior temperature and solar radiation.
- an open roof however, this is as follows
- the inventive method for controlling an air conditioning system described with reference to FIG. 1 with FIGS. 1A and 1B is carried out.
- control according to the invention comprises control sections which take into account the detected parameters of solar radiation, ambient temperature and vehicle speed when regulating the blow-out temperature and the mass flow.

- the air mass flow M can be reduced by a value M q ⁇ 'and the outlet temperature ⁇ A can be kept constant.
- step Q1 If a drop - ⁇ q of the solar radiation compared to a previously recorded solar radiation value is detected (step Q1), the blow-out temperature ⁇ A is increased by a value ⁇ Aq2 and the air mass flow M is kept constant (step Q5). If this increase in the blow-out temperature ⁇ A by the value ⁇ Aq2 is not sufficient to compensate for a temperature reduction by the drop - ⁇ q of the solar radiation (step Q6), the air mass flow M is increased by a value M q2 to support it (step Q7) , In the cooling case, alternatively (not shown), only the air mass flow M can be reduced by the value M q2 'and the blow-out temperature ⁇ A can be kept constant.
- Step T1 the blow-out temperature ⁇ A is reduced by a value S ⁇ $ _ and the air mass flow M is kept constant
- Step T2 If this reduction in the blow-out temperature ⁇ A by the value -9 A s ⁇ is not sufficient to compensate for a temperature increase due to the increase ⁇ u in the ambient temperature (step T3), the air mass flow M is supported by a value M * ⁇ - *. increased (step T4). In the case of heating, alternatively (not shown), only the air mass flow M can be reduced by the value May 'and the outlet temperature ⁇ A can be kept constant.
- Step Tl When a drop - ⁇ u of the ambient temperature from a previously detected ambient temperature is detected (Step Tl), the blow-out temperature ⁇ A is increased by a value ⁇ A 92 and the air mass flow M is kept constant (step T5). If this increase in the blow-out temperature ⁇ A by the value ⁇ A a 2 is not sufficient to compensate for a temperature reduction by the drop in the ambient temperature - ⁇ u (step T6), the air mass flow M is increased by a value MQ 2 (step T7 ) (Heating case). In the cooling case, alternatively (not shown), only the air mass flow M can be reduced by a value Ms 2 'and the blow-out temperature ⁇ A can be kept constant.
- Step VI-H the blow-out temperature ⁇ A is increased by a value ⁇ Av ⁇ and the air mass flow M is kept constant
- Step V2-H If this increase in the blow-out temperature ⁇ A by the value ⁇ Av ⁇ is not sufficient to compensate for a temperature reduction by the increase ⁇ v in the vehicle speed (step V3-H), the air mass flow M is increased by a value M vi to support it (step V4 -H) .
- the air mass flow M is increased by the value M v ⁇ and the blow-out temperature ⁇ A kept constant.
- step VI-H If a drop - ⁇ v of the vehicle speed compared to a previously detected vehicle speed is detected (step VI-H), the blow-out temperature -9 A is reduced by a value - ⁇ Av2 and the air mass flow M is kept constant (step V5-H). If this reduction in the blow-out temperature ⁇ A by the value ⁇ Av2 is not sufficient to compensate for an increase in temperature due to the drop in the vehicle speed - ⁇ v (step V6-H), the air mass flow M is reduced by a value M v2 (step V7 -H) . As an alternative to reducing the blow-out temperature ⁇ A by the value ⁇ Av2 and keeping the air mass flow M constant, only the air mass flow M can be reduced by a value M v2 and the blow-out temperature 9 * A kept constant.
- Step VI-K the blow-out temperature ⁇ A is increased by a value ⁇ Av3 and the air mass flow M is kept constant
- Step V2-K If this increase in the blow-out temperature ⁇ A by the value ⁇ Av3 is not sufficient to compensate for a temperature reduction by the increase ⁇ v in the vehicle speed (step V3-K), the air mass flow M is reduced by a value M v3 (step V4-K).
- the air mass flow M is reduced by the value M v3 and the blow-out temperature ⁇ A kept constant.
- step VI-K If a drop - ⁇ v of the vehicle speed compared to a previously detected vehicle speed is detected (step VI-K), the blow-out temperature - ⁇ A is reduced by a value ⁇ Av and the air mass flow M is kept constant (step V5-K). If this reduction in the blow-out temperature ⁇ A by the value ⁇ Av is not sufficient to achieve a temperature To compensate for the temperature increase due to the drop in the vehicle speed - ⁇ v (step V6-K), the air mass flow M is increased by a value M v in order to support it (step V7-K). As an alternative to reducing the blow-out temperature ⁇ A by the value -9 Av4 and keeping the air mass flow M constant, only the air mass flow M can be increased by a value M v4 and the blow-out temperature ⁇ A kept constant.

- the air conditioning system is then controlled in accordance with the resulting optimized change values for the blow-out temperature and the air mass flow (step S8).
- an occupant-dependent correction value can also be used is also dependent on the degree of activity and / or clothing, which then also additively or subtractively contributes to the optimized blow-out temperature and to the optimized air mass flow. This value can either be set manually or determined by adaptive operation in response to readjustment by the user.
- upper and lower threshold values for the solar radiation q, the ambient temperature ⁇ u and v are additionally defined.
- the above-mentioned characteristic curves are accessed, i.e. an actual value for the regulation is taken into account.
- the upper and lower threshold values are used for access to the trend curves, since regulation in these areas is no longer feasible or the user can no longer feel the effort accordingly.
- the limit values for the radiation at 200W and 1000W, the limit values for the ambient temperature at 5 ° C and 30 ° C and the limit values for the speed at 20km / h and 80km / h are vehicle-dependent and can be significantly higher for very comfortable vehicles.
