Vehicle control system

A vehicle control system comprising:

• an actuator;
• and
• an electronic control unit configured to
• recognize a vehicle speed of a host vehicle,
• recognize a surrounding environment of the host vehicle,
• determine, based on the vehicle speed of the host vehicle and the surrounding environment, whether the host vehicle and a preceding vehicle ahead of the host vehicle are stationary,
• determine, based on the surrounding environment, whether the preceding vehicle has started in a case where it is determined that the host vehicle and the preceding vehicle are stationary,
• determine, when it is determined that the host vehicle and the preceding vehicle are stationary, whether one of conditions is satisfied, the conditions including (i) a first condition for determining, based on the surrounding environment, that an adjacent vehicle has started, the adjacent vehicle being another vehicle stationary adjacent to the host vehicle in an adjacent lane adjacent to a traveling lane in which the host vehicle travels, (ii) a second condition for determining, based on the surrounding environment, that a first timing does not indicate a second timing, the first timing being a timing at which the preceding vehicle has started, the second timing being a timing at which a slipping-by vehicle has been lost, the slipping-by vehicle being a vehicle that slips by the host vehicle for moving ahead of the host vehicle, and (iii) a third condition for determining, based on the surrounding environment, that a second preceding vehicle has started, the second preceding vehicle being another vehicle stationary ahead of the preceding vehicle in the traveling lane, and
• start the host vehicle by using the actuator when at least one of the first condition, second condition, and third condition is satisfied.
