Control apparatus for ensuring safety of a vehicle run
First Claim
1. A control apparatus for ensuring safety of a vehicle run comprising:
- a first control means for controlling a first factor for enhancing a running stability of a vehicle;
a second control means having a dangerous state judging means for detecting a running state of the vehicle and judging whether the running state is in a dangerous state to output a judgment signal;
said second control means automatically controlling a second factor relating to the running state of the vehicle so as to avoid a dangerous state judged by said dangerous state judging means, whereby the running state of the vehicle is automatically prevented from falling into a further dangerous state;
fail judging means for judging whether said first control means properly functions and for detecting when said first control means improperly functions and for generating an output signal; and
restricting means for restricting control for avoiding the dangerous state by said second control means when said fail judging means detects that said first control means is improperly functioning.

Abstract
A first control device regarding a running stability of a vehicle, such as an anti-skid braking system, a four wheel steering system, a four wheel driving device and a second control device for automatically avoiding the vehicle from being in a dangerous state, such as an automatic braking device, an automatic steering device are provided. Further provided is a fail judging device for judging a fail time when the first control device improperly works. The control for avoiding a danger by the second control device is restricted when the fail judging device judges the fail time of the first control device. Thereby, when the first control device fails, measures to automatically avoid the danger independent of a driver'"'"'s intention by such as an automatic braking, an automatic steering, is not taken. This previously prevents the vehicle from being unstable.

14. A control apparatus for ensuring safety of a vehicle run comprising:
-
a first control means for controlling a first factor for enhancing a running stability of a vehicle; a second control means having a dangerous state judging means for detecting a distance between the vehicle and a forward vehicle and judging the running state of the vehicle is in a dangerous state where the distance is smaller than a set value, and braking force applying means for applying a braking force of the vehicle so as to automatically reduce a running velocity of the vehicle when said dangerous state judging means judges that the distance is smaller than the set value, whereby a danger of contact between the vehicle and the forward vehicle is automatically avoided; fail judging means for judging whether said first control means properly functions and detecting when said first control means improperly functions and for generating an output signal; and restricting means for restricting control for avoiding the dangerous state by said second control means when said fail judging means detects that said first control means improperly functions. - View Dependent Claims (15)
