Problems solved by technology
For example, in windy weather, due to the large air pressure difference inside and outside the car, the door will generate an outward moment. When the passenger pulls the door latch, the door will burst open suddenly; or in windy weather and the door is halfway open. When the car is opened, the wind force outside the car will also cause the door to generate an outward (or inward) moment, making the door in an unstable state

The invention discloses a control system for a car door. The control system is characterized in that a PI (proportion and integration) automatic control system is used for calculating an air pressure difference between the inside and outside air pressures of the car door according to electric signals transmitted from inside and outside pressure sensors inside and outside the car door and controlling a torque generator to generate an auxiliary force for the car door to balance an adverse torque generated for the car door by air; after a door closing signal of a remote controller is received by a remote control receiver of the PI automatic control system, the torque generator is driven to generate a door closing torque to finish a door closing action. Due to the adoption of the structure, the purpose of stably opening or closing the car door in different states is achieved.
Description
technical field [0001] The invention relates to the field of automatic control of automobiles, in particular to a control system for automobile doors. Background technique [0002] With the improvement of living standards, people's demand for cars is increasing, and the quality requirements for cars are also getting higher and higher. However, in terms of the functional design of the automobile door, it is only satisfied with the simple switchable requirement. The connection of automobile doors on the market now basically adopts a direct and simple hinge solution. [0003] Although the above scheme has the advantages of simple structure, convenient installation, good economy, etc., there are some safety problems. For example, in windy weather, due to the large air pressure difference inside and outside the car, the door will generate an outward moment. When the passenger pulls the door latch, the door will burst open suddenly; or in windy weather and the door is halfway op...
