Abstract

The invention relates to the technical field of engines, and particularly discloses a redundant engine rotating speed control device which comprises an electric control unit, a first crankshaft rotating speed sensor, a second crankshaft rotating speed sensor, a cam rotating speed sensor, a crankshaft signal panel and a cam signal panel; the first crankshaft rotating speed sensor and the second crankshaft rotating speed sensor are used for collecting rotating speed signals of the crankshaft signal panel; the cam rotating speed sensor is used for collecting rotating speed signals and phase signals of the cam signal panel; and the electronic control unit is used for carrying out corresponding engine rotating speed and phase calculation according to the signal states of the first crankshaft rotating speed sensor, the second crankshaft rotating speed sensor and the cam rotating speed sensor, outputting the available engine rotating speed and phase, and determining the engine rotating speed and phase according to the available engine rotating speed and phase so as to carry out fuel injection control. The invention further discloses a redundant engine rotating speed control method. The redundant engine rotating speed control device is simple, reliable and low in cost.

Description

Technical field [0001] The present invention relates to the field of engine technology, and more particularly to a redundant engine speed control device and a redundant engine speed control method. Background technique [0002] With the upgrade of emission regulations, the improvement of product safety reliability requires higher requirements for engine use of automotive, ships, etc., and redundancy control is one of them. The purpose of redundant control is that when the engine component or part of the system fails, there is still a speed control capability, and maintains the engine to continue to operate, and ensure safe security. [0003] At present, the engine redundancy control method proposed in the engine is, mainly redundant for fuel (mechanical) systems, electronically controlled systems, including ECU, actuator, sensor, etc., adds one by another. Indurate fuel systems or electronically controlled systems, and even complete systems, greatly increase design cost, cost and...
