Stability control device of vehicle prepared for manual brake uprise subsequent to end of stability control
First Claim
1. A stability control device of a vehicle having a vehicle body, and front left, front right, rear left and rear right wheels, comprising:
- a means for estimating a liability of the vehicle body to a running instability for producing an instability quantity which generally increases along with increase of the liability;
a brake means for selectively applying a variable braking force to each of said wheels, said brake means including a manually controlled pressure source means incorporating a brake pedal and an accumulator pressure source means;
a manual brake sensing means for detecting a substantial stepping on of said brake pedal by a driver; and
a control means for controlling said brake means so as variably to apply a braking force to a selected one or ones of said wheels for a stability control of suppressing the vehicle body against the running instability based upon accumulator pressure from said accumulator pressure source means, said control means controlling said brake means so that a braking force is applied to the wheels based upon said manually controlled pressure source means when said stability control is not carried out,wherein, when the substantial stepping on of said brake pedal is detected by said manual brake sensing means when said control means ends said stability control, said control means controls said brake means so that the braking force based upon said manually controlled pressure source means is applied to the wheels under a controlled uprise rate.

Abstract
A stability control device of a vehicle includes a device for estimating a liability of the vehicle body to a running instability for producing an instability quantity which generally increases along with increase of the liability; a brake device for selectively applying a variable braking force to each wheel, the brake device including a manually controlled pressure source incorporating a brake pedal and an accumulator pressure source; a manual brake sensor for detecting a substantial stepping on of the brake pedal by a driver; and a controller for controlling the brake device so as to variably apply a braking force to a selected one or ones of the wheels for a stability control of suppressing the vehicle body against the running instability based upon the accumulator pressure, the controller controlling the brake device so that a braking force is applied to the wheels based upon the manually controlled pressure source when the stability control is not carried out, wherein, when the substantial stepping on of the brake pedal is detected by the manual brake sensor when the controller has finished the stability control, the controller controls the brake device so that the braking force based upon the manually controlled pressure source is applied to the wheels under a controlled uprise rate.
