Abstract:
1. A vehicle control system comprising: an actuator control ECU, connected to an intra-vehicle communication network, for controlling an actuator that operates in synchronism with a crankshaft angle of a vehicle engine; a sensor-ECU, connected to the intra-vehicle communication network to which the actuator control ECU is connected, for receiving a crankshaft signal and a camshaft signal of the vehicle engine; and a means for determining timing of an event with respect to crankshaft angle, wherein the sensor ECU includes crankshaft angle calculating means for calculating a crankshaft angle on the basis of the received camshaft signal and crankshaft signal and crankshaft angle outputting means for outputting the crankshaft angle calculated by the crankshaft angle calculating means to the means for determining timing via the intra-vehicle communication network, wherein the means for determining timing is provided in one of ECUs that are connected to the intra-vehicle communication network and determines operation timing of the actuator on the basis of the received crankshaft angle, and wherein the actuator control ECU includes timing control means for controlling the actuator on the basis of the timing determined by the means for determining timing.
