Electric control method for automatic outward sliding door system of vehicle

Abstract

The invention provides an electric control method for an automatic outward sliding door system of a vehicle. The automatic outward sliding door system comprises a sliding door body, an electric door lock, a controller, a vehicle speed sensor, and a plurality of motors, wherein both the vehicle speed sensor and the motor are connected with the controller; a lock body of the electric door lock is arranged on a vehicle body; and a lock bolt is arranged on the sliding door body. The electric control method comprises the following steps: the current vehicle speed value and the preset vehicle speedvalue are compared; when the current vehicle speed value is greater than the preset vehicle speed value, the electric door lock is locked; when the current vehicle speed value is less than the presetvehicle speed value, the electric door lock is unlocked; and when the electric door lock is unlocked, a vehicle door motor is controlled to start if the controller receives a triggering signal, and the sliding door body is driven to slidably open and close. The electric control method provided by the invention has the beneficial effects that the start or stop of the vehicle door motor is determined by monitoring the current / voltage during the running of the vehicle door motor and the running time; the adoption of a stepper motor or a displacement sensor and other mechanisms is not needed; andthe control mode is safe and reliable.

Description

technical field [0001] The invention relates to the field of mechanically driven vehicle doors, in particular to an electronic control method for a vehicle automatic outer sliding door system. Background technique [0002] Car doors, especially passenger doors used as passenger access, are an important part of large passenger cars and rail trains. Existing large passenger cars often use inner swing doors and outer swing doors, and rail trains often use smooth sliding doors or sliding doors. [0003] Based on its own design and structure, the inner swing door has problems such as poor sealing, occupying passage space, risk of injury to passengers, and unsightly interior layout. For the outer swing door, although it has the advantage of good sealing performance compared with the inner swing door, because the outer swing door opens to the outside of the car body by a large margin, as a large-capacity vehicle, it is easy to hurt people outside the vehicle, and After the outer ...

Problems solved by technology

At the same time, passenger vehicles (MPV) generally use curved slides, which are embedded in the body and welded. However, there are stressed skeletons on both sides of the door frame of medium and large passenger cars in commercial vehicles. The strength of the body is reduced, which in turn leads to a low safety factor

[0006] Existing folding doors, outer swing doors, inner swing doors, and sliding doors need to be installed with many structures, position sensors need to be installed and adjusted, and even multiple sensors need to be adjusted. After the vehicle has been running for a period of time, the mechanisms where these sensors are located Deformation, movement, damage, resulting in failure, making the door not closed tightly, not in place, requiring professional maintenance personnel to make regular adjustments
