Problems solved by technology

[0003] But when this control mode is applied to the motorcycle to control the idle air volume, it can only control the maximum amount of air volume and the two limit states of fully closed to zero, so that the air volume changes greatly, which will lead to engine failure. Speed ​​drop from high to low
Especially in plateau areas, it will cause the engine speed to be very unstable, or even stalled

Embodiment 1

[0045] When the vehicle is driving in a plain area, the atmospheric pressure sensed by the first sensor 2 is 101.3kPa, and the engine temperature sensed by the second sensor 3 is 20 degrees. The engine temperature value matches the operating characteristic data of the electromagnetic switching valve from the database module 11, that is, the operating characteristic data under the above-mentioned conditions is: the duty ratio (DutyN) is 50%, and the number of times of implementation (Mx) is 100 times; then The single cycle time T0 of the electromagnetic switch valve is set by the parameter setting module 13 to be 20ms, wherein T0 and DutyN satisfy the following formula: DutyN=(tN / T0)*100%, where tN is the single cycle time of the electromagnetic switch valve Second opening time; the main control chip 10 controls the operation of the electromagnetic switch valve for 2s according to "DutyN is 50%, Mx is 100 times, T0 is 20ms", and after the 2s work is over, the main control chip 1...

Embodiment 2

[0049] When the vehicle is driving at an altitude of 2,500 meters on a plateau, the atmospheric pressure sensed by the first sensor 2 is 75kPa, and the engine temperature sensed by the second sensor 3 is 10 degrees. value and the engine temperature value from the database module 11 to match the operating characteristic data of the electromagnetic switch valve, that is, the operating characteristic data under the above-mentioned conditions is: the duty ratio (DutyN) is 75%, and the number of times of implementation (Mx) is 200 times ; Then set the single cycle time T0 of the electromagnetic switch valve by the parameter setting module 13 to be 20ms, wherein T0 and DutyN satisfy the following formula: DutyN=(tN / T0)*100%, where tN is an electromagnetic switch Valve single opening time; the main control chip 10 controls the operation of the electromagnetic switch valve for 4s according to "DutyN is 75%, Mx is 200 times, and T0 is 20ms", and after the 4s work ends, the main control ...

Abstract

The invention discloses a control device of an electromagnetic switch valve and a control method thereof. The control device comprises a controller, a first sensor for sensing vehicle running environment condition information and a second sensor for sensing engine working state information, wherein the controller is integrated with a main control chip and a database module, and the database moduleis used for storing running characteristic data sets of the electromagnetic switch valve under different vehicle running environment conditions and different engine working state conditions; and thefirst sensor and the second sensor are both electrically connected with the main control chip, and the main control chip matches the operation characteristic data of the electromagnetic switch valve from the database module according to the vehicle running environment condition and engine working state information received by the main control chip, and correspondingly controls the electromagneticswitch valve to work according to the operation characteristic data. The control device is simple and reasonable in structure, and easy to control, graded control on the air intake of the electromagnetic switch valve can be achieved, and starting performance and idling stability performance of a vehicle are ensured when the vehicle is used in plain areas and plateau areas.

Description

technical field [0001] The invention relates to the technical field of electromagnetic switch valve control, and specifically provides a control device and a control method for an electromagnetic switch valve. Background technique [0002] Generally, the control mode of the electromagnetic switch valve on a motorcycle has only two states of open and closed, which can realize a relatively simple on-off function. [0003] But when this control mode is applied to the motorcycle to control the idle air volume, it can only control the maximum amount of air volume and the two limit states of fully closed to zero, so that the air volume changes greatly, which will lead to engine failure. The drop of speed from high to low. Especially in plateau areas, it will cause the engine speed to be very unstable, or even stalled. Therefore, there is a need for a control method that can control the idling air volume to decrease step by step. [0004] In view of this, the present invention i...
