Vehicle control system
First Claim
1. A vehicle control system comprising:
- means for controlling a running condition of a vehicle by setting a target control amount based on a distance from and relative speed with respect to an object present ahead of the vehicle and accelerating or decelerating the vehicle according to the target control amount;
means for performing control for avoiding a collision with the object if the collision cannot be avoided by the control performed by the running condition control means; and
means for canceling an operation mode for allowing the running condition control means to perform control if control by the collision avoiding control means is activated when the operation mode is active.

Abstract
In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle'"'"'s control in a reliable manner. When a set switch is turned on in the “cancel” state, the transition to the “in-control, inter-vehicle distance control” sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the “in-control, collision alarm” sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the “in-control, collision avoiding control” sub-state, and a collision avoiding control is performed.

3. A vehicle control system comprising:
-
means for controlling a running condition of a vehicle by setting a target acceleration based on a distance from and relative speed with respect to an object ahead of the running vehicle and accelerating or decelerating the vehicle according to the target acceleration; and
means for performing control for avoiding collision if a collision with the object cannot be avoided by the control performed by the running condition control means, wherein the running condition control means performs actual control with the target acceleration limited to a limit acceleration that is preset to a negative value if the target acceleration is smaller than the limit acceleration;
the collision avoiding control means performs control with an avoidance acceleration that is smaller than the limit acceleration at least at the start of the control; and
the avoidance acceleration is set such that a perceivable difference to the driver is generated between behaviors of the vehicle during control by the running condition control means and during control by the collision avoiding control means. - View Dependent Claims (4, 5, 6, 8, 9, 10)

7. A vehicle control system comprising:
-
means for controlling a running condition of a vehicle by setting a target control amount based on a distance from and relative speed with respect to an object present ahead of the vehicle and accelerating or decelerating the vehicle according to the target control amount;
means for performing control for avoiding collision if a collision with the object cannot be avoided by the control performed by the running condition control means;
means for generating an alarm when the possibility is high that the collision avoiding control means is activated; and
means for inhibiting operation of the collision avoiding control means if a specified operation indicating that no control by the collision avoiding control means is necessary is detected in a period after activation of the alarm means and before activation of the collision avoiding control means.
