“…For the wheel direct drive, especially with in wheel motors, the Permanent Magnet Synchronous Motor (PMSP) is the reasonably, if not only possible solution, due to its relatively low mass which contribute to reduction of unsprung mass and to better drive comfort [14]. The PMSM is supplied by a battery b E through a DC/AC converter developed in [8] - [9].…”

Vehicle simulation software is essential to vehicle design and development. Most current vehicle software simulations, however, require that components be specified prior to running the simulations. Within this context, this paper presents a simulator offering to users flexibility enough to add new component and use different level of accuracy. Thus a first version of a new software tool, in order to assist in developing technologies for Electric Vehicle (EV), is described. The ELEctric VEhicle Simulator (ELEVES) is currently being developed as a research project in the University of Technology of Belfort-Montbéliard (UTBM) by our laboratory Systems and Transportations (SeT). This simulator is developed on the base of the Component Hybrid Dynamic Nets (CHDN). As application, the proposed software tool has been used to modeling and simulation of four motorized wheels electric vehicle. Finally, a comparison between the results obtained by ELEVES with those obtained by Matlab/ Simulink software tool has been included.

“…The continuous and precise modulation of each wheel driving torque in the 4WDEV gives it an advantage over centrally driven vehicles when carrying out vehicle motion control and in energy savings. For example, the vehicle yaw rate can be modified through differential control of wheels on distributed driven vehicles [3], moreover, properly distributing wheel torque under different circumstances can achieve high energy efficiency which meets the energy saving needs.…”

Abstract:The wheel driving torque on four-wheel-drive electric vehicles (4WDEVs) can be modulated precisely and continuously, therefore maneuverability and energy-saving control can be carried out at the same time. In this paper, a wheel torque distribution strategy is developed based on multi-objective optimization to improve vehicle maneuverability and reduce energy consumption. In the high-layer of the presented method, sliding mode control is used to calculate the desired yaw moment due to the model inaccuracy and parameter error. In the low-layer, mathematical programming with the penalty function consisting of the yaw moment control offset, the drive system energy loss and the slip ratio constraint is used for wheel torque control allocation. The programming is solved with the combination of off-line and on-line optimization to reduce the calculation cost, and the optimization results are sent to motor controllers as torque commands. Co-simulation based on MATLAB ® and Carsim ® proves that the developed strategy can both improve the vehicle maneuverability and reduce energy consumption.

This paper presents the implementation of an off-line optimized torque vectoring controller on an electric-drive vehicle with four in-wheel motors for driver assistance and handling performance enhancement. The controller takes vehicle longitudinal, lateral, and yaw acceleration signals as feedback using the concept of state-derivative feedback control. The objective of the controller is to optimally control the vehicle motion according to the driver commands. Reference signals are first calculated using a driver command interpreter to accurately interpret what the driver intends for the vehicle motion. The controller then adjusts the braking/throttle outputs based on discrepancy between the vehicle response and the interpreter command. A test vehicle equipped with four in-wheel electric motors, vehicle sensors, communication buses, and dSPACE rapid prototyping hardware is instrumented and the control performance is verified through vehicle handling tests under different driving conditions.
