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 value of the feedback terminal is the AD value corresponding to the 0.1V voltage, and the feedback terminal is short-circuited The voltage value 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 value, 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 value of t...

Abstract

The invention relates to a method for controlling the time operation of a DC motor of a vehicle-mounted air conditioner controller. End open-circuit voltage position, feedback end short-circuit voltage position and the running distance of each cycle, read the current DC motor feedback end voltage position, (2) motor start judgment, (3) motor operation, (4) motor time learning, using the above The technical solution, the present invention provides a method for controlling the time operation of the DC motor of the vehicle-mounted air conditioner controller, regardless of whether the DC motor has a feedback terminal, and regardless of whether the feedback terminal fails, the DC motor can continue to run according to the time, thereby ensuring that the vehicle The air conditioning system can work normally, which improves the safety factor of driving.

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...
