Abstract: The movement of the vehicle is controlled so that the travel time does not become long while reducing the fuel consumption of the vehicle. A vehicle control device 1 that automatically controls a speed of a vehicle is configured to include an acceleration/deceleration pattern setting unit 22 that sets a plurality of acceleration/deceleration patterns including acceleration and deceleration in a traveling scheduled zone and sets the speed to be the same in a region between an acceleration region and a deceleration region in each acceleration/deceleration pattern based on traveling history in a traveling scheduled zone.

Abstract: When acceleration control is interrupted due to a lane change or the like, the engine speed is controlled from a high rotation speed to a low rotation speed, a variation in engine speed increases, and poor driver's driving performance is brought about. Furthermore, suppression of acceleration when there is a lane change possibility may rather cause the lane change and the driver feels discomfort. The vehicle control unit according to the present invention includes a target engine speed calculation unit which corrects a target engine speed to be reduced relative to a predetermined target engine speed when the acceleration/deceleration possibility determination unit determines that there is a deceleration possibility during acceleration to a target vehicle speed in automatic acceleration/deceleration control, and an engine control unit which controls an engine to have a target engine speed corrected by the target engine speed calculation unit.

Abstract: In order to prevent cell batteries from reaching a regeneration inhibiting voltage in an initial period of regeneration braking and to ensure that a large amount of regeneration can be secured even if characteristics of cell batteries are varied, when a vehicle braking request is received (S2-2), a first limit of regeneration power (S2-8) for which the amount of regeneration is relatively small is performed, and while regeneration control is being performed, information about the cell batteries such as voltage across terminals is acquired from a battery monitoring device to identify a cell battery of which the voltage across terminals becomes the highest among the multiple cell batteries. After the determination is completed (S2-5), the process proceeds to a second regeneration control (S2-9). In the second regeneration control, regeneration is performed by using an upper limit amount of regeneration with which an identified worst cell battery would not reach the regeneration inhibiting voltage as a limiting value.

Abstract: A vehicle control device includes a determination unit, a speed control unit, and a recommended speed acquisition unit. The recommended speed acquisition unit acquires a first recommended speed, being a new recommended speed related to a first section. The determination unit determines a magnitude relationship between the first recommended speed and the first recommended speed. The speed control unit controls the speed of the vehicle to be maintained at a speed of the first recommended speed in the first section when the determination unit determines that the first recommended speed is less than the first recommended speed.
