Vehicle running stability control apparatus
First Claim
1. A vehicle stability control apparatus comprising a vehicle running stability control device for controlling an automotive vehicle for stable running of the vehicle, and a braking device including a plurality of brakes for braking respective wheels of the vehicle, said vehicle running stability control device activating the braking device to provide turning stability control through a differential application of braking force to at least one of the wheels, said apparatus further comprising:
- a hazard detecting device for detecting a hazardous condition of the vehicle, the hazardous condition being determined when the turning stability control is insufficient to avoid an undesirable event due to a motion of the vehicle; and
an automatic brake application device operable to activate said braking device when said hazard detecting device to brake said vehicle has detected said hazardous condition of the vehicle at least during an operation of said vehicle running stability control device, the manner of activation of said braking device by said automatic brake application device being different from a manner of activation of said braking device by said turning stability control device.

11. A vehicle-collision preventing apparatus for preventing a collision of an automotive vehicle with an obstacle, said automotive vehicle having a running stability control device for effecting turning stability control of the vehicle, said vehicle-collision preventing apparatus comprising:
-
a braking device for applying a brake to the vehicle;
a running-path estimating device for estimating a running path of the vehicle;
an obstacle detecting device for detecting an obstacle existing in front of the vehicle and in said running path of the vehicle estimated by said running-path estimating device;
a vehicle speed detecting device for detecting a running speed of the vehicle;
a vehicle-collision determining device for determining, on the basis of said running speed detected by said vehicle speed detecting device, whether there is a risk of a collision of the vehicle with said obstacle detected by said obstacle detecting device on an assumption that the vehicle is braked at a predetermined reference deceleration value;
an automatic brake application device operable to activate said braking device to brake said vehicle at a deceleration value whose absolute value is larger than that of said reference deceleration value, when said vehicle-collision determining device has determined there is said risk of the collision of the vehicle with said obstacle; and
a running stability control terminating device for terminating a turning stability control of the vehicle by said braking device through a differential application of braking force to at least one of wheels of the vehicle when said braking device is activated by said automatic brake application device during said turning stability control. - View Dependent Claims (12)

13. A vehicle-deviation preventing apparatus for preventing a deviation of an operator-controlled automotive vehicle from a nominal running path of the vehicle, said automotive vehicle having a running stability control device for effecting turning stability control of the vehicle, said vehicle-deviation preventing apparatus comprising:
-
a braking device for applying a brake to the vehicle;
a running-path detecting device for detecting a nominal running path of the vehicle;
a vehicle-deviation determining device for determining whether there is a risk of a deviation of the vehicle from the detected nominal running path;
an automatic brake application vehicle operable to activate said braking device to brake said vehicle when said vehicle-deviation determining device has determined that there is a risk of the vehicle deviation from said detected nominal running path; and
running stability control terminating device for terminating a turning stability control of the vehicle by said braking device through a differential application of braking force to at least one of wheels of the vehicle, when said braking device is activated by said automatic brake application device during said turning stability control. - View Dependent Claims (14, 15, 16)
an alarm indicator device operable when said vehicle-deviation determining device has determined that there is said risk of the deviation of the vehicle, to warn an operator of the vehicle that there is said risk;
an operator-controlled member; and
an automatic-brake-application inhibiting device for inhibiting an operation of said automatic brake application device when said operator-controlled member is operated, and wherein said automatic brake application device activates said braking device when a predetermined time has passed without an operation of said operator-controlled member after said alarm indicator device is operated.
