Embodiment Construction

[0027] Such as figure 1 As shown, a method for starting control of a micro-hybrid system for an unmanned aerial vehicle, the specific steps are:

[0028] ECU obtains signals from crankshaft position sensor and camshaft position sensor; figure 2 As shown, the obtained crankshaft and camshaft position sensor signals are pulse signals, wherein the crankshaft position signal has a wider timing signal, and the camshaft position signal has a timing signal generated simultaneously with the crankshaft position signal (top dead center In addition to the signal), a top dead center signal will be generated every 180°.

[0029] The motor driving the hybrid system reverses the preset angle;

[0030] Drive the motor of the hybrid system to rotate the mechanical angle of 150° to 180° according to the opposite direction of rotation during normal operation. The brushless motor with Hall position sensor driven by the six-step commutation method is the preferred example. The coding array of ...

Abstract

The invention provides a starting control method of a micro hybrid power system for an unmanned aerial vehicle. The method comprises the following steps that an ECU acquires signals of a crankshaft position sensor and a camshaft position sensor; a motor of a hybrid power system is driven to reverse for a preset angle; a position of a piston component is determined according to a position signal and a crankshaft motion state produced in the reverse process, and the motor is driven to reverse to a determined position; the motor is normally driven to start, the hybrid power system is started, andthe control process is finished. Through the starting control method provided by the invention, the problems of short acceleration stroke of piston component and difficult starting in the hybrid power system are solved.

Description

technical field [0001] The invention belongs to the technical field of start-up control of a hybrid system, and in particular relates to a start-up control method for a micro-hybrid system for an unmanned aerial vehicle. Background technique [0002] For the evaluation of the overall performance of the hybrid system, its starting success rate is one of the evaluation conditions. If the starting resistance is too large, the piston assembly cannot cross the top dead center when starting. In addition to starting failure, it may also cause reverse or recoil phenomenon. For some equipment or occasions where the main shaft is prohibited from reversing, there is an immeasurable effect. hazards and hazards. [0003] The micro drone hybrid system can effectively solve the problems of short battery life and weak load capacity of electric drones. The micro-hybrid system for drones is mainly composed of a small-displacement two-stroke piston engine and a generator. Because the power ...
