Problems solved by technology

However, there are many target positions for mode and temperature motor adjustment, and they all have a feedback terminal. Once the feedback terminal fails, the current operating position of the motor will not be known, resulting in the inability to continue running
The vehicle air conditioning system cannot work normally, and serious situations will cause driving safety accidents, such as the air conditioning control system cannot blow and defrost normally, blocking the driver's sight and causing traffic accidents

Embodiment Construction

[0036] Such as Figure 1-3 As shown, a method for time-running control of a DC motor of a vehicle-mounted air-conditioning controller comprises the following steps:

[0037] (1) Start the system and configure the parameters of the DC motor. Among them, the minimum starting distance is 8 AD values, the minimum braking distance is 8 AD values, the open circuit voltage position of the feedback terminal is the AD value corresponding to the 0.1V voltage, and the feedback terminal is short-circuited The voltage position is the AD value corresponding to the 4.5V voltage. The running distance of each cycle is (1000*full AD value)*5 / running time (in milliseconds). To read the current DC motor feedback terminal voltage position, it mainly includes the following steps :

[0038] (a1) First determine whether the DC motor has a feedback terminal, if there is a feedback terminal, then enter step (a2), if there is no feedback terminal, then enter step (a4);

[0039] (a2) Read the voltage v...

Abstract

The invention relates to a time running control method of a DC motor of a vehicle-mounted air conditioning controller, including the following steps: (1) System Startup, the parameters of DC motor areconfigured, A DC motor paramete includes a minimum start distance, Minimum brake distance, Open-circuit voltage position on feedback side. The position of the short circuit voltage at the feedback terminal and the distance traveled per cycle. Read the current DC motor feedback terminal voltage position, (2) judging the starting of the motor, (3) Motor operation, (4) motor time study, the adoptionof that technical scheme, The invention provides a time running control method of a DC motor of a vehicle-mounted air conditioning controller, which can continue to run according to time regardless of whether the DC motor has a feedback end and whether the feedback end is malfunctioning, thereby ensuring that the vehicle-mounted air conditioning system can work normally and improving the drivingsafety factor.

Description

technical field [0001] The invention relates to a control method of a direct current motor, in particular to a time running control method of a direct current motor of a vehicle-mounted air conditioner controller. Background technique [0002] Vehicle air conditioner controllers include mode motors, internal and external circulation motors and temperature motors. Many of these motors use DC motors, generally including positive, negative and feedback terminals. The motor is controlled to run in a predetermined direction through the difference in the level of the positive pole and the negative pole, and the position of the motor is confirmed according to the voltage of the feedback terminal. In addition, some internal and external cycle DC motors do not have a feedback terminal, because there are only two positions in operation, and they are directly based on the time. The whole run is different, but the running direction is different. If the inner loop goes the whole way in t...
