Description

Technical Field

[0001] The invention relates to an intelligent control system and method for a telescopic automobile side pedal, belonging to the technical field of automobile side pedal design. Background Art

[0002] The car side pedal is an accessory installed on the side of the car. Its function can assist the driver and passengers in getting on and off the car, improving convenience and comfort.

[0003] Most of the existing side pedals are fixedly installed. When the vehicle is driving or parked normally, the entire side pedals extending to the left and right often cause defects such as occupying space or increasing wind resistance. When the vehicle is parked by the side of the road, the entire extended pedals are often prone to collide with the curb or other obstacles on the roadside, causing damage to the pedals. To solve the above problems, a more commonly used method is to add an integral telescopic pedal to the side of the vehicle. However, when the door is closed, the side pedal remains hidden under the vehicle body, which will result in it being unable to protect the side skirts of the vehicle body in the event of a small friction collision. In addition, this integral telescopic side pedal also lacks anti-collision function during the telescopic process. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent control system and method for a retractable automobile side pedal, which on the one hand solves the defects of the automobile side pedal occupying space, and on the other hand enables the integrated retractable side pedal to have an anti-collision function during the retraction process, thereby reducing safety hazards.

[0005] The present invention discloses an intelligent control system for a retractable automobile side pedal, comprising a controller, a CAN bus interface, a radar probe, and a pressure sensor. The controller is connected to the CAN bus interface and the radar probe, and the sensor is connected to the CAN bus interface. The radar probe and the pressure sensor are both installed on the side pedal. The radar probe is used to detect whether there is an obstacle in the retractable area of ​​the side pedal, and the pressure sensor is used to detect a pressure signal on the side pedal and send the pressure signal to the controller through the CAN bus interface.

[0006] Furthermore, the pressure sensor includes a left pressure sensor and a right pressure sensor, and the radar probe includes a left radar probe and a right radar probe, which are respectively installed on the corresponding left side pedal and right side pedal.

[0007] Furthermore, the system also includes a left-side driving module and a left-side electric push rod which are sequentially connected to the controller, and the left-side electric push rod is used to push the left side pedal to extend or retract.

[0008] Furthermore, the system also includes a right-side drive module and a right-side electric push rod which are sequentially connected to the controller, and the right-side electric push rod is used to push the right side pedal to extend or retract.

[0009] Furthermore, the radar probe is an ultrasonic sensor.

[0010] On the other hand, the present invention also provides a method for intelligently controlling a retractable automobile side pedal according to the above system, the method specifically comprising:

[0011] When the vehicle is unlocked, the pressure signal of the pressure sensor on the side pedal is received through the CAN bus interface;

[0012] Then the radar probe on the side pedal on the corresponding side is controlled to detect whether there is an obstacle in the extended area of ​​the pedal. If there is an obstacle, an alarm is issued; if there is no obstacle, the pedal is extended backward.

[0013] Furthermore, in the method, the pedal is extended backward by the controller controlling the electric push rod through the drive module on the corresponding side.

[0014] Furthermore, in the method, when the controller does not receive a pressure signal from the pressure sensor on the side pedal through the CAN bus interface, the side pedal remains in a retracted state; when the controller receives a pressure signal from the pressure sensor on the side pedal through the CAN bus interface, the controller controls the drive module to cause the electric push rod to push the side pedal to extend, and the side pedal remains in an extended state.

[0015] Compared with the prior art, the telescopic vehicle side pedal intelligent control system and method of the present invention has the following advantages:

[0016] (1) The intelligent control circuit of the present invention is used to control the retractable side pedal of the automobile and read the pressure signal on the side pedal in real time;

[0017] (2) The intelligent control circuit of the present invention controls the telescopic pedal on the corresponding side based on the pressure signal from the side pedal to achieve telescopic movement, and can realize automatic telescopic control of the pedal without adding additional operations, which is more convenient to use;

[0018] (3) The intelligent control circuit of the present invention detects obstacles in the monitoring area through the radar probe on the side pedal, thereby improving the safety of the side pedal extension and retraction.

[0019] (4) In the intelligent control circuit of the present invention, the left and right radar probes are composed of ultrasonic sensors. When there is an obstacle in the detection area, the corresponding radar probe will issue an alarm to improve safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figure 1 As shown, an intelligent control system for a retractable automobile side pedal is provided. A pressure sensor is integrated inside the retractable automobile side pedal, and an electric push rod is used to drive the side pedal to retract or extend.

[0026] A controller is provided in the control system, and the controller receives a pressure signal from a pressure sensor on a side pedal through a CAN bus interface. The controller is also connected to left and right drive modules. The left drive module is connected to an electric push rod for telescopic control of a left pedal of the automobile, and the right drive module is connected to an electric push rod for telescopic control of a right pedal of the automobile. The controller is also connected to left and right radar probes. A left radar probe 3 is provided on the left side pedal and is used to detect whether there is an obstacle in the telescopic area of ​​the left pedal. A right radar probe 2 is provided on the right side pedal and is used to detect whether there is an obstacle in the telescopic area of ​​the right pedal. When there is an obstacle in the detection area, the radar probe will issue an alarm prompt, and the side pedal will not extend outward. If no obstacle is detected, no alarm will be issued, and the electric push rod will be controlled to push the side pedal outward, so as to prevent the side pedal from being suddenly extended and damaged by collision.

[0027] like Figure 2-Figure 3 As shown, in order to realize the extension and retraction of the side pedal, when the controller does not receive the pressure signal of the pressure sensor on the side pedal through the CAN bus interface, the side pedal is maintained in the retracted state 1; when the pressure signal of the pressure sensor on the side pedal is received through the CAN bus interface, the controller controls the drive module to make the electric push rod push the side pedal to extend, and maintains the side pedal in the extended state 4.

[0028] like Figure 4As shown, in order to realize obstacle detection, the left radar probe 3 and the right radar probe 2 use ultrasonic sensors, and their detection areas correspond to the extension area of ​​the side pedal. When the controller receives the pressure signal of the pressure sensor on the side pedal through the CAN bus interface, the left radar probe 3 and the right radar probe 2 emit ultrasonic waves to detect their detection areas. If there is an obstacle in the detection area, an alarm is issued and fed back to the controller to keep the side pedal in the retracted state 1. If there is no obstacle in the detection area, the controller issues a command to the drive module to drive the electric push rod to push the side pedal to extend.

[0029] The embodiments described above are merely descriptions of preferred implementation modes of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
