20090112438 | VEHICLE RUNNING CONTROL APPARATUS - A disclosed vehicle running control apparatus is capable of reliably detecting the operation of the brake pedal by the driver. The vehicle running control apparatus is installed in a vehicle and is capable of performing vehicle control so that the vehicle runs at a prescribed speed and controlling a brake booster during a deceleration process to generate a master cylinder pressure so that the vehicle runs at a prescribed decelerated speed. The vehicle running control apparatus includes a switching unit that is installed in the brake booster and is turned ON when a brake pedal of the vehicle is pressed; a detecting unit detecting the master cylinder pressure; and a control stopping unit stopping the vehicle control when the switching unit is turned OFF and the master cylinder pressure detected by the detecting unit is greater than a prescribed threshold value. | 04-30-2009 |
