SPEED CONTROL DEVICE FOR VEHICLE
First Claim
1. A speed control device for a vehicle comprising:
- a vehicle speed obtaining means for obtaining a speed of the vehicle;
a shape obtaining means for obtaining a shape of a curve existing ahead of the vehicle;
a position obtaining means for obtaining a positional relationship between the curve and the vehicle;
a target vehicle speed determining means for determining a target vehicle speed in a case where the vehicle travels through the curve, on the basis of the shape of the curve and the positional relationship;
a vehicle speed controlling means for controlling the speed of the vehicle on the basis of the target vehicle speed and the speed of the vehicle; and
an acceleration operation quantity obtaining means for obtaining an operation quantity of an acceleration operating member, which is to be operated by a driver of the vehicle, whereinthe target vehicle speed determining means includes a modification means for modifying the target vehicle speed on the basis of the operation quantity so that the target vehicle speed in a case where the operation quantity is greater than zero becomes a greater value than the target vehicle speed in a case where the operation quantity is zero.

Abstract
A speed control device for a vehicle includes a vehicle speed obtaining means obtaining a vehicle speed, a shape obtaining means obtaining a curve shape, a position obtaining means obtaining a positional relationship between a curve and the vehicle, a target vehicle speed determining means determining a target vehicle speed based on the curve shape and the positional relationship, a vehicle speed controlling means controlling the vehicle speed based on the target vehicle speed and the vehicle speed, and an acceleration operation quantity obtaining means obtaining an operation quantity of an acceleration operating member operated by a driver, wherein the target vehicle speed determining means includes a modification means modifying the target vehicle speed based on the operation quantity so that the target vehicle speed obtained when the operation variable is greater than zero becomes a greater value than the target vehicle speed obtained when the operation quantity is zero.

9. A speed control device for a vehicle comprising:
-
a vehicle speed obtaining means for obtaining a speed of the vehicle; a shape obtaining means for obtaining a shape of a curve existing ahead of the vehicle; a reference determining means for determining an appropriate vehicle speed, by which the vehicle is to appropriately travel through the curve, and a reference point, which exists on the curve and which is a point by which the speed of the vehicle is to be decreased down to the appropriate vehicle speed, on the basis of the shape of the curve; a distance obtaining means for obtaining a relative distance of a zone between the reference point and the vehicle; a target vehicle speed determining means for determining a target vehicle speed for decreasing the speed of the vehicle down to the appropriate vehicle speed on the basis of the reference point, the appropriate vehicle speed and the relative distance; a vehicle speed controlling means for controlling the speed of the vehicle on the basis of the target vehicle speed and the speed of the vehicle; and an acceleration operation quantity obtaining means for obtaining an operation quantity of an acceleration operating member, which is to be operated by a driver of the vehicle, wherein the target vehicle speed determining means includes a modification means for modifying the target vehicle speed on the basis of the operation quantity so that the target vehicle speed in a case where the operation quantity is greater than zero becomes a greater value than the target vehicle speed in a case where the operation quantity is zero. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
