Description
Technical Field
The invention belongs to the technical field of automobile step control, and particularly relates to a control method for an automobile integrated electric step control function and an automobile body controller.
Background
At present, most automobiles in the market have higher ground clearance for ensuring the passing property of the automobile, drivers and passengers have poor convenience for getting on and off the automobile, and certain potential safety hazards exist under partial emergency situations. Especially in some subdivided vehicle type fields (such as commercial passenger cars, school buses and the like), the device has higher requirements on the convenience and safety of getting on and off the bus by drivers and passengers, and is a focus of attention of people. The existing main technical scheme is that a telescopic stepping device is designed below a vehicle door, so that ground clearance is reduced, and the vehicle evacuation device is beneficial to rapid, comfortable and safe evacuation of drivers and passengers.
The general scheme of getting on the bus and stepping the existing vehicle is similar to that described in CN 102910117A, school bus safety door lower expansion stepping controller and its control method, and the independent expansion stepping controller is adopted, including five parts of safety door switch detection circuit, door open indicator lamp control circuit, expansion stepping opening electromagnetic valve control circuit, expansion stepping closing electromagnetic valve control circuit, control single chip microcomputer, etc. The safety door switch detection circuit, the safety door opening indicator lamp control circuit, the telescopic step opening electromagnetic valve control circuit and the telescopic step closing electromagnetic valve control circuit are respectively connected with the single chip microcomputer.
The hardware block diagram is shown in fig. 1, and the specific control method is as follows:
1) the safety door switch detection circuit detects a vehicle door switch signal, when a vehicle door is opened, a vehicle door switch is switched on, and a pin RA0 of the single chip microcomputer receives a low level signal; the RC0 pin outputs high level, the safety door opening indicating lamp control circuit works to drive the door opening indicating lamp to be on; a high level lasting for one second is immediately output by an RC1 pin, the electromagnetic valve control circuit is opened by the telescopic step to work, and the telescopic step is opened and kept; and a pin RC2 outputs low level, and the control circuit of the solenoid valve for closing the telescopic step does not work.
2) The safety door switch detection circuit detects a vehicle door switch signal, when a vehicle door is opened, the vehicle door switch is switched off, and a pin RA0 of the single chip microcomputer receives a high-level signal; the RC0 pin outputs low level, the safety door opening indicating lamp control circuit does not work, and the door opening indicating lamp is driven to be turned off; a pin RC1 outputs low level, and the control circuit of the solenoid valve is opened by the telescopic step to stop working; and a pin RC2 outputs a high level, the telescopic step closes the electromagnetic valve control circuit to work, and the step retracts.
The main thinking of the prior art is to adopt an independent controller, and a car door switch is used as a controller input signal, so that the following can be realized:
1) the opening of the telescopic step moves along with the opening of the safety door, so that precious time is saved for escape.
2) The opening/closing of the telescopic steps is automatically controlled by the telescopic step controller according to the state of the safety door, so that potential safety hazards caused by manual misoperation are avoided.
3) When the automobile is normally driven, the safety door is in a closed state, the telescopic stepping controller controls the telescopic stepping to be in a withdrawing state, and the safety of driving is effectively guaranteed.
However, the prior art still has the following problems and disadvantages:
1) and an independent controller (an alarm system also adopts an independent buzzer for alarming) is adopted, so that the manufacturing cost is high.
2) The reliability of the controller is controlled based on the door state, the requirement on the reliability of the door state is high, and once a door switch signal is unstable due to factors such as door installation and adjustment errors or problems caused by matching of doors after a period of use, and the like, serious consequences are brought; especially, when the automobile is running, if the door signal distortion is in the opening state, the step will be extended out, and the door signal distortion will scratch the periphery of the automobile during running, so that a major safety problem will occur.
3) The controller does not have the capacity of online program diagnosis and null update, when a program fault occurs or a control algorithm is optimized, the controller needs to be removed and then updated or parts need to be replaced, and the controller is poor in maintenance convenience and high in cost.
4) The controller has single function and poor expansion performance, and does not have iterative upgrade capability.
