VEHICLE CONTROL APPARATUS, VEHICLE CONTROL SYSTEM, AND VEHICLE CONTROL METHOD
First Claim
1. A vehicle control apparatus of a vehicle, comprising:
- a first calculating unit that calculates a curve curvature radius of a road where the vehicle travels;
a second calculating unit that calculates a transverse direction acceleration in a direction intersecting with a traveling direction of the vehicle;
a setting unit that sets an allowable upper limit value of the transverse direction acceleration, according to the curve curvature radius; and
a control unit that performs a control to accelerate or decelerate the vehicle,wherein, in a case where the transverse direction acceleration is larger than the allowable upper limit value, the control unit performs control such that the vehicle accelerates.
