Abstract:

A torque vectoring system is designed for the hybrid electric–all wheel drive vehicle where the front and rear wheels are powered by the combustion engine and electric motors, respectively. The vehicle provides enhanced handling performance by a twin motor drive unit that can distribute the driving and regenerative braking torques to the rear-left and rear-right wheels independently. Based on the driver’s intention, a sliding mode controller is designed to calculate the desired traction force and yaw moment for the vehicle.

Abstract The aim of this study is to show the results of the vehicle research group redesigned a Volkswagen Crafter diesel type van to a multi hybrid vehicle. The original chassis of the four-wheel drive van provides the base of the vehicle. The electric motor and the gearbox designed by the research group is placed in front of the rear suspension. This electric drive unit is coupled to the rear differential via the Haldex clutch. During the electric drive the transaxle of the van is in neutral gear and the diesel engine is not operating. Releasing the Haldex clutch the electric drive is detac

   A through-the-road (TTR) hybrid electric vehicle (HEV) is a sub-type of the parallel hybrid, in which the internal combustion engine (ICE) and electric motor provide propulsion power to different axles. TTR architecture allows for hybrid conversion of an existing vehicle using in- wheel motors (IWM), as alternative to on-board motor. Operation requires different types of signals to be acquired and processed: hardwire low- voltage analog signals, digital pulse-train and CAN-bus signals. This work discusses system integration in a TTR hybrid: motor controller, engine control

Switched reluctance motors (SRMs) are highly advantageous electric motors for various industrial applications, particularly in electric vehicles (EVs), due to their winding-free rotor, magnet-free design, simplicity, and ease of manufacturing. The growing interest in axial flux SRMs (AFSRMs) is particularly noticeable, as axial flux electric motors with a flat shape and high aspect ratio have become commonly used in various industrial applications, including in-wheel motors for EVs. Structurally, AFSRMs significantly differ from radial flux SRMs (RFSRMs), but share the same electromagnetic ope

This paper presents an active safety device for skid control of small electric vehicles with in-wheel motors. Due to the space limitation on the driving tire, a mechanical brake system was installed rather than hydraulic brake system. For the same reason, anti-lock brake system (ABS) that is a basic skid control method cannot be installed on the driving tire. During braking on icy road or emergency braking, the tire will be locked and the vehicle is skidding. To prevent tire lock-up and vehicle from skidding, we proposed the combination of ABS and regenerative brake timing control. The hydraul

The traffic on such road sections may be accompanied by resonance oscillations of the wheels with their separation from the road. This causes a decrease in stability of the vehicle. To combat this phenomenon the new system of active safety of the cat could be applied - stabilization system of the vertical reactions of the road on the wheel when driving on a periodic profile.
