The utility model is realized by following technical proposal: air-conditioning work alarm device during a kind of auto idle speed, this device comprises be used to rotating speed of automobile engine is provided, the CAN bus of the speed of a motor vehicle and throttle position, it is characterized in that, described CAN bus is connected with controller, described controller is used for receiving the rotating speed of automobile engine on the CAN bus, the speed of a motor vehicle and throttle position signal also judge whether vehicle is in idling mode, described controller be connected with for send on-board air conditioner whether start signal the A/C switch and be used for judging the alarm unit that vehicle gives the alarm when being in idling mode and on-board air conditioner work at controller.
Controller receives the information of rotating speed of automobile engine, the speed of a motor vehicle and throttle position by the CAN bus, and above-mentioned information processed judge whether automobile is in idling mode, receive the signal whether air-conditioning that the A/C switch sends is opened with Time Controller, when automobile is in idling mode and air-conditioning when in running order, controller sends control signal to alarm unit, and on-board air conditioner was still in work when alarm unit gave the alarm the reminding driver auto idle speed.
In the air-conditioning work alarm device, described controller also is connected with for the timekeeping circuit of judging that at controller automobile carries out timing when being in idling mode and on-board air conditioner work when above-mentioned auto idle speed.The control time meter began timing when controller was in idling mode and on-board air conditioner work at automobile.Controller by the timing of timekeeping circuit judge automobile when the idling mode on-board air conditioner work how long.
In the air-conditioning work alarm device, described controller is preset with time value when above-mentioned auto idle speed, and described controller also is used for controlling alarm unit when the time of timekeeping circuit timing surpasses controller Preset Time value and gives the alarm.Controller control timekeeping circuit begins timing and receives simultaneously the time value that timekeeping circuit sends, and the time value that time value and the controller of technology circuit transmission are preset compares, when the time value of timekeeping circuit transmission surpasses controller internal preset time value, controller sends control signal to alarm unit, and alarm unit gives the alarm.Can prevent that like this air-conditioning work of the long-time Parking idling of autoist from causing the fuel oil waste, avoids the safety misadventure that have the people to sleep and may cause this moment in the automobile simultaneously in car.
In the air-conditioning work alarm device, described controller is by CAN bus connecting engine ECU when above-mentioned auto idle speed.The information of rotating speed of automobile engine, the speed of a motor vehicle and throttle position that CAN bus transfer Engine ECU sends, controller receives these information by the CAN bus.
In the air-conditioning work alarm device, described controller is micro controller system or the ECU with CAN interface when above-mentioned auto idle speed.Micro controller system and ECU have computing, processing, judgement, the function of output command then, and the micro controller system with CAN interface can receive the signal that the CAN bus sends and process judgement again.
In the air-conditioning work alarm device, described alarm unit comprises buzzer phone or loud speaker when above-mentioned auto idle speed.Alarm unit is used for giving the alarm, and buzzer phone and loud speaker are all lifted the function of sending the sound, play the function of reminding driver as alarm unit with buzzer phone or loud speaker.
Compared with prior art, the air-conditioning work alarm device has the following advantages during this auto idle speed:
1, the utility model receives the signal whether air-conditioning that rotating speed of automobile engine, the speed of a motor vehicle and throttle position signal that the CAN bus sends and A/C switch send works by controller, can determine automobile when idling air-conditioning whether still in work.
2, the utility model is when automobile is in Parking idling mode and air-conditioning work, the time value that controller sends at timekeeping circuit is during greater than controller internal preset time value, the control alarm unit gives the alarm, and reminds the occupant to close air-conditioning and avoids causing the fuel oil waste and avoid in the automobile have the people to sleep in car this moment and may cause the safety misadventure of suffocating.
Description of drawings
