20100228453 | VEHICLE CONTROL SYSTEM DESIGNED TO MINIMIZE ACCELERATION SHOCK - A vehicle control system for an engine-powered vehicle equipped with an engine and an automatic transmission with a clutch. When a given engine stop requirement is met during running of the engine, the system stops the engine automatically. When a given engine restart requirement is met after stop of the engine, the system restarts the engine and enters a clutch control mode to bring the clutch in the automatic transmission into a slippable state in which the clutch is permitted to slip based on the speed of the vehicle, thereby absorbing the acceleration shock which usually occurs upon engagement of the clutch to transmit engine torque to wheels of the vehicle when the engine is restarted, and the speed of the vehicle is relatively low. | 09-09-2010 |
20100228460 | VEHICLE CONTROL SYSTEM CONTROLLING EXERTION OF BRAKING FORCE ON WHEEL - A vehicle control system is provided which is designed to stop or restart an engine automatically. The system is equipped with a vehicle speed determining circuit which determines the speed of the vehicle and has a dead zone around where a real speed of the vehicle is zero. The vehicle speed determining circuit has a characteristic in which when falling in the dead zone, the determined speed shows zero. When the determined speed is zero, and the real speed is expected to have dropped to zero, the system applies a first braking force to the wheel to keep the vehicle stopped. When the determined speed has become zero following the automatic stop of the engine, the system applies a second braking force smaller in magnitude than the first braking force to the wheel, thereby decelerating the vehicle slowly to avoid unexpected sudden deceleration. | 09-09-2010 |
20110256980 | VEHICLE CONTROL APPARATUS - A vehicle control apparatus includes: an automatic-stop-and-restart-control-unit stopping/restarting an engine, a brake-fluid-pressure-control-unit controlling wheel-cylinder-pressure using a brake-system, which intensifies brake-manipulation-force by a brake-booster to cause master-cylinder-pressure in a master-cylinder while the engine operates, and which transfers the master-cylinder-pressure to wheel-cylinders to cause the wheel-cylinder-pressure, the brake-system including an actuator automatically increasing pressure in the wheel-cylinders irrespective of the brake-manipulation-force; a negative-pressure-detection-unit which detects the vacuum-pressure; a first-determination-unit which determines whether the vacuum-pressure is not more than a first threshold while the engine stops, a restarting-unit which allows the automatic-stop-and-restart-control-unit to restart the engine when the first-determination-unit determines that the vacuum-pressure is not more than the first threshold; a second-determination-unit which determines whether the vacuum-pressure is not more than a second threshold; and a braking-boost-unit which allows the brake-fluid-pressure-control-unit to automatically increase the pressure in the wheel-cylinders when the second-determination-unit determines that the vacuum-pressure is not more than the second threshold. | 10-20-2011 |
20110256981 | APPARATUS FOR CONTROLLING AUTOMATIC STOP AND RESTART OF ENGINE - An apparatus for controlling automatic stop/restart of an engine, includes: an automatic-stop/restart-control-unit which stops/restarts the engine; a brake-pressure-detection-unit which detects brake pressure in a brake system and controls the brake pressure to perform anti-skid control; a first-determination-unit which determines whether the brake pressure is not less than a first-threshold; a second-determination-unit which determines whether the brake pressure is not less than a second-threshold larger than the-first threshold; a stop-allowing-unit which allows the automatic-stop/restart-control-unit to stop the engine while the engine operates, when the first-determination-unit determines that the brake pressure is not less than the first-threshold and the second-determination-unit determines that the brake pressure is less than the second-threshold; and a stop-inhibiting-unit which inhibits the automatic-stop/restart-control-unit from stopping the engine while the engine operates, when the-first-determination-unit determines that the brake pressure is less than the first-threshold and the second-determination-unit determines that the brake pressure is not less than the second-threshold. | 10-20-2011 |

20120080001 | ENGINE CONTROL APPARATUS - An engine control apparatus is configured to perform engine automatic stop to automatically stop an engine when predetermined engine stop conditions are satisfied and automatically restart the engine when predetermined engine restart conditions are satisfied. The stop conditions including that a vehicle speed decreases below a predetermined stop permission speed. The engine control apparatus includes a variation amount detection means for detecting a variation amount of a brake operation being performed by the vehicle driver during a deceleration period from when the vehicle has started to decelerate to when the vehicle speed has decreased below the stop permission speed, and a stop determination means for determining whether the engine automatic stop should be performed when the engine stop conditions are satisfied based on the variation amount detected by the variation amount detection means. | 04-05-2012 |
