Control Device and Method for Controlling Traveling Speed of a Vehicle

A control device and a method for controlling traveling speed of a vehicle for the purpose of maintaining a vehicle speed equal to or lower than a pre-set downhill speed (v.sub.dh-set). The method comprises simulating a vehicle speed profile for an upcoming road section if braking at a pre-identified power level (P1, P2, P3) would currently be requested, thereby obtaining a predicted maximum vehicle speed (v.sub.P1,max, v.sub.P2,max, v.sub.P3,max) and a predicted time until a vehicle speed equal to or within a pre-selected interval (I.sub.dh) of the pre-set downhill speed is reached. The method further comprises, if the predicted maximum vehicle speed is equal to or below the pre-set downhill speed (v.sub.dh-set) and the predicted time is below a preselected threshold time limit, requesting braking at the pre-identified power level or at an adjusted power level.

A braking control device includes: a control unit that is configured to control front-wheel braking power and rear-wheel braking power based on braking power distribution and requested braking power; a distribution setting unit that is configured to set the braking power distribution; and a slip judgment unit that is configured to judge whether or not the vehicle is in a rear-wheel-led slip state. If it is judged that the vehicle is in the rear-wheel-led slip state when the braking power distribution is first braking power distribution, the distribution setting unit executes a distribution shifting process of shifting the braking power distribution to second braking power distribution within a predetermined period. The second braking power distribution is such distribution that the rear-wheel braking power is reduced relative to that observed when the first braking power distribution is set as the braking power distribution.

VEHICLE CONTROL APPARATUS AND METHOD FOR CONTROLLING THE SAME

A vehicle control apparatus and a method for controlling the same are disclosed. The vehicle control apparatus includes an inputter, a determiner, and a controller. The inputter receives an automatic vehicle hold (AVH) switch operation signal from an AVH device, and receives a current vehicle movement value sensed by a sensing device and a current vehicle brake force value of a brake device that generates brake force in response to activation of the AVH device. The determiner determines whether the received AVH switch operation signal transitions from an ON state to an AVH entry state, determines whether vehicle movement occurs on the basis of the received current vehicle movement value during an AVH retention time in the AVH entry state, and determines that the current vehicle brake force value is in an abnormal state when vehicle movement occurs. The controller receives the current vehicle movement value and the current vehicle brake force value, and transmits a command for judgment to the determiner.
