Deceleration control apparatus for vehicle

Abstract

A deceleration control apparatus for a vehicle including a controller that performs deceleration control based on a first target deceleration set based on a distance to a starting point of an upcoming curve, when the deceleration control for the curve is started at a position distant from the starting point of the curve; and that performs the deceleration control based on a second target deceleration set based on a lateral acceleration that is estimated to be detected when the vehicle passes the starting point of the curve, when the deceleration control for the curve is started at a position close to the starting point of the curve. With this apparatus, it is possible to perform the deceleration control that provides drive assist according to the intention of the driver and that enhances driving convenience for the driver.

1 . A deceleration control apparatus for a vehicle, comprising:
 a controller that selects one of a first target deceleration set based on a distance to a starting point of an upcoming curve and a second target deceleration set without taking the distance to the starting point of the curve into account, and that performs deceleration control based on one of the first target deceleration and the second target deceleration that is selected.   
     
     
         2 . The deceleration control apparatus for a vehicle according to  claim 1 , wherein
 one of the first target deceleration and the second target deceleration, at which a degree of deceleration is lower, is selected.   
     
     
         3 . The deceleration control apparatus for a vehicle according to  claim 1 , wherein
 the second target deceleration is set based on a lateral acceleration that is estimated to be detected when the vehicle passes the starting point of the curve.   
     
     
         4 . The deceleration control apparatus for a vehicle according to  claim 1 , wherein
 the second target deceleration is set based on a difference between a lateral acceleration that is estimated to be detected when the vehicle passes the starting point of the curve and another lateral acceleration used as a target lateral acceleration when the vehicle goes round the curve.
