  • Publication number: 20120271499
    Abstract: In a vehicle travel controlling apparatus including an automatic travel controlling ECU that controls a vehicle in a predetermined travel state by cooperation control of a vehicle driving amount and a vehicle braking amount, the automatic travel controlling ECU is provided with an automatic travel termination controlling unit. The automatic travel termination controlling unit obtains a brake fluid pressure during the cooperation control according to the vehicle driving amount during the cooperation control and a gradient of a road surface on which a vehicle is travelling. When the brake fluid pressure corresponding to a braking operation of a driver is more than the brake fluid pressure during the cooperation control, the automatic travel termination controlling unit terminates the cooperation control to switch operation to a braking operation according to the brake fluid pressure corresponding to the braking operation.

  • Patent number: 7980346
    Abstract: An electronic control device reduces, after a time at which constant speed traveling control is terminated (specific control termination time) not by an accelerating operation or braking operation but by, for example, an operation of a control switch, the vehicle driving force to a force corresponding to the amount of accelerating operation at the specific control termination time.

  • Patent number: 7894971
    Abstract: A vehicle control apparatus is used to control a driving force to be given to a vehicle. A driving force calculating device calculates the driving force to be given to the vehicle, on the basis of a deviation between a vehicle speed of the vehicle and a target speed. A driving force correcting device performs correction of increasing the driving force calculated by the driving force calculating device, when the vehicle speed reduces to a predetermined value or less. Specifically, the driving force correcting device performs the correction of increasing the driving force, when the vehicle speed reduces to the predetermined value or less as the vehicle comes in contact with an obstacle, such as a bump. By this, it is possible to reduce a stop time length of the vehicle due to the contact with the obstacle, to thereby quickly make the vehicle run over the obstacle.

  • Publication number: 20100100295
    Abstract: If a condition for finishing speed limit control is satisfied, a gradient of a slope of the road is estimated based on a steady component of the longitudinal acceleration of the vehicle, and a correction factor is computed based on the slope gradient of the road, while a target acceleration of the vehicle is computed based on the vehicle speed. Then, a target vehicle speed is computed by adding the target vehicle speed of the last cycle to the product of the correction factor, target acceleration and the cycle time of the control, and the braking or driving force of each wheel is controlled so that the vehicle speed becomes equal to the target vehicle speed. In this manner, a passenger of the vehicle is prevented from feeling uncomfortable about the speed increase after the completion of the vehicle speed limit control.
