1. A vehicle control system, comprising:
a first power supply;
a plurality of first sensors connected to the first power supply;
a first actuator connected to the first power supply;
a first calculation unit connected to the first power supply;
a second power supply:
a plurality of second sensors connected to the second power supply;
a second actuator connected to the second power supply:
a second calculation unit connected to the second power supply and communicably connected to the first calculation unit; and,
a vehicle control calculation unit connected to the first power supply and configured to control the first actuator, wherein:
the first calculation unit integrates external environment information acquired by the plurality of first sensors and external environment information acquired by plurality of second sensors, estimates a vehicle position using the integrated external environment information, creates an action plan using the estimated vehicle position, and transmits the created action plan to the vehicle control calculation unit, the vehicle control calculation unit to output control signals to the first actuator to implement the action plan,
the second calculation unit executes a calculation for driving assistance using the external environment information acquired by the plurality of second sensors, and outputs control signals to control the second actuator to operate a vehicle using a result of the calculation,
the first calculation unit executes calculation processing for autonomous driving, and the second calculation unit executes calculation processing to assist the calculation for the autonomous driving by the first calculation unit responsive to the vehicle operating in an autonomous driving mode of driving automation level 3 or higher,
the second calculation unit executes a calculation for driving assistance, and the first calculation unit verifies a result of the calculation for driving assistance executed by the second calculation unit responsive to the vehicle operating with driving assistance of driving automation level 2 or lower,
the second calculation unit executes calculation processing of degenerated vehicle control for driving assistance responsive to the first calculation unit failing, and
the first calculation unit executes calculation processing of degenerated vehicle control using external information acquired by the plurality of first sensors responsive to the second calculation unit failing.
