Technical Field

The invention belongs to the technical field of electronic injection motorcycles, and particularly relates to an electronic injection motorcycle ECU atmospheric pressure setting method.

Background

For an electronic fuel injection ECU based on a 'rotating speed-opening degree' control model algorithm, in order to adapt to a plateau use environment, the fuel quantity needs to be subjected to atmospheric pressure correction (namely, the fuel quantity is subjected to coefficient correction according to local atmospheric pressure). Since such an electronic fuel injection system is not equipped with a related sensor for detecting the atmospheric pressure, the ECU cannot acquire data related to the local atmospheric pressure through the atmospheric pressure sensor.

In order to obtain the local default atmospheric pressure, some conventional ECUs use a setting tool based on communication methods such as a CAN line and a K line to communicate with the ECU, and directly set the default atmospheric pressure value of the ECU. However, for the requirements of low cost and high quality commonly existing in the motorcycle industry, the professional level of after-sale maintenance personnel is low, and the requirements of convenience of after-sale maintenance and the like are simultaneously required, the solution obviously has the defects of high application cost and the need of additionally carrying and setting tools.

The technical scheme adopted by the invention for solving the technical problems is as follows:

an electronic fuel injection motorcycle ECU atmospheric pressure setting method comprises the following steps:

s1, entering a setting mode;

presetting an identification program when the ECU enters a setting mode, wherein the identification program comprises the state identification of the ECU on the opening degree of an accelerator and the state identification of the ECU on an ignition switch; setting the state value of the accelerator opening degree as A, setting the state value of the ignition switch as C, and when the state value A is met and the reaching times of the state value C are N₁Then, the ECU enters a setting mode;

s2, setting an atmospheric pressure value;

setting the state value of the accelerator opening degree as B, setting the state value of the ignition switch as D, and identifying the reaching times N of the state value D by the ECU when the state value B is met₂An atmospheric pressure value corresponding to the number of times of reaching the state value D is preset in the ECU, and the ECU identifies the N₂And writing the corresponding atmospheric pressure value into a Flash data storage position to complete the setting of the atmospheric pressure value.

Further, in step S1, the ECU is electrically connected to at least one indicator light on a motorcycle dial, and when the ECU enters a set mode, the ECU issues an instruction to make the indicator light flash, where the number of times of flashing is N₃。

Further, in step S2, the ECU is electrically connected to at least one indicator light on the motorcycle dial, and when the ECU completes setting of the atmospheric pressure value, the ECU issues an instruction and causes the indicator light to flash, where the number of times of flashing is N₄。

Further, the state value C of the ignition switch is that the ignition switch is in an on state, and N is₁The number of times the ignition switch is in the on state in continuous on and off.

Further, the state value B of the accelerator opening degree is controlled through an accelerator handle, and when the state value of the accelerator opening degree reaches B, the rotation amplitude of the accelerator handle is larger than or equal to 80%.

Further, the state value D of the ignition switch is that the ignition switch is in an on state, and N is₂The number of times the ignition switch is in the on state in continuous on and off.
