摘要:
Es wird ein Verfahren zum Betrieb eines Kraftfahrzeuges (2) sowie ein Kraftfahrzeug (2) angegeben, welches eine elektrische Maschine (12), zur positiven oder negativen Beschleunigung des Kraftfahrzeuges (2) sowie eine mechanische Bremsvorrichtung (16) zur Reduzierung der Geschwindigkeit des Kraftfahrzeuges (2) aufweist. In einem speziellen Brems-Betriebsmodus wird eine Verzögerungsanforderung (V) erfasst und in Abhängigkeit der Verzögerungsanforderung (V) ein Solldrehzahlverlauf (n soll ) der elektrischen Maschine (12) ermittelt. Eine Istdrehzahl (n ist ) der elektrischen Maschine (12) wird anschließend zur Reduzierung der Geschwindigkeit des Kraftfahrzeuges (2) an den ermittelten Solldrehzahlverlauf (n soll ) angepasst.
摘要:
A construction vehicle control apparatus is provided including: a motor generator control unit (160) which, when regenerative electrical power generated by a motor (7) during regenerative braking surpasses acceptable charging electrical power of a capacitor (3), drives a motor generator (5) using the surplus electrical power; an engine controller (2) which detects the rotating speed of an engine (1); a motor control unit (180) which, if the rotating speed of the engine becomes larger than a second set value while the motor generator is being driven by the surplus electrical power, reduces regenerative torque generated by the motor; and a brake control unit (190) which, if the rotating speed of the engine becomes larger than the second set value while the motor generator is being driven by the surplus electrical power, increases regenerative torque generated by a hydraulic brake (30).
摘要:
The invention relates to a vehicle (1) including: - a towing axle (3) connected to a heat engine (5); - a directional axle (2); and - a complementary axle (4) that is neither directional nor motor-driven. When said vehicle is hybridized according to the method of the invention, the wheels of the complementary axle (4) are removed and replaced by in-wheel motors (12a, 12b), each connected with an inverter (13a, 13b) specifically dedicated for supplying electrical power thereto from an electrical power battery (14). A control housing (16) is also provided, that has built-in acceleration control means connected to the accelerator pedal (7), and built-in deceleration control means connected to the brake pedal (8), so as to control and monitor all the means needed for the driver to transparently accelerate and decelerate the vehicle.
摘要:
Braking force is distributed between at least one friction brake for at least one pair of wheels and at least one brake for applying a braking force to at least one driven pair of wheels via the transmission. The braking force distribution system is located in front of the clutch for the transmission.

摘要:
A drive device 1A includes: electric motors 2A and 2B that outputs drive powers; and planetary gear reducers 12A and 12B disposed between axles 10A and 10B connected to cylindrical shafts 16A and 16B serving as the output shafts of the electric motors 2A and 2B and to rear wheels LWr and RWr. The drive device 1A further includes: a one-way power transmission device that transmits the one-way rotation power of the electric motors 2A and 2B to the axles 10A and 10B; and a two-way power transmission device that transmits the two-way rotation power of the electric motors 2A and 2B to the axles 10A and 10B. The one-way power transmission device and the two-way power transmission device are disposed on transmission passages from the electric motors 2A and 2B to the axles 10A and 10B.
