Abstract
A driving assisting for calculating risk potential by considering a response delay by the driver and transmitting information related to the risk potential to the operator in a haptic manner. A controller is provided to estimate the response delay based on an operation performed by the operator. Based on the estimated response delay, the controller calculates a future position at which the risk potential is to be calculated. The longer the response delay, the remoter the future position is. The shorter the response delay, the nearer the future position is. The calculated risk potential at the future position may be transmitted to the operator via a pressing force from one of right and left side portions of a driver'"'"'s seat occupied by the operator.

9. A system for assisting an operator in operating an own vehicle, the system comprising:
-
a detector configured to detect a driving environment around the own vehicle; a response delay estimating device configured to estimate a response delay by the operator; a risk potential calculating device configured to calculate risk potential associated with the own vehicle at a future position based on the detected driving environment and the estimated response delay; and an operation detecting device configured to detect an operation performed by the operator, wherein the response delay estimating device estimates the response delay based on the detected operation, wherein a standard deviation of the detected operation is calculated; and the estimated response delay is estimated based on the calculated standard deviation of the detected operation. - View Dependent Claims (10)

14. A system for assisting an operator in operating an own vehicle, the system comprising:
-
a detector configured to detect a driving environment around the own vehicle; a response delay estimating device configured to estimate a response delay by the operator; and a risk potential calculating device configured to calculate risk potential associated with the own vehicle at a future position based on the detected driving environment and the estimated response delay, wherein the future position is set to vary with the estimated response delay, wherein a standard deviation of an in-lane lateral position of the own vehicle within a lane is calculated; and the response delay is estimated based on the standard deviation of the in-lane lateral position of the own vehicle within a lane.

20. In a vehicle having a steering wheel of a steering system manipulated by an operator:
-
a front camera mounted to the vehicle and configured to pick up an image of a road ahead of the vehicle; a vehicle speed sensor mounted to the vehicle configured to detect a vehicle speed of the vehicle; an operation detector attached to the steering system and configured to detect a steering angle of the steering wheel; a driver'"'"'s seat mounted to the vehicle and occupied by the operator, the driver'"'"'s seat including a right side portion and a left side portion; a seat side actuator assembly including a right side actuator configured to swing the right side portion toward the operator in response to a seat right side control signal indicative of a seat side swing angle for the right side portion, and a left side actuator configured to swing the left side portion toward the operator in response to a seat left side control signal indicative of a seat side swing angle for the left side portion; and a controller configured to calculate a response delay index; calculate a lead time using the calculated response delay index; calculate a future position, which the vehicle will reach upon elapse of the calculated lead time based on the detected, based on the image picked up by the front camera, the vehicle speed detected by the vehicle speed sensor, the steering angle detected by the operation detector; calculate risk potential around the vehicle at the calculated future position; calculate the seat side swing angles for the right and left side portions, respectively; and generate the seat right side control signal and the seat left side control signal indicative of the seat side swing angles. - View Dependent Claims (21, 22, 23, 24)
