Control of flywheel hybrid vehicle including throttle opening

A control unit 13 for a hybrid vehicle moves an engine throttle 15 to the wide open position whenever the driver wishes to decelerate. This maximises the transfer of rotational energy from the vehicle wheels 6 to a flywheel 12 which is coupled to a drivetrain 7,8,9 because pumping losses in the engine 2 are much reduced due to the open throttle. The energy stored in the flywheel 12 can be used at a later time to supplement the engine's motive power. The control unit 13 also controls an electro hydraulic clutch 11 which couples and decouples the flywheel to and from the drivetrain through a continuous variable transmission 10. The gear ratio of the continuous variable transmission 10 is set by the electronic control unit 13.

Eine Fahrzeuggetriebeantriebswelle 4, 8 treibt durch einen Umlaufgetrieberadsatz 12 eine Elektromaschine 11 an und kann von ihr angetrieben werden. Ein Rotor 10 der Elektromaschine ist mit einem Sonnenrad 13 verbunden, und ein Planetenradträger 14 ist mit der Getriebeantriebswelle 4, 8 verbunden. Ein Hohlrad 15 wird über eine Hohlradkupplung 16 mit einem Gehäuse 5 verriegelt, um eine Antriebsverbindung zwischen der Antriebswelle 4, 8 und dem Rotor 10 bereitzustellen. Durch Trennen der Hohlradkupplung 16 bei Gangwechseln wird verhindert, dass die Trägheit des Rotors 10 in die Antriebswelle 4, 8 zurückgelenkt wird.

Hybrid vehicle control apparatus and method

Hybrid vehicle with a stability control module and a drivetrain that includes a flywheel

A hybrid vehicle comprises a prime mover such as an internal combustion engine 2 and a flywheel 9 as a secondary mover. The engine 2 is connected via a gearbox and final drive assembly 4 to a first set of wheels 3. Flywheel 9 drives a second set of wheels 5 and is part of a drivetrain comprising a differential 7, a propshaft 8, an electro hydraulic clutch 11, an oil pump 12, reduction epicyclic gearing 13 and, for example, a continuously variable transmission (CVT) 10. An electronic control module (ECM) 14 receives inputs form various sensors 16, 17, 18 and from a stability control module 24 which, via the ECM 14, sends a signal to the drivetrain that is configured to operate in response to the signal. The arrangement permits all wheel drive and stability control of the hybrid vehicle.

Flywheel drive control arrangement

In an energy storage and recovery system suitable for a hybrid vehicle 1 and incorporating a flywheel 9, parasitic losses are minimised, thereby permitting a rotating flywheel to retain energy for a longer period of time. The flywheel is driven via an epicyclic gearset 13. An electro-hydraulic clutch 14 serves to decouple the annulus gear 21 so that it does not transmit any torque under certain vehicle operating conditions.

Hybrid vehicle and control method

A hybrid vehicle 1 incorporates a flywheel-based energy storage and recovery system 10 which can drive or be driven by the input shaft 4 of an automatic manual shift gearbox 5. The arrangement minimises vehicle driveline lash. The energy storage system 10 is provided at an end of the input shaft 4 and in alternative arrangements may comprise an electric machine and a battery. Control methods may include detecting vehicle acceleration or deceleration demand and controlling two clutches 6, 11 and the gearbox 5. A prime mover 2 such as an engine or electric motor is provided at the other end of the input shaft 4, ...

Mass measurement of a flywheel hybrid vehicle

A hybrid vehiclel is equipped with an engine 2, a secondary mover consisting of a flywheel 12 and a continuously variable transmission (CVT) 10. A mass of the vehicle 1 may be determined by measuring a rate of change of the CVT ratio while rotational energy is being transferred to the flywheel 12. The rate of change may be measured by rotation speed sensors 16, 17 placed either side of the CVT 10 and having outputs connected to an electronic measurement module (EEM) 13. An electronic control module (ECM) communicates with the EEM 13 that also receives an input from an accelerator pedal 15. A store 14 located in the EEM 13 contains a value for a moment of inertia of the flywheel 12 and vehicle calibration data. The moment of inertia and the data is used with an acceleration demand to compute a rate of change of the CVT 10 which is compared with an expected value, a difference between the computed value and the expected value is proportional to the mass increase of the vehicle.

Hybrid vehicle control apparatus and method

A hybrid vehicle has an internal combustion engine 2 and a flywheel 9. Storage and release of energy by the flywheel 9 is enabled by a continuously variable transmission 10 and clutch 11 under the control of an electronic module 14. The amount of energy transferred from the vehicle one to the flywheel 9 during a deceleration manoeuvre is maximized by increasing the engine speed. As a result, the engine does more work against the braking force of the accelerating flywheel and causes the flywheel to spin up to a higher rotational speed. A braking system vacuum pump assists the operation a flywheel housing vacuum pump. Periodic braking effort modulation may be provided to prevent seizure of braking system components while minimizing concomitant losses.
