Abstract:
1. A deceleration control apparatus for an automotive vehicle, comprising: an accelerator pedal depression detecting unit that detects an accelerator pedal depression of the vehicle; a lateral acceleration detecting unit that detects an actual lateral acceleration of the vehicle; a yaw rate determination unit that determines an actual yaw rate of the vehicle; a road friction coefficient estimation unit that estimates a friction coefficient of a road on which the vehicle is traveling; a target vehicle speed calculation unit that calculates a target vehicle speed; and a deceleration control unit that performs deceleration control on the vehicle so that the vehicle reaches the target vehicle speed, the target vehicle speed calculation unit having: a first target vehicle speed calculating section to give as the target vehicle speed a first target vehicle speed value by dividing a multiplication product of the estimated road friction coefficient and a predetermined target lateral acceleration limit by the determined actual yaw rate; and a target vehicle speed correcting section to correct the target vehicle speed depending on the accelerator pedal depression and the detected actual lateral acceleration, so as to adjust the amount of said deceleration control on the vehicle.
