<p>A travel controlling apparatus of a vehicle (11) includes a slip ratio detecting unit (31) that obtains a slip ratio of front wheels (12FL, 12FR) and rear wheels (12RL, 12RR) depending on a travel state of the vehicle (11), a friction coefficient detecting unit (32) that obtains a friction coefficient of the front wheels (12FL, 12FR) and the rear wheels (12RL, 12RR) depending on the travel state of the vehicle (11), a slip ratio stable region setting unit (33) that sets a slip ratio stable region in which the friction coefficient becomes a predetermined value or more depending on the travel state of the vehicle (11), a braking/driving force controlling unit (34) that controls a braking/driving force in the slip ratio stable region, and a slip ratio stable region changing unit (35) that changes an upper limit value and a lower limit value in the slip ratio stable region depending on a variation of the friction coefficient when the slip ratio increases and when the slip ratio decreases.</p> |
