System for restarting internal combustion engine when engine restart request occurs

Номер: US20120035837A1
Принадлежит: Denso Corp

In a system, a starter includes a motor for rotatably driving an output shaft with a pinion and an actuator that shifts the pinion toward a ring gear to be engaged with the ring gear. A monitor unit monitors a rotational speed of the internal combustion engine. The rotational speed of the internal combustion engine drops after an automatic control for stop of the engine. When an engine restart request occurs with the rotational speed being within a preset range during the rotational speed of the internal combustion engine dropping by the automatic control for stop of the engine, a drive unit drives the actuator to shift the pinion toward the ring gear to be engaged with the ring gear. The drive unit rotatably drives the motor with the pinion being engaged with the ring gear to thereby crank the crankshaft.

Engine cranking motor soft-start system and method

Номер: US20130062891A1
Автор: Frank J. Bourbeau
Принадлежит: Enerpro Inc

An engine cranking motor soft-start system and method includes at least one cranking motor and a switching power converter which is coupled to the cranking motors such that the voltage across the motors varies with the converter's duty cycle. The duty cycle, and thereby the voltage across the motors, is gradually increased over a predetermined period. This serves to limit the acceleration of the cranking motors, and thereby their peak current and torque, which may serve to increase their service life. The cranking motors are typically operatively coupled to drive respective pinion gears which are brought into engagement with a ring gear when starting the engine. The system is preferably arranged such that the gradually increasing duty cycle results in the torque of the cranking motors being sufficient to break an abutment that may be present between the pinion gears and the ring gear.

The control apparatus restricts rotation of the electric motor so as to keep a speed of the electric motor below a speed at which the electric motor is capable of producing a maximum torque until a given period of time passes since the electric motor is actuated to start in the motor mode. This enables the electric motor to generate the maximum torque when it is required to crank the engine.

Принадлежит: FORD GLOBAL TECHNOLOGIES LLC

A system and method for controlling engine idle stop in a hybrid vehicle balance the extra electrical load imposed on the vehicle during engine stop with the electrical energy saved to achieve net fuel savings. Predictive information is used to determine potential vehicle stops and corresponding stop durations during a time window. To achieve net fuel savings, the engine stop duration time must be long enough for the electrical energy savings to cover electrical load added to the system. If the predicted stop duration time is long enough to yield net fuel savings, engine stop may be initiated. If not, engine stop may be inhibited.
