“…And the controller design for the displacement control of clutch engagement as described in [5,6] is sensitive to the parameters, such as coefficient of friction disk, displacement of diaphragm spring or time constants for the actuator dynamics, etc., somehow reducing the performance of system. And the engaging speed of centrifugal clutch is usually fixed without considering the actual load conditions.…”

“…In practical application, starting resistance can be approximately estimated from the sensors or the initial brake pedal displacement when the vehicle is launched on a slope from standstill. Moreover, in some modern trucks, GPS signals and grade sensors can also be used to obtain the grade angle, and then improve the estimation accuracy of resistance torque [5]. The specific control flowchart for idle speed control strategy is shown in Fig.…”

Pomoćni uređaj za pokretanje direktno pogonjenog električnog vozila s regulatorom brzine praznog hoda motora STARTING ASSISTANCE DEVICE FOR DIRECTLY-DRIVEN ELECTRIC VEHICLE WITH VARIABLE-IDLE SPEED CONTROL Ping Xiong, Chenglin GuOriginal scientific paper By introducing a novel permanent magnetic bi-stable electromagnetic clutch unit (PMBECU) in the driveline of directly-driven electric vehicle, a flexible connection between motor and hub is realized with characteristic of separated starting process of drive motor and wheel load. Firstly, the working principle and power supply scheme for the PMBECU is discussed. Then the assembly for the wheel-drive system with starting assistance device by the clutch is investigated. Considering the good dynamic performance of wheel motor, variable-idle speed scheme is presented and the simplified model for fast clutch engagement is built and analyzed. Finally, the proposed method for directly-driven electric vehicle launch is performed on the test rig. The experimental results indicate the shock intensity and electromagnetic impulsion during the starting process is decreased effectively by clutch-coupling startup, which results in good driving comfort and less heat in armature winding of drive motor.

Najprije se raspravlja o načinu rada i shemi dovoda energije za PMBECU. Zatim se istražuje sklop za sustav pogona kotača s uređajem za pokretanje pomoću spojke. Razmatrajući dobre dinamičke karakteristike motora kotača, daje se shema promjenljivog praznog hoda te se gradi i analizira pojednostavljeni model za brzo ukapčanje spojke. Konačno se predložena metoda za pokretanje direktno pogonjenog električnog vozila primijenjuje na uređaju za ispitivanje. Eksperimentalni rezultati pokazuju da su jačina udara i elektromagnetski impuls tijekom pokretanja efikasno smanjeni pokretanjem zupčaste spojke, što rezultira udobnošću u vožnji i manjim zagrijavanjem namotaja armature pogonskog motora.Ključne riječi: direktno-pogonjeno električno vozilo; pomoć kod pokretanja; regulator brzine praznog hoda; sklop spojke; udobnost u vožnji

Original scientific paper The original rigid connection between the motor and the hub is replaced with a flexible one using the clutch to connect the driving and driven sides of the driveline system. Then the paper proposes a separable process of motor start-up and load operation, based on which the scheme of idle speed control is studied. Focusing on the contradiction between the extended torque capacity and the reduced vehicle jerk merely by tuning the idle speeds, an improved solution is proposed for toque compensation by throttle adjustment during the clutch engagement. Furthermore, the method for tracking the armature voltage of the driving motor is investigated and optimized, aiming at the balance between the demanded transmitted torque and the jerk level during the starting process. Finally, effectively enhanced torque capacity of the driving motor for the vehicle start-up on the premise of the improved comfort level has been demonstrated by experiments. Keywords: armature voltage compensation; direct-drive; flexible coupling; idle speed; vehicle jerkIstraživanje kompenzacije zakretnog momenta s optimalnom prigušnicom pedale za pokretanje električnog vozila izravnog stupnja prijenosa Izvorni znanstveni članak Originalna kruta veza između motora i glavine zamijenjena je fleksibilnom uporabom spojke za povezivanje pogonskog i gonjenog vratila sustava prijenosa. U radu se zatim predstavlja odvojeni proces pokretanja i opterećenja motora na osnovu kojega se analizira shema reguliranja rada motora u praznom hodu. Fokusiranjem na probleme koordinacije povećanog kapaciteta zakretnog momenta i smanjenja trzaja automobila samo regulacijom rada motora u praznom hodu, predlaže se poboljšano rješenje kompenzacije zakretnog momenta podešavanjem napona rotora dok se spojka aktivira gonjenom stranom. Nadalje, ispituje se i optimizira metoda za označavanje napona zakretnog momenta s ciljem stvaranja balansa između traženog prijenosnog mehanizma zakretnog momenta i jačine trzaja tijekom pokretanja vozila. Konačno, eksperimentima je demonstriran učinkovito poboljšani učinak zakretnog momenta pogonskog motora kod pokretanja vozila u svrhu povećane udobnosti.Ključne riječi: elastična spojka; izravni prijenos; kompenzacija napona rotora; rad motora u praznom hodu; trzaj vozila

“…Among systems for the control of vehicle dynamics, several laboratory and full-scale experiments on stability management, emergency braking operations, and traction control have shown potential further improvements of their performance [3,4]. The results have proven that modelling in detail frictional behaviour of brake pads/disc interaction for unsteady operating condition as sudden braking or brusque action of Traction control system/Electronic stability program system is an imperative topic for getting a breakthrough in the control strategies for braking/stability-control systems with continuously and not cyclically regulation [5].…”

This paper focuses on lab-scale testing of automotive dry-clutch materials and simulations of clutch engagement control in automated manual transmissions (AMTs). Simulations aim at virtualizing the vehicle launch manoeuvre as well as the role of transmission control unit (TCU) featuring different levels of training related to clutch material frictional response. The simulation results underline the essential requirement of friction coefficient accurate prediction in AMTs, particularly clutch temperature estimation in order to develop effective and reliable control algorithms.
