1. A computer-implemented method for controlling vehicle sensor data acquisition using a vehicular communication network, comprising:

  • establishing an operable connection for computer communication between a first vehicle and a second vehicle using the vehicular communication network;

    receiving a global time signal at the first vehicle and at the second vehicle, wherein a processor of the first vehicle synchronizes a local clock signal of the first vehicle with the global time signal, and a processor of the second vehicle synchronizes a local clock signal of the second vehicle with the global time signal;

    determining a capture interval for a sensor data acquisition process time that maximizes a total number of data frames that can be captured by a sensor of the first vehicle and by a sensor of the second vehicle that is based on a number of vehicles within a predetermined distance from the first vehicle;

    transmitting a first sensor trigger pulse according to the capture interval to the sensor of the first vehicle thereby triggering acquisition of sensor data from the sensor of the first vehicle, wherein the first vehicle transmits the sensor data from the sensor of the first vehicle to the second vehicle; and

    transmitting a second sensor trigger pulse according to the capture interval to the sensor of the second vehicle thereby triggering acquisition of sensor data from the sensor of the second vehicle, wherein the second sensor trigger pulse is offset from the first sensor trigger pulse by the capture interval, and wherein the second vehicle transmits the sensor data from the sensor of the second vehicle to the first vehicle.
