Control apparatus of vehicle

A control apparatus of a vehicle, comprising:

• an inter-vehicle distance detection device that detects an inter-vehicle distance between an own vehicle and a communicating preceding vehicle;
• a wireless communication device that acquires communicating preceding vehicle information including at least one of requested acceleration information on a requested acceleration of the communicating preceding vehicle and actual acceleration information on an actual acceleration of the communicating preceding vehicle from the communicating preceding vehicle through a wireless communication;
• and
• an acceleration control device that controls an acceleration of the own vehicle such that the acceleration of the own vehicle corresponds to a requested acceleration of the own vehicle,
• the acceleration control device including:
• first calculation means for calculating a feedback requested acceleration which is an acceleration requested by the own vehicle to maintain the inter-vehicle distance at a target inter-vehicle distance;
• second calculation means for calculating a feedforward requested acceleration which is an acceleration requested by the own vehicle to cause the own vehicle to travel following the communicating preceding vehicle on the basis of at least one of the requested acceleration information and the actual acceleration information;
• and
• third calculation means for calculating a requested acceleration of the own vehicle on the basis of the feedback requested acceleration and the feedforward requested acceleration,
• the acceleration control device being configured to execute a following travel control that causes the own vehicle to travel following the communicating preceding vehicle by controlling the acceleration of the own vehicle such that the acceleration of the own vehicle corresponds to the requested acceleration of the own vehicle calculated by the third calculation means,
• wherein the third calculation means is configured to set the feedforward requested acceleration to zero when the communicating preceding vehicle information includes information indicating that a vehicle travel stabilization control is executed to control a friction braking force applied to at least one of vehicle wheels of the communicating preceding vehicle from a friction braking device of the communicating preceding vehicle to stabilize a traveling of the communicating preceding vehicle, and indicating that the feedforward requested acceleration is larger than zero.
