Abstract
The utility model belongs to the technical field of automobile air conditionings, particularly relates to an automobile air conditioning control system, which comprises an automobile air conditioning controller, an automobile air conditioning compressor, an engine electronic control unit (ECU), a first relay and a second relay, wherein two connection points of a first relay coil are respectively connected with a 2.03 connection point and a 2.11 connection point of the engine ECU, a second relay coil is connected with the automobile air conditioning controller after being connected with the automobile air conditioning compressor in parallel, a first relay contact and the second relay coil are connected in series, a second relay first contact is connected with the automobile air conditioning compressor in series, and two connection points of a second relay second contact are respectively connected with a 1.04 connection point and a 1.42 connection point of the engine ECU. The automobile air conditioning control system has the beneficial effects that automobiles control a power supply of a compressor to switch on and off according to operation condition, thereby guaranteeing dynamic performance of a finished automobile not to be affected when the temperature of cooling liquid of an automobile engine is high or the finished automobile accelerates quickly.
Description
Technical field
The utility model belongs to the on-board air conditioner technical field, is specifically related to a kind of on-board air conditioner control system.
Background technology
The control of the on-board air conditioner of existing commercial vehicle/comm..vehicle generally is directly to control the vehicle-mounted air conditioner compressor on/off with the on-board air conditioner controller, and can not realize the auxiliary control to on-board air conditioner.Like this, on-board air conditioner in case enable, will be in running state always in the Vehicle Driving Cycle process, and the vehicle motor cooling-liquid temperature is higher or car load is anxious when accelerating when running into, and the problem of dynamic property deficiency of the car load of vehicle will occur.
The utility model content
Technical problem to be solved in the utility model provides a kind of on-board air conditioner control system that can realize the auxiliary control of on-board air conditioner, can control at any time the operation of on-board air conditioner and closes according to vehicle condition.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of on-board air conditioner control system, comprise on-board air conditioner controller and vehicle-mounted air conditioner compressor, also comprise Engine ECU, the first relay and the second relay, the signal of described on-board air conditioner controller accesses described Engine ECU, two contacts of described the first relay coil access respectively 2.03 contacts and 2.11 contacts of described Engine ECU, described the second relay coil with access described on-board air conditioner controller after described vehicle-mounted air conditioner compressor is in parallel, described the first relay contact is connected with described the second relay coil, connect with described vehicle-mounted air conditioner compressor in described the second relay the first contact, two contacts of described the second relay the second contact access respectively 1.04 contacts and 1.42 contacts of described Engine ECU.
The first insurance is set on the described Engine ECU control loop.
The second insurance is set on the described on-board air conditioner controller control loop.
The beneficial effects of the utility model are to adopt Engine ECU control on-board air conditioner, realized the on/off of vehicle according to operating condition control compressor, thereby guarantee higher at the vehicle motor cooling-liquid temperature or car load is anxious when accelerating, the dynamic property of car load can not be affected, thereby has good value for applications.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the schematic diagram of the utility model embodiment on-board air conditioner control system.
The specific embodiment
A kind of on-board air conditioner control system, as shown in Figure 1, comprise on-board air conditioner controller 6, vehicle-mounted air conditioner compressor 9, Engine ECU, the first relay and the second relay, the first insurance 2 is set on the Engine ECU control loop, the second insurance 5 is set on the described on-board air conditioner controller control loop, two contacts of the first relay coil 4 access respectively 2.03 contacts and 2.11 contacts of Engine ECU 1, the second relay coil 7 and vehicle-mounted air conditioner compressor 9 rear and access on-board air conditioner controllers 6 in parallel, the first relay contact 10 is connected with the second relay coil 7, connect with vehicle-mounted air conditioner compressor 9 in the second relay the first contact 8, two contacts of the second relay the second contact 3 access respectively 1.04 contacts and 1.42 contacts of Engine ECU.
When Vehicular system energising, the user opens on-board air conditioner controller 6, and Engine ECU 1 can according to self industrial and mineral condition of vehicle, determine whether relay 1 coil 4 switches on; After 4 energisings of the first relay coil, the first relay contact 10 closures, 7 energisings of the second relay coil, the second relay coil the first contact 8 closures, vehicle-mounted air conditioner compressor 9 energising normal operations, on-board air conditioner normal operation.In the second relay coil first closing of contact, the second relay coil the second contact 3 is also closed, Engine ECU receives air conditioner system and normally moves, detect simultaneously the work of vehicle, operating mode according to vehicle determines whether the first relay coil 4 switches on, thereby realized Engine ECU 1 control the first relay coil 4 break-make vehicle-mounted air conditioner compressors 9 power supplys, it is higher or car load is anxious can cut off air-conditioning compressor 9 power supplys when accelerating and satisfy the car load dynamic property with the power of saving on-board air conditioner consumption to run into the vehicle motor cooling-liquid temperature.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
