Abstract:
A vehicle control device generates a speed pattern alternately repeating an acceleration travel pattern having a section accelerating a host vehicle and an inertia travel pattern having a section with an acceleration driving force of zero and a deceleration braking force of zero with respect to the wheels of the host vehicle. The speed pattern is generated by reducing speed of the host vehicle in front of any one position of an intersection of the road on which the host vehicle travels and an exit leading to the road. The intersection and the exit may encounter another vehicle, and may include a traffic flow of other vehicles on a road with a host vehicle. Matching a proved speed by reducing vehicle speed of a speed pattern with a position of an intersection or an exit, the host vehicle may cooperate with traffic flow to improve fuel efficiency.
Abstract:
A steering control device for a vehicle includes a steering characteristic setting unit setting the range of a steering manipulation angle corresponding to a tire angle in a predetermined range (near an induction target tire angle for guiding to a target locus), which is determined on the basis of the target locus upon vehicle traveling, to be wider than the range of a steering manipulation angle corresponding to a tire angle outside of the predetermined range. A reduction gear ratio of a steering mechanism in the predetermined range increases.
Abstract:
Disclosed is a travel control device for easily achieving a target acceleration/deceleration even by a manual operation of a driver. A travel control device for controlling at least acceleration/deceleration of a vehicle includes acceleration/deceleration characteristic setting means for setting the range of an accelerator operation amount or a brake operation amount corresponding to an induced target acceleration/deceleration greater than the range of an accelerator operation amount or a brake operation amount corresponding to an acceleration/deceleration other than the induced target acceleration/deceleration. The acceleration/deceleration characteristic setting means generates a map GM1 in which the range of the accelerator operation amount or the brake operation amount corresponding to the acceleration/deceleration for achieving the induced target acceleration/deceleration is set greater than a basic map BM1, which defines the relationship between the accelerator operation amount and the acceleration/deceleration corresponding to the accelerator operation amount and the relationship between the brake operation amount and the acceleration/deceleration corresponding to the brake operation amount.

Abstract:
Disclosed are a vehicle control device and a vehicle control method capable of performing appropriate traveling control while exhibiting the capability of a control system. Feedback control is performed according to a traveling target set in advance. At the time of the feedback control, when a vehicle traveling trace is deviated, when a tire friction circle is exceeded, or when a vehicle acceleration or a jerk exceeds a set value, if a control deviation exceeds a set value, a traveling target is regenerated. This enables appropriate traveling control while sufficiently exhibiting the capability of the control system until the control deviation exceeds the set value. When the control deviation exceeds the set value, a traveling target is regenerated, such that traveling control appropriate for the traveling environment can be performed.

A redundancy computing part 22 computes a redundancy between respective detectable regions D of perimeter monitoring sensors 10 mounted in a plurality of vehicles, while a driving schedule creating part 26 creates such a driving schedule as to lower the redundancy between detectable regions D computed by the redundancy computing part 22, thus making it possible to create a driving schedule which reduces parts where the respective detectable regions D of the perimeter monitoring sensors 10 of the vehicles overlap, thereby increasing areas where obstacles can directly be detected by the perimeter monitoring sensors 10 of the vehicles.
