Abstract

The invention belongs to the technical field of engines, and specifically relates to a double-ECU control device for a V type engine, and a control method for controlling the V type engine through thedouble-ECU control device. The double-ECU device comprises cam shaft signal plates, a first rotating speed sensor, a second rotating speed sensor, a first ECU controller and a second ECU controller,wherein the cam shaft signal plates are arranged on a cam shaft and can be rotated together with the cam shaft; the first rotating speed sensor and the second rotating speed sensor are arranged on theouter side surfaces of the cam shaft signal plates; the first rotating speed sensor can be electrically connected to the first ECU controller; and the second rotating speed sensor can be electricallyconnected to the second ECU controller. With the adoption of the double-ECU control device for the V type engine and the control method, the quantity of arranged cam shaft signal plates are decreased; the detecting accuracy is improved; and the manufacturing cost is decreased.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a dual-ECU control device for a V-type engine and a control method for using the dual-ECU control device to control the V-type engine. Background technique [0002] The V-shaped eight-cylinder engine is controlled by dual ECUs, and each ECU controls 4 cylinders. Since each ECU needs a camshaft speed signal, a total of 2 camshaft speed signals are required. In the prior art, two camshaft signal discs and two camshaft sensors are used for signal detection. [0003] Yet existing technology has following shortcoming: [0004] 1. Two camshaft signal discs are used, the accumulation of machining errors is large, the system control accuracy is poor, and the cost is high; [0005] 2. The two camshaft sensors are respectively arranged at both ends of the engine, and the connecting wire harness is separated and long; [0006] 3. Since the starter is close to the camshaft se...
