摘要： 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.

摘要： A vehicle includes an engine, electrical loads, and at least one controller. While the engine is on, the controller calculates the change in current demand of the electrical loads expected from turning the engine off. The decision to command the engine off is then based on the expected change in current demand. Electrical loads that will change state from on to off when the engine is turned off will increase the expected change in current demand. Electrical loads that will change state from off to on when the engine is turned off will decrease the expected change in current demand. Operating conditions associated with the electrical loads, such as operating voltage, temperature, and speed, may affect the expected change in current demand.

摘要： A method for operating an engine automatic stop-start system used in a motor vehicle fitted with an internal combustion engine. The system allows: automatic stoppings of the engine when a set of conditions outside and inside the vehicle are satisfied; automatic startings of the engine following an automatic stopping when at least one engine demand condition is met. The method includes an internal value which is a count of a number of operations of the system, wherein the internal value is subjected to a high threshold and to a low threshold, and the method can modify at least one of the conditions outside or inside the vehicle if the internal value reaches the low threshold or reaches the high threshold.

摘要： In a power-steering control system installed in a vehicle, a state determiner determines whether an engine is in a state in which the engine is stopped. A steering-torque detector measures steering torque applied to a steering wheel by a driver of the vehicle. A controller holds the power steering motor in a ready state to generate the assist torque if it is determined that the engine is in the stop state and that the measured steering torque is equal to or higher than first threshold torque.
