摘要： PROBLEM TO BE SOLVED: To provide a vehicle controller and a vehicle control method, capable of suppressing the propagation of vehicle speed fluctuation.
SOLUTION: In the vehicle controller and the vehicle control method, when an inter-vehicle distance between a self-vehicle 11 and a preceding vehicle 12 is within a prescribed range when performing the deceleration control of a self-vehicle 11 to maximize a traffic flow rate, the deceleration control of the self-vehicle to an inter-vehicle distance and a vehicle speed to maximize the traffic flow rate is performed, and when the inter-vehicle distance between the self-vehicle 11 and the preceding vehicle 12 is not within the prescribed range, the deceleration control of the self-vehicle only to the speed to maximize the traffic flow rate is performed. Thereby, even when a situation, in which it is not possible to secure or maintain the inter-vehicle distance to maximize the traffic flow rate until a sag part is reached, is generated, the deceleration control of the self-vehicle 11 so as to be the vehicle speed to at least maximize the traffic flow rate is performed. Therefore, the propagation of vehicle speed fluctuation is effectively suppressed, and then the suppression of sag traffic jam is achieved.
